Technical Field

The present invention relates to a speaker vibrating reed, and more particularly, to a speaker vibrating reed with noise-resistant wires and a method for manufacturing the same.

Background

The general loudspeaker comprises a bass unit, a middle-pitch unit and a treble unit, wherein the three units are respectively responsible for different frequencies. A typical moving coil loudspeaker generates an electromagnetic field when current flows through the wires to the voice coil, which is forced into the gap by the moving coil to move as a result of the field being oriented at right angles to the field of the permanent magnet on the loudspeaker. The mechanical force generated by the movement makes the paper disc attached with the voice coil generate vertical and up-and-down vibration, so that the air vibrates to generate audio signals to be transmitted to human ears, the purpose of restoring the audio signals for human listening is achieved, and the conversion of electric energy to sound energy is realized.

In order to avoid the contact of the voice coil in the speaker with other metal components due to vertical and up-and-down vibration, various non-metal component substrates contained in the speaker are made of cloth materials, mainly because the specially processed cloth materials have proper elasticity and strength, and can provide the requirements of the required functions when the speaker is actuated, wherein, a speaker vibration plate (or called elastic wave Damper) is also taken as one of the most important components in the structure of the speaker or the speaker, and the speaker vibration plate not only provides the better output power and audio characteristics of the speaker or the speaker, but also is the basis of quality management when the speaker or the speaker manufacturer manufactures the speaker or the speaker.

The manufacturing method of speaker vibrating plate in the prior art includes the steps of dipping, baking, hot pressing and cutting. The impregnation step is to impregnate the fabric into the resin, so that the fabric absorbs the resin, and a resin layer is formed outside the fibers of the fabric, so that the fabric has certain hardness. And the baking step is to dry the cloth absorbing the resin so as to remove the moisture in the cloth.

However, the conventional speaker vibrating reed has a problem in that the resin on the surface thereof is hard and rubs against the wires thereon during vibration, causing noise during outputting audio signals, thereby affecting the sound quality of the speaker.

On the other hand, if the problem that the vibrating plate of the loudspeaker and the wire rub each other when vibrating is not solved, the wire cannot be stably connected with the voice coil and the input terminal due to the long-time vibration of the vibrating plate, so that the output of the tone quality of the loudspeaker is influenced, and in addition, the wire is more likely to be deformed and loosened or broken due to the dislocation.

In view of the above-mentioned disadvantages of the conventional loudspeaker diaphragm, the inventor has developed an improvement to the disadvantages and finally has made the present invention.
