Abstract

A magnetic floating speaker includes a seat having a shell and a magnetic floating controller and a lower magnet both received in the shell. A floating member floating and located above the seat has a cover, a bass unit, two full range units and an upper magnet all received in the cover. The magnetism of the upper magnet and the lower magnet is mutually exclusive. The bass unit is surrounded by said two full range units and faces to a first direction, said two full range units face to a second direction and a third direction respectively which located at two sides of the first direction, the second direction and the third direction each forms an acute angle with the first direction respectively.

Claims
