| Abstract(in English) | In this paper, we design mobile phones by using the design support software we constructed for compact acoustic systems. It is difficult to design mobile phones whose frequency response using the ITU-T P.57 Type3.2 High-leak coupler is within the GSM mask. In other words, it is very difficult to satisfy the request with existent diaphragms, sounder, structure, sizes, and so on. Hence, we study ideal structure and sizes satisfying the request by using the design support software in this paper. Moreover, we analyze the obtained design results and then study a guideline for the design of mobile phones satisfying the above request. |
