摘要： PROBLEM TO BE SOLVED: To reduce vibration to be transmitted to a structure attached onto a loudspeaker driver.
SOLUTION: A vibration reducing apparatus is provided with a baffle subject to vibration, a first electroacoustical transducer characterized by a first mass seated in the baffle, and a second electroacoustical transducer mechanically connected to the first transducer or the baffle in the vicinity of the periphery of the first transducer. The rear sides of a diaphragms of the first and the second transducers are not connected to listening areas. The first and the second transducers are constituted and arranged to receive a common electrical signal, so that movable elements in the first and the second transducers move in phase opposition, in response to the common electrical signal to significantly reduce the vibrating force imparted to the baffle.
