  • Baffle vibration reducing
    Patent number: 7551749
    Abstract: An electro-acoustic transducer includes a magnet assembly having a first magnetic flux gap and a second magnetic flux gap. A first voice coil is positioned in the first magnetic flux gap. A first diaphragm is mechanically coupled to the first voice coil and to a frame. The first voice coil moves the first diaphragm in a first direction in response to receiving a first input signal. A second voice coil is positioned in the second magnetic flux gap. A second diaphragm is mechanically coupled to the second voice coil and to the frame. The second voice coil moves the second diaphragm in a second direction that is substantially opposite to the first direction in response to receiving a second input signal. The movement of the second diaphragm reduces a vibration imparted to the frame by the movement of the first diaphragm.
