DESCRIPTION JPS56163383
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of
the present invention. 1 ... cylindrical body, 2.3.5 ... ... rib, 4 ... ... speaker mounting boss.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The present invention relates to a
spacer for mounting a car speaker which is not deformed. When adding a speaker unit such as a
car stereo to a car, although a spacer is used, effective consideration is not given to non-planar
non-planarized surfaces of blood, so this is not an influence of the mounting surface? Receiving
spacer is easy to deform. For this reason, the speaker unit itself also increases the influence V, so
that a uniform piston movement of the cone is hindered at the time of the speaker operation, so
that the performance of the speaker can not be exhibited. 1−/2?? 31 The present invention
was made to eliminate the above-mentioned drawbacks, and provides a spacer for car speaker
mounting having a shape that can hold sufficient mechanical strength Nu. The embodiment of
the present invention will be explained with reference to the internal blood of 9F. Fig. 2 (2) is a
cylindrical spacer body made of resin, etc .; on the inner wall surface of this cylindrical main
body l there are framelike ribs 2 and ringlike ribs 3 for preventing hineness, and speaker
expansion Is provided with a boss 4. The loudspeaker is added to the boss 4, especially the
speaker unit θ) It is thick and firmly installed so that it can withstand even heavy items. On the
outer wall surface of the cylindrical main body 1, ribs 5 for preventing lodging are provided. The
shape of the rib 5 is set so that the wavy protruding pieces 11 are aligned as shown in FIG.
According to the spacer having the above structure, even if there is deformation of the car's l, the
spacer itself is prevented from deforming due to the synergistic effect of the presence of the rib
2.3.5. Also in the future the speaker unit is weight or dog kicks in order to cope with high power,
but even in this case deformation is prevented because it is firmly supported by the existence of
the boss 4 above. Also, the existence of the ribs 5 makes it possible to prevent the sink marks
which are subject to appearance as well as appearance. Since the deformation of the spacer itself
is prevented in this way, it can not affect the speaker unit and it can make it fully demonstrate

the performance of the speaker. Also, in the future, the height dimension of the spacer will be
large (though it can be considered, even in that case, it is possible to obtain sufficient spacer
strength). Furthermore, it is possible to reverse the free dust of the thesain, the present invention
is not limited to the spacer for speaker sand attachment but it can be applied to spacers of
various products such as home appliances that require strength 2,
