Abstract
Official abstract text for this publication.
There is disclosed a transducer apparatus for acoustic communications through a substrate at a predetermined center frequency, the apparatus comprising:—an active piezoelectric element for generating an acoustic signal; an intermediate layer, having a surface for accommodating the piezoelectric element, and having a first array of protrusions on a surface opposite the surface for accommodating the piezoelectric element; and a second array of protrusions at the substrate, wherein the active piezoelectric element is mounted onto the intermediate layer, and the intermediate layer is secured in position relative to the substrate such that the first array of protrusions faces the second array of protrusions such that the acoustic signal may propagate through the first and second arrays. There are further disclosed a method of mounting such an apparatus and a plate suitable for use in the transducer apparatus.
First claim
Opening claim text (preview).
The invention claimed is: 1. A transducer apparatus for acoustic communications through a substrate at a predetermined centre frequency, the apparatus comprising: a piezoelectric element for generating an acoustic signal; a carrier plate, having a first surface for accommodating the piezoelectric element, and having a first array of protrusions on a second surface opposite the first surface; and a second array of protrusions at a surface of the substrate, wherein the piezoel…
