【Detailed Description of the Invention】 Speaker net attachment rlLK to prevent dust and dust
from entering the present speaker Speaker layout for easy installation of superior installation
with little slackness with simple construction It is intended to be aimed at · Bush In general
speaker nets are glued with adhesive etc. Panel Kjili! It is long ago. However, there was a
disadvantage that sagging was easy to sell in the central part of the pigeon speaker net, - and 7)
"2 '· As a result, the scattering work of the speaker was extremely inefficient K. The present
invention is to eliminate the above-described conventional drawbacks and to provide an excellent
speaker net attachment device with a simple configuration and less slack. Hereinafter, with
regard to the speaker net attachment device of the present invention, as well as one aspect of the
embodiment, Kl! Make it clear. In the figure, reference numeral 1 denotes a panel, 2 denotes a
speaker net mounting surface formed on the front surface of the panel 1, and 8 speaker grills
mounted on the speaker net mounting side. Separate 4 is a speaker net where the outer
circumference is deposited on the speaker net mounting surface, Panel IK% wearing a sound
release hole is put on the loudspeaker 8 It prevents dust from entering the dust O is there. 6 is a
circumferential recessed portion formed in the speaker net scattering surface 2], 6 is formed in
the speaker grill 3 and enters the concave portion 6 when the speaker grill # 3 is attached to the
speaker net scattering surface 2 Kjlll] It is a convex portion to be inserted. 7 Extended speaker
grill 8 is a thrusting portion formed on the part corresponding to the speaker grinding
attachment surface 2 of the speaker grill i (-7-3) on the glee which adheres to the speaker net
attachment surface 2 with supersonic sound. In the case of assigning the speaker grill 3 and the
speaker net 4 in connection with the upper distribution example, first place the sparkanet 4 on

the Svikane 7 "Diffusion Wi 2 and as shown in the 891 m 'C / I K Weigh the speaker grill 8 from
above. Then, a force in the direction of the arrow A is applied to the speaker grill 3 to
ultrasonically adhere to the speaker net mounting surface. By this fact K is formed in the speaker
grill 3 and the knocking portion 7 is melted, the speaker net mounting surface 2, the speaker
grille 3 and the speaker net 4 are welded at the same time, and the convex S formed on the
speaker grill 3 is welded to the speaker net mounting surface The ninth speaker net 4 entering
the formed concave portion 6 is attached with its outer peripheral portion being pressed and
tensioned uniformly without looseness. In order to ultrasonically adhere in ceramics, real Jeifi,
the center part T is formed to be out of the convex part and the part 7 comes in contact with the
outermost periphery of the speaker net 4 at the end of the supersonic # IL clothing arrival So
that the height is slightly higher than the convex portion 6.
) 4 As apparent from the above embodiment, the present invention is constructed such that a
concave portion is formed on the speaker net mounting surface, and when the speaker grill is
deposited, it is inserted into the concave portion and absorbs the looseness of the speaker net by
the concave portion Therefore, it is possible to easily attach speaker nets with less slackness.
