Another purpose of the embodiment of the invention is to provide a kind of portable terminal, and described terminal comprises a key control device, and described device comprises an analog switch, and described analog switch connects described button;
Described device also comprises first key-press module that is used for control switch machine button, and second key-press module that is used to control other function buttons;
Described analog switch connects described first key-press module and described second key-press module respectively, and controls the break-make of described first key-press module and described second key-press module respectively.
The embodiment of the invention is by being provided with an analog switch, described analog switch connects the button of described terminal, described analog switch switches the switching that enable signal is controlled first key-press module and described second key-press module according to detected switch from described button, wherein, the described first key-press module control switch machine button, described second key-press module is controlled other function buttons, the present invention has realized the function of switching on and shutting down button and the shared button of other function buttons, and switch very convenient, also improve the portable terminal utilization of space, be beneficial to the popularization of portable terminal.
Description of drawings
The structure chart of the key control device that Fig. 1 provides for the embodiment of the invention;
The structure chart of the analog switch inside that Fig. 2 provides for the embodiment of the invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 1 shows the structure of the key control device that the embodiment of the invention provides.Described device comprises an analog switch 11, first key-press module 12 and second key-press module 13.
Wherein, described first key-press module 12 is used for control switch machine button; Described second key-press module 13 is used to control other function buttons.Preferably, described other function buttons are the key of taking pictures, audio frequency and video play button, and the embodiment of the invention is that example describes with the key of taking pictures.
In specific implementation process, described analog switch 11 connects button, and described analog switch 11 also connects described first key-press module 12 and described second key-press module 13 respectively, and controls the break-make of described first key-press module 12 and described second key-press module 13 respectively.
In specific implementation process, described analog switch 11 is realized the break-make control of described first key-press module 12 with described second key-press module 13 according to the level that detected switch switches enable signal.
Wherein, described device also comprises reserve supply (VBAT) power module 14, and described analog switch 11 connects described VBAT power module 14, powers by the VBAT power supply.
The concrete Fig. 2 that sees also.Fig. 2 is the structure of analog switch inside, the structure of concrete first switch module and second switch module.
The input pin of analog switch, promptly the 4pin pin connects the button of portable terminal;
The output 1pin pin of analog switch connects the key (CAMERA_KEY) of taking pictures, and CAMERA_KEY is used to enter exposal model and takes pictures;
The output 3pin pin of analog switch is as connecting switching on and shutting down buttons (POWER_KEY), and POWER_KEY is used to control the ON/OFF switch;
The 5pin pin of analog switch connects the VBAT power supply, powers by the VBAT power supply;
It is to control by the 6pin pin of analog switch that the output of analog switch is switched.
Wherein, under shutdown mode, the output that analog switch is given tacit consent to the 3rd pin is connected to the input of the 4th pin, and the control 6pin pin of analog switch, and promptly to switch enable signal be low level to switch.When switch switching enable signal was high level, analog switch was output as the 1st pin.
When button was pressed the time threshold values (for example 3 seconds) that is provided with above system, it was low level that switch switches enable signal, and the output that this moment, analog switch was controlled the 3rd pin is connected to the input of the 4th pin, realizes the startup and shutdown function;
