The characteristics of the speaker unit:
Let US XDEC speaker today tell about the some factors which influence speaker
The speaker unit is composed of paper cones, magnets, coils and other materials, and its various material parts have an important influence on the characteristic curve and quality of the XDEC speaker unit. Therefore, it is often heard that the appearance of the speaker cone material and the speaker frame Body size determines the quality of its sound. In fact, this is very wrong. For example, if there are two woofers with the same cone but different sizes, it is not possible to obtain a better sound with a larger size. More low frequency characteristics, because the smaller size of the monomer may use a larger magnet inside, which has a higher magnetic number density, so it can have better low frequency characteristics than a larger size monomer. Below we will use the monomer The structure is analyzed:
Structure classification:
Front diaphragm type: It is used by general speakers. Place the diaphragm directly in front and you can see the material of the diaphragm. Its sound is to oscillate the sound directly through the diaphragm and release it into the air.
Rear diaphragm compression horn monomer: The diaphragm is placed directly behind, and the material of the diaphragm cannot be seen. The way of sound is to squeeze the sound oscillated by the diaphragm through a compression tube, so that the sound can be evenly diffused into the air In the medium, the listener can obtain better positioning and clearer high-resolution sound quality. In addition, it can divide the crossover point to the middle frequency part, so the speaker with the compressed tweeter horn can get better mid-range and thicker vocal sound.
Speaker internal material:
Diaphragm: By pushing the speed of the diaphragm, high and low frequencies are generated, including aluminum ribbon, ceramic, silk, titanium, and beryllium. The material of beryllium is extremely light.
Magnets: including natural magnets, neodymium, and iron. Alnico has the highest magnetic density, neodymium is the second, and iron is the lowest. The higher the magnetic density, the better the control, the more real sound can be obtained.
Coil: A metal wire is wound in a circumferential manner, which generates polarity through the conduction of current, and then attracts and repels the magnet to push the diaphragm surface and emit sound. The winding direction will affect the monomer The phase; the thickness, shape and material of the metal wire used will affect the overall efficiency and heat resistance of the monomer (whether it can withstand high power); the length of the coil winding will affect the impedance of the speaker, generally aluminum flat wire, The round wire is preferably an aluminum flat wire, which can make the coil and the magnet more closely, with the smallest gap, so the efficiency is highest, but the disadvantage is that it is not easy to manufacture when the coil is wound.
