Description of drawings
Fig. 1 is a general structure synoptic diagram of the present invention, wherein 1 bass horn, 2 shells, 3 folded formations.
Fig. 2 is the user mode figure of Fig. 1, wherein (height) sound loudspeaker, 4 hinges in 21 SD/MMC card (J2), 22 USB interface (J1), 23 earphone cord jacks, 24 supply hubs, 25 play buttons, 31 volume keys, 32.
Fig. 3 is the circuit block diagram of Fig. 1.
Fig. 4 is the circuit theory diagrams of Fig. 3.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing:
As shown in the figure, this player can be play USB flash disk, SD/MMC card mp3 file, its profile is a semisphere, form by shell 2 and folding folded formation 3, be connected by hinge 4 between shell 2 and the folded formation 3, shell 2 the insides are circuit boards, and there are bass horn 1, SD/MMC card 21, USB interface 22, earphone cord jack 23, supply hub 24, play button 25 and power switch in its surface, (height) sound loudspeaker 32, volume key 31 in folded formation 3 surfaces have.
Principle of work
When opening the machine power switch, the 6V power supply just begins to in-line power, workflow is as follows: the 6V → IC that boosts (MP1540), 9V exports to four the tunnel, wherein two-way is given CPU (master control) U1 power supply, the program of first reader storer U2 the inside after master control powers on, just go for then whether USB flash disk or SD card are arranged, if do not have him with regard to standby (this moment, pilot lamp was for red), if file (USB flash disk is arranged, the SD/MMC card) it just waits for user instruction (user's operation just), this moment, lamp be blue, read song on USB flash disk or the SD card and the MP3 decoding device by inside automatically and was decoded into that audio stream is delivered to earphone or power amplifier comes out sound playing by loudspeaker SP when the user presses the broadcast master control.
Function
Power supply: external 220V power supply 6V power supply adaptor; Support No. 5 dry cells of 4 joints to play.
Medium: USB flash disk, mmc card, SD card.
Played file form: MP3 format file.
Play content: English, Lectures on Special Topics, classical poems, song, opera, cross-talk, essay, storytelling chain broadcast etc.
Sound equipment output: mega bass big gun sound system; Headset output interface.
Adopt the Oriole-I family chip, can be used for designing the sound system that to play the MP3 music on USB flash disk or the SD/MMC card, can be widely used in family's combination audio, automobile audio and computer multi-media sound equipment.This chip has substituted the design proposal of multiple chips in the market with a chips because the integrated level height, makes that system design is significantly simplified, the components and parts cost reduces, the reliability raising, thereby the cost performance of whole sound system is significantly improved.
