[embodiment]

[first embodiment]

Fig. 2 A illustrates the synoptic diagram according to the CD-ROM drive of the utility model first preferred embodiment, and Fig. 2 B illustrates the sectional view according to the CD-ROM drive of the utility model first preferred embodiment.Fig. 2 C illustrates the front elevation according to the CD-ROM drive of the utility model first preferred embodiment.

Please be simultaneously with reference to Fig. 2 A and Fig. 2 B, the CD-ROM drive 200 of present embodiment for example is Disc player (compactdisc player, CD player), laser optics video disc player (laser optical video disc player, LDplayer), videodisc player (video compact disc player, VCD player), digital video Disc player (digital video disc player, DVD player) or other can have and dial the CD-ROM drive of putting the device function etc.

From the above, CD-ROM drive 200 comprises a housing 210, a panel 220, a discs pallet 230, a driver module 240, a discs data processing module 250 and a beam 260, and wherein discs pallet 230, driver module 240 are disposed in the housing 210 with discs data processing module 250.In addition, discs pallet 230 is suitable for carrying a discs (not illustrating), and driver module 240 is suitable for driving discs pallet 230 from the opening 210a of housing 210 turnover.In addition, discs data processing module 250 for example be optical read module and optics writing module at least one of them.In other words, discs data processing module 250 can write data in the discs, or reads the stored data of discs.

Please refer to Fig. 2 B and Fig. 2 C, panel 220 is disposed at a side of discs pallet 230, and beam 260 is disposed at the edge of panel 220.When discs pallet 230 was positioned at housing 210, panel 220 covered opening 210a, and beam 260 is between panel 220 and housing 210.For example, beam 260 for example is the lower edge that is disposed at panel 220, yet beam 260 also can be upper limb or other the suitable position that is disposed at panel 220.In addition, the material of beam 260 for example is foam, rubber or the damping material with vibration-absorbing function.

When CD-ROM drive 200 turned round, the beam 260 that is disposed at panel 220 edges can avoid panel 220 and housing 210 to produce collision, to reduce vibrations and the noise that CD-ROM drive 100 is produced when turning round.What deserves to be mentioned is that the utility model also dwindles the slit T2 (shown in Fig. 2 C) between panel 220 and the housing 210.The noise that is sent when in other words, CD-ROM drive 200 turns round just is difficult for passing from slit T2.

With regard to the measurement experiment of noise sound pressure level (sound pressure level), under the situation of carrying disc sheet running, the noise sound pressure level of the CD-ROM drive 200 of present embodiment is about 47.4 decibels, and existing CD-ROM drive is about 47.9 decibels.In addition, under the situation of not carrying disc sheet running, the noise sound pressure level of the CD-ROM drive 200 of present embodiment is about 47.1 decibels, and existing CD-ROM drive is about 47.6 decibels.Based on above-mentioned experimental result, no matter be under the situation of carrying disc sheet running or under the situation of carrying disc sheet running, compared to existing CD-ROM drive, the CD-ROM drive 200 of present embodiment all has lower noise sound pressure level.

[second embodiment]

Fig. 3 illustrates the sectional view according to the CD-ROM drive of the utility model second preferred embodiment.Please refer to Fig. 3, second embodiment is similar to first embodiment, and its difference is: beam 360 is disposed on the inwall of housing 210.When discs pallet 230 was positioned at housing 210, beam 360 was between housing 210 and panel 220.

For example, beam 360 for example is between the lower edge of panel 220 and housing 210 (as shown in Figure 3), yet beam 360 also can be between the upper limb and housing 210 of panel 220.

In sum, CD-ROM drive of the present utility model has following advantage at least:

One, because the utility model is disposed at beam between housing and the panel, produce collision to avoid panel and housing, therefore CD-ROM drive of the present utility model has lower noise and vibrations when running.In addition, CD-ROM drive of the present utility model more increases the width of panel, and dwindling the slot between panel and the housing, so noise in operating is difficult for dispersing out via slot.

Two, under the situation that does not change original outward appearance of product and moulding, CD-ROM drive of the present utility model can satisfy the tonequality requirement of environmental testing.
