<P>PROBLEM TO BE SOLVED: To provide a speaker structure which resonates while being attached to an object. <P>SOLUTION: In a speaker structure 1, a first magnet 22 is disposed in a magnetic circuit part 2, and a second magnet 63 is disposed on a lid plate 62 of a transmission part 6 so as to repulse the magnetic force generated by the first magnet 22. A bobbin 31 is biased in a direction of moving away from the magnetic circuit part 2 by utilizing the repulsive magnetic forces generated from the first magnet 22 and the second magnet 63, and a voice coil 32 is disposed in a repulsion magnetic circuit part Y formed by the repulsive magnetic forces generated from the first magnet 22 and the second magnet 63. <P>COPYRIGHT: (C)2012,JPO&INPIT |
