Excuse me if this question is obvious.(adsbygoogle = window.adsbygoogle || []).push({});

Do mechanical waves propagate through loudspeaker diaphragms (whether they be elastic or rigid) in the same way that acoustic waves propagate through waveguides albeit a different medium? As far as I understand, reflections occur at the boundaries of the diaphragm due to a similar mechanism (an impedance mismatch) in the same way reflections occur at the mouth of a waveguide.

Assuming this is true, where would the source of the mechanical wave occur in a driver where the motor force is distributed uniformly over its surface (ESL/Ribbon) and for a driver whose motor force is not distributed uniformly (Dynamic Cone)?

Could diaphragm geometry be conceived in such a way to optimize its mechanical diffraction / reflection pattern to minimize and distribute the energy over a wider bandwidth?

Thanks,

Thadman
