Abstract
A kind of earmuff automatic reset structure of earphone, head hoop is connected with supporting bracket with the backstay on earmuff by being fixedly installed in head hoop respectively with earmuff, and the U-shaped borehole jack in supporting bracket is on backstay, both can relative movement, two ends are separately fixed at the back-moving spring in backstay and supporting bracket in addition, can automatically reset after making supporting bracket and earmuff pull-out.The resetting structure of this kind of earphone is very simple, and the elasticity that make use of spring can realize automatically reseting of earmuff, drastically increases the convenience of use, and applies reset thrust without the need to user, can avoid damaging because applying the improper earphone caused; One end of back-moving spring can be optionally fixed on backstay or head hoop, and the other end can optionally be fixed on supporting bracket or earmuff equally, can meet the user demand of difformity earphone, thus carries out available protecting to resetting structure, extends its useful life.
Description
Technical field
The utility model relates to headphone, particularly relates to a kind of earmuff automatic reset structure of earphone.
Background technology
Earphone is equipment audio signal being converted to voice output, and namely headphone is worn on the head, and is different from built-in earplug in non-intrusive duct.As shown in Figure 1, be the different using state schematic diagrames of existing headphone, comprise the elastic inverted u-shaped head hoop 101 of upper end, and be arranged at the earmuff 102 at U-shaped two ends, and earmuff can move along the end of head hoop.During use, head hoop is anchored on the human body crown, two earmuffs cover on the ear on both sides respectively, if the head sizes of user is less, earmuff can be tightened up in head hoop end, as illustrated on the left of Fig. 1; If the head sizes of user is comparatively large, can by earmuff from the pull-out of head hoop end, make the inner space of U-shaped larger, to meet the demand of user, as Fig. 1 right diagram, the earmuff difference in height D between two figure is the length of earmuff pull-out; And for ease of collection with place, being also to protect earphone from damage, after the user of pull-out earmuff finishes using, then needing to apply inside thrust to earmuff, make earmuff return back to state as shown in fig. 1 on the left-hand side.Although this kind of headphone can meet the user demand of different size human body, after finishing using, need user to push back to formerly tighten up position from being about to earmuff, be not easy to operation, and if even can earphone be damaged when user's mistake is exerted oneself.
Summary of the invention
The utility model aims to provide a kind of earmuff of headphone can automatically reset resetting structure, to improve ease of use, protects earphone from destruction simultaneously.
The earmuff automatic reset structure of earphone described in the utility model, comprise head hoop and earmuff, also has the supporting bracket connecting head hoop and earmuff, head hoop end is fixedly equipped with backstay, the upper end of supporting bracket has U-shaped hole, U-shaped borehole jack is on backstay and can it moves up and down relatively, and the lower end of supporting bracket is fixedly connected with earmuff; Also has reducible back-moving spring, one end of back-moving spring is connected on backstay or head hoop, and the other end is then connected on supporting bracket or earmuff, and the deformation direction of back-moving spring is consistent with the direction in U-shaped hole, and before deformation does not occur back-moving spring, supporting bracket is tightened up on head hoop.
The earmuff automatic reset structure of earphone described in the utility model, earmuff is relative with supporting bracket fixing, supporting bracket and head hoop then by the positioning action of U-shaped hole and backstay, relative motion in the stroke in U-shaped hole, thus earmuff is tightened up pull out on head hoop or from it.In use, user pulls out earmuff and is placed on ears, back-moving spring is elongated and deformation occurs, under the effect of its resilience force, earmuff and head hoop have the trend of move toward one another, but are held on human body by earmuff because of the deformation effect of head hoop, mutual frictional force is there is between earmuff and human body, the action direction of this power is contrary with the resilience force of back-moving spring, thus stops earmuff resilience, and is positioned by earmuff on human body ears; After finishing using, earphone takes off from ears by user, and the frictional force between human body and earmuff disappears, and namely earmuff again draws in head hoop end under the resilience force effect of back-moving spring.The resetting structure of this kind of earphone is very simple, and the elasticity that make use of spring can realize automatically reseting of earmuff, drastically increases the convenience of use, and applies reset thrust without the need to user, can avoid damaging because applying the improper earphone caused; One end of back-moving spring can be optionally fixed on backstay or head hoop, and the other end can optionally be fixed on supporting bracket or earmuff equally, can meet the user demand of difformity earphone, thus carries out available protecting to resetting structure, extends its useful life.

Embodiment
As shown in Figure 2,3, a kind of earmuff automatic reset structure of earphone, comprise head hoop 1 and earmuff 2, also has the supporting bracket 3 connecting head hoop and earmuff, head hoop end is fixedly equipped with backstay 4, the upper end of supporting bracket has U-shaped hole 5, and U-shaped borehole jack is on backstay and can it moves up and down relatively, and the lower end of supporting bracket is fixedly connected with earmuff; Also has reducible back-moving spring 6, one end of back-moving spring is connected on backstay or head hoop, and the other end is then connected on supporting bracket or earmuff, and the deformation direction of back-moving spring is consistent with the direction in U-shaped hole, and before deformation does not occur back-moving spring, supporting bracket is tightened up on head hoop.D is the telescopic distance of earmuff.
Head hoop 1 comprises and has flexible outside U-shaped bar 11, with the inner side adhesive tape 12 of inner side being installed on U-shaped end, the upper end of inner side adhesive tape is fixedly connected with outside U-shaped bar, lower end is by being connected with the bolt and nut cover of inner side adhesive tape through outside U-shaped bar simultaneously, wherein screw rod is backstay 4, and the U-shaped hole 5 of supporting bracket 3 is placed on the shaft of screw rod.The U-shaped borehole jack of supporting bracket is between outside U-shaped bar and inner side adhesive tape, and its structure is simple, can effectively prevent supporting bracket from coming off, and play better stroke positioning action; Simultaneously, backstay adopts screw rod, and screw rod and nut 41 can relative movements, by movement between the two and the space size between adjustable outside U-shaped bar and inner side adhesive tape, thus adjustment supporting bracket is held on elasticity between the two, make it again to match with the resilience force of back-moving spring, earmuff can be regulated better to be placed on comfortableness on human body.
Preferably, one end of back-moving spring 6 is fixed on backstay 4, and the other end is fixed in supporting bracket 3.Because the movement of earmuff mainly relies on stroke and its direction determined in U-shaped hole, so the two ends of back-moving spring are separately fixed on the part of backstay and these two relative motions of supporting bracket, the orientation consistency in spring and U-shaped hole can be ensured better, reduce the friction that the distortion on the non-resilient direction of spring causes spring with other part, make the reset of earmuff more smooth and easy simultaneously.
