Light-operated stereophonic system

Abstract

The invention provides a light-operated stereophonic system which comprises a plasma loudspeaking module, a PLC, a first leading wire, a second leading wire and a discharge wire. The first leading wire, the second leading wire and the discharge wire are paved in parallel. The first leading wire and the second leading wire are respectively and electrically connected with an output end of a secondary coil of the plasma loudspeaking module. The discharge wire is formed by the fact that a series of metal bodies provided with air intervals are clustered. Pointed cones are arranged at two ends of each metal body. Parts of the metal bodies are electrically connected on one of the first leading wire and the second leading wire, and parts of the metal bodies adjacent to the parts are electrically connected on the other one of the first leading wire and the second leading wire. Each metal body is electrically connected with the first leading wire or the second leading wire through a light-operated switch. The light-operated switch is turned on when being lighted by strong light. The PLC controls a lighting system so that the lighting system can generate lighting on each portion of the discharge wire. The light-operated stereophonic system can create free flowing surround sound effect, control is easy, and atmosphere rendering effect is further enhanced.

Description

[0001] technical field [0002] The present invention relates to the field of electronic audio systems, in particular, to the field of plasma speaker systems. [0003] Background technique [0004] 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 res...

Problems solved by technology

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

[0008] 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. Therefore, although the applicant has proposed a mobile stereo system composed of plasma speakers, but For the control problem of the stereo system, no superior technical solution is given
