Speaker material : Usually the multimedia speakers are designed with a two-unit two-way design. A smaller speaker is responsible for the output of the mid-high sound, and another larger speaker is responsible for the output of the mid-bass.
The tweeter of multimedia active speakers is now dominated by soft domes. Its combination with digital audio sources can reduce the harshness of high-frequency signals, giving people a feeling of gentleness, smoothness, and exquisiteness.
There are four common materials for bass units: 1. Paper cones, which have the advantages of natural sound, cheapness, good rigidity, high internal damping and so on. The disadvantages are poor moisture resistance and difficulty in controlling consistency during manufacture. 2, bullet-proof cloth woven basin, there is a wide frequency response and low distortion, is the first choice for people who love strong bass. Disadvantages are high cost, complicated production process, and unsatisfactory light music effects. 3, wool woven basin, slightly soft texture, the advantage is the performance of soft music is perfect. The disadvantage is that the bass is not good, and the expressiveness of rock music and marching music is not satisfactory. 4, Pp (polypropylene) basin, widely popular in high-end speakers, good consistency, low distortion, performance in all aspects are very good, but expensive.
Cabinet material : The common computer speakers in the market today are mainly plastic and wooden. Two of the different materials have their own advantages. The advantage of plastics is that it is easy to process and the appearance can be done better. In a large batch of production, it can be done at a very low cost. But it does not mean that plastic is synonymous with low-end, like some well-known foreign brands, also use plastic materials in high-end products, but also a good sound. However, the domestic manufacturers are quite satisfactory in terms of plastic material density and processing technology, and they generally use plastic boxes for medium and low-end products. Nowadays, most of the low-priced wooden speakers use the medium-density board as the material of the box, while the high price is the real pure wood used in most cases as the box material, and the resonance and sealing of the box must be avoided. Sex, to ensure the thickness of the box board, the degree of bonding between the boards is a key factor affecting sound quality.
Speaker type : The speaker can be divided into 2.0, 2.1, 4.1, 5.1, 7.1 types according to the number of cabinets. The ".1" channel is a specially designed subwoofer. This channel can produce subwoofers with a frequency range of 20 to 120Hz.
