Communication device including one or more electrical control buttons in an upper housing part

摘要

Folding wireless communication devices ( 100, 700 ) comprise first parts ( 102, 1002 ) that are rotatably coupled to second parts ( 104, 1104 ). The first parts ( 102, 1002 ) can be moved from first positions in which the first parts ( 102, 1002 ) overlie the second parts ( 104, 1104 ) to second positions in which the first parts ( 102, 1002 ) extend upward away from the second parts ( 104, 1104 ). The first parts ( 102, 1002 ) comprise one or more buttons ( 302, 304, 306, 308 1010, 1012 ), e.g., a pair of directional buttons, such as "UP" and "DOWN" control buttons ( 302, 304, 1010, 1012 ). Hardware and/or software is used to change the function of the buttons ( 302, 304, 306, 308 1010, 1012 ) depending on the position of the first parts ( 102, 1002 ).
