Wireless digital microphone system

Abstract

The invention provides a wireless digital microphone system comprising a wireless microphone and a wireless receiver, wherein the wireless microphone is composed of a sound receiving module, a sound processing module and a sound transmission module which are connected in sequence; the wireless receiver comprises a sound receiving module, a sound demodulation module, a filtering module and an output module which are connected in sequence; the wireless receiver also comprises an audio processing module and a microcomputer processing module, the audio processing module is a DSP (Digital Signal Processor) audio processor, the microcomputer processing module is a single chip microcomputer unit, and the DSP audio processor and the single chip microcomputer are applied to the sound processing of the wireless digital microphone system to change the sound style. A frequency shifter is applied to the wireless digital microphone system to realize feedback inhibition on screeching. The functional combination of the wireless digital microphone system and an effector is realized, and the functions of network singing, intelligent recording and broadcasting, video exchange, intelligent center control and the like are realized by downloading and installing software from an internet platform. In addition, the system is simple in structure, convenient to operate, low in required cost and good in tone quality.

Description

Technical field [0001] The invention relates to a microphone system, in particular to a wireless digital microphone system. Background technique [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, with complex structure, cumbersome operation and high cost. The adjustment of the microphone by the external device can easily cause the deterioration of the nature of the sound, noise, and affect the sound quality. Conventional wireless microphones cannot update the wireless transmitting and receiving frequencies, download and install software, and have no network switching function. The pursuit of life. Summary of the invention [0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a wireless digital microphone system, which is not only simple in st...
