Sandwich-Type Woofer with Two Sound Wave Propagation Directions and a Magnetic-Looped Device Thereof
First Claim
1. A sandwich-type woofer with two sound wave propagation directions, comprising:
- a first magnetic-conducting plate unit;
a second magnetic-conducting plate unit;
a magnet unit sandwiched between the first and second magnetic-conducting plate units;
a coil frame extending through the first magnetic-conducting plate unit, the magnet unit and the second magnetic-conducting plate unit, and having a first end and a second end;
a first vibrating unit disposed at the first end of the coil frame;
a second vibrating unit disposed at the second end of the coil frame;
a first coil arranged on a portion of the coil frame corresponding to the first magnetic-conducting plate unit; and
a second coil arranged on another portion of the coil frame corresponding to the second magnetic-conducting plate unit.

Abstract
A sandwich-type woofer with two sound wave propagation directions includes a first magnetic-conducting plate unit, a second magnetic-conducting plate unit, a magnet unit, a coil frame, a first vibrating unit, a second vibrating unit, a first coil and a second coil. The magnet unit is sandwiched between the first and second magnetic-conducting plate units. The coil frame extends through the first and second magnetic-conducting plate units and the magnet unit, and has first and second ends. The first vibrating unit is disposed at the first end of the coil frame and the second vibrating unit is disposed at the second end of the coil frame. The first coil is arranged on a portion of the coil frame corresponding to the first magnetic-conducting plate unit and the second coil is arranged on another portion of the coil frame corresponding to the second magnetic-conducting plate unit.
