Definitions

  • the present invention is related to a cellular handheld telecommunications device, and more specifically to the type of cellular handheld telecommunications device where the device is contained in a first and a second part of a housing with the second part of the housing being connected to the first part of the housing by a hinge means such that the first and second parts of the housing can be folded together or unfolded.
  • one part of the housing contains all the essential components (transceiver, battery, keypad, display, microphone, speaker, battery, antenna etc.), while the second part of the housing only serves as a lid or cover of the keypad.
  • the second part of the housing is basically provided for cosmetic reasons and does not serve as a containment for components.
  • the two halves of the housing entirely conceal the keypad and the display.
  • the device is relatively bulky and its shape is not very ergonomic.
  • Yet another type of models also has two halves that form the housing. However, in the closed position of the two halves, the display (and the keypad) is not visible. Moreover, the battery is integrated into the upper half of the housing which - in the opened use position - is held against the ear of the user. Thus, this device is relatively unbalanced due to a high centre of gravity. Moreover, in this device, the (extractable) antenna is provided in the lower (other) half of the housing, also resulting in cumbersome handling.
  • the problem underlying the present invention is to provide a cellular handheld telecommunications device which is more user friendly and more ergonomic than the prior art devices.

  • the display is (at least) partly visible, so that incoming messages or the like are readily visible.
  • the battery is provided in the same part of the housing as the transceiver, there is no requirement for a flexible (rotatable) power line connecting the two parts of the housing.
  • the weight distribution between the two halves of the device is more convenient for the user since in use, the "heavier" half (containing the battery, the keypad, the display and the microphone) lies in the palm of the user's hand.
  • the rf energy transmission and reception is improved over a design, where the antenna is virtually surrounded by the user' hand and head.
  • the second part of the housing is dimensioned such that when the first and second parts of the housing are folded together, the keypad is at least partly accessible.
  • This feature allows for an easy access to the functionality of the device. While in prior art devices having two halves, the user must open the device in order to operate the keypad, the invention allows to operate the keypad (enter messages, edit the telephone directory in the device, select menu items provided in the device etc.) without having to open it. Hence, the device can be put on a table in its closed (less prominent) position while still allowing to access (at least a part of) its features.
  • a special key e.g. a cross switch
  • the software in the device controlling the menu and its functions is so designed that the user has all options available by selectively operating this special key.
  • the keypad is (at least partly) designed as a part of a touch screen. Hence, relevant functions of the device are accessible while the device is in its closed (Standby) mode of operation.
  • the second part of the housing contains an rf shielding to protect a user's head against rf radiation when the device is held at user's head with the first and second parts of the housing unfolded. While this feature is relatively difficult to achieve in a device where the antenna is in the part of the housing containing all relevant parts of the telephone, the device according to the invention allows for this option very easily.
  • a conventional rod type antenna could be provided the first part of the housing and rf shielding in the second part of the housing provides some protection against radiation into the user's head.
  • the present invention teaches that the hinge means connecting the first and second parts of the housing is formed by two joints, and that the joints are provided at two opposite walls of the first and second parts of the housing, respectively.
  • one of said joints comprises a rotatable rf connection to connect said rf antenna and said transceiver, and another of said joints comprises a rotatable electrical connection to connect said speaker and said transceiver.
