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.

An improved speaker voice coil structure, comprising:
- a bobbin;
- a first voice coil, wound around said bobbin, and having a first terminal and a second terminal;
- a second voice coil, wound around said first voice coil, and having a third terminal and a fourth terminal;
- and
- a third voice coil, wound around said second voice coil, and having a fifth terminal and a sixth terminal, wherein said first terminal, said second terminal, said third terminal, said fourth terminal, said fifth terminal, and said sixth terminal are approximately evenly separated with an angular distance seen from the center of said bobbin.
An improved speaker voice coil structure, comprising:
- a bobbin;
- a first voice coil, wound around said bobbin, and having a first terminal and a second terminal;
- a second voice coil, wound around said first voice coil, and having a third terminal and a fourth terminal, wherein both of the angle between said third terminal and said first terminal seen from the center of said bobbin, and the angle between said fourth terminal and said second terminal seen from the center of said bobbin are equal to a first angle;
- and
- a third voice coil, wound around said second voice coil, and having a fifth terminal and a sixth terminal, wherein both of the angle between said fifth terminal and said third terminal seen from the center of said bobbin, and the angle between said sixth terminal and said fourth terminal seen from the center of said bobbin are equal to a second angle.
