Study on mechanical design aiming at improvement of sound quality : influence of structure around loudspeaker on sound quality

Recently, market demand for smaller, powerful and a high sound quality electronics is rapidly posing a major challenge to design products. Mechanical design considering the acoustic characteristics is essential for the development of information technology equipments.Especially, audio and visual equipment requires smaller package and higher sound quality, so it is important to design the mechanical package taking the sound and vibration characteristics into account. Therefore, clarifying relationships between mechanical design, acoustic characteristics and sound quality are strongly desired. For example, perforated structure for protecting loudspeaker unit is indispensable to attach, relationships between design parameters or sound characteristics of such structure and sound quality are still unclear.In this report, effects of mechanical design around loudspeaker on noise and vibration characteristics were examined experimentally and classified the effects into design guideline.修士(工学)法政大学 (Hosei University
