1. 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, andthe 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.
