Title:
DOME AND LOUDSPEAKER
Document Type and Number:
WIPO Patent Application WO/2022/000611
Kind Code:
A1
Abstract:
The present application relates to the technical field of electroacoustic devices, and in particular to a dome and a loudspeaker. The dome comprises: a first heat dissipation layer and a base material layer which are arranged in a stacked manner, wherein the base material layer comprises a foaming material layer made of a foaming material and a heat conducting material dispersed in the foaming material layer, and the thermal conductivity of the heat conducting material is greater than the thermal conductivity of the foaming material. In the dome and the loudspeaker of the present application, the heat conducting material is provided in the base material layer so that the heat generated by a voice coil can be conducted to a front cavity by heat conducting particles in the heat conducting material in a timely manner and dissipated from the front cavity, thereby improving the heat dissipation efficiency, preventing the composite layer of the dome structure from affecting the acoustic performance of the loudspeaker due to thermal deformation, and improving the stability of the loudspeaker.
