Title:
REINFORCING PART APPLIED TO DIAPHRAGM OF LOUDSPEAKER, AND DIAPHRAGM AND LOUDSPEAKER
Document Type and Number:
WIPO Patent Application WO/2020/093550
Kind Code:
A1
Abstract:
Disclosed in the present invention is a reinforcing part applied to a diaphragm of a loudspeaker, wherein the reinforcing part is a multi-layer composite layer structure and comprises a heat dissipation layer and a first support layer and a second support layer that are respectively fixedly combined on two side surfaces of the heat dissipation layer; the first support layer and the second support layer both comprise through holes penetrating through the two side surfaces thereof; and the reinforcing part further comprises a filler for thermal conductivity that is located in the through hole, and the thermal conductivity of the filler is higher than the thermal conductivity of the support layer. The reinforcing part of the present invention improves the thermal conductivity between two side surfaces of the reinforcing part by providing the through holes in the first and second support layers, and providing a thermally conductive filler in the through hole. The loudspeaker having the reinforcement structure can quickly conduct heat from a rear sound cavity to a front sound cavity, and then radiate the heat to the outside by means of the flow of the front sound cavity and the outside air, so as to perform quick heat dissipation on the loudspeaker.
