CN201174244Y - Portable blue light music player - Google Patents

Abstract

The utility model relates to a portable blue ray music player which comprises a shell, a CD player mainboard provided with a servo interface, a blue ray sound pickup device and a servo system connected with the blue ray sound pickup device; the servo system connected with the blue ray sound pickup device is connected with the servo interface on the CD player mainboard; and the blue ray sound pickup device and the CD player mainboard are arranged inside the shell. The portable blue ray music player has the advantages that blue ray is the most advanced large-capacity disk format; the great advancement of the BD laser technology can make you store a 250 GB document file on a single disk, which is five times of the prior DVDs (a single disk). A blue ray disk has an extraordinarily firm layer surface, can protect an important record layer in the disk and stand the frequent uses, fingerprint, scratch and dirt, thereby ensuring the storage quality and data security of a blue ray product.

Description

The portable blu-ray music player

Technical field

The utility model relates to a kind of music player, particularly a kind of portable blu-ray music player.

Background technology

Tradition DVD needs shaven head to send red laser (wavelength is 650nm) to read or write data, and its weak point is a record or to read information capacity little, and the storage document files can only reach 5 GB on the single dish, and the tonequality of playing is relatively poor.

Summary of the invention

In view of the deficiency that prior art exists, the utility model provides a kind of portable blu-ray music player that utilizes the present popular blue light technology that is in scientific and technological forward position to combine with portable CD music player technology.

The technical scheme that the utility model is taked for achieving the above object is: a kind of portable blu-ray music player, comprise casing, be provided with the CD Player mainboard of servo interface, it is characterized in that: also comprise blue light acoustic pickup and the servo-drive system that is connected with the blue light acoustic pickup, the servo-drive system that described blue light acoustic pickup connects is connected with the servo interface on the CD Player mainboard, and described blue light acoustic pickup and CD Player mainboard are with placing in the casing.

The beneficial effects of the utility model are: blue light is state-of-the-art high capacity disc format meant, and the huge advance made of BD laser technology makes you can store the document files of 25GB on a single dish, 5 times of this (single dish) DVDs that is existing.On speed, blue light allows 1 to 2 times of writing speed of per second 4.5 to 9,000,000 in other words; Blu-ray Disc has a unusual firm aspect, can protect the important recording layer in laser disc the inside, can withstand frequent use, fingerprint, scratch and dirt, guarantees the storage qualitative data safety of blue light product with this; Technically, the blue light recorder system can the compatible various optical disc products that occur before this; Utilize the characteristics of the high storage capacity of the portable characteristics of original CD music player and blue light technology, bring the super refreshing enjoyment of a kind of high power capacity of people, high definition.

Embodiment

Below in conjunction with the drawings and specific embodiments this patent is described in detail.

As shown in Figure 1, 2, a kind of portable blu-ray music player, comprise casing, be provided with the CD Player mainboard of servo interface, also comprise blue light acoustic pickup and the servo-drive system that is connected with the blue light acoustic pickup, the servo-drive system that the blue light acoustic pickup connects is connected with the servo interface on the CD Player mainboard, and the blue light acoustic pickup and the CD Player mainboard that are connected with servo-drive system place in the casing together.

The portable blu-ray music player mainly is made up of laser sound pickup and disc record system, servo-drive system, signal processing system, information storage system and control system etc.Laser sound pickup is the critical component of player, and it is made up of semiconductor laser, optical system and photodetector.Laser instrument is a miniwatt (MW level) AIGAS laser diode, the laser beam of sending projects on the information faces of disc by optical lens system, owing to write down many pits on the disc, therefore, when the blue light luminous point is beaten at pit, because of reflected light a little less than, the signal that photoelectric detector is picked up is little; When luminous point is beaten on the aluminium film at no pit, reflected light is stronger, the signal that Photoelectric Detection is picked up is big, corresponding like this having of pit, there is not the electric impulse signal that just produces corresponding high-low level in the output of detecting device, pass through the RF amplifier then, obtain the serial digital signal of " 1 " and " 0 " by its internal comparator, and be added to digital signal and treatment circuit, carry out that demodulation, frame synchronizing signal detect, correction process etc., data after handling are added to digital to analog converter (D/A), become the sound number output of simulation with regard to transducer.

(Blu-ray Disc) is the same with floppy disk and hard disk for Blu-ray Disc, also can be with the form canned data of binary data (data pattern of being made up of " 0 " and " 1 ").To on CD, store data, at first must data-switching be become scale-of-two by computer, with blue laser data pattern is burnt then and be engraved on the disc flat, that have reflection potential the pitting representative " 1 " that laser carves, blank space representative " 0 " on disc.In reading of data on Blu-ray disc, directional beam (laser) moves rapidly on the surface of CD.The compact disc player of reading of data can be observed each point of laser process from the CD, to determine its whether reflector laser.If it is reflector laser (there have a pitting) not, computer just knows that it represents one " 1 " so.If laser is reflected, computer just knows that this point is one " 0 ".Then, these thousands of or millions of " 1 " and " 0 " are reverted to music by compact disc player again.Utilize the characteristics of the high storage capacity of the portable characteristics of original CD music player and blue light technology, bring the super refreshing enjoyment of a kind of high power capacity of people, high definition.

Claims (1)

1, a kind of portable blu-ray music player, comprise casing, be provided with the CD Player mainboard of servo interface, it is characterized in that: also comprise blue light acoustic pickup and the servo-drive system that is connected with the blue light acoustic pickup, the servo-drive system that described blue light acoustic pickup connects is connected with the servo interface on the CD Player mainboard, and described blue light acoustic pickup and CD Player mainboard are with placing in the casing.
