Description

Technical Field

[0001] This utility model relates to the field of hearing aid technology, specifically to a hearing aid device with binaural balance adjustment. Background Technology

[0002] With the aging of society and the increase in the number of people with hearing impairments, the demand for hearing aids continues to grow. Traditional monohearing aids have problems such as sound localization deviation and low speech comprehension, so binaural balance adjustment technology has emerged.

[0003] Existing technologies do not allow for adjustment of the microphone aperture size. A fixed aperture is difficult to adapt to complex environmental changes. In noisy subways or markets, a large aperture allows too much noise to enter, affecting speech clarity. In quiet indoor environments, a small aperture may weaken the normal speech signal, resulting in a softer sound and a less clear hearing. Therefore, we propose a hearing aid device with binaural balance adjustment. Utility Model Content

[0004] The purpose of this invention is to provide a hearing aid device with binaural balance adjustment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hearing aid device with binaural balance adjustment, comprising a housing, ear hooks slidably connected to the housing, and further comprising:

[0006] An adjustment assembly includes a knob mounted on a housing, a connecting rope sleeved on the knob, a microphone hole on the housing, a baffle on the side of the housing near the microphone hole, an extension plate connected to the baffle, and the connecting rope connected to the extension plate.

[0007] A locking assembly includes a connecting plate connected to a knob, a connecting rod connected to the connecting plate, a locking plate rotatably connected to the connecting rod, and a limit plate connected to the side of the housing near the locking plate, the limit plate having a connecting groove.

[0008] Furthermore, a limiting groove is formed on the side of the housing near the baffle, and a limiting block is slidably connected to the limiting groove, with the baffle connected to the limiting block.

[0009] By adopting the above technical solution, the trajectory of the baffle during its movement can be limited by setting a limiting groove and a limiting block.

[0010] Furthermore, the housing is provided with a spring-loaded assembly, which includes a fixing plate connected to the housing, and a spring connecting the fixing plate and the extension plate.

[0011] The above technical solution is adopted: by setting a spring-back component, when the locking component is released, the baffle can automatically spring back to its original position by the elastic force of the spring contraction.

[0012] Furthermore, the housing is provided with a lifting assembly, which includes a slot formed on the housing, a rotating rod rotatably connected in the slot, and a gear connected to the rotating rod.

[0013] The above technical solution is adopted: by setting up a lifting component, the rolling gear can adjust the position of the ear hook on the housing.

[0014] Furthermore, a rack is provided on the side of the ear hook near the gear, and the gear meshes with the rack.

[0015] The above technical solution involves setting a rack that meshes with a gear, so that when the gear rolls, it drives the rack to move.

[0016] Furthermore, the casing is provided with buttons, and a hanging rope is connected between the two buttons. The hanging rope is made of elastic material.

[0017] The above technical solution allows for on / off operation via buttons, and the lanyard design allows it to be worn around the neck.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] In this invention, by setting an adjustment component, the size of the microphone hole can be adjusted to dynamically adapt to different scenarios and user needs. This solves the problem that the size of the microphone hole cannot be adjusted in the prior art, and the fixed aperture is difficult to adapt to complex environmental changes. In noisy subways or markets, a large aperture will allow too much noise to enter, affecting speech clarity; while in quiet indoor environments, a small aperture may weaken the normal voice signal, resulting in a low volume and unclear hearing.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1-5 As shown, this utility model provides a technical solution: a hearing aid device with binaural balance adjustment, including a housing 1, ear hooks 2 slidably connected to the housing 1, buttons 9 provided on the housing 1, and a hanging rope 8 connected between the two buttons 9. The hanging rope 8 is made of elastic material, and also includes:

[0034] Adjustment component 4 includes a knob 41 on the housing 1, a connecting rope 42 on the knob 41, a microphone hole 45 on the housing 1, a baffle 43 on the side of the housing 1 near the microphone hole 45, an extension plate 44 connected to the baffle 43, and the connecting rope 42 connected to the extension plate 44.

[0035] Locking assembly 5 includes a connecting plate 51 connected to the knob 41, a connecting rod 54 connected to the connecting plate 51, a locking plate 55 rotatably connected to the connecting rod 54, and a limit plate 52 connected to the side of the housing 1 near the locking plate 55, and a connecting groove 53 is provided on the limit plate 52.

[0036] Specifically, in a noisy environment, turning the knob 41 causes the connecting rope 42 to retract, which in turn causes the extension plate 44 and the baffle 43 to move, thereby blocking and adjusting the aperture of the microphone hole 45 to reduce the entry of excessive noise. Then, as the knob 41 rotates, it causes the connecting plate 51 to rotate, and the connecting plate 51 causes the connecting rod 54 and the locking plate 55 to be inserted into the communicating groove 53 on the limiting plate 52. Then, turning the locking plate 55 limits the movement.

[0037] Furthermore, such as Figure 4 As shown: A spring-loaded assembly 6 is provided on the housing 1. The spring-loaded assembly 6 includes a fixed plate 61 connected to the housing 1. A spring 62 is connected between the fixed plate 61 and the extension plate 44. In a quiet environment, the locking plate 55 is screwed back to the horizontal direction to cancel the limit in the connecting groove 53. Then the knob 41 is released, and the baffle 43 automatically returns to its original position by the elastic force of the spring 62.

[0038] The above solution also requires that the baffle 43 be limited during its movement, such as... Figure 4 As shown: A limiting groove 7 is provided on the side of the housing 1 near the baffle 43. A limiting block is slidably connected to the limiting groove 7. The baffle 43 is connected to the limiting block. When the baffle 43 moves, it will synchronously drive the limiting block to slide in the limiting groove 7, thereby limiting the movement trajectory of the baffle 43.

[0039] The above solution also has the limitation that the curvature of ear hook 2 should be adjusted according to different users' conditions, such as... Figure 1 As shown: A lifting assembly 3 is provided on the housing 1. The lifting assembly 3 includes a slot 31 opened on the housing 1. A rotating rod 32 is rotatably connected in the slot 31. A gear 33 is connected to the rotating rod 32. A rack is provided on the ear hook 2 near the gear 33. The gear 33 meshes with the rack. The rolling gear 33 drives the rack to move. The rack drives the ear hook 2 to slide and adjust on the housing 1.

[0040] The working principle provided by this utility model is as follows: Figures 1-5As shown: First, the rolling gear 33 drives the rack to move, and the rack drives the ear hook 2 to slide and adjust on the housing 1. Then, the lanyard 8 is hung around the neck. In a noisy environment, the knob 41 is turned to retract the connecting rope 42. The connecting rope 42 drives the extension plate 44 and the baffle 43 to move. When the baffle 43 moves, it will simultaneously drive the limiting block to slide in the limiting groove 7, thereby limiting the movement trajectory of the baffle 43 and blocking the aperture of the microphone hole 45 to reduce the entry of too much noise. Then, when the knob 41 is rotated, it will drive the connecting plate 51 to rotate. The connecting plate 51 drives the connecting rod 54 and the locking plate 55 to insert into the communicating groove 53 opened on the limiting plate 52. Then, the locking plate 55 is turned to limit the movement. In a quiet environment, the locking plate 55 is turned back to the horizontal position to release the limitation from the communicating groove 53. Then, the knob 41 is released, and the baffle 43 automatically returns to its original position by the elastic force of the spring 62.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
