Title:
VIBRATION SPEAKER
Document Type and Number:
Japanese Patent JP3492983
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To maximize a vibration amount by providing a signal input means each for generating sound and generating vibration, so as to cause vibrating member to resonate in the vertical direction.
SOLUTION: The vibration speaker consists of a case 10, a sound-generating vibration plate 20 whose outer end is fixed and connected to an upper part of the case 10, a cylindrical voice coil 30 whose upper end is fixed and connected to a bottom face of the vibration plate 20, a vibration member 40 obtained by integrally combining a magnet 41 that is vertically polarized at the bottom of the voice coil 30 and a yoke 42 attached to the magnet 41 to form a magnetic circuit, a vibration coil 60 of a single-phase winding that is attached to the bottom of the case 10 at a lower part of the vibration member 40 and resonates the vibration member 40 vertically with interaction with the vibration member 40, and an elastic member 50, that connects the vibration member 40 to the case 10 for supporting the vibration member 40.
