Abstract
A method and apparatus for high speed and uniform manufacture and assembly of acoustical diaphragms having electrical conductor circuits applied thereto to frame components used with acoustic transducers wherein a web of diaphragm material having a plurality of spaced circuit carrying diaphragm sections applied thereto is moved relative to an applicator station wherein each section of the web of diaphragm material is placed under a predetermined tension and a frame component is bonded to the tensioned section, afterwhich the section of diaphragm material is severed from the web of diaphragm material.

A method of applying electrical circuit carrying diaphragms used in planar acoustic transducers to diaphragm supporting frame components wherein electrical circuits are applied in spaced relationship to an elongated web of diaphragm material to thereby define spaced diaphragm sections each having an electrical circuit with the web of diaphragm material being defined by elongated side edges and a central axis, the method comprising:
- conveying the web of diaphragm material to a diaphragm applicator station and aligning a diaphragm section relative to a frame component and applying a predetermined tension to the aligned diaphragm section of the web of diaphragm material and thereafter securing the tensioned diaphragm section to the frame component and severing the secured diaphragm section from the web of diaphragm material to thereby maintain the secured diaphragm section in a predetermined tension with respect to the frame component.
A method of applying electrical circuit carrying diaphragms used in planar acoustic transducers to diaphragm supporting frame components, the method comprising:
- a) providing an elongated web of the diaphragm material wherein the web has elongated side edges and an elongated central axis;
- b) forming a plurality of electrical conductor circuits in spaced relationship on the web of diaphragm material so as to define a plurality of diaphragm sections each having an electrical conductor circuit;
- c) conveying the web of diaphragm material to a diaphragm applicator station and aligning a diaphragm section with a frame component and applying a predetermined tension to the diaphragm section relative to at least one direction with respect to the central axis of the web of diaphragm material;
- and thereafter
- d) securing the tensioned diaphragm section to the frame component and severing the secured diaphragm section from the web of diaphragm material to thereby maintain the secured diaphragm section in predetermined tension with respect to the frame component.
An apparatus for applying electrical circuit carrying diaphragms used in planar acoustic transducers to diaphragm supporting frame components wherein the electrical circuits are applied in spaced relationship to an elongated web of diaphragm material such that the web of diaphragm material defines a plurality of diaphragm sections, each having an electrical circuit applied thereto, the apparatus comprising:
- means for conveying the web of diaphragm material from a feed station to a collection station,
- applicator means disposed between the feed station and the collection station through which the web of diaphragm material passes, said applicator means including first means for tensioning the diaphragm section in at least one direction with respect to an elongated axis of the web of diaphragm material,
- means for supporting at least one frame component and for engaging said at least one frame component with a diaphragm section of the web of diaphragm material being retained under tension by said means for tensioning and being adapted to retain pressure between the diaphragm section and the frame component until a bond is created therebetween to secure the diaphragm section to the frame component, and
- means for severing the diaphragm section from the web of diaphragm material.
A method of applying electrically conductive coated diaphragms used in electrostatic acoustic transducers to diaphragm supporting frame components wherein the conductive coating is applied to an elongated web of diaphragm material to thereby define a substantially continuously coated web of diaphragm material with the web of diaphragm material being defined by elongated side edges and a central axis, the method comprising:
- conveying the web of diaphragm material to a diaphragm applicator station and positioning the web relative to a frame component and applying a predetermined tension to the web of diaphragm material and thereafter securing a tensioned section of the web to the frame component and severing the secured section from the web of diaphragm material to thereby maintain the secured diaphragm section in a predetermined tension with respect to the frame component.
An apparatus for applying electrically conductive coated diaphragms used in electrostatic acoustic transducers to diaphragm supporting frame components wherein the conductive coating is applied to an elongated web of diaphragm material such that the web of diaphragm material defines a substantially continuous coated web of diaphragm material, the apparatus comprising:
- means for conveying the web of diaphragm material from a feed station to a collection station,
- applicator means disposed between the feed station and the collection station through which the web of diaphragm material passes, said applicator means including first means for tensioning the diaphragm section in at least one direction with respect to an elongated axis of the web of diaphragm material,
- means for supporting at least one frame component and for engaging said at least one frame component with a section of the web of diaphragm material being retained under tension by said means for tensioning and being adapted to retain pressure between the section and the frame component until a bond is created therebetween to secure the section to the frame component, and
- means for severing the section from the web of diaphragm material.
