Abstract
The utility model relates to a multi-channel active loudspeaker box, comprising a left-channel loudspeaker box, a right-channel loudspeaker box, a central-channel loudspeaker box, a subwoofer-channel loudspeaker box and an encircling-channel loudspeaker box. The utility model is characterized in that at least two of the pluralities of loudspeaker boxes are connected in horizontal arrangement. The adjacent surfaces of the adjacent loudspeaker boxes share a side board, thereby forming the multi-channel active loudspeaker box which is of integral structure. Multi-channel reproduction is realized in a box body. The utility model has the advantages that the number of loudspeaker box and external lines are reduced and the systematic cost is lowered, and the multi-channel active loudspeaker box also has the advantages of novel structure, unique style and convenient placement.
Description
The utility model relates to a kind of multichannel active audio amplifier, specifically a kind of multichannel active audio amplifier that is applied to home theater and multimedia occasion.
Existing multichannel active audio amplifier generally is made up of L channel audio amplifier, R channel audio amplifier, center channel audio amplifier, subwoofer sound channel audio amplifier and surround channel audio amplifier.In the prior art, the audio amplifier of described each sound channel is an independently audio amplifier of difference, each audio amplifier is play single sound channel, for realizing multichannel reproduction, need with more independent audio amplifier and external connection, generally need two independent audio amplifiers of left and right acoustic channels at least, when 5.1 channel stereo playbacks, then need six independent audio amplifiers, especially in audition occasion closely such as multimedia, then need among a small circle, place six independent audio amplifiers if adopt 5.1 sound channel playbacks, more audio amplifier quantity and external connection not only make system cost increase, and put difficulty, use inconvenience.
The purpose of this utility model then is the problem that exists at above-mentioned prior art, a kind of multichannel active audio amplifier is provided, at least two a plurality of described audio amplifiers are incorporated in make single multichannel active audio amplifier in the overall structure, in a casing, realize multichannel reproduction, thereby reduce audio amplifier quantity and external connection, special structure makes described audio amplifier be horizontal strip, be fit to hang on the wall, flat crouching at desk and place, corner, not only reduced audio amplifier quantity, solve external connection and put problem, and reduced cost.
The purpose of this utility model can reach by following measure:
A kind of multichannel active audio amplifier system, comprise L channel audio amplifier, R channel audio amplifier, center channel audio amplifier, subwoofer sound channel audio amplifier, surround channel audio amplifier, it is characterized in that horizontally and be bonded together at least two a plurality of described audio amplifier, the shared side plate of the adjacent surface of adjacent audio amplifier forms an integrally-built multichannel active audio amplifier.
Described audio amplifier also can be a passive loudspeaker box.
The utility model has following advantage compared to existing technology:
1, replace a plurality of independent audio amplifiers in the existing multichannel sound box system with single multichannel active audio amplifier, reduce audio amplifier quantity and external connection.
2, easy-to-connect during use is put easily, be fit to hang on the wall, or flat crouching at desk and place, corner, reduce line and putting position.
3, unique horizontal strip structure, outward appearance shows unique characteristics, and is fashionable.
4, work simplification, convenient for production, cost reduces.
Below in conjunction with drawings and Examples the utility model is further described:
