Abstract

The invention discloses an optically controlled stereophonic system comprising a plasma loudspeaking module, a PLC, a first conductive wire, a second conductive wire and a discharge wire. The first conductive wire, the second conductive wire and the discharge wire are laid in parallel in the position of space requiring music generation. The first conductive wire and the second conductive wire are electrically connected with one output end of the secondary coil of the plasma loudspeaking module respectively. Optically controlled switches are conducted when receiving high light irradiation. The PLC controls a lighting system which is an LED lamp bar parallel with the discharge wire in arrangement. The lighting mode of the LED lamp bar is controlled by the PLC so that any points or line segments on the LED lamp bar are enabled to emit light any time to irradiate the discharge wire and the corresponding optically controlled switches are enabled to be conducted, and thus sound generation of the positions corresponding to any points or the line segments on the discharge wire is realized. The controllable LED lamp bar is quite popular so that construction cost is low and controllability is high.
