Abstract
A speaker includes a speaker body and a diaphragm. The diaphragm is a planar structure. The speaker body includes a positioning structure. The positioning structure has a cavity penetrating front and back sides of the positioning structure. The diaphragm is positioned on the positioning structure. The diaphragm is in the form of a planar structure, instead of a curved or spherical structure. The planar structure of the diaphragm is simplified, so that the manufacturing process of the diaphragm is simpler.
