OPTIMIZATION OF AN ACOUSTIC MEMBRANE ARRAY

An acoustic device (100) comprises an array of acoustic membranes (1,2,3,4) formed on a foil (10). Each of the acoustic membranes (1,2,3,4) is configured to vibrate at a resonance frequency (Fr) of the acoustic membranes (1,2,3,4) for generating respective acoustic waves (W1,W2,W3,W4). Relative phas...
