In smart mobile phone design, usual loudspeaker and receiver are discrete designs, and the power of ventional loudspeakers is non-
It is often low, main board region about is mainly derived from 200mW or so, the too high and caused amount of heat of its complete machine temperature, current solution
Certainly the method for temperature rise radiating is to realize the radiating to main board region by heat sink material substantially, and for loudspeaker,
The underproof situation of temperature rise will not be run into substantially because power is relatively low, while again because discrete designs, the hot zone with mainboard
Domain is generally a good distance away, and the environment of temperature rise is also ideal.Furthermore go out acoustic aperture and the contact pad of loudspeaker are generally all
On two sides, which also limits the design of speaker portion heat sink conception.
