<p><P>PROBLEM TO BE SOLVED: To provide a silent computer structure for effectively preventing the leakage of a noise from a computer. <P>SOLUTION: Sound absorbing materials 18 are attached to almost the whole internal region of a case body 4 incorporating a CPU part 6, a power source circuit 15 and drive parts 9 and 10, and the drive parts 9 and 10 are individually covered by sound absorbing materials 17 independent of the sound absorbing materials 18 of the case body part 4. The individual drives 9 and 10 as a noise generation source are individually covered with the independent sound absorbing materials so that it is possible to facilitate countermeasures to a noise according to the characteristics of the noise of each drive. Furthermore, when silence is inadequate, the case body 4 is configured of an inner wall 4a and an external wall 4b in a double structure, and silencing materials 19 are packed between the internal part 4a and the exterior wall 4b. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
