ELECTRONIC APPARATUS AND METHOD FOR ACTIVATING SPECIFIED FUNCTION THEREOF

摘要

An electronic apparatus and a method for activating a specified function are provided. The electronic apparatus includes a speaker, an audio signal processor and an application processor. The audio signal processor senses a variation of an acoustic condition of the speaker. The application processor is used for: generating a logic high or low signal in response to the sensed variation of the acoustic condition; interpreting the logic high or low signal as a control signal; and performing an instruction corresponding to the control signal.
