Description

A communication apparatus having foldable and turnable housing members

The present invention relates to the field of mobile communications. More specifically, the present invention provides a communication device including a first housing member and a second housing member, wherein the first housing member and the second housing member have a first housing member with respect to the second housing member. A communication device is mechanically interconnected so that it can be folded and redirected.

Typical examples of communication devices according to the above-mentioned descriptions are mobile terminals for existing mobile communication systems such as GSM, D-AMPS, CDMA2000 or UMTS. Traditionally, the design of mobile terminals has often been based on a single device housing member that includes all components of the mobile terminal, including a display, keypad, antenna, microphone, speaker, battery and several electronic circuits. Such a design is often referred to as a "monoblock."

One trend in the field of mobile terminals is miniaturization in that the actual size and weight of mobile terminals have continued to shrink since they were made decades ago. The other trend is no longer just a tool for voice communication between two parties: messaging (SMS, e-mail, MMS), calendar, phone book, still and video imaging (camera), Internet browsing (WAP, WWW), video games. Increased and expanded functionality of mobile terminals to further provide services such as e.g.

In accordance with the above-mentioned trends, the display and / or keypad are protected and the mobile terminal can be folded to a closed position in a period of time not in operation such that the mobile terminal occupies a small amount of real space, and The keypad may be folded so that it is not folded into an open position that is adopted while the mobile terminal is in operation for easy access by the user, that is, several housings pivotably hinged to one other housing member. Model mobile phones are known. US-5,923,751 discloses an example of a collapsible mobile terminal according to the prior art. In addition, although mobile terminals are known in which the two housing members are reciprocally interconnected rather than collapsible, the principles of the mobile terminals are similar to collapsible mobile terminals. One example of such a mobile terminal is provided in US-5,485,517.

More recently, mobile terminals with built-in camera capabilities have been popularized. The camera of such mobile terminals can provide the user with image and / or video recording capabilities. Even more recently, first and second housing members which are not only foldable interconnected but also reciprocally interconnected via a biaxial hinge assembly coupling the first housing member to the second housing member Genie camcorders have been introduced in the form of camcorders. Typically, the first housing member includes a large display, while the second housing member has arrow keys, as well as conventional phone keys such as 0-9, *, #, answer / yes, end / no and delete. , A keypad including additional keys for controlling a graphical user interface, such as 4 / 5-way navigation keys, soft keys and the like. The camera lens is usually located at the second housing member or at the biaxial hinge. Because of the biaxial hinge arrangement, a user uses the mobile terminal as a collapsible conventional terminal (" flip phone ") for voice communication, messaging, internet browsing, and the like, and then the image to record images or video. When using a mobile terminal, the first housing member (with the display of the mobile terminal) can be redirected to a convenient angle position with respect to the second housing member. In addition, the user can close the mobile terminal by folding the first and second housing members together for convenient storage during periods of non-operation.

Some known collapsible and reversible mobile terminals allow the terminal to be folded into a closed position where the display is folded outwards rather than inwards as in the case of conventional collapsible terminals. The display can also be seen when the terminal is in the closed / folded position of the terminal. In this way, the user can, for example, read the current date or time, the current battery charge level, the notification of an incoming message or the telephone number of the incoming call (or even the caller's name associated with that telephone number if it exists in the phone book). An opportunity is provided for monitoring the mobile terminal. However, in order to use most of the services provided by the mobile terminal, the user must open / close the terminal without causing the housing member having the keypad to be redirected to a position where the keypad is easily accessible. Therefore, when a user initiates an outgoing phone call, initiates an internet browsing session, records a new outgoing message, plays a video game, and wants to access a calendar, the user first opens such an open / unfolded / redirected call. You can't do this without doing the operations. Such essential manual intermediary steps are considered inconvenient for many users.

In view of the above-mentioned description, it is an object of the present invention to solve or at least reduce the problems discussed above. In particular, one object is a foldable and reversible communication device (e.g. mobile terminal), which pivots the first housing member and the second housing member relative to one another and communicates in most of the different operating positions. By using the services or applications of the device it is to provide a communication device that gives the user a great deal of flexibility with respect to the selection of different operating positions. More specifically, one object is a communication device that can be used in a folded compact position and in several unfolded / open and redirected operating positions, in particular for the user to be able to access even in a compact position where a plurality of services are folded.

In the closed position, when the mobile terminal 1 is turned on, the mobile terminal 1 is audibly and via a call alert signal (call tone, melody, etc.) as well known in the art. You will receive incoming phone calls that can be displayed visually through the call indicator. If the volume down key 201 is pressed for a long time, a call alert signal for an incoming call may be silenced. Moreover, accessories can be connected to the mobile terminal 1 via an accessory connector 203 in the closed position. The mobile terminal 1 may be charged via the charging terminal 204.

Compact location

The second operating position is the compact position, which is the position shown in FIGS. 2A and 2B. As in FIGS. 1A and 1B, the first housing member 100 and the second housing member 200 are folded relative to each other, but here the first housing member 100 is in a closed position compared with its position. It is turned by an angle of 180 degrees. The front face 100a is facing outward and the user has full access to the display 110 as well as the first set of keys 120. Thus, although the compact position occupies almost as much real space as the closed position, although the second key set 220 is provided because the first key set 120 is provided below the display 110 in the front face 100a. Although not easy to access as shown in FIG. 2A and FIG. 2B, the services 340-346 of the mobile terminal are easily accessible to the user. In particular, function keys 122 and 123 to which useful functions are dynamically assigned depending on the currently running application or sub-routines of such an application, and a navigation key to allow multi-directional navigation and selection functions in the human-machine interface 334. 121 provides the user with full access and control opportunities for the services 340-346.

For example, a user may browse the Internet through an internet browser 340, read and write messages through a messaging application 346, and through a phonebook application 342 or a separate telephone application, Optionally, an outgoing telephone call may be made via voice activated dialing rather than manual entry. The user may also receive and answer incoming telephone calls, preferably by pressing the left function key 122, which causes the answering function to be assigned upon detection of the incoming call. The user may also record an image or video via the camera / image application 344.

Open position

The third operating position is the open (unfolded) position, which is the position shown in FIGS. 3A and 3B. Here, the first housing member 100 and the second housing member 200 are not folded facing each other in a position similar to the general operating position of the collapsible (flip type) terminal. Thus, in this position, the first key set 120 and the second key set 220 are accessible to the user. All services available at the compact location are also available at the open location, in addition the user can also advantageously use the second key set 220. For example, these keys may facilitate entry of numbers in the phone application or calculator application (when dialing a new phone number), may facilitate entry of text in a messaging application or word processing application, and video games. May be provided as control keys in applications. Moreover, the answer / yes key and the end / no key can be conveniently used to initiate, end and reject phone calls.

When the user wishes to switch the terminal 1 to an open position of the terminal 1 (eg from a compact position or a closed position), the terminal automatically changes profiles (eg, from the human-machine interface 334) (eg , Changing call alert signals, display background pattern / color), turning on the display, automatically answering an incoming call, and so on. Similar operations can be performed when the terminal 1 is switched from the open position of the terminal 1.

Camcorder position

The fourth operating position is the camcorder position, which is shown in Figs. 4A and 4B. Here, the first housing member 100 and the second housing member 200 are not folded facing each other by about 90 degrees. In addition, the first housing member 100 is redirected relative to the second housing member 200 by an angle of about 90 degrees as compared to the position of the second housing member 200 in the open position. Both the first key set 120 and the second key set 220 are accessible and can be used depending on the application.

Camcorder position is particularly useful for the camera / image application 344 and allows the user to record images or video while using the display as a recording monitor for convenience. As can be seen in FIGS. 4A and 4B, the display 110 is oriented in one direction to the user, while the camera 205 is away from the user in the opposite direction and toward the target object to be recorded. Volume up and down keys 201 on the side of the second housing member 200 are zoomed in and zoomed out during image or video recording (digital and digital depending on the capabilities of the camera 205). And / or optical zoom). Push to talk key 202 can be used to start and stop recording. Moreover, first key set 120 may also be used in camera / image application 344. For example, the navigation key 121 can be used for example when the recorded image is enlarged and all parts of the image may not be visible in the display at the same time, or various setting options related to image or video recording and processing (resolution , Color depth, brightness, saturation, etc.) can be used to pan or scroll in the recorded image. The function keys 122 and 123 may represent operations that are widely used in the camera / image application 344, for example.

The mobile terminal 1 may be adapted to automatically launch the camera / image application 344 when the camcorder position is entered.

Self-portrait position

The fifth operating position is a self-portrait position, which is shown in FIGS. 5A and 5B. Here, the first housing member 100 and the second housing member 200 are not folded facing each other as in the camcorder position. However, here, the first housing member 100 is turned relative to the position of the first housing member 100 at the camcorder position by about 180 degrees. Thus, in contrast to FIGS. 4A and 4B, display 110 and camera 205 are directed in the same direction to the current user. Thus, the locations illustrated in FIGS. 5A and 5B are particularly suitable for recording of self-portraits (still images) or even video captured by the user himself.

The keys 201 and 202 and the second set of keys 120 can be used in a similar manner as in the camcorder position.

The mobile terminal 1 is displayed on the display 110 in order to make the image displayed on the display 110 intuitive to the user upon transitioning from the camcorder position to the self-portrait position or vice versa. It can be adapted to automatically flip the image vertically (upside down and upside down) and also horizontally.
