Description of the drawings
Fig. 1 is the circuit structure connection diagram of the utility model Bluetooth audio device.
Fig. 2 is the partial layout schematic diagram of the pcb board of the utility model Bluetooth control device.
Specific implementation mode
As a kind of embodiment of the utility model, as shown in Figure 1, 2, which includes main controller 50 and indigo plant
Tooth anti static device 10, the bluetooth anti static device 10 include pcb board 20 and the bluetooth controller being set on the pcb board 20
30, the bluetooth controller 30 includes Bluetooth data transfer port, power port VIN and reseting port TP6, the power end
Mouth VIN is connect with external power supply 40, and the Bluetooth data transfer port is used for transmission blue-teeth data letter that is to be sent or receiving
Breath, the reseting port TP6 is hanging, and the position of the close reseting port TP6 is white space 31 on the pcb board 20；Institute
Main controller 50 is stated to connect by Bluetooth data transfer port communication with the bluetooth anti static device 10.
In the present embodiment, bluetooth controller 30 is powered by power port VIN external power supplys 40, and reseting port TP6 is
The internal reset foot of bluetooth controller 30 then needs when needing to 30 programming program of bluetooth controller by the reset terminal
Mouth TP6 is set to high level.After the complete program of programming, when bluetooth controller 30 works normally, then reseting port TP6 is hanged
Sky is not connected to any component.Main controller 50 is connected with bluetooth controller 30 by Bluetooth data transfer port communication, bluetooth control
The instruction for the main controller 50 that device 30 processed comes according to Bluetooth data transfer port transmission carries out bluetooth perfect match, includes mainly
Match the information such as object and pairing time.Meanwhile bluetooth controller 30 is then by the Bluetooth audio frequency data transmission received to master control
Device 50 carries out digital-to-analogue decoding and becomes analog audio signal.
When bluetooth controller 30 encounters electrostatic pulse interference, by the white space 31 near reseting port TP6, then may be used
Electrostatic pulse interference and insulation is come, then the reseting port TP6 of the bluetooth controller 30 will not receive the reset signal of mistake, no
Internal reset can be arbitrarily carried out, the antistatic interference performance and stability of bluetooth controller 30 is improved, extends service life.
