DESCRIPTION JPH1169485
[0001]
[Industrial application field] audio.
[0002]
[0002] Voice coil only.
[0003]
[Problems to be solved by the present invention] Elimination of distortion of voice coil current.
[0004]
[Means for Solving the Problems] A fixed secondary coil is provided and a negative feedback is
generated by the voltage generated in this coil.
[0005]
The electromagnetic induction is induced from the voice coil current, and the electromotive force
appears in the fixed secondary coil.
[0006]
[Example] Power is applied from the voice coil terminal 7 to the voice coil 1 of the fixed
secondary coil speaker from the main amplifier, and the voltage induced in the fixed secondary

coil 2 is negatively fed back to the main amplifier from the secondary coil terminal , Ground to
the main amplifier from the ground terminal 9.
[0007]
[Effect of the invention] Distortion is reduced.
