Abstract

The invention discloses an electroacoustic transducer. The electroacoustic transducer comprises an oscillating system, a magnetic circuit system, and a shell for accommodating and fixing the oscillating system and the magnetic circuit system, wherein the oscillating system comprises an oscillating diaphragm and a voice coil which is jointed on one side of the oscillating diaphragm; the shell has a metal structure; the electroacoustic transducer further comprises a centering disk which is jointed with the oscillating system; a hard reinforcing part is arranged on the edge of the centering disk; a welding pad and a circuit for electrically connecting the welding pad and the centering disk are arranged on the reinforcing part; the voice coil comprises a voice coil lead; and the voice coil lead is electrically connected with the centering disk. By adopting the structure, the oscillating diaphragm can be protected from polarization; and an operating process for electrically connecting with an external circuit is simple.

Description

technical field [0001] The invention relates to the field of electroacoustics, in particular to an electroacoustic transducer. Background technique [0002] In the prior art, the electro-acoustic transducer includes a vibration system, a magnetic circuit system, and a housing that accommodates and fixes the vibration system and the magnetic circuit system; usually, the internal circuit of the electro-acoustic transducer communicates with the external circuit through an electrical connection assembly .
