Abstract
The utility model relates to a computer which can unload the operating system to play the audio document, comprising an optical storage, wherein the optical storage is connected with a +5 and a +12V awaiting voltage power supply inputs which are independent to a main power supply of a computer mainframe; the optical storage is provided with a hardware decoder of the audio document; a decoding output of the hardware decoder of the audio document is connected with the sound system through an audio interface; and the audio signal exported by the hardware decoder and the audio signal exported by a mainboard audio chip are exported to the sound system through the audio interface. After the computer of the utility model is opened and loaded the system, the optical storage can be used as a common optical storage; but if the mainframe power supply is not opened, after inserting the audio file format disks such as the CD and the MP3, the user can press the playing key and play the audio document, thereby hearing the music.
Description
Technical field:
The utility model belongs to the computer equipment technical field, relates in particular to the hardware device of energy displaying audio file.
Background technology:
Existing P C only powers up at computer, after operating system loads, just can carry out the audio file broadcast by moving certain a voice playing software, appreciates music such as CD or MP3.Therefore, people be often just in order audio file such as will to listen to the music, and stand very long wait process.
Summary of the invention:
The purpose of this utility model provides a kind of computer that can not load operation system plays audio file, makes the user can be after putting into CD or MP3 disc, and only need press " PLAY " button just can listen to beautiful music.
The technical solution of the utility model is as follows:
A kind of computer that can not load operation system plays audio file is provided with optical memory, described optical memory be connected to be independent of the host computer primary power+5 ,+input of 12V standby voltage source; Described optical memory is connected with the audio file hardware decoder; The decoding output of described audio file hardware decoder is connected with sound system by the audio interface.The sound signal of the sound signal of hardware decoder output and the output of mainboard audio chip outputs to sound system by the audio interface.
Above-mentioned computer that can not load operation system plays audio file, described audio file hardware decoder are built in the optical memory or the IDE winding displacement by 40/80-Pin is connected with optical memory.
Above-mentioned computer that can not load operation system plays audio file, described audio hardware demoder can also be decoded to video file, its pcb board is provided with two VGA interfaces, one connects display, another connects display card, to realize the just function of energy playing video file of not load operation system.During not load operation system, the vision signal of hardware decoder decoding outputs to display and shows; During the load operation system, the vision signal of display card output outputs to the VGA interface that connects display card on pcb board, and outputs to display by the VGA interface that connects display and show.Such structure, when start load operation system, shows signal is exported from video card; And when not starting shooting playing video file such as VCD, DVD, vision signal is then exported from hardware decoder.
Host computer of the present utility model, after the start loading system, optical memory can be used as a normal optical storer and uses, and promptly utilizes it to read various discs under operating system, uses various playout softwares.If but do not open host power supply, and behind the disc such as CD, MP3 insertion with audio file formats, press play button, get final product displaying audio file, as hearing music.
Description of drawings:
Fig. 1 is the logical schematic of not load operation system plays audio file
Fig. 2 is the hardware decoder structural representation
Fig. 3 is the mainboard structure synoptic diagram
Among the figure, 1-optical storage media, 2-optical memory, 3-hardware decoder, 4-display, 5-power amplifier, 6-audio amplifier, 7-mainboard, 8-connection optical memory ide interface, 9-connection mainboard ide interface, 10-audio interface, 11-connection display card VGA interface, 12-connection display VGA interface, 13-mainboard audio chip interface, 14-respectively connect two ide interfaces of hard disk and decoding deck.
Embodiment:
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of host computer of not load operation system plays audio file, comprise optical memory 2, described optical memory 2 has audio file hardware decoder 3, and this hardware decoder 3 carries out communication by IDE winding displacement and the optical memory 2 of 40/80-Pin; The sound signal of the sound signal of hardware decoder 2 outputs and the output of mainboard audio chip outputs to power amplifier 5 by audio interface 10 and 13 respectively, outputs to audio amplifier 6 again.
Hardware decoder ide interface 8 connects optical memory 2, and another ide interface 9 of hardware decoder connects mainboard ide interface 14.
Hardware decoder 3 can also be decoded to video file, and its pcb board is provided with two VGA interfaces 11 and 12, and VGA interface 11 connects display, and another VGA interface 12 connects display card, to realize the just function of energy playing video file of not load operation system.During not load operation system, the vision signal of hardware decoder decoding outputs to display by VGA interface 11 and shows; During the load operation system, the vision signal of display card output outputs to the VGA interface 12 that connects display card on pcb board, and outputs to display by the VGA interface that connects display and show.Such structure, when start load operation system, shows signal is exported from video card; And when not starting shooting playing video file such as VCD, DVD, vision signal is then exported from hardware decoder.
