Specific embodiment

The technical solution of the utility model is described in further detail with reference to the accompanying drawings and detailed description, this Utility model proposes a kind of embodiment of earphone, and referring to Fig.1 shown in-Fig. 4, the earphone in the present embodiment is intelligent earphone, in The battery 200 that portion is provided with control panel 100 and can power, battery 200 can be electrically connected with control panel 100, for control panel 100 And the device power supply on control panel 100, it specifically further include having shell 300, the loudspeaker being arranged in shell 300 440, in institute It states and is provided with sound outlet hole 310 corresponding with 440 position of loudspeaker on shell 300, specifically, shell 300 includes front housing 320 with after Shell 330, loudspeaker 440 are fixed in rear shell 330, and sound outlet hole 310 is provided on front housing 320, and the button of front housing 320, which is set, is fixed on rear shell It on 330, is used for convenience of wearing, is provided in rear shell 330 in the present embodiment and wears item 331, be arranged with ear on front housing 320 Plug 800.

One shield 400 of setting is rotated with 310 position corresponding position of sound outlet hole on shell 300, it is preferred that shield 400 It can be rotatably arranged on shield 400 by a shaft 900, the occlusion part for blocking sound outlet hole 310 is provided on shield 400 410 and evacuation sound outlet hole 310 relief portion 420, rotate shield 400 after energization is provided on shield 400 and shell 300 Make the actuation component 500 corresponding with 310 position of sound outlet hole of relief portion 420, it is preferred that the actuation component 500 in the present embodiment wraps Include the electromagnet that the permanent magnet 510/ being arranged on the shield 400 electromagnet 520 He is arranged on the shell 300 Permanent magnet can be selected in 520/ permanent magnet 510, permanent magnet 510, and electromagnet 520 selects electromagnet, the permanent magnet 510 and electromagnet 520 are arranged and have between the two at regular intervals along the circumferential direction of shield 400.In shield in the present embodiment Be provided with permanent magnet 510 on 400, be provided with for electromagnet 520 and be illustrated on shell 300, electromagnet 520 it is electric when It can produce magnetism, the electric mode that obtains of electromagnet 520 can be single when earphone complete machine is switched on while after powering on or be switched on to electromagnet 520 Solely control powers on, and electromagnet 520, which powers on, mainly to be provided by battery 200, and control panel 100 can be used for controlling battery 200, make its to The power supply of electromagnet 520 is disconnected to the power supply of electromagnet 520, obtains electric or power loss control for realizing electromagnet 520.

Electromagnet 520 it is electric after can generate magnetive attraction, since permanent magnet 510 and electromagnet 520 are separately positioned on shield 400 and shell 300 on and between the two have spacing, electromagnet 520 generate magnetive attraction can then be attracted permanent magnet 510, in turn Shield 400 is driven to rotate, both final permanent magnet 510 and electromagnet 520 are pulled together, at this point, can be by being rationally arranged Both permanent magnet 510 and electromagnet 520 angle corresponding to the segmental arc on shield 400, so that shield 400 turns to It can just make relief portion 420 and 310 position of sound outlet hole corresponding when 520 attracted position of permanent magnet 510 and electromagnet.

A dynamic clamping head and quiet clamping head 600 is also set up in the present embodiment, dynamic clamping head and quiet clamping head 600 is connected to shield 400 and shell 300 On, when shield 400 is acted on by the suction-combining force and being rotated, meeting tensile elasticity return unit 600 disappears being attracted 500 the suction-combining force of component After mistake, dynamic clamping head and quiet clamping head 600 will restore elastic deformation, and shield 400 will be driven to do resetting movement together, set on shell 300 Be equipped with the locating part 700 that limitation shield 400 rotates, by the limit of locating part 700 so that shield 400 stop at it is specified Position, occlusion part 410 is corresponding with sound outlet hole position at this position, when limiting the reset of shield 400 by locating part 700 Rotatable angle makes reset position be located just at 310 position corresponding position of occlusion part 410 and sound outlet hole, realizes to sound outlet hole 310 Block.

Preferably, the dynamic clamping head and quiet clamping head 600 in the present embodiment is spring, and one end of which is fixed on the shields 400 On, it is specifically fixed on the permanent magnet 510 of shield 40, the other end is fixed on the shell 300.Further, in institute It states and is provided with fixing piece 330 on shell 300,600 other end of dynamic clamping head and quiet clamping head is fixedly connected with the fixing piece 330.

Further, further include a shielding cover 810 for being blocked to actuation component 500 and dynamic clamping head and quiet clamping head 600, The shielding cover 810 is fixed on the shell 300.On the one hand internal fit structure can be blocked by shielding cover 810, On the other hand it can prevent from scratching user.

Preferably, the locating part 700 is located on the shell 300 at 400 peripheral position of shield, and locating part 700 is main For limiting to the permanent magnet 510 being arranged on shield 400, and then realize the limit to entire shield 400, limit Part 700 can select limited block.

Preferably, the occlusion part 410 in the present embodiment is with the relief portion 420 along the circumferential direction of the shield 400 Direction is alternatively arranged setting, and the relief portion 420 is to be provided with identical with 310 shape of sound outlet hole on the shield 400 keep away It allows hole, is occlusion part 410 between 2 adjacent avoid holes.

The use process of earphone in the present embodiment are as follows: when needing using earphone, carrying magnetic is powered on to electromagnet 520, Permanent magnet 510 is attracted under magneticaction, shield 400 rotates, and permanent magnet 510 is attached together with electromagnet 520, and spring is drawn It stretches, relief portion 420 is overlapped with 310 position of sound outlet hole, and sound outlet hole 310 all exposes, at this point, earphone is in " working condition ", is used Family can be used normally earphone and listen to music.After use, control panel 100 controls 520 power down of electromagnet and loses magnetism, permanent magnetism Adsorption capacity between body 510 and electromagnet 520 disappears, and spring is sprung back under the effect of elasticity, and shield 400 is pulled to rotate backward, Movement stops when permanent magnet 510 goes to 700 position of locating part, and sound outlet hole 310 is corresponding with 410 position of occlusion part at this time, sound outlet hole 310 are just all covered, and front housing 320 is sealed off, and earphone is in " guard mode ", extraneous different under " guard mode " Object, dust and air are all isolated, cannot be introduced into earphone inner cavity, when earphone falls or squeezes ear muff, air can not also be impacted Loudspeaker diaphragm improves whole protective performance to play the role of protecting loudspeaker 440.

Above embodiments are only to illustrate the technical solution of the utility model, rather than are limited；Although referring 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 documented by 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.
