BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing the structure of a conventional
speaker, and FIG. 2 is a view showing the structure of a speaker according to the present
invention. 1 is an elliptical diaphragm, 2 is a dustproof body, 3 is a corrugation, and 4 is a rigid
[Detailed description of the invention] Notes: 1 male to the adhesive structure of the dust-proof
body in the speaker equipped with a city-type portable temporary. The speaker structure of the
dustproof body in the speaker equipped with an oval diaphragm of Ot is as shown in FIG. 1B, the
dustproof body in the circular cone circumference of the central portion of the elliptical
diaphragm (+). 2) has a grooved surface bonded, but the bonding surface of the diaphragm (1)
and the dustproof body (2) is both oval / bent; Axes were formed in the observation part-it was
easy, adhesion was poor, and there was not enough protection and wrinkles. The present
invention is an improvement of such a conventional hole 6, and will be of benefit in the following.
@ 2 Fig. (・ ・ ・ ・ In C hill-01, it intersects with the elliptical tomb for the elliptical diaphragm
(1) and has a 90 ° angle with the central axis and '1-m 1 7 colkenyo / (3) to set this Colkane

μ μ μ μ μ ((2 2 1 There is no loss of J-consistencies, and the top effect is also light. In
addition, since the elliptical rhombus (1) is complemented by the rigid link (4), is it an ideal
imaging mode in which abnormal vibration such as burning of the diaphragm (flexion image a) is
suppressed 3 can get. Since it acts as a weight ring, it acts as a weight ring, and the diaphragm
finish increases, the lowest resonance wave number fo which determines the low frequency
generation limit, and the reproduction band is expanded. To have. In the following way, the
present invention: Ellipsoid cedar diaphragm ovality ml and crosses, and it can be used on a
plane with a ten night axis and a 90 ° angle less than 1114 river and elephant body. Bonding
the link and imposing the carcass on this rigid ring, there is no adhesion failure of the salt-proof
body. Insist on the interest rate, which will be expanded the reproduction band of.
