Abstract

The invention discloses a reinforcing part applied to a diaphragm of a loudspeaker, the diaphragm and the loudspeaker. The reinforcing part is a three-layer composite layer structure. The reinforcingpart comprises a support layer and a first heat dissipation layer and a second heat dissipation layer fixedly bonded to the surfaces on both sides of the support layer. The support layer comprises through holes penetrating the surfaces of both sides of the support layer, and the reinforcing part further comprises a filler for conducting heat located in the through holes, wherein the thermal conductivity of the filler is higher than the thermal conductivity of the support layer. The reinforcing part of the invention improves the heat conductivity between the heat dissipating layers on both sides of the support layer by opening a through hole in the support layer and arranging a heat conductive filler in the through hole.

Description

technical field [0001] The invention relates to the field of electroacoustic technology. More specifically, it relates to a reinforcing portion structure for a loudspeaker diaphragm, and a diaphragm and a loudspeaker to which the reinforcing portion is applied. Background technique [0002] As a component that can convert electrical energy into sound, the speaker is widely used in terminal electronic devices such as mobile phones, tablet computers, notebook computers, and PDAs. The structure of the loudspeaker generally includes a magnetic circuit system, a vibration system and an auxiliary system, and the vibration system mainly includes a diaphragm and a voice coil. When the speaker is working, the voice coil will generate a lot of heat. Since the voice coil is located in the relatively closed rear acoustic cavity of the speaker, the heat generated by the voice coil is not easy to dissipate to the outside world. [0003] Since the front acoustic cavity of the speaker com...
