The USB driving circuit is connected with the audio/video decoding circuit, the microprocessor circuit can receive or emit data from the USB driving circuit, the received data is sent to the audio/video decoding circuit, and analog audio and video after D/A conversion can be transported to the audio magnification process circuit 12 for amplification or outwards broadcast. The utility model can read audio and video data via the USB interface, decode and display, and the utility model has emitting or receiving function and has the advantage that the wireless audio/video player can accomplish data exchange in same or different machine types and can support direct reading outlay medium audio and video files.
Description
Technical field
The utility model relates to a kind of DVD player, particularly a kind of band USB interface, but the audio and video player of wireless transmission.
Prior art
In actual life, along with development of internet technology with popularize, computers etc. all are equipped with USB interface, wireless transmit receivers such as the infrared ray by the band USB interface, bluetooth can be realized the wireless transmission between the computer, mutually transfer files or play audio/video.The wireless transmit receiver of this band USB interface can only be applied to computer apparatus, and operation is inconvenient, and the user is had relatively high expectations.
On the other hand, the audio and video player of existing family and amusement such as vehicle-mounted can only be realized audio-visual broadcast, transmission by the disc player video disc, can not independent utility on stereo set; Real-life a large amount of mp3 file, audio/video file generally can not directly be play on family's audio and video player, maybe can only the input of the music on walkman or flash memory power amplifier be realized the effect of broadcast by interface., because its capacity is all less, contained music file is limited, wants to play more music, just must be repeatedly down loading updating music file on computers, operation is frequently made troubles to the user.
Technical scheme
The technical matters that the utility model solves is to overcome above-mentioned shortcoming, and a kind of wireless image-sound player with USB interface is provided.
The technical solution of the utility model is: design a kind of wireless image-sound player, it comprises casing, panel, display screen, telepilot, USB interface and operation push-button.Microcontroller circuit links to each other with audio/video decoding circuit, osd circuit, wireless transmit receiver, audio frequency amplification treatment circuit and USB driving circuit respectively; The USB driving circuit links to each other with the audio/video decoding circuit, microcontroller circuit receives or sends data from the USB driving circuit, the data that receive are sent into the audio/video decoding circuit, and the audio frequency and the video that obtain simulating after the D/A conversion are transported to power amplifier or external display is play.
The wireless transmit receiver can be arranged to built-in, also can be arranged to external.
The utlity model has following advantage:
1, tool external radio receiving function joins by USB interface and wireless transmit receivers such as the infrared ray of being with USB interface, bluetooth, can realize exchanges data between the identical machine or between the different machine by emission or receiving function.
2, support directly to read audio frequency and video file on the external storage medium of USB interface.
3, control button and display screen are arranged on the complete machine panel, support the telepilot operation; Support Chinese and English and multi-lingual demonstration (LED/VFD/LCD/OSD);
4, can realize the foolproof i.e. broadcast of promptly inserting; Can realize playing/suspending, stop, a last song, next song, F.F., rewind down or directly choosing control function such as broadcast, for the consumer provides mode of operation simply efficiently.

Embodiment
See also Fig. 1, Fig. 1 circuit theory diagrams of the present utility model, it comprises casing 4, panel 6, display screen 2, telepilot 3, USB interface 5 and operation push-button 1, and microcontroller circuit 8 links to each other with audio/video decoding circuit 10, osd circuit 11, audio frequency amplification treatment circuit 13 and USB driving circuit 9 respectively; USB driving circuit 9 links to each other with audio/video decoding circuit 10, the wireless transmit receiver of USB interface is inserted into the USB driving circuit, microcontroller circuit receives or sends data from the USB driving circuit, the data that receive are sent into the audio/video decoding circuit, the audio frequency and the video that obtain simulating after the D/A conversion are transported to power amplifier or external display is reset.
Referring to Fig. 2, Fig. 2 is the circuit theory diagrams of the another kind of embodiment of the utility model; Compare with circuit theory shown in Figure 1, it is identical substantially, and different is that wireless transmit receiver 7 is external, and it links to each other with USB interface 5, and USB interface and USB driving circuit join.
Illustrate below: if above-mentioned two wireless image-sound player, receive MP3 music by the computer memory storage, just can on the USB interface of computer, plug the transmitter of a band USB interface, MP3 music wireless on the computer is transmitted to external or built-in transceiver of the present utility model receives, handle just the MP3 music to be connected to the broadcast of audio frequency amplification treatment circuit by audio decoder; If play film in the DVD-ROM CD drive have USB interface, can be directly link to each other and realize data transmission and decodes and plays or add mutually inserting the wireless transmit receiver and realizing, just film can be delivered to external display playback by the audio/video decoding processing by line; If play the audio/video file of USB portable hard drive, as long as the USB transmission line of USB hard disk directly is inserted into USB interface on the USB driving circuit.
Fig. 3: be the utility model perspective view, from figure as can be known, display screen 2, receiver of remote-control sytem, USB interface 5, button 2 and switch 15 all are arranged on the panel of casing 4.
