Pulse signal generator having integrally made detecting assembly and waveform shaping circuit

A pulse signal generator comprising:

• a detection assembly for detecting a movement of an object to be detected;
• and
• a waveform shaping circuit having two threshold values, said detecting assembly including:
• a magnetic element wire capable of producing a large Barkhausen jump in response to said movement of said object,
• a wire bobbin surrounding said magnetic wire,
• a coil wound around said wire bobbin and generating a series of electric pulses, and
• a pair of output terminals connected to both ends of said coil, wherein said magnetic element wire, said coil, and said output terminals are integrated with said wire bobbin as a unit, and said waveform shaping circuit shaping a waveform of said electric pulses to output a pulse signal and being integrated with said detecting assembly.
