Dear sir / madam A Film-Speaker is made by plasma technology. It has been very difficult to make super thin speaker. However our company modification technology is possible to make the special sound film. And by this special sound film, we make a live sound speaker more good than general speaker. For hearing a sound. It should be changed to electric signal and transmitted to a speaker through electric wire or electric wave. Then a diaphragm vibrates air and reproduces the original sound. In this course the conventional speakers occupied much space and had to keep fixed form like a cone shape or an oval in order to reproduce good sound with the help of resonance. There are many ceramic parts in conventional speaker and there are several steps containing high temperature process to form ceramic parts. But a film speaker has a very big advantage of simple process. In case of a conventional speaker. Sound is changed into electric signal and supplied to voice coil. It vibrate diaphragm hence vibrate air to reproduce sound. But the conventional speakers occupied much space and hand to keep fixed form like a shape or an oval in order to reproduce good sound with the help of resonance. Also there are many ceramic parts in conventional speaker and there are several steps containing high temperature process to form ceramic parts.Manufa cturing process of a film speaker is very simple and it has diverse functions, which a conventional speaker does not have. And we will do the best to provide our customers with the best quality products continually in the future. In order to diversity our existing market, we are interested in supplying our high quality products to you on favorable terms.
