ABSTRACT:
This invention concerns a low frequency, high energy output electroacoustic transducer. It utilizes a vibratory unit formed of a stack of hollow ceramic cylinders about which is fitted a resilient metal sleeve. The metal sleeve is tensioned outwardly during assembly of the unit so that, upon relaxation, it will fit about the stack as tightly as possible. To further make the stack and sleeve integral, a bonding material is placed between the two. A gap in the sleeve serves as a cutting guide for gapping the stack. Air backing is used to further increase the energy output of the transducer.
