BACKGROUND OF INVENTION 
1. Field of Invention
The present invention relates to a flip-cover mobile phone. More particularly, the present invention relates to a flip-cover mobile phone capable of receiving incoming calls and being operated without lifting up the cover.
2. Description of Related Art
As electronic technology rapidly progresses, mobile phones have become a fast and convenient communication tool to transfer information between people. At present, one common type of mobile telephone has a cover that can flip over to cover the buttons on the phone body. FIGS. 1A and 1B are front views of a conventional flip-cover mobile phone, one having the cover lifted up and the other having the cover flipped back over the main body. As shown in FIGS. 1A and 1B, the flip-cover mobile phone 100 mainly includes a phone body 110 and a flip cover 120. The flip cover 120 is, for example, hinged to the phone body 110 so that the cover 120 may flip over the main body 110 or lift up for normal operation. In general, the flip cover 120 includes a main screen 122, a sub-screen 124 and a loudspeaker 126. The main screen 122 and the loudspeaker 126 are placed on the inner surface of the flip cover 120 while the sub-screen 124 is placed on the outer surface of the cover 120. In addition, the phone body 110 normally has a microphone 112 and a plurality of press buttons 114.
Note that the cover of the flip-cover phone 100 is normally flipped back onto the main body 110 in the standby mode. Therefore, the user must hold the phone in the palm of the hand and lift open the cover before talking on receiving a call. Similarly, the cover 120 must be lifted up to expose the buttons 114 on the main body 110 if the user wants to make a call. Obviously, this is a big inconvenience to the user especially when the user is, say, driving a car. The distraction of lifting up the cover 120 on hearing a phone call may cause accidents.
SUMMARY OF INVENTION 
Accordingly, one object of the present invention is to provide a flip-cover phone with cover-on talking capability so that a user may receive a phone call or operate the phone without lifting up the cover. Ultimately, the phone is more convenient to use and provides less distraction especially while driving a car.
To achieve these and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, the invention provides a mobile phone with cover-on talking capability. The flip-cover phone mainly includes a phone body and a flip cover. The phone body has an inner surface and an outer surface. The inner surface of the phone body has a plurality of keying buttons thereon. Similarly, the flip cover also has an inner surface and an outer surface. The flip cover is hinged to the phone body so that the keying buttons on the inner surface of the phone body can be covered. The outer surface of the flip cover may include a loudspeaker, a microphone and a communication on/off button. In addition, the inner surface of the flip cover may include a first screen and the outer surface of the flip cover may include a second screen. The second screen can be a touch-sensitive screen.
This invention also provides a mobile phone with cover-on talking capability. The mobile phone mainly includes a phone body and a key button cover. The phone body has a plurality of keying buttons. The key button cover is engaged to the phone body through a rotating or sliding mechanism so that the buttons may be hidden behind the cover. A communication on/off button, a loudspeaker and a microphone may be positioned on the surface of the key button cover or the phone body. In addition, the phone body may include a screen within the area covered by the key button cover. The screen can be a touch-sensitive screen.
In this embodiment, a user may press the communication on/off button when the phone rings. Voice signals from the talking terminal will be re-directed to the loudspeaker as soon as the communication on/off button is pressed. In the meantime, the microphone will be activated so that the voice signal from the microphone is transmitted to the talking terminal through a voice processor. Hence, talking may begin without lifting up the flip cover.
If the user needs to operate the mobile phone without lifting the flip cover, one may do so through the touch sensitive screen and execute those instructions by pressing the communication on/off button.
The communication on/off button may even be eliminated if the on/off button is functionally integrated with the touch sensitive screen. Hence, the phone may start to execute the key-in instructions once a region on the touch sensitive screen is touched.
Furthermore, if the user just wants a mobile phone with cover-on talking capability and has no regards for cover-on operating capability, the communication on/off button may be retained and a normal screen instead of a touch sensitive screen may be used to lower production cost.
It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed.

DETAILED DESCRIPTION 
Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
FIGS. 2A and 2B are front views of a flip-cover mobile phone according to one preferred embodiment of this invention, one having the cover lifted up and the other having the cover flipped back over the main body. In this embodiment, the flip-cover mobile phone 200 mainly includes a phone body 210 and a flip cover 220. The phone body 210 has an inner surface 212 and an outer surface 214. The flip cover 220 also has an inner surface 222 and an outer surface 224. The flip cover 220 is hinged onto the phone body 210 so that the cover 220 is free to flip open or close. The cover 220 also has a screen 226 (main screen) and a loudspeaker 230 on the inner surface 222 and another screen 228 (a sub-screen) on the outer surface 224. The inner surface 212 of the phone body 210 has a microphone 216 and a plurality of buttons 218 thereon. Since the cover 220 is hinged to the phone body 210, the inner surface 222 of the cover 220 is able to touch the inner surface 212 of the phone body 210. Hence, the buttons 218 on the inner surface 212 can be hidden inside the mobile phone 220.
Note that the outer surface 224 of the cover 220 may further include a loudspeaker 232, a microphone 234 and a communication on/off button 236. Furthermore, the loudspeaker 232 and the microphone 234 may function interchangeably with the aforementioned loudspeaker 230 and the microphone 216.
FIG. 2C is a flow chart showing the steps for talking to the cover-on talking flip-cover mobile phone according to this invention. As shown in FIGS. 2B and 2C, in the standby mode (with the cover over the phone body), the communication on/off button 236 on the flip cover 220 is checked to see if it is pressed when the phone 200 rings. If no one presses the communication on/off button 236, the ringing continues. Otherwise, if the communication on/off button 236 is pressed, the talking terminal picks up audio signals from the caller so that the communication on/off button 236 is switched to the loudspeaker 232. In the meantime, the microphone 234 on the cover 220 is triggered so that the voice signals received by the microphone 234 are transmitted to an audio processor. After processing, the voice signal is sent to the talking terminal, thereby fulfilling cover-on phone receiving. After the talking is over, the communication on/off button 236 is again pushed to return the phone to the standby mode. In other words, one press of the communication on/off button 236 enables a user to receive an incoming call and another press on the on/off button 236 to end a talking session. Hence, the user is free from too much distraction, especially when driving a car.
In addition, the screen 224 on the outer surface 224 of the flip cover 220 can be a touch sensitive screen. The touch screen is an information exchange interface tool having a variety of specially designed icons for selection. When one of the icons is selected through touching the screen, another picture may appear on the screen so that the required information is displayed. Hence, by using touch-screen technologies, a user may operate the mobile phone without flipping open the cover.
FIG. 2D is a flow chart showing the steps for operating the cover-on talking flip-cover mobile phone according to this invention. As shown in FIGS. 2B and 2D, in the standby mode (without lifting the cover), the touch screen is used as an interface with the phone. For example, the touch screen can be used to find data or dial a telephone number. An instruction, which is a confirmation instruction, is executed when the communication on/off button 236 is pressed. Using phone dialing as an operating example, a finger may be used to touch one of the items on a preset phone book so that the required data is recalled. If the recalled data matches the desired dial-up number, the communication on/off button 236 is pressed to dial up the number. In other words, the mobile phone may operate with the cover on the phone body. However, if the recalled data is not the correct number, the touch screen may be triggered by touch to scroll down and display more data so that the user may be able to find a matching number.
Furthermore, the communication on/off button 236 may be functionally integrated with the touch screen so that the communication on/off button 236 is physically removed from the phone. In this case, a confirmation icon may appear on the touch screen. Once the desired dialing number is found, the dialing instruction is executed by dialing the number with a single touch of the confirmation button. Hence, cover-on operation of the mobile phone is attained.
In some situations such as driving, a user needs to receive phone calls much more frequently than dialing. If this is the case, some cost for producing the phone 200 may be saved by retaining the communication on/off button 236 while replacing the touch screen with an ordinary screen.
