Energy self-sufficient electrical fitting, such as switch, has moving coil connected to rectifier circuit via transformer

摘要

The electrical fitting has an electromechanical transducer which converts pressure changes in a gas into electrical energy, which is rectified and stored (14). The transducer includes an electromagnetic induction coil in the form of a moving coil (8) of an electroacoustic transducer (5) connected to a diaphragm via a moving coil suspension (9). The moving coil moves within a permanent magnet (6), and is connected to the primary winding (11) of a transformer (10), the secondary winding of which the rectifier circuit (13) is connected.
