Abstract

The invention provides an adjustment control circuit. The adjustment control circuit comprises a voltage input end and a voltage output end; when the adjustment control circuit receives a first outputvoltage from the voltage input end, the first output voltage is compared with a reference voltage, and if the reference voltage is smaller than the first output voltage, the first output voltage is reduced and output from the voltage output end; and if the reference voltage is greater than the first output voltage, the first output voltage is increased and the first output voltage is output fromthe voltage output end. The invention further provides a Bluetooth headset, a charging box and a charging system comprising the adjustment control circuit.

Description

technical field [0001] The embodiment of the present application relates to the technical field of charging, and in particular to the technical field of charging a Bluetooth headset. Background technique [0002] With the popularization of consumer electronic products, wireless bluetooth earphones are favored by many consumers, but various problems encountered in the use of bluetooth earphones have not yet been well resolved. Contents of the invention [0003] In order to solve the foregoing technical problems, the present application provides an adjustment control circuit, a Bluetooth earphone, a charging box and a charging system to improve charging efficiency. [0004] In an embodiment of the present application, an adjustment control circuit is provided, including a voltage input terminal and a voltage output terminal. When the adjustment control circuit receives a first output voltage from the voltage input terminal, it compares the first output voltage voltage and a...
