There is presented a device for being secured to a structure. The device comprising a first portion comprising an element configured to impart mechanical waves to the structure upon application of a voltage and a second portion supporting the element and comprising a body. The body may be elastomeric, flexible, or both. The first and second portions are configured such that the element reacts against the second portion to generate mechanical waves at least partially within the structure. The body attenuates mechanical waves propagating from the first portion and away from the structure. A securing device for securing a mechanical wave generator to a structure and a system comprising the securing device are also presented. |
