Description
(1) technical field
The present invention relates to a kind of headset detection equipment, particularly a kind of force test device for earphone head ring.
(2) background technology
At present, the test of earphone headring power does not also have special-purpose measurement mechanism, it is 145mm in two earphone horizontal intervals that pure tone audiometer vertification regulation JJG388-2001 requires, test earphone headring power in the situation that the headring height is 129mm, earphone headring power is related to the result of hearing diagnosis, is related to people's physical and mental health.
The current employing spring tension of test meter to earphone headring power is tested, but this method is difficult to guarantee horizontal interval and the headring height of two earphones, and measuring accuracy does not reach requirement yet, operates also inconvenient.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, provide a kind of easy and simple to handle, measure force test device for earphone head ring accurately.
The present invention is achieved through the following technical solutions:
A kind of force test device for earphone head ring, comprise base, it is characterized in that: be provided with symmetrical dovetail groove on described base, and be provided with sleeve pipe between two dovetail grooves, be movably installed with respectively fixed mount first and fixed mount second by trip bolt in two dovetail grooves, fixed mount first top connects as one by screw and emulation concha auriculae, fixed mount second top connects as one by screw and pressure transducer, artificial ear second is arranged on the pressurized screw rod of pressure transducer, and pressure transducer is connected with pressure display unit by signal wire; Support bar is set in sleeve pipe and the height adjustment knob of controlling support bar is installed on sleeve pipe, be provided with the vertical scale chi on support bar.
The present invention arranges emulation concha auriculae, artificial ear second and support bar, tested earphone is covered on respectively on emulation concha auriculae and artificial ear second, headring is placed on support bar, by regulating the spacing of the definite two tested earphones of distance between fixed mount first and fixed mount second, determine the headring height by the height of adjusting support bar, working pressure sensor sensing earphone heads ring compression, be presented on pressure display unit, by data, reads the grasp concrete condition.
More excellent scheme of the present invention is:
Described base upper surface is fixed with the horizontal scale chi parallel with dovetail groove, by the sign of rule, accurately grasps the distance between emulation concha auriculae and artificial ear second.
On four pin of described base, height-adjustable knurled nut all is installed, the upper surface of base is provided with the level indication, uses the horizontality of knurled nut's adjusting base, and indicates to observe by level and determine.
Described emulation concha auriculae and artificial ear second all are frustum, and cylindrical hole is drawn in centre, and material adopts plastics, stressed to reduce the pressure transducer vertical axial.
Described pressure display unit is the digital display display, is convenient to get information about earphone heads ring compression situation.
The present invention is simple in structure, easy and simple to handle, reasonable in design, and applying flexible can accurately and reliably be measured the earphone heads ring compression, is suitable for wide popularization and application.
