[0002] The removable shell of the headphone battery compartment battery is a design that allows the user to easily remove and replace the battery. This shell is usually designed to facilitate user maintenance and battery replacement, and can also extend the service life of the battery compartment. When the user needs to replace the battery, just open the removable shell, take out the old battery and put in the new battery;

[0003] A Chinese patent with publication number CN216600000U discloses a detachable Bluetooth headset battery structure, including a clamping block, a first spring is provided on one side of the clamping block, a strip opening is provided on one side of the cavity, a moving rod is provided inside the strip opening, a push rod and a push column are provided at the bottom of the moving rod, and a push groove is provided on the top of the clamping block. When the battery module is out of power, the moving rod can be moved to move the moving rod, so that the push rod and the push column move downward. At this time, the push rod will enter the inside of the push groove, so that the clamping block moves to one side and away from the battery module. At the same time, the push column will push the battery module away from the first groove of the main body, which is convenient for the replacement of the battery module and can be used for the battery compartment in time.
