Problems solved by technology

[0005] However, the UHF wireless microphones in the prior art have poor balance and cannot diversify the sound styles of the wireless microphones.
In practical applications, since each person's voice has its own characteristics, and each region, each person has different preferences for sound and sound quality effects; in addition, there are many types of peripheral supporting equipment, and the parameters are different. The sound quality of the microphone is not enough to meet the requirements of most people
In addition, general UHF wireless microphones cannot be controlled by wireless remote control

Description

technical field [0001] The invention relates to the technical field of wireless microphones, in particular to a UHF multifunctional wireless microphone. Background technique [0002] Wireless microphone or wireless microphone, also called microphone wireless microphone, wireless microphone is an audio equipment that transmits sound signals, and consists of two parts: a transmitter and a receiver. [0003] The working principle of the wireless microphone system is: the transmitter is powered by a battery, and the microphone converts the sound into an audio electrical signal. After processing by the internal circuit, it transmits radio waves containing audio information to the surrounding space. The receiver is generally powered by the mains. The radio wave from the transmitter is received by the receiving antenna. After processing by the internal circuit, the audio signal is extracted and sent to the sound reinforcement system through the output signal line to complete the wi...
