Abstract: A dual suspension edge member structure for a radiation device, a dual suspension edge loudspeaker and a loudspeaker box. The radiation device comprises an outer supporting frame, a vibration element, a first suspension edge member extending between the vibration element and the outer supporting frame, an inner frame connected to the vibration element, an outer holding frame, and a second suspension edge member connected between the inner frame and the outer holding frame. The dual suspension edge member structure of the radiation device for making the dual suspension edge loudspeaker or loudspeaker box prevents shaking and shifting of the vibration element to improve the sound effect quality.

Abstract: An omnidirectional loudspeaker box comprises a plurality of loudspeaker modules uniformly disposed in an annular configuration. Each loudspeaker module comprises one or more active vibration units and one or more passive vibration units. The one or more active vibration units are uniformly disposed in an annular configuration. The one or more passive vibration units are uniformly disposed in an annular configuration. The one or more active vibration units can respond to the input of external signals and drive the one or more passive vibration units to vibrate together, thereby generating improved sound quality and effect.
