Description

Technical Field

[0001] This utility model relates to the field of hearing aid design, and in particular to a bone conduction hearing aid. Background Technology

[0002] Many people with hearing impairments use hearing aids to compensate for their hearing loss. In the past, most hearing aids were in-ear hearing aids, which required blocking the ear canal and caused significant discomfort when worn for extended periods. In response, bone conduction hearing aids were introduced to the market.

[0003] Bone conduction hearing aids contain an oscillator that transmits sound through bone conduction so that the sound can be perceived by the user. In existing bone conduction hearing aids, the oscillator is often positioned in front of the user's ear, as shown in patents CN309219706S or CN309137761S, where the oscillator is clearly positioned in front of the user's ear.

[0004] However, the bone density in front of the ear is relatively low, and the bone conduction effect is weak. A large part of the sound transmission of this type of hearing aid still passes through the air and enters through the ear canal. This has a very limited effect on users with severe hearing impairment who cannot obtain sound through air transmission.

[0005] On the other hand, the vibrators in commonly used bone conduction hearing aids are often non-replaceable, which is not conducive to matching the size or shape needs of different people and has poor flexibility. Utility Model Content

[0006] The purpose of this invention is to provide a bone conduction hearing aid that can solve one or more of the above-mentioned problems.

[0007] According to one aspect of the present invention, a bone conduction hearing aid is provided, comprising a vibrator and a support. The bracket is equipped with an ear frame, which has a proximal end and a back end. A through hole is provided between the two sides of the back end. The oscillator includes an oscillator body, a pad, and a connecting block. The oscillator body is detachably connected to one side of the back of the ear. One end of the connecting block is connected to the oscillator body, and the other end of the connecting block passes through a through hole and is connected to the pad.

[0008] The beneficial effects of this utility model are as follows: In this utility model, the vibrator is set behind the ear, so that when the user wears this utility model, the vibrator can make contact with the bony protrusion behind the user's ear. The bony protrusion behind the ear has a larger bone density and a better bone conduction effect, which can be more effectively used by users with severe hearing impairment.

[0009] In addition, by separating the pad and connecting block, the oscillator body and the back of the ear can be separated to disassemble the oscillator, making it convenient for users to replace the oscillator to meet the needs of different groups of people, which is highly flexible.

[0010] In some embodiments, the oscillator body has a first protrusion embedded in a through hole and a recess. The pad has a second protrusion embedded in the recess. The first protrusion increases the contact area between the oscillator body and the back of the ear, improving the reliability of the oscillator body's fixation on the back of the ear. Simultaneously, the second protrusion and the recess allow the pad and the oscillator body to be connected in a spliced ​​manner, increasing the contact area between them and improving their connection reliability.

[0011] In some embodiments, a protrusion is provided on the back of the ear, and a groove is provided on the vibrator body, with the protrusion embedded in the groove. The protrusion and groove serve two purposes: firstly, they prevent mistaken installation of the vibrator body in the wrong direction; secondly, they increase the contact area between the vibrator body and the back of the ear, thereby improving the reliability of the vibrator body's fixation on the back of the ear.

[0012] In some embodiments, a protrusion is provided at the back of the ear, and the through hole is located within the protrusion. The protrusion increases the space at the back of the ear, facilitating the installation of the vibrator on the back of the ear.

[0013] In some embodiments, the vibrator body and the pad abut against the two sides of the protrusion, with the pad located on the inner side of the ear frame. The pad's location on the inner side of the ear frame allows for direct contact with the user's head, reducing discomfort.

[0014] In some embodiments, the oscillator includes screws, a first screw hole is provided on the back of the ear, and a second screw hole is provided on the oscillator body. There are multiple screws, first screw holes, and second screw holes. The multiple screws are respectively embedded in the multiple first screw holes and respectively connected to the multiple second screw holes. The screws facilitate the detachment of the oscillator body.

[0015] In some embodiments, the pad and the vibrator body respectively cover both sides of the first screw hole and both sides of the through hole. This avoids exposing the first screw hole and the through hole, improving the aesthetics of the invention, and also hides and protects the screw. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention relates to a bone conduction hearing aid, comprising a vibrator 1 and a support 2.

[0023] The support 2 is provided with an ear frame 21. There can be two ear frames 21, which are symmetrically arranged on the support 2. Each ear frame 21 is provided with a near ear end 211 and a back of the ear 212. The near ear end 211 is located at the end of the ear frame 21, and a protrusion 213 is provided at the back of the ear 212.

[0024] The protrusion 213 is provided with a through hole 214, which passes through both sides of the protrusion 213 on the back of the ear 212.

[0025] The vibrator 1 includes a vibrator body 11, a pad 12, and a connecting block 13. The vibrator body 11 is detachably connected to one side of the protrusion 213 on the back of the ear 212. Preferably, the vibrator 1 also includes screws 14. The back of the ear 212 is provided with a first screw hole 215, and the vibrator body 11 is provided with a second screw hole 111. There are multiple screws 14, first screw holes 215, and second screw holes 111. In this embodiment, there are preferably three screws 14, first screw holes 215, and second screw holes 111. The three screws 14 are respectively embedded in the three first screw holes 215, and the three screws 14 are respectively connected to the three second screw holes 111, so that the vibrator body 11 is connected to the back of the ear 212.

[0026] The connecting block 13 is preferably a stud. One end of the connecting block 13 is connected to the vibrator body 11 by a threaded engagement, and the other end of the connecting block 13 passes through the through hole 214. The other end of the connecting block 13 is also fixedly connected to the pad block 13 by a threaded engagement.

[0027] To improve the fixation reliability of the vibrator body 1 on the back of the ear 212, the vibrator body 1 is also provided with a first protrusion 112, which is embedded in the through hole 214. At the same time, a protrusion 216 is also provided on the back of the ear 212, and the vibrator body 11 is provided with a groove 113, in which the protrusion 216 is embedded.

[0028] In order to improve the connection reliability between the oscillator body 1 and the pad 12, the first boss 112 is also provided with a recess 114, and the pad 13 is provided with a second boss 121, which is embedded in the recess 114.

[0029] The oscillator body 11 and the pad 12, after being set up, abut against the two sides of the protrusion 213 respectively, and the pad is located on the inner side of the ear frame 21. The inner side of the ear frame 21 refers to the side closer to the user's head after the bracket 2 is worn, while the outer side of the ear frame 21 refers to the side away from the user's head after the bracket 2 is worn.

[0030] Furthermore, the spacer 12 and the vibrator body 11, after being set, respectively cover both sides of the first screw hole 215 and both sides of the through hole 214, so as to effectively prevent the first screw hole 215 or the through hole 214 from being exposed, improve the aesthetics of this utility model, and can hide and protect the screw.

[0031] When in use, the bracket 2 can be wrapped around the user's head, and the ear frame 21 can be placed on the user's ear. At this time, the ear end 211 is close to the user's ear canal, and the back of the ear 212 is located on the back of the user's ear. The pad 12 of the vibrator 1 can abut against the bony protrusion behind the user's ear. The bone density here is relatively large, which can effectively ensure the sound bone conduction effect of the vibrator 1, making it more suitable for users with severe hearing impairment.

[0032] When it is necessary to replace the oscillator 1, the user can rotate to separate the pad 12 and the connecting block 13, exposing the screw 14. Then, by removing the screw 14, the oscillator body 11 can be detached from the bracket 2 for replacement. The replaced oscillator 1 can be reattached to the bracket 2 using the screw 14 and reconnected to the pad 12 via the connecting block 13, thus effectively securing the oscillator 1. Therefore, this invention allows users to easily replace the oscillator 1 to meet the needs of different groups, offering high flexibility.

[0033] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
