Wireless transceiving column loudspeaker

Abstract

The invention discloses a wireless transceiving column loudspeaker which comprises a box body, a power amplifier and a wireless transceiver and is characterized in that the power amplifier is arranged inside the box body; the power amplifier is connected with a plurality of groups of sound amplification loudspeakers; and the wireless transceiver is arranged inside the box body. The wireless transceiving column loudspeaker disclosed by the invention has the advantages of reliability for working, convenience in operation, high working efficiency, wireless transceiving function and the like, and has a very high practical value.

Description

technical field [0001] The invention relates to a sound column, in particular to a wireless receiving sound column. Background technique [0002] The so-called sound column generally has more than two speakers arranged in an array to produce a flat sound field. Within a certain listening range, the sound attenuation is much lower than that of a point sound source. For example, at a listening distance of 5m, the point sound source attenuates by about 14dB, while the attenuation of a well-designed sound column is only 7dB, which follows a double gap, so the farther the distance is, the more obvious the gap will be. Of course, this is also achieved within the effective range of the plane field of the sound column. For specific information, please refer to some books on acoustics. The advantage of this is that within a certain listening distance, the proportion of direct sound greatly exceeds that of reflected sound (or ambient sound), so that the impact of the room or environ...

Problems solved by technology

[0004]At present, most of the sound columns on the market are based on the principle of speakers and add simple circuits to form a good sound quality effect. The functions are single and cannot meet the market demand.
