Patent ID: 8032090

Claim:
An apparatus comprising: headphones including a pair of earpieces to provide audio signals to a user, the headphones separate from and connectable to a portable system, the headphones further having a cabling portion that in turn is to couple to the portable system including an amplitude modulation (AM) radio receiver, the cabling portion further including an AM antenna, wherein the AM antenna is located at a distal portion of the cabling portion with respect to the earpieces; and an external connector coupled to the distal portion of the cabling portion to connect the pair of earpieces to the portable system, wherein the external connector includes a pair of audio contacts to provide audio signals to the earpieces, an antenna contact to provide an AM signal from the AM antenna to the AM radio receiver, and a ground contact, wherein the portable system does not include an AM antenna and includes an FM antenna, and is to automatically detect presence of the AM antenna when the headphones are coupled to the portable system, and is to detect no presence of the AM antenna if a tuning algorithm indicates an incoming signal is out of scale.
