Abstract
A speaker structure includes a membrane, an electrode which has a plurality of holes, a frame holding member and at least one set of supporting members. The frame holding member forms an exterior shape of the speaker structure and holds the membrane and the electrode at two opposite sides. Each of the set of the supporting members has a geometric structure and is placed in a space opposite to a soniferous hole region between the electrode and the membrane, so as to prevent the membrane and the electrode from contacting.
