Abstract

The invention relates to a single sound box and a sound box system. The single sound box comprises a box body, an audio processing chip, a power amplifier module, a mid / bass unit, two or more plane wave equal-path treble waveguide horns and two or more treble units. When the single sound box works, the audio processing chip respectively sends two paths of signals to the power amplifier module, thepower amplifier module pushes the mid / bass units to produce sound according to mid / bass signals, and the power amplifier module also synchronously pushes the two or more treble units to produce soundaccording to mid / treble signals. Sound emitted by the treble units correspondingly enters the plane wave equal-path treble waveguide horns. The plane wave equal-path treble waveguide horns can be used for correcting the sound path of the treble units and emitting high-frequency audio of a plane wave line sound source, wherein the theory of the plane wave line sound source is that the distance isdoubled, the sound pressure is attenuated by 3db, and the plane wave line sound source is superior to the conventional point sound source (the distance is doubled, and the sound pressure is attenuatedby 6db), so that the high-frequency audio of the plane wave line sound source can transmit high frequency farther, the sound pressure is large, and the tone quality is good.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a single audio system and an audio system. Background technique [0002] Battery audio is a widely used audio equipment. Because of its portability, it does not need 220V strong electricity, and it can work outdoors by self-powered by its own battery. However, traditional battery speakers, due to low working power, insufficient sound pressure, poor sound quality and single acoustic theory, are usually only used in square dances, store advertisements, and small personal performances, etc. It is not suitable for occasions that require high sound quality and a large audio transmission area. Contents of the invention [0003] Based on this, it is necessary to overcome the defects of the prior art, and provide a single sound system and sound system, which can achieve strong sound pressure, long audio transmission distance and good sound quality, while also achieving small size, ligh...
