WIPO Patent Application WO/2019/153762
Kind Code:
A1
Abstract:
Disclosed is a large dynamic multimedia speaker having a large voice coil, comprising a support system, a magnetic circuit system and a vibration system, wherein the support system supports the magnetic circuit system and the vibration system, and the magnetic circuit system is cooperatively installed with the vibration system; the vibration system comprises a voice coil and a body that are cooperatively installed together; the support system comprises a spider used to support the voice coil; and the spider is installed on a spider support frame, the spider support frame is located in the voice coil, and the voice coil is connected to an external ring of the spider. The spider is connected to the voice coil during the reciprocating process of the voice coil, and because the external ring of the spider is connected to an internal ring of the voice coil, the diameter of voice coil may be increased such that a speaker which has a small aperture is provided with a voice coil which has a large diameter and high power, thereby having the effects of high mechanical compliance (cms) and low resonance frequency (fs) and effectively controlling the linear distortion of the speaker.
