Combination acoustics can be divided into mini combination acoustics and home cinema set commonly. Mini combination acoustics, it is miniaturized combination acoustics actually, opposite to home cinema set, the characteristic of mini combination acoustics is miniaturized, common mini combination acoustics by all sorts of play equipment and the host machine that result put is integrated add two sound boxes to constitute. The composition of mini sound is also divided into different forms, some mini sound and even speakers are connected together with the host can not be split, the main purpose of this is to carry and move easily, occupy small space, so this mini combination of sound is also called bed sound; Some also come with multiple speakers, which is intended to accentuate the ambient effect of the sound. Such speakers may also use wireless technology to connect the host to each speaker for ease of placement.
