Description of the Invention: [Technical Field of the Invention] The present invention relates to an optical disk drive, and more particularly to an optical disk drive capable of reducing noise. [Prior Art] [0002] A disc player generally includes a lower case, an upper case, and a tray. The lower case and the upper case cooperate to form a receiving space. The tray is placed in the above-mentioned accommodating space and divides the accommodating space into upper and lower parts. The upper part of the space is enclosed by the upper casing and the tray; the lower part of the space is enclosed by the lower casing and the tray. When in use 〇 , the disc is located on the tray and is located in the upper space enclosed between the tray and the upper casing. Thus, when the optical disk drive reads the optical disk, the high-speed rotating optical disk accelerates the airflow to make the airflow turbulent, which is prone to vibration and causes noise. SUMMARY OF THE INVENTION [0003] In view of the above, it is necessary to provide an optical disk drive that can reduce noise. [0004] An optical disc drive comprising a lower housing, an upper housing and a tray; the lower housing and the upper housing cooperate to form a receiving space; the tray is configured to carry a disc, which is located in the upper housing and the lower housing The compartment is divided into upper and lower parts; the tray is further provided with a passage connecting the upper part space and the lower part space. [0005] With the above-described optical disk drive, the above-mentioned through hole can guide the air current generated by the high speed rotating optical disk to flow from the upper portion to the lower portion of the space, thereby reducing vibration and noise caused by the turbulence of the air flow. [Embodiment] [0006] Please refer to FIG. 1 and FIG. 2 at the same time, the optical disk drive 99 includes a lower casing 100, an upper casing 099113345, a form number A0101, a third page, a total of 10 pages 0992023550-0 201137870 200, a tray 300 and a spindle motor 400. 2 to 4, the lower case 100 and the upper case 200 cooperate to form the accommodating space 500. Both the tray 300 and the spindle motor 400 are housed in the accommodating space 500. The tray 300 is used to carry the optical disc 600. The tray 300 is located between the lower casing 100 and the upper casing 200, and divides the accommodating space 500 into upper and lower portions 520, 510. A plurality of circular through holes 310 are provided at one end of the tray 300 away from the discharge port. The through hole 310 connects the upper portion space 520 and the lower portion space 510. The spindle motor 400 is used to rotate the optical disc 600 to implement a disc reading operation. In use, the optical disc 600 is fixed to the spindle motor 400 and located between the upper housing 200 and the tray 300. When the spindle motor 400 drives the optical disc 600 to rotate at a high speed, the high-speed rotating optical disc 600 accelerates the airflow to confuse the airflow. At this time, the through hole 310 can guide the airflow to flow from the upper portion space 520 to the lower portion space 510 in the direction indicated by the arrow 700, thereby reducing vibration and noise caused by the above airflow disorder. [0010] In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
