Transducer apparatus having magnetic flux generators with pole pieces, reciprocators and closing pieces for channeling magnetic flux

An electromechanical transducer apparatus for converting between mechanical energy and electrical energy, the apparatus comprising:

• a first magnetic flux generator and a second magnetic flux generator, each including a plurality of pole pieces, a first pole piece of the plurality of pole pieces coupled to direct magnetic flux from a respective magnetic flux generator of the first and second magnetic flux generators and a second pole piece of the plurality of pole pieces coupled to direct the magnetic flux back to the respective magnetic flux generator, the first and second magnetic flux generators being adjacently disposed such that pole pieces of the first and second magnetic flux generators having opposite polarity are adjacently disposed in spaced apart relation;
• a pair of reciprocators mechanically coupled for reciprocating movement between the pole pieces of the first and second magnetic flux generators which are adjacently disposed, each reciprocator of the pair of reciprocators being spaced apart from the plurality of pole pieces of the first magnetic flux generator by a first air gap and spaced apart from the plurality of pole pieces of the second magnetic flux generator by a second air gap;
• a closing piece disposed to complete a magnetic circuit for channeling the magnetic flux generated by either of the first and second magnetic flux generators between the pair of reciprocators,
• wherein when the pair of reciprocators are disposed such that the first air gap is smaller than the second air gap, the magnetic flux generated by the first magnetic flux generator flows in a first direction via the first air gap through the closing piece;
• and
• wherein when the pair of reciprocators are disposed such that the second air gap is smaller than the first air gap, the magnetic flux generated by the second magnetic flux generator flows in a second direction via the second air gap through the closing piece, the second direction being opposite to the first direction;
• and
• at least one-current carrying coil disposed to electromagnetically interact with the magnetic flux passing through the magnetic circuit.
