Detailed Description of the Invention Unexplained Issues such as Speaker Equipment V Hose
Acoustic Banonol Suppresses Temporary Machine Vibrations to Get a Good Recycled Loaf Fall
into the Speaker Box. Speaker device 1 When this sound signal is imprinted, sound waves are t /
Jut from the back of the speaker in addition to the sound waves radiated to the eyes 11 and
absorbed by the sound absorbing material 8 temple which is arranged on the inner wall of the
speaker box The acoustic waves that are not absorbed will be reflected by the inner wall, and the
stationary fly is raised at the frequency that is satisfied by the same method of the box. If it
matches with the frequency of purple generation and the resonance frequency of the board
board, the rth level of J, yy / if / 12 hood becomes very large, causing a resonance phenomenon ·
0 or a box When the reflected waves in the interior are in phase with one another and canceled
out, the vibration level of the board decreases to non-beach. This kind of reckless four-legged
board [not limited to all boards (side board 1.1 ', top board 2. - F face board 2 °, back side board

A sound in such a frequency range radiates from the front of the speaker 6.7, and it radiates
from the front 1 fiO 1 and the legs are excited in the speaker box, the coil spring 91 compresses

31, it is a reinforcing role against the shooting of both boards and I'C? t None, 4 As shown by the
solid line in Fig. 5, the vibration novel of the board is suppressed, and the sound pressure
frequency of the speaker device is customized, as indicated by the solid line in Fig. 6, no heater /
dip occurs and the flat Bespoke Quantity 6Q In addition, it is possible to further suppress the
vibration level of the board by further adjusting the compressive force or tension of the coil
spring 9 so as to displace the low frequency circumference of the board with his frequency τ. If
the vibration level of the boat is adjusted so that the vibration level of the boat is C uniformly for
each frequency f, and its level is set to A so that the level changes excessively, It feels like a
spitless sound that does not include it. This current urine, the loudspeaker device V'c productive

coil of the same word element of the dividing funny notch so that it comes to the node 6 vc of the
material. Coil spring 9 is 仝 1, and even if it is still fine as it is, vibration of the board itself is
suppressed (i-type is suppressed, the sound pressure frequency characteristic is flattened and
reproduced sound is made good quality sound, but vibration prevention of the coil spring 9 itself

Fig. 4, for example vibrator rubber t rubber 5 il spring 9 and the young boy ___ ___ ___ 0
