The technical solution of the utility model is achieved in that it comprises casing, its improvements are: described casing is provided with two independently loudspeaker, the main panel top of this casing is provided with at least one USB interface, at least one SD card draw-in groove, and casing main panel bottom is provided with at least one Microphone; Volume adjustment knob, bass adjusting knob, high pitch adjusting knob and microphone volume adjusting knob are being arranged in described two loudspeaker top;
In the said structure, described box house is provided with governor circuit, and this governor circuit is connecting above-mentioned two loudspeaker;
In the said structure, described governor circuit is also connecting a usb circuit, SD card interface circuit and microphone interface circuit, and described usb circuit is connected to USB interface, and described SD card interface circuit is connected to SD card draw-in groove, and described microphone interface circuit is connected to microphone interface;
In the said structure, the main panel top of described casing is provided with a USB interface, a SD card draw-in groove, and casing main panel bottom is provided with two Microphones;
In the said structure, described casing rear portion is provided with a power line, and this power line is connected to above-mentioned governor circuit, and the power line next door is provided with a power switch button;
In the said structure, described casing rear portion also is provided with audio frequency input socket and audio frequency accessory power outlet.
The beneficial effects of the utility model are: one, the utility model adopt the two speaker set-up design, and each loudspeaker has independently cavity, guarantee that distortion is less in the driving situation of Same Efficieney, have overcome the cross modulation of vibrating between two loudspeaker; Two, casing of the present utility model is provided with USB interface and SD card draw-in groove, so that this audio amplifier has the selection of more audio frequency media, has the more vitality of fashion; Three, audio amplifier is provided with Microphone, provides the function of OK a karaoke club ok, so that the utility model has more entertainment effect.
