A support arrangement for readily mounting the diaphragm of a piezoelectric transducer on a desired node ring, the diaphragm having coaxially mounted thereon a circular piezoceramic element having a diameter substantially the same as that of the node ring. A substantially rigid support member and a clamping spider have annular means thereon also having the same diameter as that of the node ring such that the periphery of the piezoceramic element acts as a guide means by cooperating with one of the annular mounting means to assure coaxial alignment of the diaphragm, the support members, and the clamping spider. The support members and the clamping spider are snapped together to rapidly and accurately provide the diaphragm mounting on the desired node ring.

DETAILED DESCRIPTION It is therefore an object of the invention to provide a mounting arrangement for piezoelectric transducers that simplifies assembly of the transducer.
Another object of the invention is to provide a mounting arrangement for piezoelectric transducers that facilitates positioning of the flexible diaphragm such that it is supported on a desired node ring.
Yet another object is to provide an improved piezoelectric transducer assembly that can be rapidly and easily assembled with a high degree of accuracy in the positioning of the flexible diaphragm relative to its support elements.
Briefly stated, in carrying out the invention in one form, a sound generating device includes a flexible diaphragm having a central axis, a substantially rigid support member having an annular ridge projecting therefrom into contact with a first side of the diaphragm, a clamping spider contacting the other side of the diaphragm, interconnecting means between the rigid support member and said clamping spider for causing the diaphragm to be supported between the support member and the spider, and means for vibrating the diaphragm to produce sound.
More particularly, the support member has an annular ridge projecting axially from the support member into contact with the diaphragm, the diameter of the annular ridge being equal to the diameter of a node circle of vibration of the diaphragm.
The clamping spider has a hub portion and a plurality of resilient leg portions extending radially outwardly of the hub portion.
Each of the leg portions has at least one support element projecting axially therefrom into contact with the diaphragm, the support elements being disposed in a circular array having the same diameter as the annular ridge.
The interconnecting means joins the support member and each of the leg portions radially outwardly of the diaphragm, and the interconnecting means resiliently biases the leg portions toward the diaphragm to support the diaphragm between the annular ridge and the support elements
