本考案はスピーカ用のリブ付き振動板に関する
ものである。[Detailed Description of the Invention] The present invention relates to a ribbed diaphragm for a speaker.
従来より、振動板の強度を増大させるため第１

As shown in the figure, reinforcing ribs 1 having a mountain-shaped or egg-shaped cross section are separately molded on the surface of the molded cone paper 11.

り、生産性も低いものであつた。 However, in the conventional type, not only is it extremely difficult to bond, but the adhesive part 13 is exposed on the surface, resulting in an unsightly appearance.Also, since the reinforcing ribs are separately molded, they must be made of a material that can be molded. Due to material limitations such as not being heavy, it was not possible to use a material with sufficiently high strength. In addition, high precision was required for the mold for molding the ribs and the mold for thermocompression, resulting in high costs and low productivity.

ある。 The object of the present invention is to provide a ribbed diaphragm that eliminates the above-mentioned drawbacks of the conventional diaphragm.

とは勿論である。図中６はエツジである。 The structure of the present invention will be explained with reference to FIGS. 2 to 4 together with examples. In the figures, 1 indicates the entire diaphragm, 2 indicates the diaphragm body, and 3 radially extends on the surface of the diaphragm body 2. It shows the reinforcing ribs provided. In the present invention, the diaphragm main body 2 is made of cone paper, and reinforcing ribs 3 with a mountain-shaped cross section are integrally molded on the cone paper by reverse paper making, and a flat reinforcing sheet 4 is pasted on the opening surface of the cone paper. Ru. In this case, if the triangular cross-sectional shape formed by the reinforcing rib 3 and the reinforcing sheet 4 has the relationship l 0 > l 1 = l 2 t 1 = t 2 as shown in FIG. Mechanically, its pressure resistance is the highest. Further, tapers 5 may be formed at both ends of the reinforcing ribs 3, and in this case, it is desirable that the angles match the angles of the reinforcing ribs 3. Since the reinforcing sheet 4 does not require any special molding, it can be made of any material. Although the diaphragm main body 2 described above is made of cone paper, it goes without saying that sheets made of various fiber materials may be press-molded. 6 in the figure is an edge.

強をより高めることができる。 According to the speaker diaphragm of the present invention, the reinforcing rib having a mountain-shaped cross section is formed integrally with the diaphragm main body, and a taper is formed at both ends of the reinforcing rib to match the oblique side angle of the reinforcing rib. Moreover, since the reinforcing sheet is pasted to the rear opening surface of the reinforcing rib, its strength is significantly increased, and the appearance is also excellent because the pasted portion is not exposed on the surface. In addition, since the reinforcing sheet is in the form of a flat plate, it is easy to attach the reinforcing sheet, and it does not matter what material it is made of; it can be made of paper or other materials with a high Young's modulus, such as sheets made of various synthetic resins. reinforcement can be further increased.
