Foam patches to stabilise sound components

7 September 2016 Analogue, Mixed Signal, LSI

To complement its range of buzzers and transducers, alarms and sirens, and piezoceramic speakers and amplifiers, Sonitron offers a foam patch option to provide extra mechanical and acoustic stability to its sound components in applications for rugged or difficult environment.

Available specifically for the SMA(T), SMB, SCS and SMAC product series and denoted by the –FP part number suffix, the patches are made out of double coated urethane foam tape. The foam patch option makes the parts very easy to stick and secure for precise and stable mounting, especially when SMD sound components are used in applications that have to withstand high vibrations.

The shape of the foam patch is optimised according to the particular Sonitron sound component, while the material, temperature, strength, adhesive and thickness are chosen for optimum suitability. These patches effectively cancel unwanted disturbances between the PCB panel and the housing of the sound component, resulting in better acoustic sound stability.
