Description

Technical Field

[0001] The utility model relates to the field of earphones, in particular to a hearing-aid earphone capable of preventing an M key from loosening. Background Art

[0002] Hearing-assistive headphones are enhanced earphones suitable for people with mild hearing loss. They can perform some of the functions of hearing aids, such as compensating for segmented sound compression. They are primarily designed for people with mild hearing loss caused by long-term use of headphones and listening to music at high volume, or for those experiencing hearing loss with aging. While hearing-assistive headphones can provide some hearing assistance, they differ significantly from hearing aids in terms of function and technology. Hearing aids can be carefully and accurately adjusted based on the individual's specific hearing condition and frequency, meeting various listening needs in different scenarios.

[0003] When using hearing aid headphones for a long time, users often press buttons, among which the M button is used most frequently. Since the M button is prone to falling off after long-term repeated pressing, the user's normal operation cannot be achieved, which greatly reduces the user's usage experience and satisfaction. The M button may also become loose. When the M button becomes loose, the M button becomes extremely sensitive, making it very easy for the user to accidentally press other buttons, thereby causing inconvenience to the user.
