ABSTRACT:
A molded rubber tubular member includes a grommet-like flange at its open end for permitting the structure to be attached to a panel. A recessed nest portion is provided at the opposite end of the tubular member into which is inserted a transducer whose diaphragm serves as a closure at the end of the tubular member. The assembly serves as a flexible shock mount for the transducer and also as an acoustic amplifier which increases the acoustic sensitivity of the transducer by 10 to 20 dB in a selective frequency band within the audible range.
