AI Technical Summary
[0003]当前主流蓝牙耳机普遍采用内置不可拆卸电池设计，用户需通过充电盒或充电接口定期为电池补充电量，这种设计虽提升了便携性，但受限于锂电池的特性(如充放电循环次数、温度敏感等)，长期使用后电池容量会逐渐衰减，导致单次续航时间缩短，例如，中低端耳机在频繁充放电后，实际续航可能从最初的5-6小时降至3-4小时，需每日充电甚至多次补电，不仅影响使用体验，还可能因电池老化加速缩短耳机整体寿命，部分品牌通过优化电池管理算法或采用模块化设计(如华为部分型号)来缓解这一问题，但整体而言，电池续航仍是蓝牙耳机用户的核心痛点之一
[0013] 1. By setting up an ear shell, the inner cover of the ear shell can be removed during use, and the removable battery can be replaced, thereby improving the service life of the device.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of headphone technology, and in particular to a headphone with a detachable battery. Background Technology
[0002] In the current headphone technology field, Bluetooth headphones apply Bluetooth technology to hands-free headsets, allowing users to be free from the shackles of annoying wires and make calls freely and easily in various ways. Since its advent, Bluetooth headphones have been a great tool for mobile business people to improve efficiency.
[0003] Most mainstream Bluetooth headphones currently use a built-in, non-removable battery design, requiring users to periodically recharge the battery via a charging case or charging port. While this design improves portability, it is limited by the characteristics of lithium batteries (such as the number of charge-discharge cycles and temperature sensitivity), causing the battery capacity to gradually decrease over time, resulting in shorter battery life per charge. For example, after frequent charging and discharging, the actual battery life of mid-to-low-end headphones may drop from the initial 5-6 hours to 3-4 hours, requiring daily charging or even multiple recharges. This not only affects the user experience but may also accelerate the overall lifespan of the headphones due to battery aging. Some brands have mitigated this problem by optimizing battery management algorithms or adopting modular designs (such as some Huawei models), but overall, battery life remains one of the core pain points for Bluetooth headphone users.
