▎ 摘　　要

NOVELTY - Speaker comprises a first shell (100) is provided with a sound outlet channel. A second shell (200) is fastened and connected with the first shell to form a first cavity. A speaker core is disposed in the first cavity and after the speaker core is connected to the first shell. The first cavity is divided into a front cavity and a rear cavity. The front cavity communicates with the sound outlet channel and the rear cavity is a sealed cavity. The raw material components of the first shell and the second shell comprises 50-90 wt.% high molecular complex material and 10-50 wt.% hollow sphere material. USE - Used as speaker. ADVANTAGE - The speaker: satisfies the reduction requirement and ensures the reliability of welding; can be compatible with different characteristics of various polymer material e.g. crystalline polymer material and semi- crystalline polymer material and can be reduced the density of the first shell and the second shell, thus reducing the weight of the first shell and the second shell. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an electronic device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the speaker. 100First shell 200Second shell
