According to the method of the embodiment, since the electronic device comprises the piezoelectric ceramic, the microphone module and the digital signal processor, the piezoelectric ceramic is located in the shell of the electronic device, and the digital signal processor is respectively connected with the piezoelectric ceramic and the microphone module, after the piezoelectric ceramic picks up the first voice signal, the piezoelectric ceramic transmits the first voice signal to the digital signal processor for digital signal processing under the condition that the signal value of the first voice signal is greater than the set signal threshold value. Generally, when the signal value of the first voice signal is greater than the set signal threshold, it indicates that the piezoelectric ceramic picks up a sound signal with a large volume or an ultra-large volume, and since the sensitivity of the piezoelectric ceramic is low, the piezoelectric ceramic picks up the sound signal with the large volume or the ultra-large volume more optimally, so that noise is not easily generated.

And 6200, performing digital signal processing on the first voice signal through the digital signal processor to obtain a third voice signal when the signal value of the first voice signal is less than or equal to the set signal threshold.
