It has a structure in which a voice coil of the speaker is connected by a lead wire (commonly called a brocade wire having flexibility). The tip of the lead wire of such an input portion and the terminal plate are soldered, but the length of the lead wire does not interfere with the vibration of the vibration system of the speaker and causes extra resonance to generate noise. It must be given an appropriate length and shape so that it will not occur, and the soldering was a work requiring skill and labor.

ル等の部分は記載が省略されている。The terminal board used for the input terminal of the conventional speaker is required to maintain the positional relationship between the lead wire and the terminal board during the soldering work. Therefore, its structure is as shown in FIG. Substrate 9 made of a metal plate having a joint with 6
Further, it has a structure in which an insertion cutout portion 7 for inserting and holding the lead wire 5 and a cut-and-raised piece 8 for pressing and holding the end portion of the lead wire 5 are formed at a position apart from the insertion cutout portion 7. .
In order to connect the lead wire 5 to the terminal board, the same figure and FIG.
As shown in the cross section of the connecting portion, the lead wire 5 is inserted into the insertion cutout portion 7, is cut and raised along the surface of the base body 9 and is guided toward the piece 8, and the tip portion of the lead wire 5 is cut and raised. The lead wire 5 is held on the terminal plate so as to be sandwiched between the back surfaces of the strips 8.
Then, in that state, the lead wire 5 and the base body 9 are soldered using the solder 10. It should be noted that in FIG. 1 and FIG. 1 showing the embodiment, parts such as a voice coil and the like connected to the other end of the frame of the speaker to which the input terminal part is attached and the lead wire are omitted.
