Abstract

PURPOSE:To reduce the output distortion to great amplitude input, by equally dividing the voice coil having the same winding width as the thickness of magnetic pole plate constituting the magnetic gap toward winding width, and constituting the bridge circuit in serial parallel connection of the coil and two FETs. CONSTITUTION:The magnetic gap is formed between the external circumference of the center pole 2 and the inner circumference of the magnetic pole plate 4, the coil bobbin 5 fitting the damper 6 is located in this gap, and the voice coils 7, 7' having the same thickness as the magnetic pole plate 4 are wound on the bobbin 5. These coils 7, 7' are divided equally into two toward the winding width, the source of FET8 is connected to one end of the coil 7 divided by two, another end of the coil 7 is connected to the drain of FET8', the drain of FET8 is connected to one end of the coil 7', and another end is connected to the source of FET8' to constitute the bridge circuit. Further, the balance of the magnetic flux density of the coils 7, 7' is held by the bridge circuit to prevent the production of the output distortion to greater amplitude input.
