Description

Horn vibrating piece with anti-noise layer wire and its manufacturing method

The present invention relates to a horn vibrating piece, in particular to a horn vibrating piece with an anti-noise layer wire and a manufacturing method thereof.

A general speaker includes a woofer, a midrange unit, and a tweeter, and these three units are responsible for different frequencies. In a typical moving coil speaker, when the current flows through the wire to the voice coil, an electromagnetic field will be generated. Since this electromagnetic field is at right angles to the magnetic field of the permanent magnet on the speaker, the moving 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, so as to achieve the purpose of restoring the sound for human listening, and realize the conversion of electrical energy to sound energy. transform.

In order to prevent the voice coil in the speaker from contacting other metal components due to vertical and up and down vibrations, many of the non-metallic parts contained in the speaker are made of cloth. The main reason is that the specially treated cloth has Appropriate elasticity and strength can provide the required function of the horn when it is actuated. Among them, the horn vibrating sheet (or Damper) is one of the most important components in the horn or speaker structure. Better output power and audio characteristics of loudspeakers are also the basis for the quality control of loudspeaker or loudspeaker manufacturers when manufacturing loudspeakers or loudspeakers.

The manufacturing method of the horn vibrating piece in the prior art includes an impregnation step, a baking step, a hot pressing step and a cutting step. The impregnation step is to impregnate the cloth into the resin, so that the cloth absorbs the resin, and forms a resin layer on the outside of the fibers of the cloth, so that the cloth has a certain hardness. The baking step dries the resin-absorbing fabric to remove moisture from the fabric.

However, the problem of the prior art speaker vibrating piece is that the resin on its surface is quite hard, and when vibrating, it rubs with the wires on it, causing noise when outputting audio, thereby affecting the sound quality of the speaker.

On the other hand, if the problem of friction between the speaker vibrating piece and the wire during vibration is not solved, it may be vibrated for a long time by the vibrating piece, so that the wire system cannot be firmly connected to the voice coil and the input terminal. It affects the output of the speaker's sound quality. In addition, the wires are more likely to be deformed, loose or broken due to the problem of dislocation.

In view of the above-mentioned shortcomings of the conventional loudspeaker vibrating plate, the creators have researched and improved the method for these shortcomings, and finally the present invention is produced.
