Abstract

PURPOSE:To fit a voice coil accurately by incorporating a flat diaphragm during centering without pulling out a voice coil centering jig and then fixing the jig in a speaker main body. CONSTITUTION:Centering of a voice coil 2 is executed with use of a voice coil centering jig 1. It is set to a magnetic circuit, and a voice coil bobbin 4 having a voice coil 2 is jointed to a flat diaphragm 5 through a drive coupling cone 3 by means of an adhesive after the centering is executed. Then a jig 7 is inserted through a through hole 6a of a yoke 6, and the position of the jig 1 is shifted and pushed up near to a hole 3a of the coupling cone 3. An adhesive 9 is applied to the outside of a speaker main body through the hole 3a with use of a jig 8 so as to adhere the jig 1 to the speaker main body. Finally the jig 1 is adhered and fixed on the upper and inner periphery of the voice coil bobbin 4 to be some part of a vibrating system.

(Problems to be Solved by the Invention) In this way, in the past, the plane diaphragm 5 was connected to the voice coil bobbin 4 having the voice coil 2 via the coupling cone 3.
Since the voice coil centering jig 1 is removed before the voice coils are pasted together, the centering of the voice coil 2 becomes unstable, resulting in a drawback that quality may vary.

In addition, A in the figure is a heavy object installed on the back of the flat diaphragm 5. If the speaker is a woofer or the like, the heavy object A is added to the flat diaphragm 5 during the manufacturing process to suppress resonance. .

(Means for Solving the Problems) The present invention has been proposed in view of the above points, and its object is to provide a voice coil centering jig without removing the voice coil centering jig in the speaker assembly process. By incorporating the flat diaphragm while centering it, and then fixing the jig inside the speaker body, we were able to mount the voice coil with high precision, and this also allowed us to create a suitable mass for the vibration system. It is an object of the present invention to provide a method for manufacturing a flat diaphragm speaker, which suppresses resonance of the flat diaphragm and improves the performance of the speaker by adding the above.

As shown in FIG. It goes without saying that the through hole 6a is formed to push up the magnetic circuit, and includes any form of the through hole 6a as long as it does not adversely affect the magnetic circuit. After connecting the flat diaphragm 5, the jig 7 is inserted through the through hole 6a, and the voice coil centering jig 1 is inserted.
Shift the position of the voice coil centering jig 1 and push it up near the hole 3a of the coupling cone 3, and apply adhesive 9 from a suitable jig 8 through the hole 3a to the outside part of the voice coil centering jig 1 to adhere it inside the speaker body. Apply to.

In this case, the weight of the voice coil centering jig 1 becomes heavy (although, in general, in flat diaphragm speakers, the resonance of the flat diaphragm 5 is sharp in most cases, and as a countermeasure, especially speakers such as woofers) As shown in the previous example, the method of adding a heavy object A to the vibration system has been adopted, but in the present invention, since the voice coil centering jig 1 is attached to the vibration system, a separate It is possible to suppress resonance and obtain good sound quality without using the heavy object A manufactured by the above method.
