The invention discloses a separable easy-to-mount loudspeaker. The separable easy-to-mount loudspeaker comprises an upper loudspeaker portion and a lower loudspeaker portion. The upper loudspeaker portion comprises an upper shell, a vibration membrane, a voice coil and a torsional cover. The lower loudspeaker portion comprises a lower shell and a magnet. The upper loudspeaker portion and the lowerloudspeaker portion are fastened through threads, and are sealed through butt joint between a groove and a block. The vibration membrane is fastened through non-resin adhesion, and is clamped elastically by a rubber sound-absorbing ring. The separable easy-to-mount loudspeaker has the advantages that the structure is simple, and the design is reasonable; the loudspeaker is divided into the upperportion and the lower portion which are produced on different lines, so that convenience in mounting is achieved, and error-tolerant rate is increased; the vibration membrane is clamped elastically, so that proneness to loosening and separation is avoided, and service life is prolonged on the premise of guaranteeing tone quality; time limitation for resin curing is avoided, and production efficiency is improved.
