| Abstract(in English) | In this paper, we study a method for analyzing compact acoustic reproduction systems through acoustic equivalent circuit. In recent years, the improvement of sound quality has been demanded as the mobile phones are made smaller and more complicated. However, the design of acoustical structure for mobile phones increases more and more difficulty. Generally, the analysis through acoustic equivalent circuits is used for the design of acoustic systems. However, the conventional acoustic formulae cannot be used for the real acoustic design. We therefore modify the acoustic formulae so that the relative position of acoustic holes can be explained through the acoustic equivalent circuit. |
