Abstract:
The present application discloses a loudspeaker and an electronic device. The loudspeaker comprises: a first shell, having a sound outlet channel formed therein; a second shell, connected to the first shell to form a first cavity; and a loudspeaker core, arranged in the first cavity, and dividing the first cavity into a front cavity and a rear cavity after the loudspeaker core is connected to the first shell, wherein the front cavity is communicated with the sound outlet channel, and the rear cavity is a sealed cavity. Raw material components of the first shell and the second shell comprise: 50-90wt% of a polymer composite material and 10-50wt% of a hollow sphere material. 10-50wt% of the hollow sphere material is added into the raw material components of the first shell and the second shell, so that the density of the first shell and the second shell can be reduced, and thus the weight of the first shell and the second shell is reduced.
