Spring rolling wheel mechanism center is located on the cylinder (12) of main frame (1) casing inner wall protrusion; Cylinder (12) outside coiling a few coil spring sheets (61), spring leaf (a 61) outside circle wheel of cover (62), spring leaf (61) one ends are fixed on the cylinder (12), the other end is fixed on circle wheel (62) inboard, circle wheel (62) but outer felt around pull on line (8) tens circles, both sides are folded by the circle wheel wheel wing (63), make unlikely the coming off of on line (8), one circle pawl (64) is installed in the circle wheel wheel wing (63) outside, on put a card article (65), card article (65) other end links to each other with a wheel button (7) of main frame (1) casing side, is used for blocking the circle wheel wheel wing (63), the reversing of control rolling wheel
But pull on line (8) inner conductors is electrically connected external microphone (2) and external earphone (3) simultaneously with hand-set host.
The earphone microphone on line will have stronger tensile strength, and shape can be flat, 1 millimeters thick, 2 mm wides, length can be decided to be about 1 meter according to human arm mean value, it with circle size of wheel relation as shown in the formula:
Wherein: L is an on line length
D1 is the circle wheel diameter
D2 is wheel wing diameter
D is an on line thickness
If can calculate the circle wheel diameter is 20 millimeters, wheel wing diameter is 33 millimeters, adopting above-mentioned thickness is 1 millimeter on line, 12～13 circles of reeling can reach 1 meter left and right sides length, at this moment circle wheel thickness gauge be 2 millimeters more, if thickness is increased, line length also can correspondingly increase, or keeping under the identical line length situation, the diameter of the circle wheel and the wheel wing can be done forr a short time.
According to Theory of Electromagnetic Field as can be known, square being inversely proportional to of electromagnetic radiation intensity and distance is during the regular handset conversation, antenna is from 4 centimeters of brain distances, if using above-mentioned on line is 1 meter external earphone and microphone, it is original 1/625 that the suffered radiation intensity of brain is dropped to, and promptly lowered more than the 23dB
Use principle is as follows: when needing to use built-in external microphone and earphone, only need rigidity rod tube (4) is taken out in main frame (1) casing groove (11), touch-pressure switch (K) resets, original loud speaker (9) and pick-up (10) are disconnected in the mobile phone, and external earphone (3) on the rigidity rod tube (4) and microphone (2) are coupled, carry out normal talking, along with on line (8) during by pull, reed (61) rotation of moving of circle wheel (62) rotating band forms reactive torque, make on line (8) produce retraction tension force, when moving correct position to, decontrol on line, card article (65) falls naturally, block the pawl (64) on the circle wheel wheel wing (63), circle wheel (62) can not be turned round, thereby eliminated the retraction tension force of on line (8), so that conversation is convenient, do not need handheld mobile phone, after rigidity rod tube convex protrusion body (41) filled in helix, the galianconism end (42) of L type was pressed close to the corners of the mouth naturally and can be conversed, and after finishing rigidity rod tube (4) is taken off from the helix position, click back wheel button (7) again, restore the card key.Reactive torque discharges, circle wheel (62) revolution, on line (8) is recovered to hand-set host (1) inside, rigidity rod tube (4) blocks back again in main frame (1) the casing groove (11), touch-pressure switch (K) is backed down, original loud speaker of mobile phone (9) and pick-up (10) are connected, and can be same as again to use regular handset to converse.
