BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of the main part
of the first embodiment, FIG. 2 is a cross-sectional view of the main part of FIG. 1, and FIG. 4 is a
partial perspective view showing a modification of the pressing member, FIG. 5 is a partial
perspective view showing another modification of the pressing member, and FIG. FIG. 7 is a
perspective view showing another usage example of the pressing member of FIG. 5, and FIG. 8
shows still another usage example of the pressing member of FIG. It is a perspective view. In the
drawings, 1 is a speaker box, 1a is a mounting hole, 2 is a speaker unit, 2a is a frame, 2b is a
rising edge, 3 is a pressing member, 3a is a fitting groove, and 3c is an opening.
DETAILED DESCRIPTION OF THE INVENTION This invention relates to a mounting device for a
speaker unit. Regardless of whether the speaker system is a phase-reversal type or not, the frame
in the speaker unit is in close contact with the front of the speaker box so that the air in the
speaker box does not leak from an unplanned position. Although it is known that the desired
high-quality sound can not be obtained-conventionally, several folded pieces are provided on the
front of the outer periphery of 7 frames of the speaker unit, and the folded pieces are used for
the speaker box. Since it is also in contact with the back of the front wall and screwed them in, it
is also equivalent to one half the thickness of the folded piece between the front of the frame of
the speaker unit and the front and back of the speaker box. Between the lyso and the l3 are
formed, and air leaks from this gap to deteriorate the sound quality. Therefore, in the past, in
order to improve the degree of sealing between the speaker unit and the speaker box without
taking a gap between the contacts, the seal material may be taken in between @, or is not it? The
front side of the frame of the speaker unit was bonded to the rear side I i [I wall of the speaker
box. If the mounting work of the speaker unit becomes troublesome, and the two-piece adhesion
is constant, there is a disadvantage that the speaker can not be replaced after it is Φ, and
furthermore, it can be fairly divided by mere flat contact. It is difficult to obtain the degree of
stickiness, and the cedar shape of the mounting member and the speaker frame to be used

suffers from various limitations in terms of design as well. This invention eliminates such
conventional drawbacks. Even though it has a very simple structure, it can be mounted in close
contact with the speaker unit t speaker box. Furthermore, this mounting can also improve the
mechanical strength of the speaker box, and high-surface treatment of originality It is an object
of the present invention to provide a mounting device for a speaker unit that can In the
following, the idea of the invention will be described in detail with reference to the embodiments
shown in the attached drawing. In FIG. 1, FIG. 2 and FIG. 3 showing one embodiment, it is a 1
speaker box, and a mounting hole 1 '' + 1 '' tl! With setting. Screw holes 1b are formed on the
outer side of the several mounting holes 1a and 1a, respectively, and Ib · knee 眞 5 ·-tl-are
formed. The 2Fi speaker unit has a front rising green 2b # Jt4 formed on the outer periphery of
the frame 2a, and the speaker unit 2 is fitted to the mounting hole 1a from the front and
protrudes on the front of the rising edge 2bk speaker box 1 I am doing it.
It is a diaphragm of 2C control speaker unit 2. 3 紘 A pressing member formed in an annular
shape that can polymerize in the forward direction of the frame 2a and the outer peripheral
portion of the mounting hole 1a, and is engaged with the rear surface ecd of the flashing member
3 and the rising edge 2b of the frame 2 & And a threaded hole lb formed at the outer corner of
the mounting hole 1a. The mounting holes 3b, 3b, ... overlapping with 1b, ... are N #, and the
pressing knees on the front surface of the speaker box 1 with the form of the plunging into the
rising green 2btfi joint groove 3a of the 7 frame 2a 3 固定 4 4, 4 會締付締付 (−6 (−6 −6 ス

the screw holes lb, lb ·· −. In the above embodiment, the fitting groove 3a2 is formed on the rear
surface of the ring-shaped pressing member 3. For example, as shown in FIG. 4, the pressing
member 3 is formed by punching a metal plate in a ring shape. Forming an opening 3 ° facing
the mounting hole 1a, burring this opening edge 3c to the rear and overlapping with the inner
circumferential surface of the rising edge 2b! 1M3d1r shape, by fixing the thin body 3θ
overlapping the outer peripheral surface of the rising edge 2b to the rear surface of the pressing
member 3 between the rising green 3d and the I-shaped body 3e Also, as shown in FIG. 5, the
pressing member 3 is formed of a plate-like member, and the fitting groove .0. Therefore, in the
embodiment shown in FIG. 6, the pressure member 3 larger than the speaker unit 2 is grooved as
shown in FIG. As shown in Fig. 8, the front of the speaker box 1 can be covered with the pressing
member 3 as shown in Fig. 8 or a sheet attached with two pressing members 2 1-2 1-2 pressing
members. Since the shape of the pressing member 3 can be made arbitrary regardless of the
shape of the frame 2a of the speaker unit 2, using this pressing member 3 as a design processing
material improves the appearance of the speaker system by K, The mechanical strength of the
speaker system (speaker box) can be improved. As described above, according to the present
invention, the rising edge t of the frame of the speaker unit fitted to the front of the speaker unit

speaker box Since the plunge fitting enables the sealing degree between the speaker unit and the
speaker box to be improved by the plunge fitting, it is possible to generate a high quality sound
by reducing air leakage pipes, and Since the outer periphery of the frame of the speaker unit is
fitted and fixed in a state of being fitted between the speaker box and the pressing member, its
mounting strength is contrasted with that fixed by screwing at several places as in the prior art
There is no risk that the mountings will come loose due to air vibration in the speaker You can
high-quality sound 會得Ru, further Subi?
It is possible to provide a speaker unit with an excellent appearance because speaker gold
mounting can be performed without sticking to the shape of the 9th car frame.
