Abstract
An electromechanical transducer comprising a radiating structure whose active element is formed by a polymer film placed between two electrodes. The invention provides a transducer in which a closure element having the exact shape of a spherical surface portion is connected to at least one active peripheral suspension which simulates the movements of a pulsating sphere portion completing the closure element.
