becomes easy, and the speaker unit is less likely to get wet even if water drops because there is
no speaker unit on the front, so the speaker unit By placing it on the back plate, it faces the
installation wall, and the sound emitted from the speaker unit can be reflected to the installation
wall to make the sound louder. In the experimental results showing the difference, the
installation wall material is P tile As a result of measurement from a position 1 meter away from
the installation wall, the direct sound measured from the back direction showed 70.2 dB, but
from the front direction with the leg projections in contact with the installation wall The
reverberation sound shows 72.2 dB, and as the difference between the two is 2.0 dB, it can be
understood from the fact that the installation wall can fully play a role as a reverberation plate.

structure in which the measuring instrument 31 is installed at a position away from the surface
of the installation wall 7 by an arbitrary distance L, and the length of the distance L is Although it
is not limited to 1 meter as an arbitrary numerical value, the installation wall 7 is illustrated
vertically but may be horizontal, and the echo sound measurement of this figure measures the
front plate 5 of the box 2 of the device 1 It is desirable to have a gap 9 between the back plate 6
of the box 2 and the installation wall 7, and it is preferable to set the adjustable area of the gap 9
to a gap width S. The change of the sound emitted from the sound generation unit 4 due to the
addition or subtraction of the gap width S is reflected on the installation wall 7 and the original
volume emitted from the sound generation unit 4 can be adjusted, but it is arbitrary constant.
The leg projection 8 is removed because it is necessary to measure also the state in which the
gap width S with the back plate 6 in contact with the installation wall 7 is 0. Except for are
shown.

FIG. 7 is a measurement result table in which the gap width is adjusted. The echo sound is
measured with the structure shown in FIG. 5, and the measured volume changes with the gap
width S, and the gap width S is too wide. Even if it is too narrow, the volume decreases and the
maximum value is that the gap width S is 4 mm, so the length of the leg projection 8 defining the
width of the gap 9 is best 4 mm.
[0022]
FIG. 8 is a measurement result table of the volume change due to the difference of the
installation wall material, the echo is a measurement from the front direction shown in FIG. 5,
and the direct sound is a measurement from the back direction shown in FIG. In the case of steel
and P tiles, which have high echo effects, echoes show larger values, and in the napping mat,
which is a sound-absorbing material, direct sound exhibits larger values than in low echo
materials. As long as the sound absorbing material is not used as the installation wall 7, the
installation wall 7 can enhance the echo effect.
[0023]
Although not shown, other measurement results will be described. The measurement direction of
the device 1 is reversed from that of FIG. 5 with respect to FIG. In the case of 66.6 dB, it shows a
lower value than echo and direct sound, so the device 1 itself is 1 meter away from the
installation wall 7 and the measurement distance L is 1 with no echo effect of the installation
wall 7 Measured in meters (2 meters from the installation wall 7), the measured value from the
front direction is 63.6 dB, and the measured value from the back direction which is direct sound
is 66.4 dB. there were.
