Abstract

The invention discloses electronic equipment and an audio signal processing method thereof. The electronic equipment in the audio signal processing method of the electronic equipment comprises a shell, a sound production unit and a piezoelectric ceramic piece. The sound production unit is arranged in the shell, the sound production side of the sound production unit is communicated with a sound outlet hole in the shell, and the piezoelectric ceramic piece is arranged on the shell. The processing method comprises the following steps: distributing an audio signal into a first signal and a second signal which are the same; performing first processing on the first signal, and transmitting the processed first signal to a sound production unit; the second signal being subjected to phase reversal processing, time delay processing and gain compensation, and the time delay processing comprising the steps that the time delay duration is calculated according to the position relation of the sound production unit, the piezoelectric ceramic piece and the silencing position, and the processed second signal is transmitted to the piezoelectric ceramic piece; superposing and synthesizing a first sound wave emitted by the sound production unit and a second sound wave emitted by the piezoelectric ceramic piece at the silencing position to be offset.

Description

technical field [0001] The present application belongs to the technical field of audio signal processing methods of electronic equipment, and in particular relates to an electronic equipment and an audio signal processing method thereof. Background technique [0002] The update iteration of smart electronic devices is accelerating, the functions of electronic devices are becoming more and more, and the user's dependence on electronic devices is also increasing. Basically, electronic devices are inseparable from people. How to improve the user experience of electronic devices is an ongoing problem worthy of research. The receiver on the electronic device is the most common part of the call at present. When making a call, the receiver emits a louder sound, which can be heard not only by yourself, but also by other people around, which brings privacy to the call. It is a big problem; but if the sound of the receiver is reduced, it will cause inaudible and so on. Contents of ...
