Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

By Fig. 1 to Fig. 4 it is found that the earphone includes shell, is mounted on the intracorporal phonation unit 13 of the surrounded chamber of shell, the hair The surrounded cavity of shell is divided into the preceding operatic tunes and the rear operatic tunes by sound unit 13, is equipped in outer side of shell and is led sound with what the preceding operatic tunes was connected to Pipe 14；Further include switching construction, the switching construction include be rotatably arranged in phonocatheter 14 and radially extend shaft 21, Switching switch 23 on the outside of phonocatheter 14 for driving shaft 21 to rotate is set and is arranged in phonocatheter 14 and shaft 21 At least two watertight panels being fixedly connected, at least two watertight panels intersect at same straight line and coaxially set with shaft 21 Set, the waterproofing grade of at least two watertight panels is different, the shape of each watertight panel with 14 lumenal cross-section of phonocatheter Shape is adapted.

Switching construction for switching waterproofing grade is set on phonocatheter 14, due to being fixed with different preventing in shaft 21 The watertight panel of water grade, can by switching switch 23 drive shaft 21 rotate, make different waterproofing grade watertight panel and 14 inner cavity of phonocatheter matches, which can be adjusted waterproofing grade according to use environment, solves the waterproof of earphone The nonadjustable problem of grade.

In the present embodiment, switching switch 23 is fixedly connected with shaft 21, specifically, is arranged on switching switch 23 Mounting hole, 21 end of shaft are inserted into mounting hole and are fixed, in order to enhance shaft 21 and switch the switching performance of switch 23, in shaft It is toothed around on 21 ends.

Certainly, switching switch 23 can also be driven by way of gear, rack gear with shaft 21, switch switch 23 and Phonocatheter 14 is slidably connected.

In the present embodiment, watertight panel include flexible ring body, the waterproof layer that is arranged in ring body, at least two The ring body of watertight panel intersects at same straight line, and shaft 21 and the straight line are coaxially disposed；Specifically, watertight panel is provided with two A, the ring body of a watertight panel 22a is equipped with the waterproof layer of high waterproofing grade, the ring body installation of another watertight panel 22b There is the waterproof layer of low waterproofing grade, the waterproof layer of high waterproofing grade is usually to be made of waterproof membrane, the waterproof layer of low waterproofing grade Usually it is made of waterproof net cloth.Since ring body has certain elasticity, watertight panel and 14 inner sidewall of phonocatheter can be enhanced Between sealing performance, friction between the two can also be enhanced convenient for watertight panel positioning and fixing.

When watertight panel setting there are two when, the plane where watertight panel 22a, watertight panel 22b is mutually perpendicular to；Waterproof Panel is also provided with three, and three watertight panels, which are circumferentially divided equally, to be arranged, and certainly, watertight panel also can according to need and set It is set to other numbers.

In the present embodiment, annular groove is equipped on 14 inner sidewall of phonocatheter, when such watertight panel is gone at annular groove It is just caught in annular groove, enhances the positioning and fixing between watertight panel and 14 inner sidewall of phonocatheter.

In the present embodiment, shaft 21 is split type structure, the first split axle, the second split axle including coaxial arrangement, difference It is arranged at the both ends of ring body intersecting straight lines of at least two watertight panels.

In the present embodiment, in order to prevent when in use, the rotation of shaft 21 drives watertight panel rotation, leads to waterproofing grade It changes, position limiting structure is usually equipped between switching switch 23 and phonocatheter 14, which includes that setting is switching Retention bead on switch 23, be arranged on phonocatheter 14 and with the one-to-one limiting groove of watertight panel, rotation switching opens Closing 23 keeps it corresponding from different limiting grooves, and the watertight panel of different preventing water grade can thus be in phonocatheter 14 Chamber radially, with this changes waterproofing grade according to use environment.

In the present embodiment, containing groove 15 is equipped on 14 lateral surface of phonocatheter, it is recessed that switching switch 23 is mounted on accommodating In slot 15.

In the present embodiment, shell includes the rear shell 11 snapped together, front housing 12, and phonation unit 13 is mounted on rear shell 11 With the junction of front housing 12, the rear operatic tunes is surrounded between the phonation unit 13 and rear shell 11, between the phonation unit 13 and front housing 12 The preceding operatic tunes is surrounded, phonocatheter 14 is connected on front housing 12.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
