Title:
SPEAKER UNIT
Document Type and Number:
WIPO Patent Application WO/2020/096134
Kind Code:
A1
Abstract:
The present invention relates to a speaker unit. The objective of the present invention is to provide a technique for appropriately controlling a distortion phenomenon of sound signal reproduction by reducing a variation in impedance. A damping member is provided between an armature and a coil to reduce sudden variations of unintended impedance in a particular high-frequency band, thereby relatively flattening an impedance peak of a high-frequency band and thus appropriately controlling the distortion phenomenon of sound signal reproduction, such that clean and fresh sound can be reproduced in a high-frequency band. When the speaker unit receives an external impact, the damping member can absorb the impact, thereby preventing deformation of the armature.
