Technical Field
[0001] The present invention relates to the field of hearing aids, in particular to a bone conduction hearing aid with adjustable vibrator position. Background Art
[0002] A bone conduction hearing aid is a hearing aid that senses sound based on the vibration of the skull. Conduction is a way of sound transmission, which converts sound into mechanical vibrations of different frequencies and transmits sound waves through the human skull, bony labyrinth, inner ear lymph, cochlear organ, auditory nerve, and auditory center. Since bone conduction hearing aids use the human skull to sense sound, the 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 and air conduction hearing aids are basically the same. They both use microphones to pick up ambient sounds and drive the speakers after processing by digital processors.
[0003] The strap of a bone conduction hearing aid is generally adapted through its own elasticity, but some users have wide necks. The elasticity of the strap of the bone conduction hearing aid will cause the strap to fit tightly against the neck, causing discomfort to the user. At the same time, due to the different sizes and widths of the users' cheeks, the bone conduction hearing aid cannot be well hung on the ear, and the vibrator part will fit against the user's cheek, reducing the effect of the vibrator.
