Abstract

PURPOSE:To establish the excellent electroacoustic converter of broad band, and small size, by restricting the production of harmful irregular oscillation, through the dispersed drive by the drive section of audio vibration with flat straight line type or radiation type. CONSTITUTION:The magnet pieces 1a-1d of triangle shape of electroacoustic converter are assembled in square shape with given magnetic gaps 5a-5d to constitute the magnetic circuit 6 having the magnetic gap in X-shaped manner. The magnet piece is constituted that the magnetic pole pieces 3, 4 of triangle shape are clipped on the both side of the permanent magnet 3 magnetized thicknesswise of triangle shape, and the magnetic plates up and down the magnetic pieces 1a to 1d have different polarity of magnet pole adjacent and form 8 magnetic gaps. The voice coil 7 in X shape is vertically and oscillation freely inserted to the magnetic gap 5, and the entire coil 7 is moved upward with the current i flowing to the coil. The coil conductor 9 is formed on the coil 7 with the insulation plate 8.
