Description

Cellular pocket telecommunications device {Cellular handheld telecommunications device}

Various models of such cellular pocket telecommunication devices have been available in the prior art. For some specific examples, for example Motorola's MicroTAC series, one housing part contains all the necessary components (transceiver, battery, keypad, display, microphone, speaker, battery, antenna, etc.) The second housing part is only used as a lid or cover of the keypad. In this specific example, the second housing part is basically provided for the purpose of covering the surface and is not used for the purpose of containing the component.

In another specific example, for example Nokia's Communicator series, when closed, the two half housings completely obscure the keypad and display. Moreover, the device is relatively bulky and its form is not very ergonomic.

Another model type, for example Motorola's StarTac series, also has two bisected housings that form the housing. However, with the two bisected housings closed, the display (and keypad) is not visible. Moreover, the battery is embedded in an open state of use in an upper housing in a bisected housing in contact with the user's ear. Therefore, the device is relatively unbalanced because of its high center of gravity. In addition, in this type of telecommunications device, the (pullable) antenna is provided in the lower (other) housing of the bisected housing, which is inconvenient to hand.

The present invention relates to a cellular pocket telecommunications device, more particularly comprising a first housing portion and a second housing portion, wherein the second housing portion is connected to the first housing portion by a hinge means and thus comprises a first And a type of cellular pocket telecommunication device in which the second housing portion may or may not be folded together.

Other features, features, advantages and modifications of the invention are described in detail in the following description of the invention embodiments with reference to the accompanying drawings.

1 is a plan view of a cellular pocket telecommunications device according to the present invention in an open state.

FIG. 2 is a side view of the cellular pocket telecommunication device of FIG. 1.

3 is a plan view of the cellular pocket telecommunications device of FIG. 1 in a closed state.

4 is a side view of the cellular pocket telecommunication device of FIG. 3.

In view of the shortcomings of known devices, the underlying problem of the present invention is to provide a cellular pocket telecommunication device that is more user friendly and ergonomic than existing prior devices.

In order to solve this problem, there is provided a cellular pocket telecommunication device having a first and a second housing part, the second housing part of the device being connected to the first housing part by a hinge means so that the first and second housing parts are connected. The housing portion may or may not be folded together, the first housing portion being a microphone for receiving voice energy, a transceiver for transmitting / receiving voice and / or data signals to / from a cellular base station, to control operation of the device. A keypad for entering alphanumeric data and / or generating a message to be sent to the called party to enter a control command and / or to determine a party to be called, a control command entered via the keypad or a send Alphanumeric display for displaying alphanumeric data related to messages to be received or received And a battery for powering components of the device, the second housing portion including a speaker for producing a received voice signal, and an rf antenna for transmitting rf energy, and a second The housing portion is such that when the first and second housing portions are folded together, the alphanumeric display of the first housing portion is at least partially visible.

This unique idea offers a number of advantages over the prior art. First of all, when the two housing parts are in an unfolded (used) state, the microphone and the speaker are at an optimum distance. Moreover, the user can select the angle between the two half halves so that the user's individual needs for the distance between the microphone and the speaker can be tailored.

Secondly, even when the device is in the closed (standby) state, the display is at least partially visible, and as a result, incoming messages are easily visible.

Moreover, since the battery is provided in the same housing part as the transceiver, there is no need for a flexible (rotatable) power line connecting the two housing parts.

In addition, in use, the weight distribution between the two bisected housing portions of the device is provided to the user because the ″ heavy ″ side of the two bisected housing portions (including the battery, keypad, display and microphone) is within the palm of the user. It is more convenient.

This design improves rf energy transmission and reception because the antenna is provided in an upper housing ("lighter") in a half-separated housing of the device, where the antenna is virtually surrounded by the user's hands and head.

All these advantages arise directly from the unique idea according to the invention described above.

In a preferred embodiment of the invention, the second housing portion is adapted such that the keypad is at least partially accessible when the first and second housing portions are folded together. This feature allows easy access to the device's functionality. In the prior art with two bisected housing parts, the user has to open the device to operate the keypad, while the present invention operates the keypad without opening the device (message entry, modification of the phone book of the device, menu items provided in the device). The choice of their own). Thus, the device may be placed on the table in a closed (less prominent) state while continuously accessing (at least partially) its features.

In the presently preferred embodiment of the invention, the special key (eg arrow switch) is the only key accessible in the closed state of the device. Nevertheless, the software of the device controlling the menus and functions is designed so that the user can utilize all the selection functions by selectively operating this special key.

In another embodiment, the keypad is designed (at least partially) as part of the touch screen. Therefore, the proper functions of the device can be accessed even when the device is operating in the closed (standby) mode.

In another embodiment of the invention, when the device is located on the user's head with the first and second housing parts unfolded, the second housing part has an rf shield for protecting the user's head from rf radiation. Include. This feature is relatively difficult to achieve in a device in which the antenna is in a housing part containing all relevant parts of the phone, while the device according to the invention can very easily allow this function.

Alternatively, a conventional rod-shaped antenna can be provided in the first housing part, and the rf shield of the second housing part provides some protection against radiation going to the user's head.

Prior art designs require a relatively complex connection (Motorola Startack: Flexible Power Line, Nokia Communicator: Flexible Multiwire) to connect a component to two bisected housings, while in one embodiment, the invention It is shown that hinge means connecting the first and second housing parts are formed of two joints, which joints are provided on two opposite walls of the first and second housing parts, respectively.

More specifically, one of the joints includes a rotatable rf connection for connecting the rf antenna and the transceiver, and the other of the joints includes a rotatable electrical connection for connecting the speaker and the transceiver. The rotatable rf connection can be formed by coaxial male / female rf coupling. The connection for the speaker can also be formed in a similar manner.
