The projection assembly 4, camera assembly 2, speaker 3, first microphone and second microphone are electrically connected with the controller, the controller includes comparator module and timing module, the comparator module is used to compare the size of the electric signal collected by the first microphone and the second microphone, and the controller is used to control the forward rotation or reverse rotation of the electric control rotating platform 1 according to the comparison result of the comparator module. Figure 3 As shown, the structure specifically includes first microphone, second microphone, amplifier 1, amplifier 2, multivibrator, integrator 1, integrator 2, comparator, controller and electric control rotating platform 1, the first microphone, amplifier 1, multivibrator and integrator 1 are used to process the collected electric signal into direct current signal 1; the second microphone, amplifier 2, multivibrator and integrator 1 are used to process the collected electric signal into direct current signal 2; the comparator compares the direct current signal 1 and the direct current signal 2 and outputs the comparison result to the controller; the controller controls the forward rotation or reverse rotation of the electric control rotating platform 1 through the driving circuit. Among them, the camera assembly 2 adopts a camera, and the camera is connected to the sky net.

[0020] The comparator adopts a hysteresis comparator to improve the stability of the system and avoid the continuous action of the system under high sensitivity conditions. When the camera is aligned with the sound source direction, the difference between the sound signals obtained by the first microphone and the second microphone is small, and no trigger signal is formed, which helps to realize the stable acquisition of the sound source direction camera. For the timing module, the controller can realize information processing, transmission and action selection of the first microphone and the second microphone according to the timing information transmitted by the timing module, such as keeping still for a period of time and then making corresponding actions according to the trigger signal.
