The classification of speakers
The classification of speakers have different angles and the standard, according to the acoustics speakers, have closed box, phase and frequency reflection box (box), passive transmitter speakers, transmission of sound, in their respective characteristics related to ask. Pour in the market at present is the mainstream, From the speaker's size and place, have landed box and bookshelf box, the former size is larger, the general magnified directly under the speakers, sometimes in the installation of the shock absorber with JiaoDing. Due to the large volume box landed box, and easy to use more and more, the low-frequency usually woofer is better, and output level is high, power, and loading capacity for listening area or require overall situations. Bookcase box smaller, usually on foot, the characteristic is placed on flexible, not to occupy a space, but the volume and soil woofer diameter and the number of limits, the low-frequency usually less power and ground, bearing output level is also a little smaller, suitable for use in listening, According to replay the frequency band width, most sound box is to design goal as wide band covering broad-spectral-bandwidth speakers, belong to. The most common narrow band speakers with family cinema and interest is low sound box (subwoofer), only for reduction of ultralow frequency to a very narrow frequency band, According to whether the built-in amplifier, can be divided into passive and active speakers, the former speakers have built-in amplifier, can be divided into passive and active speakers, the former speakers have built-in amplifier and the latter has now, most household speakers are passive, but low notes for active speakers are usually.
