Abstract
A connector for receiving a cylindrical plug includes a body defining a plug aperture and a cavity for receiving the cylindrical plug. A plurality of electrical contacts in communication with the cavity make electrical connections with the cylindrical plug and retain the cylindrical plug. A microphone is coupled to the body such that the plug aperture and the cavity provide an acoustic path to the microphone. The microphone may be at an end of the connector opposite the plug aperture or on a side of the connector adjacent the plug aperture. The connector allows a microphone to be added to a device, such as a mobile telephone, without the need for an additional external aperture. The microphone in the connector may operate with a second microphone and processing electronics in the device to provide audio processing functions such as noise cancellation or audio beamforming.
