The speaker fitting injection cone is characterized by simple structure and high energy conversion efficiency. Speaker accessories The injection cone is mainly divided into four types: treble, midrange, bass and full-band. The basic structure of each type is the same, except that the caliber and the diaphragm are different. However, the cone-shaped high-pitched sound unit has been replaced by a high-pitched sound unit such as a dome and a horn because of its small radiation surface and low rate.
The diaphragm material of the speaker fitting injection cone is mostly made of pulp material, which is what we usually call "paper cone". The pulp is also blended with wool, silk, carbon fiber and other materials to increase its rigidity, internal damping and waterproof properties. The sound of the paper cone is smooth and natural, and it has a good performance for the details of the transient response and the sense of hearing, but the disadvantage is that the moisture resistance is poor, so other materials are added to improve its performance. However, many high-end speakers still favor the paper cone.
In addition to the paper cone, the cone speaker unit also uses non-paper diaphragm materials, such as polypropylene, ceramic, mica carbonized polypropylene, carbon fiber textile, bulletproof cloth, hard aluminum foil, CD corrugated, fiberglass and other composite materials. Improved performance. For example, ceramic pots are very delicate for vocals and classical music. The mid-bass is very transient, full and powerful, with good dynamic performance, excellent bass and accurate positioning.
In addition, by the way, the horn type speaker unit works in the same way as the cone, except that the sound is radiated differently. The cone speaker unit radiates sound directly from the diaphragm, while the horn speaker unit vibrates after the diaphragm vibrates. The sound is diffused out through the horn and belongs to the indirect radiant type.
