| description | This paper describes an approach to design of acoustic devices, such as microspeaker and dynamic receiver, considering the acoustic characteristics improvement in IMT-2000 mobile phones. The analysis of a newly designed microspeaker considering mechanical, electrical, and magnetic coupling effects is performed using the finite-element method (FEM) and its validity is confirmed as well by experiments. Also, a statistical approach is suggested to identify a certain relationship between a mobile phone and a newly designed microspeaker. The approach is based on the Taguchi method and utilizes the orthogonal array for design of experiments (DOE). The concept of signal-to-noise (S/N) ratio is applied to evaluate the acoustic performance in mobile phones. |
