Abstract
The present invention proposes a kind of wireless K and sings microphone, including microphone, AD conversion unit ADC, reverberation effect unit, downmixing unit, D/A conversion unit DAC, monitor playback unit, wireless connections unit, it is characterized in that, the human voice signal picked up by microphone enters reverberation effect unit after ADC carries out analog digital conversion, reverberation effect unit sends it to downmixing unit after digitized human voice signal is carried out reverberation effect process, wireless connections unit receives the music accompaniment signal sent by mobile terminal and sends it to downmixing unit, human voice signal is carried out mixing and sending audio signal to DAC by downmixing unit with music accompaniment signal, audio signal is exported sound to user by monitoring playback unit after digital-to-analogue conversion, and audio signal or human voice signal can be used bluetooth approach to be sent to mobile terminal by this microphone.By the invention it is possible to the K song effectively promoting user is experienced and high-quality sound share ability.
Description
Technical field
The invention belongs to electroacoustic field, sing microphone particularly to a kind of wireless K.
Background technology
The mobile terminal such as mobile phone, panel computer gradually universal, the network bandwidth constantly promotes, the K of various applicable mobile terminals
Song software is also used by increasing user, is increasingly becoming popular personal entertainment mode；During K song, need wired
Microphone earphone inserts mobile terminal or the mike directly using mobile terminal to carry and speaker, and the former user can be subject to
The constraint of cable is experienced the best, and the latter's then easy echogenicity is uttered long and high-pitched sounds and caused song effect to be deteriorated, and additionally both of which can not realize
The real-time monitoring of voice, makes user lack telepresenc；Although prior art has occurred in that the K using radio connection
Song microphone, but its function singleness, the effect when signal of pickup is wirelessly transmitted back to mobile terminal is the most poor, no
User can be met K song is experienced and the higher pursuit of tonequality.
Summary of the invention
In order to overcome the defect of prior art, the present invention proposes a kind of wireless K and sings microphone, by arranging reverberation in microphone
Effect unit, downmixing unit and monitoring playback unit etc. also use the wireless transmission means being suitable for high quality audio, effectively promote
User K song experience and high-quality sound share ability.
The invention provides a kind of wireless K and sing microphone, including microphone, analog-digital converter ADC, reverberation effect unit, mix
Sound unit, D/A conversion unit, monitoring playback unit, wireless connections unit, it is characterised in that the voice letter picked up by microphone
Entering reverberation effect unit number after ADC carries out analog digital conversion, reverberation effect unit carries out reverberation to digitized human voice signal
Sending it to downmixing unit after effect process, wireless connections unit receives the music accompaniment signal sent by mobile terminal and incites somebody to action
It sends to downmixing unit, and human voice signal is carried out mixing and audio signal being sent extremely by downmixing unit with music accompaniment signal
DAC, audio signal is exported sound to user by monitoring playback unit after digital-to-analogue conversion.
Further, mixed for downmixing unit audio signal is wirelessly returned to mobile by wireless connections unit
Terminal, or, the human voice signal after ADC analog digital conversion is directly returned to mobile terminal by wireless connections unit.
Further, microphone quantity is one or more, downmixing unit according to the demand of user to voice and sound
The mixed proportion of happy accompaniment is adjusted, and monitoring unit is the built-in speaker of microphone, inserts both earphones or two of microphone
Have concurrently.
Further, wireless connections unit includes receptor/transmitter, encoder/decoder.
Further, the wireless connections between microphone and mobile terminal include that bluetooth connected mode, wireless connections unit are adopted
With blue tooth RFCOMM passage by single channel or multichannel audio signal or human voice signal's uplink to mobile terminal, Bluetooth transmission
Code encoding/decoding mode use one of SBC, OPUS, Apt-X, AAC.
Accompanying drawing explanation
Fig. 1 is the system block diagram of the wireless K song microphone of the present invention
Detailed description of the invention
In conjunction with accompanying drawing, the wireless K song microphone of the present invention is described in detail.Accompanying drawing 1 shows the wireless K song of the present invention
Microphone 1 and can carry out the mobile terminal 2 of wireless connections with it, wireless K song microphone 1 includes microphone 11, AD conversion unit
ADC12, reverberation effect unit 13, downmixing unit 14, D/A conversion unit DAC15, monitoring playback unit 16, wireless connections unit
17, microphone 11 human voice signal picked up enters reverberation effect unit 13, reverberation effect list after ADC12 carries out analog digital conversion
Unit 13 sends it to downmixing unit 14 after digitized human voice signal is carried out reverberation effect process, and wireless connections unit 17 connects
Receive the music accompaniment signal that sent by mobile terminal 2 and send it to downmixing unit 14, downmixing unit 14 by human voice signal with
Audio signal is sent to DAC15 after mixing by music accompaniment signal, is exported by monitoring playback unit 16 after digital-to-analogue conversion
Sound, to user, realizes the simulation of true K song scene with this.
Further, mixed for downmixing unit 14 audio signal can wirelessly be returned by wireless connections unit 17
To mobile terminal 2, and can carry out recording and use a network for share by the built-in application of mobile terminal 2；Optionally, wireless company
Human voice signal after ADC12 analog digital conversion also directly can be returned to mobile terminal 2 by order unit 17, mobile terminal 2 enter
The subsequent treatment such as row audio mixing.
Wherein, microphone 11 quantity is one or more；Downmixing unit 14 can according to the demand of user to voice and
The mixed proportion of musical background is adjusted；Monitoring unit 16 be the built-in speaker of microphone 1, the earphone inserting microphone 1 or
Have concurrently both two；Wireless connections unit 17 farther includes receptor, decoder, receives the signal from mobile terminal 2 and goes forward side by side
Row decoding, and encoder, transmitter, carry out the signal from ADC12 or downmixing unit 14 encoding and be sent to move eventually
End 2；Mobile terminal 2 can be mobile phone, panel computer, laptop computer etc.；Microphone can be made as hand-held or Table top type.
As a further improvement on the present invention, the wireless connections between microphone 1 and mobile terminal 2 include bluetooth connected mode,
Wireless connections unit 17 uses blue tooth RFCOMM passage by single channel or multichannel audio signal or human voice signal's uplink extremely
Mobile terminal 2, code encoding/decoding mode uses one of SBC, OPUS, Apt-X, AAC, thus can realize the low delay of uplink, complete
Frequency band and channel transmission, be greatly promoted the fidelity of upward signal；Concrete, the Bluetooth transmission of the present invention can be put down based on CSR
Platform realizes, and is wherein sent RFCOMM channel data to DSP process by the protocol stack processing unit (stack) of CSR platform,
Return protocol stack processing unit (stack) after being disposed, then be transmitted.
