Embodiment Construction

[0033] In the drawings, like numerals on different figures are used to indicate like elements throughout. Referring to FIG. 1 , there is illustrated a closeable wireless communication device 1 comprising a radio frequency communication unit 2 connected to communicate with a processor 3 . The device 1 also has an external user interface 5a with a screen 5c and a keypad 5b, and an internal user interface 6a with a screen 6c and a keypad 6b. The respective screens 5c, 6c and keypads 5b, 6b of the interfaces 5a, 6a are connected to communicate with the processor 3 . Also, it will be clear to those skilled in the art that the screens 5c, 6c may be touch screens, thereby making the keypads 5b, 6b optional. A housing position detector 19 is also connected to the processor 3 to provide a housing position signal (PS), the position detector 19 is typically a mechanically activated push-in push button switch, however, the position detector 19 may comprise for example a magnetic sensor (...

Abstract

The invention provides for a closeable radio communications device ( 1 ) comprising a housing ( 21 ) having at two portions ( 22,23 ) pivotally mounted to each other to allow relative movement of the portions between a closed position and an opened position. There is a spacing projection ( 30 ) on one of the two portions ( 22,23 ), the spacing projection ( 30 ) being configured such that when the housing ( 21 ) is in the closed position an acoustic chamber ( 31 ) is formed by an inner surface ( 32 ) of the projection and facing surfaces ( 27,28 ) of the respective portions ( 22,23 ). A speaker ( 5 d) mounted inside the housing ( 21 ) is in operative communication with the acoustic chamber ( 31 ).

Description

technical field [0001] The present invention relates to a closeable communication device having a two-part housing movable from a closed position to an open position. When in the closed position, the device provides an acoustic chamber that enhances the low-frequency acoustic characteristics of audio signals emanating from speakers typically fitted in the device. The invention is particularly useful for communication devices having a two-part housing movable about a pivot. Background technique [0002] Communication devices such as wireless or cellular (mobile) telephones, which are easily portable and support many features and functions, are becoming popular. One communication device that is easily transportable is a closeable (or foldable) cellular telephone with a two-part housing that can be moved from an open position to a closed position and vice versa. In the open position, the traditional cellular telephone user interface contains all the communication speakers, mi...
