The utility model is realized through following technical scheme:
A kind of earphone headring force test device; Comprise base; It is characterized in that: said base is provided with symmetrical dovetail groove, and between two dovetail grooves, is provided with sleeve pipe, is movably installed with fixed mount first and fixed mount second respectively through trip bolt in two dovetail grooves; Fixed mount first top connects as one through screw and emulation concha auriculae; Fixed mount second top connects as one through screw and pressure transducer, and artificial ear second is installed on the pressurized screw rod of pressure transducer, and pressure transducer links to each other with pressure display unit through signal wire; Support bar is set in the sleeve pipe and the height adjustment knob of controlling support bar is installed on sleeve pipe, support bar is provided with the vertical scale chi.
The utility model is provided with emulation concha auriculae, artificial ear second and support bar; Tested earphone is covered on respectively on emulation concha auriculae and the artificial ear second, and headring places on the support bar, confirms the spacing of two tested earphones through the distance between adjusting fixed mount first and the fixed mount second; Height through the adjustment support bar is confirmed the headring height; Working pressure sensor sensing earphone heads ring compression is presented on the pressure display unit, reads the grasp concrete condition through data.
The more excellent scheme of the utility model is:
Said base upper surface is fixed with the horizontal scale chi parallel with dovetail groove, accurately grasps the distance between emulation concha auriculae and the artificial ear second through the sign of rule.
On four pin of said base height-adjustable knurled nut is installed all, the upper surface of base is provided with the level indication, the horizontality of using the knurled nut to regulate base, and observe definite through the level indication.
Said emulation concha auriculae and artificial ear second all are frustum, and cylindrical hole is drawn in the centre, and material adopts plastics, and is stressed to reduce the pressure transducer vertical axial.
Said pressure display unit is the digital display display, is convenient to get information about earphone heads ring compression situation.
The utility model is simple in structure, and is easy and simple to handle, reasonable in design, and applying flexible can be measured the earphone heads ring compression accurately and reliably, is suitable for wide popularization and application.
