Because of its box body, low grade plastic sound box is flimsy, cannot overcome resonance, without sound quality at all (also the plastic sound box that has had a partial design wants far better than inferior woodiness sound box); Wooden sound box reduced the sound that box body resonant place causes catches, sound quality is generally better than plastic sound box. Multimedia speakers are usually two-unit dichonic design, with one smaller speaker for mid to treble output and another larger speaker for mid to bass output.
Choose sound box should consider the material of these two loudspeakers: the treble unit of multimedia active sound box is given priority to with soft ball head now (still have the titanium film ball head that uses at analog sound source in addition), it and digital sound source photograph cooperate to be able to reduce the stiff feeling of high frequency signal, give a person with gentle, smooth, exquisite feeling. Multimedia sound box shows the soft ball such as the PV film with better quality and lower cost is in the majority. Bass unit it decided the characteristic of the sound of sound box, the choice rises a few more important relatively, the commonest have the following kinds: paper basin, again have basin of base of woolen of apply glue paper, paper, tight suppress basin to wait a few kinds. Paper basin sound is natural, cheap, good rigidity, light material, high sensitivity, the disadvantage is poor moisture resistance, manufacturing consistency is difficult to control, but the top HIFI system with paper basin manufacturing is everywhere, because the sound output is very average, good reducibility. Bulletproof cloth, with a wider frequency response and low distortion, is the first choice of strong bass lovers, the disadvantage is high cost, complex production technology, sensitivity is not high light music effect is not very good. Wool woven basin, soft texture, it is very good for soft music and light music performance, but the bass effect is not good, lack of strength and shock.
The loudspeaker size is naturally the bigger the better, the larger the woofer can have a better performance in the low frequency part, this is in the choose and buy can be selected. Speakers made with high-performance speakers mean lower transient distortion and better sound quality. The loudspeaker of a common multimedia speaker is usually between 3 and 5 inches. Speakers made with high-performance speakers also mean lower transient distortion and better sound quality.
