Coupled vibro-acoustic simulations of piezo-actuated surfaces

Electro-mechano-acoustic analyses are performed to evaluate the vibrational response and the sound pressure generated by generic piezo-actuated surfaces.

Optimizing the number and position of the actuators relative to the vibrating surface is crucial for maximizing sound efficiency.

Numerical results predict the displacement field and sound pressure generated by a piezo-actuated surface to support innovative loudspeaker design.
