Patent ID: 7366317

Claim:
A transducer comprising: a first movable member, the first movable member coupled to a linkage, the linkage coupled to a second movable member, the linkage comprising an upper portion comprising a first diagonal member and a second diagonal member, the first and second diagonal members each being coupled to the second movable member, a lower portion comprising a third diagonal member and a fourth diagonal member, the third and fourth diagonal members being coupled to the first movable member by a lower horizontal span segment, the third diagonal member also being coupled to the first diagonal member at a first vertex and the fourth diagonal member also being coupled to the second diagonal member at a second vertex, the upper portion having an upper height defined by a shortest distance between a straight line extending between the first and second vertices and a point where the first and second diagonal members are coupled to the second movable member, the lower portion having a lower height defined by a shortest distance between the line between the first and second vertices and a point along the lower horizontal span segment, the upper height being different than the lower height, the first and second vertices are coupled to a housing by first and second legs respectively that are non-parallel to each other as they extend from the first and second vertices and towards the housing.
