Abstract

A vibration testing system using acoustical waves having a testing unit including a main enclosure defining a main acoustical cavity and having a baffle provided with a main opening which is aligned with a set of acoustical insulation bands receiving an article to be tested that are clamped on a fixture secured to the baffle, so that the main opening is substantially closed by the article and the acoustical insulation bands. The apparatus includes a main acoustical source comprising a main acoustical transducer such as a loudspeaker which is acoustically coupled to the main acoustical cavity, and a subsystem for driving the loudspeaker which generates acoustical waves imparting vibration to the article accordingly. The apparatus preferably also includes a further acoustical source in the form of one or more further loudspeakers facing the main loudspeaker with the baffle extending therebetween, the further loudspeakers showing complementary frequency operating ranges.
