  • Speaker voice coil structure having at least three coils
    Patent number: 8374380
    Abstract: An improved speaker voice coil structure, the structure including: a bobbin; a first voice coil, wound around the bobbin and having a first terminal and a second terminal; a second voice coil, wound around the first voice coil and having a third terminal and a fourth terminal; and a third voice coil, wound around the second voice coil and having a fifth terminal and a sixth terminal. The improved voice coil structure thereby provides multiple optional connection terminals—from different layers with different values of impedance—for an input signal.
