Specific implementation mode
The utility model is further described with the following Examples.
A kind of double compatible bluetooth earphones of the present embodiment, include the USB interface and Bluetooth chip of TYPE-c-type, TYPE-C
The USB interface of type includes USB-TYPE-C chips, and USB-TYPE-C chips of bluetooth headset connect according to the USB of its TYPE--C type
Whether mouth is connect with the audio frequency apparatus for the USB interface for having TYPE-c-type by data line, and different electricity is sent to Bluetooth chip
Ordinary mail number, Bluetooth chip control being turned on or off for its own according to the level signal.
Wherein, the USB interface of TYPE-c-type of bluetooth headset and the audio frequency apparatus for the USB interface for having TYPE-c-type are logical
Data line connection is crossed, then the USB interface of TYPE-c-type of bluetooth headset receives high level signal, and by the high level signal
It send to Bluetooth chip, Bluetooth chip is closed, and otherwise Bluetooth chip is opened.
Specifically, as shown in Fig. 2, the USB interface of TYPE-c-type of bluetooth headset includes chip U1, the CC1 of chip U1
Pin or CC2 pins receive the level signal that the USB interface of TYPE-c-type from audio frequency apparatus is sent out, chip U1's
The level signal is issued Bluetooth chip by CC1 pins or CC2 pins, and Bluetooth chip receives the level signal by PIO22 pins.
Wherein, the USB interface of TYPE-c-type of bluetooth headset and the audio frequency apparatus for the USB interface for having TYPE-c-type are logical
When crossing data line connection, the CC1 pins or CC2 pins of chip U1 receive the USB interface of TYPE-c-type from audio frequency apparatus
