Embodiment
As shown in Figure 1 and Figure 2, the testing equipment of notebook computer sound, comprise that notebook computer placement tool 1, horn testing device 2, microphone testing apparatus 3 and microphone paste lid arrangement 4, horn testing device 2 is positioned at the right side that notebook computer is placed tool 1, horn testing device 2 comprises lead screw motor 21 and test microphone 22, as shown in Figure 3, test is installed on the moving lever of lead screw motor 21 with microphone 22, and lead screw motor 21 can drive test and move to directly over the loudspeaker of the notebook computer to be measured on the notebook computer placement tool 1 with microphone 6; Microphone testing apparatus 3 is positioned at the left side that notebook computer is placed tool 1, the loudspeaker of microphone testing apparatus 3 are relative with the microphone that notebook computer is placed the notebook computer to be measured on the tool 1, and the spacing between the microphone of the notebook computer to be measured on the loudspeaker of microphone testing apparatus 3 and the notebook computer placement tool 1 is 150mm; Microphone paste lid arrangement 4 be positioned at notebook computer place the notebook computer to be measured on the tool 1 microphone under, microphone pastes lid arrangement 4 and comprises the subsides lid pressure head 41 that rotation integrates mechanism 42 with rectilinear motion and is mounted thereon, as shown in Figure 4, rotation and rectilinear motion integrate mechanism 42 and can drive to paste and cover pressure head 41 malleations on the microphone of the notebook computer to be measured on the notebook computer placement tool 1.
Such as Fig. 5, shown in Figure 6, rotation integrates mechanism 42 with rectilinear motion and comprises linear electric motors 421, turning arm 422, slide block 423 and nut 424, the screw mandrel of linear electric motors 421 and nut 424 screw and connect and compose the worm drive pair, nut 424 places on the line slideway, nut 424 links to each other with slide block 423 by connecting rod 425, slide block 423 places on the line slideway, slide block 423 is hinged with turning arm 422, slide block 423 belows are provided with roller devices 426, roller devices 426 comprises a upper roller and a pair of directive wheel, upper roller places the kidney slot on the turning arm 422, and directive wheel contacts with the bottom surface of turning arm 422.
The lead screw motor 21 that adopt horn testing device 2 realize that the test of rectilinear motion driven in synchronism on it is with microphone 22 motions, during test position when test moves to the loudspeaker of the notebook computer to be measured on the notebook computer placement tool 1 with microphone 22 directly over, the notebook loudspeaker carry out playback, test is included with 22 pairs of sound of microphone and rear it is analyzed and compares, with the test of realization to the loudspeaker of notebook computer.
3 employings of microphone testing apparatus are fixed on from the loudspeaker at the microphone 150mm place of notebook computer to be measured and test, at first the loudspeaker of microphone testing apparatus 3 are to the microphone playback of notebook computer to be measured, the microphone of notebook computer to be measured carries out radio reception, by the analysis of its radio reception effect and comparison being realized the test to the microphone of notebook computer.
Microphone paste lid arrangement 4 be positioned at notebook computer place the notebook computer to be measured on the tool 1 microphone under, for preventing that it is on the impact of test effect, its sectional area over against test horn is minimized, to reduce its reflection to sound in the test, adopt rotation and rectilinear motion to integrate mechanism and reach this requirement.Rotation integrates mechanism 42 with rectilinear motion and adopts linear electric motors 421 for power, carries out motion by the linkage rod slide block mechanism controlling organization gravity arm of force, and realizes estimating function.Such as Fig. 5, when mechanism during at initial position, its turning arm 422 is nearly 90 degree states in bottom and slide block 423, at mechanism's running cathetus motor 421 drive nuts 424 to left movement, nut 424 is by connecting rod 425 band movable slider 423 slippages left, this moment, turning arm 422 was done rotation and slippage along kidney slot and upper roller, when slide block 423 moves to when making turning arm 422 parallel with slide block 423 directions of motion, turning arm 422 stops the rotation, and along kidney slot with slide block together to left movement, such as Fig. 6, thus rotation and the rectilinear motion one operation function of realization integrated model.When turning arm 422 returned, mechanism realized with reverse motion.
During concrete the application, need manually will produce that the complete notebook computer of assembling takes off on the line, put on the notebook computer placement tool 1, connect data communication line, the affirmation successful connection is also opened test program, and equipment will be tested automatically subsequently.
In the test process at first horn testing device 2 drive test and move to test position with microphone 22, after feedback acknowledgment correctly arrives test position, the tested loudspeaker of notebook computer send the sound of setpoint frequency, the test microphone receives voice signal and is transferred to Test Host, by to signal imitation output waveform curve, and with the reference waveform of setting compare to judge whether by, after testing, horn testing device 2 is got back to original position.
Horn testing device 2 is got back to the sound that the loudspeaker of microphone testing apparatus 3 after the original position send setpoint frequency, the tested microphone of notebook computer receives sound and the signal conversion is outputed to Test Host, Test Host is by the analog signal output wavy curve, and compare with the reference waveform curve of setting, and judge whether test is passed through.
Microphone pastes lid arrangement 4 setting in motions subsequently, drive to paste and cover the rear malleation of pressure head 41 rotations on microphone to be measured, when pasting after microphone subsides cover on 41 pairs of notebook computers to be measured of pressure head cover tightly, loudspeaker on the microphone testing apparatus 3 send the sound of setpoint frequency again, microphone to be measured also receives and signal conversion and transmission sound again, Test Host receives signal and sunykatuib analysis, judges whether the microphone applying is qualified.After testing, microphone pastes lid arrangement 4 and gets back to original position.
After all tests step by step were finished, comprehensive above all test parameters carried out analysis-by-synthesis and judgement to the loudspeaker on the tested notebook computer and microphone, decide test result whether to pass through, and unsanctioned tested notebook computer is tested and reprocessed.
In sum, the notebook computer after this testing equipment is finished assembling carries out the test of acoustical behavior, test process automation, avoid the factors such as artificial and outside on the impact of test, improve product quality, to guarantee the stability of product performance after assembling is finished, promote experience and quality.
