Description

Technical Field

[0001] The utility model relates to the field of hearing aid earphones, in particular to a shock-absorbing hearing aid earphone. Background Art

[0002] Hearing-assistive headphones, also known as hearing-enhancement headphones or hearing-assistive devices, are devices designed to improve the hearing of people who are hard of hearing or have hearing loss. These headphones are designed to amplify sound and reduce background noise to make it easier for the wearer to hear conversations or other sounds. Hearing-assistive headphones are usually connected to a microphone that is placed near the source of the conversation or other sound. The microphone picks up the sound and sends it to the headphones, which amplify the sound and transmit it to the wearer's ears. These headphones may have different functions, such as adjusting the amplification level, reducing background noise, or synchronizing multiple microphones to provide clearer sound quality. For the existing increasingly mature hearing-assistive headphones, being satisfied with the hearing-assistance function alone can no longer meet the increasing demand of users for the comfort of hearing-assistive headphones. Therefore, improving the comfort of hearing-assistive headphone users has become the improvement direction of current headphones. In the prior art, there are the following problems:

[0003] In the existing hearing aid earphone technology, due to the small internal space of the earphone, the speaker (the sound amplifier module) is too close to other functional modules such as the circuit board. When the speaker vibrates, the entire earphone vibrates. This greatly reduces the comfort of the hearing aid earphone. More seriously, due to the close proximity to the circuit board, the circuit board is often hit by the speaker, which increases the probability of circuit board failure. Utility Model Content
