Description

Comprehensive stereo pull rod sound equipment

Technical Field

The invention relates to the technical field of pull rod sound equipment, in particular to a comprehensive stereo pull rod sound equipment.

Background

The professional sound box is suitable for environments such as indoor performance, so that the sound quality and the tone of music played by the professional sound box can be well played, but the professional sound box is relatively large in size and inconvenient to move. Due to the convenient mobility of the pull rod sound box, the pull rod sound box is widely applied to outdoor occasions, such as playing background music when people dance.

However, most of existing rod stereo systems are designed in a mono sound channel, in other words, only one speaker is arranged inside a rod box, which means that only one fixed single sound source position is provided, and music can only be emitted from the speaker in the single position, so that the sound field is thin, the sound quality is much inferior to that of a dual channel or multi-channel, and the latter has at least two sound boxes and corresponding two positioning positions, so that the music with rich layers can be played in layers through different sound boxes under the cooperation of corresponding power amplifiers, and therefore, the stereo effect is better and the presence is stronger.

In addition, because the existing pull rod sound adopts a single-channel design, the corresponding sound equipment only has one tweeter unit, and therefore, the similar technical problem exists, namely, the high-pitch component in the music can only be emitted from the tweeter unit at a single position, so that the sound field is single and thin, and the sound quality is inferior to that of a dual-channel sound or a multi-channel sound.

Accordingly, there is a need for an improved pop-up sound system that overcomes the above-mentioned deficiencies of the prior art.
