Utility model content
The utility model is in order to solve the above technical problems, provide a kind of mobile phone recording microphone wind based on DSP, using number
Word DSP treatment technologies, can anti-miaow, strengthen power amplifier effect, can also coordinate mobile phone record K song, it is more practical and convenient.
The technical solution adopted in the utility model is as follows, a kind of mobile phone recording microphone wind based on DSP, Mike's bellows chamber
Include DSP process circuits, miaow head, Audio Input Modules, the first power amplifier, the second power amplifier, the 3rd power amplifier, the 4th work(
Discharge road, recording module and ear-piece output, and the miaow head is sequentially connected after the first power amplifier, the second power amplifier and connected
The input of DSP process circuits, Audio Input Modules connect the input that DSP process circuits are connected after the second power amplifier, institute
It is connected after output end the 3rd power amplifier of connection for stating DSP process circuits with recording module, the output end of the DSP process circuits
It is connected after connecting the 4th power amplifier with ear-piece output.
Preferably, the microphone also include bluetooth module, the bluetooth module be connected with the second power amplifier after with DSP
The input connection of process circuit.
Preferably, the microphone also include the 5th power amplifier and UHF transmitter modules, the DSP process circuits it is defeated
It is connected after going out the 5th power amplifier of end connection with UHF transmitter module ear-piece outputs.
Preferably, the power amplifier uses 4809IC chips.
The utility model has advantageous effect in that：The utility model includes DSP by above technical scheme, microphone
Process circuit, miaow head, Audio Input Modules, the first power amplifier, the second power amplifier, the 3rd power amplifier, the 4th power amplifier electricity
Road, recording module and ear-piece output, user voice can be extracted by miaow head, Audio Input Modules connection mobile phone, earphone output
End connection monitoring headpone, can coordinate the APP recording K songs on mobile phone, and user voice passes through the first power amplifier and the second power amplifier electricity
Road is acted on and DSP process circuit digitized processings, and the sound of mobile phone input is by the effect of the second power amplifier and DSP process circuits
Digitized processing, sound passes through landscaping treatment, and monitoring headpone can monitor K song effects, and K songs can be acted on by the 3rd power amplifier
Recording, K song recording records to being shared inside mobile phone, the utility model can anti-miaow can strengthen and improve power amplifier effect, sound is recorded
Effect processed is good.
