VOICE COIL |
| 摘要 |
A voice coil adapted for being applied in a miniature electricity-powered loudspeaker includes a plurality of coils formed by winding an enameled wire. The coils are stacked up and down to show a hollow multilayer structure with an accommodating space being formed therein. Each coil has two parallel and spaced straight-line segments, and two symmetrical arc segments oppositely connected between the two straight-line segments. A middle of the arc segment is arched outward. A radius of each arc segment is greater than one half of a spacing distance between the two straight-line segments. |
