Abstract

This invention discloses an anti-electromagnetic interference bone-conduction speaker, and a manufacturing method thereof. A magnet system consists of a magnet baseplate, a permanent magnet, a balance armature, a pivot, a magnetic conductive plate, a coil and a vibrating diaphragm; the balance armature fixed on the pivot can be moved; the balance armature can move in a permanent magnetic field; when current passes through the coil, the balance armature is magnetized on a single way or a reverse way; the balance armature moves under the effect of the magnetic force to cause air movements, so that the vibrating diaphragm vibrates; the vibrating diaphragm is connected with a vibration transmission piece through a vibration transmission spring; the vibration transmission piece is connected with the panel through the vibration transmission spring; the bone-conduction speaker is connected with the exterior through the panel, so that the vibration can be transmitted to human bones to generate sounds; a flexible graphite is arranged at the inner side of the main body of the speaker to prevent electromagnetic interference and reduce noise. By adoption of a closed structure, the speaker is not interfered by external environment factors; the sound is clear and free of noise; and a user will not feel giddy when using the speaker for a long time.

Description

technical field [0001] The invention relates to the technical field of bone conduction speakers, in particular to a method for manufacturing an anti-electromagnetic interference bone conduction speaker. Background technique [0002] In the prior art, the principle of hearing sound is that the vibration in the air transmits the vibration to the eardrum through the external ear canal, and the vibration formed by the eardrum drives the human auditory nerve, thereby perceiving the vibration of sound. When the existing bone conduction loudspeaker works, it usually transmits to the human auditory nerve through the human skin, subcutaneous tissue and bone, so that the human can hear the sound. When the existing bone conduction speaker works, along with the vibration of the vibration plate, the housing on which the vibration plate is fixed via the fixed block also vibrates along with the vibration plate, so the vibration surface of the housing is in contact with the back of the ear,...
