On the other hand, the second magnet that is provided at the peripheral of the equalizer is magnetized to the direction of path and the side of inner peripheral is set as the north pole and that of the outer peripheral is set as the south pole. The flow of the magnetic flux from the center pole 3 to a diaphragm 8 and an equalizer 10 that causes the trouble of the magnetic leakage repulses the magnet flux of the second magnet and immediately after it comes out from the center pole 3, is curved to the outer peripheral direction and passes the magnetic path to return to the south pole of the magnet 1 through the plate 4 and a plate 5. Thus, the leakage of the magnetic flux from a speaker to forward is remarkably reduced.

Title: Format signal generating method for optical recording medium
Inventor: SANADA KAZUO
IPC: G11B20/12
Filed: 1989-03-13
Abstract: PURPOSE:To easily remake a signal generator corresponding to a format signal by accessing a memory by a sequencer each time arithmetic processing is finished and successively outputting a stored arithmetic result as the format signal. CONSTITUTION:A memory 7 is accessed by a computer 6 and the arithmetic processing result is stored. After the arithmetic processing is wholly finished or each time the processing is finished, the memory 7 is accessed by a sequencer 1 and the stored arithmetic result is successively outputted as a format signal (g). Accordingly, even when the format is changed to the other type of the format, it is enough to change a program, with which the computer 6 is operated, to a form corresponding to the format. Thus, it is not necessary to remake a hardware circuit each time the format is changed. Then, the manufacture cost and manufacture time of the signal generator can be reduced.
