Talking about the related concepts of outdoor sound column

The outdoor sound column is a kind of speaker.

The general column is to sequentially load 4~10 paper cone speakers in the vertical direction. This arrangement results in a strong directivity in the vertical direction, and the directivity of the high frequency is more prominent. The sound column is especially suitable for buildings with large echoes, such as churches and large workshops.

The sound column is equipped with a number of cone-shaped speakers in the cabinet, ranging from 2 to 6 speakers. This kind of structure has strong directivity, especially the high-frequency directivity is the most prominent, and the sound quality is also greatly improved. Especially suitable for buildings with large echoes, such as churches/temples. With high-quality raw materials, the product has a real amplification effect on vocals and music. The sound is clear and the noise is small. The material is aluminum alloy, which is more suitable for outdoor use.

The sound column is composed of a plurality of speakers arranged and combined in the same phase. The pointing characteristics of the sound column are similar to a single speaker in the horizontal direction, but are greatly improved in the vertical direction. It spreads out like a fan in the horizontal direction, but has strong directional characteristics in the vertical direction, forming a thin and thick "plate"-like stereoscopic radiation effect. Install the sound column near the stage table and point the “sound disk” to the audience. The sound beam radiates to the back of the audience hall with strong sound energy. The front row is mutually different due to the phase difference caused by the different vertical distances of the speakers. The weakening may be lower than the sound pressure of a single speaker here, which tends to make the direct sound distribution of the sound field uniform. The horizontal direction of the sound column should not be “bundled” and there should be a large horizontal radiation angle so that the sound field can be relatively uniform in the left and right direction.
