3 upper end of bottom panel is stated, the elastic telescopic device 5 is arranged between the top panel 3 and bottom panel 4, sets on the top panel 3
Artificial ear 2 and weighting material 7 are equipped with, when earmuff is tested, the top panel 3 is pressed on the earmuff.
Headset ear shell test device primary structure includes：For the artificial mouth 1 for realizing testing earmuff acoustical behavior
With artificial ear 2, artificial mouth 1 is mainly used in sounding, and artificial ear 2 is used to measure；To passive 3 He of top panel of whole device
Bottom panel 4, top panel 3 and bottom panel 4 are mode setting up and down, and bottom panel 4 is arranged below, and top panel 3 is disposed over,
The elastic telescopic device 5 of one achievable elastic compression function, elastic telescopic device 5 are set between top panel 3 and bottom panel 4
Can be to top panel 3 with resilient force upwards when by compression force, it is to avoid the deadweight of top panel 3 and artificial ear 2
It is applied on the earphone fore shell imitation shape piece 6 arrange on bottom panel 4, increases the pressure to being arranged on earphone fore shell imitation shape piece 6,
The test of earmuff acoustical behavior is hampered, earphone fore shell imitation shape piece 6 is, according to using the good fore shell of headset designs, to carry out earphone
When earmuff is tested, earmuff is arranged on earphone fore shell imitation shape piece 6.
Weighting material is placed on top panel 3, weighting material is added accordingly by the size of the earmuff chucking power for measuring
Quantity, while artificial ear 2 is arranged on top panel 3 accordingly, with the bottom panel 4 of 3 opposite side of top panel on earphone is set
Fore shell imitation shape piece 6, so may insure to press when top panel 3 declines and is set to the earmuff for being arranged on earphone fore shell imitation shape piece 6
On, realize the detection to earmuff acoustical behavior.
Specifically, elastic telescopic device 5 is primarily implemented in top panel 3 and is not affected by when the effect of driving means 8 declines to top surface
Plate 3 is with elastic acting force, and elastic telescopic device 5 can follow the pressure size change that top panel 3 is produced when declining, and make top surface
What plate 3 was subject to makes a concerted effort upwards, and artificial ear 2, the impact of the deadweight of top panel 3 are excluded when measuring so as to may be implemented in.
Preferably, the elastic telescopic device 5 includes sliding bar 51 and spring 52, one end and the test of the sliding bar 51
Table is fixedly connected, and the other end successively passes through the bottom panel 4 and top panel 3, the spring 52 to be arranged on the top panel 3 and bottom
On sliding bar 51 between panel 4.Sliding bar 51 is vertically set on test desk, and spring 52 is sleeved on sliding bar 51, can edge
Sliding bar 51 is slided up and down, the then corresponding compression spring 52 when top panel 3 declines, while the elastic reaction reality by spring 52
The now support to offer 3 stress of top panel, when top panel 3 is not affected by the driving effect of driving means 8, top panel 3 is in gravity
In the presence of decline, now spring 52 produce elastic acting force, balance artificial ear 2, the deadweight of top panel 3, can in top panel 3
To touch when earmuff, it is upwards, thus that what the elastic acting force that spring 52 is provided should make that top panel 3 is subject to make a concerted effort
The impact of 2 grade deadweight of artificial ear is eliminated, the power that earmuff can bear can be measured by the weight of weighting material 7.
Preferably, the elastic telescopic device 5 is provided with 2 groups, is symmetricly set on the two of the top panel 3 and bottom panel 4
End.Elastic telescopic device 5 is separately positioned on the uniformity that the two ends of top panel 3 and bottom panel 4 may insure 3 stress of top panel,
Guarantee that top panel 3 smoothly can be lifted.
Further, the driving means 8 include pneumatic chute 81, aerodynamic slider 82, airway 83 and pneumatic source, described
