Preferably, described detection method comprises the following steps:
(a) by audio amplifier workpiece from production line take out be positioned over detection instrument before;
B () utilizes detection instrument to be connected with polarity machine, detect the polarity of the left and right audio amplifier of audio amplifier workpiece, do not conform to if detect, audio amplifier workpiece will be removed and carries out the testing process of next audio amplifier workpiece, if it is qualified to detect, audio amplifier workpiece then enters next detecting step;
C () utilizes the signal that detection instrument is arranged passive switching device shifter that detection instrument is switched to and pure tone machine connection status;
D () utilizes detection instrument to be connected with pure tone machine, detect the pure tone of the left and right audio amplifier of audio amplifier workpiece, if detect defective, audio amplifier workpiece will be removed and skips following detecting step, if it is qualified to detect, then audio amplifier workpiece is put back to production line and flow to next detection operation.
Preferably, in described step (b) in step (d), the signal output part of described detection instrument is connected with the signal input part of the passive switching device shifter of signal, and two signal output parts of the passive switching device shifter of described signal connect the signal input part of polarity machine and the signal input part of pure tone machine respectively.
Preferably, the passive switching device shifter of described signal is foot switch.
Compared with prior art, the beneficial effect that the present invention has is:
The multimedia loudspeaker box polarity of improvement of the present invention and the detection method of pure tone, utilize the passive switching device shifter of the signal that detection instrument is arranged, select the signal data received by detection instrument to be first sent on polarity machine and carry out Check up polarity, be resent to pure tone machine and carry out pure tone detection.By the passive switching device shifter of signalization, achieve and first the Received signal strength of detection instrument is sent on polarity machine, be resent to pure tone machine, to realize Check up polarity and pure tone detection, a workman just can operate two test items, change in traditional detection operation, each workman can only carry out the operating process of a test item, can make tradition complete these two detect operation time 3 required workmans made 2 workmans into, number of workers decreases 1/3rd, production efficiency is improved, when keeping the operation beat of production line constant, decrease an operator, save labour cost.Further, polarity machine and pure tone machine are connected on a detection instrument simultaneously, decrease the use of a detection instrument, make production cost also corresponding minimizing.

Embodiment
Below in conjunction with embodiment, technical scheme of the present invention is described in further detail, but does not form any limitation of the invention.
With reference to shown in Fig. 1,2, the multimedia loudspeaker box polarity of a modification of the present invention and the detection method of pure tone, utilize the passive switching device shifter 2 of signal that detection instrument 1 is arranged, select the signal data received by detection instrument 1 to be first sent on polarity machine 3 and carry out Check up polarity, be resent to pure tone machine 4 and carry out pure tone detection.Described detection method comprises the following steps:
(a) by audio amplifier workpiece from production line take out be positioned over detection instrument 1 before, detect with detection instrument easy to use 1 pair of audio amplifier workpiece.
B () utilizes detection instrument 1 to be connected with polarity machine 3, detect the polarity of the left and right audio amplifier of audio amplifier workpiece.If detect defective, audio amplifier workpiece will be removed, and audio amplifier workpiece be returned production process and will carry out doing over again or directly underproof audio amplifier workpiece being carried out waste treatment, and skip following detecting step; If it is qualified to detect, audio amplifier workpiece then enters in the testing process of next process.
C () utilizes the signal passive switching device shifter 2 that detection instrument 1 is arranged that detection instrument 1 is switched to and pure tone machine 4 connection status, make audio amplifier workpiece enter next test item.
D () utilizes detection instrument 1 to be connected with pure tone machine 4, detect the pure tone of the left and right audio amplifier of audio amplifier workpiece.Do not conform to if detect, audio amplifier workpiece will be removed, and audio amplifier workpiece be returned production process and will carry out doing over again or directly underproof audio amplifier workpiece being carried out waste treatment, and carry out the testing process of next audio amplifier workpiece; If it is qualified to detect, then audio amplifier workpiece is put back to production line and flow to next detection operation.
The signal output part of described detection instrument 1 is connected with the signal input part of the passive switching device shifter 2 of signal, and two signal output parts of the passive switching device shifter 2 of described signal connect the signal input part of polarity machine 3 and the signal input part of pure tone machine 4 respectively.After the passive switching device shifter 2 of output signal entering signal of detection instrument 1, can by the passive switching device shifter 2 of manipulation signal, control to realize exporting the signal of two output ports, thus control detection instrument 1 to be sent to polarity machine 3 or pure tone machine 4, detect process operations to complete two.
The passive switching device shifter 2 of described signal is foot switch, in the process of whole detection, two hands of workman grip a detecting pen respectively and operate, if the words that the passive switching device shifter 2 of signal re-uses Non-follow control to switch, the detecting pen then needing workman to put down on hand could control, such operation can be inconvenient, and foot switch does not need workman to put down the detecting pen that both hands grip, the manipulation of convenient workman.In testing process, when workman tramps with one's feet foot switch, polarity machine 3 is opened, and just not by the interference of pure tone detection machine, carries out polarity test; When the pin of workman unclamps foot switch, pure tone machine 4 is opened, and starts to carry out pure tone detection, not by the interference of polarity test.
The multimedia loudspeaker box polarity of improvement of the present invention and the detection method of pure tone, by the passive switching device shifter 2 of signalization, achieve and first the Received signal strength of detection instrument 1 is sent on polarity machine 3, be resent to pure tone machine 4, to realize Check up polarity and pure tone detection, a workman just can operate two test items, change in traditional detection operation, each workman can only carry out the operating process of a test item, can make tradition complete these two detect operation time 3 required workmans made 2 workmans into, number of workers decreases 1/3rd, production efficiency is improved, when keeping the operation beat of production line constant, decrease an operator, save labour cost.Further, polarity machine 3 and pure tone machine 4 are connected on a detection instrument simultaneously, decrease the use of a detection instrument 1, make production cost also corresponding minimizing.
The foregoing is only preferred embodiment of the present invention, all do within the scope of the spirit and principles in the present invention any amendment, equivalent to replace and improvement etc., all should be included within protection scope of the present invention.
