Remote intelligent control system for musical instrument loudspeaker

Abstract

The present invention relates to the technical field of loudspeaker control systems and particularly relates to a remote intelligent control system for musical instrument loudspeaker. The remote intelligent control system comprises a communication system, a remote control end, a power amplifier system, a low-pass filter circuit, a protection circuit, a bus system, and a central processing system. The power amplifier system is used for amplifying a weak signal from a sound source or a preamplifier, the signal is converted by the central processing system and then is transmitted to the remote control end through fiber communication, and the remote intelligent control is realized. The low-pass filter circuit allows a low frequency signal to pass and does not allow middle and high frequency signals to pass, the low-pass filter circuit has the effects that the middle and high pitch components in the audio signal are filtered, a low pitch component is enhanced to drive a low pitch unit of the loudspeaker, and the low pitch experience sense of the speaker can be increased. The protection circuit has the advantages of large output power, a small gain difference of two sound channels, no impact sound of the loudspeaker in turn-on and turn-off, and reliable overheat and overload short circuit protection. The remote intelligent control system has the advantages of a simple structure, a high degree of intelligence, a wide application range, and high creativity.

Description

technical field [0001] The invention relates to the technical field of loudspeaker control systems, in particular to a remote intelligent control system for musical instrument loudspeakers. Background technique [0002] The loudspeaker is a transducer device that converts electrical signals into acoustic signals, and the performance of the loudspeaker has a great influence on the sound quality. The loudspeaker is the weakest part in the audio equipment, but it is the most important part for the sound effect. There are many types of speakers, and their prices vary widely. Audio electric energy makes its paper cone or diaphragm vibrate and resonate (resonate) with the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. Low-grade plastic speakers have no sound quality because of their thin cabinets and cannot overcome resonance (there are also some well-designed plastic speakers that are far better than inferior wooden speakers); ...
