Device and method for linkage of music and flash light of mobile terminal

Abstract

The invention discloses a device and a method for the linkage of music and a flash light of a mobile terminal. The method comprises the following steps of: firstly, establishing a plurality of levels of brightness control commands from weak to strong according to the brightness of the flash light of the mobile terminal; secondly, establishing a matching relation between sound signal parameters of the music played by the mobile terminal and the brightness control commands according to a scheduled rule; and thirdly, when the mobile terminal plays the music, triggering the brightness control commands according to the resolution of sound signals of the music and according to the matching relation between sound signal parameters and the brightness control commands so as to ensure that the brightness control commands control the brightness of the flash light to change in real time in a range of high-brightness, medium-brightness, low-brightness and turn-off. Thus, when the mobile terminal plays the music, the flash light of the mobile terminal flashes along with the rhythms of the music so that the visual effect of the mobile terminal is greatly enhanced, and the mobile terminal has great marketable values.
