Description
Technical field
The present invention relates to handset audio field tests, particularly Automatic fixture for mobile phone audio test.
Technical background
Before making the present invention, the development of mobile phone market thereupon, mobile phone test number of devices and quality requirement are more and more high, and in traditional handset audio testing equipment, its mobile phone fixture is manual adjustments, namely manual adjustments mobile phone is relative to the angle of dummy head and position, not only consuming time, not automatic, do not support the clamping of more than five inches mobile phones, and the two axle anglecs of rotation are limited, new cell-phone testing requirement can not be met, the needs in factorial praluction, handset audio being carried out to test automatically cannot be adapted to.
Summary of the invention
Object of the present invention is just to overcome above-mentioned defect, development Automatic fixture for mobile phone audio test.
Technical scheme of the present invention is:
Automatic fixture for mobile phone audio test, its technical characteristics is that L bracket upper end connects vertical shaft electric machine, and lower end connects horizontal shaft electric machine, and hold assembly connects vertical shaft electric machine.
Advantage of the present invention and effect are not produce noise, and do not affect handset audio test, can continue automatically to test, lightweight, minimize the impact of handset audio and radio frequency, be applicable to the mobile phone of multiple size dimension, efficiency is high.
Other concrete advantages of the present invention and effect will go on to say below.
Accompanying drawing explanation
Fig. 1---general structure schematic diagram (parts explosion) of the present invention.
Fig. 2---the present invention totally uses schematic diagram (installation diagram).
Fig. 3---method of measurement schematic diagram of the present invention.
The component names that in figure, each label is corresponding is as follows:
Vertical shaft electric machine 1, L bracket 2, left bolt 3, tripod 4, horizontal shaft electric machine 5, hold assembly 6, bolt 7, cross positioning device 8, right bolt 9, mobile phone 10, dummy head 11, artitificial ear 12, artificial mouth 13, earpiece 14, mobile microphone 15, vertical axis 16, trunnion axis 17.
Embodiment
As shown in Figure 1 and Figure 2:
L bracket 2 upper end connects vertical shaft electric machine 1, and horizontal shaft electric machine 5 is connected with L bracket 2 through the hole on tripod 4; Hold assembly 6 upper end is connected with vertical shaft electric machine 1 by left bolt 3, connects cross positioning device 8 in the middle part of hold assembly 6 by bolt 7, and mobile phone 10 is connected on hold assembly 6 by right bolt 9; Mobile phone 10 is provided with earpiece 14, mobile microphone 15; Model is provided with dummy head 11, artitificial ear 12, artificial mouth 13.
Application process of the present invention illustrates:
When carrying out audio-frequency test, can the angle of the vertical axis of automatic rotation vertical shaft electric machine 1, the trunnion axis of horizontal shaft electric machine 5 as required, to adapt to the measurement that mobile phone 10 difference holds angle, save the artificial adjustment angle time, make test realize automation completely; Tripod 4 is main supporters, in the above fixing horizontal spindle motor 5; Send instructions to the motor drive controller of vertical shaft electric machine 1, horizontal shaft electric machine 5 by computer, system can automatically, accurately level of control, the vertical anglec of rotation, while the position not changing earpiece and artitificial ear, change relative position and the angle of mobile microphone and artificial mouth, realize handset audio testing standard demand.
As shown in Figure 2:
Two stepping motors and vertical shaft electric machine 1, horizontal shaft electric machine 5 form clamp rotating mechanism, horizontal shaft electric machine 5 is stepping reducing motors, vertical shaft electric machine 1 is stepping reducing motor, realize fixture and rotate control at accurate angle that is vertical, level two axles, keep earpiece 14 invariant position, to meet the requirement of handset audio testing standard simultaneously; During installation testing mobile phone 10, earpiece 14 aims at the cross intersection point of cross positioning device 8, can ensure that earpiece 14 is at intersection point that is vertical, level two rotating shafts, to ensure that in rotary course, earpiece 14 remains unchanged relative to the center of artitificial ear 12, after installation, take off cross positioning device 8 from the side, test.
Vertically, the vertical shaft electric machine 1 of level two axles, horizontal shaft electric machine 5 Electric Machine Control control and drive system are by serial port and dataphone, controller action instruction is controlled by the mobile phone test software of computer end, realize trunnion axis 180 degree of scopes at horizontal shaft electric machine 5 place, Arbitrary Rotation in the middle of vertical axis 90 degree of scopes at vertical shaft electric machine 1 place, resolution 0.0003 degree, simultaneously earpiece 14 be positioned at vertically, the intersection point of level two rotating shafts, in rotation, ensure invariant position; Ensure time cross positioning device 8 is for installing mobile phone 10 that earpiece 14 is at intersection point that is vertical, level two axles.
Two stepping motors and vertical shaft electric machine 1, horizontal shaft electric machine 5 be stepping big retarding than motor, forward position to, Systematical control off line cuts off self-lock, and during test, fixture does not produce noise completely, does not affect handset audio test.
Step angle 1.8 degree, reduction box speed reducing ratio 1: 36, driver segmentation 128, motor often makes a move, and deceleration rear output shaft rotates: 1/2560 degree, and with return difference angle compensation, the accurate angle realizing 2 axles controls; Vertical shaft electric machine 1 and the reduction box speed reducing ratio of horizontal shaft electric machine 5 are 1: 36, one can export enough torques, and two is improve anglec of rotation resolution, and three is realize reverse self-locking.
Hold assembly 6 adopts the frame structure of aluminum alloy of hollow out, lightweight, minimizes the audio frequency of mobile phone 10 and the impact of radio frequency.
Six adjusting bolts, achieve different in width, and the clamping of thickness mobile phone regulates, and well can clamp greatly to seven inches of mobile phones on this fixture.Top is furnished with rubber cap, for the protection of mobile phone.
The custom difference that different people grasps mobile phone is very large, and also difference is very large for the profile of mobile phone and size in addition.Advantage of the present invention and effect can carry out all automatic measurement of mobile phone communication under difference holds machine.Before solving like this handset audio test fixture manually and the restriction being less than five inches of mobile phones can only be pressed from both sides, ensure that the high efficiency of test and test comprehensive.
As shown in Figure 3:
In order to measure the mobile phone use habit of different user, mobile phone is positioned in the hold assembly 6 of test automatic fixture device, with fixing mobile phone; When measuring beginning, the artificial mouth on dummy head is aimed in the microphone bar road of mobile phone, and using this position as 0 degree, namely tests the initial position of grasping.Predetermined near-end sound play by artificial mouth, to imitate cellphone subscriber oneself voice.Sound after handset processes is sent in computer by radio or cable by mobile phone, and computer is analyzed received sound, calculated, and draws the assessment result of collecting speech quality.After an angle position measures, the vertical shaft electric machine of automatic fixture and horizontal shaft electric machine control hold assembly respectively and forward next pre-set angle position to, repeat above measurement, analysis, calculating, to show that mobile phone difference holds the assessment result of the speech quality of machine angle, the angle position preset until all is all measured complete.
