Reverse sound system, also known as "reverse sound" or "reverse sound", is a special type of sound system. Unlike traditional sound systems, it places the main sound emission source in the room where the audience is located, while the sound source is placed in an external space far away from the room. Therefore, the audio signal of the replay sound system is not directly sent to the audience, but is transmitted in reverse through the sound system
Returning audio can provide more realistic and three-dimensional sound effects, which have great advantages in music appreciation, drama performance, movie watching and other occasions:
Realistic sound effects: The echo signal of the surround sound system is more realistic, allowing the audience to experience the improvisation and realistic effects of live performances.
Stereoscopic sound effects: By placing speakers around the listener, the surround sound system achieves a more three-dimensional sound effect, allowing listeners to feel the full range of sound space.
Detailed Photos
The replay audio system mainly consists of the following parts:
1. Speaker: used to emit echo signals, distributed in the room where the audience is located.
2. Microphone: Used to pick up sound from distant sources, placed in the external space outside the room.
3. Main control module: used for processing signals and controlling the dynamic range of the system.
4. Signal processor: can adjust audio parameters such as volume, delay, and harmonic.
5. Signal transmission line: Transmit the audio signal from the microphone to the main control module, and then transmit the echo signal processed by the signal processor to the speaker.
