Title:
VIBRATION DAMPER AND DAMPING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2010/150385
Kind Code:
A1
Abstract:
Provided are a vibration damper capable of damping vibrations at various frequencies of a mount member, and a damping mechanism provided with the vibration damper.
A damping mechanism (1) is provided with an inner panel (7), a speaker (4), and a vibration damper (5). The inner panel (7) is vibrated by the speaker (4). A vibration damper mounting portion (9) for mounting the vibration damper (5) thereto is provided in the surface of the inner panel (7). The vibration damper (5) is provided with a magnetic circuit portion (12) and a vibration portion (13) provided with a conductive member (27) disposed in a magnetic gap (G) of the magnetic circuit portion (12). The vibration portion (13) is provided to be able to be vibrated with respect to the magnetic circuit portion (12) by an elastic member (30), and a mass body (31) is mounted to the vibration portion. Either one of the magnetic circuit portion (12) or the mass body (31) of the vibration portion (13) is mounted to the inner panel (7).
