Brief description of the drawings
Fig. 1-2 is the structural representation of the integrated two-sided control circuit board of USB power supply audio amplifier wire rod with bluetooth and power amplifier described in the utility model; In figure, 1, control circuit board; 2, LED light; 3, the three-position switch of bluetooth and the conversion of AUX IN audio frequency input pattern; 4, Bluetooth function button; 5, USB feeder ear; 6, AUX IN audio input end; 7, left and right acoustic channels audio output; 8, bluetooth IC; 9, microphone link; 10, power discharging IC; 11, volume control potentiometer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described, if Fig. 1 is the structural representation of the integrated two-sided control circuit board of USB power supply audio amplifier wire rod with bluetooth and power amplifier described in the utility model, as shown in the figure, a kind of integrated two-sided control circuit board for the USB speaker wire rod with bluetooth and power amplifier, comprise control circuit board 1, the end face of described control circuit board 1 is provided with a LED light 2, the three-position switch 3 of bluetooth and the conversion of AUX IN audio frequency input pattern, a Bluetooth function button 4, USB feeder ear 5, AUX IN audio input end 6, left and right acoustic channels audio output 7, the bottom surface of control circuit board 1 is provided with a power discharging IC 10, a bluetooth IC8, on the bottom surface of control circuit board 1, be also provided with a microphone link 9 and volume control potentiometer 11.Wherein, described control circuit board 1 bottom surface is provided with crystal oscillator, resistance, electric capacity, the inductance of coupling relative to bluetooth IC8 function power discharging IC 10; Described left and right acoustic channels audio output 7 can be connected with two loudspeaker on audio amplifier by two pairs of audio output lines; Described AUX IN audio input end 6 can connect by electric wire a DC3.5 plug or a pair of RCA lotus flower head of audio frequency input; Described USB feeder ear 5 can connect USB A male end; In described control circuit board 1, be also provided with power amplifier.
In the technical program, the left and right acoustic channels audio output on control circuit board can be connected on two loudspeaker of audio amplifier by two pairs of audio output lines; USB feeder ear connects USB A male end, and after A male end is plugged the USB port of 5V, control circuit board just obtains needed power supply; AUX IN audio input end connects a DC3.5 plug or a pair of RCA lotus flower head of audio frequency input by electric wire; This product being mixed to shell just can work after assembling again.Due to built-in power amplifier in control circuit board and be connected with the loudspeaker of two audio amplifiers by left and right acoustic channels audio output, so audio amplifier inside does not need to install in addition power amplifier plate.In the time that fixed equipment uses the design's audio amplifier as computer, TV, Bluetooth audio frequency input on control panel is toggled it to the switch of AUX IN input " AUX IN " mark one end, in the time that the mobile devices such as mobile phone, panel computer, notebook computer use the design's audio amplifier, this switching toggle is arrived " bluetooth " one end.If need to take on the telephone in the time that mobile phone is using the design by bluetooth audio plays, that Bluetooth function button can be realized and the function such as answer, refuse to listen, hang up, and in the time of audio plays, Bluetooth function button can be realized the functions such as broadcasting, time-out.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art have all embodied principle of the present utility model to some variations that wherein some part may be made, within belonging to protection domain of the present utility model.
