摘要: An entertainment sound panel that serves foreground music and paging applications. The of the present invention is constructed honeycomb materials adhesives. driver mounted supported on a bridge structure spans its back side. interacts with through voice coil assembly. separated from by contact pad to deal shear problems between driver. Improvement in low frequency (bass) response provided butt joint lays next an adjacent isolation pad, can float freely. In another embodiment, provides lower cost flat radiator for end business applications where performance characteristics are less important than cost. polypropylene or similar material. As panel, Foam stabilizers positioned either side used set height structure.
