が得られないといつた欠点があつた。 In such a configuration, the vibration system must be constructed by attaching the weight ring 5 and the dust cap 6 to the diaphragm 3, which requires time and effort to assemble, resulting in poor productivity.
The weight ring 5 and the dust cap 6 tend to be eccentric due to poor adhesion, and the weight ring 5 and the dust cap 6 tend to be eccentric with respect to the diaphragm 3, which prevents the diaphragm 3 from vibrating correctly and making it impossible to obtain the desired characteristics. There were some drawbacks that I mentioned.
本発明は以上のような従来の欠点を除去するも

０の中間部に埋設固定されている。 The diaphragm 10 is manufactured by making paper from pulp fiber or the like, and a dust cap 12 which also serves as a weight ring is coupled to the upper surface of the central portion of the diaphragm 10. The dust cap 12 is made of metal or synthetic resin, and has a flange 14 with a number of small holes 13 formed around its periphery, as shown in FIGS. The flange 14 has a formed structure, and the flange 14 is connected to the diaphragm 1.
It is embedded and fixed in the middle part of 0.

is injected, and a first layer 19 is formed on a papermaking screen 17 as shown in FIG. Next, as shown in FIG. 8, the dust cap 12 shown in FIGS. 4 and 5 is positioned and set in the center of the first layer 19, and as shown in FIG. A paper-making material 20 mixed with is injected and paper-formed to form a second layer 21 on the first layer 19 as shown in FIG.
これを抄造装置１６より取出し、水分を除去し
て振動板１０を得る。 This is taken out from the paper making device 16 and water is removed to obtain the diaphragm 10.

びに方法とすることもできる。 In addition, although a paper-making type diaphragm 10 has been described, when two synthetic resin films are heated and their surfaces are bonded together in a molten state to form a cone shape, the dust cap 12 is incorporated and the flange 14 is attached to the film. It is also possible to adopt a structure and a method in which the flange 14 is buried between the flange 14 and the molten resin is poured into the small hole 13 of the flange 14 to join the flange 14.

用的価値の大なるものである。 Since the passive radiator of the present invention is constructed as described above, the dust cap is positioned and connected when the diaphragm is manufactured, so the process of assembling the passive radiator is the process of connecting the damper,
The diaphragm is significantly simplified as it only needs to be connected to the frame, which improves productivity and reduces costs.Furthermore, the diaphragm is well-balanced, without the possibility of the center of the dust cap and diaphragm being misaligned. It operates in a stable state and has stable characteristics, which is of great practical value.
