DETAILED DESCRIPTION OF THE INVENTION In the present invention, a backing attached to the
outer periphery of the speaker frame which is sanded during manufacture and assembly of the
speaker is used for attaching a mistake in attaching the speaker mounting hole provided on the
outer periphery of the frame. The purpose is to prevent blocking due to slippage after wearing.
When attaching the backing to the outside of the speaker frame with an adhesive or the like at
the time of conventional speaker assembly, the worker installs the speaker on the outside w 4s of
the frame. Because it was stuck while avoiding this, the operator could use extra nerves, or the
backing would be squeezed and dried before sticking and the speaker mounting hole There were
drawbacks such as blocking. Prior art, such defects have been eliminated, and will be described
below with reference to the embodiment shown in the drawings. FIG. 1 is a front view of a
speaker assembled by applying the present invention, FIG. 2 is a side sectional view of a part
thereof, and FIG. 3 is a perspective view of the main part thereof. The cone type speaker is to
stick the outside edge of the cone 1 with the backing 3 in the form of 2KN% for external use of
the speaker frame 2 through the adhesive F15 ffl via the adhesive agent. 2 has a plurality of (four
as shown in the drawing) speaker mounting holes 4 for attaching the speaker to the board Kjlj of
the cabinet, so when attaching the backing 3 (2) It is necessary to avoid the mounting hole 4 and
install it. In the present invention, the speaker mounting hole 4 is surely avoided so that the
backing 3 can be adhered and fixed to the outer peripheral portion 2 of the speaker frame 2 with

an adhesive. When the mounting hole 4 is stamped and formed, the projecting piece 5 is formed
around the speaker mounting hole 40 or a part thereof. In addition, this protrusion W5 is formed
in said backing 30 sticking gauze. By providing the projecting piece 5 in the speaker mounting
hole 4 as described above, when sticking the backing 3 described above, the worker confirms the
position of the speaker mounting hole 4 with eyes by the presence of the projecting piece 5 It is
possible to easily position the backing 3 without sticking, and it is possible to completely
eliminate the possibility of causing an operation error, or the backing 3 is not completely dried
after the adhesion of the backing 3 and the like. Even if there is a possibility of a displacement,
the projection (3) serves as a stopper and the displacement does not occur.
Furthermore, since the projecting piece 5 can be simultaneously formed at the time of punching
and forming the speaker mounting hole 40, an extra manufacturing process for forming the
projecting piece 5 is not required. In the figure, 6 is a dust cap, 7 is a voice coil, 8 is a damper, 9
is a top plate, 10 is a ferrite magnet, and 11 is a yoke. In the present invention, as described
above, at the time of punching and forming the speaker mounting hole provided on the outer
peripheral portion of the speaker frame, a projecting piece is attached to the riverside of the
speaker mounting hole or a part thereof, When attaching the backing to the outer portion of the
speaker frame by providing a speaker formed on the attaching side of the backing to be used, the
worker confirms the speaker attachment hole 1 as described above. There is no need to use extra
nerves to stick to avoid this, and the backing may not come off as a speaker mounting hole tube
(due to work (4) mistakes or backing offset after sticking) In addition, since the projecting piece
can be formed simultaneously with the punching of the speaker application hole, there is an
advantage that no extra process is required.
