Light Control Stereo System

Abstract

The invention discloses a light-operated stereophonic sound system which comprises a plasma loudspeaking module, a PLC (Programmable Logic Controller), a first wire, a second wire and a discharge wire. The first wire, the second wire and the discharge wire are laid in parallel at the positions, where music needs to be generated, in the space; the first wire and the second wire are respectively and electrically connected with one output end of a secondary coil of the plasma loudspeaking module; light-operated switches are conducted when being irradiated by hard light; the PLC controls an illuminating system; the illuminating system is a controllable laser lamp; the PLC enables the light-operated switch corresponding to the random position on the discharge wire to be conducted at any moment by a preset program; the controllable laser lamp is provided with more than one lamp cap; all lamp caps are peripherally and uniformly distributed. According to the light-operated stereophonic sound system, the positions of sound sources can be controlled at will on a circuit where the discharge wire is laid, so that music generates various flowing and drifting effects and a real omnibearing stereophonic sound effect is created.

Description

technical field [0001] The present invention relates to the field of electronic audio systems, in particular, to the field of plasma speaker systems. Background technique [0002] Plasma speakers are a type of speakers, but they are completely different from ordinary speakers. Ordinary speakers use the vibration of the diaphragm to drive the air to produce sound. Since each diaphragm has its own resonance frequency, it is inevitable that the amplitude and frequency of the sound will be reduced. Deterioration of characteristics - the components in the audio signal whose frequency is close to the resonance frequency of the diaphragm are the strongest, while those components whose frequency is far away from the resonance frequency will attenuate, the farther away the more the attenuation will be, and finally it will be completely attenuated. It can be seen that if you want to improve The sound generation performance of ordinary loudspeakers must solve the resonance problem of t...

However, for this ideal sound effect, according to the current technology, it can only stay in the imaginary world. Even the most advanced and expensive speaker equipment and sound effect processing technology can only produce some simple sound illusions through electronic simulation. The above-mentioned free-wheeling stereo flow sound effect cannot be realized at all

[0006] In view of the aforementioned reasons, the applicant has applied for an invention patent named "Full Controllable Flow Surround Sound System" on January 12, 2013, with the application number 2013100106529, which provides a The surround sound system can produce free-flowing sound effects. However, in this patent application, due to the use of a large number of electronic switches, and in the specific implementation mode, it is only pointed out that the control of each electronic switch is realized through the control line. Therefore, in In the actual layout, a large number of control lines need to be additionally arranged, which not only makes the construction troublesome, but also easily causes signal interference between the control lines. However, no superior technical solution has been given for the control problem of the stereo system
