Abstract

This disclosure is about apparatus and method of cell phone sound management to avoid privacy leak and enhance talking in public circumstances. It includes a back side sound receiver which can collect sounds from surrounding environment and obtain the band width of the environment noise, a talking side sound receiver which can collect talking sound when people answer a call and obtain the band width of the talking person, a talking enhancer which can filter the environment noise from the talking sound and enhance talking, an environment noise enhance which can filter the talking environment and enhance environment noise, an adaptive sound wave inverter which can generate sound signal with the same amplitude as the talking sound while with the anti-phase from it and adaptively adjust its parameter with the attenuated talking sound, a emitter which can emit the generated anti talking sound generated by the adaptive sound inverter.
