本発明は、％＜リボン振動板を製造するのに最適なスピ
ーカ用振動板の・製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a speaker diaphragm that is optimal for manufacturing a %<ribbon diaphragm.
従来、例えばリボン振動板の１つとしてのベリリクム振

材料からなるリボン状の振動板ベース２゛を真空蒸着機
中の治具（図示せず）にセットし、之にベリリウムＢ・
を蒸着していた（第２図、１ｉ４３図参照）。Conventionally, for example, a berylicum diaphragm as one type of ribbon diaphragm was formed by shaking as shown in FIGS. 1 to 5. That is, as shown in Fig. 1, a ribbon-shaped diaphragm base 2'' made of a material such as aluminum or copper, on which a p-rue, a groove 2', and 2' arms are previously provided on the upper and lower sides, is placed in a vacuum evaporation machine. Set it in a jig (not shown) and add beryllium B.
(See Figure 2, Figure 1i43).
そして振動板ペース２゛がアルミニウムで形成されてい

振動部５を形成していた。As shown in Figure 5, aluminum and vapor-deposited beryllium B
A swing wJ plate made of a composite material with e was formed. First, when the diaphragm pace 2' is made of copper, it is heavy with ρ=8.9, so the diaphragm pace 2' is made of copper using an acid such as nitric acid or an alkali.
The copper part of ' was removed by machining and chiming to form the vibrating part 5 made of beryllium alone.
しかしながら、上記の如き製法においては振動板自体が
リボン状で長細い構造のため、蒸着時の加熱によ郵振動
板ペース２′が変形する。従って製品も変形することに

１本づつ治具へ取付けたシ、蒸麿後は取外さなければな
らないため、取付作業工数を多く必要とし、コスト高圧
なっていた。However, in the above manufacturing method, since the diaphragm itself has a long and ribbon-like structure, the diaphragm plate 2' is deformed by heating during vapor deposition. Therefore, the product will also be deformed. In addition, the diaphragm plates 2' must be attached to the jig one by one during steaming and must be removed after steaming, which requires a large number of installation work and increases costs.
本発明は上述の如き点に鑑みてなされたものであシその
目的とするところは蒸着を１度行うだけで多量のリボン
状の振動板が得られて生産能率が向上し、コストが低廉
となるとともに製品の変形がないスピーカ用振動板の製
造方法を提供するＯＫある。The present invention has been made in view of the above points, and its purpose is to obtain a large amount of ribbon-shaped diaphragms by performing vapor deposition only once, thereby improving production efficiency and reducing costs. It is OK to provide a method for manufacturing a speaker diaphragm that does not cause product deformation.
以下本発明の一実施例をｗＪ６図乃至第１３図に従って
説明する。なお説明にあ九っては各図とも図中の同一部
分ＦｉｌｌｉＪ−符号で示す。An embodiment of the present invention will be described below with reference to Figs. wJ6 to Fig. 13. For convenience of explanation, the same parts in each figure are indicated by FilliJ- symbols.
先ずｊ１１工程として、アルオニウム、銅等の金属材料
を用いて、数個の切離用のスリット３を等間隔に配置す

ス本体１を真空蒸着機（図示せず）内の治具にセットし
た後に真空蒸着機内を真空にする。２ム一は前記振動板
ペース単体２の上下に設けられたロールエツジ部、１ム
は連設部である。First, in the j11 step, a base body 1 in which a large number of diaphragm base units 2 are connected in series is made by arranging several cutting slits 3 at equal intervals using a metal material such as aluonium or copper. After setting it in a jig in a vacuum evaporator (not shown), the inside of the vacuum evaporator is evacuated. 2 M is a roll edge portion provided above and below the diaphragm pace unit 2, and 1 M is a continuous portion.
そして第２工程として、真空蒸着機内を′°加熱するこ
とによりベース本体１の数個の振動ベース単体２にベリ
リウムを真空蒸着して蒸着部５を形成する・この場合、
例えばｍ７図に示すように開口部６を有するマスク板７
を用いれば、ｓ８図に示すように％振動板ペース単体２
に対して寸法４の範囲でベリリウムＢ・の蒸着が行える
。Then, as a second step, beryllium is vacuum-deposited onto the several vibrating bases 2 of the base body 1 by heating the inside of the vacuum evaporator to form the evaporation portions 5. In this case,
For example, a mask plate 7 having an opening 6 as shown in figure m7.
If you use % diaphragm pace alone 2 as shown in figure s8
However, beryllium B can be deposited within the range of dimension 4.
さらに第３工機として、ベリリウム蒸着後、ベース単体

ペース本体１を切断する。Furthermore, as a third machine, after beryllium evaporation, several pickpockets,
Each pace main body 1 is cut in two directions ffi: the axial length direction X of the slit 3 and the directions Y and F perpendicular to the upper and lower portions of the slit 3.
この場合、ベース本体１がアルミニウムで形成されてい

動板を形成する。。In this case, if the base body 1 is made of aluminum, a beryllium diaphragm as a product may be formed up to this t, and if the base body 1 is made of copper, beryllium is vapor-deposited. A vibrating part of beryllium B is formed by etching the copper with nitric acid or an alkali, leaving a slight overlap part between part 5 and the copper, and then attaching the diaphragm paste 2 to the slit 3. teX ;
Cut at points Y and Y' to form a beryllium diaphragm. .

蒸着させてもよい。Moreover, what is shown in FIG. 10 is a third modification of the base body 1#, and in this modification, the distance between the diaphragm pace units 2 is set to MK, which is the same as in the example above, and the distance between the two diaphragm pace units 2. The reason for this is that when vapor depositing the L1 paste main body 1"Kperi+) lamb Be, #Mt is carried out by pressing the mask plate T' against the wall Tm' for separating the valley vapor part as shown in Figure 13. This is to make it easier to cut by forming an "M-deposited part" between adjacent single beryllium bodies. In each of the above embodiments, an example is shown in which beryllium B is used as the vapor-deposited metal on the base body 1.1', 1'' formed of aluminum and copper, but aluonium or magnesium may also be used as the vapor-deposited metal. In this case, since magnesium is very easy to recognize, it is necessary to perform magnesium evaporation treatment on the other side.
For this surface treatment, a resin may be coated, or aluminum may be further vapor-deposited on the magnesium vapor-deposited layer.
上述のように本発明は、数個の振励ベース単体が連設さ

ｆＫ多量のリボン状の振動板が得られる九め生Ｍ能率が
向上し、コストが低廉となる。As mentioned above, in the present invention, only a few vibration bases can be vapor-deposited on a base body connected in series and then cut.
A ribbon-shaped diaphragm with a large amount of fK can be obtained.The efficiency of the ninth M is improved, and the cost is reduced.
しかも薄い振動板ペース単体を数個、連設して振動板本
体を形成したから、剛性が強くなる。従うて真空疎着時
における加熱により変形することがない。Moreover, since the diaphragm body is formed by several thin diaphragm pace units connected in series, the rigidity is increased. Therefore, it will not be deformed by heating during vacuum adhesion.
