Abstract
The invention discloses a universal serial bus (USB) and secure digital (SD) card type player. The player comprises a power connector, a display, a player shell, and a power switch key, a microphone socket, an auxiliary AUX audio input socket, a key, an SD card interface, a USB interface and more than one control knob which are arranged at the front end surface of the shell, and also comprises a balanced XLR volume output socket, a sound output socket and an external liner audio input socket which are formed in the rear end surface of the shell, as well as a circuit board arranged inside the shell; the circuit board comprises a master control microprogrammed control unit (MCU), a display circuit, a power supply circuit and a power amplifier circuit; the signal end of the master control MCU is connected with an audio decoding integrated circuit (IC) signal end, an audio decoding IC is respectively connected with the USB interface and the SD card interface. The player simultaneously comprises the USB interface and the SD card memory interface, so that the application range of the player by a user is relatively wide, and the memory is automatically identified and judged, and reminded on a display screen terminal, so that the operation is relatively easy and relatively visual.
Description
Technical field
The present invention relates to a kind of USB of holding concurrently and SD card player, belong to player field.
Background technology
At present, some that occur on market can be changed the audio playing apparatus of memory device, this equipment can connect extraneous storer as USB flash disk or SD card, user just can deposit music file and carry in USB flash disk or SD card, this has just solved under without computing machine place, user want to listen self in straitened circumstances with music file.But its weak point is: existing player, only has an external memorizer interface, as only have USB interface or SD card interface, this just makes some audio playing apparatus that only have SD card interface can not play the song of USB flash disk the inside, and the audio playing apparatus that only has USB interface cannot be play the song in SD card, cannot meet popular demand, particularly all the more so in some common application occasions.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of usable range extensively, different audio effects can be set, and there is professional balance output, and the player of bright display window.
For solving technique scheme, the present invention adopts following technical scheme: a kind of USB and SD card player of holding concurrently, comprise power connector, display and player casing, and be arranged on the power switch button on housing front end face, microphone socket, auxiliary AUX audio frequency input socket, button, SD card interface, USB interface and more than one control handle, and be arranged on the balanced type XLR volume output socket of housing rear end face, voice output socket and external linear audio input socket, and be arranged on the circuit board in housing, this circuit board comprises main control MCU, display circuit, power circuit, power amplifier, described main control MCU signal end is connected to audio decoder IC signal end, audio decoder IC respectively with USB, SD interface connects.
Further, described USB, SD interface and USB, SD external memory storage match.
Further, described main control MCU is connected to respectively SD card interface, USB interface, power switch button, microphone socket, auxiliary AUX audio frequency input socket, button, control handle, balanced type XLR volume output socket, voice output socket and external linear audio input socket by circuit board upper conductor.
Further, described button comprises that USB/SD switches options button, EQ effect control button, STOP control button, PLAY control button, PREV IOUS TRACK control button, NEXT TRACK control button and music circulation control button.
Further, described control handle comprises microphone volume control handle, auxiliary external audio frequency/MP3 volume control knob, rear end external audio frequency volume control knob, master volume control handle, high pitch control handle and bass control handle.
The invention has the beneficial effects as follows: pass through technique scheme, be connected to audio decoder IC signal end by main control MCU signal end, audio decoder IC is connected with USB, SD interface respectively, two kinds of different use-patterns of this player have been realized, the usable range that makes user more extensively and storer automatically identify judgement, and at display screen terminal notifying, make operation simpler, directly perceived.
Accompanying drawing explanation
For ease of explanation, the present invention is described in detail by following specific embodiment and accompanying drawing.
