Abstract
An electro-acoustical transducer device is disclosed, which includes: a hollow disk body that generally defines an axis of propagation, the hollow disk body comprising: a pair of plate members extending substantially perpendicular to the axis of propagation, each provided with a central transmitting port arranged about the axis of propagation, and a peripheral enclosure jointing the pair of plate members at the respective outer edge portions thereof, thereby defining a chamber of resonance between the pair of plate members; wherein a ring-opening about the axis of propagation that enables access to the chamber of resonance is formed between the central transmitting ports of the plate members.
