Abstract
A system and method for reducing baffle vibration includes balancing an inertial force generated by two or more moving diaphragms and balancing an acoustic pressure acting on a housing supporting the two or more moving diaphragms such that a net force acting on the baffle is substantially zero. The acoustic force acting on the housing may be balanced independently of the inertial force balance. In another configuration, the acoustic force acting on the housing may be balanced by a non-zero net inertial force.
