Title: Speaker
Inventor: FUSE YUUZOU
IPC: H04R11/00
Filed: 1981-10-31
Abstract: PURPOSE:To make the winding material of a coil thick by providing two small magnets held at a specified interval having such polarity that they repel each other with a coil for generating a magnetic field in their common axial direction, and allowing a current flowed through the coil to drive the small magnets. CONSTITUTION:Two flat magnets 2a and 2b fixed to the bobbin 3 of a cone 1 with an adhesive 4, etc., are magnetized in the thickness direction. Further, a ring 6 made of a magnetic material for cutting off magnetic flux is provided at the circumference of a circular coil 5 for driving the magnets 2a and 2b in the Z-axis direction. By a magnetic field generated in the Z-axis direction when an audio current flows through the circular coil 5, electromagnetic force operates on those two magnets 2a and 2b to oscillate the cone 1. Thus, the coil 5 for driving the speaker is provided independently of an oscillation system, so the winding material of the coil is made thick to reduce the DC resistance of the coil.
