[specific embodiment]
The structure of embodiment of the present invention microphone system and principle as shown in Figure 1 to Figure 3, including audiogenic device, mike,
FM reception device, tone playing equipment and the second tone playing equipment.
As shown in Fig. 2 mike includes CPU, display screen, keyboard, pickup module, Audio Input Modules, audio effect processing mould
Block, dio Output Modules and FM transmitter module, the outfan of keyboard and the input of display screen meet CPU respectively.Pickup module
The outfan of outfan and Audio Input Modules connects the input of audio effect processing module respectively；The outfan of audio effect processing module divides
Do not connect the input of FM transmitter module and the input of dio Output Modules, the control end of audio effect processing module and FM transmitter module
Control end connect the outfan of CPU respectively.
The output of audiogenic device terminates the input of the Audio Input Modules of mike.The FM transmitter module of mike and FM
Reception device wirelessly connects, and the output of FM reception device terminates the input of tone playing equipment；The input termination Mike of audiogenic device
The outfan of wind audio effect processing module.The input of the second tone playing equipment terminates the outfan of microphone audio output module.
As shown in figure 3, FM reception device includes MCU, FM receiver module, volume module and dio Output Modules；FM receives
The output of module terminates the input of volume module, and the output of volume module terminates the input of dio Output Modules；FM receives
The control end of the control end of module, the control end of volume module and dio Output Modules connects the outfan of MCU respectively；FM receives mould
Block is wirelessly connected with the FM transmitter module of mike, and the output of dio Output Modules terminates the input of tone playing equipment.
As shown in figure 1, the background music that K sings is passed to the audio effect processing module of mike, pickup module by audiogenic device
The acoustical signal singing people is passed to audio effect processing module.Background music and human voice signal are uniformly processed by audio effect processing module
Afterwards, it is delivered separately to audiogenic device, tone playing equipment, and FM transmitter module.
The audio effect processing module of mike passes to the signal of audiogenic device, is the recording work(in order to realize audiogenic device
Energy.If audiogenic device does not possess sound-recording function, need not transmit.
The audio effect processing module of mike passes to the signal of tone playing equipment, is that is, user can in order to realize singing in real time
To be sung while listening the singing effect of oneself by other tone playing equipment such as earphone.
Audio effect processing module passes to the signal of FM transmitter module, is to realize radio microphone, by real-time singing effect
It is sent to FM reception device, FM reception device can be that the FM shown in this Fig. 3 receives box or other FM receiving device.
After the audio signal that FM transmitter module passes over is retrieved and received to FM reception device in the present invention, then by sound
Frequency signal transmission is to tone playing equipment (such as audio amplifier, television set etc.).
As shown in Fig. 2 the mode of operation of user is passed to CPU by the Keysheet module of mike, CPU is according to Keysheet module
Input, controls audio effect processing module, FM transmitter module respectively, and display screen.

The volume parameters of module.MCU controls whether dio Output Modules export and select the parameters such as output interface.
FM receiver module is controlled after its frequency and sensitivity parameter by MCU, receives the FM signal that mike sends over,
And modulate signals into out audio signal.Then audio signal is passed to volume module.Volume module controls volume parameters through MCU
Afterwards, audio signal is passed to dio Output Modules.Dio Output Modules control whether after output and output interface through MCU, will
Signal transmission is gone out.
The microphone system of above example of the present invention increased FM on the basis of traditional K song microphone system and receives dress
Put, FM reception device not only possesses the function that automatic search K sings the frequency of FM transmitter module in mike, has been also equipped with sound simultaneously
Frequency fan-out capability.Solve the problems, such as that traditional K sings mike and could can only sing in the environment possessing FM reception, it is to avoid because of
Part FM receiving device signal difference and produce cannot normally K song problem.Meanwhile, multi-functional audio effect processing module, and
Can independent regulation sound effect parameters so that user can customized oneself K song style.
