Embodiment 1

[0063] As Example 1, a shielded storage device 10 was manufactured by forming a vibration-proof storage case 21 for housing a hard disk drive as the storage main body 11 in the following dimensions and shapes. Figure 7 The result of measuring the noise when the shielded storage device 10 is assembled and mounted in different types of personal computers is shown.

[0064] As the vibration-proof storage box 21, a steel plate with a thickness of 1.6 mm was processed to manufacture the vibration-proof cover 22 and the vibration-proof plate 27, and the vibration-proof storage box 21 was formed into a box shape with a length of 220 mm, a width of 140 mm, and a height of 50 mm. On the upper surface portion 22a of the anti-vibration cover 22, a stepped convex portion 23b that is a step of 1.5mm is formed by drawing processing, and on the side surface portion 22b, a stepped convex portion 24b that is a step of 1.5mm is formed by drawing processing . Also on the anti-vibration plate 27,...

Embodiment approach 2

[0068] Figure 8 It shows the structure of the anti-vibration storage case of the electronic device which is the second embodiment of the present invention figure 1 The sectional view corresponding to the A-A line in . Figure 9 yes means Figure 8 The structure of the vibration-proof storage box for the electronic device shown in figure 1 The cross-sectional view corresponding to the B-B line in . The second embodiment has basically the same configuration as the above-mentioned first embodiment, so the same symbols are assigned to these same structures, and the characteristic parts will be described (the same applies to other embodiments described below).

[0069] Such as Figure 8 and Figure 9 As shown, in the storage device 40, instead of one of the vibration-damping members 31 attached to the stepped convex portion 23b of the vibration-proof cover 22 of the vibration-proof storage box 21 that accommodates the storage main body 11, a heat-conducting member 41 is pas...

Abstract

A vibration-damping containing case for an electronic device is provided with stepped projections for holding the electronic device, which is a vibration source, so as to sandwich the outer surface of the electronic device, and the stepped projections are located on the inner surface of a case member for containing the electronic device so as to cover the outer surface of the electronic device. The stepped projections hold the outer surface of the electronic device through vibration-damping members.

Description

technical field [0001] The present invention relates to a vibration-proof storage box for an electronic device, the electronic device, and electronic equipment equipped with the electronic device. A vibration-proof storage box, the electronic device, and electronic equipment carrying the electronic device. Background technique [0002] Generally, an electronic device having a drive unit that operates mechanically is accompanied by vibration. In particular, in an electronic device in which the driving unit operates at high speed, it becomes a vibration source, and the vibration may be transmitted to the outside, and the vibration may become noise. [0003] For example, in recent years, with the development of digital information and communication technology, broadband services for delivering large-capacity content have penetrated and spread, and users can enjoy animation, music, etc. Along with this, the amount of information processed by electronic devices such as personal...
