Protective casing assembly and acoustic wave elimination method

Abstract

The invention provides a protective casing assembly and an acoustic wave elimination method, wherein the protective casing assembly comprises a casing body, a storage battery, a power output interface, an acoustic wave acquisition device, a processor and an acoustic wave output device. The acoustic wave acquisition device and the acoustic wave output device are both disposed on the casing body, and are both electrically connected to the processor. The storage battery is disposed in the casing body and supplies power to an electronic device, the processor, the acoustic wave acquisition device,and the acoustic wave output device. Accordingly, the processor controls the acoustic wave output device to output a second acoustic wave whose phase is opposite to that of a first acoustic wave in order to eliminate the first acoustic wave in the environment where the electronic device is located, thereby solving a technical problem that transmitted and received voice has low intelligibility because the voice function of the electronic device is liable to be affected by environmental noise, and the problem of mobile charging of the electronic device, and improving the convenience of mobile charging of the electronic device and the intelligibility of the transmitted and received voice.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a protective shell assembly and a method for eliminating sound waves. Background technique [0002] With the development of communication technology, the functions of electronic devices are becoming more and more powerful, and users have higher and higher requirements on the voice sending and receiving functions of electronic devices. When a user uses the voice function of an electronic device in a public place, the voice sent and received by the electronic device is easily affected by the noise in the environment, resulting in low intelligibility of the voice heard and uttered by the user through the electronic device. During the use of electronic equipment, the power consumption is relatively large, and the electronic equipment is powered by a fixed charging device or a mobile charging device. Fixed charging devices restrict users to charging electronic devices only at f...
