Abstract: The present utility model relates to a loudspeaker, in particular to a loudspeaker and a loudspeaker shock absorption structure, which comprise a first elastomer for connecting with a loudspeaker body and a second elastomer for connecting with a loudspeaker fastener structure, the first elastomer and the second elastomer are connected by a cantilever, the cantilever is made of an elastic material. The present utility model forms a non-coaxial connection structure between the loudspeaker body and the loudspeaker fastener structure by setting a cantilever, so that a force produced by a vibration of the loudspeaker body cannot be directly transmitted to the loudspeaker fastener structure. Instead, the force is acted on the fastener structure in the form of a small force after being weakened by buffering and filtering via the cantilever, thereby greatly reducing a machine vibration caused by a large amplitude of the loudspeaker.
