Speaker Case

This product is speakers made by attaching piezoelectric film to phone case. Piezoelectric film, made by applying pressure to PVDF( PolyVinyliDene Fluoride), is light and resistant to shock. Piezoelectric film, even if it is film, has a good sound quality never inferior to other speakers. This product is more practical speakers since it is small in volume and handy to carry as opposed to existing smart phone speakers.
