AB  - This paper addresses the problem of the spatial distribution of sound pressure generated by an annular membrane. A generalized theoretical approach will be developed in order to predetermine the sound field radiation of a disc or ring shaped diaphragm, placed in a rigid infinite baffle. Because no assumption is made regarding the observing point, this generalized method is able to predict the acoustic pressure not only in the far field region but also in near field. Results demonstrate the superiority of the co-incident ring distribution compared to the traditional discrete distribution of discs. A new transducer based on concentric ring and disc especially designed to respect this coincident criterion will be introduced.
