A light-controlled plasma speaker system

Abstract

The invention discloses an optically controlled plasma loudspeaking 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. The discharge wire is formed by a series of metal pins with mutual air gaps through connection. Laser light is controlled to be irradiated to the corresponding positions on the discharge wire by the PLC. Optically controlled switches between the two adjacent metal pins of the corresponding positions on the discharge wire and the first or second conductive wire are conducted. High voltage of the two ends of the secondary coil of the plasma loudspeaking module is transmitted to the first conductive wire and the second conductive wire and acts between the two metal pins so that high voltage is generated between the two metal pins, air is broken down, and discharge current which generates electric arc, comprises audios and acts as a component sound source is formed. The real omni-directional stereophonic effect can be manufactured by the optically controlled plasma loudspeaking system.

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...

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

[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. 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
