[0002] With the development of modern technology, the technology of hearing aids has been significantly improved. There are various types of hearing aids on the market, among which in - ear hearing aids are the most common. In - ear hearing aids are widely popular because of their small size, inconspicuousness, convenient wearing and effective improvement of sound clarity. However, long - term wearing of in - ear hearing aids also brings some problems that cannot be ignored.

[0003] For consumers with hearing impairments, especially users who need to wear hearing aids for a long time, in - ear hearing aids may cause various adverse reactions. For example, the ear canal is sealed for a long time, which may lead to poor ventilation in the ear canal, thus inducing or aggravating otitis media. In addition, some consumers are allergic to the materials of in - ear hearing aids. After long - term wearing, allergic adverse reactions in the ear canal may occur, such as itching and swelling. These problems not only affect the wearing comfort of users, but may also have a negative impact on their hearing health. Content of the Utility Model

[0024] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.

[0025] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0026] As Figure 1 and Figure 2 As shown, an open Bluetooth hearing aid earphone of the present utility model includes a hearing aid main unit 1. A main control board 10 and a battery 11 are installed inside the hearing aid main unit 1. A microphone is provided on the main control board 10. External sounds are picked up by the microphone and the signals are received by the main control board 10.

[0027] As Figures 1 - 3 As shown, it further includes a sound generating part 2. The sound generating part 2 is connected to the hearing aid main unit 1 through a connecting ear hook 5. A speaker 9 and a sub-board 8 are installed inside the sound generating part 2. The main control board 10 is electrically connected to the sub-board 8 and the wiring is inside the ear hook. The sound picked up by the microphone is processed by the main control board 10 and then transmitted to the wearer by the sound generating part 2. In this embodiment, the entire hearing aid is worn on the ear by using the connecting ear hook 5, which is the same as the wearing method of traditional hearing aids and will not be specifically described here.

[0028] As Figure 2 As shown, an assembly end 6 is provided on the sound generating part 2. The assembly end 6 has a sound hole 7, and an ear tip 13 is detachably installed on the assembly end 6.

[0029] When the ear tip 13 is installed on the assembly end 6, it is an in-ear hearing aid at this time; when the ear tip 13 is removed, it is an external speaker hearing aid at this time. When it is an external speaker hearing aid, only the ear tip 13 needs to be removed, and then the volume of the speaker 9 is increased, and it can be used as an external speaker. The volume is sufficient for the wearer to receive the sound signal.

[0030] Among them, a microphone port 4 is provided on the hearing aid main unit 1. The microphone port 4 is arranged facing the microphone, and the microphone port 4 is provided to improve the microphone effect.

[0031] In order to facilitate the adjustment of the volume playback size, in this embodiment, a volume adjustment button 3 is also provided at the position corresponding to the main control board 10 on the hearing aid main unit. The volume adjustment button 3 can be a touch button, a membrane button, or the like.

[0032] As Figure 2 and Figure 4 shown, an inner side surface of an assembly end 6 of the sound generating part 2 has a card slot 12. A clamping ring 14 is provided at a position corresponding to the card slot 12 on the ear cap 13. The ear cap 13 is inserted into the card slot 12 through the clamping ring 14. The ear cap 13 can be quickly disassembled and assembled by a clamping method. According to the use requirements, the user can install or remove the ear cap 13, making the use more flexible.

[0033] In order to enable the ear cap 13 to be better assembled with the sound generating part 2, increase the assembly contact area, and increase the contact tightness, in this embodiment, the assembly end 6 of the sound generating part 2 is an assembly convex surface, and an assembly concave surface 15 is formed on the ear cap 13 corresponding to the assembly convex surface. The assembly concave surface 15 is positioned and assembled with the assembly convex surface, and the two are more fitted after assembly, and the ear cap 13 is not easily dropped.

[0034] Among them, as Figure 4 shown, a sound transmission channel 16 is provided inside the ear cap 13, and a charging interface is provided on the main control board 10. The battery 11 is charged through the charging interface.

[0035] The present utility model provides an open Bluetooth hearing aid earphone, providing a device that can be used both as an in-ear hearing aid and as an external hearing aid. It can not only effectively improve the otitis media and allergic adverse reactions in the ear canal caused by long-term wearing of in-ear hearing aids, but also provide users with diverse usage options, enhancing the wearing comfort and usage convenience.

[0036] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
