DESCRIPTION JPS52147023
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view of a conventional speaker, and
FIG. 2 is a perspective view of an essential part of the inventive speaker. 21 is a speaker frame,
24 is a mounting hole. 21b is the outermost circumferential rising edge, 21a is a protrusion, and
22a is a notch-22 is an arrow.
DETAILED DESCRIPTION OF THE INVENTION One aspect of the present invention relates to a
slider which facilitates the mounting of an arrowhead which is placed and affixed to the outer
periphery of a speaker frame. The structure of the conventional speaker is L as shown in FIG. 1,
and in order to attach the arrow 2 to the outer periphery of the frame 1, the outer edge of the
arrow 2 is provided on the outermost periphery of the frame 1 It was placed in contact with the
plate and placed in place, and it was affixed -C, but it is not positioned in the circumferential
direction, so it has nothing to do with the eye of the operator, requiring skill in the work and easy
to move Shifting in the circumferential direction /% /// jI ++ C)> 2 causes a defective product
such as blocking the mounting hole 4. In order to solve the problem, a speaker having a structure
in which an upright piece is provided in the periphery of the weighted hole to restrict movement
in the circumferential direction has been considered. However, in such a structure for locking
both arrows 4), a precision of G and several digits is required between the positioner of the
upright piece and the shape and size of the arrows, and the arrows Parts management is
extremely around 3 because frames of different positions and dimensions of standing pieces
must be prepared. であった。 This invention solves the disadvantages of the prior art by making
it possible to lock the central part of the arrow and paper. The embodiment of FIG. 2 will be
described in detail. In d, 21 is a frame, and the outer peripheral portion of the core 23 is attached
to the outer peripheral portion thereof. 211I; -arrangement distance of mounting hole 24 OrA
center position 7 lly-arm 21 is a projecting portion in which the outermost facing edge 21b is
protruded inwards The cut arrow 223a formed in the substantially central portion is locked.
Therefore, in the case of sticking the arrow 22, the notch 22 m is disposed so as to be engaged

with the protrusion 421 m while adhering while fixing the outer edge of the arrow 22 while
holding the outer edge of the arrow 22. The circumferential movement can be completely
restricted. As described above, according to the present invention, the notch is provided at the
outermost periphery of the frame and the notch provided at the center outer edge of the arrow is
engaged with the projecting portion, and is locked at the center of the arrow. Therefore, the
assembling work 7 requires no skill level, the working efficiency is remarkably the same, and it
does not require a strict method accuracy between the arrow and the frame as compared with
the prior art. Therefore, it is easy to form valley parts. Even if it is an arrowhead in the shape of a
stationery, the same frame can be used by locking the central part of the groove D, so there is no
need to form a room according to the arrowhead, and the same frame is used Can have an
excellent effect on mass production, such as facilitating parts management.
