ELECTROACOUSTIC TRANSDUCER

摘要

Disclosed is an electroacoustic transducer, comprising a vibration system and a magnetic circuit system, wherein the vibration system comprises a vibrating diaphragm and a voice coil; and the magnetic circuit system comprises a yoke, a central magnet, and edge magnets; wherein, each edge magnet has a strip shape, limiting parts are provided at two corners of any edge magnet closer to a magnetic gap, and the yoke is provided with stoppers abutted against the limiting parts at positions corresponding to the limiting parts. Each edge magnet of the present invention is provided with limiting parts formed by removing material, and the yoke is provided thereon with stoppers for preventing the edge magnets from approaching the central magnet, so that a bad phenomenon due to the fact that the edge magnets and the central magnet are attracted to each other can be avoided, thereby increasing the yield of a product.

1. An electroacoustic transducer, comprising a vibration system and a magnetic circuit system, wherein the vibration system comprises a vibrating diaphragm and a voice coil combined with the vibrating diaphragm on a lower surface thereof; and the magnetic circuit system comprises a yoke, a central magnet located at central position of the yoke and at a side of the yoke closer to the voice coil, and edge magnets located at edge positions of the yoke, wherein the magnetic circuit system is formed with a magnetic gap to accommodate the voice coil, wherein:
each of the edge magnets has a strip shape, limiting parts are provided on each of the edge magnets at two corners thereof closer to the magnetic gap, the limiting parts are formed by removing materials at the corners of the edge magnets, and the yoke is provided with stoppers, which are abutted against the limiting parts, at positions corresponding to the limiting parts.
