Summary of the invention
Purpose of the present invention just is to overcome defects, the handset audio test automatic fixture device of development adjustable pressure.
Technical scheme of the present invention is:
The handset audio test automatic fixture device of adjustable pressure, the L bracket upper end connects vertical shaft electric machine, horizontal shaft electric machine is connected with the L bracket lower end, and its technical characteristics is that the automatic pressure bringing device is on the same direction of horizontal shaft electric machine, is connected on the tripod.
Advantage of the present invention and effect are and can add adjustable pressure at earpiece and ear, thereby can test the call performance that need to be close to ear in the actual use for the speech mobile phone of not hearing the other side.
Other concrete advantages of the present invention and effect will go on to say below.

The component names that each label is corresponding among the figure is as follows:
Vertical shaft electric machine 1, L bracket 2, vertical rotation support 3, tripod 4, horizontal shaft electric machine 5, earpiece 6, mobile phone hold assembly 7, dummy head 8, artitificial ear 9, mobile phone 10, artificial mouth 11, sliding screw 12, sleeve pipe 13, spring 14, mobile microphone 15, clip vertical support bar 16, anchor clamps horizontal support bar 17, support bar 18, fixed mount 19, horizontal slip motor 20, pressure sensor 21, pressure display unit 22, computer 23, control cabinet 24.
Embodiment
Shown in Fig. 1,2,3,4:
L bracket 2 upper ends connect vertical shaft electric machine 1, and horizontal shaft electric machine 5 is connected with L bracket 2 by on the tripod 4; Hold assembly 7 is connected with vertical shaft electric machine 1 by vertical rotation support 3, and hold assembly 7 clamps mobile phone 10; Be provided with earpiece 6, mobile microphone 15 on the mobile phone 10; Be provided with dummy head 8, artitificial ear 9, artificial mouth 11 on the model.
When carrying out audio-frequency test, the angle of the trunnion axis of the vertical axis of automatic rotation vertical shaft electric machine 1, horizontal shaft electric machine 5 as required, hold the measurement of angle to adapt to mobile phone 10 differences, save the artificial adjustment angle time, make test realize automation fully; Anchor clamps are connected with clip vertical support bar 16, clip vertical support bar 16 jockey horizontal support bars 17, anchor clamps horizontal support bar 17 is fixed on dummy head 8 the fixedly shelf 18, being fixed up between the mobile phone location of clamping and the dummy head position, be convenient to plus-pressure between earpiece and artitificial ear like this.
Add the important step that different pressure is the earpiece performance test at artitificial ear for the mobile phone of clamping, the implementation explanation of this pressurization: spring 14 (or other can produce the parts of pressure) is placed in sleeve pipe 13 the insides, come the tense-lax of control spring 14 with sliding screw 12, thereby produce different pressure by 2 pairs of earpiece of L bracket at artitificial ear, be sliding screw 12 past dextrorotation spring compressions, the pressure of earpiece on artitificial ear 9 strengthens; Sliding screw 12 is pressed pine toward left-handed spring, and the pressure of the receiver of mobile phone 10 on artitificial ear 9 reduces.
The fixing mode that also has other between anchor clamps and the dummy head 8, as shown in Figure 2:
What the explanation of the parts among Fig. 2 was different from Fig. 1 is: clip vertical support bar 16 jockey horizontal support bars 17, anchor clamps horizontal support bar 17 is fixed on the fixed mount 19 on dummy head 8 the body (or other parts), main effect is being fixed up between mobile phone 10 positions of clamping and dummy head 8 positions, being convenient to plus-pressure between the receiver on the mobile phone 10 and artitificial ear 9.
Pressure between receiver on the mobile phone 10 and the artitificial ear 9 can be manual adding, and also can be automatically to add.Self-pressurizing agri is as shown in Figure 3:
What the explanation of the parts among Fig. 3 was different from Fig. 1 is: spring 14 (or other can produce the parts of pressure) is placed in sleeve pipe 13 the insides, sliding screw 12 is not to regulate by hand, but controlled by horizontal slip motor 20, be that horizontal slip motor 20 slides to the left or to the right according to pressure sensor 22 drawn pressure value control sliding screws 12, the tense-lax of control spring 14, thus different pressure produced by 2 pairs of earpiece 6 of L bracket at artitificial ear 9.
Automatic pressure applies the further explanation of parts job step as shown in Figure 4:
Spring 14 is placed in sleeve pipe 13 the insides, sliding screw 12 is controlled by horizontal slip motor 20, a pressure sensor 22 is settled on the top, the right of spring 14, be used for measuring added pressure value, pressure value can show at pressure display unit 21, this pressure value is passed to computer 23, computer 23 drives sliding screw 12 by control cabinet 24 control horizontal shaft electric machines 5 conversely again and makes horizontal slip adjusting pressure to suitable value, thereby reaches automatically receiver and 9 purposes of exerting pressure of artitificial ear on mobile phone 10.
The custom difference that different people grasps mobile phone is very large, and the profile of mobile phone and size also difference are very large, and the user in order to catch the other side's sound, firmly is close to ear with earpiece sometimes when using mobile phone in addition, thereby produces pressure.Advantage of the present invention and effect can be carried out all automatic measurement of holding mobile phone communication under the machine different, and can apply different pressure at artitificial ear to mobile phone, satisfy the requirement of mobile phone receiving terminal performance test, guaranteed that like this high efficiency of test and test are comprehensive.
