Description

Technical Field

[0001] The present invention relates to the field of hearing aids, in particular to a bone conduction hearing aid which is easy to maintain. Background Art

[0002] A bone conduction hearing aid is a hearing aid that senses sound based on the vibration of the skull. Since bone conduction hearing aids use the human skull to sense sound, aging or disease of the auditory organ generally does not affect sound conduction, and the hearing aid effect is often better. The principles of bone conduction hearing aids are basically the same as those of air conduction hearing aids. Both use microphones to pick up ambient sounds and drive the speakers after processing by a digital processor.

[0003] When installing some bone conduction hearing aids, the diaphragm and the pickup are generally directly glued to the shell with glue. When the diaphragm and the pickup are damp or damaged by external force, the diaphragm and the pickup need to be repaired. However, the diaphragm and the pickup glued together are not convenient for quick disassembly. At the same time, the glue will adhere to the shell or the outer wall of the diaphragm and the pickup and cannot be cleaned, which affects the reinstallation of the diaphragm, the pickup and the shell. Therefore, it is necessary to propose a bone conduction hearing aid that is easy to repair. Summary of the invention
