Technical Field
[0001] The present invention relates to an adaptive bone conduction transducer fixing device and a bone conduction hearing aid device. Background Art
[0002] A bone conduction transducer converts an audio signal into vibrations and transmits them to human tissues and bones, and further transmits them to the auditory nerve, so that the wearer can hear sounds. Audio products using bone conduction transducers belong to ergonomic wearable devices. The products need to adapt to different ergonomic requirements. For example, the pressure on the contact part between the bone conduction transducer and the wearer needs to be balanced, and there should be no different pressure during wearing due to different head shapes of the wearer. Another example is that the travel of the contact part between the bone conduction transducer and the wearer (such as the mastoid bone, auricle, preauricular cranial bone, etc.) needs to have a certain degree of scalability and self - adaptability to adapt to different ergonomic characteristics of the contact parts of different wearers.
[0003] Therefore, there is a need for a bone conduction transducer fixing method and structure to adapt to different ergonomics, especially a need for a fixing method and structure that can adjust the travel and adapt to the travel. Summary of the Invention

[0014] In one embodiment, the elastic support assembly 200 further includes a first fixing member 420 that is assembled and connected to the external support member 410 and has one end indented. The indented end of the first fixing member 420 limits the stroke of the second support member 203 moving towards the bone conduction transducer assembly 100, so that the compression stroke of the elastic member 201 is limited within the first stroke adjustment gap 710 between the second support member 203 and the first fixing member 420.
[0015] In one embodiment, the elastic support assembly 200 further includes a second fixing member 422 that is assembled and connected to the external support member 410 and has both ends indented.

[0056] An embodiment of the present invention protects an adaptive bone conduction transducer fixing device.
[0057] The present invention will be further described below in conjunction with different embodiments of the present invention.
[0058] As Figure 1 shown, the adaptive bone conduction transducer fixing device of the embodiment of the present invention mainly includes the following parts: a vibration transmission assembly 600, a bone conduction transducer assembly 100, an elastic support assembly 200, and also includes a partial structure of an external support member 410 on the bone conduction hearing aid for fixing and supporting. Further, in order to achieve an adaptive stroke control with a larger stroke adjustment range, a stroke adjustment assembly can be added. The specific structures of each component are as follows:
[0059] The vibration transmission assembly 600 is mainly composed of a vibration transmission part 601, a vibration transmission corrugated part 602, and a vibration transmission fixing part 603. The outer surface of the vibration transmission part 601 is used to fit the user's skin and can transmit sound signals to the user's bones. The vibration transmission corrugated part 602 extends from the edge of the vibration transmission part 601 to the vibration transmission fixing part 603, making the vibration transmission assembly 600 in the shape of a cylinder with one end open. The cross-section of the cylindrical structure can be set as a square cylinder, a circular cylinder, etc. according to specific circumstances. Usually, it is set as a square cylinder shape adapted to the structure of the bone conduction transducer 100. Among them, the vibration transmission part 601 is configured to contact the wearer's skin on its outer surface when the wearer uses it. The vibration transmission corrugated part 602 is configured to have a corrugated structure that absorbs part of the telescopic stroke. The vibration transmission fixing part 603 is connected to the external support member 410 on the bone conduction hearing aid by a fixed bonding connection form and / or a snap pressing connection form, and has a supporting function.
[0060] The bone conduction transducer assembly 100 forms a firm contact with the inner surface of the vibration transmission part 601, or is fixedly connected through the fixing part 501 of the bonding part, so that the whole bone conduction transducer assembly 100 is generally accommodated inside the vibration transmission assembly 600 with the bottom surface facing outward. The bone conduction transducer assembly 100 includes a bone conduction transducer 101, a bone conduction transducer vibration transmission plate 102, and a vibration shaft 103 that connects the bone conduction transducer 101 and the bone conduction transducer vibration transmission plate 102 to integrate the two into one; the bone conduction transducer vibration transmission plate 102 faces the inner surface of the vibration transmission part 601, and preferably can be connected in a fixed bonding form, that is, the inner surface of the vibration transmission part 601 is connected by using the bonding and fixing part 501. A vibration gap 701 is formed between the vibration transmission corrugated part 602 and the outer surface of the bone conduction transducer 101 to prevent contact and friction between the bone conduction transducer 101 and the vibration transmission assembly 600 during vibration, which may interfere with signal transmission.
[0061] Furthermore, in order to reduce the volume and save space, the bone conduction transducer 101 can integrate the bone conduction transducer vibration transmission plate 102 and the vibration shaft 103 into one. At this time, the bone conduction transducer vibration transmission plate 102 evolves into a vibration surface of the bone conduction transducer 101, and the vibration shaft 103 is built-in.
[0062] The elastic support assembly 200 includes an elastic structure, which forms a stable contact with the outer bottom surface of the bone conduction transducer assembly 100 away from the vibration transmission part 601, or is fixedly connected through the bonding and fixing part 502. The elastic support assembly 200 is mainly composed of an elastic member 201, a first support member 202, and a second support member 203. Both ends of the elastic member 201 are respectively fixed on a side surface of the first support member 202 and the inner surface of the second support member 203; the other side surface of the first support member 202 is in contact with or fixedly connected to the bone conduction transducer 101. Specifically, the first support member 202 is in firm contact connection with the bone conduction transducer 101 away from the inner side surface of the vibration transmission assembly 600, that is, the non-vibrating bottom surface, or is fixedly bonded through the bonding and fixing part 502.
[0063] The elastic support assembly 200 further includes a first fixing member 420 with one end indented, which can support and limit the entire elastic support assembly 200. The external support member 410 is assembled and connected to the first fixing member 420. The second support member 203 can be configured as a flat plate, or a cylindrical shape with one end closed or indented as shown in the figure. The indented end of the first fixing member 420 limits the stroke of the second support member 203 moving towards the bone conduction transducer assembly 100, so that the compression stroke of the elastic member 201 is limited within the first stroke adjustment gap 710 between the second support member 203 and the first fixing member 420. Specifically, the first fixing member 420 can be a hollow cylindrical shape, or can be composed of a plurality of semi-cylindrical or first fixing members 420, 421 with one end indented and bent, which jointly limit the second support member 203 from moving in other directions except the axial direction of the elastic member 201, and jointly limit the maximum stroke of the second support member 203 moving along the axial direction of the elastic member 201 not exceeding the first stroke adjustment gap 710.
[0064] When the outer surface of the vibration transmission part 601 contacts the skin of the wearer and is squeezed in the inward direction, the vibration transmission part 601 pushes the bone conduction transducer assembly 100 towards the elastic support assembly 200, causing displacement and generating a stroke. At this time, the elastic member 201 in the elastic support assembly 200 is squeezed and contracts and deforms, absorbing the generated displacement stroke; at the same time, the vibration transmission corrugated part 602 generates corresponding convergence, absorbing the displacement caused by the displacement stroke of the vibration transmission part 601.
[0065] Correspondingly, when the squeezing force on the outer surface of the vibration transmission part 601 disappears, the elastic member 201 in the elastic support assembly 200 releases the contraction deformation, pushes the bone conduction transducer assembly 100 towards the vibration transmission part 601, causing displacement and generating a stroke; at the same time, the vibration transmission corrugated part 602 generates corresponding stretching, absorbing the displacement caused by the displacement stroke of the vibration transmission part 601.
[0066] Therefore, the combination of the elastic support assembly 200, the bone conduction transducer assembly 100, and the vibration transmission assembly 600 can realize a bone conduction transducer fixing device with an adaptive stroke to a certain extent.
[0067] The stroke adjustment assembly is used to adjust the elastic support assembly 200 to be compressed towards the bone conduction transducer assembly 100 within a certain range, so as to push the vibration transmission part 601 of the vibration transmission assembly 600 to fit the user's skin with the most appropriate tightness, achieving the best sound transmission effect. Among them, the stroke adjustment assembly can be a motor stroke adjustment assembly 300, a longitudinally arranged lead screw stroke adjustment assembly 301, a horizontally arranged lead screw stroke adjustment assembly 302, or a ball screw stroke adjustment assembly 330.
[0068] Figure 1The embodiment in [description] realizes the active stroke adjustment mode of the motor by using the motor stroke adjustment assembly 300, which mainly consists of an inclined fixed block 401, a wedge-shaped adjustment block 303, a micro motor 310, and a motor transmission shaft 311 that converts the rotation of the micro motor 310 into axial forward and backward movement.
[0069] Among them, the driving end of the motor transmission shaft 311 is fixed at the bottom of the wedge-shaped adjustment block 303, and the wedge-shaped adjustment block 303 is clamped between the inclined fixed block 401 and the elastic support assembly 200. The axial direction of the motor transmission shaft 311 is parallel to the inclined surface direction of the wedge-shaped adjustment block 303; the inclined surface of the wedge-shaped adjustment block 303 is in parallel contact with the inclined surface of the inclined fixed block 401 and can move up and down along the inclined surface direction of the inclined fixed block 401; the forward and reverse rotations output by the fixed micro motor 310 are converted by the motor transmission shaft 311 into pushing the wedge-shaped adjustment block 303 to move upward and downward along the axial direction of the motor transmission shaft 311; due to the wedge-shaped adjustment block 303 being restricted by the inclined fixed block 401, the upward and downward movement of the wedge-shaped adjustment block 303 along the axial direction of the motor transmission shaft 311 is converted into the axial forward and backward movement of the second support member 203 along the elastic member 201; the forward and backward movement of the second support member 203 is further transmitted to the bone conduction transducer 101 through the elastic member 201 and the first support member 202; the bone conduction transducer 101 transmits the forward and backward movement to the vibration transmission part 601 through the bone conduction transducer vibration transmission plate 102 and the vibration shaft 103; finally, the forward and backward movement stroke of the vibration transmission part 601 is adjusted by the forward and reverse rotations of the micro motor 310. When the vibration transmission part 601 is pushed and pulled back, the vibration transmission corrugated part 602 expands and converges accordingly.
[0070] Therefore, based on the elastic support assembly 200, the bone conduction transducer assembly 100, and the vibration transmission assembly 600, the motor stroke adjustment assembly 300 further adjusts the forward and backward movement stroke of the vibration transmission part 601, thereby realizing an adjustable stroke adaptive bone conduction transducer fixing device with an active motor stroke adjustment mode.
[0071] Furthermore, in Figure 1 In the first embodiment of the present invention shown, the adjustable stroke adaptive bone conduction transducer fixing device may further include one or more pressure sensors 110 configured to collect the force exerted by the elastic support assembly 200 on the bone conduction transducer assembly 100. The pressure sensor 110 is configured on the outer side surface of the second support member 203, and the pressure sensor 110 is connected to the main board of the bone conduction hearing device and can transmit the detected pressure signal to the main board for the main board to drive the motor and adjust the stroke of the stroke adjustment assembly.
[0072] Furthermore, in Figure 1In the first embodiment of the present invention shown, one or more adjustable stroke adaptive bone conduction transducer fixing devices may also be configured with sensors 111 for collecting the wearing state of the wearer. The sensors 111 are configured on the external support member 410 and face outward. The sensors 111 include at least one of a proximity sensor, an infrared sensor, a temperature sensor, and a humidity sensor. These sensors 111 are connected to the main board of the bone conduction hearing device, enabling the controller to automatically adjust the switch state according to changes in the wearer's wearing state. For example, when approaching a certain distance from the wearer's skin, the bone conduction hearing aid is directly turned on, and when leaving a certain distance from the wearer's skin, the bone conduction hearing aid is directly turned off.
[0073] In Figure 2 In the second embodiment shown, the ball screw adjustment stroke assembly 330 realizes the active adjustment of the stroke by the screw motor. The structural design methods, installation methods, and the association methods between the various components of its vibration transmission assembly 600, bone conduction transducer assembly 100, elastic support assembly 200, etc. are similar to those of the first embodiment.
[0074] Among them, the ball screw adjustment stroke assembly 330 is composed of a ball screw 322, a screw motor 323, and a wedge adjustment block 304. Among them, the fixed screw motor 323 advances or retracts the ball screw 322 in the axial direction, and the ball screw 322 advances or retracts the wedge adjustment block 303 in the axial direction.
[0075] Since the wedge adjustment block 304 is restricted by the inclined fixing block 401, the advancement or retraction of the wedge adjustment block 304 along the axial direction of the ball screw 322 is converted into the advancement and retraction of the second support member 203 along the axial direction of the elastic member 201; the advancement and retraction of the second support member 203 further advance and retract the transducer 101 through the elastic member 201 and the first support member 202; the transducer 101 transmits the advancement and retraction to the vibration transmission part 601 through the bone conduction transducer vibration transmission plate 102 and the vibration shaft 103; finally, the driving of the ball screw 322 by the fixed screw motor 323 is used to adjust the advancement and retraction stroke of the vibration transmission part 601. When the vibration transmission part 601 is advanced and retracted, the vibration transmission corrugated part 602 expands and converges accordingly.
[0076] Therefore, based on the elastic support assembly 200, the bone conduction transducer assembly 100, and the vibration transmission assembly 600, the ball screw adjustment stroke assembly 330 further adjusts the advancement and retraction stroke of the vibration transmission part 601, thereby realizing an adjustable stroke adaptive bone conduction transducer fixing device with an active adjustment of the stroke by the screw motor.
[0077] Furthermore, in Figure 2In the second embodiment of the present invention as shown, the adjustable-stroke adaptive bone conduction transducer fixing device may further include one or more pressure sensors 110 configured to collect the force exerted by the elastic support assembly 200 on the bone conduction transducer assembly 100. The pressure sensor 110 is configured on the outer side surface of the second support member 203. The pressure sensor 110 is connected to the main board of the bone conduction hearing device and can transmit the detected pressure signal to the main board for the main board to drive the motor and adjust the stroke of the stroke adjustment assembly.
[0078] Furthermore, in Figure 2 In the second embodiment of the present invention as shown, the adjustable-stroke adaptive bone conduction transducer fixing device may also include one or more sensors 111 configured to collect the wearing state of the wearer. The sensor 111 is configured on the external support member 410 and faces outward. The sensor 111 includes at least one of a proximity sensor, an infrared sensor, a temperature sensor, and a humidity sensor. These sensors 111 are connected to the main board of the bone conduction hearing device, enabling the controller to automatically adjust the switch state according to changes in the wearer's wearing state. For example, when approaching a certain distance from the wearer's skin, the bone conduction hearing aid is directly turned on, and when leaving a certain distance from the wearer's skin, the bone conduction hearing aid is directly turned off.
[0079] In Figure 3 In the third embodiment as shown, the longitudinal screw rod adjustment stroke assembly 301 is used to achieve the active adjustment of the stroke by the longitudinal screw rod. The structural design, installation method, and the association method between the various components of its vibration transmission assembly 600, bone conduction transducer assembly 100, elastic support assembly 200, etc. are similar to those in the first embodiment. The longitudinal screw rod adjustment stroke assembly 301 mainly consists of an inclined fixing block 401, a wedge-shaped adjustment block 305, and a longitudinal screw rod mechanism. The wedge-shaped adjustment block 305 is clamped between the inclined fixing block 401 and the elastic support assembly 200 and is fixedly connected to the driving end of the screw rod mechanism. The longitudinal screw rod mechanism includes a longitudinal nut tube 312 for driving the wedge-shaped adjustment block 305, a longitudinal screw rod 313 that matches the longitudinal nut tube 312, and a longitudinal screw rod stroke fixing block 320 that restricts the axial movement of the longitudinal screw rod 313.
[0080] Among them, the longitudinal nut tube 312 is fixed at the bottom of the wedge-shaped adjustment block 305, and the axial direction of the longitudinal nut tube 312 is parallel to the inclined surface direction of the wedge-shaped adjustment block 305; the inclined surface of the wedge-shaped adjustment block 305 is in parallel contact with the inclined surface of the inclined fixing block 401 and can move up and down along the inclined surface direction of the inclined fixing block 401; the longitudinal screw rod 313 that matches the longitudinal nut tube 312 can rotate in the longitudinal nut tube 312; the fixed longitudinal screw rod stroke fixing block 320 restricts the axial movement of the longitudinal screw rod 313 and does not restrict the axial rotation of the longitudinal screw rod 313.
[0081] The longitudinally arranged lead screw 313 rotates in the positive or negative axial direction, pushing or pulling back the longitudinally arranged nut tube 312 and the wedge-shaped adjustment block 305 to move upward or downward along the axial direction of the longitudinally arranged nut tube 312; since the wedge-shaped adjustment block 305 is restricted by the obliquely fixed block 401, the upward and downward movements of the wedge-shaped adjustment block 305 are converted into the advancement and retraction of the second support member 203 along the axial direction of the elastic member 201; the advancement and retraction of the second support member 203 further advance and retract the transduction transducer 101 through the elastic member 201 and the first support member 202; the transduction transducer 101 transmits the advancement and retraction to the vibration transmission part 601 through the bone conduction transducer vibration transmission plate 102 and the vibration shaft 103; finally, the advancement and retraction stroke of the vibration transmission part 601 is adjusted by the forward and reverse rotation of the micro motor 310. When the vibration transmission part 601 is advanced and retracted, the vibration transmission corrugated part 602 expands and converges accordingly.
[0082] Therefore, based on the elastic support assembly 200, the bone conduction transducer assembly 100, and the vibration transmission assembly 600, the longitudinally arranged lead screw adjustment stroke assembly 301 further adjusts the advancement and retraction stroke of the vibration transmission part 601, thereby realizing an adjustable stroke adaptive bone conduction transducer fixing device with an actively adjustable stroke mode of the longitudinally arranged lead screw.
[0083] Furthermore, in Figure 3 In the third embodiment of the present invention shown, the adjustable stroke adaptive bone conduction transducer fixing device may further include one or more pressure sensors 110 configured to collect the force exerted by the elastic support assembly 200 on the bone conduction transducer assembly 100. The pressure sensors 110 are arranged on the outer side surface of the second support member 203.
[0084] Furthermore, in Figure 3 In the third embodiment of the present invention shown, the adjustable stroke adaptive bone conduction transducer fixing device may also include one or more sensors 111 configured to collect the wearing state of the wearer. The sensors 111 are arranged on the external support member 410 and face outward. The sensors 111 include at least one of a proximity sensor, an infrared sensor, a temperature sensor, and a humidity sensor.
[0085] In Figure 4 In the fourth embodiment shown, the laterally arranged lead screw adjustment stroke assembly 302 is used to realize the actively adjustable stroke mode of the laterally arranged lead screw. The structural design, installation method, and the connection method between the components of its vibration transmission assembly 600, bone conduction transducer assembly 100, elastic support assembly 200, etc. are similar to those in the first embodiment, but Figure 1 、 Figure 2 and Figure 3 the limiting structure of the second support member 203 in the embodiment is different.
[0086] Specifically, this embodiment further includes a second fixing member 422 for limiting the second support member 203. It is assembled and connected to the external support member 410 and has both ends indented. The two indented ends respectively limit the stroke of the forward and backward movement of the second support member 203, so that the compression stroke of the elastic member 201 is limited within the second stroke adjustment gap 711 between the second support member 203 and the second fixing member 422. Specifically, the second fixing member 422 can be a hollow cylindrical shape, or can be composed of a plurality of semi-cylindrical shapes or second fixing members 422 and 423 that are indented at one end and bent. The combination of the second fixing members 422 and 423 restricts the second support member 203 from moving in other directions except the axial direction of the elastic member 201, and the combination restricts the maximum stroke of the second support member 203 moving along the axial direction of the elastic member 201 not to exceed the second stroke adjustment gap 711.
[0087] The horizontally arranged screw rod adjustment stroke assembly 302 of this embodiment mainly consists of a horizontally arranged nut tube 314 fixed on the outer surface of the second support member 203 for driving it, a horizontally arranged screw rod 315 that matches the horizontally arranged nut tube 314, and a horizontally arranged screw rod stroke fixing block 321 that restricts the axial movement of the horizontally arranged screw rod 315.
[0088] Among them, the axial direction of the horizontally arranged nut tube 314 is parallel to the axial direction of the elastic member 201; the horizontally arranged screw rod 315 that matches the horizontally arranged nut tube 314 can rotate in the horizontally arranged nut tube 314; the fixed horizontally arranged screw rod stroke fixing block 321 restricts the horizontally arranged screw rod 315 from moving axially and does not restrict the horizontally arranged screw rod 315 from rotating axially.
[0089] When the horizontally arranged screw rod 315 rotates forward or backward axially, it pushes or pulls back the horizontally arranged nut tube 314, and then pushes or pulls back the second support member 203; the forward and backward movement of the second support member 203 is further pushed and pulled back through the elastic member 201 and the first support member 202 to the transduction element 101; the transduction element 101 transmits the forward and backward movement to the vibration transmission part 601 through the bone conduction transducer vibration transmission plate 102 and the vibration shaft 103; finally, by the forward and reverse rotation of the micro motor 310, the forward and backward movement stroke of the vibration transmission part 601 is adjusted. When the vibration transmission part 601 is pushed and pulled back, the vibration transmission corrugated part 602 expands and converges accordingly.
[0090] Therefore, based on the elastic support assembly 200, the bone conduction transducer assembly 100, and the vibration transmission assembly 600, the horizontally arranged screw rod adjustment stroke assembly 302 further adjusts the forward and backward movement stroke of the vibration transmission part 601, and further realizes an adjustable stroke adaptive bone conduction transducer fixing device with an actively adjustable stroke method of the horizontally arranged screw rod.
[0091] Furthermore, in Figure 4In the fourth embodiment of the present invention as shown, one or more adjustable stroke adaptive bone conduction transducer fixing devices may further be configured with sensors 111 for collecting the wearing state of the wearer. The sensors 111 are configured on the outer support member 410 and face outward. The sensors 111 include at least one of a proximity sensor, an infrared sensor, a temperature sensor, and a humidity sensor.
[0092] In Figures 1 to 4 In the fourth embodiment of the present invention as shown, the wedge-shaped adjusting blocks 303, 304, and 305 may also be set to Figure 6 the structure of the wedge-shaped adjusting block 306 in the cross-sectional view as shown. The common feature of the wedge-shaped adjusting blocks 303, 304, 305, and the wedge-shaped adjusting block 306 is that the surfaces of the four wedge-shaped adjusting blocks in contact with the oblique fixing block 401 are not parallel to the surfaces of the four wedge-shaped adjusting blocks in contact with the outer side surface of the second support member 203 or the sensors 111.
[0093] In Figure 5 The fifth embodiment as shown realizes a passive adaptive bone conduction transducer fixing device. The structural design methods, installation methods, and the connection methods between the components of its vibration transmission assembly 600, bone conduction transducer assembly 100, elastic support assembly 200, etc. are similar to those in the first embodiment, but do not include an adjusting stroke assembly. Instead, its simplified fixing structure assembly is replaced with a vertical fixing block 402 and a limit fixing block 424; the vertical fixing block 402 restricts the second support member 203 from moving axially along the elastic member 201; the combination of two integrally or symmetrically arranged limit fixing blocks 424 and 425 restricts the second support member 203 from moving in other directions except the axial direction of the elastic member 201.
[0094] When the outer surface of the vibration transmission part 601 contacts the skin of the wearer and is squeezed in the inward direction, the vibration transmission part 601 pushes the bone conduction transducer assembly 100 towards the elastic support assembly 200, causing displacement and generating a stroke. At this time, the elastic member 201 in the elastic support assembly 200 is squeezed and undergoes shrinkage deformation to absorb the displacement stroke that occurs; at the same time, the vibration transmission corrugated part 602 generates corresponding convergence to absorb the displacement caused by the displacement stroke of the vibration transmission part 601.
[0095] Correspondingly, when the extrusion on the outer surface of the vibration transmission part 601 disappears, the elastic member 201 in the elastic support assembly 200 releases the shrinkage deformation, pushes the bone conduction transducer assembly 100 towards the vibration transmission part 601, causing displacement and generating a stroke; at the same time, the vibration transmission corrugated part 602 generates corresponding stretching to absorb the displacement caused by the displacement stroke of the vibration transmission part 601.
[0096] Therefore, by simplifying the fixed structure assembly in combination with the elastic support assembly 200, the bone conduction transducer assembly 100, and the vibration transmission assembly 600, a passive adjustable stroke adaptive bone conduction transducer fixing device can be realized.
[0097] The above content is a further detailed description of the present invention in combination with specific implementation manners, which is convenient for readers to understand. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions, substitutions, and function module deletions can still be made, and all should be regarded as belonging to the protection scope of the present invention.
