ABSTRACT:
A peripherally extending acoustic compliance area in a disc drive housing which reduces emission of acoustic noise by the disc drive. The housing includes first and second plates and side walls which cooperate to form an enclosure for an excitation source disposed within the housing. At least a selected one of the plates has a contact point to which the excitation source is mechanically coupled, a first portion of the selected plate surrounding the contact point and a second portion thereof disposed between the first portion and an outer perimeter of the selected plate, with the second portion having an increased compliance with respect to the first portion. The increased compliance can be formed by reducing the thickness of the second portion. Damping material can be additionally supported by the second portion to provide further acoustic noise reduction.
