Abstract: A portable keyboard includes a plurality of key assemblies including a plurality of key tops, a main body of a pillar shape of n angles, which is located in the vicinity of a first key assembly among a plurality of the key assemblies and includes a plurality of sides, a flexible connection member configured to connect a plurality of the key assemblies with the main body, and a main board configured to be embedded in the inside of the main body and process input signals inputted from a plurality of the key assemblies. In this case, the main body includes a first side of which one edge of the first side is connected with the flexible connection member, a second side adjacent to another edge of the first side and the second side of which an angle with the first side is equal to or greater than 90 degrees, and a cradle configured to combine one end of the cradle with the second side using a hinge to make the cradle to be rotated and the cradle configured to be contacted with the second side.

Abstract: A portable electronic equipment including a main body configured to be worn on a user's neck; a user input unit on the main body; a short-range wireless chipset loaded in the main body and configured to perform wireless communication with a host media device; and a controller configured to sense, via a sensor, whether or not the user is wearing the main body on their neck, and selectively control the short-range wireless chipset to perform the wireless communication with the host media device via a designated profile supported by the host media device and a function implemented by the host media device.
