Abstract
Methods and apparatus are provided for connecting together two audio components that have different size connectors and/or a different configuration of electrical contacts between them. In one embodiment of the present invention, an audio adaptor is designed having an audio plug of one size to mate with a first electrical device, such as an integrated mediaphone such as the iPhone™, and an audio jack having a different size to mate with a second electrical device, such as a conventional cell phone headset having a single earpiece. In that instance, the plug would be a four-prong, 3.5 millimeter stereo device, while the jack would be a three-prong, 2.5 millimeter monaural device. The adaptor includes circuitry that takes one audio channel (i.e., the left or right channel), and couples it to the audio input on the monaural jack.
