Control circuit of wireless microphone

The utility model discloses a control circuit of wireless microphone, detect the real -time kinetic energy change that IC monitored the microphone through kinetic energy, thereby judge whether the microphone has spatial position's change, and generate kinetic energy change volume data transmission for data processing MCU, during in the long -time inalterability of the real -time kinetic energy ofmicrophone or owing to the free fall rapid change, data processing MCU passes through the size that volume size control circuit control adjusted microphone output volume, not only can be energy -conserving but the condition that can avoid the microphone to utter long and high -pitched sounds appear, experience for the better use of user. 本实用新型公开了种无线话筒的控制电路，通过动能检测IC来监测话筒的实时动能变化，从而判断话筒是否有空间位置的变化，并生成动能变化量数据传输给数据处理MCU，在话筒实时动能长时间不变化或者由于自由落体急剧变化时，数据处理MCU通过音量大小控制电路控制调节话筒输出音量的大小，既可以节能又可以避免话筒啸叫的情况出现，给用户较好的使用体验。
