An expandable socket for attachment to a portable media player or a portable media player case. The expandable socket generally includes a platform, a skin coupled to the platform, a button coupled to the skin opposite the platform, and a biasing element. The skin includes an outer wall, an inner wall spaced radially inward of the outer wall, and a cavity defined by the inner wall, wherein the skin is deformable between a collapsed configuration and an expanded configuration. The biasing element is arranged within the cavity of the skin between the platform and the button, such that the biasing element is at least partially surrounded by the inner wall of the skin. The biasing element is configured to bias the skin into the expanded configuration.

A torsion coil spring supporting structure includes a first supporting portion opposing one end of a torsion coil spring with respect to an axial direction of the torsion coil spring; and a second supporting portion opposing the other end of the torsion coil spring with respect to the axial direction. The first supporting portion includes a spring supporting portion cooperative with the second supporting portion to support the torsion coil spring at a mounting position. The first supporting portion is elastically deformable, by moving the torsion coil spring, to permit the torsion coil to move to the mounting position in a direction crossing the axial direction and elastically restorable to place the spring supporting portion in an inner diameter portion of the torsion coil spring, thus supporting the torsion coil spring at the mounting position.

Connectors having contacts that can be highly corrosion resistant, can conserve precious materials, and can be readily manufactured. Examples can provide connector contacts that are highly corrosion resistant. These contacts can be formed of a precious metal or a precious-metal alloy. The precious-metal alloy can be a high-entropy alloy. To conserve the precious materials, a contact can be formed by a stamping a structure that becomes the contact, instead of stamping the contact from a structure. The structure can be a rod. To conserve the precious materials, only contacts that convey high voltages, such as power supplies, might be formed of the precious materials.
