Description

Mould structure capable of elastically pressing and fixing a fixed wire elastic wave

This creation is related to a mold structure, especially a mold structure that can elastically press and fix a fixed wire.

Press, the general speaker includes the woofer, the midrange unit, and the tweeter. These three units are responsible for different frequencies; most of the 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 the electromagnetic field is at right angles to the magnetic field of the permanent magnet on the horn, this causes the movable coil to be subjected to motion in the gap; the mechanical force generated by this motion causes the paper disk attached to the voice coil to vibrate vertically, up and down, thereby The air is vibrated, the audio is transmitted to the human ear, and the sound is restored for the purpose of listening, thereby realizing the conversion of electric energy to sound energy.

However, since the damper in the horn is connected to the voice coil, and the main function of the elaboration is to hang the voice coil and the drum paper, the structure is mostly a plurality of concentric circles and the cross section is wavy. The elastic wave can support the voice coil and the drum paper, so the sound wave can directly affect the amplitude of the drum paper and affect the sound quality of the speaker.

In addition, the current wire elastic wave includes 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 elastic wave is mainly made of cotton cloth as the basic material, and the cotton cloth is dipped in the 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 elastic wave having an annular corrugation on the surface.

However, during warming and press forming, the hot pressing of the mold forms a surface and the outer ring surface of the hot pressing forming surface, which also heats the wires; the processing procedure causes damage to the wires, and Most of the wires are twisted or woven by a plurality of metal wires; the outer ring surface of the hot-pressed surface is not provided with other protective structures or reserved spaces, so that the adjacent ends of the wires are damaged. Seriously, the mold has no structure at both ends of the clamping wire to prevent misalignment caused by the forming shrinkage of the cloth and the wire during hot press forming.

Therefore, when the wire is bouncing for a long period of time, the damage caused by the forming and the misalignment of the wire may cause the wire to be completely deformed, and even the wire may be broken.

More specifically, when a wire bomb with a damage condition is installed in the horn, not only will the sound quality be affected, but also the wire bomb will be used for a long time, which will make the damage more serious and lead to the horn. The problem of shortened service life.

Therefore, the creators of this case have observed the above-mentioned deficiencies, but have not produced this creation.
