Abstract

The invention discloses electronic equipment and a signal processing method and device, and belongs to the technical field of sound processing. The electronic equipment comprises piezoelectric ceramic, a microphone module and a digital signal processor, the piezoelectric ceramic is located in a shell of the electronic equipment, the digital signal processor is connected with the piezoelectric ceramic and the microphone module, the piezoelectric ceramic is used for acquiring a first voice signal, and the processor is used for receiving a first voice signal and transmitting the first voice signal to the digital signal processor under the condition that the signal value of the first voice signal is greater than a set signal threshold value, and the digital signal processor is used for carrying out digital signal processing on the first voice signal to obtain a second voice signal.

Description

technical field [0001] The present application belongs to the technical field of sound processing, and more specifically, relates to an electronic device, a signal processing method and a device. Background technique [0002] On current mobile terminals, users have the need to record external sounds. Due to the particularity of the usage scenarios of mobile terminals, no matter what scene the user arrives at, there is a need for sound recording. Therefore, the mobile terminal is required to have a wide range of sound recording, such as Scenes such as voice chat, frog calls on summer nights, concerts, etc. [0003] However, at present, the microphones on mobile terminals are prone to noise in some extreme scenarios, such as high-volume scenes such as concerts and band scenes. The instantaneous sound pressure of these scenes exceeds 120dB, or even exceeds 130dB. Such a large volume range cannot be effectively covered, resulting in noise. Contents of the invention [0004] ...
