報参照）。(b) Prior Art Conventionally, as shown in FIG. 4, a plurality of tongue pieces 4a provided at the end of a bent portion 4b of a punching net 4 are attached to a resin speaker panel 1 having speaker mounting holes 2 and 3. The punching net is fitted into the mounting groove 1a provided around the speaker mounting portion 1b, and ultrasonic vibration is applied by an ultrasonic vibration generator to weld the tongue piece 4a of the punching net 4 and the mounting groove 1a of the speaker panel 1. 4 and the speaker panel 1 are fixed together (see Japanese Patent Laid-Open No. 143694/1983).

る。 Further, as shown in FIG. 5, the end of the bent portion 4b of the punching net 4 is flattened, adhesive 5 is applied to the mounting groove 1a provided around the speaker mounting portion 1b of the speaker panel 1, and the punching net 4 is made flat. It is also known that the end of the bent portion 4b of the net 4 is inserted into the mounting groove 1a and bonded. However, in the case of ultrasonic welding, the tongue piece of the bent part of the punching net is immersed in the melted resin due to the heat generated by the ultrasonic vibration.
Since the punching net is set to penetrate approximately 1.5 mm, if this punching net is adhesively fixed to the speaker panel, the punching net may protrude too far in front of the speaker panel, causing an appearance problem.
従つて、超音波溶着固定用のパンチングネツト
とスピーカパネルを用いて、接着固定することが
困難なため、パンチングネツトとスピーカパネル
を生産方法に合わせてそれぞれ別個に準備する必
要があり、割高になると共にフレシキブルな生産
体制をとることが出来なかつた。 Therefore, it is difficult to use punching nets and speaker panels for ultrasonic welding and fixation, so it is necessary to prepare the punching nets and speaker panels separately according to the production method, which is expensive. Therefore, it was not possible to establish a flexible production system.
(ハ) 考案が解決しようとする問題点
本考案は、パンチングネツトと取付部材を溶着
用と接着用にそれぞれ別個に準備することなく、
一種類の組み合わせで溶着と接着の二つの生産方
法を可能にするものである。(c) Problems to be solved by the invention The invention eliminates the need to separately prepare punching nets and mounting members for welding and adhesion.
This allows two production methods, welding and adhesion, to be used in one combination.

られている。(d) Means for solving the problem A metal punching net is provided with a bent portion around its entire circumference, and the bent portion has a plurality of tongues. The resin mounting member is provided with a first groove having a width sufficiently larger than the thickness of the punching net at a position corresponding to the tongue piece, and a first groove shallower than the first groove and having a width equal to the thickness of the punching net. A plurality of second grooves each having at least a narrow portion of approximately the same or slightly greater width are provided in succession.

Insert the tongue piece of the punching net into the second groove of the mounting member and connect the tongue piece and the second groove.
It is configured to weld the grooves of.

切替えが簡単にできる。(E) Effect The second groove for welding fixation is larger than the first groove for adhesive fixation.
Since the groove is shallow, the punching net is attached to the mounting member in the same manner whether the punching net is fixed by adhesive or by welding. Since a plurality of first grooves and a plurality of second grooves are provided alternately, it is possible to easily switch between adhesive fixing and welding fixation by changing the groove into which the tongue piece is inserted.
(ヘ) 実施例
以下本考案の実施例を、第１図〜第３図に従つ

線に対し非対称に設けられている。 A speaker panel 1 having speaker mounting holes 2 and 3 is made of resin, and a plurality of first grooves 1a 1 and a plurality of second grooves 1a 2 are provided alternately and consecutively around the speaker mounting portion 1b. ing. first groove 1
A1 corresponds to the tongue piece 4a of the metal punching net, and three pieces are placed on the short side 1c side of the mounting groove of the rectangular speaker panel 1, and four pieces are placed on the long side 1d side, with respect to the center line of each side. It is arranged asymmetrically.

ングネツト４の舌片４ａを対向するスピーカパネ
ル１の第２の溝１a2に嵌挿する。 When the punching net 4 is welded and fixed to the speaker panel 1, the punching net 4 is turned upside down. In this way, since the tongue piece 4a of the punching net 4 and the first groove 1a1 of the speaker panel 1 are provided asymmetrically with respect to the center line of each side, the first groove 1a1 of the speaker panel 1
The tongue piece 4a of the punching net 4 , which had been opposed to the groove 1a1 of the speaker panel 1, does not face the first groove 1a1 of the speaker panel 1, but faces the second groove 1a2 . Next, the tongue piece 4a of the punching net 4 is inserted into the second groove 1a2 of the opposing speaker panel 1.
この後、押圧体（図示せず）をパンチングネツ

は溶着固定される。 Thereafter, a pressing body (not shown) is pressed onto the punching net 4, and an ultrasonic vibration generator (not shown) is operated to cause the pressing body to vibrate up and down approximately 15,000 times per second. The tongue piece 4a of the punching net 4 and the second groove 1a 2 of the speaker panel 1
generates frictional heat at the contact area and melts the resin. As a result, the punching net 4 is inserted into the second groove 1a2 of the speaker panel 1 by the tongue length D (approximately 1.5 mm).
mm), and when the ultrasonic vibration stops, the resin solidifies and connects the punching net 4 and speaker panel 1.
is fixed by welding.

ピーカパネル１に対する１は接着固定の場合と変
わることがない。 In this way, the difference D in depth between the first groove 1a 1 and the second groove 1a 2 is set to be the same as the length of the tongue piece 4a, and by ultrasonic welding, the tongue piece 4a is entirely inserted into the resin ( Since the length D) penetrates, the distance 1 of the punching net 4 to the speaker panel 1 is the same as in the case of adhesive fixation.

に比べ作業性がよい。 FIG. 2C is a diagram showing the shape of the groove in another embodiment,
The second groove 1a 2 is provided with a wide portion 1a 3 communicating with the narrow portion on which the bent portion 4b of the punching net 4 or the end edge of the tongue piece 4a abuts. When the punching net 4 is adhesively fixed to the speaker panel 1, when adhesive is applied to the wide portion 1a3 as well as the first groove 1a1 , the adhesive flows into the second groove 1a2 as well. Next, the tongue piece 4a of the punching net 4
into the first groove 1a 1 of the corresponding speaker panel 1 and glue it, and the other part of the bent part 4b end surface of the punching net other than the tongue piece 4a is inserted into the second groove 1a 2 and the wide part 1a 3 . Glue. This way, the first
The fixation is more reliable than gluing only groove 1a 1 , and since the adhesive only needs to be applied to the entire circumference of the groove on the speaker panel, it is easier to work with than when it is applied only to the first groove 1. .

それぞれ交互に連続して設けられている。 FIG. 3 is a diagram showing another embodiment in which a circular punching net is fixed to a circular groove of a speaker panel. A circular metal punching net 4 is provided with a plurality of tongue pieces 4a at a bent portion 4b extending over the entire circumference. The speaker panel 1 having the speaker mounting hole 3 is made of resin, and the speaker mounting portion 1b is provided with the above-mentioned first grooves 1a 1 and second grooves 1a 2 alternately and continuously.

効果を奏することができる。 It goes without saying that the shape of the punching net of the present invention is not limited to the aforementioned rectangular or circular shape, and that the mounting member is not limited to the speaker panel. Furthermore, similar effects can be achieved in welding other than ultrasonic welding (for example, welding by high frequency induction heating, etc.).
