Description

Technical Field

[0001] The present invention relates to the field of hearing aids, in particular to a bone conduction hearing aid. 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] Bone conduction hearing aids are generally hung on one side of the ear, but the distance and size of the ears of different people are different. Some bone conduction hearing aids cannot adjust the position of their own vibrators when in use. When the vibrators are in use, they may not be able to fit closely with the user's ears, reducing the use effect. At the same time, the shells of some bone conduction hearing aids are connected by buckles. When repairing the internal components, disassembly is cumbersome, which increases the repair time. Therefore, it is necessary to propose a bone conduction hearing aid. Summary of the invention
