Patent ID: 7358621

Claim:
An electrical power generating and gaining device using sound waves and photic energy to generate magnetism comprising: a solar cell device; and a crystal microphone device including: a metallic film surface of the crystal microphone device providing metallic coil leading wires, one end of which are connected to a crystal of a resonance room in a natural frequency box and the other end of which is connected to a leading wire of a bottom electrode of the solar cell device so that an output leading wire below the crystal is connected to a leading wire of a top electrode of the solar cell device, wherein the leading wire of the solar cell device provides coils, and when mechanical vibration of the metallic film of the crystal microphone device is formed by an external sound wave frequency, the metallic coils of the vibrated metallic film transmit current to form a vibratile magnetic field to intersect the output leading wire coils of the solar cell device to respond and output a load current, meanwhile the leading wire coils generate a magnetic field when the solar cell device outputs the current to mutually respond with the vibratile magnetic field of the metallic coil leading wires of the metallic film.
