| Abstract(in English) | Since the piezoelectric elements began making a beep sound, there were significantly difficulties, such as resonatingat high frequencies and reproducing at only narrowband. As a result, in speaker market many dynamic speakers have been useful by the advantages of wideband reproduction and high sound quality. Recently, various mobile applications were growing in popularity, so development of several speakers, such as small and lightweight, was speedy growth, as well as various electric comportments. Now, we are successfully producing the card speaker, Model WM-R57A, which satisfies several difficult demands; "Thin and Light"; "Reproduction from 150Hz to 100kHz"; "High Quality Sound". |
