Fig. 1 is the block diagram of the solar digital ad playing device that proposes of the present utility model.
Fig. 2 is the Mp3 player hardware theory diagram that has usb host control circuit and usb host interface.
Fig. 3 is the software realization flow figure that has the Mp3 player of usb host control circuit and usb host interface.
Embodiment
Solar digital audio advertisement player is the device of a kind of audio plays in public advertisement.Solar digital ad playing device can be placed on the devices such as billboard, public transport stop board, automatic vending machine on road limit.Utilize sun power as power supply.Ad content can obtain upgrading.When need upgrading, the movable storage device that USB flash disk etc. is had USB interface is connected with solar digital audio advertisement player, operates the content of logarithmic code audio frequency solar advertisement player and upgrades.
Can set the working time to solar digital audio advertisement player, arrive the start time of setting, solar digital audio advertisement player begins playing advertisements, arrives the shut-in time of setting, and solar digital audio advertisement player stops playing advertisements.
As shown in Figure 1, the solar digital audio advertisement player that the utility model proposed comprises solar storage battery 1, time control switch 2, power circuit 3, MP3 player 4, usb host interface 5, usb host control circuit 6 and loudspeaker 7.Wherein solar storage battery 1 links to each other with power circuit 3 through the control of clock switch, and power circuit 3 connects MP3 player 4, and loudspeaker 7 links to each other with power circuit 3, and loudspeaker, MP3 player and power circuit are formed closed loop; MP3 player 4 has Embedded USB host computer control circuit, and a usb host interface that is arranged on the MP3 player 4 links to each other with this Embedded USB host computer control circuit, is used to realize that USB flash disk etc. has the movable storage device of USB interface and the communication between the MP3 player 4.
The course of work of this device is: solar storage battery 1 provides power supply for whole device, time control switch 2 is configured start time and stand-by time, when arriving the start time, time control switch is opened, and provides required power supply by power circuit 3 to other elements.Arrive stand-by time, time control switch 2 disconnects, and stops to provide power supply to other elements.
When needs upgrade content, be connected with usb host interface 5 on the MP3 player 4 by USB flash disk, upgrade by the content of being stored in 6 pairs of mp3 players of usb host control circuit.
Time control switch 2 can be realized by outward element, also can realize by being integrated in surface-mounted integrated circuit.
In order to reach better advertising results, can between the input end and MP3 player 4 of loudspeaker 7, an audio power amplifying circuit be set.
In the description of drawings with implementation in the mp3 player mentioned also can replace with the mp4 player, in order to realize the solar digital audio player.
The Mp3 player that has usb host control circuit and usb host interface, its hardware principle block diagram, as shown in Figure 2: the core cell that has in the Mp3 player of usb host control circuit and usb host interface is little processing 8, it can be realized storer 12 in the mp3 player and digital signal processor 11, and usb host control circuit 6 and D/A change-over circuit 13 carry out input/output signal control, wherein, usb host control circuit 6 connects usb host interface 5, can carry out the data updating of mp3 player by this usb host interface 5, D/A change-over circuit 13 also connects a power amplification element 14, and the transformation result that is used for digital-to-analog signal is amplified; Microprocessor 8 is gone back supervisory keyboard 15, and liquid crystal display 16 is controlled in the peripheral operation input of acceptance and process user simultaneously.Because this partial content is a prior art, therefore, does not do detailed description here, only as the reference of understanding the abundant publicity of technical solutions of the utility model.
