Detailed Description

Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The present embodiment provides a sound pickup 100, and as shown in fig. 1 to 3, the sound pickup 100 is configured to be mounted on a bone conduction sound transmission organ 200 in the oral cavity. The bone conduction sound transmission organ 200 may be a tooth or an alveolar bone, and the sound pickup 100 may be mounted on the bone conduction sound transmission organ 200 in a stress-coupled manner. The sound pick-up 100 comprises a detection module 1, and the detection and collection of the vibration signal of the bone conduction sound transmission organ 200 are realized through the detection module 1.

Compared with an air conduction microphone, the vibration of air reaches the microphone to complete conversion from mechanical energy to electric energy, and the sound pick-up 100 of the embodiment of the application directly collects vibration signals on the bone conduction sound transmission organ 200 arranged in the oral cavity. When a person speaks, the vocal cord vibrates to drive the skull to vibrate, the skull vibrates to drive the bone conduction sound transmission organs 200 in the oral cavities such as teeth or alveolar bones to vibrate, and the bone conduction vibration energy generated on the skull is far greater than the air conduction vibration energy, so that the detection module 1 is adopted to collect vibration signals of the teeth or the alveolar bones, the signals collected by the common air conduction microphone are better than those collected by the percutaneous bone conduction microphone, and the pickup 100 has the technical effect of high-definition pickup.

In addition, a detection module 1 for detecting the vibration signal of bone conduction transaudient organ 200 is insensitive to air vibration, only is sensitive to solid vibration signal, so need not to design air conduction access structure for the waterproof design of adapter 100 easily realizes, and to gathering vibration bone conduction speech signal unique advantage under the high noise environment, can gather self bone conduction high definition sound signal under the high noise environment.

In some exemplary embodiments, the detection module 1 comprises at least one acceleration sensor. An acceleration sensor is a sensor capable of measuring acceleration, and generally comprises a mass, a damper, an elastic element, a sensing element, an adaptive circuit and the like. Common acceleration sensors include capacitive, inductive, strain, piezoresistive, piezoelectric, etc. depending on the sensor sensing element, and the type of sensor is not limited herein.

Because the acceleration sensor is only sensitive to the vibration signal, the structural design of the air conduction passage is not needed. Since the acceleration sensor does not require the structural design of the air guide passage, it is particularly easy to design the microphone 100 in a waterproof manner, simplifying the design, and reducing the manufacturing cost. The acceleration sensor is sensitive to solid vibration and insensitive to air vibration, so that the acceleration sensor has unique advantages for collecting vibration bone conduction voice signals in a high-noise environment.

Wherein, set up at least one acceleration sensor in order to detect along the vibration in at least one direction in first direction, second direction and the third direction, can only detect the ascending vibration signal of certain direction, also can be two directions, or all detect the vibration of three direction, improve the flexibility of use of adapter 100. The first direction, the second direction and the third direction are mutually perpendicular in pairs, that is, the three directions of the first direction, the second direction and the third direction jointly form a three-dimensional coordinate system in a space, as shown in fig. 1, the first direction can be set to be an X direction (a direction facing a human body, namely, a front-back direction), the second direction can be set to be a Y direction (a width direction of the human body, namely, a left-right direction), and the third direction can be set to be a Z direction (a height direction of the human body, namely, an up-down direction).

Such as: at least one acceleration sensor can realize the detection of the vibration along the first direction, the second direction and the third direction, and then the vibration signals of the three directions are synthesized, so that the sound can be well reproduced, and certain clarity is achieved.

In some exemplary embodiments, to achieve the above-mentioned detection of vibration signals in different directions, the acceleration sensor may be a single-axis acceleration sensor, a two-axis acceleration sensor, or a three-axis acceleration sensor, or a combination of acceleration sensors, and a plurality of acceleration sensors may be mounted on the bone conduction and sound transmission organ 200 in a stacked manner. Unipolar acceleration sensor and triaxial acceleration sensor respectively have the advantage, and unipolar acceleration sensor's directive property is stronger, and triaxial acceleration sensor can superpose all vibration signal and arrange in order to reappear effectually, tone quality nature, the equilibrium is better, the higher signal acquisition of fidelity.

In some exemplary embodiments, the detection module 1 includes a plurality of acceleration sensors with different bandwidths for detecting vibrations in the same direction (which may be one direction or two directions or three directions).

For example, for the acceleration sensor with two different bandwidths (which may be a single-axis acceleration sensor) along a first direction (e.g., the X direction), low-frequency and medium-high-frequency signals, or medium-low-frequency and high-frequency signals, along the X direction, are respectively acquired. The cooperation of the acceleration sensors with different bandwidths realizes full-frequency detection of signals in the set direction, improves the detection bandwidth and also improves the detection accuracy. The detection frequencies of a plurality of bandwidths can be overlapped on a certain frequency value, so that frequency leakage is avoided.

For example, for the acceleration sensors (which may be single-axis acceleration sensors) with two different bandwidths in each of the first direction (e.g., X direction) and the second direction (e.g., Y direction), the low-frequency and medium-high-frequency signals in the X direction and the low-frequency and medium-high-frequency signals in the Y direction are respectively collected, or the medium-low-frequency and high-frequency signals in the X direction and the medium-low-frequency and high-frequency signals in the Y direction are respectively collected. The operating frequency bands of the acceleration sensors that collect the low-frequency or medium-low-frequency signals in the two directions may be set to be the same or different, and the operating frequency bands of the acceleration sensors that collect the high-frequency or medium-high-frequency signals in the two directions may be set to be the same or different.

Alternatively, for the first direction (for example, the X direction) and the second direction (for example, the Y direction), two acceleration sensors (for example, two-axis acceleration sensors) with different bandwidths may be used to collect the low-frequency signals along the X direction and the Y direction and the medium-high frequency signals along the X direction and the Y direction, or the medium-low frequency signals along the X direction and the Y direction and the high-frequency signals along the X direction and the Y direction, respectively.

It should be understood that the detection module may use other vibration sensors capable of detecting vibration, such as piezoelectric sensors, besides the acceleration sensor to acquire the vibration signal of the tooth or alveolar bone.

In some exemplary embodiments, as shown in fig. 1, the sound pickup 100 further includes a housing 2, a circuit board (not shown), and a power module (not shown). The detection module 1, the power supply module and the circuit board are all arranged in the shell 2, so that the integrity of the sound pick-up 100 can be improved, and the sound pick-up 100 is convenient to install or store.

The circuit board is electrically connected with the detection module 1 and controls the work of the detection module 1, and the power supply module is used for supplying power to the circuit board and the detection module 1.

In some exemplary embodiments, as shown in fig. 1, the pickup 100 further includes a fixing cover 3 for fixing the housing 2 to the fixing cover 3, and the fixing cover 3 may be made of elastic plastic material for fixing the housing 2 to an inner side wall or an outer side wall of the fixing cover 3. As shown in fig. 1, the fixing sleeve 3 is disposed on the teeth in a set, that is, the fixing sleeve 3 and the teeth form a similar concave-convex insertion fit, so that the sound pickup 100 is firmly installed and has a beautiful appearance.

In other exemplary embodiments, as shown in fig. 2a and 2b, the sound pickup 100 further includes a clip 4, and the housing 2 is fixed to the clip 4. Wherein, the clamping member 4 can be configured as a metal or nonmetal elastic clamping member (for example, the clamping member 4 can be a steel pipe structure), and the clamping member 4 is disposed around the tooth, that is, the clamping member 4 is clamped on the tooth, so that the mounting stability of the sound pick-up 100 can be improved. Wherein the housing 2 may be adhered to the holder 4 by the adhesive portion 5, or otherwise fixed to the holder 4.

In other exemplary embodiments, as shown in fig. 3, an adhesive part 5 is provided on the shell 2, and one side of the adhesive part 5 close to the teeth is matched with the outer shape of the teeth, so as to facilitate the adhesive fixation of the teeth and improve the installation firmness

In another embodiment of the present application, as shown in fig. 4, a communication device 300 is provided, which includes a signal receiving module 6, a control module 7 and a communication module 8, wherein the signal receiving module 6 and the communication module 8 are electrically connected to the control module 7, and the control module 7 can control the operation of the signal receiving module 6 and the communication module 8. The signal receiving module 6 is configured to receive the signal of the sound pickup 100, and the communication module 8 is configured to transmit the signal of the signal receiving module 6 to the outside, so that effective transmission of information can be realized.

The communication device 300 can receive the vibration signal detected by the detection module 1 of the sound pickup 100, and transmit the signal of the signal receiving module 6 to the outside through the communication module 8, at this time, the signal-to-noise ratio of the transmitted sound signal is large, and the interference of noise is reduced.

In some exemplary embodiments, the communication device 300 may be configured as an intercom, and the communication module 8 is configured to transmit and receive signals, so that two-way effective transmission of information can be realized.

In the traditional interphone, a microphone is required to collect a sound signal conducted by air vibration, the noise interference in the collected signal is serious, and an acceleration sensor in the sound pick-up 100 is sensitive to a solid vibration signal and is insensitive to noise of ambient air disturbance, so that a bone conduction signal of a speaker can be collected in a high-noise environment, and the traditional interphone has excellent cost performance.

In some exemplary embodiments, the control module 7 is configured to enable the intercom to be in the transmitting state when the signal received by the signal receiving module 6 (i.e. the vibration signal detected by the detection module 1 of the sound pickup 100) is consistent with the preset transmitting switch signal, and to enable the intercom to be in the receiving state when the signal received by the signal receiving module 6 is inconsistent with the preset transmitting switch signal.

An intercom typically has two states, a transmit state in which a user can speak and send his/her own words to others, and a receive state in which a user can listen to the other's speech. The existing interphone is generally provided with a talk button, and the interphone is in a transmitting state after the talk button is pressed; and releasing the talk button, and enabling the interphone to be in a receiving state.

According to the interphone, the emitting switch signal is preset in the control module 7, when a user emits specific sound, for example, regular sound is emitted by a tongue (is clicked) or teeth collide, the sound signal can be detected by the detection module 1 of the sound pickup 100 and transmitted to the interphone, the signal can be compared with the preset emitting switch signal by the control module 7 of the interphone, when the sound signal and the preset emitting switch signal are consistent, the interphone is controlled to be in an emitting state by the control module 7, and when the sound signal and the preset emitting switch signal are inconsistent, the interphone is controlled to be in a receiving state by the control module 7.

The interphone is controlled to be in a transmitting state or a receiving state through the sound signal, so that the interphone is convenient to use by people (or special scenes) who do not have hands or are inconvenient to control the interphone by hands, and the use convenience and the application range of the communication device 300 are improved.

It should be understood that the communication device 300 may also be other devices outside of an intercom, such as: cell phones, headsets, etc.
