A knockdown speaker mainly comprises a magnetic circuit base, a casing, and a vibration unit. The magnetic circuit base is substantially a hollow body having a projecting cylinder at center and a plurality of fixing holes in its top rim. The vibration unit is composed of a funnel-like cone socket and a damper set, which are formed by combining a bottom end and a top end of the vibration unit respectively with a sound ring set or a piece of drum paper. The magnetic circuit base is mounted on the bottom rim of the casing. The vibration unit is jointed with the magnetic circuit base via the sound ring set arranged at the bottom end of the vibration unit to form a consolidated knockdown speaker.
