Description
Technical field
The utility model relates to microphone tester, particularly a kind of tester of silicon microphone on wiring board.
Background technology
The silicon microphone of general cell phone system is tested after the installation of client streamline again, run into defective products need tear machine open and reprocess or change flat cable, if and drop into will carry out testing also needing first to load after mobile phone plug receptacle restarts recorder program typing one section of sound before streamline at the wiring board posting silicon microphone and reset, judge the quality of the wiring board posting silicon microphone with this, above-mentioned two kinds of methods all also exist the problem that testing efficiency is low, operate inconvenience or generation excess loss.
Summary of the invention
In order to overcome above-mentioned existing issue, the utility model provides a kind ofly has flexibility, the tester for wiring board silicon microphone easy to use.
The technical solution of the utility model is: a kind of tester for wiring board silicon microphone, comprise measurement jig, control system, test cell, control button, LED display lamp, it is characterized in that: described test cell comprises measurement jig socket, channel asynchronised handover module, signal amplifier and earphone external-connected port, described control system is connecting test unit respectively, control button and LED display lamp, measurement jig is connected with measurement jig socket, measurement jig socket connecting channel asynchronised handover module, channel asynchronised handover Module connection signal amplifier, signal amplifier frames connecting with headphone external-connected port, described channel asynchronised handover module is also connected with control system.
Described measurement jig is in order to the location to tested test plate (panel), and measurement jig can be the test machine of different model, preferably, this measurement jig is manual pressing-type, on the corresponding testing weld pad of tested test plate (panel), make tested test plate (panel) be fixed on measurement jig with spring pinprick, flexibility is strong, convenient mobile.
Described channel asynchronised handover module is 8 passage asynchronised handover modules, can take turns 8 signals of the tested plate of current test.
Described signal amplifier is the signal amplifier of 200 times of gains.
Described control button is used for speed and the switch mode of control channel switching, and switch mode is manually or automatically.
Described LED display lamp is used for the switching state of simultaneous display channel.
Described control system is single-chip computer control system.
The beneficial effects of the utility model are: the utility model adopts novel test cell structure, and structure is simple, and flexibility is strong, and simple to operate, testing efficiency is high, and the test board for different model only needs to change measurement jig.
Accompanying drawing explanation
Fig. 1 is originally structured flowchart of the present utility model.
In figure, 1-measurement jig, 2-control system, 3-measurement jig socket, 4-channel asynchronised handover module, 5-signal amplifier, 6-controls button, 7-LED display lamp, 8-earphone external-connected port.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, a kind of tester for wiring board silicon microphone, comprise measurement jig 1, control system 2, measurement jig socket 3, channel asynchronised handover module 4, signal amplifier 5, earphone external-connected port 8, control button 6 and LED display lamp 7, described control system 2 is connecting test tool socket 3 respectively, channel asynchronised handover module 4, control button 6 and LED display lamp 7, measurement jig 1 is connected with measurement jig socket 3, measurement jig socket 3 connecting channel asynchronised handover module 4, channel asynchronised handover module 4 connection signal amplifier 5, signal amplifier 5 frames connecting with headphone external-connected port 8, earphone external-connected port 8 is connected with earphone.
Described measurement jig 1 is in order to the location to tested test plate (panel), measurement jig 1 can be the test machine of different model, preferably, this measurement jig is manual pressing-type, on the corresponding testing weld pad of tested test plate (panel), tested test plate (panel) is made to be fixed on measurement jig with spring pinprick, flexibility is strong, convenient mobile.
Described channel asynchronised handover module 4 is 8 passage asynchronised handover modules, can take turns 8 signals that the tested plate of current test sends.
Described signal amplifier 5 is the signal amplifier of 200 times of gains.
The speed that described control button 6 switches for control channel and switch mode, switch mode is manually or automatically.
Described LED display lamp 7 is for the switching state of simultaneous display channel.
Described control system 2 is single-chip computer control system.
Test philosophy of the present utility model is as follows: tested test plate (panel) is positioned on measurement jig 1, after measurement jig 1 connecting test tool plug 3, tested test plate (panel) sends silicon wheat signal, control system 2 enters channel automatic switchover mode, signal switches automatically in turn through 8 passage asynchronised handover modules 4, via signal amplifier 5, signal is amplified 200 times again, finally output to earphone by earphone external-connected port 8, the voice signal that each silicon wheat collects can be heard respectively from earphone, simultaneously corresponding channel display lamp meeting two, for judging present channel, what can hear ambient sound is non-defective unit, what do not have sound or only have noise is defective products.
This tester power-supply service 5V, can facilitate on computers, on charger or power taking in charger baby; 8 passage asynchronised handover modules adopt 74HC4051, and it is low that it switches pressure drop, and switch speed is fast, and the frequency of switching is controlled by SCM system.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
