Patent ID: 8736086

Claim:
A reciprocal vibration type power generator, comprising: a housing ( 100 ); a coil set seat ( 101 ); an annular power generation coil set ( 104 ) supported by the coil set seat ( 101 ) and including output wires ( 105 ) that extend through the coil set seat ( 101 ) to a space between the coil set seat and the housing ( 100 ); a motion block ( 110 ) including an annular outer magnetic member ( 108 or 117 ) and a columnar magnet ( 107 ), an inner space ( 111 ) being formed between the annular outer magnetic member ( 108 or 117 ) and a periphery of the columnar magnet ( 107 ), wherein said coil set seat ( 101 ) and annular power generation coil set ( 104 ) extend into said inner space ( 111 ) to enable reciprocal relative axial movement between the motion block ( 110 ) and the coil set seat ( 101 ) when said generator is vibrated, said relative movement between the motion block ( 110 ) and the coil set seat ( 101 ) causing said columnar magnet ( 107 ) and said annular outer magnetic member ( 108 or 117 ) to move reciprocally past the annular power generation coil set ( 104 ) and thereby generate electric power; a rectifying and charging circuit ( 300 ) included in said housing ( 100 ) and connected to the output wires ( 105 ) for rectifying the electric power generated in said annular power generation coil set ( 104 ); an anode input/output terminal ( 410 ) installed on the housing ( 100 ) and connected to an anode terminal of the rectifying and charging circuit ( 300 ); a cathode input/output terminal ( 420 ) installed on the housing ( 100 ) and connected to a cathode terminal of the rectifying and charging circuit ( 300 ), said anode and cathode input/output terminals ( 410 , 420 ) being for inputting electric power from an external source and for outputting electric power from the rectifying and charging circuit ( 300 ) to outside the housing ( 100 ); a power storage device ( 310 ) included in said housing ( 100 ) for storing rectified electric power received from the rectifying and charging circuit ( 300 ) and to output the electric power from the rectifying and charging circuit ( 300 ) or input the electric power from the external source through the anode and cathode input/output terminals ( 410 , 420 ) installed on the housing ( 100 ).
