Transducer having an armature arm split along its length

Claim 2

In a transducer having a case, a coil mounted in said case, a pair of spaced magnets mounted in the case, a first elongated arm having one end magnetically connected to said pair of spaced magnets, said first elongated arm is split along its length, a pair of bridges connected to the other end of said first elongated arm, and a second elongated arm having one end connected to the pair of bridges and having one portion movably positioned in the coil and another portion movably positioned between the spaced magnets.

Claim 3

A transducer as described in claim 1 wherein the first elongated arm has an enlarged portion at the end connected to the magnets.

Claim 4

A transducer as described in claim 1 wherein each of the bridges has each of its opposed ends formed integral with the respective elongated arms.

Claim 5

A transducer as described in claim 1 in which the first elongated arm has an enlarged portion at the end connected to the magnets and each of the bridges has each of its ends formed integral with each of the respective arms.

Claim 6

An armature reed for use in a transducer comprising, a substantially flat elongated arm adapted for positioning in a magnetic gap, a pair of opposed bridges formed integral with opposed edges of the elongated arm, and being substantially perpendicular to the elongated arm, and a second elongated arm substantially parallel to the first-mentioned elongated arm formed integral with the bridges, said second elongated arm is split along its length into two halves, whereby the bridges and the arms form a substantially rigid section connecting the arms.

Claim 7

An armature reed for use in a transducer comprising, a substantially flat elongated arm adapted for positioning in a magnetic gap, a pair of opposed bridges formed integral with opposed edges of the elongated arm, and being substantially perpendicular to the elongated arm, and a second elongated arm substantially parallel to the first-mentioned elongated arm formed integral with the bridges, said second elongated arm is split along its length into two halves, whereby the bridges and the arms form a substantially rigid section connecting the arms.

Claim 8

A transducer comprising, in combination, a case having a generally rectangular floor and a sidewall formed integral with the outer periphery of said floor, a bulkhead having a generally rectangular outline and having an edge formed integral with the outer periphery thereof mateably positioned within the sidewall, said edge having an annular flange extending outwardly therefrom and positioned in engagement with the sidewall to support the bulkhead on the sidewall, a cover having an acoustic aperture therein mounted on the annular flange in engagement with the edge of the bulkhead, a diaphragm mounted on the bulkhead within the cover, said bulkhead having an aperture contained therein, a coil mounted in said aperture and adhesively secured to the bulkhead, a generally U-shaped magnet support fixed to the bulkhead adjacent to said coil within said case, saId magnet support having a pair of feet adjacent to the edge for positioning relative to the bulkhead, a first magnet secured to the magnet support adjacent to the bulkhead, a second magnet secured to the bulkhead adjacent to the first magnet, a first elongated arm having a flared portion mounted on the magnet support, said first elongated arm being longitudinally split into two halves, a first bridge formed integral with one edge of the first elongated arm, a second bridge formed integral with the opposite edge of said elongated arm, and a second elongated arm having opposed edges formed integral with the bridges extending through the coil and positioned in the magnetic gap, wherein the ends of the elongated arms with the bridges form a substantially rigid section connecting the elongated arms.

Claim 9

A transducer comprising, in combination, a case having a generally rectangular floor and a sidewall formed integral with the outer periphery of said floor, a bulkhead having a generally rectangular outline and having an edge formed integral with the outer periphery thereof mateably positioned within the sidewall, said edge having an annular flange extending outwardly therefrom and positioned in engagement with the sidewall to support the bulkhead on the sidewall, a cover having an acoustic aperture therein mounted on the annular flange in engagement with the edge of the bulkhead, a diaphragm mounted on the bulkhead within the cover, said bulkhead having an aperture contained therein, a coil mounted in said aperture and adhesively secured to the bulkhead, a generally U-shaped magnet support fixed to the bulkhead adjacent to said coil within said case, saId magnet support having a pair of feet adjacent to the edge for positioning relative to the bulkhead, a first magnet secured to the magnet support adjacent to the bulkhead, a second magnet secured to the bulkhead adjacent to the first magnet, a first elongated arm having a flared portion mounted on the magnet support, said first elongated arm being longitudinally split into two halves, a first bridge formed integral with one edge of the first elongated arm, a second bridge formed integral with the opposite edge of said elongated arm, and a second elongated arm having opposed edges formed integral with the bridges extending through the coil and positioned in the magnetic gap, wherein the ends of the elongated arms with the bridges form a substantially rigid section connecting the elongated arms.
