Problems solved by technology

[0005] The defect of the switching mode of this prior art is that there are many kinds of Trojan horse / hacker software in reality, and the switching of the integrated device controlled by the software mode is vulnerable to attack, which cannot bring a sense of trustworthiness to the user
[0009] To sum up, in the prior art, there is no effective management and control means for the recording of the microphone integrated in the data processing device and the shooting of the camera
[0010] In addition, the same problem exists for the infrared input circuit inside the data processing equipment

Embodiment Construction

[0039] Please refer to FIG. 3 , which is a schematic diagram of a first embodiment of the switch unit of the integrated device of the present invention.

[0040] This first embodiment applies to prohibition and permission of microphone use.

[0041] The microphone 100 has two pins T1 and T2. The vibration of the sound wave will form a voltage between the pins T1 and T2, which is coupled to the input point A of the sound card chip 120 through the capacitor C. The sound card chip 120 generally uses an A / D A converter (not shown) converts it into a digital signal.

[0042] In order to realize the management of the working state of the microphone, a first switch K1, a second switch K2 and a third switch K3 are provided. Wherein, the first switch K1 is set between the pins T1 and T2, the second switch K2 is set between the input point A of the sound card chip 110 and the ground, and the third switch K3 is set between the pin T1 and the input point of the sound card chip 110 Betwe...

Abstract

A switch unit of integration device of data processing equipment is disclosed, the switch unit is mounted on the optical access, acoustics access or electrical source access of integration device, the working state of integration device is controlled by disconnection or connection by mechanical mode. The integration device can be microphone, CCD camera and / or sensing circuit and so on. The switch unit chooses the mechanical switch, electric switch or shading device according to the request. The invention can realize the management and controlling for the working state of integration device.

Description

technical field [0001] The invention relates to the control technology of the external sensing device of the data processing equipment, in particular to a switch unit of the integrated device of the data processing equipment. Background technique [0002] With the development of information technology, people are increasingly exposed to various electronic data processing devices, such as notebook computers and mobile phones. [0003] At present, in order to meet people's requirements for information collection and transmission in daily life, work and study, there are more and more data processing devices integrating audio and video collection devices (such as microphones, cameras, etc.), so that people can better Enjoy the process of video chatting or recording / photographing freely. Usually, in a data processing device (such as a notebook, a mobile phone, etc.), the microphone is exposed to the outside, and the camera is also directly exposed to the outside. [0004] In th...
