57 Abstract AB [DE] Die Erfindung betrifft einen robusten, preiswerten Schwingungserreger, dessen Schwingsystem gegen Verdrehen und Herausreißen gesichert ist, der gekühlt und in Amplitude, Kraft und Frequenz regelbar ist.$A Der Schwingungserreger ist in beliebiger Lage, in Unter- oder Überdruck sowie in Flüssigkeiten zu betreiben.
[EN] The vibration test unit has a robust construction to prevent self-destruction or rotation of oscillating components, guaranteeing control of oscillation parameters. Optimum temp. control of the magnetic and oscillation system is achieved and the interior can be subjected to positive or negative pressure. A spool through which current-flows, is free to vibrate inside a magnet and is attached to a polymeric membrane e.g. natural or silicone rubber, possible fibre reinforced. A piston passing through a bore in the magnetic connected to the vibration transfer system and prevents sideways movement leading to damage to the vibration system. The spool is supported on a non-magnetic carrier, e.g. aluminium or metal-coated reinforced plastic. USE/ADVANTAGE - The appts. is used to vibration test components, e.g. loudspeakers and electronics, is water and dust tight, has a secure oscillating system, can be cooled or heated and has a variable internal pressure.
