Non-directional transducer |
| 摘要 |
A transducer for the creation of acoustic energy omni directionally in a horizontal plane. The transducer includes a base plate, the base plate supporting a centrally located voice coil motor assembly and a hemi-toroidal diaphragm having a proximal edge and a distal edge. The proximal edge is appended to the centrally located voice coil motor assembly and the distal edge is appended to the base plate. |

1. A transducer, comprising:
a hemi-toroidal diaphragm with a proximal edge and a distal edge, encompassing a center area without a diaphragm; and a voice coil motor assembly centrally located, wherein said proximal edge of said diaphragm is appended to said voice coil motor assembly; wherein said diaphragm bends to generate bending-wave acoustic energy, and does not act pistonically. |
