Abstract
An electronic device includes a housing, a mounting sheet, a circuit board mounted to the housing and the mounting sheet, and a loudspeaker module mounted on the mounting sheet. The housing defines a first receiving chamber and a second receiving chamber communicating with the first receiving chamber at one end of the housing, and a first sound hole corresponding to and communicating the first receiving chamber. The loudspeaker module includes a first loudspeaker which is received in the first receiving chamber. The first receiving chamber communicates the second receiving chamber to form a resonant cavity for the first loudspeaker. The sounds emitted by the first loudspeaker transmit to the outside of the housing by the first sound hole.
