밀폐박스 상태의 가상 라우드스피커 매개변수 규명법 및 개선된 밀폐박스 모델링

Abstract

It was proposed to identify Thiele Small Parameters for loudspeaker attached to closed-box using known dynamic mass of moving parts. Also, enhanced PSPICE circuit model for closed-box loudspeaker system was proposed to more accurately simulate real closed-box loudspeaker system. Frequency dependent parameters were used to model voice coil inductor. Acoustic pressure response curves and electrical impedance curves were simulated and investigated by PSPICE circuit model according to compensation filter`s parameters. Finally, proposed method is expected to be utilized for identification of pseudo Thiele Small parameters of microspeaker.
