ABSTRACT:
In a wireless communication device100, a preferably mesh, metal ground plane314serves both as an antenna ground plane or as an acoustic resistor for conditioning sound that passes through a sound port120, 122. The metal ground plane314is located between a sound transducer312and a sound port120, 122, but the metal ground plane314does not block sound due to openings in the mesh of the ground plane314. The ground plane314permits an ear member112to be made thinner and reduces the number of parts required to manufacture the wireless communication device100.
