Abstract (en)
[origin: DE4020881A1] A resonance oscillator comprises an active, e.g. disk-shaped, oscillator part (2) which is brought into contact, forming a couple oscillator, with a passive, relatively long oscillator part. This oscillator part, which basically determines the resonance frequency, consists of a variable-length solid column or liquid column (11) the length of which can be varied continuously in the direction of the sound vector in order to change the resonance frequency. The active oscillator part (2) is mounted on the base of an elongated resonance container (6) which contains the liquid that forms the liquid column (11). The length of the liquid column is varied by sliding a piston (5). The resonance container (6) is bounded by a corrosion-resistant, high-strength covering disk (7) of minimal thickness and is connected to an equalizing container (9) which receives the liquid displaced by the piston from the resonance container and returns the liquid to the resonance container.
