Title:
HIGH-EFFICIENCY HEAT DISSIPATION MOBILE PHONE SPEAKER
Document Type and Number:
WIPO Patent Application WO/2017/219340
Kind Code:
A1
Abstract:
The present invention relates to a high-efficiency heat dissipation mobile phone speaker, comprising an internally hollow casing. A first opening communicating with the interior of the casing is formed in the casing, and an internal diaphragm is provided at the first opening; a voice coil working in concert with the diaphragm for sounding is provided in the casing; the casing is also provided with an air inlet, an air outlet, and a heat dissipation plate for separating the first opening from the air inlet; the air inlet and the air outlet are located on the same side of the heat dissipation plate; the heat dissipation plate is provided with a second opening, and a passive diaphragm is provided in the second opening. Providing an air inlet, an air outlet, and a heat dissipation plate facilitates quick heat dissipation by means of air flow, thereby preventing heat from gathering in a speaker. A provided passive diaphragm implements, during operation, heat dissipation by making air flow and effectively improves sound quality while preventing sound distortion. The speaker features an overall simple structure and low costs.
