Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a TWS headset presence detection method according to a first embodiment of the present invention includes steps S101 to S103:
s101, a charging box sends a starting signal to a TWS earphone and stops charging the TWS earphone;
referring to fig. 2 and 3, the charging box 10 is a device for placing and charging a TWS headset, which specifically includes a left headset 20 and a right headset 30. One of the left earphone 20 and the right earphone 30 is a master earphone, and the other is a slave earphone, and the master earphone performs bluetooth communication with the slave earphone and a user terminal (e.g., a mobile phone), respectively.
The charging box 10 has therein a logic control device 11, such as a control chip. In addition, the charging box 10 further has a left earphone detecting point 12(Vbus _ L), a right earphone detecting point 13(Vbus _ R) and a battery 14, the logic control device 11 is electrically connected to the battery 14, the left earphone detecting point 12 and the right earphone detecting point 13, respectively, the left earphone detecting point 12 on the charging box 10 is used for being electrically connected to a detecting point 21(Vbus _ L) on the left earphone 20, and the right earphone detecting point 13(Vbus _ L) on the charging box 10 is used for being electrically connected to a detecting point 31(Vbus _ L) on the right earphone 30.
Specifically, the left earphone 20 includes a left bluetooth chip 22, a battery 23, a speaker 24, and a microphone 25, wherein the battery 23, the speaker 24, the microphone 25, and the left detection point 21 are respectively connected to the left bluetooth chip 22; correspondingly, the right earphone 30 includes a right bluetooth chip 32, a battery 33, a speaker 34, and a microphone 35, wherein the battery 33, the speaker 34, the microphone 35, and the right detection point 31 are respectively connected to the right bluetooth chip 32. Since the bluetooth chip, the battery, the speaker and the microphone are all conventional devices, they are not described herein.
In specific implementation, in order to trigger the method of this embodiment, the charging box has a hall switch 15 for detecting whether the charging box is opened, the hall switch 15 is electrically connected to the logic control device 11, the hall switch 15 is detected by the logic control device 11 that a level change occurs, and the logic control device 11 determines that the charging box 10 is opened.
When the charging box 10 judges that the charging box 10 is opened through the hall switch 15, the charging box 10 sends a power-on signal to the TWS headset, and reduces the voltage value of the detection points (including the left headset detection point 12 and the right headset detection point 13) on the charging box 10 from the charging voltage value to a preset charging stop voltage value, so as to stop charging the TWS headset. The charging voltage value is, for example, 5V, the charging stop voltage value is, for example, 1.2V, and the voltage corresponding to the charging stop voltage value is for maintaining simple signal transmission.
Since the TWS headset includes the left earphone 20 and the right earphone 30, the specific charging box 10 transmits a power-on signal to the left earphone 20 and the right earphone 30, respectively, and stops charging the left earphone 20 and the right earphone 30.
S102, the TWS earphone is started up when receiving the starting-up signal, and the Vbus voltage value of the TWS earphone is periodically collected in the starting-up state;
when receiving the power-on signal, the left earphone 20 and the right earphone 30 are respectively powered on, and are switched from a power-off state to a power-on state, and the left earphone 20 and the right earphone 30 respectively periodically collect Vbus voltage values in the power-on state, for example, once every 1 minute. Namely, the left earphone 20 obtains the voltage value of the left detection point 21 through the left bluetooth chip 22, and the right earphone 30 obtains the voltage value of the right detection point 31 through the right bluetooth chip 32.

The left earphone 20 compares the acquired Vbus voltage value with a preset charging stop voltage value (for example, 1.2V), specifically, the left bluetooth chip 22 compares the acquired Vbus voltage value with a preset charging stop voltage value, when the Vbus voltage value acquired by the left earphone 20 is greater than or equal to the charging stop voltage value, it is determined that the left earphone 20 is in the charging box 10, specifically, the left bluetooth chip 22 determines that the right earphone 30 is in the charging box 10, otherwise (that is, when the Vbus voltage value acquired by the left earphone 20 is less than the charging stop voltage value), it is determined that the left earphone 20 is not in the charging box 10, and active identification of whether the TWS earphone is in place is achieved. The result of determining whether the bluetooth device is in place may be sent via the left bluetooth chip 22, for example, to the user terminal.
Correspondingly, the right earphone 30 compares the acquired Vbus voltage value with a preset charging stop voltage value (for example, 1.2V), specifically, the acquired Vbus voltage value is compared with the preset charging stop voltage value by the right bluetooth chip 32, when the Vbus voltage value acquired by the right earphone 30 is greater than or equal to the charging stop voltage value, it is determined that the right earphone 30 is in the charging box 10, specifically, the right bluetooth chip 32 determines that the right earphone 30 is in the charging box 10, otherwise (that is, when the Vbus voltage value acquired by the right earphone 30 is less than the charging stop voltage value), it is determined that the right earphone 30 is not in the charging box 10, and a result of determining whether the right earphone 30 is in place can be sent out through the right bluetooth chip 32, for example, to a user terminal.

In addition, as a specific example, the method of this embodiment further includes:
the left earphone 20 and the right earphone 30 are actively connected with each other after being powered on, if a user terminal (such as a mobile phone) has a last pairing record, the mobile phone of the user can also be actively connected, and after all the connections are completed, the left earphone 20 and the right earphone 30 repeat the action of periodically acquiring the Vbus voltage value so as to periodically detect whether the left earphone 20 and the right earphone 30 are in the charging box, so that preparation is made for some functions of identifying whether the TWS earphone is in the charging box.
