Technical field
The present invention relates to a kind of earphone, relate in particular to a kind of earphone of scalable clamping power or have the earphone of microphone.
Background technology
Headphone all is the connecting rod that utilizes between the and arranged on left and right sides earphone usually, as: the elastic force of plastics or bonding jumper is clamped ear as the folder power of earphone, can clamp reliably in order to make earphone, production or designing unit often adopt the folder power bigger than actual needs to come clamping, because excessive chucking power, and can not adjust the size of power effectively, therefore when using earphone for a long time, will cause earache and headache brain to expand because of folder power is excessive, not only have influence on healthyly, joyful mood has also fallen sharply.
Summary of the invention
Main purpose of the present invention is in order to overcome above-mentioned deficiency, a kind ofly can regulate the earphone of a kind of scalable clamping power of ear folder power according to user's needs thereby develop.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of earphone of scalable clamping power, has the earphone body, the connecting rod that links to each other with the earphone body, it is characterized in that: the connecting rod that links to each other with the earphone body is divided into left and right two, adopt hinge to connect between two, the centre is provided with the chucking power governor motion; Described chucking power governor motion comprises the support hinged with left and right connecting rod, the connecting rod holder hinged with left and right connecting rod end, between support and the connecting rod holder, regulate the adjusting screw(rod) of distance between support and the connecting rod holder, adjusting screw(rod) that in other words can the lifting of control connection bar holder.
Technical scheme of the present invention can also be further perfect:
As preferably, the end of described left and right connecting rod is connected with bearing pin, and bearing pin is generally with the end of connecting rod fixedlys connected; The left and right two ends of described connecting rod holder are provided with bearing pin and match, also can make the left and right connecting rod that links to each other with bearing pin to make the cotter-pin hold that to a certain degree rotates.The extent of opening of pin-and-hole is less than the pin-and-hole diameter, and can make that the left and right connecting rod that links to each other with bearing pin rotates along with the rotation of bearing pin may.Bearing pin inserts from side of cotter-pin hold, until the block face of another side of pin-and-hole with till connecting rod contacts.
As preferably, a side of described connecting rod holder is equipped with fixed cap; Have on the described fixed cap and corresponding two circular holes of cotter-pin hold, the end that is used for bearing pin is passed through, and periphery has the installation aperture, described installation aperture and tight fit corresponding with the cylinder that protrudes from the holder side.
As preferably, it is characterized in that: the two ends of described support have opposed anteroposterior connecting hole; Described left and right connecting rod is provided with slotted eye; Described connecting hole matches with slotted eye, is connected the end of latch and the connecting hole close-fitting on the support with latch between described connecting hole and the slotted eye.
As preferably, the end of described adjusting screw(rod) is provided with regulating handle, the slotted collar that screw rod is provided with upper and lower two cannelures and cooperates with cannelure; When installment state, adjusting screw(rod) is entered by the hole of support end face, be threaded with the screw that is connected on the connecting rod holder, last cannelure is positioned on the screw rod of support inside top surface face, following cannelure is positioned on the screw rod that connects the screw lower plane, being with slotted collar on upper and lower cannelure can not reach adjusting screw(rod) and can not deviate from stent cover screw rod from connecting in the screw.
Therefore, beneficial effect of the present invention is because on the connecting rod between two earphones, be provided with according to lever principle invent, the governor motion of aperture between left and right two earphones of scalable, thereby reach the purpose of the chucking power of regulating earphone, it is simple in structure, and is easy to use; The user can be according to personal habits, adjusts ear folder power, make wear comfortable.

Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment:
As the ear microphone of Fig. 1 to scalable clamping power shown in Figure 7, left and right earphone 10 is arranged, the left and right connecting rod 4 that links to each other with left and right earphone, the end of connecting rod 4 is fixed with bearing pin 42, the length of bearing pin slightly is longer than connecting rod 4 width, and connecting rod has the slotted eye 41 of radial arrangement near leading section.In the end of left and right connecting rod 4 connecting rod holder 6 is arranged, see shown in Figure 4ly, Fig. 4 a is connecting rod holder 6 stereograms, and Fig. 4 b is a front view.The left and right two ends of connecting rod holder are provided with bearing pin 42 and match, also can make the left and right connecting rod that links to each other with bearing pin to make the cotter-pin hold 61 that to a certain degree rotates, the extent of opening of pin-and-hole is less than the pin-and-hole diameter, and can make that the left and right connecting rod that links to each other with bearing pin rotates along with the rotation of bearing pin may.The screw 63 of connection is arranged above the connecting rod holder, and a side of holder is equipped with fixed cap 7, sees shown in Figure 6.Have on the fixed cap and corresponding two circular holes 72 of cotter-pin hold, the end that is used for bearing pin is passed through, and periphery has four aperture 71 is installed, and aperture and four cylinders, the 62 corresponding and tight fits that protrude from the holder side are installed.Support 2 is arranged on connecting rod holder 6, see shown in Figure 3ly, Fig. 3 a is a stereogram, and Fig. 3 b is a front view.The end face of support porose 22, be used to install adjusting screw(rod) 1, two ends have opposed anteroposterior four connecting holes 21, connecting hole matches with slotted eye 41 on the left and right connecting rod, be connected with latch 8 between connecting hole and the slotted eye, the connecting hole 21 on the end of latch and the support 2 is close-fitting mutually.The end of adjusting screw(rod) 1 is provided with regulating handle, and screw rod is provided with upper and lower two cannelures 11,12, (see figure 7) and the slotted collar 3 that cooperates with cannelure.
