o Minimized the limitation on the designing of appearance and made it possible to print on the film surface by using film materials

o Expanding the range of applications with the features of wafer-thin, light, and water resistance (interior, clothes, high-tech devices, swimming pools, etc.)

o No limitation on the size, the price competitiveness stems from the decrease in production cost comparing to the production of the conventional speakers.

o Available function of microphone and sensor, various applications (Mobile Phones, Telecommunication Equipments, Security Equipments, etc.)

  Fundamentals of operating the Film Speaker

o Piezoelectric high polymers can be transformed by electricity. Thickness becomes expanded when the length and width are contracted, while it becomes contracted when the length and width are expanded.

Film contraction and expansion continues if AC electrical signal is given
