内容記述 |
The resistance of the resonator neck determines the sound dissipation and the sharpness of resonance of a resonator, while its cavity volume, sectional area and length ofthe resonator neck determine its resonant frequency. Out of these control parameters, the resonator neck resistance is the most problematic to adjust. It is desirable to able to adjust the sound dissipation without modifying the resonant frequency.
To realize a resistance controller having this property, a spiral spring was installed in a neck of circular cross-section. The gap width between the spring plates could be adjusted by twisting the spiral core shaft. The resistance of the neck aperture was expected to be inversely proportional to the gap width. Prototypes of spiral-spring mounted necks were produced and were tested by conducting experiments using the impedance-tube twomicrophone position method.
Consequently, it was confirmed that each of the spiral-spring mounted necks had a variable resistance sufficient for sound dissipation control and had a resistance that was monotone decreasing function of the spring-plate gap width. Varying the gap width had little effect on the effective sectional area and the effective length of the neck and hence did not modify the resonant frequency much. |
