Abstract:
1. A speaker system comprising: a cabinet; at least one speaker unit attached to the cabinet; and a passive radiator attached to the cabinet, the passive radiator including a diaphragm and a supporting system supporting the diaphragm in a manner which allows the diaphragm to vibrate, wherein a part of a cross-sectional shape of the supporting system of the passive radiator and another part of a cross-sectional shape of the supporting system of the passive radiator are shaped to be substantially symmetrical to each other about a surface to which the supporting system of the passive radiator is attached so that the supporting system is configured to cancel a distortion component of a sound pressure radiated from a portion of the supporting system of the passive radiator with a distortion component of a sound pressure radiated from another portion of the supporting system of the passive radiator.
