Distributed Mechanical Parameters of Loudspeakers, Part 2: Diagnostics
The mechanical vibration of a loudspeaker drive unit can be represented by a set of distributed parameters as a set of linear transfer functions. This representation can be used to distinguish mechanical and acoustical problems. Starting with an analysis of mechanical modes such metrics as accumulated acceleration level (AAL) can be used to interpret the vibration patterns. The smoothness in AAL is useful for predicting peaks in the sound pressure level (SPL) curve.
