Brief description of the drawings
Fig. 1 is the structural representation of the musical instrument deduction microphone system of the present invention
Embodiment
With reference to accompanying drawing, the musical instrument deduction microphone system of the present invention is described in detail.As shown in Figure 1, it is of the invention Musical instrument deduction microphone system include Bluetooth audio frequency module 1, Bluetooth terminal 2 (2 '), signal source module 3, signal source module 3 will Musical instrument or human voice signal are sent to Bluetooth audio frequency module 1 by wired or wireless link, and Bluetooth audio frequency module 1 is by the pleasure received Sent to Bluetooth terminal 2 (2 '), carried out by Bluetooth terminal 2 (2 ') follow-up in the way of Bluetooth audio frequency after device or human voice signal's processing Processing, the subsequent treatment to musical instrument or human voice signal including being recorded, being shared by mobile network, live, public address.
Bluetooth audio frequency module 1 includes audio interface unit 11 and Bluetooth audio frequency transmitting element 12, and audio interface unit 11 is used In receiving musical instrument or human voice signal from signal source module 3, signal source module 3 may include that a variety of transducers or audio I/O are set It is standby, such as:Microphone 31, PZT (piezoelectric transducer) 32, I2S interface equipments 33 (such as digital music instruments), audio electrical signal interface equipment 34 are (such as Sound console), wireless Bluetooth interface equipment 35 (such as Bluetooth microphone), audio interface unit 11, which has, is adapted to above-mentioned a variety of transducings The corresponding interface of device or audio I/O equipment, certainly, the interface of every kind of signal source may include more than one passage;COBBAIF Unit 11 will receive one or more transducers from signal source module 3 or one or more letter of audio I/O equipment Sent after number conversion to Bluetooth audio frequency transmitting element 12, Bluetooth audio frequency transmitting element 12 will be sent after one or more Signal coding To the Bluetooth terminal 2 (2 ') with its wireless connection.
Wherein it is possible to a kind of signal source is only accessed to the audio interface unit 11 of Bluetooth audio frequency module 1, for example only will be transaudient Device 31 accesses to transmit voice or musical instrument sound, can also access multiple signal source, such as simultaneously by microphone 31 and piezoelectric energy-conversion Device 32 is accessed, and microphone 31 is used to pick up voice, and PZT (piezoelectric transducer) is then fixed on pickup musical instrument sound on the plucked instruments such as guitar, Microphone 31 can be used to pick up the acoustical signal of musical instrument air transmitted, while picking up musical instrument surface vibration using PZT (piezoelectric transducer) Both signals, can be respectively allocated in left and right sound channels to obtain the auditory perception of more spatial impression by vibration signal;When So, multiple signal source can also independent assortment as needed, using the channel transmission characteristic of Bluetooth audio frequency module 1, can make Bluetooth terminal 2 (2 ') is convenient to carry out subsequent treatment to multi-path signal.Bluetooth terminal 2 can be Bluetooth mobile terminal, including The application journey of adaptation Bluetooth audio frequency module 1 is installed on mobile phone, tablet personal computer, PDA, laptop computer etc., Bluetooth terminal 2 The Bluetooth audio signals that Bluetooth terminal 2 is received can be recorded, edited, the processing such as network sharing by sequence, can also pass through application Program sends a control signal to Bluetooth audio frequency module 1 and it is configured;Bluetooth terminal 2 ' can be bluetooth public-address system, including Baffle Box of Bluetooth, bluetooth earphone etc., Bluetooth terminal 2 ' can also be provided with the application program of adaptation Bluetooth audio frequency module 1, for configuring And reset the Bluetooth audio signals received.
Wherein, the bluetooth connection mode between Bluetooth audio frequency module 1 and Bluetooth terminal 2 (2 ') is as follows:First, by Bluetooth audio frequency Bluetooth audio frequency transmitting element 12 in module 1 provides SDP services, and service describing is added in SDP services, and core is that it is described UUID and RFCOMM passages;Secondly, the Bluetooth audio frequency transmitting element 12 in Bluetooth audio frequency module 1 and Bluetooth terminal 2 are utilized Bluetooth connection unit in (2 ') is matched, wherein for ANDROID or PC systems, can be based only upon described UUID and RFCOMM Path Setups play the pair relationhip between Bluetooth audio frequency module 1 and Bluetooth terminal 2 (2 '), for IOS systems For, then it is that inherently there is the base that HFP/HSP and A2DP are serviced in the Bluetooth audio frequency transmitting element 12 of Bluetooth audio frequency module 1 Pairing is set up on plinth;After successful matching, pass through Bluetooth audio frequency transmitting element 12 and the Bluetooth terminal 2 of Bluetooth audio frequency module 1 The bluetooth connection unit of (2 ') sets up the SOCKET connections based on RFCOMM passages;After connection is set up, for ANDROID or PC For system, then it can be passed through based on the SOCKET connections set up by the Bluetooth audio frequency transmitting element 12 of Bluetooth audio frequency module 1 RFCOMM passages directly carry out the transmission of voice data, for IOS systems, then also need to a verification process, that is, are being built On the vertical connections of the SOCKET based on RFCOMM passages, after being authenticated by IAP1/2 agreements, EAP protocol is recycled to carry out The transmission of voice data.Wherein, the code encoding/decoding mode for the Bluetooth audio frequency of the present invention is encoded using Whole frequency band, Whole frequency band coding Mode includes but is not limited to SBC, OPUS, Apt-X, AAC coding.
In addition, when the two or more signal source of signal source module 3 or multiple passages of same signal source access bluetooth , can also be by the built-in application program of Bluetooth terminal 2 (2 ') or directly in 1 pair of Bluetooth audio frequency module during audio-frequency module 1 State multiple path signals and carry out configuration adjustment, to obtain the sound effect of uniqueness, by taking two passages as an example, if inputting into bluetooth sound The input signal of the passage one of frequency module 1 is S1, the input signal of passage two is S2, the two paths of signals after corresponding configuration adjustment Respectively X1、X2, then have following formula:
X1=S1g4+S2g2……………………(1)
X2=S1g1+S2g3……………………(2)
Wherein, g1~g4For weight coefficient.Further can be by X1、X2Distribution realizes unique solid into left and right sound channels Sound effective value.
Using technical scheme, Bluetooth terminal can be used convenient and high-quality band performance is recorded And share, meet variation, the demand of modernization.
