We present the Bistable Resonator Cymbal, a type of actuated acoustic instrument which augments a conventional cymbal with feedback-induced resonance. The system largely employs standard, commercially-available sound reinforcement and signal processing hardware and software, and no permanent modifications to the cymbal are needed. Several types of cymbals may be used, each capable of producing ...

An ultrasonic orthopaedic surgical device is presented, where the ultrasonic actuation relies on a modification of the classical cymbal transducer. All current devices consist of a Langevin ultrasonic transducer with a tuned cutting blade attached, where resonance is required to provide sufficient vibrational amplitude to cut bone. However, this requirement restricts the geometry and offers lit...

Valve piezoelectric pumps usually have larger flow rate than that of valveless ones. However, the traditional cantilever valve easily induces stress concentration which impacts the reliability of pumps. Therefore, a cymbal‐shaped slotted check valve is proposed to be applied in a piezoelectric pump in order to reduce the stress concentration of the valve and thus improve the reliability of the ...

A class V cymbal flextensional transducer is composed of a piezoceramic disc sandwiched between two cymbal-shaped shell endcaps. Depending on the type of piezoceramic, there exists a maximum voltage that can be reached without depolarisation, but also, at higher voltage levels, amplitude saturation can occur. In addition, there is a restriction imposed by the mechanical strength of the bonding ...

This paper is concerned with the extension of existing nonlinear physical modeling sound synthesis cymbals to that involving dynamics washers supporting center and sticks/mallets striking cymbals. The body a cymbal physically modeled as shallow spherical shell its governing equation discretized in space using finite difference method, was implemented research. In addition, washer, related suppo...

This paper reports the performance differences in the receiving sensitivity and band width of Class V flex tensional transducers (Cymbals) both in-air and in-water by varying the design parameters. Cymbal elements with device diameter 8mm and 13mm with optimum designs achieved using finite element software ATILA is presented. The in-air and underwater characteristics of such transducers are des...

The transient acoustic dynamics of a splash cymbal are investigated via the Finite Element Method-Boundary Method. Real three-dimensional motion data recorded from interaction drummer–drumstick–cymbal provide initial and loading conditions to simulated drumstick–cymbal Models. Progressively intensified free strokes used as for both experiment simulation. velocity values moving drumstick in vari...

The class V cymbal is a flextensional transducer commonly used in low-power ultrasonic applications. The resonance frequency of the transducer can be tailored by the choice of end-cap and driver materials, and the dimensions of the end-caps. The cymbal transducer has one significant limitation which restricts the operational vibration amplitude of the device. This is the limit imposed by the me...

it is the instructor’s responsibility to instill a positive attitude and set high expectations for all members, while helping students grow and become better musicians. If difficulty is the modern measuring stick for superiority, then one can certainly argue that multi-tenors are the most challenging instrument to play, while others will say the bass drum requires the most demanding skill. Alth...
