Comprehensive stereophonic draw-bar sound equipment

Abstract

The invention provides comprehensive stereophonic draw-bar sound equipment, which comprises a draw-bar box body, a draw bar arranged at the rear part of the draw-bar box body, a pair of alto loudspeakers which are transversely arranged in the draw-bar box body and face the front part of the draw-bar box body, and a pair of tweeter units which are transversely arranged in the draw-bar box body, face the front part of the draw-bar box body and are respectively arranged above the corresponding alto loudspeakers, and a mega bass horn unit which is arranged at the bottom part of the draw-bar box body and faces the front part of the draw-bar box body. When the music is played, the music is sent out from the two alto loudspeakers, so that the stereo playing effect is very obvious, and the sense of immediacy is stronger. Besides, the two tweeter units are respectively arranged on the two sound box positioning positions, and high pitch components in the music can be respectively emitted from the tweeter units arranged at the left and right positions, so that the high pitch layering sense of the music is stronger, and stronger auditory pleasure can be generated. Meanwhile, the mega bass hornunit can generate a vigorous and steady bass effect.

Description

technical field [0001] The invention relates to the technical field of trolley audio, in particular to a comprehensive stereo trolley audio. Background technique [0002] Professional audio is suitable for environments such as indoor performances, so the sound quality and timbre of the music it plays will be very good, but relatively speaking, it will be large and inconvenient to move. The trolley speaker is widely used in outdoor occasions due to its convenient mobility, such as playing background music when the crowd dances. [0003] However, most of the existing trolley speakers are monophonic designs. In other words, the existing trolley speakers only have one speaker inside the trolley box, which means that there is only one fixed and single sound source position, and music can only be played from a single position. The speaker is emitted, so the sound field is thin, and the sound quality is much inferior to that of binaural or multi-channel. The latter has at least tw...
