Abstract

Un dispositivo trasduttore piezoelettrico con una piezomembrana accoppiata mediante un perno centrale ad una piastra di carico a sua volta vincolata sulla circonferenza esterna viene impiegato per costituire un avvisatore acustico in cui la piastra di carico è parte integrante dell'involucro dell'avvisatore.(FIGG. 1 e 5)
