Technical Field

The invention relates to the technical field of speakers, in particular to a bone conduction speaker, a bone conduction earphone and a bone conduction hearing aid.

Background

Bone conduction is a sound conduction mode, namely, sound is converted into mechanical vibration with different frequencies, and sound waves are transmitted through the skull, the bone labyrinth, the lymph fluid transmission of the inner ear, the spiral organ, the auditory nerve and the auditory center of a human body. Compared with a classical sound conduction mode of generating sound waves through a vibrating diaphragm, the bone conduction mode omits a plurality of sound wave transmission steps, can realize clear sound restoration in a noisy environment, and does not influence other people due to the fact that the sound waves are diffused in the air.

The bone conduction speaker technology is used for receiving, sound waves (vibration signals) converted from electric signals are directly transmitted to auditory nerves through bones, and transmission media of the sound waves (vibration signals) are different.

The current bone conduction speaker is generally worn in front of the ear through an ear hoop and conducted into the ear of a person through the ear bone, the U-shaped iron and the magnet are installed inside the bone conduction speaker, the elastic sheet is installed in the gap of the magnet, and vibration is generated between the elastic sheets. The existing wearing mode is usually large in size, and if the loudspeaker is made to be miniature, the size of the magnet is reduced, and the sound wave transmission effect is also poor.
