Embodiment 1

[0029] figure 1 It is a schematic structural diagram of the Bluetooth headset charging box provided in Embodiment 1 of the present application. like figure 1 As shown, the Bluetooth headset charging box includes:

[0030] The first contact end (TP end) and the second contact end (GND end); the second contact end is a ground end; the first contact end and the second contact end are used for docking with the two contact ends of the Bluetooth headset, thereby Realize the communication with the Bluetooth headset and charge the Bluetooth headset. Wherein, the communication with the Bluetooth headset can be used to detect whether there is an access device and determine whether the access device is a Bluetooth headset.

[0031] The first contact terminal is connected to the common terminal (COM, ie, the fourth pin of U1) of the first control chip (U1);

[0032] The control terminal (IN, ie, the sixth pin of U1) of the first control chip is connected to the enable terminal (GIPO_E...

Embodiment 2

[0040] The bluetooth headset provided in this embodiment can cooperate with the charging box for the bluetooth headset provided in the above-mentioned embodiment to achieve the effect of reducing the number of contact terminals between the bluetooth headset and the charging box. figure 2 It is a schematic structural diagram of the bluetooth earphone provided by the second embodiment of the present application. like figure 2 As shown, the Bluetooth headset includes:

[0041] The third contact terminal (TP terminal) and the fourth contact terminal (GND terminal); the fourth contact terminal is a ground terminal;

[0042] The third contact terminal is connected to the control terminal (IN, ie the 6th pin of U2) and the common terminal (COM, ie the 4th pin of U2) of the second control chip (U2), and the control terminal is used for Controlling the connection between the common terminal and the normally closed terminal (NC, i.e. the third pin of U2) or with the normally open te...

Abstract

Embodiments of the present application disclose a bluetooth headset charging box and a bluetooth headset. The charging box comprises a first contact terminal and a second contact terminal. The secondcontact terminal is a ground terminal. The first contact terminal is connected to a common terminal of a first control chip. The control terminal of the first control chip is connected with an enableterminal of a controller chip of the charging box, and is used for controlling the common terminal to be connected with the normal-close terminal or connected with the normal-open terminal through theenable terminal of the microcontroller of the charging box. The normal-close terminal is connected to a signal terminal of the controller chip of the charging box. The normal-open terminal is connected to an output terminal of a charging power supply. By implementing the technical solution provided by the present application, the contact terminals of the bluetooth headset charging box and the bluetooth headset can be simplified into two, thereby reducing the difficulty of structural design of the headset, improving the stability of the headset in the charging box, and making the appearance ofthe headset more compact.

Description

technical field [0001] The embodiments of the present application relate to the technical field of wireless bluetooth earphones, in particular to a charging box for a bluetooth earphone and a bluetooth earphone. Background technique [0002] With the gradual improvement of the level of science and technology, wireless bluetooth earphones have been favored by the majority of users according to their lightness and portability. The box of the wireless Bluetooth headset has been changed from the previous only storage function to support the charging function. In order to enable the box to charge the earphones, the pins between the earphones and the box have also been developed from the original two contact terminals to three contact terminals. The three contact ends increase the difficulty of the structural design of the earphones, and have higher requirements for the stability of the earphones in the box, and also affect the simplicity of the appearance of the earphones. Con...
