Comparison of modal parameters of loudspeakers in different working conditions

摘要

The basic subject of this paper are vibrations of a loudspeaker's membrane. Dynamic behaviours of loudspeakers with an opened and closed basket and with a quasi-conical paper diaphragm are presented. An electromechanical driving system of a loudspeaker was not considered. A woofer was either mounted in a closed cabinet or it was freely suspended; a tweeter (with a closed basket) was investigated as freely suspended.
