Based on the hardware structure, the embodiment of the earphone state detection method is provided.

An embodiment of the present invention provides a method for detecting an earphone status, and referring to fig. 2, fig. 2 is a schematic flow diagram of a first embodiment of a method for detecting an earphone status according to the present invention.

In a first embodiment, the headphone state detection method includes the steps of:

step S10: and acquiring distance information between the earphone and the target detection point.

It should be noted that the execution main body of this embodiment may be an earphone status detection device, and may also be other devices that can achieve the same or similar functions.

It should be understood that the distance information between the earphone and the target detection point may be acquired by a distance sensor, where the distance sensor may be disposed in the earphone, the earphone may be a TWS earphone, and the target detection point may be a body part of a wearer of the earphone, such as an ear, which is not limited in this embodiment. The distance sensor may be an infrared distance sensor, an optical distance sensor, an ultrasonic distance sensor, or the like, which is not limited in this embodiment, and the infrared distance sensor may be used as an example in a specific implementation process, so that the distance sensor emits an infrared light source, and determines whether to be close to the target detection point or far from the target detection point by receiving the reflection intensity, so as to sense the distance information between the earphone and the target detection point.

Step S20: and if the distance information is smaller than a preset distance threshold value, acquiring the direction information of the earphone.

It is understood that the preset distance threshold can be set by those skilled in the art, and the present embodiment is not limited thereto, by judging whether the distance information between the earphone and the earphone wearer is smaller than a preset distance threshold value or not, if the distance information between the earphone and the earphone wearer is smaller than the preset distance threshold value, the acceleration sensor is started, in the specific implementation process, the acceleration sensor can be a three-axis acceleration sensor, the acceleration sensor is used for detecting the movement data of the earphone, the movement state of the earphone can be determined according to the movement data, wherein the motion state of the earphone comprises a static state and a motion state, if the motion data meets the static state condition, the position information of the earphone is determined through a preset coordinate system, if the motion data meets the motion state condition, the earphone is probably in a wearing state, the distance needs to be determined again, so the step of obtaining the distance information between the earphone and the target detection point can be executed again.

It should be noted that the acceleration sensor may be disposed in the earphone, which is not limited in this embodiment, so that the acceleration sensor and the distance sensor may be directly initialized when the earphone is taken out of the box. The orientation information may be coordinate orientation information of the headset wearer in a coordinate system established centered on the acceleration sensor.

Furthermore, if the distance information between the earphone and the earphone wearer is greater than or equal to the preset distance information, it indicates that the earphone is not in the in-ear state, and therefore the operation of acquiring the distance information between the earphone and the target detection point can be executed again.

Step S30: and determining the use state of the earphone according to the direction information of the earphone.

It should be understood that the usage state of the headset includes an in-ear state and an out-of-ear state, the horizontal axis coordinate orientation information, the vertical axis coordinate orientation information and the vertical axis coordinate orientation information of the orientation information can be acquired in the specific implementation process, and the usage state of the headset can be confirmed by detecting whether the horizontal axis coordinate orientation information, the vertical axis coordinate orientation information and the vertical axis coordinate orientation information of the orientation information are within a judgment range debugged in advance.

It should be noted that, since the wearer may be in an upright or lying position when the earphone is inserted into the ear, it is necessary to consider that the earphone wearer has an upright position and a lying position in the in-ear state, and different determination conditions are included for the in-ear state in the upright position and the in-ear state in the lying position, and therefore it is possible to determine whether the in-ear state based on the upright position and the in-ear state based on the lying position are within the corresponding pre-set determination range, and it is possible to more accurately confirm that the earphone wearer is in the in-ear state in the upright position and the in-ear state in the lying position.

The embodiment acquires the distance information between the earphone and the target detection point by the distance sensor; when the distance information is smaller than a preset distance threshold value, starting an acceleration sensor, detecting motion data of the earphone through the acceleration sensor, and if the earphone is in a static state, acquiring azimuth information of the earphone; and determining whether the position information of the earphone is in a preset judgment range or not according to the position information of the earphone, and if the position information of the earphone is in the preset judgment range, determining the use state of the earphone. After the distance between the earphone and the target detection object is judged to be within the preset distance threshold value, the direction information of the earphone is determined, and finally the comprehensive judgment of the in-and-out-of-ear state is carried out in a direction information detection mode, so that the accuracy of earphone state detection can be improved.

In an embodiment, referring to fig. 3, fig. 3 is a flowchart illustrating a method for detecting a state of an earphone according to a second embodiment of the present invention.

Based on the first embodiment, in step S20, the method for detecting the earphone status in this embodiment includes:

step S201, if the distance information is smaller than a preset distance threshold, obtaining motion data of the earphone.

It should be noted that the motion data may be acceleration data of the headset acquired by the acceleration sensor within a preset time period, where the preset time period may be set according to an acquisition requirement, and may be 0.5s in a specific implementation process, and when the distance information is smaller than a preset distance threshold, it is stated that the headset is closer to a headset wearer, and therefore, the acceleration sensor may be turned on, and the headset is determined to be in a motion state or a stationary state through a change condition of the acceleration data acquired by the acceleration sensor.

Further, after step S201 is implemented, the method further includes:

if the motion data meets the motion state condition, the step S10 is executed again, where the motion state condition is a state where the change value of the motion data is outside the preset interval within the preset time period.

It should be understood that, if a state in which a change value of the jerk data within a preset time period collected by the acceleration sensor is outside a preset interval indicates that the headset is in a motion state, where the change value of the jerk data may be a difference value between a maximum acceleration value and a minimum acceleration value in the jerk data, and the preset interval may be set by a person skilled in the art.

Step S202, if the motion data meets a static state condition, determining the direction information of the earphone, wherein the motion state condition is that the motion data is in a changing state within a preset time period.

It can be understood that, if the variation value of the motion data acquired by the acceleration sensor within the preset time period is outside the preset interval, it indicates that the headset is in a static state, and therefore the position information of the headset can be determined through the preset coordinate system.

Further, step S202 includes:

and if the motion data meet the static state condition, determining the azimuth information of the earphone according to a preset coordinate system.

It should be noted that the preset coordinate system may be a spatial coordinate system established by taking the position of the acceleration sensor as a center, which is not limited in this embodiment, if the motion data satisfies the condition that the earphone is in a stationary state, calibration and debugging of coordinate axes of the acceleration sensor are performed in advance according to the position and the assembling direction of the acceleration sensor in the earphone, and X, Y and three coordinate axes Z are preset, so as to determine the direction of the coordinate system of the acceleration sensor, where the direction of the Z axis is the direction of the rod body of the earphone, the direction of the X axis is the direction perpendicular to the plane where the sound opening is located at the earphone, and the direction of the Y axis is the direction perpendicular to both the X axis and the Z axis.

It is understood that the orientation information is determined by 6D direction identification according to the coordinate system direction and the motion data, and this embodiment does not limit this, wherein the orientation information includes horizontal axis coordinate orientation information, vertical axis coordinate orientation information, and vertical axis coordinate orientation information.

The embodiment acquires the distance information between the earphone and the target detection point by the distance sensor; if the distance information is smaller than a preset distance threshold value, acquiring the motion data of the earphone, wherein the motion data meets a motion state condition, re-executing the step of acquiring the distance information between the earphone and a target detection point, and if the motion data meets a static state condition, determining the azimuth information of the earphone according to a preset coordinate system; therefore, whether the coordinate and the azimuth information of the azimuth information are in the preset judgment range or not is determined according to the coordinate and the azimuth information of the azimuth information, and if the coordinate and the azimuth information are in the preset judgment range, the use state of the earphone can be determined. After the distance between the earphone and the target detection object is judged to be within the preset distance threshold value, the direction information of the earphone is determined, and finally the comprehensive judgment of the in-and-out-of-ear state is carried out through the direction information, so that the efficiency of earphone state detection accuracy is further improved.

In an embodiment, referring to fig. 4, fig. 4 is a flowchart illustrating a method for detecting a state of an earphone according to a third embodiment of the present invention.

Based on the above embodiment of detecting the earphone status, the step S30 includes:

step S301: and acquiring the horizontal axis coordinate orientation information, the vertical axis coordinate orientation information and the vertical axis coordinate orientation information of the orientation information.

It can be understood that the horizontal axis coordinate orientation information, the vertical axis coordinate orientation information, and the vertical axis coordinate orientation information may be coordinate values of X, Y and Z axes of the acquisition headset recognized by the acceleration sensor through the 6D direction, and in a specific implementation process, g (x) may be used to represent the horizontal axis coordinate orientation information, g (y) may be used to represent the vertical axis coordinate orientation information, and g (Z) may be used to represent the vertical axis coordinate orientation information, which is not limited in this embodiment.

It is to be understood that, when it is first determined whether the abscissa orientation information is larger than the first coordinate orientation information or smaller than the second coordinate orientation information, it is further determined whether the ordinate orientation information is g (z) larger than the third coordinate orientation information c or smaller than the fourth coordinate orientation information d by determining whether the abscissa orientation information is larger than the first coordinate orientation information or smaller than the second coordinate orientation information, i.e., g (x) > a or g (x) < b.

It is to be understood that by determining whether the vertical axis coordinate orientation information is larger than the third coordinate orientation information or smaller than the fourth coordinate orientation information, i.e., g (z) > c or g (z) < d, it is further determined whether the vertical axis coordinate orientation information g (y) is larger than the fifth coordinate orientation information e and smaller than the sixth coordinate orientation information f.

And if the longitudinal axis coordinate position information is greater than the fifth coordinate position information and less than the sixth coordinate position information, determining the use state of the earphone.

It should be understood that by judging that if the vertical axis coordinate orientation information is larger than the fifth coordinate orientation information and smaller than the sixth coordinate orientation information, i.e., e < g (y) < f, it is possible to determine that the earphone is in the use state and that the use state is in the in-ear state, and considering that the wearer has the upright posture state and the lying posture state, it is possible to further determine that the earphone is in the in-ear state in the upright posture state by the above judgment, and if the above judgment condition is not satisfied, it is indicated that the earphone is in the not-in-ear state, and therefore, it is necessary to perform the step of acquiring the distance information between the earphone and the target detection point in a reset manner.

Step S303: and if the longitudinal axis coordinate position information is greater than the first coordinate position information or less than the second coordinate position information, determining the use state of the earphone according to the transverse axis coordinate position information and the vertical axis coordinate position information.

And if the vertical axis coordinate position information is greater than the third coordinate position information or less than the fourth coordinate position information, judging whether the horizontal axis coordinate position information is greater than the fifth coordinate position information and less than the sixth coordinate position information.

It should be understood that the distance information between the earphone and the target detection point may be acquired by a distance sensor, where the distance sensor may be disposed in the earphone, the earphone may be a TWS earphone, and the target detection point may be a body part of a wearer of the earphone, such as an ear, which is not limited in this embodiment. The distance sensor may be an infrared distance sensor, an optical distance sensor, an ultrasonic distance sensor, or the like, which is not limited in this embodiment, and the infrared distance sensor may be used as an example in a specific implementation process, so that the distance sensor emits an infrared light source, and determines whether to be close to the target detection point or far from the target detection point by receiving the reflection intensity, so as to sense the distance information between the earphone and the target detection point.

It should be noted that the preset distance threshold may be set by a person skilled in the art, which is not limited in this embodiment, by determining whether the distance information between the earphone and the earphone wearer is within the preset distance threshold, if the distance information between the earphone and the earphone wearer is greater than or equal to the preset distance information, it is indicated that the earphone is in a non-in-ear state at this time, and therefore, the operation of obtaining the distance information between the earphone and the target detection point may be performed again.

And the direction confirmation module 20 is configured to acquire the direction information of the headset if the distance information is smaller than a preset distance threshold.

It can be understood that the preset distance threshold may be set by a person skilled in the art, which is not limited in this embodiment, by determining whether the distance information between the earphone and the earphone wearer is smaller than the preset distance threshold, and if the distance information between the earphone and the earphone wearer is smaller than the preset distance threshold, turning on the acceleration sensor, in a specific implementation process, the acceleration sensor may be a three-axis acceleration sensor, detecting the motion data of the earphone through the acceleration sensor, and determining the motion state of the earphone according to the motion data, where the motion state of the earphone includes a static state and a motion state, if the motion data satisfies the static state condition, the orientation information of the earphone may be determined through a preset coordinate system, and if the motion data satisfies the motion state condition, it is indicated that the earphone is probably in a wearing state, the distance needs to be determined again, the step of obtaining distance information of the headset from the target detection point can be re-performed.

It should be noted that the acceleration sensor may be disposed in the earphone, which is not limited in this embodiment, so that the acceleration sensor and the distance sensor may be directly initialized when the earphone is taken out of the box. The orientation information may be coordinate orientation information of the headset wearer in a coordinate system established centered on the acceleration sensor.

Furthermore, if the distance information between the earphone and the earphone wearer is greater than or equal to the preset distance information, it indicates that the earphone is not in the in-ear state, and therefore the operation of acquiring the distance information between the earphone and the target detection point can be executed again.

And the state confirmation module 30 is used for determining the use state of the earphone according to the direction information of the earphone.

It should be understood that the usage state of the headset includes an in-ear state and an out-of-ear state, the horizontal axis coordinate orientation information, the vertical axis coordinate orientation information and the vertical axis coordinate orientation information of the orientation information can be acquired in the specific implementation process, and the usage state of the headset can be confirmed by detecting whether the horizontal axis coordinate orientation information, the vertical axis coordinate orientation information and the vertical axis coordinate orientation information of the orientation information are within a judgment range debugged in advance.

It should be noted that, since the wearer may be in an upright or lying position when the earphone is inserted into the ear, it is necessary to consider that the earphone wearer has an upright position and a lying position in the in-ear state, and different determination conditions are included for the in-ear state in the upright position and the in-ear state in the lying position, and therefore it is possible to determine whether the in-ear state based on the upright position and the in-ear state based on the lying position are within the corresponding pre-set determination range, and it is possible to more accurately confirm that the earphone wearer is in the in-ear state in the upright position and the in-ear state in the lying position.

The embodiment acquires the distance information between the earphone and the target detection point by the distance sensor; if the distance information is smaller than a preset distance threshold value, acquiring the motion data of the earphone, wherein the motion data meets a motion state condition, re-executing the step of acquiring the distance information between the earphone and a target detection point, and if the motion data meets a static state condition, determining the orientation information of the earphone by direction identification according to a coordinate system established by taking the position of an acceleration sensor as a center; therefore, whether the coordinate and the azimuth information of the azimuth information are in the preset judgment range or not is determined according to the coordinate and the azimuth information of the azimuth information, and if the coordinate and the azimuth information are in the preset judgment range, the use state of the earphone can be determined. After the distance between the earphone and the target detection object is judged to be within the preset distance threshold value, the direction information of the earphone is determined, and finally the comprehensive judgment of the in-and-out-of-ear state is carried out through the direction information, so that the efficiency of earphone state detection accuracy is further improved.
