DETAILED DESCRIPTION OF THE INVENTION 1) In the present invention, the opening area of the
hole for adjusting the amount of 廿 □ Ill provided on the upper surface of the speaker box is N1
rotatably mounted on the upper surface. 1 expense Shiunoku J [more volume AII! In order to
prevent the movement of the par's setting position from moving from k, such as shocks, the
purpose is to set the position of the par after moving. is there. In the drawings, reference numeral
1 denotes a speaker box, and an upper surface of the speaker box 1 is provided with an Lγshaped clamp 3 for a volume of mW6 and is provided in the interior IBl. (The sound generator 12
is in the retina. 4 Poke 7. ・ Keep the second knee on the top surface 2 of the speaker box 1 2.
The lever 1 is rotatably provided on the shaft 11, and a grip rod is provided on the other end of
the bar 4 so as to protrude, and the lever 114 is provided with an elongated hole S which is
parallel to the axial direction. The long holes SK are opposed to each other, and the long holes 5
are fitted with a plurality of rod-like springs S capable of being mounted. The lever 4 is made of
plastic when it is opened, and a rod spring 4% IF + downwards the length 1. The vicinity of the
free end is fixed to s, and when external force is removed, it is restored by self-setting force. The
lever 113 rotates the lever 113 with the clamp a and the lever 4 is adjusted by the lever 4 so that
the size of the weighing can be adjusted.・ It is Reference numeral i denotes a housing, which is
supported by the middle stage 4B-74033-031 carrier 14 of the housing and a lid is installed in
the housing 1. At this time, the knob 4 of the lever 4 protrudes upward through the long hole 1
provided in the supervisor, and any one valley of the beast type tee 3 provided on the back of the
open side 4 of the eta rover 4 Because the free end vicinity of the rod-shaped spring is engaged.

increase the opening interview of the seventy three of the speaker box 1 Because the forest
spring is engaged with the valley of one of the monks of the cave 11, the lever 4 is turned by
191) y) And the rod-like spring ((1 $ P3) is pressed against the hole 1ir 5ir joint Lj, and once
again return to the valley of the ring.

+*:+シh? <) Tq LI i Adder 48-7403 3-04 When rotating the forceps S to move or turn the
breath 4-4, the rod-like spring-engages with each of the beast-like provocations 11 and -1 order
engagement Therefore, the lever 4 can be quickly and reliably installed at the correct position 4f,
and the volume control function is very easy, and the lever -4 set at the fixed position is shocked
or the like. It is effective to be able to always obtain the required volume without moving and to
have the effect as described above. Furthermore, it is easy to assemble and inexpensive to
squeeze the structure.・ Has a fruit.
