Description

Horn vibrating plate partially provided with anti-noise layer and manufacturing method thereof

The present invention relates to a horn vibrating plate, and particularly relates to a horn vibrating plate partially provided with an anti-noise layer and a manufacturing method thereof.

Generally speaking, speakers include woofer, midrange, and tweeter. These three units are responsible for different frequencies. A typical moving coil horn, when the current flows through the wire to the voice coil, an electromagnetic field is generated. Because this electromagnetic field is at right angles to the magnetic field of the permanent magnet on the horn, the active coil is forced 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 realizes the electric energy to sound energy. Conversion.

In order to prevent the voice coil in the horn from contacting other metal components due to vertical and vertical vibrations, the non-metallic parts contained in the horn are made of cloth materials. The main reason is that the specially treated cloth materials have Appropriate elasticity and strength can provide the required functions of the horn when it is activated. Among them, the horn vibrating plate (or called the elastic wave Damper) is one of the most important components in the horn or speaker structure. The horn vibrating plate not only provides the horn or The better output power and audio characteristics of the speaker are also the basis for quality control when the speaker or speaker manufacturer manufactures the speaker or speaker.

The manufacturing method of the prior art horn vibrating plate includes an impregnation step, a baking step, a hot pressing step, and a rapid cutting step. Among them, the impregnation step is to impregnate the cloth in the resin, so that the cloth absorbs the resin, and forms a resin layer outside the fibers of the cloth, so that the cloth has a certain hardness. In the baking step, the resin-absorbing cloth is dried to remove moisture from the cloth.

However, the problem of the conventional speaker vibrating plate is that the resin on its surface is quite hard and rubs against the metal wire on it when it vibrates, causing it to generate noise when outputting audio, thereby affecting the sound quality of the speaker.

On the other hand, if the problem of friction between the horn vibrating plate and the metal wire during vibration is not solved, the vibrating plate may vibrate for a long time, causing the metal wire system to fail to be firmly connected to the voice coil and the input terminal. The connection will affect the output of the speaker's sound quality. In addition, the wire is more likely to be deformed, loose or broken due to the problem of misalignment.

In view of the above-mentioned shortcomings of the conventional packaging and carrying bag structure, the creator researched and improved ways to address these shortcomings, and finally came up with the present invention.

S7), and then perform the wire setting step (step S6).

It should be further explained that the anti-noise layer 420 has a thickness L, and the size of the thickness L is related to the anti-noise ability. When the thickness L of the anti-noise layer 420 is larger, the anti-noise ability is better; when the thickness of the anti-noise layer 420 is The smaller the L, the worse the noise immunity.

Specifically, referring to FIG. 5B, according to the second embodiment of the present invention, the horn vibrating plate 400 partially provided with the anti-noise layer 420 is produced by the following steps: adding a gluing step (step S7) before the impregnation step (step S2) , And then perform the wire setting step (step S6). In this way, the steps of hot pressing and cutting can be performed after completing the wire setting step (step S6). These steps have been described as the previous content, and the description will not be repeated here.

It should be further explained that the difference between the second embodiment of the present invention and the first embodiment is that the first embodiment performs the gluing step (step S7) after the cutting step (step S5), and vice versa. In the second implementation of the present invention, the sizing step (step S7) is performed before the impregnation step (step S2). As a result, since the gap between the fiber 110 and the metal wire 300 has not been occupied by the dried resin 200, the glue 220 can penetrate into the gap between the fiber 110 and the metal wire 300, so that the anti-noise layer 420 has With a larger thickness L, the horn vibrating plate 400 partially provided with the anti-noise layer 420 according to the second embodiment of the present invention has a better anti-noise ability.

Specifically, referring to FIG. 6B, according to the third embodiment of the present invention, the horn vibrating plate 400 partially provided with the anti-noise layer 420 is made by the following steps: after the cutting step (step S5), the wire setting step (step S6) is added. ), and then perform the gluing step (step S7).

It should be further explained that the difference between the horn vibrating piece 400 partially provided with the anti-noise layer 420 according to the third embodiment of the present invention and the above-mentioned embodiment is that it is performed after the wire setting step (step S6) is performed first. Gluing step (step S7). As a result, although the glue 220 cannot penetrate the gap between the fiber 110 and the metal wire 300 due to the wire setting step (step S6) first, the anti-noise layer 420 has a small thickness L and has poor noise resistance. , But on the other hand, since the wire setting step (step S6) is performed first and then the gluing step (step S7) is performed, the overflow layer 430 completely covers the metal wire 300, thereby preventing the metal wire 300 from being caused by vibration. The problem of dislocation occurs when deformed, loose or broken.

Therefore, the present invention has the following implementation effects and technical effects:

First, the present invention eliminates the noise generated by the vibration between the fiber 110 and the metal wire 300 when the horn is vibrated by the arrangement of the anti-noise layer 420.
