Embodiment
Below in conjunction with an embodiment shown in the drawings the portable terminal that possesses scroll earphone of the present invention is elaborated.
Fig. 3 possesses in the portable terminal of scroll earphone the back view to the spool part for the present invention; Fig. 4 is the decomposing schematic representation of scroll earphone of the present invention; Fig. 5 is the assembling section of scroll earphone of the present invention; Fig. 6 is the block of scroll earphone of the present invention and the enlarged drawing of the corresponding states of the anti-stops of rotation; The operate condition profile of block and the anti-stops of rotation when Fig. 7 a and Fig. 7 b untie earphone for scroll earphone of the present invention; The operate condition profile of Fig. 8 a and Fig. 8 b scroll earphone during for scroll earphone rollback earphone of the present invention.
As shown in the figure, the portable terminal that possesses scroll earphone of the present invention comprise terminal fuselage 10 be built in the terminal fuselage and can extract out, be connected with fuselage 10 and export the scroll earphone 20 of auditory information.
Terminal fuselage 10 possesses the bottom that can rotate combination mutually and renovates the battery B that renovates (not shown) with top and be combined in the bottom flip back surface.
Scroll earphone 20 has certain inner space, is made up of protecgulum 21, bonnet 22, earphone 23, a plurality of spool 24, helical spring 25 and block 26.Protecgulum 21 and bonnet 22 are arranged on the inside of above-mentioned terminal fuselage 10; Earphone 23 can be built in the inner space of above-mentioned cap 21,22 with extracting out in terminal fuselage 10, it exports the auditory information that above-mentioned terminal fuselage provides; A plurality of spools 24 possess coil (cord) 23b at above-mentioned terminal fuselage rollback earphone 23; Helical spring 25 drives said reel 24, and the coil 23b of earphone 23 is drawn in around said reel 24; Block 26 fixing said reel 24 when extracting earphone 23 out makes its earphone 23 coil 23b keep the extraction state.
Protecgulum 21 as shown in Figure 4, form to have the drum that seals, its central authorities of sealing the side form button hole 21a and make coil described later twine button 28 to be exposed on the external, and the both sides of inner peripheral surface are with height and width outstanding the form rotation anti-stops 21b overlapping with above-mentioned block 26.The anti-stops 21b of rotation is advisable for the extraction sectionalization that can make earphone 23 forms more than two.
Earphone 23 is exported the unit 23a of auditory information and is positioned at the side of unit 23a and prolongs coil (cord) 23b that the one end makes the main printed circuit board of its connecting terminal fuselage 10 and form as shown in Figure 3 and Figure 4 by having jolting plate in inside.
Coil 23b forms and is wrapped on each spool 24 with single line as shown in the figure, is wrapped on the spool 24 but also can be made up of multiple line.
Spool 24 as shown in Figure 4 and Figure 5, the rotating shaft of putting with the Width of fuselage 10 row is the rotatable combination in center, the center of each spool 24 makes its spinning reel 24 so that coil 23b rollback respectively is provided with above-mentioned helical spring 25 to spool 24 direction on every side.
One side outer peripheral face of spool 24 is provided with to prevent that with above-mentioned rotation the overlapping height and the width of stops 21b resist a plurality of blocks 26 of helical spring elasticity direction.
Block 26 is made up of rotatable body 26a and the anti-stops 26b of winding as Fig. 4 and shown in Figure 6.Rotatable body 26a forms with the height that is overlapped in the anti-stops 21b of rotation, and makes it cross the anti-stops 21b of its rotation with elastic material formation; Twining anti-stops 26b forms with the height that is not overlapped in the anti-stops 21b of rotation in the side of rotatable body 26a, and, form with the rigidity material identical with the material that forms spool 24 for making above-mentioned rotatable body 26a resist the direction of rotation (winding direction) of any side.
Rotatable body 26a is bent to form the corner angle of untiing coil 23b direction in the corner angle in the top as shown in Figure 6, and it is suitable that the corner angle of the anti-stops 21b of the rotation corresponding with it also make it be bent into, thereby rotatable body 26a can cross the anti-stops 21b of rotation smoothly.
The anti-stops 21b of block 26 and rotation is removing under the situation that the external force effect is arranged to making it overlapping with circumferencial direction, and be that spool supports that spring gives the elastic force support with direction of principal axis then between the bonnet 22 to the compression spring, coil winding button 28 is pushed said reel 24 open when rollback coil 23b makes block 26 exceed the direction of principal axis scope of the anti-stops 21b of rotation, and it supports that at said reel tossing about of spring 27 is integrally formed with spool.The formation that coil twines button 28 is advisable its outside that is exposed at terminal fuselage 10.
Undeclared part 22a is that coil passes through groove in the accompanying drawing.
The aforesaid terminal that possesses scroll earphone of the present invention has following action effect.
That is, spool 24 is rotated and extracts out coil 23b when stretching backguy circle 23b and extract earphone 23 out.At this moment, shown in Fig. 8 a, spool 24 is pushed open by spool support spring 27 and is rotated, the rotatable body 26a of block 26 also rotates and touches the anti-stops 21b of rotation of protecgulum 21 together, but shown in Fig. 7 a, direction (the helical spring elasticity direction) free bend that the rotatable body 26a of block 26 extracts out with coil, therefore, rotatable body 26a crosses the anti-stops 21b of above-mentioned rotation, and spool 24 is rotated smoothly.When coil 23b is stretched to the pulling force of certain-length releasing earphone 23 in this process, shown in Fig. 7 b, spool 24 because of the elastic force (restoring force) of helical spring 25 with contrary direction rollback certain-length and when the rotatable body 26a of block 26 is suspended to the anti-stops 21b of rotation, its rotatable body 26a can not be prevented stops 26b bending by the winding of rigid body, thereby spool 24 stops the rotation.
In addition, in order to finish under the state of earphone 23 to use and rollback earphone again extracting out, should make above-mentioned block 26 break away from the anti-stops 21b of rotation.For this reason, the user is twined button 28 by lower coil, spool 24 is shown in Fig. 8 b, overcoming spool supports the elastic force of spring 27 to turn right to move the direction of principal axis scope that makes above-mentioned block 26 exceed the anti-stops 21b of rotation, meanwhile, spool 24 is rotated because of the restoring force of its inner helical spring 25 and the coil 23b of earphone 23 is drawn in the peripheral direction rollback.
Before address in the illustrated embodiment, be that example describes to possess the so-called flip-type portable terminal that renovate on the top that can rotate combination mutually and renovate the bottom, also be natural but the present invention is applicable to so-called cover type or board-type portable terminal.
According to the portable terminal that possesses scroll earphone of the present invention, utilize the spool that can rotate freely when extracting earphone out, utilize the contrary direction rotation of block selectivity restriction simultaneously, therefore can stretch the length of drawing earphone according to demand easily, and after using, draw the one touch in keeping, thereby improved the convenience that uses.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
