Abstract
A speaker box and an electronic device are disclosed. The speaker box includes an upper cover plate including side walls, a first lower cover plate, a speaker unit, a motor module, and second lower cover plates. The speaker unit divides an accommodating cavity defined by upper cover plate and first lower cover plate into front and back cavities. The second lower cover plates are assembled with the upper cover plate to define compensation cavities. A length of at least one of the side walls of the upper cover plate is greater than that of an orthographic projection thereof, so the speaker box is suitable for various electronic devices and has strong adaptability and wide application. The compensation cavities are communicated with the back cavity, which increases an overall space of the back cavity, improves low-frequency performance of the speaker unit, and improves sound production effect of the speaker unit.
