DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a voice coil
attachment device for a flat plate speaker using a reinforcing ring tube for further perfecting the
connection between the diaphragm and voice coil of the flat plate speaker. Conventionally, a
voice coil mounting device as shown in FIGS. 1 and 11g2, and the voice coil 2 of the IIII figure is
bonded to the back face of the diaphragm 1 with an adhesive at the position of the joint 1R13
with the diaphragm l. The voice coil 2 shown in FIG. 2 is bonded in such a state that the
diaphragm IK is fitted to the portion of the large recessed groove 4. Both are bonding of the
diaphragm 1 and the voice coil 2 most frequently performed. However, the bonding area at the
junction 3 between the diaphragm 1 and the voice coil 2 at the 11% and 0% in the prior art is
very ho, so that the voice coil 2 is lost at 1 o'clock. There is a piety. Further, in the case of the
prior art of FIG. 2, when the diaphragm 1 is made into a honeycomb structure in order to
improve the speaker characteristics, there is a drawback that the processing of the concave
groove (the processing of the groove causes high yield of pregnancy @ 1 at mass production).
The present invention is to improve the aforementioned missing JaYr. FIG. 3 is a structural view
showing an embodiment of the present invention. In FIG. 3, the voice coil zFim is engaged with
the strong ring 5 and bonded to the back surface of the first diaphragm 1 in the combined state.
The necrotic parts to be attached are the junction 3 of the voice coil 2 and the jIl end 6 of the
reinforcing ring 5 and the other circumference fi? The bonding 11-3 and the MI end 7 are
bonded to the diaphragm 1, and the one circumferential end 6 and the voice coil 2 are bonded. Is
it a so-called voice coil attachment device accident? The flat loudspeakers are large in multi-point
motion, and at least the large voice coil 2 and the voice coil mounting device are mentioned

above. (2) The bonding between the diaphragm 1 and the voice coil 2 is doubled by the adhesion
of the reinforcing phosphor f5f) jI 111117 compared to the conventional one in FIG. Further, the
fitting of the voice coil 2 and the reinforcing ring 5 further reinforces the voice coil 2Yr. Next, in
the conventional case of FIG. 2 and in a single piece, there is no need to process the diaphragm 1
of the present invention company No. 2 cam willow body, so that the yield of the diaphragm 1
can be lowered and a mass-produced flat plate. As described above, according to the present
invention, the connection between the fi # im movable part and the voice coil is completed by the
present invention, and the present invention can be applied to the diaphragm of the new one
structure, and the yield is low. The addition of a reinforcing ring tube has the advantage of
increasing the trend of the voice coil.
