BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a conventional
speaker, FIG. 2 is a plan view of a conventional passive diaphragm, FIG. 3 is a partial crosssectional view of the speaker of the present invention, and FIG. Plan view. 1 is a foamed resin, 2,
3 ... end, 4 and 6 are diaphragms, 5 is a frame.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a peripheral
mounting structure of a pan / blank plane moving plate disposed on the front of a driving
diaphragm. Conventionally, as shown in FIG. 1, the center pole 7, the magnet 8, and the plate 9
constitute a magnetic circuit, the frame 5 is attached to the upper surface of the plate 9, and the
center pole 7 and the plate 9 form a magnetic gap. The dampers 11 are arranged so that the
voice coil 100 winding portion is disposed at the center of the magnetic gap, the voice coil IO is
suspended at the center of the frusto-conical diaphragm 4, and the outer peripheral edge is
adhered to the inner bottom of the frame 5. The voice coil 10 is held at the center, the peripheral
portion of the diaphragm 4 is adhered to the outer peripheral edge of the frame 5, and the
dustproof cap 12 is adhered to the central portion of the diaphragm 4. An arc shape having a flat
bumper diaphragm 6 made of a light material such as paper or aluminum arranged on the front
surface of the diaphragm 4 and projecting outward or inward between the peripheral portion of
the diaphragm diaphragm 6 and the outer edge of the frame 5 Both end faces of a work having a
cross section and a die 3 are attached and inserted in the vibration direction. In this case, since
both ends of the edge 3 were cut off at an angle and pasted as shown in FIG. 2, there is a
disadvantage that the compliance of this portion becomes small due to the adhesive and the
stretchability. If it is an arc, there is a drawback that causes the sagging of the diaphragm. 7 'The
present invention was devised to eliminate the above-mentioned drawbacks, and to explain the
embodiment shown in the drawings, as shown in FIG. 3 and FIG. Is the same as the conventional
example, but it is between the outer edge of the lens 5 to which the peripheral portion of the
drive diaphragm 4 is attached and the peripheral portion of the flat diaphragm 6 disposed on the
front surface of the diaphragm 4. Eno / 20 with an arced cross-section that protrudes outward or
inward is attached to the end of the speaker and inserted in the direction of vibration. This is an
age of a speaker in which a foam resin 1 such as urethane foam is fixed to each corner of the
seam 2 of the case 2 and the end face of the edge 2 is stuck. Since the present invention is
structured as described above, the sagging of the diaphragm can be prevented by fixing each
corner of the diaphragm 6 with a foamed resin such as urethane foam and making it extensible
in the vibration direction. Can. The present invention includes a speaker-7 stem that mounts a
driving speaker in a speaker box, and has a speaker flat diaphragm and a speaker flat diaphragm
with the same structure at the front of the driving speaker and the opening of the speaker box. .
