Title: OMNIDIRECTIONAL LOUDSPEAKER BOX AND MANUFACTURING METHOD THEREFOR
Abstract:
An omnidirectional loudspeaker box comprises a set of loudspeaker modules (20) uniformly disposed in an annular configuration. Each loudspeaker module (20) comprises an active vibration unit (21) and a passive vibration unit (22). The active vibration units (21) are uniformly disposed in an annular configuration. The passive vibration units (22) are uniformly disposed in an annular configuration. The active vibration units (21) can respond to the input of external signals and drive the passive vibration units (22) to vibrate together, thereby generating improved sound quality and effect.
