Abstract

The invention discloses a wireless microphone system that automatically adjusts the transmission power. The power of the microphone signal is detected in real time through a voltage detection module, and the power adjustment signal is transmitted to the wireless microphone transmission circuit through a digital transmission circuit and a digital reception circuit. Adjust the output power of the microphone, when the distance between the microphone and the receiver decreases, reduce the output power of the microphone, and when the distance between the microphone and the receiver increases, increase the output power of the microphone, because the present invention can dynamically adjust the output power of the microphone in real time, It can effectively reduce the power consumption of the microphone and prolong the use time of the microphone.

Description

technical field [0001] The invention relates to a wireless microphone system, in particular to a wireless microphone system which automatically adjusts transmission power. Background technique [0002] At present, for the wireless microphone system, the signal transmission power of the microphone is certain. Since the transmission power is constant, when the distance between the microphone is close enough, the current strong transmission power that is not needed can also meet the requirements of signal transmission, while the wireless The power consumption of the microphone will be very serious when the power is always maintained at high power. The power consumption of the microphone is high and the use time is short. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a wireless microphone system with low power consumption and capable of dynamically adjusting transmission power. [0004] The technical...
