Baffle vibration reducing |
摘要 |
An apparatus for reducing baffle vibration includes a baffle that is subject to vibration. A first transducer that is seated in the baffle includes a first diaphragm that is acoustically coupled to a listening area in a vehicle and also acoustically coupled to a cavity in the vehicle. A first input signal applied to the first transducer causes the first diaphragm to move in a first direction, thereby generating an acoustic output. A second transducer is mechanically coupled to the first transducer. The second transducer includes a second diaphragm that is acoustically coupled to the first diaphragm and also acoustically coupled to the listening area. A second input signal applied to the second transducer causes the second diaphragm to move in a second direction that is substantially opposite to the first direction to reduce a vibration imparted to the baffle while substantially maintaining the acoustic output.
