Detailed description of the invention
Fig. 1 is a kind of schematic diagram for WIFI speaker that the utility model embodiment provides.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
It is a kind of schematic diagram for WIFI speaker that the utility model embodiment provides, the WIFI speaker referring to Fig. 1, Fig. 1 It is decoder 2 and the main controller 1, described including main controller 1, decoder 2, audio output module 3 and voice input module 4 Audio output module 3 is connected, and the decoder 2 is also connected with voice input module 4;
The main controller 1 includes micro-control unit (MCU) and WIFI module, and the main controller with external WIFI for setting It is standby to be wirelessly connected;
The decoder 2 includes D/A conversion unit and AD conversion unit, and the D/A conversion unit is used for institute The digital audio and video signals for stating main controller output are converted into analog audio signal, and will analog audio signal that conversion obtains export to The audio output module, the analog audio signal that the AD conversion unit is used to export the voice input module are converted For digital audio and video signals, and the digital audio and video signals that conversion obtains are exported to the main controller;
The audio output module 3 includes that power amplification unit and the loudspeaker being connected with the power amplification unit (are raised Sound device), for example, the power amplification unit can be NS4159 power amplifier chips, it can self-demarking code in future by power amplification unit Output to loudspeaker play after the audio signal amplification of device;
Voice input module 4 is for obtaining user speech information, for example, the voice input module may include microphone;
Wherein, digital audio and video signals can be transmitted by IIS bus (i.e. I2S bus) between decoder 2 and main controller 1, For example, main controller 1 can be the 88WM302 chip of Marvell company comprising WIFI module and the part MCU are internally integrated WIFI communication protocol that 802.11b/g/n is wireless, is also integrated with TCP/IP network protocol, supports wireless STATION/AP mode, solution Code device 2 can be ES8316 audio chip, and internal includes the AD conversion unit of one 24,8 to 96KHz sample frequency And one 24,8 D/A conversion units (DAC) for arriving 96kHz sample frequency, the AD conversion unit are used for speaking to oneself The analog audio signal of sound input module is converted to the digital audio and video signals for meeting IIS bus output format, then total by IIS This digital audio and video signals of bundle of lines send main controller to, which is used to pass through master is carried out by IIS bus The digital audio and video signals come export after being converted into analog audio signal to audio output module, specifically, ES8316 audio chip Master control/from control serial data interface by IIS bus connect main controller 1 data-interface, ES8316 audio chip it is linear Simulation input interface connects voice input module 4, in addition, the control terminal of main controller 1 also passes through iic bus (i.e. I2C bus) even It is connected to the control terminal of decoder 2, so as to carry out parameter configuration and job control (as controlled to decoder 2 using main controller System starts to work and stops working);
