Abstract:
Distributed mechanical parameters describe the vibration and geometry of the sound radiating surface of loudspeaker drive units. This data is the basis for predicting the sound pressure output and a decomposition of the total vibration into modal and sound pressure related components. This analysis separates acoustical from mechanical problems, shows the relationship to the geometry and material properties, and gives indications for practical improvement. The tutorial combines the theoretical background with practical loudspeaker diagnostics illustrated on various kinds of tranducers such as woofer, tweeter, compression driver, microspeaker, and headphones.
