Advantages and disadvantages of various speaker cone materials

Tweeters are generally classified into three broad categories according to the material of the diaphragm: hard dome, soft dome and composite dome.

The hard dome is made of light metals such as aluminum alloy and titanium alloy, and it is formed by ultra-thin platinum alloy, and the surface is chemically treated. Its sound is bright and transparent, and it has high resolution.

The soft dome is made of silk soft membrane, the sound is delicate and soft, and the expressive force is strong. The composite diaphragm dome is composited with diaphragms of several materials. For example, some diaphragms use a composite diaphragm of "silk juan + aluminum". This tweeter not only has the bright sound quality and resolution of the hard dome, but also the natural and smooth, layered sense of hearing of the silky soft dome.

　　 The current common tweeter materials mainly include titanium film, silk film, PV film, etc. In multimedia speakers, PV film and silk film dome tweeters are mostly used, and it is generally believed that the latter's tweeter is better than the former.

　　The common materials used to make woofers are paper cones, ceramic cones, bulletproof cloth, wool cones, polypropylene, etc.

　　Paper cone: It has the advantages of rigidity and flexibility, high internal damping, and easy mixing with other materials. The tone performance is natural and thick, and the bass is full. The disadvantage is that the moisture resistance is poor, and the consistency is difficult to control during manufacturing. Because of the low cost of the paper cone, it is widely used in multimedia speakers below 300 yuan.

　　 Ceramic cone: The performance of vocals and classical music is very delicate, the mid-bass is very transient, full and powerful, good dynamic performance, excellent bass, and accurate positioning. It is suitable for expressing the appeal and shock of surging movie sound sources.

Bulletproof cloth cone: has a wider frequency response and lower distortion, can withstand greater power, can produce warm, natural intermediate frequency and deep, sharp low frequency, good transients, and play great dynamic music effects Excellent, is the first choice for those who love strong bass.

Wool fiber cone: The Shuba paper cone has wool fibers infiltrated into the pulp, and the texture is slightly softer. It also performs well for soft music and has a natural and natural voice. The disadvantage is that the bass effect is not good, and the expressiveness of rock music and marches is not satisfactory. If you are a person who likes to listen to melodious music and don't pay much attention to the bass effect, the wool basin is the best for you. Listening to symphonies with it will definitely make you feel like you are on the scene.

PP CONE: It is popular in high-end speakers, with good consistency and low distortion, excellent performance in all aspects, wide range of applications, but higher prices.
