[0016] In the following description, specific details are set forth in order to provide a thorough understanding of the embodiments of the present application. However, persons skilled in the art should understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary details.

[0017] It should be understood that when used in the specification and the appended claims of the present application, the term "comprising" indicates the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0018] Please refer to Figure 1, like the original outdoor sound equipment, often equipped with the corresponding battery 1 power supply, the sound equipment 1 can only work in a single power mode, when the sound access wired power supply, its built-in battery 1 may be charging and discharging at the same time, resulting in battery 1 life shortening, based on the above problems, the embodiment of the application discloses a kind of prolonging the service life of outdoor sound equipment battery 1 circuit, including sound equipment and battery 1, the battery 1 is electrically connected with electronic switch 2, the electronic switch 2 and built-in AC-DC power supply 3 are electrically connected, when AC-DC power supply 3 access 220V wired power supply 4, battery 1 stops power supply.The battery 1 is electrically connected with charging management module 5, and the charging management module 5 is electrically connected with external DC power supply 6.
