Abstract

In this study, deployable cylinders with bellows-like patterns are used to change the neck length of Helmholtz resonator. The cylinders are quasi-rigid foldable and constructed by assembling flat, rigid quadrilateral plates. Acoustic computation revealed that the proposed resonator with a deployable neck worked effectively to attenuate noise at a resonant frequency. Furthermore, we discuss that the proposed resonator was able to cover low frequency range, because the neck length changed reciprocally to the cross-sectional area and the resonant frequency reached zero in theory according to the geometrical configuration of the cylinder.
