Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation, it is therefore an objective to those skilled in the art be helped to have more complete, accurate and deep reason to design of the invention, technical solution
Solution, and facilitate its implementation.
From the angle analysis of human engineering, optimal earphone jack position should be located at one end of the bottom of mobile phone, use in this way
When earphone is listened at family earphone cable move towards it is smooth be not in wide-angle turnover, and because the charging interface of current mobile phone also is located at hand
The bottom of machine, when listening earphone in charging, charging cable and earphone cable are stretched out from one side, and cabling is very clean and tidy easy to carry.
It introduces in detail below,
As shown in Fig. 2, cell-phone cover 2 is the set protected in the prior art to mobile phone bottom surface and four sides, this set
It can also be with the flip lid to screen protection.
As shown in Figure 1 and Figure 5, the top of mobile phone 1 is equipped with the first earpiece holes 11, and the Position Design of the first earpiece holes 11 does not conform to
Comprehend occur cabling have some setbacks, wire rod frangibility and not readily portable problem.The present invention designs built-up circuit 3 for the first earphone
Hole 11 is electrically connected with the second earpiece holes 21 of 2 bottom of cell-phone cover.
As shown in Fig. 2, the first plug 31 is Fourth Ring headset plug, diameter is selected according to the mobile phone model that cell-phone cover is applicable in
2.5mm 3.5mm specification.33 side of circuit board is arranged 4 contacts, contact preferably axially flexible contact, increases and the
Two plugs, 4 contact reliability.Conducting wire 32 is made of four electric wires insulated from each other, and 32 electrical connection circuit plate 33 and first of conducting wire is inserted
First 31 corresponding conducting ring, wherein the first contact 331 is only electrically connected with the first ring 311 by conducting wire 32；Second contact 332 passes through
Conducting wire 32 is only electrically connected with the second ring 312；Third contact 333 is only electrically connected with third ring 313 by conducting wire 32；4th contact
334 are only electrically connected with Fourth Ring 314 by conducting wire 32.It is conductive after second plug 4 is inserted into the second earpiece holes 21 of cell-phone cover 2
Ring is contacted with the contact on circuit board 33 respectively, wherein the first ring 41 is only contacted with the first contact 331；Second ring 42 is only with second
Contact 332 contacts；Third ring 43 is only contacted with third contact 333；Fourth Ring 44 is only contacted with the 4th contact 334.It is equivalent to
Each contact of two plugs 4 and the first plug 31 is one-to-one, and the first plug 31 is inserted into the first earpiece holes 11 of mobile phone 1
In with inside mobile phone 1 circuit foundation be electrically connected, i.e., the second plug 4 is established with mobile phone 1 is electrically connected.
As shown in Fig. 3, Fig. 7 and Fig. 8, cell-phone cover 2 is made of soft material, such as rubber, silica gel, and the first plug 31 is located at
The position of first earpiece holes 11, the first plug 31 one end and cell-phone cover 2 far from insertion end part are connected, the bottom of cell-phone cover 2
Equipped with second earpiece holes 21, the second earpiece holes 21 are a flat blind holes, and the side wall of blind hole is equipped with one and opens along axial direction
If elongated slot, four contacts on such circuit board 33 are located at the inside in hole after stretching out in elongated slot.
As shown in Figures 3 to 6, the second earpiece holes 21 are located at one end of mobile phone bottom, and the second earpiece holes 21 are a flat
Blind hole, nature opened gap less than 4 conducting ring of the second plug diameter, since the second earpiece holes and cell-phone cover 2 are one
Body formed, material is identical, be it is flexible, when the second plug 4 is inserted into the second earpiece holes 21, the second earpiece holes 21 are softened
The second plug 4 is tightly clamped, realizes reliable connection.The design of this elastic opening so that cell-phone cover 2 volume here
What can be done is smaller, realizes compact design.
Conducting wire 32 be it is flat be tightly attached to 2 inner wall of protective case, conducting wire 32 is between mobile phone 1 and cell-phone cover 2, in order to prevent
Cell-phone cover 2 is by the jack-up of conducting wire 32, out-of-flatness, inside deep gouge of the part of the cell-phone cover 2 contacted with conducting wire 32 to cell-phone cover 2, slot
Depth be not less than conducting wire 32 thickness.
As shown in Figure 8 and Figure 9, behind the position of the second plug 4 insertion preset second earpiece holes 21 of cell-phone cover 2, cabling is suitable
Freely, wire rod be not easily broken with it is easy to carry.
Key in order to solve the problems, such as mobile phone continues to improve commonly using being easily damaged in built-up circuit 3.
As shown in Figure 10,4 conducting ring headset plugs have and only there are two types of standards, and the difference of both standards is only that the first ring 41 and the
Two rings 42 definition microphone (MIC+) and signal circuit (GND) be it is reverse, (i.e. first between the first ring 41 and the second ring 42
Between ring 311 and the second ring 312) one normal open switch of connection, in this way when user touches this switch, mobile phone 1 will be detected
Resistance value mutation between first ring 41 and the second ring 42, in this way in conjunction with the application program of the prior art to the letter of this change in resistance
It number is detected, realization spreads its tail, screen locking or directly opens application program, avoids so frequently to mobile phone key
Operation, avoids the damage of mobile phone key.In order to reliably fix normal open switch, this normal open switch is designed first
End face of the plug 31 far from insertion end, i.e. Figure 11 pointed location, touch end face, are the operations for being highly convenient for user.
These are only the preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
