等の多くの欠点を有している。1 Background technology] There are two types of speaker edges: fixed edges, which are made from the same material as pulp cone paper and integrated with the pulp cone, and fixed edges, which are made from a different material from the cone paper and pasted together in a separate process. There are 7 Lienoges used. Among these materials, cloth, urethane, rubber, etc. are used as the free edge material, and after forming and cutting these sheet materials into a desired shape, they are adhered to the periphery of the diaphragm using an adhesive. As the adhesives 1 to 1 used for bonding here, paste r[, which is made by dissolving rubber-based, acrylic-based, or other resins in a solvent, has been conventionally used. In such solvent-based adhesives, the solid content solidifies as the solvent evaporates and scatters, producing adhesive strength. However, bonding using such solvent-based adhesives has many disadvantages. Fixing the point. That is, (1) it requires many steps such as uniform application of adhesive, bonding, and drying, and the drying process in particular takes time, making it difficult to mass produce and increasing costs; (2) using a solvent; Because of this, there is a big problem in terms of pollution1
(3) If the diaphragm or edge is made of polyolefin resin, polyester resin, holamide resin, etc., there is no suitable adhesive and chromic acid treatment,
It cannot be put into practical use without special pre-treatment such as surface oxidation in an oxidizing flame or plasma treatment. (5) local adhesion unevenness is likely to occur, and the quality of the adhesion is not stable.

We have proposed a method for joining a speaker diaphragm and an edge (Japanese Patent Application No. 57-40061). That is, this proposal aims at the fact that ultrasonic energy softens and melts thermoplastic resin relatively easily, and requires that at least one of the speaker diaphragm and its edges be made of thermoplastic resin, or Either one of the diaphragms contains or has a thermoplastic resin attached thereto, and ultrasonic energy is applied to the joint between the diaphragm and the edge to melt the thermoplastic resin, and then the diaphragm is cooled and solidified. This provided a method for integrally joining the edges.

惧れがあった。If such a bonding method is used, it is not necessary to use an adhesive, so each of the above disadvantages can be overcome. However, when the bonding area between the diaphragm and the edge is large, the ultrasonic energy may be applied uniformly to this bonded surface. There was a risk that the thermoplastic resin would not be sufficiently melted and the adhesive strength between the diaphragm and the edges would be insufficient.

面に基づいて説明する。The present invention has been made in view of this point, and provides a speaker that applies ultrasonic energy by providing a protrusion on the joint surface of the diaphragm, at least one of which is made of a thermoplastic resin, and a t-edge where they overlap. The present invention provides a method for joining a diaphragm and an edge. Hereinafter, the joining method according to the present invention will be explained based on the drawings.

際に必要な接合面の前処理は不要である。After that, the ultrasonic oscillator (1) is operated to generate the vibrator (2).
The ultrasonic energy from the diaphragm (7) is transmitted through the fixed horn (4) and the tool horn (3) to the joint between the diaphragm (7) and the edge (8), and the protrusion (71)ffl+ of the diaphragm (7)・・・
Alternatively, by applying ultrasonic energy to the protrusions (81) (8i)... of the edge (8), the protrusions 6DσD...
・Or by melting the thermoplastic resin of the protrusions (81'r (lih...), the protrusions (711711...
The part and the edge (8), or the protrusion of the edge (8) (
813 (811...) and the diaphragm (7) are completely brought into thermal contact.Then, by stopping the oscillation of vibration, the molten part is rapidly cooled and solidified, and the diaphragm (7) is brought into contact with the diaphragm (7). )
The overlapping portion of the edge (8) and the edge (8) are strongly joined. At this time, the ultrasonic welding time required to melt the resin is usually within 6 seconds at the longest, and the time required for the oscillation to stop and the melted resin to cool and solidify (holding time) is also 2 to 6 seconds.
The processing time is extremely short. There is still no adherend (71
(Since dirt such as dirt and oil adhering to the surface of 81 is shaken off by ultrasonic waves, there is no need to pre-treat the bonding surface when bonding with adhesive.
更に、工具ホーン（３）を被着体（７）（８）に圧着し

7) (8) can be joined with high accuracy without any deviation, and since no heat is generated in areas other than the welded part, there are advantages such as no deformation or deterioration of the product. The oscillation frequency is usually between 15 and 25 KIL (Z). Aluminum, iron, titanium, etc. are suitable materials for the tool horn (3).
次に、スピーカ振動板（７）のエツジ（８）との接合面

が望める。As is clear from the above explanation, the method of joining the speaker diaphragm and edge of the present invention has excellent effects such as extremely short working time and high productivity compared to the conventional method using adhesive. Even if the bonding area between the diaphragm and the edge is large, ultrasonic energy can be efficiently concentrated and applied to the unevenness formed on this bonding surface, resulting in a strong fusion bond between the diaphragm and the edge. Can be joined. In addition, the unevenness provided on the joint surface of the diaphragm or edge at the overlapped portion can be formed simultaneously with the diaphragm or edge using a heat press method, vacuum forming method, or injection molding method, greatly improving productivity. I can hope for it.
