Direction control type key position function switching device of handheld device

Abstract

The invention relates to a direction control type key position function switching device of a handheld device, the handheld device comprises a housing, the housing comprises a panel, a keyboard is arranged on the panel, at least one key in the keyboard has two switchable functions, and the switching device comprises a gravity sensor and a controller, wherein, the gravity sensor is arranged in the housing and used for sensing the direction of gravity and outputting a gravity signal, and the controller is arranged in the housing, electrically connected with the gravity sensor for receiving the gravity signal and used for judging the direction of the housing according to the gravity signal, outputting a switching signal to the keyboard and leading the key with double functions which is controlled by the control signal to generate the corresponding function switch. The switching device can be used for sensing the direction and the state of the device and automatically switch any one of the two key position functions.

Description

technical field [0001] The invention relates to a hand-held electronic device, in particular to a direction-control key-position double-function key configuration of the hand-held device. Background technique [0002] With the continuous innovation of battery technology and semiconductor technology, various handheld electronic devices are more and more widely used, such as mobile phones, portable multimedia players (PMP, Portable Multimedia Player), remote controllers, MP3 players, personal Digital assistant (Personal Digital Assistant), digital camera, portable global positioning system (Portable Global Positioning System), electronic dictionary (Electronic Dictionary), and auxiliary screen (SideShow) device for Microsoft VISTA operating system, etc. However, it is very complicated and inconvenient for consumers to carry or use a variety of independent handheld devices, so many handheld devices will adopt a two-in-one way to integrate two independent systems into one body, ...

Problems solved by technology

However, it is very complicated and inconvenient for consumers to carry or use a variety of independent handheld devices, so many handheld devices will adopt a two-in-one way to integrate two independent systems into one body, such as the combination of SideShow device and remote control, or mobile Combination of Telephone and PMP

Usually this two-in-one combination performs the operations of the two systems through a shared keyboard, that is, some or all of the keys in the keyboard have two key functions (the first function and the second function), such as a general computer standard keyboard The number keypad on the right side has a second function, and this design can reduce the number of keys, but when using this double-function key, the user must frequently press another control key (usually marked as "second function" (2nd function) Function) or "Transform" (Shift)) to switch the function of the button. Before each operation of the button, the user needs to check whether the button is currently the first function or the second function. If the function needs to be changed, it needs to be switched first. It is extremely inconvenient to use the key to perform the correct function

[0003] At present, there are many two-in-one handheld devices that design the two systems contained in them into two operating modes, such as vertical operation and horizontal operation, such as the two-in-one device of a mobile phone and a video game console (Video Game Console). The phone is designed to be operated upright, and the game console is designed to be operated horizontally. However, there is no two-in-one device on the market that can automatically switch button functions while the body is turning.
