Abstract
A first enforcing rib, a second enforcing rib, and a third enforcing rib are integrally formed at least at one of a front side and a back side of a diaphragm, the first enforcing rib being formed as an aggregate of a plurality of hexagons, enhancing strength and achieving light weight of a speaker using the diaphragm, preventing a difficulty of the speaker in emitting an audio sound.
