METHOD AND SYSTEM FOR REDUCING AUDIBLE AND/OR ELECTRICAL NOISE FROM ELECTRICALLY OR MECHANICALLY EXCITED CAPACITORS

摘要

Devices and methods are disclosed for reducing vibration and noise from capacitor devices. The device includes a circuit board, and first and second capacitor structures. The second capacitor structure has substantially the same properties as the first and is coupled to the opposite face of a supporting structure substantially opposite of the first capacitor structure. The first and second capacitor structures can receive substantially the same excitation signals, can be electrically connected in parallel or in series. The first and second capacitor structures can be discrete capacitors, capacitor layers, stacks or arrays of multiple capacitor devices, or other capacitor structures. Stacks of multiple capacitor devices can be arranged symmetrically about the supporting structure. Arrays of multiple capacitor devices can be arranged with offsetting capacitors on the opposite face of the supporting structure substantially opposite one another.
