Dustproof portable CD

Abstract

The invention discloses a dustproof portable CD. An outer part of a transparent CD housing (1) is provided with a button groove (2), the lower part of which can be used for direct control over a laser probe (3). The laser probe (3) and a battery groove (6) are separated from each other, and at the same time, an optical disc (9) is directly clamped on a central disk (10) in a sleeved manner. The central disk (10) is connected with an inner side of an opening device (4). The dustproof portable CD is advantageous in that the transparent CD cover can be used to wrap the device body, and then the dust can be prevented from entering the device body, when the front side of the device is arranged on the top; according to the reader structure design, the battery and the laser probe are separated from each other to form a dustproof and anti-electromagnetic structure; the elastic outer ring housing has the anti-breaking and anti-collision function, and the buffering effect can be provided; the isolated rotating disk ring can be used to prevent the scratching caused by the touching of the hands; and the opening device can be used to open the CD cover and the CD easily.

Description

technical field [0001] The invention relates to a portable CD player, in particular to an integral dustproof structure and an elastic anti-drop component. Background technique [0002] The CD player is actually the CD player we often say in our daily life, and some people call it a CD player or a CD player. It is an intelligent high-fidelity stereo audio equipment controlled by a microcomputer. It adopts advanced laser technology, digital technology, computer technology and various new components. It has high-density recording and long playback time (up to 60~75 minutes) ), easy to operate, quick song selection, etc. It can reproduce the recorded content realistically, with clear layers and a sense of presence. Its audio technology index is very high, the dynamic range is large, the frequency response width is 5~20000Hz, and the distortion is as small as 0.003%. At present, CD players are already very common audio playback equipment, and can be divided into two types: des...

AI Technical Summary

Problems solved by technology

There are a lot of gaps between the cover and the base, but it is easy for dust to enter

[0006] The second is that the circle in the middle is very easy to wear and tear, even if you wipe it with a facial tissue as if cherishing it, such an action may leave a long-term mark on it

[0007] Third, the tooth sound is louder after the collision

[0008] Fourth, the design of various switches is unreasonable, and it is easy to press by mistake. Some switches with shell protection are inconvenient to open when in use.
