Document Type and Number:
WIPO Patent Application WO/2018/170946
Kind Code:
A1
Abstract:
Disclosed is a moving magnet loudspeaker, relating to the technical field of electroacoustic products, and comprising an enclosure, wherein the enclosure houses a diaphragm and a voice coil arranged parallel to the diaphragm under the diaphragm; the diaphragm comprises a surround with an edge part fixed on the enclosure, a middle part of the surround is provided with a vibrating plate, a driving magnet is fixed to one side of the vibrating plate near the voice coil; an armature is provided in a centre hole of the voice coil, the armature is arranged opposite the driving magnet and spaced apart from the driving magnet, the voice coil forms an electromagnet after electrification, generating an interaction force with the driving magnet such that the driving magnet moves, thereby driving the diaphragm to vibrate. The moving magnet loudspeaker of the present invention solves technical problems in the prior art such as the high frequency transient response of moving coil loudspeakers being poor, improving the high frequency transient response, while the resonance frequency is relatively low, sensitivity is good, and overall performance is high, meeting the performance requirements of Hi-Fi equipment.
