Device for cutting off power supply of microphone and camera and communication terminal

Abstract

The invention relates to a device for cutting off power supply of a microphone and a camera, which is arranged on a communication terminal and comprises a first analog switch and a second analog switch, wherein the first analog switch is provided with a first output end, a second output end, a first control end, a first input end, a second input end, a third input end and a fourth input end; the second analog switch is provided with a third output end, a fourth output end, a second control end, a fifth input end, a sixth input end, a seventh input end and an eighth input end; the first outputend is connected with the microphone power supply end, the second output end is connected with the camera power supply end, the first input end is connected with the microphone power supply end, and the third input end is connected with the camera power supply end; the third output end is connected with the microphone state indicator lamp, the fourth output end is connected with the camera state indicator lamp, the sixth input end is connected with the indicator lamp power supply end, and the eighth input end is connected with the indicator lamp power supply end; and the first control end andthe second control end input the same signal. Power supply of the microphone and the camera can be physically cut off.

Description

technical field [0001] The invention relates to the field of communication terminals, in particular to a device for cutting off power supply of a microphone and a camera and a communication terminal. Background technique [0002] With the development of science and technology, smart phones are becoming more and more common, and our lives are increasingly inseparable from mobile phones. Various applications bring convenience to users, but also bring hidden dangers to safety. Many users do not know In some cases, Trojan horse programs are implanted into your smart phone. These programs will secretly turn on the microphone and camera access rights. Without the user’s knowledge, they will turn on the mobile phone’s microphone to monitor the surrounding sounds and the camera to peek at the surrounding scenes, seriously infringing on the use of The privacy and safety of users, many places prohibit the use of communication devices (mobile phones) or restrict the use of communicatio...
