Vibration transducer for generating electricity, has pendulum moving in circular motion around rotation center based on vibration with reference to base, and magnet and coil are arranged to convert circular motion into electrical signal

摘要

The transducer has a pendulum suspended at a base. The pendulum moves in a circular motion (15) around a center of rotation, in response to a vibration with reference to the base. A magnet (16) and a coil (17) are arranged to convert the circular motion into an electrical signal. An electrical output is provided for coupling a load. The pendulum is fastened to an axle (10) which is rotatably supported over a support at the base.
