Abstract
PURPOSE:To coincide the center of coil winding width with the center of magnetic flux density distribution, by obtaining a maximum voltage of a voltmeter while moving a gap gauge and a voice coil up and down and coupling the damper with a vibration diaphragm at the position. CONSTITUTION:With a lead 20 of a voice coil 9 connected to a DC voltmeter 21, an adjusting screw 19 is turned left and right to move a gap gauge 14 up and down and the coil 9 is moved up and down, then a voltage E=Blv (where; B is magnetic flux of a magnetic gap 11, l is effective length of voice coil, and v is mobile speed of voice coil 9) appears at the voltmeter 21. When the maximum point of the voltage E is obtained, the center of the magnetic flux density distribution is almost coincident with the center of winding width of a coil section 9' of the coil 9. With this state, the damper and the vibration diaphragm are coupled to complete the speaker.
