Elastomeric Torsion Bushings for Levered Loudspeakers |
| 摘要 |
A loudspeaker includes an acoustic diaphragm, an oscillatory force source, a lever coupling the oscillatory force source to the acoustic diaphragm, and a pivot coupled to the lever such that the lever moves in an arcuate path about the pivot when the oscillatory force source applies a force to the lever. The pivot includes at least one torsion bushing. The at least one torsion bushing includes a first member, a second member coupled to the lever and movable relative to the first member, and an elastomeric member coupling the first member to the second member. |

1. A loudspeaker comprising:
an acoustic diaphragm; an oscillatory force source; a lever coupling the oscillatory force source to the acoustic diaphragm; and a pivot coupled to the lever such that the lever moves in an arcuate path about the pivot when the oscillatory force source applies a force to the lever, wherein the pivot comprises at least one torsion bushing, the at least one torsion bushing comprising:
a first member;a second member coupled to the lever and movable relative to the first member; andan elastomeric member coupling the first member to the second member. |
