DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mechanism for
preventing chattering of box type audio equipment incorporating a speaker such as a transceiver
and a radio. FIG. 1 shows a conventional mechanism for preventing clattering of a sound device,
in which a box-shaped chassis 17C projection 2 is completely formed, and a cover 3 covering the
box-shaped chassis 1 is a portion in contact with the projection 2 Adhesive to The adhesive tape
4 was used to prevent the transmission of the vibration of the box-shaped chassis and the
speaker (not shown) transmitted through the box IK to the cover 3. However, in this structure,
the projections in the box shape, 1, 2 '! -ELa6xo <nff "19 ░ I & 'B !,!: L, 1'1 ?" ?-Further, since
the pressure-sensitive adhesive tape 4 was thin, it was not possible to sufficiently suppress the
clinging. The object of the present invention is to ameliorate the above-mentioned drawbacks of
the prior art and to provide a simple and reliable mechanism for preventing the clutter of
acoustic equipment. The gist of this invention is that a projection of a cushioning material is
provided at the portion where the speaker mounting structure and the other structure are in
contact with each other. The present invention will be described below with reference to the
embodiments shown in FIGS. In FIG. 2, reference numeral 6 denotes a rubber seat provided at the
contact portion with the cover 3 in the box-shaped chassis 1. 3 is a front view, FIG. 4 is a crosssectional view taken along the line rz-a in FIG. 3, FIG. 3 solid line shows before assembly, and a
two-dot chain line shows after assembly. In this case, the rubber seat 6 is attached approximately

to the center of the contact portion of the chassis 1 with the covers 3 and 7 to prevent the
chassis and the covers 3 and 7 from coming into contact over the entire surface, and the
vibration cover 3 transmitted from the speaker 5 Prevent transmission to 7 FIG. 5 shows another
embodiment, in which a go 1,...) Seat 6 is fitted in a chassis. As described above, according to the
present invention, although two types of measures have to be taken, namely, forming a
protrusion on a seal and sticking an adhesive tape to a cover, as conventional measures against
cling. It suffices to provide only one kind of projection of the cushioning material, and has an
effect of being simple in structure and being capable of surely preventing the clinging. The
cushioning material may be made of rubber only, and any material may be used if it absorbs
vibrations such as sponge and vinyl chloride.
