Journal, No: NEW ZEALAND THE PATENTS ACT , 1953 COMPLETE SPECIFICATION "TRANSDUCER FRAME ASSEMBLY" WE, INTERNATIONAL STANDARD ELECTRIC CORPORATION, a Corporation of the State of Delaware, United States of America, of 320 Park Avenue, New York 22, New York, United States of America, hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: 206901 This invention relates to a method of and apparatus for the assembly of a multi-component device.
According to the invention there is provided a method of assembling a device, which includes one or more components located inside a two or more piece structure, in which the internal component or components is or are assembled within a shell which forms part of the structure and are accurately located therein, in which a cover member which also forms part of the structure is provided for the device which cover member has studs which extend inwardly when the cover member is in use, and in which the assembly involves the steps of placing the cover member over the shell with the internal component or components in position, the studs then being in engagement with the inside of the shell and with at least one internally-located component, and subjecting the cover member to ultrasonic vibrations and pressure, which causes the studs to deform due to the pressure and to the effect of the ultrasonic vibrations, which deformation causes the studs to collapse so that the cover member is moved inwardly of the device and the studs collapse around the shell and the internally-located component or components.
An example of the sort of device which may be assembled by the above method is an electro-acoustic transducer, and the invention is further described as applied to the assembly of a moving coil transducer such as described in Application N.Z. PATENT OFFICE 2 2 APR 1986 RECEIVED 206901 No. 203,080.
Thus the invention also provides a method of assembling an electro-acoustic transducer assembly, which includes a magnet assembly accurately located within a shell which forms part of a two-piece structure, in which the structure also includes a cover member having studs which extend inwardly when the cover member is in use, and in which the assembly involves the steps of placing the cover member over the shell with the studs each in engagement with the inside of the shell and with part of the magnet assembly, and subjecting the cover member to ultrasonic vibrations and to pressure as a result of which the studs deform due to the pressure and to the effect of the ultrasonic vibrations, which deformation causes the studs to collapse so that the cover member is moved inwardly of the device and the studs collapse around the shell and the magnet assembly to secure the magnet assembly in place within the shell.
An embodiment of the invention will now be described with reference to the accompanying drawing, which shows in Figs. 1 and 2 two stages of the novel assembly technique.
Referring now to the drawing, Fig. 1 is a cross section of a circular component assembly, in the present case an electro-acoustic transducer. An outer plastics shell 1, supports three components 2, 3 and 4, which have been prepo-sitioned with a controlled gap 5. In the case of the trans- 2069 0 I ducer, these three components are the transducer's magnetic circuit, these being a ring-shaped magnet 2, disc-shaped pole-piece 3 and yoke plus polepiece 4. The controlled gap 5 receives the moving coil of the transducer. A plastics cover 5 6, has six circular studs such as 7, moulded integral with it.
To complete the assembly, the above components are supported on a solid base 8, and pressure and ultrasonic vibrations are applied thereto by means of a transducer 9. This causes the studs 7 to deform due to the vibration and to col ipse 10 around the components 2 and 4, thus retaining them in the pre set position. At the same time an energy concentrator 11 of a suitable plastics material (Fig. 1) fuses into the cover and completes the seal.
After the assembly described above, the transducer is 15 completed by assembly to it the diaphragm and moving coil, plus the front cover. Thus the final product in the present example is a transducer of the type described in the above application. Although the method has been described as applied to the assembly of an electro-acoustic transducer, it should be 20 noted that it is not so limited. Further, the number of compo nents involved is not critical; any number of components can be secured. Further, the plastics parts, such as the cover 6, can be any shape. The studs such as 7, need not be circular in cross-section and can be of any number. The only critical 25 factor is that their total' strength is significantly less than the stength of the main structure.

Claims (4)

206901 What we claim is:-
1. A method of assembling a device, which includes one or more components located inside a two or more piece structure, in which the Internal component or components is or are assembled within a shell which forms part of the structure and are accurately located therein, in which a cover member which also forms part of the structure is provided for the device, which cover member has studs which extend inwardly when the cover member is in use, and in which the assembly involves the steps of placing the cover member over the shell with the Internal component or components in position, the studs then being in engagement with the inside of the shell and with at least one internally-located component, and subjecting the cover member to ultrasonic vibrations and pressure, which causes the studs to deform due to the pressure and to the effect of the ultrasonic vibrations, which deformation causes the studs to collapse so that the cover member is moved inwardly of the device and the studs collapse around the shell and the internally-located component or components.
2. A method of assembling an electro-acoustic transducer assembly, which includes a magnet assembly accurately located within a shell which forms part of a two-piece structure, in which the structure also includes a cover member having studs which extend inwardly when the cover member is in use, and in which the assembly involves the steps of placing the cover member over the shell with the studs each in engagement with the inside of the shell and with part of the magnet assembly, and subjecting the cover member l. PATENT OFFICE 2 2 APR 1986 206901 to ultrasonic vibrations and to pressure as a result of which the studs deform due to the pressure and to the effect of the ultrasonic vibrations, which deformation causes the studs to collapse so that the cover member is moved inwardly of the device and the studs collapse around the shell and the magnet assembly to secure the magnet assembly in place within the shell.
3. A method of assembling an electro-acoustic transducer assembly, substantially as described with reference to the accompanying drawings.
4. An electro-acoustic transducer assembly assembled by the method of any of claims 1, 2 or 3. INTERNATIONAL STANDARD ELECTRIC CORPORATION P.M. Conrick Authorized Agent P5/1/1466 i N.2. PATENT OFF !HF I - ~ 2 2 APR 1986
