Abstract

The invention discloses a control method and electronic equipment, wherein the electronic equipment comprises a metal structural part, a sensor chip, a controller and a radio-frequency receiver, wherein the metal structural part is used as a sensing component of a sensor; the sensor chip is connected with the metal structural part, and used for detecting a capacitance value between a human body and the metal structural part; the human body and the metal structural part form two electrodes of a capacitor; the capacitance value is changed with change of the distance between the human body and the metal structural part; the controller is used for generating a control instruction by utilizing the detected capacitance value, and sending the control instruction to the radio-frequency receiver; and the radio-frequency receiver is used for responding to the control instruction and adjusting the conduction power.

Description

technical field [0001] The invention relates to electronic technology, in particular to a control method and electronic equipment. Background technique [0002] Electromagnetic wave energy absorption ratio (SAR, Specific Absorption Rate) is the electromagnetic radiation energy absorbed by human tissue per unit mass and per unit time. The SAR value generally refers to the heat energy generated by electromagnetic waves in electronic devices such as mobile phones, and it is a measure of the impact on the human body. In order to meet the SAR requirements, it is necessary to add detection devices to the electronic equipment, so as to meet the SAR requirements in real time during use. [0003] However, at present, detection devices rely on light signals for detection, which requires that when designing electronic equipment, the detection device needs to be able to sense light in appearance, which will greatly increase the appearance of electronic equipment. ) difficulty. Conte...
