DETAILED DESCRIPTION OF THE INVENTION A speaker system according to the present
invention 1 wherein one protector is used to prevent the generation of interference distortion
sound due to damping of the protector, damping of the baffle plate and photographing of the
loudspeaker O. About. Conventionally, a speaker system configured as shown in FIG. 1 is widely
known in order to prevent the protector from being crimped and to prevent the occurrence of
distortion noise and the like due to the movement of the speaker. It is provided with four prongs
(1) 73 on the four peripheral edges on the panful plate 2 side of the cabinet 1 and a projecting
edge 3 for lid attachment, and a speaker 6 is attached around the through hole 4 of the baffle
plate 2 by a screw 5 ing. A rubber ring 9 or the like is stuffed into the bent locking piece 8 of the
pusher 11 fitted into the projecting edge 3 and the inside of the projecting edge 3 is stably held
(the baffle plate 2 and the protector are held. The generation of chattering noise between them is
prevented. Furthermore, a buffer member 11 is interposed between the frame edge 1 ░ of the
speaker 6 and the baffle plate 2 supporting the frame edge to prevent generation of interference
distortion sound and the like by the speaker 6. However, in such a Spycan stem, the
configuration of the dam which prevents the above-mentioned flicking stop and interference
distortion sound becomes complicated, and the work of attaching the speaker 6 and the
protector 7 using different shapes and shapes of the large pancake / gug is complicated. And
there was a drawback that the workability was extremely bad. The present invention is intended
to ameliorate such conventional structural problems in operation 1 and, in particular, by using a
single damping material, protection of the protector (2) locking and interference distortion noise
can be prevented. It is an object of the present invention to provide a novel speaker / stem
capable of easily achieving not only the damping and stable holding of the baffle plate.
Hereinafter, an embodiment of a speaker / stem according to the present invention will be
described with reference to the drawings. FIG. 2 shows an embodiment of the present invention,
and is a plan view showing the main part in a cutaway manner, in which 12 is a cabinet and 13 is
a baffle plate. At four peripheral edges of the cabinet 1 on the side of the baffle plate 13, step-like
notches 14 and 15 to which a later-described Sanon u frame and a protector are attached are
formed. Further, the baffle plate 13 is provided with a sound emission hole 16 of the speaker,
and a continuous braking plate 17 is attached to the front face of almost all the baffle plates 13
except the sound emission hole 16 and the side surface of the notch 14. It is laid by the method
such as wearing. A speaker attached to the 181?j baffle plate 13 with a buffer material such as
felt or malt bran cut out to a suitable size as the damping plate 17, the frame edge 20 by the
screw (3) 19. Is fixed to the buckle plate 13 via the brake plate 17.
Reference numeral 21 denotes a sanon u frame supporting the four circumferences of the
protector 22, which are fixed by screwing or other methods. These fixed and integrated parts are
coupled to the cabinet 12 by the locking piece 23 of the protector 22 being fitted to the notch 14
through the braking plate 17. In this case, the sash frame 21 is engaged with the notch 16. If
necessary, the series of brake plates can be extended between them to prevent unnecessary
vibration between them. According to such a configuration, the braking plate 17 cushions
(supports) the protector 22 with respect to the cabinet 12, and therefore, generation of a billet
due to unnecessary vibration generated between the protector 22 and the cavity end 12 is
prevented. Can be prevented. Further, the damping plate 17 is also interposed between the
speaker 18 and the baffle plate 13 for supporting the same, and effects of generation of
interference distortion sound on diffraction or reflection of sound waves generated in this
portion or on air conditioning resonance (4) are effective. Can be prevented, and the acoustic
characteristics can be improved. Furthermore, since the braking plate 17 is laid over
substantially the entire surface of the baffle plate 13, the damping effect of the plate vibration of
the baffle plate 13 can be obtained. As described above, according to the present invention, the
front surface of the baffle plate is covered with the damping material, and a portion of the baffle
material is interposed between the speaker and the baffle plate to which it is attached. The
speaker protector is resiliently held at this side portion, thereby cutting out a single braking plate
and bending it to lay it on the baffle plate, thereby making the cabinet and the protector At the
same time, it is possible to prevent the generation of a rattling noise generated between them
and the braking of the baffle plate, and the prevention of the generation of the interference
distortion noise generated between the speaker and the baffle plate. In addition, since one of the
constructions and structures for that purpose is extremely simple, it is excellent in practicality.
