Insert for dampening acoustic vibration and shielding magnetic flux for use in a disc drive

摘要

The present invention is directed to an insert for use in a disc drive to dampen acoustic vibration and shield electronic elements from stray magnetic flux generated by a magnet assembly of a voice coil motor. The insert includes an acoustic insulator portion and a magnetic shield. The acoustic insulator portion is compressed between a base and a circuit board of the disc drive to suppress vibration of the circuit board. The magnetic shield is attached to the acoustic insulator portion below the magnet assembly and is shaped to shield a portion of the circuit board from stray magnetic flux generated by the magnet assembly.
