Abstract
A combined audio and power connector facilitates the use of portable audio devices with audio systems, including but not limited to vehicle audio systems. By integrating an audio input and a power supply into a single connector, the need to use multiple cords, e.g., one for the power supply and another for the audio input, is avoided. Further, a vehicle can deliver power to many types of portable devices without the use of relatively large auxiliary power jacks. As a result, many or most of the auxiliary power jacks currently incorporated in vehicle designs can be eliminated, making additional space available for other applications.
Claims13
An electrical interface comprising:
- a cord comprising a plurality of conductors, a portion of the cord divided into a first branch comprising a first subset of the conductors and a second branch comprising a second subset of the conductors;
- an audio connector coupled to the first branch and arranged to conduct an audio signal;
- a power connector coupled to the second branch and arranged to conduct a power signal;
- and
- a third connector coupled to the cord and arranged to conduct the audio signal and the power signal.
An electrical connector comprising:
- at least one audio segment arranged to conduct an audio signal;
- a power segment housed with and electrically isolated from the at least one audio segment and arranged to conduct a power signal;
- and
- a common segment housed with and electrically isolated from the at least one audio segment and the power segment and arranged to provide a return path for the audio signal.
An audio system comprising:
- an electrical receptacle comprising
- a power segment coupled to a power supply;
- at least one audio segment coupled to an audio input of the audio system and arranged to conduct an audio signal from an external audio device to the audio system, the at least one audio segment electrically isolated from the power segment;
- and
- a common segment electrically isolated from the at least one audio segment and the power segment and arranged to provide a return path for the audio signal.
