DETAILED DESCRIPTION OF THE PRIOR ART The present invention relates to a plate structure
for fixing a speaker to a mounting plate such as a rear tray or a baffle of an automobile.
Conventionally, in order to fix the speaker to the baffle directly, 1 to fix the speaker to the iron
plate such as the rear tray of the automobile, etc. were fixed with screws via the reinforcement
fittings respectively, so that screws and reinforcing brackets were necessary There was a
disadvantage that the cost became high and one handling required a lot of time. Therefore, the
present invention proposes a fixing tongue piece protruding from the frame of the speaker body
toward the lower part of the outer peripheral edge of the frame (1), and the fixing tongue piece
and the outer peripheral edge and the opening to the speaker mounting plate from K The inner
peripheral edge of the opening edge is sandwiched so that the insertion groove into which the
fixing tongue piece can freely enter and leave is provided on the inner peripheral edge of the
attachment plate so that the speaker body can be separately attached to the attachment plate
Provide a speaker mounting structure that can be fixed easily and quickly without using parts.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention
will be described with reference to embodiments shown in the accompanying drawings. FIG. 1 is
a perspective view showing a state before assembly of a speaker mounting structure according to
the present invention, and FIG. 2 is a sectional view showing essential parts after the assembly In
the figure, reference numeral 1 denotes a speaker body, 2 denotes a frame of the speaker body 1,
3 denotes an outer peripheral edge of the nuclear frame 2, an edge 5 of the diaphragm 4 was
provided on the upper surface of the outer peripheral edge 3, a backing 6 And a gasket 5 '. 7 is a

magnetic circuit of the speaker body 1, and 8 is a terminal. Reference numeral 9 denotes a fixing
tongue piece which protrudes from the arm portion of the frame 2 toward the lower portion of
the outer peripheral edge 3 and the distance between the fixing tongue piece 9 and the back
surface of the outer peripheral edge 3 is the distance It is desirable to form it slightly narrower
than the thickness Dl of the inner peripheral edge portion 12 of the opening portion 11 opened
in the attachment plate 10 and apply resilient force between the fixing tongue piece 9 and the
outer peripheral edge 3. Although the illustrated fixing tongue piece 9 is formed by cutting and
raising the arm portion and the outer peripheral edge 3 of the frame 2, it may be separately fixed
to the frame 2. The opening 11 opened in the mounting plate 10 is formed on the inner
peripheral edge 12 to such an extent that the outer peripheral edge 3 of the speaker body 1 rests
and the fixing tongue piece 9 provided on the frame 2 is formed on the inner peripheral edge 12
Inserting freely inserting groove 13 is formed so as to be connected to the opening 11.
Therefore, K for fixing the speaker body 1 to the opening 11 of the mounting plate 10 is formed
by fixing the fixing tongue piece 9 provided on the frame 2 to the mounting plate 10, the speaker
body 1 is attached to the opening 10 from the side of the magnetic enclosure 7 so that the fixing
tongue piece 9 enters the insertion groove 13, the fixing tongue piece 9 is inserted into the
insertion groove 13 Slightly protruding from the back surface of the main body.
Next, when the speaker body 1 is pushed against the attachment plate 10 in the desired
direction, the fixed (3) tongue piece 9 moves from the insertion groove 13 to the back surface of
the inner peripheral edge 12, so that the speaker body 1 is fixed The tongue piece 9 and the
outer peripheral edge 3 are fixed to the mounting plate 10 by sandwiching the inner peripheral
edge 12 of the opening portion 11. It is to be noted that the fixing tongue piece 9 provided on
the outer peripheral edge and the fixing tongue piece 9 It is a matter of course that K may be
provided so as to arrange one or a plurality of insertion grooves 13. As described above, the
fixing tongue piece 9 projects from the frame 2 of the speaker body 1 toward the lower part of
the outer peripheral edge 3 of the frame 2, and the fixing tongue piece 9, the outer peripheral
edge 3 and the K Since the inner peripheral edge 12 of the opening 11 opened in the speaker
mounting plate 10 is sandwiched and the insertion groove 13 into which the fixing tongue piece
9 can freely enter and exit is provided in the inner peripheral edge 12 of the mounting plate 10,
When the fixing tongue piece 9 is fitted to the insertion groove 13 and the speaker body 1 is
mounted in the opening portion 11 and rotated in a desired direction, when the fixing tongue
piece 9 and the outer peripheral edge 3 sandwich the inner peripheral edge 12, K Therefore, it is
possible to fix the speaker body 1 to the mounting plate 10 simply and quickly, and it is possible
to reduce the cost by that it does not require any parts for attaching the speaker body 1, such as
screws.
