RESONATOR MIT GLEICHMAESSIGER AUSGANGSSCHWINGUNGSAMPLITUDE

摘要

The invention concerns resonators of rectangular or blade like configuration providing substantially uniform motional output along the output surface. The improvement is achieved by disposing the change in cross-sectional area for producing increased motional amplitude at the output surface in relation to the nodal region of the resonator in such a manner as to cause the lateral portions of the resonator to exhibit a greater motional amplitude gain than that of the central portion.
