BACKGROUND
1. Field
The present disclosure relates to a controller and, more particularly, to a controller for the iPod shuffle.
2. Description of Related Art
The iPod shuffle® (registered trademark of Apple Inc.) is a digital audio player without volume or track controls on the device itself. The iPod shuffle includes a 3.5 mm four-conductor (i.e., four contact) female TRRS (tip, ring, ring, sleeve) connector (also known as a four-conductor jack socket) to which dedicated Apple headphones with a 3.5 mm four-conductor male TRRS connector (also known as a four-conductor jack plug) can connect. The dedicated Apple headphones provide volume and track controls for controlling the iPod shuffle.
If a user would like to use headphones other than the dedicated Apple headphones, the user loses the ability to control the volume and the track played by the iPod shuffle. As such, there is a need for a device that allows a user to use headphones other than the dedicated Apple headphones while providing volume and track control for the iPod shuffle. Furthermore, there is a need for a device that protects the iPod shuffle while still providing volume and track control.
