DESCRIPTION JPS5474519
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view showing one
embodiment of the speaker apparatus of the present invention, and FIG. 2 is a cross-sectional
view showing another embodiment of the present invention. 1 is a cabinet, 2a and 2b are
speakers, 3 is a front baffle, 4 is a rear baffle, 5a)! A steel plate, 5b is a damping material, 5c is a
bending portion, and 8 is a speaker grill.
DETAILED DESCRIPTION OF THE INVENTION In general, a speaker system has been proposed
that allows the speaker grille to be removed as needed. The present invention relates to a
speaker device capable of dismounting such a speaker grill, and in particular, a speaker grill can
be easily mounted, and the speaker grill can be mounted without particularly providing a device
for allocation. It is intended to be able to obtain the effect of An embodiment of the loudspeaker
system according to the invention will now be described with reference to FIG. FIG. 1 shows a
cross-sectional view of a speaker grill with a speaker panel in a good condition. In FIG. 1, fil
represents a cabinet of the speaker apparatus, and upper and lower and left and right walls of
the cabinets il + are constituted by relatively thick plates (1 m), and the speakers (2 m) and (2 b)
are removed. Composed of front baffle (3) and rear baffle (4), which are attached to As this
distribution plate, a steel plate such as an iron plate or an alzimmer lira gozan is used, and one
obtained by winding and laminating a damping material (5b) such as a rubber adhesive or the
like is used. A distributed slope-placed damping steel plate in which the steel 1 [(5 m) is
laminated with a damping material (5b) placed thereon has a large weight and can reduce the
resonance acuity of the plate vibration and reduce the deterioration of the sound quality very
much. In the present invention, a part of the steel plate (Sm) on the upper layer side and the
lower layer side of the front baffle (3) is key-folded forward, and this folded part (5e) K large (K)
(large) 5d), insert the rubber ring (7) into the hole (5d), and insert the bottle (8a) established
behind the speaker grille (8) into the rubber ring (7). Fix (8). Since the present invention is
configured as described above, insert the bin (8 m) embedded in the back of the spy (2) cargril

(8) into the hole (5 d) through the rubber ring (7) K) speaker Since the grille (8) can be fixed, the
speaker grille (8) can be removed from the item. Also, in this example, the front baffle (3) and the
rear baffle (4) all damping steel plates are used, and the weight of this baffle + 31 + 41 is
increased and the resonance acuity of plate vibration is decreased, so the sound quality is
deteriorated. Can be very small. Further, the speaker grille (8) is fixed to the front baffle (3) K,
and the front baffle (3) is made to be non-resonant, and is composed of nine damping plates.
Vibration is controlled and sound quality is improved.
As described above, according to the present invention, the speaker grille (8) can be easily
mounted in the cabinet tllK and the speaker grille (8) is attached to the front baffle (3) formed of
the split plate in particular. The effect of damping can be enhanced without providing a device
for allocation. (3) FIG. 2 shows an embodiment of the crucible of the present invention. In FIG. 2,
parts corresponding to FIG. 1 are given the same reference numerals, and the detailed
description thereof is omitted. In this example of FIG. 2, a part of the steel plate (5 m) on the
upper layer side and the lower layer side of the front baffle (3) is folded forward in a key-like
manner, and this fold on the upper and lower sides. The speaker grille (8) is fixed to the cabinet
(1) by sucking the portion (5C) with the bins (8a) provided on the upper and lower sides of the
back surface of the speaker grille (8) The other components are the same as in FIG. It can be
easily understood that the effect similar to that of il1 can be obtained also in FIG. In the above
embodiment, although two copper plates are used as the damping plate, it is of course possible to
use three or more layers. Of course, other damping plates can be used as the damping plate
without being described in the above example. Furthermore, the present invention is not limited
to the above-described embodiment, and various other configurations can be made without
departing from the scope of the present invention.
