A kind of wireless K sings microphone earphone
Technical field
The invention belongs to electroacoustic field, sing microphone earphone 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, and the K song software of various applicable mobile terminals is also by increasingly Many users are used, and are increasingly becoming popular personal entertainment mode；During K song, need to insert wire microphone earphone mobile terminal or straight Connecing the mike and speaker using mobile terminal to carry, the former user can be experienced the best by the constraint of cable, and the latter's then easy echogenicity is uttered long and high-pitched sounds Causing song effect to be deteriorated, additionally both of which can not realize the real-time monitoring of voice, makes user lack telepresenc；Although prior art has occurred The K using radio connection sings microphone, but its function singleness, the signal of pickup is wirelessly transmitted back to effect during mobile terminal The most poor, it is impossible to meet user and K song is experienced and the demand 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 earphone, and this microphone earphone both can carry out Double-ear type sound-recording, By arranging reverberation effect unit, downmixing unit and monitoring playback unit etc. in microphone earphone and the wireless of applicable high quality audio can also be used Transmission means, effectively promote the K song of user experience and high-quality sound share ability.
Propose a kind of wireless K and sing microphone earphone, including being positioned at the left microphone of auricle position, right microphone, analog digital conversion when wearing this earphone Device ADC, reverberation effect unit, downmixing unit, D/A conversion unit, left speaker, right speaker, wireless connections unit, by left and right transaudient The human voice signal of device pickup enters reverberation effect unit after ADC carries out analog digital conversion, and digitized human voice signal is mixed by reverberation effect unit Sending it to downmixing unit after ringing effect process, wireless connections unit receives the music accompaniment signal sent by mobile terminal and sends it to audio mixing Unit, human voice signal is carried out with music accompaniment signal mixing and sending audio signal to DAC, is raised by left and right after digital-to-analogue conversion by downmixing unit Sound device output sound is to user.
Further, mixed for downmixing unit audio signal can wirelessly be returned to mobile terminal by wireless connections unit, or, wireless Connect unit and directly the human voice signal after ADC analog digital conversion is returned to mobile terminal, or, after earphone is worn on human ear, a utilization left side, Right microphone carries out the recording of ears holography sound field, and the holophonic field signal after ADC analog digital conversion is directly returned to mobile by wireless connections unit Terminal.
Further, earphone farther includes close-talking microphone, is positioned near mouth after wearing earphone, and can be near from this according to the regulation of following formula Say the ratio that the signal of microphone mixes with left and right microphone:
SL=L+aC, SR=R+aC
Wherein SL、SRBeing respectively the mixed signal of left and right microphone and the signal of close-talking microphone, L, R are the signal of left and right microphone, and C is near Saying the signal of microphone, a is proportionality coefficient.
Further, the mixed proportion of voice and musical background is adjusted by downmixing unit according to the demand of user；Mobile terminal is mobile phone, flat board Computer, laptop computer；Earphone is ear-shield type or PlayGear Stealth.
Further, the wireless connections between microphone earphone and mobile terminal include bluetooth connected mode, and wireless connections unit uses blue tooth RFCOMM Passage by single channel or multichannel audio signal, human voice signal or holophonic field signal uplink to mobile terminal, code encoding/decoding mode use SBC, One of OPUS, Apt-X, AAC.
Accompanying drawing explanation
Fig. 1 is the system block diagram of the wireless K song microphone earphone of the present invention
Fig. 2 is the external structure of the wireless K song microphone earphone of the present invention
Detailed description of the invention
In conjunction with accompanying drawing, the wireless K song microphone earphone of the present invention is described in detail.Accompanying drawing 1,2 shows that the wireless K of the present invention sings Mike Otopyorrhagia machine 1 and can carry out the mobile terminal 2 of wireless connections with it, wireless K song microphone earphone 1 includes being positioned at when wearing this earphone auricle position Left microphone 111, right microphone 112, AD conversion unit ADC12, reverberation effect unit 13, downmixing unit 14, D/A conversion unit DAC15, left speaker 161, right speaker 162, wireless connections unit 17, by human voice signal's warp of left and right microphone 111,112 pickup ADC12 enters reverberation effect unit 13, after reverberation effect unit 13 carries out reverberation effect process to digitized human voice signal after carrying out analog digital conversion Sending it to downmixing unit 14, wireless connections unit 17 receives the music accompaniment signal sent by mobile terminal 2 and sends it to downmixing unit 14, human voice signal is carried out with music accompaniment signal mixing and sends this audio signal to DAC15 by downmixing unit 1, after digital-to-analogue conversion by left, Right speaker 161,162 output 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 to mobile terminal 2 by wireless connections unit 17, and Can carry out recording and use a network for share by the built-in application of mobile terminal 2；Optionally, wireless connections unit 17 also can directly will pass through Human voice signal after ADC12 analog digital conversion returns to mobile terminal 2, mobile terminal 2 carry out the subsequent treatment such as audio mixing；Additionally, when earphone is worn After human ear, utilizing left and right microphone 111,112 also can carry out the recording of ears holography sound field, wireless connections unit 17 also can be directly by through ADC12 Holophonic field signal after analog digital conversion returns to mobile terminal 2, and is carried out record by mobile terminal 2.
As the improvement of a upper embodiment, earphone 1 farther includes close-talking microphone 113, is positioned near mouth after wearing earphone, its can as left, Supplementing further of right microphone 111,112 pickup, promotes voice representability, and can regulate from this close-talking microphone 113 according to formula (1) The ratio that mixes with left and right microphone 111,112 of signal:
