Bone conduction loudspeaker for improving sound leakage

Abstract

The invention discloses a bone conduction loudspeaker for improving sound leakage, and belongs to the field of bone conduction technology. The bone conduction loudspeaker for improving sound leakage comprises a magnet, a coil, a vibrating panel A, a vibrating panel B and an elastic connecting piece; the magnet is arranged on the inner side of the vibrating panel A, the coil is arranged on the inner side of the vibrating panel B, one end of the elastic connecting piece is connected with the vibrating panel A, the other end of the elastic connecting piece is connected with the vibrating panel B, and the vibrating panel A, the elastic connecting piece and the vibrating panel B are connected to constitute a loudspeaker cavity. According to the bone conduction loudspeaker, due to the arrangement of the elastic connecting piece, the sound leakage phenomenon caused by the vibration of the vibrating panels of the bone conduction loudspeaker can be improved; the elastic connecting piece can reduce the mechanical vibration conducted to an external connection fixing point; and the external connection fixing point is used for connecting the bone conduction loudspeaker with an external component and reducing the conduction of the sound leakage vibration of the loudspeaker at the same time.

Description

technical field [0001] The invention belongs to the technical field of bone conduction, in particular to a bone conduction loudspeaker for improving sound leakage. Background technique [0002] Bone conduction converts electrical signals into mechanical vibrations, and the mechanical vibrations are transmitted to the human ear through human tissue to produce hearing; compared with the classic sound conduction method that generates sound waves through the diaphragm, bone conduction saves many steps of sound wave transmission, and can be used in Clear sound reproduction can be achieved in a noisy environment, and sound waves will not affect others due to diffusion in the air. Among them, the bone conduction speaker is a device that converts sound electrical signals into mechanical vibrations. [0003] When the bone conduction speaker is working, it will vibrate, which will drive the surrounding air to emit sound, causing sound leakage. The sound leakage problem of bone conduc...
