The microphone and the transmitter are both assembled on the user, and the microphone and the transmitter are connected through an audio line. The transmitter serves as a wireless signal transmitting device of the microphone. The receiver is assembled at the camera end, and the receiver serves as a wireless signal receiving device of the camera for obtaining sound. When sound pickup is performed, the microphone picks up the sound of the user, and the recorded sound is transmitted to the transmitter through the audio line. The transmitter transmits the received sound to the receiver wirelessly. Finally, the receiver directly transmits the sound to the camera for storage.

[0004] Since the microphone for sound pickup needs to be connected to the transmitter through a long audio line, the microphone is usually assembled at the collar of the user's upper garment, and the transmitter is usually assembled at the waist of the user. In order to prevent the audio line from being shot during shooting, the audio line needs to be threaded into the upper garment from the waist and pulled out from the collar to complete the placement of the microphone for sound pickup.
