Boasting to be the world’s first ultra-thin (0.9 mm) waterproof piezoelectric speaker, this latest model (VSLBG1914E1400-T0) from Koyoto-based Murata Manufacturing Company Ltd comes as a cost-effective solution to be used in such mobile devices as PDAs, digital cameras and 3G mobile phones for  better quality sound output. As opposed to the conventional dynamic speakers which require covering of the sound output holes with waterproof sheets to achieve waterproof quality,  these piezoelectric speakers are already waterproofed with no use of waterproof sheets hence eliminating the cost of sheet material, its application and the eventual degradation of sound quality caused by the covering.

They are available now with the sample price announced to be 250 yen per unit.
