Abstract
The invention relates to a palm multimedia projector, which comprises a central processor of RK27 series, and is characterized in that the central processor is connected with a projector component IPL512G, a power supply module, a data storage module, a display module, a keyboard input module, a USB interface module and an audio amplifier output module. The palm multimedia projector not only has the function of a palm projector, but also integrates the functions of an MP3, an MP4, a CMMB and an FM, has small volume, is convenient to use, and fully meets the requirements of markets.
Description
Technical field
The present invention relates to a kind of multifunctional digital code product, particularly a kind of palm multimedia projector.
Background technology
Projector mainly contains at present:
1, console mode projector
This is a kind of modal projector, and it generally need place projector by means of a height proper supporting platform.
Brightness will be hanged down, and also emphasizes on the function practicality only to keep necessary function always.This be because, they must reduce or even sacrifice the outfit of some non-essential as much as possible, with weight reduction, it can be placed directly on the ground, need just can directly not use by other stilt, its volume is bigger certainly
2, reflection and transmission convolution projector
Its light source is positioned at the top of transparency, and light has finally formed image by the reflection of transparency, because twice process of light transparency makes its optical density increase one times, the image contrast that projects is big, and color is saturated especially.
Its light source be positioned at transparency below, light sees through transparency and has finally formed image.
Its light source be positioned at equally transparency above, light sees through transparency again after the reflection of the metal film at a chain for binding criminals line lens back side, thereby forms image.Existing reflection has transmission again in its imaging process, therefore is referred to as reflection and transmission convolution projector
3, multi-functional projector
It integrates multiple function, and that is to say that it is not only the platform projector, and be the platform slide projector, also can be the material object display platform.
Yet above-mentioned projector has following shortcoming:
1, volume ratio is bigger
2, power supply need be used the 220V alternating current
3, function ratio is more single, generally can only be used for projection
Needs and external unit (such as computer) cooperated and could use when 4, projector used;
Because the relation of power supply and volume can only be applied in bigger place, space, needing computer simultaneously could use from above some present as can be seen projector.
Summary of the invention
In order to overcome the problems referred to above, the purpose of this invention is to provide a kind of palm multimedia projector, it has realized the palm projection, and is powerful, volume is little, and is easy to use, fully satisfies the demand in market.
The present invention realizes like this, a kind of palm multimedia projector, comprise the central processing unit of RK27 series, it is characterized in that: described central processing unit is connected with projector assembly IPL512G, power module, data memory module, display module, keyboard load module, usb interface module and audio frequency power amplifier output module.
The invention has the beneficial effects as follows that it has realized the palm projection, powerful, volume is little, and cost is low, and is easy to use, fully satisfies the demand in market.

Fig. 2 is the framework synoptic diagram of the embodiment of the invention.
Embodiment
Below in conjunction with drawings and Examples the present invention is described further.
As shown in Figure 1, the invention provides a kind of palm multimedia projector, comprise the central processing unit of RK27 series, it is characterized in that: described central processing unit is connected with projector assembly IPL512G, power module, data memory module, display module, keyboard load module, usb interface module and audio frequency power amplifier output module.
In preferred embodiment of the present invention, as shown in Figure 2, central processing unit of the present invention adopts RK2706 or RK2708, it is the multimedia process chip (ARN7EJC+DSP) of double-core, be mainly used in portable multimedia signal Processing such as MP3, MP4, PMP, can finish MP3, MP4 and play functions such as digital album (digital photo frame), e-book.Wherein said data memory module comprises NAND FLASH, NOR FLASH, SD/T-F CARD.
In order to make full use of system resource, described central processing unit also is connected with digital television module, video output module or radio receiver module: digital television module adopts the CMMB special chip to receive the CMMB signal, send central processing unit after the demodulation to, export by the LCD liquid crystal display; The video output module adopts the chip of CH70 series, finishes the conversion of video signal format; Radio receiver module adopts special-purpose FM chip to receive the FM signal, and exporting to central processing unit behind the FM signal restituted signal, central processing unit is handled the back by earphone or loudspeaker output sound.
In this preferred embodiment, described display module is that the LCD liquid crystal touch screen shows.Described power module comprises lithium battery power supply and charging circuit.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
