[Detailed description of the invention] This ig tea is flat lI]] for the roaring climate for the edge! More particularly, it relates to an edge suitable for a square flat-vibration plate suspension. Ela / R is a regular posture with sicamo, 戟 戟 r speaker frame without interfering with the piston interlocking of the moving plate, and it has a function t to attach to the floor, and the root plating of ル is adopted Rolled type Etsun is the largest number of deep rivers in Japan. Axis, 1-/ 9 / Lele Figure 3 shows the state of the suspension of the J-plate in three-state, but any of these edges h at the roll edge, In the figure), the roll edge / roll city / a protrudes to the back side of the diaphragm, and the Etuntoυflan / b is fixed on the diaphragm of the cloth @jVci) 1 )) Schematically show the ones that have been placed on the back side of the diaphragm −. Also, in the figure <U), roll edge l's hula / di / b shakes! It is fixed on the copper surface of the JJ plate core, and the roll city / a protrudes on the front side of the pregnancy plate l. In particular, when the flat diaphragm is square, there is a lot of problems with the corner capital, the so-called edge of the four corners, and if only the four corners are stiffer than the other parts, the diaphragm's pisto / %% = '? In order to aid the use of the other members at the four corner portions, the one in which the periphery is closed is used. For example. In the figure 2'p (B), r, 弔, except for the edge l corresponding to the four corners, the portion was closed by the corner member 3 formed of a visco-elastic material The thing 2- is shown. Since the table N of the number of beats is not flat in the original metal at the edge shown in FIG. 1, the anterior chamber effect is generated to disturb the frequency characteristics, and the second factor and FIG. In the case of what is shown 11-05-2019 1 next, there will be 7 rasters, but since there is a contact portion between the edge / and the corner member 3, VC durability will be a problem when driven with a directional output over a long period of time. Also, in the assembly operation, the customer service is extremely troublesome. Therefore, the present invention aims at directly determining the intermittent point of the conventional edge described above, and for that purpose, the shape, size τ corresponding to the periphery of the square diaphragm is urethane foam. The groove is formed parallel to the straight line portion of the diaphragm at the edge, and the groove is formed on the extension leg of one diagonal line of the diaphragm at the four corner portions, On the other hand, both ends of the recessed groove are in communication with each other, and it is assumed that the formation of the shaft is in standby state. In the following, description will be given of @ 43 to 6 of the drawings in which the embodiment 9J of the present invention is applied. First of all, in the figure, the strikes // show the square flatcurved vibration & this shake. The old Etsunoru is placed around vl & ll, and is clipped to the slider frame 13 and supported. This edge 12 is continuous with the production of a semivibration plate //, and the urethane foam is pressed using a pair of upper and lower forming wedges to make a dent, slit-like concave neighbor, concave surface / s At the same time, it is possible to shake 17 、 at the same time, pump it out along each side of the +1 MI removal board, and う / フ レ ー ム i11 / 2a, /, 2b that is watering out with a scea frame / 3i white is also formed simultaneously, and a circle The part enshrined in the fusi / n house is fujnot 1 on the next side, h 狐 V on the front side, and ed + dlV (-A ") with the nu-nu method. Kiri Eji h / 2 C1 C11, τi in the length direction, and slit-like "s" in the center / q Kariji, in the corner capital of Ella / 翰 〆-C, flat [III shift F piece ii On the diagonal green line ridge length of 6C slit downward / 4fj 1-wide concave surface 15 covered) 1), slit downward groove / '1L7) both facing y direction groove 15 It is a regular condition. Materials such as 4 edges of this 1), M II stated σ t こ 1 t こ レ フ ー フ ー フ ー フ ー フ ー ′ ′ ′ ′ are integrally formed by pressing, and the edge portion / 2 c includes the sides of the plane diaphragm //. In particular, the old groove i 52 is formed at the corner of the edge portion 2 c and the extension line of the diagonal plate of the flat displacement plate − (, The flexibility of the edge is sufficiently reduced, and the slit concave groove l and the concave groove 15 are acid-formed by pressing with a forming die, so the warp bottom portion is dense in material, so air leakage is prevented. It is. Nao, I mentioned above, I explained the square pottery, or make a polyhedra at the 7th board of the plate 7 @ For example, if the pentagonal corner (r's center and corner The ic shadow is formed on the radiation connecting the, and the concave curve 75 is formed in the radiation stop. As is apparent from the above description, the four edges are continuous on the plane b-c-b-b-old, and are continuous six times, and the flat portion of the edge is 7272 in the same -j. Slit-shaped concave ridges are formed along the sides of the edge portion along the side of 10 l V 1 or V, and the edge portion r corner portion 1 is a VC four-core 5-kta line extending the radiation of the flat diaphragm. Since the four grooves of the above-mentioned concave groove are in communication with each other in the concave groove of this corner portion, the edge of the edge is not generated in the table 11-05-2019 2 1i11H of the edge without generating any anterior chamber effect. It keeps the straight edge and the corner part flexible enough, and it doesn't have to worry about processing it such as special ItC and embedding at the corner part, it also contributes to the same as the outside fitting of the speaker unit. 11-05-2019 3
