Description

Mobile terminal

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone, and more particularly, to a mobile phone that is suitable for a user to conveniently use various functions of an image, sound, and vibration output through a mobile phone.

With the development of wireless communication technology, the use cost of mobile phone is increasing and the call quality is also improved to make high quality call even in a driving vehicle.

The basic configuration of a mobile phone is an antenna for transmitting and receiving wireless signals between a base station and a mobile phone, a speaker for allowing a user to listen to a voice signal, a microphone for receiving a user's voice, and a function button for pressing another phone's phone number or inputting data. Keypad unit, a display unit on which a dialed telephone number or a character indicating the function setting or status of the current mobile terminal is displayed, a flip to protect the keypad, and data for transmitting and receiving data Earphone connection unit for connecting the transceiver and the earphone.

In the call method of the mobile phone having such a configuration, when the number of the called party to be called is manipulated on the keypad of the mobile terminal, the called party number is displayed on the display unit, and when it is determined that the display state of the display unit is correct, the user calls. Pressing Send sends a call to the other party. When the call is connected with the other party, the call is made using the microphone and speaker which are voice input / output units configured in the mobile phone.

In general, a mobile phone is a bar-shaped, elongated bar, a flip-type like a lid attached to a bar-shaped keypad, and a liquid crystal display (LCD) part of a terminal and a key pad part. There is a clamshell.

A liquid crystal display (LCD) is used as a display unit of the mobile phone, and the display unit displays characters or pictures so that the user can see the current state of the mobile phone or various information provided by the mobile phone.

In such a mobile phone, it is exposed to the outside of the mobile phone such as driving a speaker or receiver, driving a buzzer (or ringer), driving a display unit, or driving a vibrator. Control of the working components is generally in a software manner.

That is, a general mobile phone operation method is to control the sound of the receiver on / off or to turn on / off the buzzer by operating the menu or the set up keypad while looking at the display unit while the mobile phone is turned on. It turned off, the display conditions of the display part were adjusted, or the vibrator was driven.

For example, a method of operating a buzzer that generates a sound when an incoming call is received by a mobile phone is that a user presses the 'Menu' or 'Setting' key while watching the display of the mobile phone while the mobile phone is turned on.

The mobile phone display unit then displays a menu such as '1: volume control', '2' selects a telephone ring, '3' is selected, '8: additional functions', and the like.

At this time, when the user presses '1' on the keypad of the cellular phone, a menu such as '1: telephone ring volume, 2: key tone volume, and 3: call volume' is displayed on the display unit of the cellular phone.

When the mobile phone user presses '1' on the keypad, the display of the mobile phone displays the current ringing tone as 'picture' along with the text 'telephone ring' and 'weak middle'.

Then, the user manipulates the arrow-shaped search keypad to select the strength of the 'phone ring' of the mobile phone, either 'weak, medium, or strong', or 'no sound' mode, which is a mode of no sound at all. Finally, pressing the 'Save' key saves the current state in the phone's memory while the phone's buzzer operates in one of the following modes: weak, medium, strong or mute.

And, the volume of the call using the mobile phone is output through the speaker, the speaker sound can also be adjusted using the method as described above. In this case, the reason for adjusting the volume of the speaker is that when the other party's voice is loud during a call, not only the user of the mobile phone but also the neighbors can hear the situation.

The vibrator of the mobile phone is a device that can be used conveniently to solve the problem of telephone ring noise, which is recently seriously troubled. Also, the vibrator of the mobile phone is used on and off depending on the situation. Use the operation.

And the display unit of the mobile phone can be divided into two.

The first is operation related to the backlight of the display unit, and the second is on / off of the display unit.

In general, the backlight of the display unit is not a problem when the mobile phone is used during the day, but when used at night, the on-time of the backlight of the display unit should be long.

Therefore, when the user wants to use the mobile phone at night, the backlight of the display unit should always be on while the flip or folder type mobile phone is opened while the flip or folder is open. The operation of the display unit of the mobile phone is also controlled using a software method as in the operation of the buzzer described above.

In addition, recently, a mobile phone with the addition of a speaker phone function is sometimes released. Such a method of operating the speaker phone is also achieved through a software method as described above.

In such a conventional mobile phone, since the method for adjusting the sound, video, and vibration functions output through the mobile phone is configured in software, there are problems that require a plurality of operation processes to select a single function, in particular, a speaker, a buzzer, In the case of vibration, it is often necessary to operate quickly depending on the situation. However, the operation process is performed in such a way that the user must operate while watching the display of the mobile phone, so that it is not easy for the user to operate urgently. In addition, people with disabilities may feel uncomfortable in various stages of operation, and in particular, there is a problem that even if the operation alone is impossible, such as in the case of the visually impaired.

An object of the present invention has been made in view of the above-mentioned problems of the prior art, to provide a mobile phone that increases the user's convenience by enabling the operation of the components exposed to the outside of the mobile phone to operate using a switch. It is to.

According to a feature of the present invention for achieving the above object, a display device for displaying an image or a character under the control of the central processing unit, and an incoming signal generator for generating an incoming signal connected to the audio amplifier or vibration device; And a switching switch for controlling a selection signal from the central processing unit to the display device or for controlling the operation of the incoming signal device.

According to the present invention as described above, it is possible to simply configure the typical functions of the mobile phone, there is an advantage that the use of the disabled as well as general users, in particular, including the visually impaired.
