Embodiment 1

[0022] Such as figure 2 As shown, it is a connection schematic diagram of a data card charging a Bluetooth headset according to an embodiment of the present invention. The notebook computer 10 obtains electricity through its power cord 1011; the data card 20 obtains the charging power supply voltage through the interface with the notebook computer 10, and after the charging power supply voltage is processed, the Bluetooth headset 30 is charged through the USB interface 2011 of the data card 20.

[0023] Such as image 3 Shown is a Bluetooth headset charging device according to an embodiment of the present invention. The device 300 includes a charging power supply voltage acquisition unit 301 for obtaining a charging power supply voltage from an interface between a data card and a computer; a power management unit 302 for converting the The charging power supply voltage is processed to become the charging voltage of the Bluetooth headset; the Bluetooth voltage output unit 303...

Embodiment 2

[0033] A data card for charging a bluetooth headset is provided, and a power management circuit for charging the bluetooth headset is included in its power management unit. The power management circuit is used to connect with the charging interface of the Bluetooth headset through a universal serial bus interface.

[0034] First of all, when designing the data card, we need to consider the circuit design requirements of the Bluetooth headset at the same time, and integrate the two circuit designs. The two parties share the power management circuit to achieve the purpose of increasing the capacity of the Bluetooth battery and charging it safely.

[0035] In the circuit design, the original charger is integrated on the data card to the charging circuit interface of the Bluetooth module, and the charging design of the USB interface is designed at the same time, so that the user can complete the charging of the Bluetooth headset during the process of surfing the Internet.

Abstract

The invention provides a method and a device for charging bluetooth earphones. The method comprises the following steps of: acquiring the voltage of a charge power supply from interface of the data card and a computer; converting the voltage of the charge power supply into the change voltage of the bluetooth earphones through processing; and outputting the voltage for charging the bluetooth earphones. The invention also provides the device for charging the bluetooth earphones and the data card. The technical proposal has the advantage that: the technique of acquiring the voltage of the charge power supply from the interface of the data card and the computer solves the problems of lack of in-time charge of bluetooth earphones and inconvenient carrying of a bluetooth earphone charger, and consequently facilitates the charging of the bluetooth earphones and avoids carrying a special charger.

Description

technical field [0001] The invention relates to a bluetooth earphone, in particular to a charging method and device for a bluetooth earphone. Background technique [0002] Whether it is a global mobile communication (GSM) network or a code division multiple access (CDMA) network, the previous wireless network mainly focused on voice services. With the broadbandization of wireless networks, more and more users access the Internet through wireless. Mobile phones can be connected to laptops or desktops to access the Internet, and at the same time, devices dedicated to Internet access: data cards have emerged. Such as figure 1 Shown is a structural block diagram of a data card in the prior art. The data card 100 device has various interface forms, including a personal computer memory card international association (PCMCIA) interface 101, a universal serial bus (USB) interface 102, a high-speed (Express) interface 103, and a 1394 interface 104. In this article, it is generall...
