Description

Technical Field

[0001] This utility model relates to an external microphone RIC hearing aid, belonging to the field of RIC hearing aid technology. Background Technology

[0002] Currently, the most common hearing aids on the market are body-worn, behind-the-ear, and custom-made. Due to intense market competition and higher customer demands, RIC hearing aids have gradually been introduced. These hearing aids are more discreet, compact, and aesthetically pleasing. They generally consist of a hearing aid unit and a receiver, which are connected by a conduit.

[0003] Existing receivers generally have a mushroom-shaped tip and a cerumen mesh. When the receiver is pushed into the ear canal, the mushroom-shaped tip is pushed into the inner end of the ear canal, resulting in a poor user experience. In addition, the cerumen mesh can become clogged during use, requiring regular cleaning by a professional, which leads to high after-sales costs. To address the above problems, this utility model proposes an external microphone-based RIC hearing aid. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an external microphone RIC hearing aid to solve the existing problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an external microphone RIC hearing aid, the structure of which includes a hearing aid body, on which a thin wire is electrically connected, and the other end of the thin wire is electrically connected to an external receiver. The external receiver includes a housing, and a speaker body that is electrically connected to the other end of a thin wire is fitted inside the housing cavity. The top surface of the housing is covered with a cover for pressing and fixing the speaker body. Both the housing and the cover are made of plastic.

[0006] A further improvement is that a groove for the speaker body to fit into is provided in the middle of the top surface of the outer shell, and a through hole is provided on the right wall of the groove, and a bottom pressure seat is provided in the left cavity of the groove. Multiple retaining edges are provided on the front and rear walls of the groove.

[0007] A further improvement is that a first sound channel is provided on the left side wall of the sleeve groove, and the first sound channel has an inverted L-shaped structure. A second sound channel is provided horizontally through the lower end of the outer shell and is connected to the first sound channel. The second sound channel is a straight channel. A through hole is provided vertically on the left side of the top surface of the outer shell and is connected to the upper end of the first sound channel.

[0008] A further improvement is that a plug is nested on the right end of the second audio channel, and the plug is made of rubber.

[0009] A further improvement is that the cover includes a cover plate, and the bottom of the cover plate has symmetrically arranged corners at both ends for engaging with the locking edge, and a top pressure seat is provided at the left end of the bottom surface of the cover plate.

[0010] A further improvement is that the hearing aid body and the speaker body are both existing technologies, and their structures will not be described in detail here.

[0011] The beneficial effects of the utility model are: This utility model provides an external microphone-type RIC hearing aid. The external receiver, consisting of a shell, a speaker body, and a cover, eliminates the need for a mushroom-shaped head and a cerumen mesh. This allows users to insert the external receiver into the ear canal without the mushroom-shaped head blocking the ear, resulting in a more natural and comfortable fit and a better user experience. The external receiver features a staggered connection between the first and second channels, which are the main areas of cerumen blockage. The second channel is a straight channel, while the top surface of the first channel has an auxiliary through-hole. This allows users to easily clean the cerumen by using a bristle handle for horizontal and vertical cleaning, making the operation simple and efficient. It eliminates the need to disassemble the external receiver, avoiding after-sales cleaning costs and demonstrating strong practicality. Attached Figure Description

Detailed Implementation

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] Please see Figure 1-6The present invention relates to a schematic diagram of an RIC hearing aid with an external microphone: its structure includes a hearing aid body 1, on which a thin wire 2 is electrically connected, and the other end of the thin wire 2 is electrically connected to an external receiver 3. The external receiver 3 includes a shell 31, and a speaker body 32 that is electrically connected to the other end of the thin wire 2 is housed inside the cavity of the shell 31. The top surface of the shell 31 is covered with a cover 33 for pressing and fixing the speaker body 32. Both the shell 31 and the cover 33 are made of plastic.

[0015] The top surface of the outer shell 31 has a groove 311 for the speaker body 32 to be fitted into. A through hole 312 is provided on the right groove wall of the groove 311, and a bottom pressure seat 313 is provided in the left groove cavity of the groove 311. Multiple retaining edges 318 are provided on the front and rear groove walls of the groove 311.

[0016] A first sound channel 314 is provided on the left side wall of the sleeve groove 311. The first sound channel 314 has an inverted L-shaped structure. A second sound channel 315 is provided horizontally through the lower end of the outer shell 31, which is connected to the first sound channel 314. The second sound channel 315 is a straight channel 315. A through hole 316 is provided vertically on the left side of the top surface of the outer shell 31, which is connected to the upper end of the first sound channel 314.

[0017] A plug 317, made of rubber, is nested on the right end of the second sound channel 315.

[0018] The cover 33 includes a cover plate 331, and the bottom end of the cover plate 331 is symmetrically provided with locking corners 332 that hook with the locking edge 318, and the left end of the bottom surface of the cover plate 331 is provided with a top pressure seat 333.

[0019] Working principle: When wearing the hearing aid, the user pushes the external receiver 3 into the ear canal. At this time, the second channel 315 will be aligned with the ear canal. Then, the hearing aid body 1 is hung behind the ear and the position is adjusted until it fits comfortably without any foreign body sensation. This is the standard wearing procedure and will not be described in detail.

[0020] When in use, external sounds are received, processed and amplified by the hearing aid body 1 and then transmitted to the sound output body 32 through the thin wire 2. The sound will enter the ear canal through the first sound channel 314 and the left end of the second sound channel 315. It should be noted that the through-hole 316 will be blocked by the ear canal wall during use, and the outer end of the second sound channel 315 will be blocked by the plug 317 to prevent the sound from spreading outward.

[0021] After the external receiver 3 has been used for a period of time, cerumen will block the left end of the second channel 315 and the lower end of the first channel 314. Because the second channel 315 and the main body 32 of the speaker are designed to be offset vertically, the cerumen will not block the main body 32 of the speaker itself. When cleaning the cerumen, the user uses a burr to push the cerumen to the right through the second channel 315 from left to right, and at the same time pushes down the plug 317 to achieve the external discharge of the cerumen. The cerumen at the lower end of the second channel 315 is pushed into the second channel 315 through the burr through the plug hole 316. Repeating this several times can completely clean the lower end of the first channel 314 and the cerumen in the second channel 315.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
