Title:
REINFORCING PORTION APPLIED TO SPEAKER DIAPHRAGM, DIAPHRAGM, AND SPEAKER
Document Type and Number:
WIPO Patent Application WO/2020/093549
Kind Code:
A1
Abstract:
Disclosed is a reinforcing portion applied to a speaker diaphragm. The reinforcing portion comprises a body layer. The body layer comprises a through-hole passing through surfaces at two sides of the body layer. The reinforcing portion further comprises a filler for heat conduction located in the through-hole. A heat conductivity coefficient of the filler is greater than that of the body layer. In the invention, a support layer of the reinforcing portion is provided with a through-hole, and a filler for heat conduction is provided in the through-hole, thereby improving heat conduction between two sides of the support layer. In a speaker using the reinforcing portion, heat is rapidly conducted from a rear acoustic cavity to a front acoustic cavity, and the front acoustic cavity and an external air flow dissipate the heat to the outside, such that rapid heat dissipation is performed on the speaker.
