Description

Technical Field

[0001] This invention relates to the field of hearing aid technology, specifically to a hearing aid with bone conduction and air conduction functions. Background Technology

[0002] A hearing aid is a small amplifier that amplifies sounds that are otherwise inaudible. By utilizing the residual hearing of the hearing-impaired person, the sound can be sent to the auditory center of the brain, allowing them to perceive the sound and bringing great convenience to the hearing-impaired.

[0003] Current hearing aids generally use air conduction or bone conduction, which cannot ensure the integrity of the sound received by the user. Moreover, most hearing aids are ear-hook or headband-style, and cannot be used in both ways at the same time, which cannot meet the comfort requirements of different users. Most hearing aids have a touch switch, which can easily lead to accidental activation when the hearing aid is in use. In order to solve the above problems, this invention proposes a hearing aid with both bone conduction and air conduction functions. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a hearing aid with both bone conduction and air conduction functions.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: a hearing aid with bone conduction and air conduction functions, comprising symmetrical shells, an ear canal fixedly connected to one side of each shell, a bone conduction module fixedly connected to the upper part of the interior of each shell, an air conduction module fixedly connected to the lower part of the interior of each shell, the air conduction modules being located inside the ear canal, a dustproof mesh fixedly connected to the other end of each ear canal, a sealing ear cap fixedly fitted to the outside of each ear canal, a noise reduction device fixedly connected to the interior of each shell, the noise reduction device being located between the bone conduction module and the air conduction module, a charging port fixedly connected to the lower end of each shell, a microphone fixedly connected to the middle of the side of each shell away from the ear canal, a volume regulator fixedly connected to the upper side of each shell, a tuning button fixedly connected to the upper end of each volume regulator, the tuning button being located on the outside of the shell, a touch switch fixedly connected to the other side of the upper end of each shell, the other end of each touch switch having a magnet, the magnet being fixedly connected to the shell; Each ear hook is rotatably connected to the upper middle part of the shell. Each ear hook is fixedly connected to a fixing groove at its lower position. Each fixing groove has a sliding block inside it. Each locking block has a fixing rod fixedly connected to the middle part of its end near the bottom of the fixing groove, which passes through the fixing groove. Each fixing rod has a spherical block fixedly connected to its other end. Each fixing rod is fitted with a return spring, which is located inside the fixing groove. Each ear hook has a fixing plate on its side away from the shell. Each fixing plate has a connecting block fixedly connected to the middle part of its end near the ear hook. The other end of the fixing plate is fixedly connected via a connecting rod.

[0006] Specifically, the upper two sides of the hand switch are provided with symmetrical fixing blocks, the lower ends of the fixing blocks are fixedly connected to the housing, and the fixing blocks are rotatably connected to each other by a rotating rod to form an anti-accidental contact plate.

[0007] Specifically, a push rod is fixedly connected to the end of the anti-accidental touch plate near the magnetic attraction, and the lower end of the push rod is designed with a sloping structure.

[0008] Specifically, each ear hook is fixedly fitted with several anti-slip sleeves.

[0009] Specifically, the ear slots are all located on the side of the two shells that are close to each other, and the fixing slot is located on the same side as the microphone.

[0010] Specifically, the ear hook has a connecting groove corresponding to the connecting block.

[0011] Specifically, the card block is configured with a trapezoidal structure, with the inclined surface of the card block facing the fixed plate. The inclined surface portion of the card block is located within the connecting groove of the connecting block, and the connecting block has a card slot corresponding to the inclined surface portion of the card block.

[0012] The beneficial effects of this invention are: (1) The hearing aid with bone conduction and air conduction functions described in this invention adopts an anti-misoperation structure and a snap-fit ​​structure. When switching the hearing aid on and off, the finger can be used to push the push rod from the bottom to the top to directly contact the hand switch, which is convenient for controlling the opening and closing of the hearing aid. The connecting block slides into the connecting groove on the ear hook. While the connecting block slides into the ear hook, it will press the snap-fit ​​block towards the return spring until the snap-fit ​​block is in the position of the snap-fit ​​groove. The return spring restores its elasticity, thereby snapping the snap-fit ​​block into the snap-fit ​​groove, thereby fixing the fixing plate, the connecting rod and the ear hook.

[0013] (2) The hearing aid described in this invention has both bone conduction and air conduction functions. This invention has both bone conduction and air conduction functions, ensuring the integrity of the sound received by the user and avoiding accidental switch activation. Moreover, it has two wearing methods: ear-hook and headband, allowing the user to choose the wearing method according to the comfort of wearing it, which is practical. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-6As shown, a hearing aid with bone conduction and air conduction functions according to the present invention includes symmetrical shells 1. Each shell 1 has an ear canal 2 fixedly connected to one side. A bone conduction module 3 is fixedly connected to the upper part of the interior of each shell 1, and an air conduction module 4 is fixedly connected to the lower part of the interior of each shell 1. The air conduction modules 4 are all located within the ear canals 2. A dustproof mesh 5 is fixedly connected to the other end of each ear canal 2. A sealing ear cap 6 is fixedly fitted onto the outside of each ear canal 2. A noise reduction device 7 is fixedly connected to the interior of each shell 1. Between the bone conduction module 3 and the air conduction module 4, a charging port 8 is fixedly connected to the lower end of the housing 1. A microphone 9 is fixedly connected to the middle of the side of the housing 1 away from the ear canal 2. A volume regulator 10 is fixedly connected to the upper side of the inside of the housing 1. A tuning button 11 is fixedly connected to the upper end of the volume regulator 10. The tuning button 11 is located on the outside of the housing 1. A touch switch 12 is fixedly connected to the other side of the upper end of the housing 1. A magnet 13 is provided at the other end of the touch switch 12. The magnet 13 is fixedly connected to the housing 1. The upper middle part of the housing 1 is rotatably connected to an ear hook 17. The lower part of the ear hook 17 is fixedly connected to a fixing groove 19. The fixing groove 19 is slidably connected to a locking block 20. The middle part of the locking block 20 near the bottom of the fixing groove 19 is fixedly connected to a fixing rod 201 that passes through the fixing groove 19. The other end of the fixing rod 201 is fixedly connected to a spherical block 202. The fixing rod 201 is fitted with a return spring 21. The return spring 21 is located in the fixing groove 19. The side of the ear hook 17 away from the housing 1 is provided with a fixing plate 22. The middle part of the fixing plate 22 near the ear hook 17 is fixedly connected to a connecting block 221. The other end of the fixing plate 22 is fixedly connected by a connecting rod 23.

[0019] Specifically, the upper sides of the hand switch 12 are provided with symmetrical fixing blocks 14, and the lower ends of the fixing blocks 14 are fixedly connected to the housing 1. The fixing blocks 14 are rotatably connected to an anti-accidental touch plate 16 through a rotating rod 15 to prevent the user from accidentally touching the hand switch 12.

[0020] Specifically, a push rod 161 is fixedly connected to one end of the anti-accidental touch plate 16 near the magnet 13, and the lower end of the push rod 161 is designed with a slanted structure. When the anti-accidental touch plate 16 is opened, simply push the push rod 161 upwards with your finger from the lower end. At this time, your finger can directly contact the touch switch 12, which is convenient for controlling the hearing aid to be turned on and off.

[0021] Specifically, each ear hook 17 is fixedly fitted with several anti-slip sleeves 18 to prevent the ear hook 17 from slipping on the ear and to prevent the hearing aid from falling off.

[0022] Specifically, the ear slots 2 are all located on the side of the two shells 1 that are close to each other, and the fixing slot 19 is located on the same side as the microphone 9. This prevents the fixing slot 19 from digging into the ear when worn.

[0023] Specifically, the ear hook 17 has a connecting groove 171 corresponding to the connecting block 221. This allows the connecting block 221 to slide smoothly on the ear hook 17, facilitating the fixing plate 22 and the connecting rod 23 to be fixed to the ear hook 17 via the connecting block 221.

[0024] Specifically, the locking block 20 has a trapezoidal structure, with its inclined surface facing the fixing plate 22. The inclined portion of the locking block 20 is located within the connecting groove 171 of the connecting block 221. The connecting block 221 has a corresponding slot 2211 on it. This allows the locking block 20 to be engaged in the slot 2211, thus fixing the fixing plate 22 to the ear hook 17, and consequently fixing the connecting rod 23 to the ear hook 17.

[0025] When using the hearing aid, first place the connecting rod 23 behind the head, then hang the ear hook 17 on the ear. The anti-slip sleeve 18 on the ear hook 17 prevents it from slipping on the ear and falling off. Next, rotate the housing 1 until the sealing ear cap 6 is comfortably inserted into the ear. Then, use your finger to push upwards from the lower end of the push rod 161 until you can directly touch the touch switch 12 to turn on the hearing aid. Then, adjust the volume using the volume adjustment button 11. The noise reduction device 7 processes external noise, and the processed sound is transmitted to the user's ear through the bone conduction module 3 or the air conduction module 4, allowing the user to hear external sounds smoothly. If the connecting rod 23 is not needed when wearing the ear hook 17, simply pull the ball block 202 outward to remove the connecting rod 23. When installing the connecting rod 23, simply put the connecting block 221 back into the connecting slot 171. As the connecting block 221 slides into the ear hook 17, it will press the locking block 20 towards the return spring 21 until the locking block 20 is located at the upper end of the slot 2211. The return spring 21 then returns to its elasticity, thereby locking the locking block 20 into the slot 2211, thus fixing the connecting rod 23. This allows for both ear hook and headband wearing methods, and the operation is simple and easy to use.
