Description

Technical Field

[0001] The utility model belongs to the field of hearing aids, in particular to a bone conduction hearing aid installation structure. Background Art

[0002] Bone conduction hearing aids are an innovative hearing aid device that, unlike traditional air conduction hearing aids, transmit sound directly to the inner ear through the vibration of the skull.

[0003] The biggest difference between bone conduction hearing aids and air conduction hearing aids is that the hearing aid does not need to be inserted into the ear canal. Therefore, for some patients with ear canal obstruction, otitis media, external auditory canal atresia, etc. who are not suitable for using traditional air conduction hearing aids, bone conduction hearing aids provide an effective solution.

[0004] However, the existing bone conduction hearing aids are connected by an elastic band, and there are separate snap-in slots on the left and right ear parts for snapping on the ears, and the elastic band is used to wrap around the back of the user's neck for further stabilization. However, in actual use, not all users need to use both ear parts at the same time. Utility Model Content

[0005] Technical problem to be solved: How to enable users to flexibly choose whether to wear one ear component or both ears at the same time.

[0006] Technical solution: The utility model provides a bone conduction hearing aid installation structure, including a main body component and an adjustment component: the main body component includes two hearing aid bodies, one end of each hearing aid body is connected to a bone conduction connector, and the other end is connected to a cylindrical elastic band, and both ends of the elastic band are connected to elastic balls with a diameter larger than the elastic band; the adjustment component includes a clamping mechanism for clamping the elastic ball, which is arranged on one end of each hearing aid body away from the bone conduction connector; in addition, a tight mechanism is also arranged between the hearing aid body and the elastic band for further clamping and fixing the elastic ball after it is clamped.

[0007] Furthermore, the engaging mechanism includes a spherical groove adapted to the elastic ball and opened at one end of the hearing aid body close to the elastic band, an opening is formed between the spherical groove and the end of the hearing aid body, and the diameter of the opening is equal to the diameter of the elastic band.

[0008] Furthermore, one end of the hearing aid body close to the elastic band is connected to a through-tube whose inner diameter is the same as the opening diameter, and the elastic ball passes through the through-tube and is connected to the spherical groove.

[0009] Furthermore, the tightening mechanism includes an external thread opened on the outer peripheral side of the through-tube, and a plurality of micro grooves distributed in a circular array are also opened through the through-tube, so that it is divided into a plurality of arc-shaped pieces that are not in contact with each other. The outer peripheral sides of the plurality of arc-shaped pieces are jointly sleeved with a sleeve, and an internal thread matching the external thread is opened on the inner wall of the sleeve, so that it can be screwed together with the through-tube.

[0010] Furthermore, the length of the sleeve is equal to the length of the through-tube, and an elastic gasket ring connected to the outer circumference of the through-tube may be provided between the sleeve and the corresponding end of the hearing aid body.

[0011] Technical effect: In the utility model, the two ends of the elastic band are connected to the ends of the hearing aid body through a snap-fit ​​mechanism and are further snap-fitted and fixed through a tight mechanism. That is to say, the elastic band can be separated from the hearing aid body. In this way, the user can choose whether to use the right ear or left ear part alone or connect the two parts together for use according to their own needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0019] The bone conduction hearing aid installation structure provided in this specific embodiment is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a main component and an adjustment component, wherein:

[0020] The main structure includes two hearing aid bodies 1, one end of each hearing aid body 1 is connected to a bone conduction connector 2, and the two parts are composed of one left ear part and the other right ear part; and the other end is connected to a cylindrical elastic band 3, and both ends of the elastic band 3 are connected to elastic balls 4 with a diameter larger than the elastic band.

[0021] The adjustment member includes a snap-fit ​​mechanism for snapping the elastic ball 4, which is arranged at one end of each hearing aid body 1 away from the bone conduction connector 2. The snap-fit ​​mechanism includes a spherical groove 5 adapted to the elastic ball 4, which is opened at one end of the hearing aid body 1 close to the elastic band 3. An opening is formed between the spherical groove 5 and the end of the hearing aid body 1. The diameter of the opening is equal to the diameter of the elastic band 3. In addition, a through-tube 6 with an inner diameter equal to the diameter of the opening is connected to the end of the hearing aid body 1 close to the elastic band 3. The elastic ball 4 is connected to the spherical groove 5 after passing through the through-tube 6. In addition, a tight mechanism 7 for further snapping and fixing the elastic ball 4 after it is snapped is also arranged between the hearing aid body 1 and the elastic band 3. The tight mechanism 7 includes an external thread 701 provided on the outer peripheral side of the tube 6, and a plurality of micro-slots 702 distributed in an annular array are also provided on the tube 6 to divide it into a plurality of arc-shaped pieces that are not in contact with each other. The outer peripheral sides of the plurality of arc-shaped pieces are sleeved with a sleeve 703, and the inner wall of the sleeve 703 is provided with an internal thread 704 adapted to the external thread 701, so that it can be screwed and connected with the tube 6. In this way, since the elastic ball 5 is elastic, it can be compressed through the tube 6 and the opening, enter the ball groove 5 for clamping, and then be screwed with the tube 6 thread through the sleeve 703. Since the tube 6 is divided into a plurality of arc-shaped pieces by the micro-slots 702, the arc-shaped pieces will be squeezed after the spiral connection, so that the arc-shaped pieces squeeze the elastic band 3, which is equivalent to further fixing. In this way, the elastic band 4 can choose whether to connect with the left and right ear parts according to the needs, that is, the left and right ear parts can be used separately or connected together.

[0022] In addition, in order to avoid an uncoordinated protruding structure at the end of the hearing aid body 1 after the elastic band 3 is removed, the length of the sleeve 703 should be equal to the length of the through tube 6, and an elastic gasket connected to the outer circumference of the through tube 6 may be provided between the sleeve 703 and the corresponding end of the hearing aid body 1 to prevent thread slippage. Since the gasket itself is relatively thin, it does not affect the length of the sleeve 703.

[0023] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0024] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
