Shows each embodiment of the connection structure of the input terminal of the speaker of the second invention. FIG. 1 shows the overall structure of the connection structure of the input terminals of the speaker according to the first embodiment of the first invention, FIG. 2 shows the structure of the main part of the connection structure of the input terminals of the speaker of the second embodiment, FIG. 3 shows the structure of the main part of the connection structure of the input terminal of the speaker of the third embodiment, and FIG. 4 shows the structure of the main part of the connection structure of the input terminal of the speaker of the fourth embodiment. In the first embodiment of the first invention, as shown in FIG.
1, a pair of left and right conductive connection plate members 20 each having a substantially rectangular opening 21 formed at the end thereof and having a substantially T-shape in plan view are fixed. The opening 21 of the connecting plate 20 is formed by punching, and a downwardly protruding portion 22 protrudes downward from an outer edge thereof. On the other hand, in the printed circuit board 30, base ends 41 of a pair of left and right conductive spring members 40 bent into a substantially U shape are fitted into a pair of left and right holes 31 provided in the printed circuit board 30. It is fixed by soldering so as to be integrated with the printed circuit board 30 by dipping. The spring member 40 has an arm 42 extending from a base end 41 toward the speaker 10, and a front portion 43 of the arm 42 is bent upward in a substantially L-shape. In order to connect the input terminal 11 of the speaker 10 configured as described above and the printed circuit board 30, as shown in FIG. 1, the distal end portion 45 of the upward portion of the spring member 40 is bent downward in a mountain shape. The top 46
Is fitted into the opening 21 of the connecting plate 20, and the spring member 40 is connected to the connecting plate 20 in an elastic contact state by the elastic return force of the spring member 40, so that the connecting plate 20 and the spring member 40 are connected to each other. The input terminal 11 of the speaker 10 and the printed circuit board 30 are connected in a conductive state via the speaker. Furthermore, in this embodiment, the downwardly extending portion 22 is
Are formed on the inner surface of the hanging part 22,
The downwardly directed portion of the spring member 40 curved in a mountain-like manner is in elastic contact with the elastic return force. Note that the hanging portion 22 may not be provided, and the mountain-shaped spring member 40 may elastically contact the left and right edges of the opening 21. According to the connection structure of the input terminal of the speaker of the first embodiment, the input terminal 11 of the speaker 10 and the printed circuit board 30 include the connection plate 20 having the opening 21 and the spring member 40 fitted into the opening. Since the connection is made via a wire, there is no need to use a lead wire and a connector, the number of parts can be reduced, the structure can be simplified, the cost can be reduced, no extra space is required, and The conductivity can be improved. FIG.
Shows the main part of the connection structure of the input terminal of the speaker of the second embodiment. In this case, both edges 23 and 24 of the opening 21 of the connection plate 20 are
Are formed on the arc-shaped periphery so as to increase the contact area corresponding to the arc-shaped outer periphery. Furthermore, the connecting plate 20
The outer edge 24 has a hanging portion 22 projecting downward by punching. According to this connection structure, both arc-shaped peripheral portions 2 of the opening 21 of the connection plate 20 are formed.
Since the arc-shaped outer periphery of the spring member 40 is pressed against the 3, 24, the contact area is large, and the connection in the conductive state can be improved. Furthermore, on the inner surface of the hanging part 22,
Since the downward portion of the spring member 40 is pressed, the conductivity can be further improved. FIG. 3 shows a main part of the connection structure of the input terminals of the speaker according to the third embodiment, in which the opening 21 of the connection plate 20 is shown.
Hanging portions 22, 25 are formed to project downward from both edges 23, 24 by punching. According to this structure, both edges 23, 2 of the opening 21 of the spring member 40 are provided.
4 has downwards 22 and 25 formed downward.
Since the right and left downward portions downward from the mountain-shaped top portion 46 of the spring member 40 are pressed against the hanging portions 22 and 25 of both edges 23 and 24 of the opening 21 of the connection plate 20, respectively, the spring member The connection between the connection member 40 and the connecting plate 20 can be strengthened, the contact area can be increased, and the conductivity between both members can be improved.
FIG. 4 shows a main part of a connection structure of an input terminal of a speaker according to a fourth embodiment.
0 is formed in an elliptical shape in a plan view, and furthermore, the outer edge portion 23 is formed with a hanging portion 22 downward by punching molding.
Is formed. According to this structure, since both edges 23 and 24 of the opening 21 having an elliptical shape in a plan view have a substantially arc shape, the spring member 40 extends along the arc-shaped outer periphery of the spring member 40. Since they are pressed into contact with 23 and 24, the contact area is large and the conductivity can be improved. Further, the spring member 40 is also provided on the inner surface of the hanging portion 22.
Since the downward portion is pressed, the contact area is further increased, and the conductivity can be further improved. In the first invention, although not shown, it is needless to say that the hanging portion may be formed downward only by punching and molding only at the edge 24 inside the opening 21 of the connecting plate 20. Further, it is a matter of course that the hanging portion 22 may be directed upward to form an upright portion (not shown). FIG. 5 shows a connection structure of the input terminals of the speaker according to the first embodiment of the second invention, and FIG.
7 shows a main part of a connection structure of an input terminal of the speaker of the second embodiment, FIG. 7 shows a main part of a connection structure of an input terminal of the speaker of the third embodiment, and FIG. 8 shows an input of the speaker of the fourth embodiment.
