Abstract: A headphone and earbud device for receiving an audio signal may include a headphone including a speaker acoustic device to amplify the audio signal and to define a speaker chamber to cooperate with an aperture and an earbud to be detachably connected to the speaker chamber to transmit the audio signal to the speaker chamber.

Abstract: In accordance with example embodiments of the present disclosure, the invention allows effective sending and receiving of radio signals commonly associated with those sent and received by antennas. The utility of the invention includes a versatile antenna wire comprised of an embedded formed electrical conductor within a protective, non-electrically conductive sheath or structural element that facilitates shorter-than-typical antenna designs. The versatile antenna wire can facilitate antenna radiators that are up to 80 percent shorter than traditional wire radiators—while still providing exceptional operating characteristics. In some embodiments, the antenna wire is a specifically contoured conductive material. Electrically conductive material may be wire; metalized tape; metalized foil; electrically conductive polymer; or conductive ink or coating.
