DESCRIPTION JPS54113538
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of a loudspeaker
according to the present invention, FIG. 1 is a sectional view, and FIG. 2 is a plan view of a
reinforcing ring. 1 ...... corn, 2 ...... voice coil bobbin, 3 ...... voice coil, 4 ...... damper, 5 ......
reinforcing ring, 5a · .... Perforation.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The present invention is directed to
a speaker in which the ld voice coil bobbin and the cone neck portion are strengthened. The
conventional speaker 7 has a weak point on the neck portion of the oval coil bobbin or cone, so
that there is a disadvantage in that the bobbin bends or the radial division of the cone occurs.
The present invention solves the above-mentioned drawbacks 17, but it is possible not only to
expand the piston zone, but also to provide a speaker which can be adjusted in mass / well /-1pin 5G-/- 3 :! fある。 Hereinafter, an embodiment of the present invention will be described
based on the drawings, m. FIG. 1 is a cross-sectional view, and FIG. 2 is a plan view of a single
ring. In the figure, 1 is a cone, 2: a voice coil hobin 3. d Hois coil, 4'r: r9 'member is shown. Neck
of the cone 1)? la ,! : A voice coil hobin 2 is provided with a filler / gug 5 to make a voice coil
pobi / 2 and a neck stand of a cone 1 hatched with a 1j. Reinforcing ring 50 柑風 (- beetle,
Epilachna 1 small WAS, also old in Yukazari link 51 1 mood arch ladle, for example, 1. It is
possible to eliminate the interference of the reproduced sound by n by providing a fistula hole 5a
by puncturing the iC hole. According to the speaker 1 of the present invention, since the
reinforcement link is not inserted between the Konononok part and the 7's film bobbin, the neck
portion of the cone and the hovin or the like of the bobbin as conventionally seen (F In addition,
since the neck 13 of the core / co is also predicted, it is possible that the radial damage 11 will
occur; Also, it can expand the piston zone of the cone, and it has a cloudy effect by adjusting the
mass 2-1 balun.
