[0003] At present, the wireless functions of most electronic devices for SAR certification include: 2 / 3 / 4G, wifi, Bluetooth, etc., and there are many frequency bands. It is very likely that the SAR will exceed the standard under the initial transmission power, so the hardware design should be equipped with a proximity sensor. After sensing the proximity of the human body, the RF transmission power is reduced to a safe threshold, which also reduces the communication ability of the electronic device

The present disclosure discloses an electronic device and a control method. The electronic device includes: a detection module for detecting a first sensing signal for sensing a target; a monitoring module for monitoring whether the first sensing signal satisfies the first condition ; The radio frequency module is used to generate a first wireless signal when the first induction signal meets the first condition; when the first induction signal does not meet the first condition, generate a second wireless signal, wherein the signal of the first wireless signal The strength is smaller than the signal strength of the second wireless signal; the radiation module is used to radiate the first wireless signal or the second wireless signal. The disclosure can generate a first wireless signal and a second wireless signal with different signal strengths according to the sensing signals that meet different conditions detected by the detection module, and can ensure the communication capability of the electronic device while satisfying the SAR certification test for the electronic device , which improves the user experience.
Description
technical field [0001] The present disclosure relates to the field of electronic technology, in particular to an electronic device and a control method. Background technique [0002] All countries in the world have clear and strict regulations on the radio frequency signal radiation threshold of electronic equipment. Products must undergo SAR (Specific Absorption Rate, electromagnetic wave absorption ratio) certification test when entering the market. [0003] At present, the wireless functions of most electronic devices for SAR certification include: 2 / 3 / 4G, wifi, Bluetooth, etc., and there are many frequency bands. It is very likely that the SAR will exceed the standard under the initial transmission power, so the hardware design should be equipped with a proximity sensor. Sensing the proximity of a human body reduces the power of radio frequency emissions to a safe threshold, which also reduces the communication capabilities of electronic devices. [0004] Therefore, it ...
