Continuous load test of loudspeakers, speaker boxes, headphones, splitters, etc.
According to the test results, the rated input power of the tested product can be determined.
Inject noise into the loudspeaker to measure the sound pressure sensitivity (dB value) of the loudspeaker.
The frequency response curve of the loudspeaker can be measured by using the pink noise of the machine and the audio frequency spectrum analyzer.
Main features: The lowest resonant frequency Fo value is one of the important parameters of the loudspeaker. The 7117C can automatically measure the loudspeaker Fo value immediately without manual adjustment and display it in digital form. Moreover, the 7117C can set the upper and lower limits and automatically determine whether it is qualified/unqualified. It is very suitable for 100% quality inspection on the production line. 7117C is not only suitable for loudspeaker manufacturers, but also suitable for incoming inspection of loudspeakers in audio factories, multimedia factories, monitor factories, etc.
The lowest resonant frequency Fo value is searched automatically at high speed, and the reading time of Fo value is 1~1.5 seconds.
The upper and lower limits can be set, and the automatic judgment is qualified/unqualified. The search plus judgment time is only 0.3~0.7 seconds in total.
Digital display, accurate, no visual error.
Comply with ANSI and EIA standard test methods.
