[0032] The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily.

[0033] The present application embodiment provides a hearing aid intraoral device 100, such as Figure 1-Figure 3 As shown, the hearing aid intraoral device 100 is configured to be installed on a bone conduction sound transmitting organ 200 in the oral cavity. The bone conduction sound transmitting organ 200 may be a tooth or an alveolar bone, and the hearing aid intraoral device 100 may be installed on the bone conduction sound transmitting organ 200 in a stress coupling manner.

[0034] The hearing aid intraoral device 100 is configured to include a vibration device 1 and a detection device 2. The vibration device 1 is configured to drive the bone conduction sound transmission organ 200 to vibrate, and the detection device 2 is configured to detect the vibration signal of the bone conduction sound transmission organ 200.

[0035] The hearing aid intraoral device 100 can be used in conjunction with the hearing aid external device. The hearing aid external device can collect external sound signals and transmit the sound signals to the vibration device 1. The vibration device 1 can drive the bone conduction sound transmission organ 200 to vibrate, thereby driving the skull to vibrate, so as to achieve bone conduction transmission of the sound signal.

[0036] The vibration of the skull may be collected by the external hearing aid device again. If the signal is fixedly transmitted through the vibration device 1, it may cause howling. At this time, the detection device 2 can detect the vibration signal of the bone conduction sound transmission organ 200 and transmit it to the external hearing aid device. The external hearing aid device can feedback suppress the sound signal collected by the external hearing aid device based on the detection signal of the detection device 2 to prevent howling.

[0037] Compared with an air conduction microphone, which converts mechanical energy into electrical energy through the vibration of the air reaching the microphone, the intra-oral hearing aid 100 of the embodiment of the present application directly collects the vibration signal on the bone conduction sound organ 200 set in the oral cavity through a detection device, and can collect its own bone conduction high-definition sound signal in a high-noise environment.

[0038] In addition, the detection device 2 for detecting the vibration signal of the bone conduction sound transmitting organ 200 is not sensitive to air vibration, but only to solid vibration signals, so there is no need to design an air conduction path structure, making the waterproof design of the hearing aid intra-oral device 100 easy to implement, and has unique advantages in collecting vibration bone conduction voice signals in a high-noise environment, and can collect its own bone conduction high-definition sound signals in a high-noise environment.

[0039] In some exemplary embodiments, the detection device 2 is configured to include at least one acceleration sensor. An acceleration sensor is a sensor capable of measuring acceleration, and is generally composed of a mass block, a damper, an elastic element, a sensitive element, and an adaptive circuit. Depending on the difference in the sensor's sensitive element, common acceleration sensors include capacitive, inductive, strain, piezoresistive, piezoelectric, etc., and the type of sensor is not limited here.

[0040] Since the acceleration sensor is only sensitive to vibration signals, there is no need for air conduction pathway structure design. Since the acceleration sensor does not require air conduction pathway structure design, the waterproof design of the hearing aid intraoral device 100 is particularly easy, which can simplify the design and reduce the manufacturing cost. The acceleration sensor is sensitive to solid vibration and insensitive to air vibration, so it has a unique advantage in collecting vibration bone conduction voice signals in a high noise environment.

[0041] At least one acceleration sensor is provided to detect vibration in at least one direction of the first direction, the second direction and the third direction, that is, the vibration signal in only one direction, or in two directions, or the vibration in all three directions can be detected, so as to improve the use flexibility of the hearing aid intra-oral device 100. The first direction, the second direction and the third direction are mutually perpendicular, that is, the first direction, the second direction and the third direction together form a three-dimensional coordinate system in space, such as Figure 1As shown, the first direction can be set to the X direction (the direction facing the human body, i.e., the front-to-back direction), the second direction can be set to the Y direction (the width direction of the human body, i.e., the left-right direction), and the third direction can be set to the Z direction (the height direction of the human body, i.e., the up-down direction). Of course, the first direction, the second direction, and the third direction are not limited to the above.

[0042] For example, at least one acceleration sensor can detect vibrations in three directions: a first direction, a second direction, and a third direction. Then, the vibration signals in the three directions are synthesized to achieve better sound reproduction with a certain clarity.

[0043] In some exemplary embodiments, in order to realize the above detection of vibration signals in different directions, the acceleration sensor can be set as a single-axis acceleration sensor, a two-axis acceleration sensor or a three-axis acceleration sensor, or a combination of several acceleration sensors, and multiple acceleration sensors can be installed on the bone conduction sound transmission organ 200 in a superimposed manner. Single-axis acceleration sensors and three-axis acceleration sensors each have their own advantages. Single-axis acceleration sensors have stronger directivity, while three-axis acceleration sensors can superimpose and organize all vibration signals to reproduce good effects, natural sound quality, good balance, and high fidelity signal acquisition.

[0044] In some exemplary embodiments, the detection device 2 may also be configured to include a plurality of acceleration sensors with different bandwidths for detecting vibrations in the same direction (which may be one direction, two directions, or three directions).

[0045] For example, along the first direction (such as the X direction), two acceleration sensors with different bandwidths (which may be single-axis acceleration sensors) are used to collect low-frequency and medium-high frequency signals, or medium-low frequency and high frequency signals, respectively. The coordination of the above-mentioned 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 multiple bandwidths can also be set to have a certain frequency value overlap to avoid frequency leakage.

[0046] For example, for the first direction (such as the X direction) and the second direction (such as the Y direction), two acceleration sensors with different bandwidths (which may be single-axis acceleration sensors) are used in each direction to respectively collect low-frequency and medium-high frequency signals along the X direction, and low-frequency and medium-high frequency signals along the Y direction, or respectively collect medium-low frequency and high frequency signals along the X direction, and medium-low frequency and high frequency signals along the Y direction. The working frequency bands of the acceleration sensors that collect low-frequency or medium-low frequency signals in the two directions can be set to be the same or different, and the working frequency bands of the acceleration sensors that collect high-frequency or medium-high frequency signals in the two directions can be set to be the same or different.

[0047] Alternatively, for the first direction (such as the X direction) and the second direction (such as the Y direction), two acceleration sensors with different bandwidths (which may be two-axis acceleration sensors) can be used to respectively collect low-frequency signals along the X and Y directions, and medium- and high-frequency signals along the X and Y directions, or medium- and low-frequency signals along the X and Y directions, and high-frequency signals along the X and Y directions.

[0048] It should be understood that the detection device 2 can use not only acceleration sensors to collect vibration signals of teeth or alveolar bones, but also other vibration sensors that can detect vibrations, such as piezoelectric sensors.

[0049] Since piezoelectric vibrators have many advantages such as low energy consumption, no electromagnetic radiation, and easy miniaturization, in some exemplary embodiments, the vibration device 1 can be configured to include a piezoelectric vibrator. In addition, the cross-sectional shape of the piezoelectric vibrator can be set to be rectangular or circular.

[0050] In some exemplary embodiments, the hearing aid intra-oral device 100 is further configured to include a power supply device (not shown in the figure) and a circuit board (not shown in the figure). The vibration device 1 and the detection device 2 are both configured to be electrically connected to the circuit board, the power supply device is configured to supply power to the vibration device 1 and the detection device 2, and the power supply device, the circuit board and the detection device 2 are assembled and fixed.

[0051] The bone conduction sound transmitting organ 200 can be set as a tooth, the power supply device, the circuit board and the detection device 2 are set to be installed on one side of the tooth (such as the lingual side close to the tongue side), and the vibration device 1 is set to be installed on the other side of the tooth (such as the buccal side close to the cheek side).

[0052] It should be understood that the power supply device, the circuit board and the detection device 2, and the vibration device 1 can be arranged on opposite sides of the tooth, or on adjacent sides of the tooth, or on the same side of the tooth, etc.

[0053] In some exemplary embodiments, the hearing aid intraoral device 100 may also be configured to include a fixing sleeve 3. The vibration device 1 and the detection device 2 are both configured to be fixed on the fixing sleeve 3. The fixing sleeve 3 may be made of an elastic plastic material, and the vibration device 1 and the detection device 2 may be fixed on the inner wall or the outer wall of the fixing sleeve 3. Figure 1 As shown, the fixing sleeve 3 is arranged to be mounted on at least one tooth (such as one tooth or two teeth), that is, the fixing sleeve 3 and the tooth form a plug-in fit similar to a concave and convex form, so that the hearing aid intra-oral device 100 is firmly installed and has a more beautiful appearance; the vibration device 1 and the detection device 2 are respectively fixed on both sides of the fixing sleeve 3.

[0054] The fixing sleeve 3 is manufactured to have a shrinkage ratio so that when the fixing sleeve 3 is sleeved on the tooth, the fixing sleeve 3 can be firmly clamped on the tooth. The size of the fixing sleeve 3 can be slightly smaller than the size of the sleeved tooth so as to generate a firm interference fit between the fixing sleeve 3 and at least two surfaces of at least one tooth.

[0055] In some other exemplary embodiments, Figure 3 As shown, the hearing aid intra-oral device 100 also includes a clamping member 4, and the vibration device 1 and the detection device 2 are both configured to be fixed to the clamping member 4. The clamping member 4 can be configured as a metal or non-metal elastic clamping member (such as the clamping member 4 can be a steel pipe structure), so that the clamping member 4 can be elastically deformed. When the clamping member 4 is clamped on at least one tooth (such as one tooth or two teeth), the clamping member 4 can be deformed and have an interference fit with at least two surfaces of at least one tooth, so that the clamping member 4 is firmly clamped on at least one tooth, which can improve the stability of the installation of the hearing aid intra-oral device 100. When the clamping member 4 is clamped on at least one tooth, the clamping member 4 can surround at least one tooth.

[0056] The vibration device 1 and the detection device 2 can be bonded to the two sides of the clamping member 4 through the bonding portion 5, or fixed to the clamping member 4 through other methods.

[0057] The vibration device 1 and the detection device 2 can be fixed on the outside of the clamp 4 (i.e., the side away from the teeth), so that the vibration device 1 can drive the teeth to vibrate through the clamp 4, and the detection device 2 can detect the vibration transmitted from the teeth to the clamp 4. Alternatively, the vibration device 1 and the detection device 2 can be fixed on the inside of the clamp 4 (i.e., fixed between the clamp 4 and the teeth), so that the vibration device 1 can directly drive the teeth to vibrate or drive the teeth to vibrate through the clamp 4, and the detection device 2 can directly detect the vibration of the teeth or detect the vibration transmitted from the teeth to the clamp 4.

[0058] Or, if Figure 2 As shown, the vibration device 1 and the detection device 2 are configured to be directly bonded to the bone conduction sound transmitting organ 200, that is, a bonding portion 5 is provided on the vibration device 1 and the detection device 2, and the vibration device 1 and the detection device 2 are fixed on both sides of a tooth (such as one tooth or two teeth) through the bonding portion 5, and the side of the bonding portion 5 close to the tooth is matched with the outer surface of the tooth to improve the firmness of the installation.

[0059] As mentioned above, the various installation methods of the hearing aid intra-oral device 100 can increase the diversity of the product and thus meet the usage habits and needs of different users.

[0060] In some exemplary embodiments, the vibration device 1 is configured to transmit vibration to at least one tooth, the detection device 2 is configured to detect the vibration signal of at least one tooth, and the vibration of the vibration device 1 and the detection of the detection device 2 are performed synchronously, that is, the vibration device 1 and the detection device 2 are configured to synchronously transmit vibration to the surface of at least one tooth and detect the vibration signal of at least one tooth.

[0061] The tooth to which the vibration device 1 transmits vibration and the tooth to which the detection device 2 detects vibration can be the same tooth, such as: the vibration device 1 transmits vibration to one or two teeth, and the detection device 2 synchronously detects the vibration signals of the one or two teeth. Alternatively, the tooth to which the vibration device 1 transmits vibration and the tooth to which the detection device 2 detects vibration can be different teeth, such as: the vibration device 1 transmits vibration to one or two teeth, and the detection device 2 synchronously detects the vibration signals of the other one or two teeth.

[0062] In another embodiment of the present application, Figure 4 As shown, a hearing aid external device 300 is also provided. The hearing aid external device 300 comprises a sound collecting device 6 and a control device 7, and the control device 7 is configured to be electrically connected to the sound collecting device 6 and the hearing aid intra-oral device 100.

[0063] The control device 7 is configured to receive the collected signal of the sound collection device 6 and the vibration signal detected by the detection device 2 of the hearing aid intra-oral device 100, and after inverting the vibration signal detected by the detection device 2, superimpose it with the signal collected by the sound collection device 6, so as to control the vibration device 1 of the hearing aid intra-oral device 100 to vibrate according to the superimposed signal.

[0064] That is to say, after the external sound signal is collected by the sound collection device 6, it is transmitted to the hearing aid intraoral device 100, driving the vibration device 1 to vibrate, and then driving the teeth and skull to vibrate, and the person receives the sound signal. The sound collection device 6 is generally installed in the ear canal, and the ear canal is in the skull, so the vibration of the skull can also be collected by the sound collection device 6, and the signal will be transmitted to the vibration device 1 again.

[0065] At this time, the detection device 2 collects the vibration signal of the tooth and transmits it to the control device 7 of the hearing aid external unit 300. The control device 7 inverts the vibration signal detected by the detection device 2, and then superimposes the inverted vibration signal with the collected signal of the sound collection device 7. At this time, the signal collected by the sound collection device 6 and the consistent signal collected by the detection device 2 can be suppressed (the transmitted sound signal is offset to avoid secondary sound transmission), which can effectively prevent howling and improve the transmission quality of the sound signal.

[0066] The sound collecting device 6 can be configured to include a common microphone, that is, a microphone is used to collect external sounds, and the product structure is mature, the performance is stable, and the selection is convenient. The microphone is an air conduction microphone.

[0067] In another embodiment of the present application, Figure 5 As shown, a hearing aid is also provided, including an intra-oral hearing aid unit 100 and an external hearing aid unit 300 .

[0068] In another embodiment of the present application, Figure 6 As shown, a control method for a hearing aid is also provided.

[0069] The method comprises:

[0070] S100: Controlling a sound collection device of an external hearing aid to collect sound signals;

[0071] S200: Controlling the detection device of the hearing aid intraoral device to detect the vibration signal of the bone conduction sound transmission organ in the mouth;

[0072] S300: After inverting the vibration signal detected by the detection device, the vibration signal is superimposed with the signal collected by the sound collection device;

[0073] S400: Controlling the vibration device of the hearing aid intraoral device to vibrate according to the superimposed signal.

[0074] After the sound collection device 6 and the detection device 2 respectively collect the air-conducted sound signal and the solid vibration signal, the vibration signal detected by the detection device 2 is inverted and then superimposed with the signal collected by the sound collection device 6. In this way, the sound signal collected by the sound collection device 6 and transmitted from the skull to the ear canal can be suppressed, which can effectively prevent howling and improve the transmission quality of the sound signal.

[0075] It should be noted that the sound collection device 6 collects the sound signal and the detection device 2 detects the vibration signal at the same time, and there is no order relationship. The vibration signal of the detection device 2 that undergoes inversion processing and the signal collected by the sound collection device 6 that is superimposed can be transmitted to the control device 7 at the same time, or there can be a certain delay between the two.

[0076] In another embodiment of the present application, a control device for a hearing aid is provided. The control device includes a processor and a memory. The memory is used to store a computer program, and the processor is used to read and execute the computer program to implement the steps of the above control method.

[0077] In order to reduce the volume of the intra-oral hearing aid unit 100, that is, to design it to be thinner and lighter, the control device of the hearing aid can be arranged in the external hearing aid unit 300, which can also improve the integrity of the product.

[0078] In another embodiment of the present application, a non-transitory computer-readable storage medium is provided, wherein a computer program executable on a processor is stored on the storage medium, wherein when the computer program is executed by the processor, the steps of the above-mentioned hearing aid control method can be implemented.

[0079] In the description herein, the term "plurality" means two or more.

[0080] Although the embodiments disclosed herein are as above, the contents described are only embodiments adopted to facilitate understanding of the present invention and are not intended to limit the present invention. Any technician in the field to which the present invention belongs may make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed herein, but the scope of patent protection of the present invention shall still be defined by the attached claims.
