An anti-acoustics streamline apparatus is provided. The apparatus includes an air impedance wall having a front face, a rear face, and a plurality of openings extending from the front face to the rear face defining open areas; and a plurality of flow separating structures disposed adjacent to the front face, each of the plurality of flow separating structure extending vertically along the front face of the wall. The openings are configured to define first wall regions in the air impedance wall adjacent to each of the plurality of flow separating structures and second wall regions between the first wall regions. A first ratio of the open areas in the first wall regions to a total area in first wall regions is larger than a second ratio of the open areas in the second wall regions to a total area in the second wall regions.

A hard disc driver housing (100) includes one or more counter-vibration devices (100) to absorb rotational vibration or gyration of a hard disc drive (HDD) (106). The device (110) incorporates at least one soft, plastic sphere and a pair of concave dished surfaces facing each other and maintaining the sphere between them. The sphere of the counter-vibration device (110) supports the hard disc drive (HDD) whilst the weight of the HDD may align the dishes with each other and over the sphere. In this manner, the sphere may act as a spring and allow the HDD to vibrate or gyrate without transmitting the mechanical movement to the rest of the HDD assembly or electronic device.

A mounting component for mounting an electronic part has a base that extends along a first surface of the electronic part, and a pair of left side and right side surface supporting sections that are extended from the base and bent along the right and left side surfaces of the electronic part, respectively. The pair of side surface supporting sections each have the screwing through hole at a position close to the one of the front end surface and the rear end surface. Further, a cushion member is interposed between the base and the electronic part, at a position close to the other of the front end surface and the rear end surface of the electronic part. The electronic part is screwed to the base through the surface supporting sections.

Requirement: An object of the present invention is to provide a disk apparatus that includes a vibration-damping mechanism capable of substantially curbing vibrations due to eccentricity of the center of gravity of a discoid recording medium, caused to a drive chassis on which mounted are a motor for rotationally driving the discoid recording medium, and a record-playback unit for recording a digital signal onto and/or playing that back from the discoid recording medium. Solution: A vibration-damping mechanism for the drive chassis (1) is configured in such a manner that insulators (11) each are placed in at least three respective predetermined positions of a drive chassis (1) on which a motor (2) and an optical pickup unit (5) are mounted, and a weight plate (10) is floatingly and movably supported on the drive chassis (1) by way of the insulators (11), wherein the shape of the weight plate (10) is determined based on a predetermined vibration-damping frequency, the at least three respective predetermined positions, and a spring constant of the insulators (11) which are identical to each other.
摘要:
In a device (101), comprising a support structure, a hard disk drive (121), having a printed circuit board at one side and a substantially plane plate at the opposite side, at least one mounting pad (131) having at least one layer of viscoelastic material, the hard disk drive (121) is mounted to the support structure via the mounting pad (131) and the substantially plane plate of the hard disk drive (121) faces the support structure. An air gap present between the support structure and the substantially plane plate of the hard disk drive enables flowing of air via this air gap for cooling of the substantially plane plate.
