Technical field

The present invention relates to field of mobile communication.The mobile communication equipment of especially hand-holdable operation, such as mobile phone are mobile The bluetooth dialer of phone.This patent is for ease of stating orientation, and one using in mobile phone shell brand identity is as object of reference, mobile phone Upper end refer to mark head institute direction that one end, mobile phone lower end refers to that one end of the mark bottom institute direction; Mobile phone is just setting the state for referring to mobile phone upper end in upper and lower side under, mobile phone inversion refer to mobile phone upper end in lower end in upper shape State;It refers to the state of the head for showing content upward that the content of screen display, which is just being set, and the content inversion of screen display is Refer to the head state directed downwardly of the display content;It is head-up that it refers to font on button that keyboard, which is just being set, and keyboard inversion is The font referred on virtual key is head-down, and the button includes physical button and virtual key;Bidirectional hand described in this patent The two-way function of machine, refers to that mobile phone can screen be operated in lower section above with button for user, and can be for user with button In lower section, two kinds of gripping patterns carry out operating handset to screen above.

Background technology

In the development of mobile phone, divide from its function, three phases can be divided into, first stage is only to communicate substantially The mobile phone of function, this stage is mainly the function of making a phone call and receive and dispatch character message, and mobile phone at this moment is mostly strip , height is generally higher than 12cm, and width is moderate, and human hand is facilitated to hold, and the front plate is provided with display screen and keyboard, and keyboard is set It is placed in below display screen, and the marking keys on keyboard have word of single pullover towards mobile phone upper end;One-handed performance when, palm Mobile phone lower part is held on top, and by thumb press keyboard, and sight falls above thumb the content come shown by viewing screen, screen Except palm.

Second stage is the intelligent machine stage, this stage in addition to basic communication function, also intelligent operating system and its answers The characteristics of with software, (such as Android system, such as the IOS systems of iPhone), two functions are laid equal stress on, mobile phone at this moment is screen Curtain is big (general screen diagonal is between 3 to 6 inches), and fuselage is thin, and front panel is provided with touch display screen, is set in display screen Dummy keyboard is equipped with to replace physical keyboard, dummy keyboard to be located at display screen screen lower part, in addition, some smart mobile phones are touching It touches and is additionally provided with touch key-press below display screen.When one-handed performance, mobile phone lower part is held on the top of palm, by thumb contact keyboard, And sight falls above thumb the content in addition to dummy keyboard come shown by viewing screen, screen is in except palm.

Phase III is the computerized stage, this stage, operating system was sent out to computerization other than basic communication function Exhibition, the time that people are used with it when computer are much more than the time made a phone call with it, to objectively require screen more (screen develops to diagonal line more than 6 inches of directions) greatly.At this moment:On the one hand, hold one 8 inches even 10 inches of mobile end End is very inconvenient very funny to make a phone call, and on the other hand, 10 inches of mobile terminal is placed in satchel, is sent a telegram here When also inconvenient take out at any time answer, thus, just have the tiny bluetooth dialer being conveniently placed in pocket of volume in the market, Couple for carrying out bluetooth with the mobile phone of large screen.Bluetooth dialer has storage communication directory and dialing and answers work( Energy.Bluetooth dialer is strip or is card-shape, all develops to small and thin direction, is taken at any time with facilitating to be placed in pocket With.Height is generally less than palm height, and the front plate is provided with display screen and keyboard, and keyboard is set to below display screen, single When hand operates, mobile phone lower part is held on the top of palm, and by thumb press keyboard, and sight falls and carrys out viewing screen above thumb Shown content, screen dusk is except palm.Since the original volume of bluetooth dialer is with regard to very little, palm can only hold lower half Point, it is seen that the volume very little that can be held is easy to fall.

The above-mentioned phase III, it is mark to be released for the WINDOW10 systems of mobile phone and tablet computer with Microsoft Will, it suffices to say that, just enter this stage currently on the market.

Future trend will have a big chunk young man use:" mobile phone+body of the tablet computer formula of super large screen The situation that this pattern of the bluetooth dialer of product very little ", formation second stage and the mobile phone of phase III are laid equal stress on.

It can be seen that in the prior art, the either mobile phone in that stage, (mobile phone includes that mobile phone or bluetooth are dialled Number device), common feature is, physical keyboard or touch key-press are set to below display screen that (or simulating keyboard is located at touch display The lower part of screen), when one-handed performance, mobile phone lower part is held on the top of palm, and by thumb press keyboard, and sight is fallen above thumb Carry out the content shown by viewing screen, screen dusk is except palm.Such feature results in following defect:

1) it when one-handed performance, mainly can only go to shake hands with palm top half (mainly this two finger of muscle of thenar and index finger middle finger) Machine is unable to fully for the bluetooth dialer of thin stripe type, can only even go to hook with index finger middle finger using the grip of entire palm Firmly it, (referring to Fig. 1) extremely easy to drop；

2) when one-handed performance, because the thumb of palm top half will also be taken into account moves up and down pressing keyboard (including entity back and forth Keyboard or dummy keyboard or touch key-press), it influences muscle of thenar and exerts oneself to mobile phone, be more easy to that mobile phone is caused to fall.Even, for card For the bluetooth dialer of piece type or the touch-screen mobile phone of large screen, mobile phone can only frame on index finger and middle finger, muscle of thenar does not have Grip is applied to mobile phone, is more easy to fall；

3) when one-handed performance, the top half volume of mobile phone is on the top half of palm, that is, is to have majority Mobile phone volume be hanging, mobile phone center of gravity is fallen except palm, and mobile phone is made to be easy to fall key factor, even With the above the 1st and the 2nd point of factor, the three big factors for being unfavorable for mobile phone one-handed performance are constituted.Referred to as, " half palm holds half hand Machine " pattern；

4) when because of one-handed performance, the mobile phone first half is suspended on except palm, i.e., screen is in except palm.(sight is fallen in thumb Carry out the content shown by viewing screen above referring to), the people of your left and right is at this moment stood at one's side or be sitting in, also can very easily see you Content on mobile phone screen is highly detrimental to the privacy that maintains secrecy and protect, and especially following two situations, first is had in crowded In the environment of stranger, such as when taking transit bus and standing subway, in marquis such as queuings, at will sweeps in your bystander and at a glance can See your privacy, it is possible that you also had such experience, be exactly in this case you can see that others is hidden unintentionally It is private；The second situation be when friend classmate meets, everybody sit close sing karaoke together or drink is had a meal, you send out short Letter, the people being substantially sitting in your left and right side and the people that stand, cover all at one glance to your content, you want with another hand It goes masking again too shy, is all classmate kith and kin around Bi Jing, you, which make being undoubtedly across the coverage action opened, is declaring a kind of enemy Meaning can cause others' dislike or even destroy emotion, not cover and cannot protect privacy, be really in a dilemma.

If handset structure is improved to display screen under, button upper, new structure (shielding lower pattern on abbreviation key), Although can solve the above problems, there is also some disadvantages, such as when in the occasion without having to protection privacy, mobile phone user thinks It just cannot achieve in upper button when getting off to operate using customary screen;In another example being used when some users wish to The gripping pattern under key on screen is used when under shielding on key, following one's bent just as wearing the clothes, multiple choices are (as today Mood is liked wearing white trousers depth jacket, and the mood of tomorrow is liked wearing the white jacket of dark trousers again) rather than it is one piece inflexible;In another example right For producer, there are the handset demand of X ten thousand, but the mobile phone for needing traditional structure of how many ratio actually in annual market how much The people of ratio needs keyboard to be also difficult to estimate (this patent, which referred to as classifies it, to be estimated) in cell phone with novel structure of the upper screen under, Compared with a kind of mobile phone of structure is individually produced, it be easy to cause the waste of socialization.

Therefore, anxious in the market to need a mobile phone that meet two kinds of gripping patterns.This patent scheme can be used as two-way The loudspeaker solution of mobile phone.
