Abstract

The invention relates to the technical field of charging of electronic products, in particular to an innovative battery compartment structure for a wireless Bluetooth headset. The structure comprises a buck-boost power supply module for converting an input voltage into an output voltage and outputting the output voltage from an output voltage end; a first earphone charging branch which comprises a first linear charger and a first lithium battery which are connected between the output voltage end and the grounding end; a second earphone charging branch which comprises a second linear charger and a second lithium battery which are connected between the output voltage end and the grounding end; wherein the output voltage of the output voltage end is 0.1 V higher than the voltage of the first lithium battery, and the voltage of the second lithium battery is equal to the voltage of the first lithium battery and is parallel to the first lithium battery. Due to the adoption of the chip architecture, the output voltage can be flexibly adjusted according to the voltage of the battery to be charged, and the voltage drop loss in a straight-through mode does not exist, so that the charging efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of charging electronic products, in particular to an innovative battery compartment structure for wireless bluetooth earphones. Background technique [0002] Nowadays, True Wireless Stereo (TWS) earphones have replaced traditional wired earphones because of their convenience, and have become more and more common in people's daily life. Wireless Bluetooth connection is established, so in order to support Bluetooth connection, the headset itself is also attached with a battery module. Due to the increase of battery modules, charging has become a new problem. Therefore, in order to solve the charging problem of earphones, earphones are generally equipped with earphone charging compartments, so the design of earphone charging compartments has also become a very important part. [0003] At present, the typical TWS earphone battery compartment power management architecture is one boost switching power supply plus...
