In this paper we describe the design of novel, ultra-thin piezoelectric speakers for mobile phones. Due to the expansion of the slim mobile phone market, ultra-thin speakers providing high-quality sound are in strong demand. Piezoelectric speakers are much thinner than the electrodynamic speakers generally used in mobile phones. However, to achieve high-quality sound, the rigid structure and low internal friction of piezoelectric speakers must be improved. In this study, we have successfully developed highly reliable 0.9-mm-thick piezoelectric speakers that consist of a piezoelectric bimorph transducer and an elastic support structure and that provide high-quality sound. We have also successfully used these ultra thin speakers in a slim mobile phone. Copyright
