Background
Fig. 1 shows a hardware block diagram of a conventional bluetooth headset, which includes a BT IC (bluetooth chip) and a power-on key, a volume-up key, a volume-down key, and an Antenna, a Mic (microphone), an SPK (speaker), and an EEPROM (Electrically Erasable-Erasable Programmable Read-Only Memory) mounted on the bluetooth chip. The starting-up key comprises pairing and starting-up and shutdown functions; a volume adding key is used for realizing the volume increasing function; and reducing the volume to realize the volume reduction function.
The function definition of the keys is adaptive to the common Bluetooth headset. However, when the bluetooth headset is applied in some setting scenes, if the button is multiplexed and the button is provided with a setting mode selection corresponding to the setting scene, false triggering is easily caused, and thus, the existing bluetooth headset has a problem that the selection of the setting mode is difficult. For example, when the bluetooth headset is applied to a translation scene, there is a problem in that selection of a translation mode corresponding to the translation scene is difficult. A specific form of the translation scenario herein may be that a bluetooth headset sends a voice signal with the language information of a language to a mobile phone APP (third party application), and the APP translates the voice signal into a voice signal with the language information of B language, and then sends the voice signal to another bluetooth headset. Of course, the translation scenario referred to in this application may be other forms of translation scenarios.

the mode selection switch 31, one end of which is connected with a set power voltage, the other end of which is connected with the input end of the channel control switch 32, and is configured to output the received mode selection instruction to the channel control switch;
the control end of the access control switch 32 is connected to the mode selection control pin of the bluetooth chip, the output end of the access control switch is connected to the mode selection pin of the bluetooth chip, the access control switch is configured to receive the mode selection command input by the mode selection switch, and the internal connection between the input end of the access control switch and the output end of the access control switch is switched on or off under the action of the mode selection control command received by the control end of the access control switch.
Specifically, here, when the mode selection control command indicates that the mode selection is enabled, the input terminal of the path control switch and the output terminal of the path control switch are turned on, and at this time, the mode selection command received by the path control switch from the input terminal thereof is output to the bluetooth chip through the output terminal thereof; when the mode selection control command indicates that the mode selection is not enabled, the input end of the access control switch and the output end of the access control switch are disconnected, and at the moment, the mode selection command received by the access control switch from the input end of the access control switch cannot be output to the Bluetooth chip through the output end of the access control switch.
In order to prevent the mode selection circuit from being disabled from operating the mode selection switch to generate circuit jitter, preferably, the mode selection circuit further comprises: an anti-shake unit 33;
the input end of the anti-jitter unit 33 is connected to the input end of the mode selection switch, and the output end thereof is grounded.
In order to prevent the circuit from receiving static electricity generated by internal electronic devices, and the mode selection circuit can not work normally, preferably, the mode selection circuit further comprises: a static electricity suppressor 34;

In order to satisfy the simplicity and practicability of the mode selection circuit, the anti-jitter unit 33 preferably includes a capacitor.
Preferably, the static electricity suppressor 34 is an anti-static diode.
Optionally, the mode selection switch 31 is a key trigger switch.
Optionally, the mode selection switch 31 is a touch switch.
A specific circuit structure of the mode selection circuit provided in the embodiment of the present application can be shown in fig. 4, and in fig. 4, the mode selection switch is taken as a key trigger switch and one end of the mode selection switch is grounded for example. The BT IC is a bluetooth chip, SW is a switch shorthand, SW2 is a Mode selection switch/button, APP _ Mode indicates that the command output by SW2 is a Mode selection command, C107 is an anti-jitter capacitor, D1 is an anti-static diode, U14 is a path control switch, and a resistor R is used for adjusting the voltage input to the Mode selection switch to perform voltage division. When the signal level of the input Pin1(GPIO _ CON) becomes high, Pin4 is internally connected to Pin 5; when the signal level of input Pin1 goes low, Pin4 is internally disconnected from Pin 5.
The specific mode selection process may be as follows:
firstly, after the earphone and the mobile phone are paired, a user opens the mobile phone APP, the mobile phone APP sends a mode selection enabling instruction to the Bluetooth chip at the moment, the Bluetooth chip outputs an enabling signal through a GPIO _ CON interface, and the U14 is in a working state, so that the pin4 and the pin5 of the U14 are communicated;
Next, the user presses the SW2 key. At this time, Pin4 of U14 is pulled low, which can be detected by Mod _ sel Pin of BT IC since Pin4 and Pin5 of U14 are turned on; after receiving the pull-down signal, the BT IC sends a wireless transmission mode selection command to the APP; after receiving the command, the APP starts to enter a translation mode;
when the user uses the translation mode completely and exits the translation APP, the APP simultaneously sends a mode selection non-enabling instruction to the Bluetooth headset (through wireless Bluetooth), and the GPIO _ CON of the BT IC outputs a disable signal to the U14; pin4 and pin5 of U14 are thus disconnected; even if the SW2 is triggered by mistake, the wrong judgment of the BT _ IC can not be caused, thereby causing the mode switching error.
Of course, fig. 4 is a schematic diagram showing one possible specific circuit form, and the specific process of mode selection described above is merely exemplary. Fig. 4 is an example in which the mode selection pin of the bluetooth chip is specifically enabled by a high-level signal, and the mode is switched by pressing a low-level signal. In practical use, specifically, the mode selection pin of the bluetooth chip is enabled by a low-level signal, the mode selection pin of the bluetooth chip is enabled by a high-level signal, and the mode switching is performed by pressing a low-level signal with a key or the mode switching is performed by pressing a high-level signal with a key, which may be manually set based on a specific circuit, and is not limited herein.
When the mode selection switch selects the setting mode by a high-level signal, SW2 may be switched with the position of the resistor R. At this time, the logic switching is changed, namely, the key presses a high level to switch the modes; the default state is the 0 level.
