Problems solved by technology

Traditionally, there are two solutions for establishing communication. One is to add a Bluetooth module that communicates with the mobile terminal in the charging compartment. The system design will be very complicated if it needs to communicate with the Bluetooth module of the charging compartment and also with the Bluetooth module of the Bluetooth headset.
The other is to realize the communication between the charging case and the Bluetooth headset through the carrier on the power line, but the carrier loading and demodulation increase the complexity of the system and affect the charging of the Bluetooth headset at the same time.

Embodiment 1

[0035] like figure 2 As shown, a Bluetooth headset supporting communication with a charging compartment includes: a charging compartment 1 and a Bluetooth headset 2, the charging compartment 1 is provided with electrode contacts, and the Bluetooth headset 2 is provided with an electrode interface for connecting with the electrode contacts. The charging bin 1 includes a first control unit 3, a battery in the charging bin 1, and a power supply module 5. The first control unit 3 is connected to the power supply module 5 for signals. The battery in the charging bin 1 is connected to the electrode contacts through the power supply module 5, and the electrode contacts It is also electrically connected with the first control unit 3 . The electrode contacts include V+ contacts and V- contacts.

[0036]The Bluetooth earphone 2 includes a second control unit 6, an earphone battery 7, a charging module 8 and a load 9, the earphone battery 7 is electrically connected to the second contr...

Embodiment 2

[0047] like image 3 and Figure 4 As shown, the difference between the bluetooth earphone supporting communication with the charging compartment described in this embodiment and the first embodiment is that the bluetooth earphone 2 also includes a rectifier module 10, and the second control unit 6 is electrically connected to the electrode interface; the load 9 The input terminal side of the rectification module 10 is connected to the electrode interface, or the load 9 is provided at the output terminal side of the rectification module 10 .

[0048] Wherein, in order to improve power supply efficiency, the rectification module 10 mainly uses full-wave rectification, and half-wave rectification is also acceptable. The rectification module 10 can be implemented with traditional diodes, or with transistors, preferably transistors, because it facilitates integration in integrated circuits.

[0049] The positive pressure branch and the negative pressure branch are used to establ...

Abstract

The invention discloses a Bluetooth earphone supporting communication with a charging bin and a communication mode. The Bluetooth earphone comprises the charging bin and the Bluetooth earphone, the charging bin is provided with an electrode contact, the Bluetooth earphone is provided with an electrode interface connected with the electrode contact, and the charging bin comprises a first control unit, a charging bin battery and a power supply module. The first control unit is in signal connection with the power supply module, the charging bin battery is connected with the electrode contact through the power supply module, and the electrode contact is further electrically connected with the first control unit. The Bluetooth earphone comprises a second control unit, an earphone battery, a charging module and a load, and the earphone battery is electrically connected with the second control unit and the charging module. The communication mode is realized by using the Bluetooth earphone. Data communication between the charging bin and the Bluetooth earphone is established, and data communication between the charging bin and a mobile phone is established through an original Bluetooth module in the Bluetooth earphone.

Description

technical field [0001] The invention belongs to the field of TWS bluetooth earphones, in particular to a bluetooth earphone supporting communication with a charging compartment and a communication method. Background technique [0002] With the promotion of wireless earphones, most of the current smart earphones adopt the TWS-true stereo wireless binaural bluetooth earphone solution. The communication method of the traditional TWS Bluetooth headset is as follows, such as figure 1 As shown, the charging box passes figure 1 The contact shown by the dotted line in the middle, V+ and V- two points to charge two Bluetooth headsets, this contact is only for charging, no data communication. When two Bluetooth earphones are to be taken out of the charging box, the Bluetooth earphones know that they need to establish a Bluetooth relationship with mobile terminals such as mobile phones and tablets after judging that the voltage at V+ / V- is powered off. The data information, such as ...
