Description

Method for manufacturing wire bounce wave capable of controlling wire position

The present invention relates to a method for manufacturing wire bounce waves, in particular to a method for manufacturing wire bounce waves that can control the position of the wire.

Press, general speakers include woofer, midrange, and tweeter. These three units are responsible for different frequencies; most speakers work on the same principle. As a typical moving coil speaker, when current flows through the wire to the voice coil, an electromagnetic field is generated. 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 move in the gap; the mechanical force generated by this movement causes the paper plate attached to the voice coil to vibrate vertically and up and down, thereby The air is made to vibrate, and the audio is transmitted to the human ear to achieve the purpose of restoring the sound for human listening, and realizing the conversion of electric energy into sound energy.

However, since the horn vibrating plate (also called damper) in the horn is connected to the voice coil, and the main function of the damper is to suspend the voice coil and drum paper, the structure is mostly multiple concentric It is round and has a wavy cross-section. The voice coil and drum paper can be supported by the elastic wave. Therefore, the quality of the elastic wave can directly affect the amplitude of the drum paper and affect the sound quality of the horn.

In addition, the current wire bomb includes a body and a plurality of wires, which are fixedly combined with 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 traditionally used shaped wire elastic wave mainly uses cotton cloth as the basic material. The cotton cloth is impregnated with liquid synthetic resin so that the fibers of the cotton cloth absorb synthetic resin. After the cotton cloth absorbing synthetic resin is dried and hardened, it is further formed into plurals. The mold is heated, pressurized, and cut to form a wire elastic wave with ring-shaped corrugations on the surface.

However, during heating and pressure forming, the hot pressing surface of the mold and the outer ring surface of the hot pressing surface will also heat the wires; this processing procedure will cause damage to the wires, and the The wires are mostly twisted or braided by a plurality of metal wires; because the outer ring surface formed by the hot pressing is not provided with other protective structures or reserved space, it will cause damage to the adjacent ends of the wire. Serious; Moreover, the mold does not have a structure for clamping the two ends of the wire to prevent the misalignment caused by the shrinkage of the cloth and the wire during hot pressing.

Therefore, after a long-term vibration of the wire elastic wave, the damage and the misalignment of the wire during forming will cause the wire to deform as a whole, and even the wire may break.

In more detail, when a damaged wire bounce is installed in the speaker, it will not only affect the output of the sound quality, but the wire bounce will also cause more serious damage due to long-term use, which will lead to the speaker. The problem of shortened service life.

Therefore, after the inventor of the present case observed the above-mentioned deficiencies, he came up with the present invention.
