Problems solved by technology
[0002] Conventional wireless microphones have only one fixed sound style, which is difficult to meet different usage requirements and adapt to different usage environments. It needs to rely on external equipment to adjust the sound style. The structure is complex, the operation is cumbersome, and the cost is high.
However, the adjustment of the microphone by external equipment can easily cause deterioration of the sound quality, noise, and affect the sound quality. Conventional wireless microphones cannot be updated to update the wireless transmission and reception frequencies, and cannot download and install software. pursuit of life
