Abstract

The invention is applicable to the technical field of Bluetooth earphones, and provides an automatic startup and shutdown circuit and a Bluetooth earphone, and the automatic startup and shutdown circuit comprises a power supply enabling port, a shutdown control signal output port, a startup control signal output port, a positive power supply input port, a first capacitor, a pull-down module, a pull-up module and an electronic switch module. The power supply enabling port is added to serve as a detection end for putting in or taking out the charging box, and the Bluetooth earphone is controlledto be turned on or off according to signals output by the turn-off control signal output port and the turn-on control signal output port. The automatic startup and shutdown circuit is not limited towhether the charging box is powered on or not, and no matter whether the charging box is powered on or not, the Bluetooth headset can be put into the charging box to be automatically shut down and taken out of the charging box to be automatically started up. A user does not need to care about whether the charging box is powered on or not and only needs to operate the Bluetooth headset according tonormal habits, so that the Bluetooth headset can be turned on or turned off, and the user experience is greatly enhanced.

Description

technical field [0001] The application belongs to the technical field of bluetooth earphones, and in particular relates to an automatic switch circuit and a bluetooth earphone. Background technique [0002] At present, existing Bluetooth headsets, especially Bluetooth TWS headsets, such as Qualcomm Bluetooth TWS headsets, have two pins VBUS and GND on the headset, and the headset can be turned off and charged when the headset is placed in the charging box. Turn on the phone and connect to the phone. The above situation is based on the normal situation that there is electricity in the charging box. However, in the special case of no electricity in the charging box, the earphones cannot be automatically turned off when they are placed in the charging box, and cannot be turned on automatically when they are taken out of the charging box. In some cases, the switch can only be realized by pressing the mechanical button on the headset, which greatly reduces the user experience. ...
