Patent ID: 8546964

Claim:
A reciprocal vibration type power generator, comprising: a housing ( 100 ) having a hollow cylindrical shape; a tubular annular coil set seat ( 101 ) extending inwardly from one end of the housing ( 100 ); an annular power generation coil set ( 104 ) installed in a distal end of the tubular annular coil set seat ( 101 ), wherein: an annular space ( 103 ) is formed between the tubular annular coil set seat ( 101 ) and an inner wall of the housing ( 100 ), a cylindrical space ( 102 ) extends into the tubular annular coil set seat ( 101 ) from the distal end, and the annular power generation coil set ( 104 ) includes output wires ( 105 ) for outputting power generated in the annular power generation coil set ( 104 ); a motion block assembly ( 106 ) including a motion block ( 110 ), said motion block ( 110 ) having a cup-shaped structure from which extends an annular outer magnetic member ( 108 or 117 ), and said motion block ( 110 ) further including a center column ( 109 ) from which extends a columnar magnet ( 107 ), an inner annular space ( 111 ) being formed between the cup-shaped structure of the motion block ( 110 ) and a periphery of the center column ( 109 ), and between the annular outer magnetic member ( 108 or 117 ) and a periphery of the columnar magnet ( 107 ), wherein: said tubular annular coil set seat ( 101 ) and annular power generation coil set ( 104 ) extend into said inner annular space ( 111 ), said center column ( 109 ) and columnar magnet ( 107 ) extend into said cylindrical space ( 102 ), and said annular outer magnetic member ( 108 or 117 ) extends into said annular space ( 103 ), to enable reciprocal relative axial movement between the motion block ( 110 ) and the tubular annular coil set seat ( 101 ) when said generator is vibrated, said relative movement between the motion block ( 110 ) and the tubular annular 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 power.
