Classification of professional audio speakers

　　1. Paper vibration film. The paper basin diaphragm appeared earlier, and it was also a common speaker unit vibration membrane material. At present, the technical level is quite mature. The sound characteristics of the container vibration membrane are smooth and natural, and there are few stimulating parts with a clear personality, which is in line with the tastes of most people. The paper basin has the advantages of light quality and high energy conversion efficiency; the disadvantage is that the paper basin is more sensitive to temperature and humidity, and it is obviously affected by the environment. After several extreme environmental changes, it may produce unrestricted deformation. With the advancement of technology, the paper bowl unit used by Jazz Dragon Spelling manufacturers has good waterproof properties and excellent performance.

　　2. Plastic film, also known as PP sound basin, is generally made of polypropylene material. It is also a common diaphragm material. It has excellent damping characteristics and is soft and natural. The advantage is that it is more moisture -proof and waterproof than the paper basin. The disadvantage is that the rigidity is relatively general, and it is easy to cause distortion at high frequencies.

　　3. Metal diaphragm. Metal diaphragm is generally made of aluminum or its alloy material. The advantage is that the sound is clear, the dynamic and analysis of power are outstanding, and it can control the distortion well. The disadvantage is that the damping characteristics of the metal diaphragm are relatively weak, and the performance of high -frequency is prone to "metal sounds" (that is, the phenomenon of pot splitting generated by high -frequency end), but it can be improved by applying special coatings on the surface of the diaphragm.

　　4. Synthetic fiber film. The material of the synthetic fiber diaphragm is transplanted from the material of the aviation army. The advantage is that the quality is light, high -strength, and has the characteristics of various materials of various materials, but the manufacturing cost is high, which is generally found in high -level audio.
