Detailed description of the invention
As shown in Figures 1 to 4, the bluetooth earphone that the utility model proposes, including: ear casing 1, circuit board 2, battery 3 gill
Head 4, ear casing 1 is fixed connected and composed by face-piece 11 and shell on the back 12.Circuit board 2 and battery 3 are all located in ear casing 1, pass through
Battery 3 powers to circuit board 2, and circuit board 2 is provided with miaow head, and ear casing 1 is provided with the switch key being connected respectively with circuit board 2
5 and volume adjusting button 6, it is provided with the charging socket being connected with battery 3 bottom ear casing 1.Earphone heads 4 is arranged on ear casing 1
Top, earphone heads 4 be provided with one end of receiver loudspeaker be receiver end, one end of being arranged on ear casing 1 be hinged end, receiver end
It is cased with earphone cap 7.
As it is shown in figure 5, be additionally provided with outside speaker 10 in ear casing 1, shell on the back 12 is provided with outside speaker 10 aligned in position
Sender 14, ear casing 1 outer ring is provided with and the ornamental strip 15 of sender 14 aligned in position, is provided with switching receiver loudspeaker in ear casing 1
With the magnetic induction switch of the on off state of outside speaker 10, the hinged end of earphone heads 4 is provided with the magnetic that can trigger magnetic induction switch
Property contact, magnetic contact is closer or far from magnetic induction switch when rotating for hinged end, and the magnetic red sheet in magnetic induction switch will be by
Sensing, thus contact turns off or on, and produces the signal on off state with switching receiver loudspeaker with outside speaker 10.Earphone heads 4
When turning to ear casing 1 top, receiver loudspeaker cut out, outside speaker 10 is opened, and when earphone heads 4 turns to ear casing 1 side, listen
Cylinder loudspeaker are opened, outside speaker 10 is closed.
As shown in Figure 5,6, the top outer of shell on the back 12 is provided with rotation hole 13, and rotation hole is uncovered U-shaped upward.Earphone heads
Cross a jointed shaft on the hinged end of 4, the two opposite side walls of rotation hole 13 is respectively equipped with hinge hole, towards face-piece on hinge hole
The inner side of 11 is provided with socket, and the two ends of jointed shaft are inserted two hinge holes respectively from spigot.The inner side of rotation hole 13 is the most fixing
Having a mounting seat 8, mounting seat 8 is fixed by screws in rotation hole 13, the hinged end of earphone heads 4 be mounted seat 8 be limited in turn
In dynamic hole 13.
As shown in Figure 7,8, the hinged end of earphone heads 4 is semicircle, and hinged end is additionally provided with an outwardly fixture block
41, in mounting seat 8, the one side towards hinged end is provided with cambered surface of rotating, and this cambered surface of rotating abuts with hinged end, and cambered surface of rotating sets
There is upper limit recess 81 and the lower limit recess 82 that can accommodate fixture block 41.In the present embodiment, rotatable 100 ° of earphone heads 4, fixture block
41 when being positioned at lower limit recess 82, and earphone heads 4 is positioned at the over top of ear casing 1, when fixture block 41 is positioned at upper limit recess 81, and ear
Head 4 is positioned at the top side of ear casing 1.
Preferably, cambered surface of rotating is provided with the chute 83 being connected between upper limit recess 81 and lower limit recess 82, sliding
The degree of depth of groove 83 is less than upper limit recess 81 and lower limit recess 82.During slip earphone heads 4, fixture block 41 tight against in chute 83 also
Sliding along chute 83, stop operating when fixture block 41 slips into upper limit recess 81 or lower limit recess 82, rotational structure stably may be used
Leaning on, during rotation, hands can clearly experience whether earphone heads 4 rotate in place, and experience is preferable.
Preferably, mounting seat 8 is additionally provided with the most tangent upper limit plane 84 being connected to cambered surface of rotating two ends and lower limit
Face 85, when fixture block 41 inserts upper limit recess 81, lower limit plane 85 abuts with earphone heads 4, and fixture block 41 inserts lower limit recess 82
Time, upper limit plane 84 abuts with earphone heads 4.Arranging of confined planes can effectively prevent external force inordinate rotation earphone heads 4, causes rotation
Structural failure lost efficacy, and extended the service life of bluetooth earphone.
