Description

Technical Field

[0001] The present invention relates to the technical field of hearing aids, and more particularly to a bone conduction hearing aid. Background Art

[0002] Bone conduction hearing aids use bones as a medium for sound conduction, bypassing the outer ear and middle ear, and directly transmitting sound signals to the inner ear, thereby stimulating the auditory nerve to produce auditory perception. This process does not rely on the integrity of the outer ear and middle ear, so it is particularly suitable for people with hearing loss caused by ear diseases such as external auditory canal atresia and otitis media.

[0003] In the existing published technical literature, the Chinese patent publication number CN217591095U discloses a snap-on bone conduction hearing aid that can be used on one side. The bone conduction hearing aid mainly uses the first bending part and the second bending part to firstly use the first combination part and the second combination part to respectively achieve the effect of forming bone conduction vibration on one side, and then further uses the characteristics of the first combination part and the second combination part that can be structurally spliced. There is also an electrical connection structure in the combination structure, which can achieve data exchange and transmission, and facilitate the adaptive adjustment of users with differential deafness in the left and right ears. However, the bone conduction hearing aid still has the following problems in the process of hearing aid use.

[0004] Bone conduction hearing aids use a vibrator that fits tightly against the user's skull to convert electrical signals into mechanical vibrations, which are transmitted to the inner ear through the skull. The vibrations can effectively bypass the outer ear and middle ear and directly stimulate the auditory cells in the inner ear to achieve hearing aid operation. However, when the vibrator contacts the user's skull, force needs to be applied to achieve fit. Excessive force applied to the vibrator will cause a decrease in comfort. Applying a smaller force makes it difficult to make the vibrator fit tightly against the skull to achieve hearing aid, which will result in a worse hearing aid effect. The user is required to constantly fine-tune the extrusion force of the vibrator until it is adjusted to an acceptable extrusion range. Therefore, it is difficult to achieve high-precision adjustment according to the specified pressure, and the hearing aid has poor accuracy in use. For this reason, a bone conduction hearing aid is provided. Summary of the invention

[0016] Technical effects and advantages of the present invention:

[0017] The present invention uses a double-linked extrusion mechanism, and a wireless controller starts two micromotors. The two micromotors respectively drive two linked screws to rotate, and the two sleeve concave blocks respectively carry two linked rods to move left, and the linked sleeve rods push the extrusion support rod to move backward, and the hinged concave plate carries the pressure sensor to move backward, pushing the partition plate to carry the bone conduction vibrator to move backward for extrusion. The bone conduction vibrator carries the vibration end and is extruded at the position of the skull skin on one side. The hinged concave plate is extruded on the pressure sensor to realize pressure sensing. The vibration end can realize double-linked extrusion at a specified pressure, and the vibration end and the bone conduction vibrator can realize high-precision adjustment of the extrusion according to the specified pressure, which will not cause excessive extrusion of the vibration end, and can ensure that the vibration end is closely fitted according to the specified extrusion force, so that the bone conduction vibrator has a better bone conduction hearing aid effect, and the accuracy of hearing aid use is greatly improved.

[0018] The present invention adopts a guide calibration mechanism. When the hinged concave plate is pressed on the pressure sensor, the hinged concave plate drives the two sliding sleeves to move backward, pushing the partition support guide column. At the same time, the sliding sleeve drives the sleeve slide bar to move backward, and the sleeve slide bar carries the extrusion column to move backward. The value sensed by the calibration pressure sensor is compared with the value sensed by the pressure sensor to ensure that the vibration end is squeezed at the user's skull skin position according to the specified pressure, realize the guide calibration extrusion, and improve the accuracy of hearing aid use.

[0019] The present invention adopts a uniform speed guiding component. When the linkage screw rotates, the linkage screw will carry the sensing shaft to rotate inside the support frame. The sensing shaft realizes speed sensing on the speed sensor, ensuring that the micro motor carrying the linkage screw can realize rotation adjustment at a specified speed. At the same time, the bone conduction vibrator will carry the sliding sleeve to move backward. The sliding sleeve will slide in a sealed manner on the inner wall of the sealing ring. The bone conduction vibrator will drive multiple linkage blocks to move backward synchronously. The sleeve block will move backward along the outer wall of the pillar. The backward movement of the bone conduction vibrator will realize uniform speed guiding and adjusting pressure at a specified speed and a specified position, avoiding offset of the bone conduction vibrator and the vibration end or different movement speeds, thereby improving the accuracy of hearing aid use.

[0020] The interaction of the above multiple actions first causes the two sleeve recesses to carry the two linkage rods to move left and squeeze respectively, and the bone conduction vibrator carries the vibration end to achieve double linkage precise squeezing at a specified pressure, and then the bone conduction vibrator moves backward to achieve uniform guidance and pressure adjustment at a specified speed and position, and finally the sleeve slide carries the squeezing column to move backward, and the value sensed by the pressure sensor is compared with the value sensed by the pressure sensor. In summary, the vibration end on the bone conduction vibrator can be adjusted with high precision according to the specified pressure, which will not cause excessive squeezing of the vibration end, and can ensure that the vibration end fits tightly according to the specified squeezing force, so that the bone conduction vibrator has a better bone conduction hearing aid effect and greatly improves the accuracy of hearing aid use.

Multiple pillars 31 are arranged and arranged in a circular ring with equal spacing, and the vertical cross-sections of the multiple pillars 31 are all circular, the support frame 2 and the speed sensor 37 are fixedly connected to the support block 38, and the support block 38 is made of stainless steel.

[0041] The method of using the bone conduction hearing aid of the present invention is as follows:

[0042] Step 1: When wearing, put the bending strip 15 on the back of the user's neck, and then put the two ear-hanging strips 13 on the two ears respectively, and the two shells 1 are respectively located on the skull in front of the ears, and the vibration end 35 contacts the skull skin.

[0043] Step 2, during double-linkage extrusion, the pressure value of the extrusion contact is set through the wireless controller 21, and then the two micromotors 4 are started through the wireless controller 21. The two micromotors 4 respectively drive the two linkage screws 3 to rotate, and the linkage screws 3 carry the two sleeve concave blocks 5 to move left under the action of the threads. The two sleeve concave blocks 5 respectively carry the two linkage rods 6 to move left, and the linkage rod 6 drives the linkage sleeve rod 7 to move, and the linkage sleeve rod 7 pushes the extrusion support rod 8 to move backward. In this way, the extrusion support rod 8 drives the hinged concave plate 9 to move backward, and the hinged concave plate 9 carries the pressure sensor 10 to move backward, and the pressure sensor 10 carries the push partition 11 to move backward.

[0044] The partition 11 is pushed to carry the bone conduction vibrator 12 and squeeze it backward. The bone conduction vibrator 12 carries the vibration end 35 and squeezes it on the skin of one side of the skull, while the other vibration end 35 squeezes it on the skin of the other side of the skull. The hinged concave plate 9 squeezes on the pressure sensor 10 to realize pressure sensing.

[0045] Step three, during uniform speed guiding, when the linkage screw 3 rotates, the linkage screw 3 will carry the sensing shaft 36 to rotate inside the support frame 2, the sensing shaft 36 realizes speed sensing on the speed sensor 37, and the support frame 2 supports the support block 38, the support block 38 can provide a stable supporting force for the speed sensor 37, the speed sensor 37 realizes speed sensing for the linkage screw 3, until the speed sensor 37 senses the speed value and the value set by the wireless controller 21 is the same, then the wireless controller 21 is used to ensure that the micro motor 4 carries the linkage screw 3 to rotate at the specified speed to avoid excessive extrusion speed.

[0046] At the same time, the bone conduction vibrator 12 moves backward, and the bone conduction vibrator 12 will carry the sliding sleeve 28 to move backward. The sliding sleeve 28 slides in a sealed manner on the inner wall of the sealing ring 29. At the same time, the housing 1 supports the support ring 30, and the support ring 30 supports the sealing ring 29. The sealing ring 29 can slide closely with the sliding sleeve 28. At the same time, the bone conduction vibrator 12 will drive multiple linkage blocks 34 to move backward synchronously. The linkage blocks 34 carry the linkage bars 33 to move backward. The linkage bars 33 drive the socket blocks 32 to move backward, and the socket blocks 32 move backward along the outer wall of the pillar 31. At the same time, the housing 1 supports multiple linkage bars 33, so that the backward movement of the bone conduction vibrator 12 can achieve uniform guidance and pressure adjustment at a specified speed and position, avoiding the bone conduction vibrator 12 and the vibration end 35 from being offset or moving at different speeds, and the bone conduction vibrator 12 and the vibration end 35 can be precisely adjusted. When the pressure sensor 10 senses the pressure value set by the wireless controller 21, the micro motor 4 is turned off through the wireless controller 21, and the speed sensor 37 senses the speed as zero, quickly achieving precise pressure control and regulation. The two vibration ends 35 can fit the skin on both sides of the user's skull according to the specified pressure.

[0047] Step 4: During the guide calibration, when the hinged concave plate 9 is pressed on the pressure sensor 10, the two sliding sleeves 22 are driven to move backward through the hinged concave plate 9, and the sliding sleeves 22 slide backward along the outer wall of the guide column 23, and push the partition 11 to support the guide column 23. At the same time, the sliding sleeve 22 drives the sleeve slide 24 to move backward, and the sleeve slide 24 slides backward along the outer wall of the slide bar 27. The sleeve slide 24 carries the extrusion column 25 to move backward, and the extrusion column 25 is guided to be extruded on the calibration pressure sensor 26. The value sensed by the calibration pressure sensor 26 is compared with the value sensed by the pressure sensor 10. When the sensed values ​​are the same as the pressure values ​​set by the wireless controller 21, the vibration end 35 can calibrate the pressure to ensure that the vibration end 35 is pressed on the user's skull skin position according to the specified pressure. When the difference between the sensor values ​​of the calibration pressure sensor 26 and the pressure sensor 10 is large, the drive of the micromotor 4 is stopped immediately, and the pressure sensor 10 is known to be damaged, so that it is convenient to know the repair in time, and avoid people continuing to use the pressure sensor 10 when it is damaged, and ensure that the bone conduction vibrator 12 and the vibration end 35 are in contact according to the specified pressure for bone conduction hearing aid.

[0048] Step 5. When using bone conduction hearing aid, the battery 18 is supported by the battery shell 16. The battery 18 supplies power to the connecting wire 17 and multiple microphones 20. The multiple microphones 20 collect sound. The sound is amplified by the circuit board 19 after noise reduction and is transmitted to the connecting wire 17. The connecting wire 17 guides the sound along the ear hook strip 13 to the bone conduction vibrator 12, and the connecting wire 17 can be transmitted to another bone conduction vibrator 12 at the same time. The collection shell 14 can protect the connecting wire 17. In this way, the bone conduction vibrator 12 realizes vibration transmission through the vibration end 35 to realize the bone conduction hearing aid operation.
