Abstract
(EN)
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.

La présente invention concerne une partie de renforcement appliquée à un diaphragme d'un haut-parleur, la partie de renforcement étant une structure de couche composite multicouche et comprenant une couche de dissipation de chaleur et une première couche de support et une seconde couche de support qui sont respectivement combinées de manière fixe sur deux surfaces latérales de la couche de dissipation de chaleur; la première couche de support et la seconde couche de support comprennent toutes deux des trous traversants pénétrant à travers les deux surfaces latérales de celle-ci; et la partie de renforcement comprend en outre une charge pour la conductivité thermique qui est située dans le trou traversant, et la conductivité thermique de la charge est supérieure à la conductivité thermique de la couche de support. La partie de renforcement de la présente invention améliore la conductivité thermique entre deux surfaces latérales de la partie de renforcement en fournissant les trous traversants dans les première et seconde couches de support, et en fournissant une charge thermoconductrice dans le trou traversant. Le haut-parleur ayant la structure de renforcement peut conduire rapidement de la chaleur d'une cavité sonore arrière à une cavité sonore avant, et rayonne ensuite la chaleur vers l'extérieur au moyen du flux de la cavité sonore avant et de l'air extérieur, de façon à effectuer une dissipation thermique rapide sur le haut-parleur.

本发明公开一种应用于扬声器振膜的补强部,所述补强部为多层的复合层结构,该补强部包括散热层以及分别固定结合于所述散热层两侧表面的第一支撑层和第二支撑层,所述第一支承层和第二支承层上均包括有贯穿其两侧表面的通孔,所述补强部还包括有位于所述通孔内的用于导热的填充物,所述填充物的导热系数高于所述支承层的导热系数。本发明的补强部通过在第一支承层和第二支承层上开设通孔,并在该通孔内设置导热的填充物,提高补强部两侧表面之间能够导热能力。采用此种补强部结构的扬声器可将热量从后声腔中快速传导到前声腔中,进而通过前声腔与外界空气的流动,将该热量向外散发,从而对扬声器快速散热。
