Creating Sustained Tones with the Cicada's Rapid Sequential Buckling Mechanism
نویسندگان
چکیده
The cicada uses a rapid sequence of buckling ribs to initiate and sustain vibrations in its tymbal plate (the primary mechanical resonator in the cicada’s sound production system). The tymbalimba, a music controller based on this same mechanism, has a row of 4 convex aluminum ribs (as on the cicada’s tymbal) arranged much like the keys on a calimba. Each rib is spring loaded and capable of snapping down into a V-shape (a motion referred to as buckling), under the downward force of the user’s finger. This energy generated by the buckling motion is measured by an accelerometer located under each rib and used as the input to a physical model.

متن کاملPulse sound generation, anterior swim bladder buckling and associated muscle activity in the pyramid butterflyfish, Hemitaurichthys polylepis.
Acoustic behaviors are widespread among diverse fish taxa but mechanisms of sound production are known from relatively few species, vary widely and convergent mechanisms are poorly known. We examined the sound production mechanism in the pyramid butterflyfish, Hemitaurichthys polylepis, a member of the socially and ecologically diverse reef fish family Chaetodontidae. In the field, fish produce...
متن کاملThe Importance of Amplitude Envelope: Surveying the Temporal Structure of Sounds in Perceptual Research
Our lab’s research has repeatedly documented significant differences in the outcomes of perception experiments using flat (i.e. sustained) vs. percussive (i.e. decaying) tones [1, 2]. Some of these findings contrast with wellestablished theories and models, and we suspect this discrepancy stems from a traditional focus on flat tones in psychophysical research on auditory perception. To explore ...
متن کاملIn situ Mechanical Testing Reveals Periodic Buckle Nucleation and Propagation in Carbon Nanotube Bundles
Uniaxial compression studies are performed on 50-mm-diameter bundles of nominally vertical, intertwined carbon nanotubes grown via chemical vapor deposition from a photolithographically defined catalyst. The inhomogeneous microstructure is examined, demonstrating density and tube orientation gradients, believed to play a role in the unique periodic buckling deformation mechanism. Through in sit...
متن کاملPipeline upheaval buckling in clayey backfill using numerical analysis
Offshore pipelines used for oil and gas transportation are often buried to avoid damage from fishing activities and to provide thermal insulation. Thermal expansion and contraction of the pipeline during operation can lead to lateral or upheaval buckling. A safe buried pipeline design must take into account a reliable evaluation of soil uplift resistance and pipe embedment depth. While the cost...
