These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure.

With the continuous development of earphone technology and the continuous improvement of consumption level of people, various types of earphones, such as headphones, earphones, in-ear earphones and the like, come up endlessly, and the demand of people for earphones is more and more diversified. In the process of using the earphone, the state of the earphone, such as whether the earphone is worn in place or whether the earphone blocks a hole, is also an important factor affecting the audio playing effect and the user experience.

In an example, whether wear the example that targets in place with the earphone, when the user worn the earphone, under the condition of wearing the condition that targets in place, the skin laminating degree of earphone and user's ear department is higher, and the noise reduction effect of earphone is good, and the tone quality of its broadcast audio frequency can be better, otherwise, if the mode of wearing the earphone is inaccurate, and the earphone does not wear to target in place promptly, and the noise reduction effect of earphone is relatively poor, and the tone quality of its broadcast audio frequency can be relatively poor, reduces user's sense of hearing and experiences.

In the embodiment of the present disclosure, the earphone is worn in place means that the earphone is worn at a suitable position of the ear of the user, when the earphone is worn in place, the audio played by the earphone can reach better tone quality, and the influence of external noise on the audio played by the earphone is small or even no influence; the condition that the position of the earphone is not proper means that the position of the earphone is not proper, the tone quality of the audio played by the earphone is poor, and the influence of external noise on the audio played by the earphone is large.

The embodiment of the present disclosure provides a state detection method for an earphone, which can collect a first sound signal by using a microphone in the earphone under a condition that the earphone is not worn, and collect a second sound signal by using the microphone under a condition that the earphone is worn, wherein since the first sound signal and the second sound signal are from the same sound source, a state of the earphone can be determined according to a difference between a sound pressure corresponding to the first sound signal and a sound pressure corresponding to the second sound signal, so as to accurately detect at least one of whether the earphone is worn in place and whether the earphone blocks a hole. Referring to fig. 1, fig. 1 is a schematic flow chart of a method for detecting a state of an earphone according to an embodiment of the present disclosure, where the method may be executed by the earphone, and the method includes:

in step S101, a first sound signal is acquired using a microphone in the headset under a condition that the headset is not worn.

Acquiring a second sound signal using the microphone under the condition that the headset is worn in step S102; wherein the first sound signal and the second sound signal are from the same sound source.

In step S103, a state of the earphone is determined according to a difference between a sound pressure corresponding to the first sound signal and a sound pressure corresponding to the second sound signal, where the state of the earphone includes at least one of whether the earphone is worn in place and whether the earphone blocks the hole.

For example, the greater the difference between the sound pressure corresponding to the first sound signal and the sound pressure corresponding to the second sound signal, the greater the likelihood that the headset is worn in place. The smaller the difference between the sound pressure corresponding to the first sound signal and the sound pressure corresponding to the second sound signal, the less the earphone may not be worn in place or a hole blockage situation may occur.

One method for detecting whether the headset is worn in place in the related art is: when the earphone is worn, the earphone plays a preset audio, and sound pressure corresponding to an audio signal of the preset audio collected by a microphone in the earphone is compared with a reference sound pressure threshold value to determine whether the earphone is worn in place, for example, when the sound pressure corresponding to the audio signal is greater than or equal to the reference sound pressure threshold value, it is determined that the earphone is worn in place. The reference sound pressure threshold is set when the earphone leaves a factory, and with the increase of the using time of the earphone or the blockage of the sound hole of the earphone by dirt and other conditions, components in the earphone are affected, so that the sound pressure of the earphone when playing the preset audio also changes, correspondingly, the sound pressure of the audio signal of the preset audio collected by the microphone also changes, which easily causes a misjudgment condition, for example, when the sound pressure of the audio signal is blocked by dirt, the sound pressure of the audio signal is greater than the reference sound pressure threshold, so that the condition that the earphone is not worn in place but is misjudged as being worn in place is generated, and obviously, the detection result of whether the earphone is worn in place is wrong.

In the embodiment of the disclosure, the state of the earphone is detected based on the sound pressure difference of the sound signal of the same sound source when the earphone is worn or not worn, and the states of the physical components in the earphone and the like are basically the same or have small difference when the earphone is worn or not worn, so that the influence of physical factors (such as abrasion of the earphone, blockage of at least part of a sound hole of the earphone by dirt and the like) can be effectively offset, and the earphone state detection accuracy is improved.

In some embodiments, the state detection method of the headset may be performed by the headset, e.g. the state detection method of the headset may be in the form of executable instructions stored in a memory of the headset, which may be performed by a processor in the headset. Illustratively, the headphones include, but are not limited to, headphones, ear buds, in-ear headphones, and the like, which may be wired headphones or wireless headphones, such as a true wireless stereo TWS headphone, and the like.

In some embodiments, the state detection method of the headset according to the embodiments of the present disclosure may be executed in response to a user instruction, that is, a user may determine whether to start a headset state detection function indicated by the state detection method according to actual needs, for example, the headset is provided with an appointed control, the appointed control is used for instructing to execute the headset state detection function, and the headset executes the state detection method of the headset according to the embodiments of the present disclosure in response to a trigger operation of the appointed control; or a terminal associated with the earphone is provided with a designated control, the terminal can send an execution instruction of the earphone state detection function to the earphone when the designated control is triggered by a user, and the earphone responds to the execution instruction to execute the earphone state detection method of the embodiment of the disclosure.

In other embodiments, the method for detecting the state of the headset provided in the embodiments of the present disclosure may also be automatically executed in real time in the headset, which is not limited in this embodiment, and may be specifically set according to an actual application scenario.

In some embodiments, the headset is provided with a distance sensor, and the headset can determine whether the headset is worn according to the detection value of the distance sensor in the headset. For example, referring to fig. 2, the distance sensor of the earphone includes two preset detection thresholds, which are a preset proximity threshold x and a preset distance threshold y, respectively, where the preset proximity threshold x is greater than the preset distance threshold y, and if a detection value of the distance sensor is greater than the preset proximity threshold, it is determined that the earphone is worn; if the detection value is smaller than the preset departure threshold value, it is determined that the headset is not worn, for example, in fig. 2, assuming that the current reading value (i.e., the current detection value) of the proximity sensor is z, when z > x, it is determined that the headset is worn, and when z < y, it is determined that the headset is not worn.

In other embodiments, it may also be determined whether the headset is worn by the state of the headset, such as when the headset is in a charging state, determining that the headset is not worn.

For example, in order to further improve the accuracy of state detection, it may also be determined whether the headset is worn by taking into consideration the detection value of the distance sensor and the state of the headset, for example, if the detection value of the distance sensor is smaller than a preset distance threshold value and the headset is currently in a charging state, it is determined that the headset is not worn; and if the earphone is in a non-charging state currently and the detection value is larger than a preset approach threshold value, determining that the earphone is worn.

It can be understood that the wearing state of the earphone can also be determined in other manners, which is not limited in this embodiment, for example, whether the earphone is worn or not can be determined by the infrared temperature measurement sensor, for example, if the temperature measured by the infrared temperature measurement sensor is within a preset ear temperature range, it is determined that the earphone is worn, and if the temperature measured by the infrared temperature measurement sensor is outside the preset ear temperature range, it is determined that the earphone is not worn.

In some embodiments, a microphone in the earphone may be used to collect a first sound signal when the earphone is not worn and to collect a second sound signal when the earphone is worn, where the first sound signal and the second sound signal are from the same sound source, so that whether the earphone is worn in place or not may be determined based on a sound pressure difference of the same sound source before and after the earphone is worn, and then physical factors (such as wear of the earphone, blockage of at least a part of a sound hole of the earphone by dirt, and the like) have substantially the same or a small difference on both wearing and non-wearing conditions of components in the earphone, so that the influence of the physical factors on the sound pressure may be effectively cancelled, and the accuracy of earphone status detection may be improved.

It is here exemplarily explained that the first sound signal and the second sound signal are from the same sound source:

in a possible implementation manner, the first sound signal and the second sound signal are acquired by the microphone when the earphone plays a preset audio. In consideration of the fact that if the preset audio is directly played under the condition that the user does not allow, if the situation of playing the audio is not appropriate, for example, the user is in a place requiring low volume, the use experience of the user is obviously seriously affected. Therefore, if the first sound signal and the second sound signal are collected in a manner that a preset audio is played by an earphone, the state detection function of the earphone needs to be performed only under the condition that a user confirms, that is, if the earphone receives a user instruction, the preset audio can be played respectively before the earphone is worn and after the earphone is worn in response to the user instruction; and if the earphone does not receive the user instruction, the preset audio is not played.

In the case of receiving the user instruction, for example, in a condition that the headset is not worn, the headset may control a speaker in the headset to play preset audio in response to the user instruction, and simultaneously acquire the preset audio using a microphone in the headset to obtain a first sound signal; under the condition that the earphone is worn, the earphone can respond to the user instruction to control a loudspeaker in the earphone to play preset audio, and meanwhile, a microphone in the earphone is used for collecting the preset audio to obtain a second sound signal, so that two sound signals of the same sound source before and after the earphone is worn are obtained. It can be understood that, the triggering manner of the user instruction is not limited in any way in the embodiments of the present disclosure, and may be specifically set according to an actual application scenario.

In another possible implementation manner, in order to further improve efficiency, the earphone is not required to play preset audio, but environment sound is directly collected to detect whether the earphone is worn in place, that is, the first sound signal and the second sound signal are environment sound signals, so that a detection process is facilitated to be simplified, whether the earphone is worn in place is detected under the condition that a user does not sense, and the use experience of the user is facilitated to be improved. In addition, as the collected environment sound signals are not sensed by the user, the state detection function of the earphone can be performed under the condition that the user confirms, and the state detection function of the earphone can also be automatically performed according to the actual condition.

Of course, in addition to the two sound sources exemplified above, other sound sources can be used according to actual situations, and the embodiment does not limit this.

In some embodiments, taking the first sound signal and the second sound signal as an example of an ambient sound signal, please refer to fig. 3, where fig. 3 is another schematic flow chart of a method for detecting a state of an earphone according to an embodiment of the present disclosure, the method includes:

in step S201, an ambient sound signal is collected at a certain frequency using the microphone under the condition that the headset is not worn, and the collected ambient sound signal is stored.

In step S202, an ambient sound signal is collected using the microphone under the condition that the headset is worn.

In step S203, determining a state of the earphone according to a difference between a stored sound pressure corresponding to the most recently collected environment sound signal and a stored sound pressure corresponding to the environment sound signal collected under the condition that the earphone is worn, wherein the state of the earphone includes at least one of whether the earphone is worn in place and whether the earphone blocks a hole.

In order to ensure that environmental sounds in the same environment are substantially consistent or have a small difference when the first sound signal and the second sound signal are collected, it may be required that collection intervals of the first sound signal and the second sound signal are close to each other when the first sound signal and the second sound signal are collected, for example, the collection interval of the first sound signal and the second sound signal is not greater than a preset time interval, such as not greater than 30 seconds, and the preset time interval is several to several tens of milliseconds.

In one possible embodiment, if it is determined to pick up ambient sounds to detect the state of the headset, the headset may pick up an ambient sound signal at a frequency using the microphone in the unworn condition and store the picked up ambient sound signal until it is determined that the headset is worn. Wherein the certain frequency may be a predetermined frequency, such as collecting the ambient sound signal every 1 second, and storing the ambient sound signal until it is determined that the headset is worn.

Then, under the condition that the earphone is worn, the microphone is also used for collecting the environment sound signals, the collection intervals of the recently collected environment sound signals stored under the condition that the earphone is not worn and the environment sound signals collected under the condition that the earphone is worn are close, and it can be considered that the environment sounds in the environment are basically consistent or have small difference before and after the earphone is worn and belong to the same sound source, so that the state of the earphone can be determined based on the sound pressure difference of the same sound source before and after the earphone is worn.

In addition, considering that the collected ambient sound may not satisfy the requirement of detecting whether the earphone is worn in place in some environments, for example, in a quieter environment, the sound pressure of the collected ambient sound signal is low, which may result in an inaccurate state detection result of the earphone. Therefore, in order to further improve the accuracy of the state detection result of the headset (i.e. the result of detecting whether the headset is worn in place), it may be considered that, when the headset is in a non-quiet environment, the headset does not need to play a preset audio, but directly collects ambient sound to detect whether the headset is worn in place, so as to be beneficial to improving the accuracy of headset state detection based on an ambient sound signal.

Wherein, whether the current environment is a non-quiet environment or not can be determined by an environment sound signal of the current environment collected by a microphone in the earphone, such as by preset parameters (such as sound pressure, volume, etc.) of the environment sound signal. For example, the non-quiet environment refers to that preset parameters (such as sound pressure, volume, and the like) of an environment sound of the current environment meet preset requirements, for example, the preset requirements include that the sound pressure of the environment sound of the current environment is greater than at least one of a preset sound pressure value and the volume of the environment sound is greater than a preset volume value, and the preset sound pressure value and the preset volume value may be specifically set according to an actual application scenario. The embodiment of the disclosure collects the environmental sound to detect whether the earphone is worn in place under the condition that the earphone is in a non-quiet environment, thereby being beneficial to improving the accuracy of the detection result.

In other embodiments, taking as an example that the first sound signal and the second sound signal are both acquired by the microphone when the earphone plays a preset audio, please refer to fig. 4, where fig. 4 is another schematic flow chart of the method for detecting the wearing detection state of the earphone provided by the embodiment of the present disclosure, the method includes:

in step S301, an ambient sound signal is collected by using the microphone, and a current ambient type is determined based on a sound pressure corresponding to the ambient sound signal.

In step S302, a current state detection policy is determined based on the current environment type; the state detection strategy indicates a manner of processing the first and second sound signals.

In step S303, under a condition that the headset is not worn, playing preset audio using a speaker in the headset and acquiring a first sound signal using a microphone in the headset.

In step S304, under the condition that the headset is worn, a preset audio is played using a speaker in the headset and a second sound signal is collected using the microphone.

In step S305, determining a state of the earphone according to a difference between a sound pressure corresponding to the first sound signal in the state detection strategy and a sound pressure corresponding to the second sound signal in the state detection strategy, wherein the state of the earphone includes at least one of whether the earphone is worn in place and whether the earphone blocks the hole.

In some embodiments, the environment type includes a quiet type and a non-quiet type, and may be determined according to preset parameters (such as sound pressure, volume, etc.) of the environment tone signal of the current environment collected by the microphone. In one example, if the sound pressure of the environment sound signal is less than a preset sound pressure value and/or the volume of the current environment sound is less than a preset volume value, determining that the current environment is a quiet environment; and if the sound pressure of the environment sound signal is greater than or equal to a preset sound pressure value and/or the volume of the current environment sound is greater than or equal to a preset volume value, determining that the current environment is a non-quiet environment. It is understood that the specific magnitudes of the preset sound pressure value and the preset volume value may be specifically set according to an actual application scenario, and the embodiment does not limit this.

Wherein the state detection strategy refers to a strategy for obtaining the state of the earphone according to the first sound signal and the second sound signal, and the state detection strategy is different under different environment types. In one example, if the ambient noise is small in a quiet environment, for example, the ambient noise has a small influence on the sound pressure of the sound signal collected by the microphone of the earphone, and the first sound signal and the second sound signal may be used directly without being processed, and the earphone state detection may be performed according to the sound pressure difference between the first sound signal and the second sound signal. In another example, if the ambient noise is large in a non-quiet environment, for example, the sound pressure of the sound signal collected by the microphone of the earphone is greatly affected by the ambient noise, in order to ensure accurate detection of the earphone state, it is necessary to eliminate the influence of the ambient noise on the first sound signal and the second sound signal, and perform earphone state detection using the sound pressure difference between the first sound signal and the second sound signal after the influence of the ambient noise is eliminated.

Thus, the state detection strategy may comprise a first state detection strategy indicating that the first sound signal and the second sound signal are not processed in a quiet environment and a second state detection strategy indicating that the first sound signal and the second sound signal are compensated for using an ambient sound signal, respectively, in a non-quiet environment, enabling cancellation of the effects of ambient noise.

In some embodiments, if the current environment type is a quiet environment, determining to adopt a first state detection strategy, wherein in the first state detection strategy, the state of the headset is determined directly through the sound pressure difference between the collected first sound signal and the collected second sound signal without processing the first sound signal and the second sound signal; and/or determining to adopt a second state detection strategy if the current environment type is a non-quiet environment, wherein in the second state detection strategy, the environment sound signals are used for respectively compensating the first sound signals and the second sound signals, and the sound pressure difference between the compensated first sound signals and the compensated second sound signals is used for determining the state of the earphone. In the embodiment of the disclosure, different state detection strategies are adopted based on different environment types, so that the influence of environmental noise on the earphone state detection result is eliminated, and the earphone state detection accuracy is improved.

For example, the process of respectively compensating the first sound signal and the second sound signal by using the ambient sound signal may be: the earphone acquires a compensation signal with a phase opposite to that of the environment sound signal, then the compensation signal is used for respectively compensating the first sound signal and the second sound signal, and then environment sound components in the first sound signal and the second sound signal are offset from the compensation signal, so that the influence of the environment sound signal is eliminated, and the accuracy of earphone state detection is improved.

In order to further improve the accuracy of earphone state detection, considering that the environment sound signals of the earphone in the current environment may also be different before and after the earphone is worn, the environment sound signals may be collected before and after the earphone is worn, that is, if the current environment type is a non-quiet environment, under the condition that the earphone is not worn, the microphone is used to collect the first environment sound signal in the current environment, then the speaker in the earphone is controlled to play the preset audio, and the microphone in the earphone is used to collect the preset audio to obtain the first sound signal; under the condition that the earphone is worn, the microphone is used for collecting a second environment sound signal in the current environment, then the loudspeaker in the earphone is controlled to play preset audio, meanwhile, the microphone in the earphone is used for collecting the preset audio to obtain a second sound signal, then the first sound signal can be compensated by using a first compensation signal obtained based on the first environment sound signal, and the second sound signal can be compensated by using a second compensation signal obtained based on the second environment sound signal. In the embodiment of the disclosure, in consideration of the difference of the environmental sound signals of the earphone in the current environment before and after wearing, the first environmental sound signal and the second environmental sound signal are respectively collected before playing the preset audio, and are used for respectively compensating the first sound signal and the second sound signal, so that the influence of the environmental noise with the difference is effectively eliminated, two sound signals of the same sound source before and after wearing the earphone are obtained, and the accuracy of earphone state detection is further improved.

In some embodiments, to save computing resources, it may be considered that in a non-quiet environment, the first sound signal and the second sound signal are both acquired by the microphone when the earphone plays a preset audio; in a quiet environment, the first sound signal and the second sound signal are both environment sound signals, so that the acquired first sound signal and the acquired second sound signal can be directly used for detecting the state of the earphone, and the first sound signal and the second sound signal do not need to be additionally processed (such as compensation processing), thereby being beneficial to saving computing resources and improving the detection efficiency of the earphone state.

In some embodiments, after acquiring the first sound signal and the second sound signal, the earphone may determine an isolation degree of the earphone from sound according to a difference between a sound pressure corresponding to the first sound signal and a sound pressure corresponding to the second sound signal, and then determine whether the earphone is worn in place according to the isolation degree of the earphone from sound, wherein a higher isolation degree of the earphone from sound indicates a higher possibility that the earphone is worn in place; the earphone has low isolation from sound, indicating that the earphone may not be worn in place or that a plugged hole condition may occur. In this embodiment, the isolation of the earphone to sound has a strong correlation with the earphone state, so that accurate detection of the earphone state can be realized through the isolation of the earphone to sound.

In a possible implementation manner, in the process of determining the state of the earphone according to the isolation degree of the earphone to sound, if the isolation degree of the earphone to sound is within a first preset range, determining that the earphone blocks the hole; or if the isolation degree of the earphone to sound is higher than the first preset range and is within a second preset range, determining that the earphone is not worn in place or the earphone does not block the hole; or if the isolation degree of the earphone to sound is higher than the second preset range, determining that the earphone is worn in place. The first preset range is used for representing the reference isolation degree when the earphone blocks the hole, and the second preset range is used for representing the reference isolation degree when the earphone does not block the hole and/or the earphone is not worn in place. The embodiment realizes that the isolation of the earphone to sound is measured through different reference ranges corresponding to the earphone state, and the earphone state is accurately detected.

Wherein the maximum value in the first preset range is less than or equal to the minimum value in the second preset range. It is understood that the first preset range and the second preset range may be specifically set according to actual situations.

In one example, the minimum value in the first preset range may be set to 0 db, the maximum value may be set to a weaker sound pressure level that can be perceived by a user, for example, 10 db, and the minimum value in the second preset range is greater than or equal to the maximum value in the first preset range, for example, the minimum value in the second preset range is also set to 10 db. It may happen that the earphone is completely or mostly blocked if the isolation of the earphone from sound is within a first predetermined range, indicating that there is little difference between the first sound signal and the second sound signal. If the isolation of the earphone to sound is higher than the first preset range and within the second preset range, which indicates that the difference between the first sound signal and the second sound signal is large, a situation that the earphone does not block the hole or a small part of the hole blocks the hole may occur, or the earphone is not worn in place, or both of them may occur. If the isolation degree of the earphone to sound is higher than the second preset range, the earphone is determined to be worn in place, and the earphone can play audio according to the requirements of a user. In some embodiments, a difference between the sound pressure corresponding to the first sound signal and the sound pressure corresponding to the second sound signal and the isolation degree of the earphone from sound are in a positive correlation relationship, and the larger the difference is, the higher the isolation degree of the earphone from sound is, the more likely the earphone is worn in place is indicated. For example, the isolation of the earphone from sound may be a difference between a sound pressure corresponding to the first sound signal and a sound pressure corresponding to the second sound signal. For example, the isolation of the earphone with respect to sound may also be a product of a difference between a sound pressure corresponding to the first sound signal and a sound pressure corresponding to the second sound signal and a preset parameter.

In an exemplary embodiment, taking the isolation of the earphone from sound as a difference between the sound pressure corresponding to the first sound signal and the sound pressure corresponding to the second sound signal as an example, the earphone may determine the state of the earphone according to a difference between the sound pressure corresponding to the first sound signal and the sound pressure corresponding to the second sound signal and a difference between a first preset range and a second preset range. If the difference value is within a first preset range, determining that the earphone blocks the hole; if the difference value is higher than the first preset range and is within a second preset range, determining that the earphone is not worn in place or the earphone does not block the hole; and if the difference value is higher than the second preset range, determining that the earphone is worn in place. The embodiment of the disclosure realizes measuring the isolation of the earphone from sound through different reference ranges corresponding to the earphone state, and realizes accurate detection of the earphone state.

In order to improve the accuracy of detecting the state of the earphone, the first sound signal and the second sound signal are from different sound sources, and the first preset range and the second preset range corresponding to the first sound signal and the second sound signal are different. For example, the first sound signal and the second sound signal are both environment sound signals, and the first preset range and the second preset range corresponding to the first sound signal and the second sound signal are determined according to the sound pressure difference of the environment sound signals before and after the headset is worn in the historical time period and the sound quality condition corresponding to the sound pressure difference; for example, the first sound signal and the second sound signal are both acquired by the microphone when the earphone plays a preset audio, and the corresponding first preset range and the second preset range are determined according to sound pressure difference of preset audio acquired before and after the earphone is worn in a historical time period and corresponding sound quality conditions.

In step S508, an isolation degree of the earphone with respect to sound is determined according to a difference between a sound pressure corresponding to the first sound signal and a sound pressure corresponding to the second sound signal.

In step S509, it is determined whether the isolation of the earphone from sound is within a first preset range; if yes, go to step S510; if not, go to step S511.

In step S510, it is determined that the earphone blocks the hole.

In step S511, it is determined whether the isolation of the earphone from sound is higher than the first preset range and within a second preset range; if yes, go to step S512; if not, go to step S513.
