Description

technical field [0001] The invention relates to a manufacturing device and method of a horn vibrating piece, in particular to a forming and cutting horn vibrating piece manufacturing device and a manufacturing method thereof. Background technique [0002] Press, a general speaker includes a woofer, a midrange unit, and a tweeter. These three units are responsible for different frequencies. Most speakers work on the same principle. As in 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 oriented at right angles to the magnetic field of the permanent magnet on the horn, this forces the moving coil to move within 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, achieving the purpose of restoring the...

Problems solved by technology

[0005] However, in the above-mentioned vibrating plate manufacturing process, the cutting process is all formed by pressing the mold, and then the formed material is further moved to the cutting device. However, there are two ways to move the material to the cutting device: 1. In order to use manual movement, there is still the problem of human eye error in the manual movement method, and after the production personnel often work for a long time or have different proficiency, the position in the cutting device often deviates from the cutting position , so as to reduce the quality of the vibrating piece after cutting; secondly, to use the automatic conveying device to move the press-formed material to the pre-cutting position in the cutting device; For this material, there will be a problem of long process time; more specifically, no matter whether it is manual or automatic movement, the process time will be long and the product yield rate will be low. Important issues in the manufacturing process

[0006] In addition, through the process of heating and press forming, 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 braided by multiple metal wires. Therefore, when the vibrating piece of the wire vibrates for a long time, the damage caused by the forming will cause the overall deformation of the wire, and even the wire breakage will occur.

Therefore, when the wire vibrating piece with damage is installed on the speaker, it will not only affect the output of the sound quality, but also the damage of the wire vibrating piece will be more serious due to long-term use, which will shorten the service life of the speaker.
