Dynamic terminal, K is as follows the step of song microphone is respectively provided with bluetooth connection unit, karaoke method with mobile terminal：By bluetooth K song microphone with
Mobile terminal carries out Bluetooth pairing using bluetooth connection unit, after successful matching, it is established that two equipment are bi-directionally connected, bluetooth K
Song microphone pickup human voice signal, to the human voice signal audio effect processing is carried out, it is of course also possible to without audio effect processing, it is mobile whole
End Jing downlinks send music accompaniment signal and sing microphone to bluetooth K, and microphone is sung by Jing audio effect processings or without audio effect processing by K
Human voice signal mixed with music accompaniment signal and reset to user, realize that true K sings the simulation of scene with this；Wherein, K
Method of attachment between song microphone and mobile terminal is specifically included：First, the bluetooth connection unit sung by K in microphone provides SDP clothes
Business, in SDP services service describing is added, and core is to which depict UUID and RFCOMM passages；Secondly, talked about using K songs
Bluetooth connection unit in cylinder is matched with the bluetooth connection unit of mobile terminal；After successful matching, by the bluetooth of both sides
Connection unit is set up the SOCKET based on RFCOMM passages and is connected；After connection establishment, the bluetooth connection unit for singing microphone by K leads to
Crossing RFCOMM passages carries out the transmission of voice data.
Wherein, for ANDROID or PC systems, described UUID and RFCOMM Path Setups are based only upon and play K
Pair relationhip between song microphone and mobile terminal；And based on the SOCKET connections set up, the bluetooth connection unit of microphone is sung by K
The transmission of voice data is directly carried out by RFCOMM passages.
Wherein, for IOS systems, the bluetooth connection unit for singing microphone in K inherently has HFP/HSP and A2DP
Pairing is set up on the basis of service；Further, a verification process is needed, that is, is being set up based on RFCOMM passages
On SOCKET connections, after being authenticated by IAP1/2 agreements, EAP protocol is recycled to carry out the transmission of voice data.
Further, the code encoding/decoding mode of Bluetooth audio frequency is encoded using Whole frequency band, including SBC, OPUS, Apt-X, AAC are compiled
Code.
Further, mobile terminal both can send musical background and sing microphone to K using A2DP passages, it is also possible to use
RFCOMM passages send musical background.
Further, mobile terminal is returned to including by mixed audio signal, and by the built-in application of mobile terminal
Recorded and used a network for the step of sharing.
Further, including directly by K sing microphone process or untreated human voice signal return to mobile terminal
The step of.
Further, the effect mixed proportion of voice and musical background being adjusted including the demand according to user.
Wherein, mobile terminal includes mobile phone, panel computer, laptop computer.
Specific embodiment
Bluetooth K song microphone is provided and the mobile terminal of bluetooth connection can be carried out with it, K song microphones are respectively provided with mobile terminal
Bluetooth connection unit, K song steps are as follows：Bluetooth K song microphone is carried out into Bluetooth pairing with mobile terminal using bluetooth connection unit,
After successful matching, it is established that two equipment are bi-directionally connected, bluetooth K song microphone pickup human voice signal to the human voice signal carries out sound
Effect process, it is of course also possible to without audio effect processing, mobile terminal Jing downlinks send music accompaniment signal and sing to bluetooth K
Microphone, sing microphone by K carries out mixing laying equal stress on by Jing audio effect processings or human voice signal without audio effect processing with music accompaniment signal
Put to user, realize that true K sings the simulation of scene with this.
The method of attachment that K is sung between microphone and mobile terminal is specifically included：First, the bluetooth connection unit in microphone is sung by K
SDP services are provided, in SDP services service describing is added, core is to which depict UUID and RFCOMM passages；Secondly,
Sing the bluetooth connection unit in microphone using K to be matched with the bluetooth connection unit of mobile terminal, wherein for ANDROID or
