Specific implementation mode
The specific implementation mode of the application is described in more detail below in conjunction with the accompanying drawings.
The two-channel bluetooth headset single sound channel bluetooth headset and audio accessories that the application proposes, wherein monophonic bluetooth ear
Machine is as shown in Figure 1, include Bluetooth chip U1, the first loud speaker SPK1, mode switch S1 and output audio interface J1, Bluetooth chip
U1 includes the first audio output pin SPK1L/ SPK1R, the second audio output pin SPK2L/ SPK2R and data input and output
Pin D+/D-；First audio output pin SPK1L/ SPK1R the first loud speakers of connection SPK1.
First input end I1L/I1R connection the second audio output pin SPK2L/SPK2R of mode switch S1, mode switch
The second input terminal I2D+/I2D- connection data input and output pins D+/D- of S1；The output end O31/O32 of mode switch S1 connects
Meet output audio interface J1；Mode switch S1 connects for switching its first input end I1L/I1R or the second input terminal I2D+/I2D-
Logical output end O31/O32, to realize the switching of audio output mode or data-transmission mode.
As shown in Fig. 2, audio accessories include that can realize the input audio interface J2 and defeated of connection with output audio interface J1
The the second loud speaker SPK2 for entering the tone frequency channel wire L of audio interface J2 connections and being connect with tone frequency channel wire L.It will input audio interface J2
After accessing the output audio interface J1 of bluetooth headset, it is two-channel bluetooth headset that single sound channel bluetooth headset, which can be applied,.
The application specific implementation mode that definition mode does not switch, can be the mechanical switch of user's operation, can also
It is electronic switch.
Specifically, by taking the mechanical switch of user's manual switching as an example, when needing to realize two-channel bluetooth headset in application,
When bluetooth headset being needed to realize audio output mode, user stirs mode switch S1 and carries out pattern switching, and as shown in Fig. 2,
The input audio interface J2 of external audio accessories is accessed to the output audio interface J1 of bluetooth headset, then the of Bluetooth chip U1
Two audio output SPK2L/SPK2R are played back through tone frequency channel wire L+/L- from the second loud speaker SPK2, in conjunction with bluetooth headset itself
First audio output SPK1L/SPK1R of the Bluetooth chip that the first loud speaker SPK1 is played out is realized double with mono headset
The application of sound channel earphone.When need bluetooth headset realize data-transmission mode when, for example, charging bluetooth earphone, bluetooth headset with
PC connections carry out updating operation etc., and user stirs mode switch S1 and carries out pattern switching so that the input of Bluetooth chip U1 is defeated
Go out data D+/D- and realizes data transmission, such as PC, charger etc. with external equipment by exporting audio interface J1.
The application is realized on the basis of single sound channel bluetooth headset by increasing mode switch and audio accessories as a result,
The application of two-channel bluetooth headset does not influence the transmission of other data of the bluetooth headset in addition to audio data, improves user
Usage experience.
If mode switch S1 switchs for electronic pattern, in the embodiment of the present application, mode switch S1 further includes enabled pin
EN；As shown in figure 3, a control output pin CTRL of enabled pin EN connection Bluetooth chips, by Bluetooth chip U1 to bluetooth
The application model of earphone switches over, such as Bluetooth chip U1 controls output pin CTRL acquiescences at it and exports low level so that
Mode switch S1 is based on the low level cut-flower audio frequency output channel, can realize two-channel bluetooth headset application, and works as bluetooth core
When piece U1 detects that data transmission interface is inserted into, controls output pin CTRL from it and export a high level, then mode switch S1
Data transmission channel is switched to based on the high level.
In the embodiment of the present application, data transmission interface can be multiplexed with output audio interface J1, and the case where being multiplexed
Under, Bluetooth chip U1 can control output pin CTRL from it in the case where playing music and export low level enable signal, make
It obtains mode switch S1 and is switched to audio frequency output channel, and in the case where not playing music or detect that output audio interface J1 is inserted
After entering external interface, then controls output pin CTRL from it and export high level enable signal so that mode switch S1 is switched to number
According to transmission channel.
Certainly, in the application of electronic pattern switch, the application does not limit using Bluetooth chip U1 or other control chips
Enable signal is sent out, as shown in figure 4, difference can also be realized by increasing mode selector switch S2 connections enabled pin EN
Enable signal, mode selector switch S2 is stirred to provide different enabled letters to mode switch S1 according to service condition by user
Number.
The concrete application form for not limiting output audio interface in the embodiment of the present application can be and single sound channel bluetooth headset
Independent two interfaces of the data transmission interface such as serial ports, USD interfaces of itself, can also be existing with single sound channel bluetooth headset
Data transmission interface multiplexing；When exporting the USB female seat interface of audio interface multiplexing single sound channel bluetooth headset, in audio accessories
Input audio interface be USB male seat interfaces.
As shown in figure 5, for exporting the existing USB interface multiplexing of audio interface and bluetooth headset, audio interface is exported
J1 is USB female seat, the output end O31/O32 of the data pin COM+ and COM- connection mode switch S1 of the USB female seat；As schemed
Show, when mode switch S2 pushes top, can be used for usb data communication, when mode switch S2 toggles it to lower section, Ke Yiyong
It is exported in the second audio signal.
Use for the convenience of the user is configured with the magnet that can adsorb the second loud speaker SPK2 in input audio interface J2, when
When need not apply two-channel bluetooth headset, audio accessories can be wrapped on the positions such as wrist, be based on the magnet by second
Loud speaker SPK2 is adsorbed on input audio interface J2, it is not easy to be lost, be also allowed for carrying.
The bluetooth headset and two-channel bluetooth headset that above-mentioned the application proposes, on the basis of existing single sound channel bluetooth headset
On, increase mode switch and audio accessories, the application of two-channel bluetooth headset may be implemented, while nor affecting on bluetooth headset
Data transmission improves the usage experience of user.
It should be noted that the above description is not intended to limit the present invention, the utility model is also not limited to
The example above, variation that those skilled in the art are made in the essential scope of the utility model retrofit, add
Add or replace, should also belong to the protection scope of the utility model.
