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
