Description

Bone conduction loudspeaker for inhibiting sound leakage

Technical Field

The utility model relates to a bone conduction loudspeaker technical field, concretely relates to bone conduction loudspeaker of sound leakage of restraining.

Background

Bone conduction is a mode of sound conduction that transmits sound waves through the skull, bony labyrinth, inner ear lymph, spiral organ and auditory center of a person by converting the sound into mechanical vibrations of different frequencies. Compared with the common classical sound conduction mode of generating sound waves through the 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. Current osteoacusis loudspeaker, at the vocal process, because there is the interface in the assembly of loudspeaker, and the support that loudspeaker body and outside support were used is rigid connection, consequently has the sound leakage phenomenon, can influence the tone quality and the amplitude that transmit to the sense of hearing maincenter after the sound leakage is produced. Based on this, the applicant proposed a bone conduction speaker that can suppress sound leakage.
