Description

Technical Field

[0001] The utility model relates to the field of hearing aids, and particularly relates to a glasses-type air-conduction hearing aid. Background Art

[0002] In the design of traditional air-conduction glasses-type hearing aids, the receiver assembly is usually directly placed into the ear canal as an in-ear structure to prevent whistling. This method is similar to the structure of RIC (Receiver-In-Canal, that is, the receiver is placed in the ear canal) or a cassette machine. However, this design is likely to cause the occlusion effect during long-term wearing, and patients may feel uncomfortable. At the same time, due to the complex operation, it is not easy for patients to adjust by themselves, which greatly affects the wearing convenience and comfort of the product. Content of the Utility Model

[0003] Therefore, the utility model provides a glasses-type air-conduction hearing aid to improve the discomfort and inconvenient wearing caused by the need to put the receiver part into the ear in traditional glasses-type air-conduction hearing aids.

[0004] To achieve the above object, the technical solution provided by the utility model is as follows:

[0005] A glasses-type air-conduction hearing aid includes a glasses main body with temple arms and a receiver; an installation cavity is arranged in the temple arms of the glasses main body, and a sound outlet is arranged on the surface of the temple arms and communicates with the installation cavity; the receiver is assembled in the installation cavity of the temple arms, and the sound output part of the receiver is connected to the sound outlet of the temple arms through a rubber hose, so that the sound wave output by the receiver is transmitted out from the sound outlet of the temple arms after being conducted through the rubber hose.

[0006] Further, the temple arms include a front leg part connecting the spectacle frame of the glasses main body and an earrest part connected to the rear end of the front leg part for wearing; the sound outlet is arranged at the rear end of the front leg part.

[0007] Further, the rear end of the front leg part has an inclined surface that is lower than the earrest part and inclines downward, and the sound outlet is arranged on the inclined surface.

[0008] Further, the number of the temple arms of the glasses main body is two, and both temple arms are assembled with the receiver.

[0009] Further, a fixing groove communicating with the sound outlet is also arranged on the inner wall of the installation cavity of the temple arms, and the rubber hose is inserted into the fixing groove.

[0010] Further, the rubber hose is fixed to the temple arms through glue.

[0011] Further, a connecting cylinder is also assembled on the sound output part of the receiver, and the connecting cylinder is fixedly inserted into the rubber hose.

[0012] Furthermore, the temple at least includes a first part and a second part that are detachably separable, and the first part and the second part are assembled and spliced together to jointly form the installation cavity.

[0013] Through the technical solution provided by the present utility model, the following beneficial effects are achieved:

[0014] 1. The receiver is assembled in the installation cavity of the temple. Such a layout not only saves space but also better conforms to the user's wearing habit.

[0015] 2. The sound output part of the receiver is connected to the sound outlet of the temple through a rubber hose, so that the sound wave output by the receiver is transmitted from the sound outlet of the temple after being conducted through the rubber hose; this design ensures that the electroacoustic signal can be stably and efficiently converted into sound. During the sound transmission process, the sound first passes through the rubber hose, appropriately amplifying the high-frequency sound, thereby significantly improving the speech clarity of hearing-impaired patients. More importantly, after the sound is conducted through the rubber hose, it can be more focused and transmitted to the position of the concha cavity, ensuring that the sound can accurately and directly enter the user's ear canal. This focused conduction method not only improves the sound clarity but also further enhances the wearing comfort. BRIEF DESCRIPTION OF THE DRAWINGS
