Abstract
In a wireless communication device 100, a preferably mesh, metal ground plane 314 serves both as an antenna ground plane or as an acoustic resistor for conditioning sound that passes through a sound port 120, 122. The metal ground plane 314 is located between a sound transducer 312 and a sound port 120, 122, but the metal ground plane 314 does not block sound due to openings in the mesh of the ground plane 314. The ground plane 314 permits an ear member 112 to be made thinner and reduces the number of parts required to manufacture the wireless communication device 100.
