Abstract

In this paper, we describe the acoustic design used for mobile phones. Today's mobile phones provide a variety of audio capabilities, such as telephone communication, television, music, and movies. These capabilities are achieved by using acoustic devices such as receivers, speakers, and headphones. The most important of these devices are the speakers, which are used for almost all the audio functions of the mobile phone. However, today's mobile phones are much slimmer and more stylish than their predecessors, while maintaining a very high performance. The speakers used for these phones must be thin and small, but provide high-quality sound. Until now, the speakers used in mobile phones have had the problem of being too thick and difficult to mount. In this study, we analyzed the correlation between the acoustic structure of mobile phones and their acoustic properties and formulated design guidelines for achieving high-quality sound in slim mobile phones, which we also describe here.
