Description

Forming and cutting horn vibrating piece manufacturing device and manufacturing method thereof

The present invention relates to a horn vibrating plate manufacturing device and method, in particular to a forming and cutting horn vibrating plate manufacturing device and manufacturing method.

Press, general speakers include woofer, midrange, and tweeter. These three units are responsible for different frequencies. Most speakers work on the same principle. Like 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, so that the air vibrates and the audio is transmitted to the human ear to achieve the purpose of sound restoration for human listening, and realize the electric energy to sound energy. Conversion.

However, since the vibration plate (damper, also known as elastic wave) in the horn is connected to the voice coil, and the main function of the vibration plate is to suspend the voice coil and drum paper, its structure is mostly multiple concentric circles and the cross section is Wavy, the vibrating plate can support the voice coil and drum paper, so the quality of the vibrating plate can directly affect the amplitude of the drum paper and affect the sound quality of the speaker.

In addition, the current wire vibrating piece 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 formed wire vibrating plate is mainly based on cotton cloth. The cotton cloth is soaked in liquid synthetic resin, so that the fiber of the cotton cloth absorbs the synthetic resin, and the cotton cloth that absorbs the synthetic resin is dried. After hardening, it is further heated, pressurized and cut by a plurality of forming dies to form a wire vibrating piece with ring-shaped ripples on the surface.

However, in the above-mentioned vibrating plate manufacturing process, the cutting process is to press the mold to form, and then move the formed material to the cutting device.

Position, thereby reducing the quality of the vibrating plate after cutting; second, to use an automatic conveying device to move the press-formed material to the pre-cutting position in the cutting device, and furthermore, due to the need to use an automatic conveying device To move the material, there will be a problem of long process time; to be more specific, whether it is manual or automated movement, the process time will be long and the product yield will be low. Therefore, the above problem has become a speaker vibrator Important issues in the manufacturing process.

In addition, after the process of heating and pressure forming, the mold will also heat the wires. This processing procedure will cause damage to the wires. Most of the wires are twisted or braided by multiple metal wires. , When the wire vibrating plate vibrates for a long time, the damage caused by the forming will cause the wire to deform as a whole, and even the wire may break. Therefore, when the damaged wire vibrating plate is installed in the horn operation, it will not only affect the output of the sound quality, but also the long-term use of the wire vibrating plate will make the damage more serious, which will shorten the service life of the speaker. .
