ABSTRACT:
This invention describes an electromechanical amplifying sound transducer including a diaphragm which responds to input energy, such as acoustical waves and mechanical pulses, and vibrates in response thereto. Conductive supports mounted onto the diaphragm are adapted to be interconnected to a source of electrical energy. A weighted conductive bar is loosely coupled to the supports and interconnects them. The supports transmit the vibrations to the bar whereby the bar can control the electrical energy delivered from the source of electrical energy so that the acoustic waves or mechanical pulses are converted into amplified electrical waves.
