Abstract

The disclosure relates to a device and method for adjusting radiation power, and electronic equipment. The device includes a first distance sensor, a processor and a modem; the first distance sensor is used to detect whether the user is close to the first distance sensor; the processor is electrically connected to the first distance sensor, and is used to calculate the second distance sensor according to the voltage of the first distance sensor A capacitance variation of the self-capacitance of the distance sensor; the modem is electrically connected to the processor, and is used to adjust the radiation power of the wireless communication module according to the capacitance variation. In this embodiment, the radiation power of the wireless communication module is adjusted by the variation of the capacitance value, which can not only reduce the power consumption of the electronic equipment, reduce the impact of the radiation signal on the user, but also avoid the problem of excessive noise during optical detection in related technologies, which is beneficial to Improve detection and control accuracy.

Description

technical field [0001] The present disclosure relates to the technical field of electromagnetic compatibility, and in particular to a device and method for adjusting radiation power, and electronic equipment. Background technique [0002] With the development of communication technology, electronic devices such as smart phones or smart computers have become indispensable electronic devices in daily life. When using the electronic device, the electronic device needs to establish a communication link with a communication device (such as a base station, a router, etc.) to obtain data (such as a short message, a call, a video), and at this time, the electronic device has relatively large radiation power. For example, when a user makes a call with a smart phone, since the smart phone has established a communication link with the base station, the user is in a strong electromagnetic field at this time, which may affect the health of the user. [0003] In the related art, a distan...
