Abstract
A speaker box and an electronic device include an upper cover plate, a lower cover plate, a speaker unit, and a motor module. The speaker box define an accommodating cavity for accommodating the speaker unit and the motor module. The speaker unit divides the accommodating cavity into a front cavity and a rear cavity. The motor module is disposed on one side, distal from the upper cover plate, of the speaker unit. The upper cover plate includes a top wall and side walls. A length of at least one of the side walls of the upper cover plate is greater than a length of orthographic projection of the at least one of the side walls thereof. Edge areas of the upper cover plate and edge areas of the lower cover plate are assembled to define compensation cavities. Therefore, low-frequency performance of the speaker box is improved.
