Accompanying drawing explanation
By the description carried out its exemplary embodiment below in conjunction with accompanying drawing, the above-mentioned feature and advantage of the utility model will become apparent and easy understand.
Fig. 1 is the utility model embodiment overall structure schematic diagram;
Fig. 2 is the structural representation I of the utility model earphone cord syndeton;
Fig. 3 is the structural representation II of the utility model embodiment earphone cord syndeton.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, so that the understanding of technical staff of the same trade:
As Figure 1-3, a kind of line changeable formula earphone cord syndeton of built-in earplug is provided in the present embodiment, the same with conventional built-in earplug, it earphone cord 3 comprising two earplug body 1 (because earplug body, headset plug and earphone cord structure are those skilled in the art's routine techniques, therefore only drawing an earplug body in accompanying drawing 1), headset plug 2 and be connected between earplug body 1 and headset plug 2.Wherein: the earplug set 12 that earplug body 1 comprises shell 11, is located at the loud speaker (not shown) in shell 11 and is socketed on shell 11, earplug set 12 is made up of low resilience material.Headset plug 2 is 3.5mm headset plug.Earphone cord 3 is quad, comprises L channel line, R channel line, L channel ground wire, R channel ground wire.
Be different from conventional built-in earplug:
Shell 11 is convexly equipped with audio terminal 13, audio terminal 13 is roughly in cylindrical shape.Its end face is provided with the fixed contact 131 that two are electrically connected loud speaker in shell 11, and the center of its end face depression is provided with a location hole 132.In addition, the sidewall of audio terminal 13 is equipped with groove 133.Grooved section shape is that minor arc is arc.
The other end of the relative headset plug 2 of earphone cord 3 is provided with sub-plug 31, and sub-plug is the Y type plug of two-phase in the present embodiment, and it is electrically connected headset plug 2 by earphone cord 3, and the left/right sound channel positive pole distinguished on corresponding headset plug 2 and region.Sub-socket 31 is also provided with the first buckle structure 311.
Conversion seat 4, its one end is provided with the sub-socket 41 with sub-plug 31 male-female engagement, and the other end is provided with audio terminal 13 shape adaptation and may correspond to the source of sound plug socket 42 of grafting.
Be provided with reed 412 in sub-socket 41, and be provided with the second buckle structure 411, when sub-plug 31 is plugged in sub-socket 41, second buckle structure 411 and the first buckle structure 311 snapped into one another,, in the present embodiment, the first buckle structure 311 is trip, and the second buckle structure 411 is hole clipping.
Source of sound plug socket 42, barrel-shaped in audio terminal 13 shape adaptation of source of sound plug socket 42, source of sound plug socket 42 and audio terminal 13 may correspond to grafting.The bottom surface of source of sound plug socket 42 is provided with two contacts 421 be electrically connected by core in earphone cord 3 and headset plug 2, and the place of bottom center of source of sound plug socket 4 is convexly equipped with the alignment pin 422 with location hole 132 form fit.Source of sound plug socket 4 is made up of flexible material around the tube wall 423 of bottom surface, and the inner side of tube wall 423 forms the flange 4231 with groove 133 shape adaptation.
