Abstract
The acoustic device can be used in a broad series of loudspeakers as a source of sound, as well as in microphones subject to sound which is converted in other signals. The acoustic device includes a panel (20B), fitted laterally to its thickness and capable of maintaining flexural vibrations provoking subsequent acoustic effect of the panel in the desired operating acoustic frequency range. The panel has bending strength distribution which changes along its surface for the conversion of the acoustic effect, the centre (27, 28) of the bending strength of the panel being shifted from its geometric centre (25). 52 claims, 12 figures
