Abstract
A piezoelectric transducer (100) may be achieved by mounting a piezoelectric bender (101) within a housing (102). Maximum resonation may be obtained by mounting the piezoelectric bender (101) on a single post (103). The housing (102) is constructed to have essentially the same geometry as the piezoelectric bender (101) and is separated by a predetermined distance (104). This predetermined distance (104) provides an acoustic impedance such that sound may resonate from the transducer.
