Description

Technical Field

[0001] This utility model belongs to the field of hearing aid technology, and in particular relates to a novel hearing aid. Background Technology

[0002] With social development and the aging population, hearing aids have become the preferred solution for improving hearing. Currently, the sound transmission channels of hearing aids on the market generally use an aperture of 1.5mm or larger. However, according to actual usage, sound transmission channels with an aperture of 1.5mm or larger can still produce noise during use, thus affecting the wearer's experience. Utility Model Content

[0003] The purpose of this invention is to provide a new type of hearing aid to solve the technical problem of noise that occurs when existing hearing aids are used.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel hearing aid, comprising a hearing aid body and an earphone connected to the hearing aid body, wherein the hearing aid body has a concave surface to fit behind the user's ear, and the earphone has a first sound channel with an aperture of 0.5-1.5mm.

[0005] Furthermore, the earphone is provided with a connecting part for installing earplugs, and the connecting part is provided with a second sound channel, the diameter of the second sound channel being 0.5-1.5mm.

[0006] Furthermore, the aperture of the first sound-emitting channel is 0.8-1.0 mm.

[0007] Furthermore, the aperture of the first sound-emitting channel is 0.9 mm.

[0008] Furthermore, the aperture of the second sound-emitting channel is 0.8-1.0 mm.

[0009] Furthermore, the aperture of the second sound-emitting channel is 0.9 mm.

[0010] Furthermore, the first sound channel and the second sound channel are configured accordingly.

[0011] Furthermore, the connecting part includes a fixed end for connecting with the earphone and a locking end for locking the earplug, the fixed end and the locking end being integrally formed, and the second sound channel passing through the connecting part.

[0012] Compared with the prior art, the present invention has the following advantages through the above technical solution: The present invention reduces the aperture of the sound channel to between 0.5-1.5mm, which is different from the 1.5mm aperture commonly used in the prior art. After the above improvement, the noise can be effectively reduced during use, solving the technical problem that existing hearing aids still produce noise during use, thus affecting the wearer's use.

[0019] The following will refer to the appendix in the embodiments of this utility model. Figure 1-2 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0021] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0022] like Figure 1-2 As shown: A novel hearing aid includes a hearing aid body 1 and an earphone 2 connected to the hearing aid body 1. The hearing aid body 1 is existing technology and will not be described in detail here. The earphone 2 can be freely adjusted relative to the hearing aid body 1. The hearing aid body 1 has a concave surface to fit behind the user's ear. The earphone has a first sound channel 201 with a diameter of 0.5-1.5mm.

[0023] This invention reduces the aperture of the sound-emitting channel to between 0.5-1.5mm, which differs from the 1.5mm aperture commonly used in the prior art. Through the above improvements, noise can be effectively reduced during use, solving the technical problem that existing hearing aids still produce noise during use, thus affecting the wearer's experience.

[0024] like Figure 2 As shown: The earphone 2 is provided with a connecting part 3 for installing an earplug. The connecting part 3 is provided with a second sound channel 301. The diameter of the second sound channel 301 is 0.5-1.5mm. The connecting part 3 is fixedly installed on one side of the earphone 2. The connecting part 3 is provided with a matching custom earplug. The custom earplug is suitable for the ear canal of the hearing aid user and can be detached and replaced according to the user.

[0025] Preferably, the aperture of the first sound-emitting channel 201 is 0.8-1.0 mm.

[0026] Preferably, the aperture of the first sound-emitting channel 201 is 0.9 mm.

[0027] Preferably, the aperture of the second sound-emitting channel 301 is 0.8-1.0 mm.

[0028] Preferably, the aperture of the second sound-emitting channel 301 is 0.9 mm.

[0029] When the aperture of the first sound channel 201 or the second sound channel 301 is 1.3-1.5mm, it can effectively reduce the occurrence of noise compared with the sound channel with an aperture of more than 1.5mm, but there is still a little noise.

[0030] When the aperture of the first sound-emitting channel 201 or the second sound-emitting channel 301 is 0.8-1.0mm, noise can be eliminated and sound can be transmitted smoothly. However, when the aperture of the sound-emitting channel is less than 0.7mm, the sound transmission process is not smooth enough and the transmitted sound is relatively small.

[0031] This invention uses an optimal sound-emitting channel aperture of 0.9mm. When using a sound-emitting channel with an aperture of 0.9mm, not only can noise be eliminated, but the sound transmission process is also smooth and the volume is moderate.

[0032] like Figure 1-2 As shown: the first sound channel 201 and the second sound channel 301 are set accordingly. By setting the first sound channel 201 and the second sound channel 301 that correspond to each other, the sound can be better transmitted. The first sound channel 201 and the second sound channel 301 can be arbitrarily selected within their preferred range.

[0033] like Figure 2 As shown: The connecting part 3 includes a fixed end 201 for connecting with the earphone 2 and a locking end 202 for locking the earplug. The fixed end 201 and the locking end 202 are integrally formed, and the second sound channel 301 passes through the connecting part 3.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
