Problems solved by technology

[0002] At present, most voice monitoring methods need to pre-install voice sensing devices such as microphones indoors. Since the sensing head needs to be installed indoors, it is necessary to have a pre-judgment of the room where the person to be monitored will live. At the same time, the sensing device installed indoors Easily exposed, poses risks

Abstract

The invention discloses equipment and a method for voice monitoring. The equipment for voice monitoring comprises a mechanical vibration sensing module and a signal processing module. The mechanical vibration sensing module is used for sensing signals of mechanical vibration of walls, floors or solid attachments of the walls and floors caused by original voice and converting the mechanical vibration signals into electric signals. The signal processing module is connected with the mechanical vibration sensing module, and used for restoring the original voice from the electric signals. A sensor does not need to be mounted indoors in advance for acquiring voice signals so that possibility of exposure is reduced, and monitoring position can be changed anytime since the method is high in activity.

Description

technical field [0001] The invention relates to the technical field of monitoring in the electromechanical industry, in particular to a device and a method for performing voice monitoring by using the mechanical vibration of a wall or other objects caused by voice. Background technique [0002] At present, most voice monitoring methods need to pre-install voice sensing devices such as microphones indoors. Since the sensing head needs to be installed indoors, it is necessary to have a pre-judgment of the room where the person to be monitored will live. At the same time, the sensing device installed indoors Easy to expose and bring risks. Contents of the invention [0003] (1) Technical problems to be solved [0004] In order to solve one or more of the above problems, the present invention provides a device and method for performing voice monitoring by utilizing the mechanical vibration of a wall or other objects caused by voice, so as to improve the effectiveness of the v...
