Levered loudspeakers

摘要

A loudspeaker includes an acoustic diaphragm, a lever, and an oscillatory force source for driving the lever in oscillatory, rotary motion about a pivot axis. The loudspeaker also includes a connector that couples the lever to the acoustic diaphragm. The connector includes a first rotary joint that defines a first rotary axis that is fixedly attached to the acoustic diaphragm, a second rotary joint that defines a second rotary axis that is fixedly attached to the lever, and a linkage coupling the first and second rotary joints. The connector allows for rotational and translational movement of the lever and the diaphragm relative to each other.

1. A loudspeaker comprising:
A.) an acoustic diaphragm; B.) a lever; C.) an oscillatory force source for driving the lever in oscillatory, rotary motion about a pivot axis; and D.) a connector coupling the lever to the acoustic diaphragm, the connector comprising:
i.) a first rotary joint defining a first rotary axis fixedly attached to the acoustic diaphragm,ii.) a second rotary joint defining a second rotary axis fixedly attached to the lever, andiii.) a linkage coupling the first and second rotary joints, wherein the connector allows for rotational and translational movement of the lever and the diaphragm relative to each other, wherein the second rotary joint comprises a tab including a mounting hole for receiving a fastener for securing a central portion of the second rotary joint to the lever.
