Description

Horn vibrating piece mold structure with forming protection structure

The author is related to a mold structure, in particular to a horn vibrating piece mold structure with a shaped protective structure.

Press, the general speaker includes the woofer, the midrange unit, and the tweeter. These three units are responsible for different frequencies. Most speakers work on the same principle. Like a typical moving coil horn, an electromagnetic field is generated when current flows through the wire to the voice coil. Since this electromagnetic field is at right angles to the magnetic field of the permanent magnet on the horn, this forces the movable coil to be subjected to motion within the gap. The mechanical force generated by this movement causes the paper tray attached to the voice coil to vibrate vertically, up and down, thereby vibrating the air, transmitting audio to the human ear, achieving the purpose of sound restoration for listening, and realizing electrical energy to sound energy. Conversion.

However, since the damper (also known as the elastic wave) in the horn is connected to the voice coil, and the main function of the vibrating piece is used to hang the voice coil and the drum paper, the structure is mostly a plurality of concentric circles and the cross section is The wavy shape can support the voice coil and the drum paper by the vibrating piece. Therefore, the vibrating piece can directly affect the amplitude of the drum paper and affect the sound quality of the horn.

In addition, the current wire vibrating piece comprises a body and a plurality of wires, and is fixedly coupled to the body through at least one wire, and one end of the wire is connected to the voice coil, and the other end is connected to the input terminal. The conventionally used shaped wire vibrating piece mainly uses cotton cloth as a basic material, and the cotton cloth is dipped in a liquid synthetic resin, so that the fiber of the cotton cloth absorbs the synthetic resin, and the cotton cloth absorbing the synthetic resin is further subjected to the plural forming after drying and hardening. The mold is heated, pressurized, and cut to form a wire vibrating piece having annular corrugations on the surface.

However, when heated and pressed, the mold will also cause hot pressing of the wires. This processing procedure will cause damage to the wires, and the wires are mostly twisted or woven by a plurality of metal wires. After a long period of vibration of the wire vibrating piece, the damage caused by the forming of the wire vibrating piece may cause the whole wire to be deformed, and even the wire breakage may occur.

In more detail, when the wire vibrating piece with damage is installed in the horn operation, not only will the sound quality be affected, but also the wire vibrating piece will be used for a long time, which will make the damage more serious and lead to the use of the horn.
