Along with the development of digital audio/video, the multimedia messages of various amusements is more and more, and as CD, VCD, DVD, MP3, JPEG, people will appreciate these multimedia messagess in moving at present, generally adopt portable DVD player.Adopt the shortcoming of this mode to be, the user goes out the provisional capital at every turn will be with many video discs, also need in the time of use frequently to change video disc, so the user use not too convenient.And for example digital camera is more prevalent, but camera focuses on photograph, and playing function and audio frequency and video quality are done generally all poorly, and the memory capacity of memory card is also limited, thus the user use also not too convenient.
Summary of the invention
Purpose of the present invention will provide a kind of portable multimedia player exactly, makes the user can use multimedia messages easily.
When realizing purpose of the present invention, taked following technological means:
In this portable multimedia player, include decoding control device, power amplifier, loudspeaker and earphone, display device, battery, charge and discharge device, hard disk, USB interface device, memory card interface device.
The decoding control device reads information from hard disk, or from memory card, read information by the memory card interface device, carry out audio/video decoding then, the sound signal of output is passed through power amplifier, drive loudspeaker and earphone sounding, the vision signal of output is then carried out image by display device and is shown that wherein the information format that can read and decode comprises CD, VCD, DVD, MP3, JPEG, MPEG-4.
Adopt the IDE bus to connect between USB interface device, decoding control device, the hard disk, between USB interface device and the decoding control device in addition the communication port line be connected.
The USB interface device can be linked computing machine, computing machine can be with the document copying in the computing machine in hard disk by the USB interface device, or with the document copying in the hard disk in computing machine, in this copy procedure, the USB interface device does not operate the decoding control device by the communication port line to the IDE bus data.
The decoding control device can be with the information copy in the memory card in hard disk by the memory card interface device, also can be with the information copy in the hard disk in memory card.
In the present invention, since computing machine can be in player the disk copy file, therefore can be on video disc, digital camera, internet the programme information of CD, VCD, DVD, MP3, JPEG, MPEG-4 form be copied to the player, hard disk with 40G is an example, can deposit about 10 DVD, 70 CD/VCD, MPEG-4, MP3, JPEG are put just manyly, use just very convenient when the user goes on a journey like this.The photo that user's digital camera is clapped generally is placed in the memory card, after the user has taken photo, memory card can be inserted into this device plays, because this device is a special player, therefore playing function and audio frequency and video performance can be done relatively goodly, and because hard-disk capacity is big, so the user can rise the photo files in the memory card in the hard disk, continue photograph with this memory card then, so just greatly facilitate the user.The user can also be used as a portable hard drive to this device and use, so this device serves many purposes when the user goes on a journey, and is very convenient.
Description of drawings
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a circuit block diagram of the present invention.
Embodiment
As Fig. 1, in this portable multimedia player, include decoding control device, power amplifier, loudspeaker and earphone, display device, battery, charge and discharge device, hard disk, USB interface device, memory card interface device.
The decoding control device reads information from hard disk, or from memory card, read information by the memory card interface device, carry out audio/video decoding then, the sound signal of output is passed through power amplifier, drive loudspeaker and earphone sounding, the vision signal of output is then carried out image by display device and is shown that wherein the information format that can read and decode comprises CD, VCD, DVD, MP3, JPEG, MPEG-4.
Adopt the IDE bus to connect between USB interface device, decoding control device, the hard disk, between USB interface device and the decoding control device in addition the communication port line be connected.
The USB interface device can be linked computing machine, computing machine can be with the document copying in the computing machine in hard disk by the USB interface device, or with the document copying in the hard disk in computing machine, in this copy procedure, the USB interface device does not operate the decoding control device by the communication port line to the IDE bus data.
The decoding control device can be with the information copy in the memory card in hard disk by the memory card interface device, also can be with the information copy in the hard disk in memory card.
The memory card that is suitable in the present embodiment comprises SD, SM, MS, CF, MMC, XD.The hard disk that adopts is 2.5 cun 40G, and battery is a lithium battery.And display device adopts TFT or OLED display screen.
Computing machine is connected standard and adopts USB2.0 with the USB interface device, file transfer speed will be faster like this.
In this player course of work, when the USB interface device is linked computing machine, the USB interface device makes the decoding control device enter low-power consumption mode by the communication port line, and turn off display device, power amplifier, loudspeaker and earphone by the decoding control device, power supply is switched to 5V power supply in the USB interface by battery.
If this player is work not, when the USB interface device was linked computing machine, power supply was directly provided by the 5V power supply in the USB interface; The USB interface device makes the decoding control device enter low-power consumption mode by the communication port line, and turns off display device, power amplifier, loudspeaker and earphone by the decoding control device.
Can save the use of battery like this, extend the life of a cell, if the user only is used as a portable hard drive to this player, charged pool can not.
If computing machine after after a while, is not operated this player yet, the USB interface device makes decoding control device control charge and discharge device by the communication port line, utilizes the 5V power supply in the USB interface to be battery charge.Use computing machine like this,, just can be this player battery charge, make the user feel very convenient such as notebook computer.
In the present embodiment, also include a power supply adaptor, it is output as 5V, delivery is the USB connector, 2 data lines wherein are unsettled, and this delivery can be connected with the USB interface device, and the USB interface device will be powered the decoding control device by the communication port line and switched to the 5V power supply of this adapter by battery, under the control of decoding control device, charge and discharge device utilizes the 5V power supply of this adapter to be battery charge.The user is just relatively more flexible for the power supply and the charging modes of this player like this.
In the present embodiment, the decoding control device also is connected with hand input device, and the user can be provided with folder name or filename in the hard disk by this hand input device.The filename that generates owing to digital camera generally is by sequence number, and is very not directly perceived, therefore by this function, just can be according to user's custom changed name, and the user just searches and makes things convenient in the extreme like this.
In the present embodiment, decoding control device can decode simultaneously image file and music file in the hard disk, the vision signal relevant with image file of output carried out image by display device and shown, the sound signal relevant with music file of output drives loudspeaker and earphone sounding then by power amplifier.Like this, when the user appreciates photo, simultaneously music appreciating and song, the vision and the sense of hearing have all obtained enjoyment simultaneously, thereby have avoided dull shortcoming.
