[Detailed Description of the Invention] In the case of a non-inventive device such as a speaker
device or the like, an acoustic banonor suppressing a temporary mechanical vibration to obtain a
good reproduction rod and dropping it onto a speaker box. Loudspeaker device 1 When the voice
signal is squeezed, sound wave t / Jut from the back of the speaker besides sound wave radiated
to eye 11 force and absorbed by sound absorbing material 8 temple placed on the inner wall of
the speaker box The sound wave which does not absorb and absorb is reflected on the inner wall
and goes up standing at a frequency that is sufficient with the same method of the box. When
this frequency is matched with the resonant frequency of the box board and the resonant
frequency of the box board, the j, yy / if / 12 hod = rth level becomes so large that a resonance
phenomenon occurs. The board's vibration level will be unbelievably low if the reflection wave
inside is going to go out with him. This good-looking four-legged board [all boards (side board
1.1 ', top board 2. not limited]. −F side board 2 °, back side board 3. The same phenomenon
occurs with the front board 3 ′ ′) vc, and the general phenomena are mixed up with the vague
VC, and the speed of vibration of the back board 3 is about 100 t (z as shown by the dotted line
in FIG. 5). It becomes a special order shown by the thick beri and γ innop, and the sound
pressure is divided into four as shown by a line on the first row J. Fig.6. Correspondingly, a bead
or dip is generated -C. Such a special order with a large peak and dip causes ashes of the
reproduced sound to occur, and it is heard that it remains like "fi'i Run Brno" and this, 1'LF is 1 !!!

reproduction noise is blocked as a strange sound 0 wood note to prevent the generation of the
generated anomalous abnormal sound vC 44 た た J) 屯 屯 導 生 生 生 生 生 生 生 Vc Vc Vc Vc Vc

The sound of such a frequency range radiates from the front of the speaker 6.7, radiates from the
front of the speaker 6.7, and the foot is inspiring in the speaker box, but the coil spring 91 has a
compression force or tension = no J0 Is it a suspension between the back boat 3 and the r + iTim
boat 31 and take it out? Without t, as shown by the solid line in FIG. 5, vibrational vibration of
the board is suppressed until the sound pressure frequency of the speaker device is customdesigned, as shown by the solid line in FIG. Custom-designed 6Q Furthermore, by adjusting the
compression force or tension of the coil spring 9 by adjusting the compression force or tension
of the coil spring 9, the vibration level of the board can be suppressed. J) If V's vibration level of
the boat is four times C uniform with frequency f reduced, and if the level is adjusted so that the
magnitude of excessive change A, the reproduced sound will be an unusual noise It feels like a
spit noise not included. This present urine, · · · speaker device V 'c 喫 こ 、 、, I ′ L べ ′. Also,
the coil spring 9 has a function as a choke coil of the same word element of the dividing nontank, so it becomes a node 6 vc of the material. Even if the coil spring 9 is 、 1, the quality of the
board's vibration (I-squeezing suppressed as it is), the sound pressure frequency characteristic is
made flat and the reproduction sound has a good sound quality, but the vibration control of the
coil spring 9 itself is As shown in Fig. 4 (as shown in Figure 4), if you are in the inside of a good
material for vibration isolation and custom-made materials, for example, the inside of vibration
isolation rubber material t co 5 ile spring 9, its jumbo vC size, and so on.
