Abstract:
1. A reduced size mobile communication device comprising: a housing structure comprising a contoured case having a base wall with an exterior surface and interior surface for carrying subassemblies defining an operational communication device; speaker means for producing audible sounds; antenna means for transmitting RF signals; camera sensor means for capturing an image; cavity means within said housing structure for carrying said speaker means and said antenna means and said camera sensor means, said cavity means further defining an antenna support structure having a substantially sealed common shared chamber comprising multiple acoustic cavities in communication with one another and further comprising a first chamber defined between an upper wall portion of said antenna support structure and a printed circuit board (PCB) positioned a spaced distance below said upper wall portion, a second chamber defined between said PCB and a ground plate positioned a spaced distance below said PCB, a third chamber defined between said base wall and said ground plate positioned a spaced distance above said base wall, said speaker means carried in said third chamber and said camera sensor means carried in said first chamber, said first and second chambers providing a controlled back cavity defining an acoustic resonator chamber to provide a desired acoustic characteristic from said speaker means.
