During the first audio frequency data interface A the first digital audio and video signals, or the second audio processing chip 20 is received from the second wheat
During the second audio signal that gram wind 24 is gathered, noise reduction branch road 25 is carried out to the first digital audio and video signals and the second audio signal respectively
Noise reduction process, improves the Transfer Quality of audio signal.The circuit framework and drop of noise reduction branch road 25 employed in noise reduction microphone
Algorithm of making an uproar is common circuit framework used in the prior art and noise reduction algorithm, and is not that this practicality is new with diversified forms
The key protection point of type, will not be repeated here.
In the one end of the second headset body 2, the second audio processing chip 20 connection headset plug 26, therefore the second earphone may be used also
To pass through headset plug 26 and earphone cord and audio-frequence player device formation wired connection.
First headset body 1 and the second headset body 2 are provided with battery component in itself, specifically, in the first earphone
The first battery BATT1 is provided with body 1, the second battery BATT2 is provided with the second headset body 2.At the second audio
Charging module 27 is integrated with reason chip 20.Charging module 27 is preferably USB charging modules 27, the battery of charging module 27 and second
BATT2 connections.USB interface 28 is provided with USB charging modules 27, is connected by USB interface 28 and power-supply device, realization pair
Second battery BATT2 charging.When the first headset body 1 and the second headset body 2 are connected, the battery of charging module 27 and first
Circuit communication between BATT1, forms electrical connection, realizes by 28 pair of first battery BATT1 charging of USB interface.
Combined earphone provided by the utility model, can cause the first headset body and the second ear by circuit design
Machine body is used in combination, is reached the effect that single sound channel bluetooth headset and stereophone collaboration are used, is on the one hand carried
The audio signal quality of high bluetooth earphone, on the other hand causes stereophone to have the function of Bluetooth signal transmission, after fractionation,
It can use that there is provided the multiple usage experience of user as monomer-type single sound channel bluetooth headset and stereophone again.This practicality is new
Type has the advantages that circuit structure is reasonable and using effect is good.
