    摘要: Sonotrodes are used when examining substances on the basis of acoustic levitation. In order to obtain a reproducible measurement result or to extend the possible uses of devices of this kind, the respective sonotrode has to meet a whole range of requirements. Exact tuning of the frequency and clean interaction between the sonotrode and a frequency generator are particularly important. The present invention proposes that a sonic horn and a main body of the sonotrode are provided as different parts and, in this case, the sonic horn can be mounted on or in the main body in a specific manner, in particular for operation at low voltage in such a way that the amplitude or operating voltage remains below a comparatively low maximum low-voltage value, in particular 50 Vpp. The formation of heat can be prevented in this way. The present invention further relates to a control or production method for a sonotrode apparatus of this kind. In this case, it is respectively possible to extend the range of use and to improve the reproducibility or quality of the measurement results.

    摘要: A variable acoustic assembly comprising a housing and a one or more absorbing pads. The housing contains the one or more absorbing pads, a one or more doors, a one or more rear brackets, and a one or more hinges. The one or more doors attach to the one or more rear brackets with the one or more hinges. The one or more doors are configured to selectively open and selectively close between an open configuration and a closed configuration by rotating on the one or more hinges. The variable acoustic assembly having a closed width in the closed configuration and an open width in the open configuration. With the one or more doors in the open configuration, a portion of the one or more absorbing pads are exposed outside of the housing.

    摘要: A sound wave metamaterial amplifies a sound wave, and includes a plate. The plate has a plurality of sound wave guides passing through both surfaces of the plate and having a predetermined pattern. The sound wave guides are spaced apart from each other by a predetermined distance and face each other, with respect to a central point, a central axis or a central surface.
