Description

光碟機 CD player

本發明涉及一種光碟機，尤其涉及一種可以減小噪音的光碟機。 The present invention relates to an optical disk drive, and more particularly to an optical disk drive capable of reducing noise.

光碟機通常包括下殼體、上殼體和托盤。下殼體和上殼體相配合形成收容空間。托盤容置於上述收容空間內並將收容空間分為上下兩部分。其中上部分空間由上殼體和托盤圍成；下部分空間由下殼體和托盤圍成。使用時，光碟片位於托盤上且位於托盤和上殼體之間圍成的上部分空間內。這樣，當光碟機讀取光碟時，高速轉動的光碟片會加速氣流運動使氣流紊亂，容易產生振動而引起噪音。 A disc player typically includes 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 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. In use, the disc is located on the tray and is located in the upper portion of the space enclosed between the tray and the upper housing. Thus, when the optical disc player reads the optical disc, the high-speed rotating optical disc will accelerate the airflow to make the airflow disorder, and it is easy to generate vibration and cause noise.

有鑒於此，有必要提供一種可以減小噪音的光碟機。 In view of this, it is necessary to provide an optical disk drive that can reduce noise.

一種光碟機，其包括下殼體、上殼體和托盤；下殼體和上殼體相配合形成收容空間；托盤用於承載光碟片，其位於上殼體和下殼體之間並將收容空間分為上下兩部分；所述托盤上還設有連通上部分空間和下部分空間的通孔。 An optical disc drive comprising a lower casing, an upper casing and a tray; the lower casing and the upper casing cooperate to form a receiving space; the tray is configured to carry a disc, which is located between the upper casing and the lower casing and is to be received The space is divided into upper and lower parts; the tray is further provided with a through hole connecting the upper part space and the lower part space.

使用上述光碟機，上述通孔可引導高速轉動的光碟片產生的氣流從上部分空間流向下部分空間，從而減小因氣流紊亂而引起的振動及噪音。 With the above optical disc drive, the through hole can guide the airflow generated by the high speed rotating optical disc to flow from the upper portion to the lower portion of the space, thereby reducing vibration and noise caused by airflow disturbance.

請同時參閱圖1和圖2，光碟機99包括下殼體100、上殼體200、托盤300及主軸馬達400。請同時參閱圖2至4，下殼體100和上殼體200相互配合可形成收容空間500。托盤300和主軸馬達400均容置於收容空間500內。 Referring to FIG. 1 and FIG. 2 simultaneously, the optical disk drive 99 includes a lower casing 100, an upper casing 200, a tray 300, and a spindle motor 400. Referring to FIGS. 2 to 4 simultaneously, the lower case 100 and the upper case 200 cooperate to form the receiving space 500. Both the tray 300 and the spindle motor 400 are housed in the accommodating space 500.

托盤300用於承載光碟片600。托盤300位於下殼體100和上殼體200之間，且其把收容空間500分為上下兩部分520、510。托盤300遠離出倉口的一端設有多個圓形通孔310，其中，多個圓形通孔310密集間隔的排列於托盤300上。通孔310連通上部分空間520和下部分空間510，並且當光碟片600放置於托盤300上時，光碟片600將通孔310覆蓋。 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 disposed at one end of the tray 300 away from the outlet port, and a plurality of circular through holes 310 are arranged on the tray 300 at a close interval. The through hole 310 connects the upper portion space 520 and the lower portion space 510, and when the optical disk sheet 600 is placed on the tray 300, the optical disk sheet 600 covers the through hole 310.

主軸馬達400用於轉動光碟片600，以實現讀碟操作。 The spindle motor 400 is used to rotate the optical disc 600 to effect a disc reading operation.

使用時，光碟片600固定於主軸馬達400上，且位於上殼體200和托盤300之間。當主軸馬達400帶動光碟片600高速轉動時，高速轉動的光碟片600會加速氣流運動使氣流紊亂。此時，通孔310可以引導上述氣流沿箭頭700所示方向從上部分空間520流向下部分空間510，從而減小上述氣流紊亂而引起的振動及噪音。 In use, the optical disc 600 is fixed to the spindle motor 400 and is 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-described airflow disturbance.
