Accompanying drawing explanation
Fig. 1 is the general structure block diagram with the wireless blue tooth sound system of portable power source function of the present utility model.
Embodiment
Below with reference to the drawings and specific embodiments, the utility model is described in further details:
Embodiment 1:
As shown in Figure 1, a kind of wireless blue tooth sound system with portable power source function, comprises main body module and charging module;
In described main body module, Tf card, SD card and USB interface, FM radio reception module, external audio input module and key circuit are all connected with master control decoding chip, and the output signal of bluetooth module is input in master control decoder module after operational amplifier amplifies; Master control decoding chip is also connected with two loudspeaker units with R channel power amplifier by L channel power amplifier respectively;
In described charging module, external charging interface, lithium battery charging management circuit, lithium battery, booster circuit and USB external charging circuit are connected successively; Lithium battery is described main body module power supply;
Described lithium battery charging management circuit adopts BT4056 chip; Described booster circuit adopts BT2182 chip; Described master control decoding chip adopts VS1003 chip, and described bluetooth module adopts BT1207S chip.
Open state Bluetooth system is during in bluetooth mode, when external audio input signal connecting system, master control decoding chip automatically disconnects bluetooth to be switched to external audio input pattern without any button operation, when outside TF card inserts, master control decoding chip automatically pattern disconnection is before switched to TF card play mode without any button operation, everything is by the hardware circuit Based Intelligent Control of master control decoding chip inside, without any software, do not relate to any method.
External charging interface selects MICRO USB interface to introduce external power source; Using Charge Management IC BT4056 to realize charging controls, BT4056 is that a complete single-unit lithium ion battery just has constant current, the linear charging of constant voltage IC., its inside has adopted PMOSFET framework, add anti-down charging circuit, hot feedback can automatically adjust to charging current, to chip temperature is limited under high-power operation or high ambient temperature condition; The BT2182 IC that boosts has boost function, overcurrent protection, overload protection, under-voltage locking, overheat protector.
VS1003 is MP3/WMA/MIDI audio decoder and the ADPCM coding chip of a single-chip of being produced by Dutch VLSI company, it has the dsp processor core VS_DSP of a high-performance low-power-consumption, the instruction RAM of 5K, the data RAM of 0.5K, the control of serial and Data Input Interface, 4 universal I/O ports, a UART mouth; Simultaneously in sheet with the ADC of a variable sampling rate, stereo DAC and audio earphone amplifier.VS1003 receives the bit stream of input by a serial line interface, it can be used as the slave of a system.The bit stream of input is decoded, by a numeral, is then that controller arrives one 18 over-sampling multidigit ε-Δ DAC unexpectedly.
