Specific embodiment

Below against accompanying drawing, by the description to embodiment, specific embodiment of the present utility model is made further in detail Thin explanation, it is therefore an objective to help those skilled in the art design of the present utility model, technical scheme are had it is more complete, accurately and Deep understanding, and contribute to its enforcement.

From the angle analysis of human engineering, optimum earphone jack position should be located at one end of the bottom of mobile phone, so use When earphone is listened at family earphone cord move towards it is smooth be not in wide-angle turnover, and because the charging inlet of current mobile phone also is located at handss The bottom of machine, when listening earphone in charging, charging wire and earphone cord are stretched out from one side, and cabling is neatly easy to carry very much.

Introduce in detail below,

As shown in Fig. 2 cell-phone cover 2 is the set protected to mobile phone bottom surface and four sides in prior art, this set Can also be with renovating to screen protection.

As shown in Figure 1 and Figure 5, the top of mobile phone 1 is provided 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.This utility model designs built-up circuit 3 by first Earpiece holes 11 are 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 suitable for 2.5mm or 3.5mm specifications.33 side of circuit board arranges 4 contacts, and contact preferably axially resilient contact increases and inserts 4 contact reliabilities.Wire 32 is made up of four electric wires insulated from each other, 32 electrical connection circuit plate 33 of wire and the first plug 31 Corresponding conducting ring, wherein the first contact 331 is only electrically connected with the first ring 311 by wire 32；Second contact 332 passes through wire 32 are only electrically connected with the second ring 312；3rd contact 333 is only electrically connected with the 3rd ring 313 by wire 32；4th contact 334 leads to Cross wire 32 only to electrically connect with Fourth Ring 314.Plug 4 insertion cell-phone cover 2 the second earpiece holes 21 after, its conducting ring respectively with electricity Contact on road plate 33, wherein the first ring 41 is only contacted with the first contact 331；Second ring 42 is only connect with the second contact 332 Touch；3rd ring 43 is only contacted with the 3rd contact 333；Fourth Ring 44 is only contacted with the 4th contact 334.Equivalent to plug 4 and first Each contact of plug 31 be it is one-to-one, and the first plug 31 insertion mobile phone 1 the first earpiece holes 11 in mobile phone 1 inside Circuit set up electrical connection, i.e., plug 4 is established with mobile phone 1 and is electrically connected.

As shown in Fig. 3, Fig. 7 and Fig. 8, cell-phone cover 2 is made up of soft material, such as rubber, silica gel etc., and the first plug 31 is located at The position of the first earpiece holes 11, the first plug 31 are connected with cell-phone cover 2 away from one end of insertion end part, the bottom of cell-phone cover 2 It is provided with second earpiece holes 21, the second earpiece holes 21 are the blind holes of a flat, the side wall of blind hole is provided with one and opens vertically If elongated slot, four on such circuit board 33 stretch out from elongated slot contact after be located at hole inside.

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, diameter of the naturalness opened gap less than 4 conducting ring of plug, due to the second earpiece holes and cell-phone cover 2 be one into Type, material is identical, is resilient, and when plug 4 inserts the second earpiece holes 21, the second earpiece holes 21 are softened tightly to clamp Plug 4, realizes reliable connection.It is less that the design of this elastic opening allows that the volume herein of cell-phone cover 2 does, Realize compact design.

Wire 32 be it is flat be close to 2 inwall of cell-phone cover, wire 32 is located between mobile phone 1 and cell-phone cover 2, in order to prevent Cell-phone cover 2 by 32 jack-up of wire, out-of-flatness, the inside deep gouge of the part of the cell-phone cover 2 contacted with wire 32 to cell-phone cover 2, groove Depth not less than wire 32 thickness.

As shown in Figure 8 and Figure 9, behind the position of the insertion of plug 42 default second earpiece holes 21 of cell-phone cover, cabling is smooth, line Material is not easily broken and is easy to carry.

It is easily damaged in order to the button for solving the problems, such as mobile phone is commonly used, proceeds to improve in built-up circuit 3. As shown in Figure 10,4 conducting ring headset plugs have and only two kinds standards, and the difference of both standards is only that the first ring 41 and The mike (MIC+) and signal circuit (GND) of the definition of bicyclo- 42 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, so when user touches this switch, mobile phone 1 will be detected Resistance mutation between first ring 41 and the second ring 42, so combines letter of the application program of prior art to this change in resistance Number detected, realization is spread its tail, screen locking or directly open application program, so avoids frequently to mobile phone button Operation, it is to avoid the damage of mobile phone button.For reliable fixed normal open switch, this normal open switch is designed first End face of the plug 31 away from insertion end, i.e. Figure 11 pointed locations, touch to end face, are the operations for being highly convenient for user.

Preferred embodiment of the present utility model is these are only, this utility model is not limited to, for this area Technical staff for, this utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle within, Any modification, equivalent substitution and improvements made etc., should be included within protection domain of the present utility model.
