Specific implementation mode
The technical solution of the utility model is described in further detail with reference to the accompanying drawings and detailed description.
Referring to figs. 1 to Fig. 5, the present embodiment line control earphone control box, including upper casing 100, lower casing 200 and button 300, upper casing
100 and lower casing 200 surround control box cavity 400, upper casing 100 is equipped with key hole 110, and button 300 includes 310 He of key main body
The conductive switch shrapnel 320 being correspondingly arranged with key main body 310（It is dome pieces in the present embodiment, in order to further enhance button
Durability, conductive switch shrapnel 320 can be that PCB surface reveals copper, and conductive carbon granules is pasted below key main body 310）, press
Key main body 310 is mounted on upper casing 100 in a pressing way, is particularly located in key hole 110；Button 300 further includes in the present embodiment
Cursor 330 in control box cavity 400 and elastic component 340, cursor 330 are rotatably connected to the interior of upper casing 100
On surface 120；One end of cursor 330 is pivotally connected key main body 310 and the end is located at key main body 310 and conductive switch shrapnel
Between 320, the other end of cursor 330 is resisted against along the telescopic direction of elastic component 340 in the first end 341 of elastic component 340, bullet
The second end 342 of property part 340 is resisted against on the inner surface 120 of upper casing 100.For convenience of description, in the present embodiment, for cursor
The one end being articulated with key main body 310 on 330 is known as its pivot end 331, with elastic component 340 against the other end be known as it and support
By end 332.
As depicted in figs. 1 and 2, cursor 330 forms lever construction, one end（That is pivot end 331）It is cut with scissors with key main body 310
It connects, the other end（That is abutment end 332）It is resisted against in the first end 341 of elastic component 340.Under non-triggering conditions, the bullet of elastic component 340
Power can jack up downwards the abutment end 332 of cursor 330, and the pivot end 331 of cursor 330 is made to lift, and then jack up key main body
310, conductive switch shrapnel 320 is not touched；When pressing keys main body 310, key main body 310 moves downward, and touches conduction
Switch shrapnel 320 is completed to connect；It is completed when key main body 310 acts, the elastic force of elastic component 340 jacks up cursor 330 again,
Cursor 330 and key main body 310 is set to restore non-triggering conditions.Then the reset of key main body 310 is by rotating in the present embodiment
The mechanical resetting structure that arm 330 and elastic component 340 form is realized, is adjusted and is buffered it is not necessary that silicagel pad is arranged, due to no silicon
Rubber cushion, then so that button whole service life is long；Meanwhile passing through the elastic force of elastic component 340 so that conductive switch shrapnel 320
Elastic force is controllable；In addition, key main body 310 makes key main body 340 be detached from pressure in non-pressed state due to the elastic force of elastic component 340
Compel conductive switch shrapnel 320, avoids conductive switch shrapnel 320 from bearing useless touching power, substantially prolong its service life.
For the pivot joint between the pivot end 331 and key main body 310 of cursor 330, in cursor 330 in the present embodiment
Pivot end 331 on be fixed with cylindrical drive-connecting shaft 333, as shown in Figures 1 to 5, correspondingly, be equipped in key main body 310
Mounting groove 311 compatible with the pivot end 331 of cursor 330 and cylindrical drive-connecting shaft 333, cylindrical drive-connecting shaft 333 are caught in
To realize the pivot joint of the pivot end 331 and key main body 310 of cursor 330 in mounting groove 311.Meanwhile cylindrical drive-connecting shaft 333
For cylinder, the matched position of mounting groove 311 is also arc-shaped, then it is smooth to may insure that cursor 330 rotates, in turn
Key main body 310 is set to act smooth.
Further, as shown in figure 3, cylindrical drive-connecting shaft 333 includes cylindrical body portion 3331 and is installed in cylinder
Cylindrical holding section 3332 in 3331 both ends of the surface of main part, cylindrical holding section 3332 are coaxially set with cylindrical body portion 3331
It sets, i.e., axis overlaps, and the diameter of cylindrical holding section 3332 is less than cylindrical body portion 3331.Accordingly, as shown in figure 4,
Position compatible with cylindrical drive-connecting shaft 333 adds the structure of both ends sulculus, cylinder-shaped body in intermediate large trough on mounting groove 311
Portion 3331 is embedded in intermediate large trough, and arc-shaped holding section 3222 is caught in the sulculus of end.Using the cylinder of this structure type
Shape drive-connecting shaft 333 and mounting groove 311, on the basis of ensureing that cursor 330 rotates smooth, the arc-shaped holding section of minor diameter
3222 can easily be caught in the end sulculus of mounting groove 311, in order to the connection of cursor 330 and key main body 310.
To improve the reliability that cursor 330 is pivotally connected with key main body 310, mounting groove 311 is interior to be equipped with position limiting structure 312,
To prevent cylindrical drive-connecting shaft 333 to be detached from mounting groove 311.
Further, position limiting structure 312 is the limit rib being correspondingly arranged with cylindrical holding section 3222, passes through arc-shaped card
Conjunction portion 3222 coordinates with position limiting structure 312, since cylindrical holding section 3222 is small compared with 3331 diameter of cylindrical body portion, is convenient for it
It squeezes into end sulculus of the mounting groove 311 with position limiting structure 312.
Connection for cursor 330 and upper casing 100, specifically, as shown in figure 5, on the inner surface 120 of upper casing 100
It is installed with holder 130, holder 130 carries through-hole 131, through-hole 334 is accordingly arranged on cursor 330, cursor 330 is by a shaft
350 are rotatably connected to the through-hole 334 on cursor 330 and the through-hole 131 on holder 130 on holder 130.Certainly, two
Other modes that are rotatably connected also can be selected in person, and the present embodiment is not particularly limited this.
As shown in figure 3, the abutment end 332 of cursor 330 is equipped with the first storage tank 335 and is located at the first storage tank 335
The first interior pillar 336, the first end 341 of elastic component 340 is embedded in 335 interior and elastic component 340 first end 341 of the first storage tank
It is set on the first pillar 336.First storage tank 335 plays positioning action to elastic component 340, and the first pillar 336 is used for being oriented to
Elastic component 340 prevents elastic component 340 from being deviated in telescopic process, improves 330 Reliability of Microprocessor of cursor.
Similarly, as shown in figure 5, in combination with shown in Fig. 2, the second storage tank is equipped on the inner surface 120 of upper casing 100
140 and the second pillar 150 in the second storage tank 140, the second end 342 of elastic component 340 is in the second storage tank 140
And the second end 342 of elastic component 340 is set on the second pillar 150.
The elastic component of 340 preferred metal material of elastic component, such as spring or shrapnel, shape and stable mechanical performance, can hold
Loaded and aximal deformation value makes key main body 310 reset smooth, reliable in action, further increases its service life.
The present embodiment also proposed a kind of line control earphone, including control box, and the concrete structure of control box is new referring to this practicality
The embodiment and attached drawing 1 of molded line control earphone control box are to the description of Fig. 5, and details are not described herein.
Above example is only to illustrate the technical solution of the utility model, rather than is limited；Although with reference to before
Embodiment is stated the utility model is described in detail, it for those of ordinary skill in the art, still can be right
Technical solution recorded in previous embodiment is modified or equivalent replacement of some of the technical features；And these
Modifications or substitutions, the utility model technical solution claimed that it does not separate the essence of the corresponding technical solution spirit and
Range.
