Description

Manufacturing method of horn vibrating piece using positioning structure

The invention relates to a method for manufacturing a horn vibrating piece, in particular to a method for manufacturing a horn vibrating piece using a positioning structure.

According to the general, there are many kinds of non-metal parts substrates inside the speaker made of cloth. The main reason is that the specially treated cloth has appropriate elasticity and strength, and can provide the functions required by the speaker when it is operating. For example, vibrating pieces such as drum paper, elastic waves, connecting pieces, etc. belong to this category.

However, the manufacturing method of the horn vibrating plate mainly uses cotton cloth as the basic material, and then the cotton cloth is dipped in a liquid synthetic resin to absorb the synthetic resin in the cotton fibers, and the cotton cloth absorbing the synthetic resin is dried and hardened. The transverse fiber threads are fixed and bonded to each other at a certain position, and at the same time, the synthetic resin covers the surface of the cotton cloth to form a synthetic resin film that isolates both sides of the cotton cloth, and the cotton cloth with the synthetic resin film. Then, in the forming vibration piece, the cotton cloth is first unfolded and flattened, and then a plurality of forming blocks are formed on the cotton cloth, and the forming blocks are spaced at the same distance. Then, the cotton cloth is heated and pressurized by a mold, so that a plurality of vibration plate shapes are sequentially shrunk in the forming blocks. Finally, a cutting step is performed, and each shape of the vibrating piece is sequentially cut from the cotton cloth by a cutting device to obtain a plurality of vibrating pieces.

In addition, the manufacturing method of the conventionally known horn vibrating piece is mainly carried out continuously and automatically. Because the cotton cloth has elasticity, when the shape of each vibrating piece is shrunk from a flat shape, The position of each subsequent shaping block is affected by the shrinking force of the previous wave shaping block to shrink into an elastic wave shape, and is pulled forward for a distance. In this way, firstly, the forming mold cannot be accurately aligned with each subsequent forming block, resulting in incomplete formation of these elastic waves; secondly, the cutting equipment can also not accurately match Each forming block is formed after forming, so that the whole of the cut vibrating piece is incomplete.
