More specifically, the present invention relates to a personal computer. More specifically, the present invention relates to a personal computer that facilitates expandability of a storage device or an optional device, prevents structural floppy disk drive errors, and enables stereo mounting of internal speakers. A component system of a computer.

All personal computers up to now have a main printed circuit board 2 in a given space as shown in FIG. A switching mode power supply 1; A hard disk drive 6 which is an auxiliary storage device; A floppy disk drive 3 to which a read / write head is attached; A chassis 4 constituting the body; A speaker 5; A fan 7 which serves to discharge air inside the personal computer to the outside; A device such as an air hole 8 into which air enters is mounted.

The floppy disk drive 3 and the hard disk drive 6, which are storage devices, have almost standardized sizes, and the main printed circuit board 2 and the switched mode power supply 1 differ in size from computer manufacturer.

The size of the personal computer is therefore determined by the number and arrangement of storage devices and the size of the main printed circuit board 2 and the switching mode power supply 7.

However, the computer determined by the above-described conventional method is difficult to change to or add another kind of memory because of the fixed size and sub space. That is, there is no expandability.

In addition, in the case of the personal computer having the structure as shown in FIG. 1, air emitted by the fan 7 behind the switched mode power supply 1 is sucked through not only the air hole 8 but also the floppy disk drive 3. .

However, the conventional air flow of the above-described path is a dust of the air sucked into the floppy disk drive (especially 5.25 inches), and the read / write head of the floppy disk drive 3. Because of this problem, read / write errors occur.

In addition, in the case of a multimedia personal computer, when two internal speakers are mounted for the stereo of the multimedia, the speakers should be separated from each other from the front as far as possible to maximize the stereo effect. Because of the narrow space, it is difficult to mount the speaker.

Therefore, an object of the present invention is to solve the disadvantages of the prior art, and to facilitate the expandability of the storage device or the optional device in a personal computer, and to prevent read / write errors of the structural floppy disk drive 3. And to provide a component system of a personal computer to facilitate the stereo mounting of the internal speaker.

The configuration of the present invention to achieve the above object comprises a first module comprising a main printed circuit board, a switching mode power supply, a cooling fan, an air hole, a bus board and an internal speaker; A connection cable connected to the first module; It is connected to the connection cable and exchanges information with the first module, and consists of a second module consisting of a hard disk drive and a floppy disk drive.

Another configuration of the present invention to achieve the above object, the first module consisting of an option slot that is easy to expand and replace; A second module that is easy to expand and replace and is configured of a main printed circuit board which performs main control of a computer system; A third module that is easy to expand and replace, and comprises a hard disk drive and a floppy disk drive for storing data, and which does not generate air flow; A fourth module comprising a switching mode power supply for supplying power, a cooling fan for removing heat generated from the switching mode power supply, and an air hole for passing out heat; The modules are composed of connecting cables which are connected to each other to facilitate expansion and replacement.

When described with reference to the accompanying drawings the most preferred embodiment which can easily implement this invention by the above configuration as follows.

As shown in FIG. 2, the configuration of a component system of a personal computer according to an embodiment of the present invention includes a main printed circuit board 11, a switching mode power supply 12, a cooling fan 20, and an air hole 9 A first module (17) comprising a bus board (10) and an internal speaker (13); A connection cable 18 connected to the first module; A second module connected to the connection cable to exchange information with the first module 17, and comprising a hard disk drive 14, a 3.5-inch floppy disk drive 15, and a 5.25-inch floppy disk drive 16 19).

As shown in FIG. 3, another configuration of the component system of the personal computer according to the embodiment of the present invention includes: a first module 21 configured of option slots; A second module 22 composed of a main printed circuit board; A third module 23 comprising an auxiliary memory device such as a hard disk drive and a floppy disk drive; A fourth module 24 comprising an air hole 26, a cooling fan 27, and a switching mode power supply 28; It consists of a connection cable 25 for connecting the modules so as to exchange information with each other.

The operation of the component system of the personal computer according to the embodiment of the present invention by the above configuration will be described with reference to FIG.

When the personal computer user applies power to the computer, the operation of the component system of the personal computer according to the embodiment of the present invention starts.

When the operation starts, the computer's main printed circuit board 11, the switching mode power supply 12, the bus board 10, the internal speakers 13, the connecting cables 18, the hard disk drive 14 and the 3.5 inch The floppy disk drive 15 and the 5.25 inch floppy disk drive 16 are operable, and a cooling fan 20 that acts as a cooling fan rotates and only air is sucked into the air holes 9.

Therefore, since the air flow does not occur in the second module 19 on which the floppy disk drive 15 is mounted, the occurrence of lead / write errors can be reduced.

If there is a device to be replaced in the first module or the second module, only that device can be replaced.

In addition, since the space of the first module is large, two internal speakers for stereo can be easily mounted.

The operation of the component system of the personal computer according to another embodiment of the present invention by the above configuration will be described with reference to FIG.

When the personal computer user applies power to the computer, the operation of the component system of the personal computer according to the embodiment of the present invention starts.

When the operation starts, the computer's main printed circuit board 22, the switching mode power supply 28, the option slot 21, the connecting cable 25, and the auxiliary storage device 23 are operable, The fan 20 rotates and the air is sucked only through the air hole 26.

Therefore, since the air flow does not occur in the auxiliary memory device 23, the read / write error is reduced.

In the first module, the second module, and the third modules, if there is a device to be replaced, only the device can be replaced.

In addition, since the space of the first module is large, two internal speakers for stereo can be easily mounted.

As described above, in the embodiment of the present invention, a conventional personal computer is componentized to facilitate the expandability of storage devices or options in the computer, and to prevent read / write errors of structural floppy disk drives. A component system of a personal computer having an effect of facilitating stereo mounting of an internal speaker can be provided.
