Title: Magnetic circuit converting oscillation sound into sound wave
Inventor: SHIMIZU MASAAKI
IPC: H04R9/02
Filed: 1993-09-13
Abstract: PURPOSE:To convert oscillation sound into sound wave through utilizing the distortion movement of a voice coil by making difference between strength of magnetic fields in the magnetic field of a speaker. CONSTITUTION:A hole 12 in the shape of a cylinder or a polygon over a triangle is made on a part of the circumference of a magnet 2 so as to mount a ferromagnetic material 5 into the hole 12. A magnetic circuit is formed by mounting a center pole 4 to the magnet 2, mounting a yoke plate 3 on the face of the magnet 2 on the side opposite to the pole 4 and inserting the voice coil 1 between the yoke plate 3 and the center pole 4. The ferromagnetic material 5 is mounted to a part of the hole 12 so as to make the change of magnetic force. In accordance with the change of magnetic force, the difference is generated between a flux on the side of the ferromagnetic material 5 and that at the other parts changes into the deforming movement at the part of the voice coil 1. The deforming strain movement of voice coil 1 moves strongly on the side of the ferromagnetic material 5 and weakly at the other parts so as to convert into the sound wave by the difference of the movements.
