Next, the voice coil 4 and the coil bobbin 5 will be described before explaining the detailed relationship between the flange portions 33ca and 33 cab and the connecting portions 22a and 22b. The voice coil 4 is formed by, for example, spirally winding a conducting wire around a coil bobbin 5. The coil bobbin 5 is provided in a tubular shape, one end of the axial direction Y2 is inserted into the magnetic gap G, and the voice coil 4 is arranged in the magnetic gap G. When the voice coil 4 is energized in this state, a force that vibrates in the axial direction Y2 is generated in the voice coil 4. Further, in the coil bobbin 5, the other end of the axial direction Y2 is fixed to the diaphragm 6, and the vibration plate 6 is vibrated by the vibration generated in the voice coil 4.

As shown in FIG. 2, the leader lines 4a and 4b are drawn from the voice coil 4 on the diaphragm 6 side.

It is bent outward, bent inward in the middle, and is provided so as to gently approach the edge of the opening 21 toward the end.

Next, the details of the connecting portions 22a and 22b and the flange portions 33ca and 33cc will be described. By the way, as shown in FIGS. 5 (B) and 5 (C), the height H1 of the yoke body 33b of the portion where the flange portions 33ca and 33cc are projected is the portion where the flange portions 33ca and 33cc are not projected. The height of the yoke body 33b is lower than the height H2 of the flange portions 33ca and 33cc. Therefore, in the portion where the flange portions 33ca and 33cc are not provided, the magnetic gap G disappears from the plate 32, and the wider the range in which the flange portions 33ca and 33cc are not provided, the lower the magnetic flux density in the magnetic gap G. Become. However, as described above, it is necessary to provide a portion where the flange portions 33ca and 33cc are not provided because the leader wires 4a and 4b are passed through. One of the purposes of the present embodiment is to provide the flange portions 33ca and 33cc in as wide a range as possible within a range that does not interfere with the leader wires 4a and 4b, and to prevent a decrease in the magnetic flux density in the magnetic gap G.

Therefore, as shown in FIG. 3, the length of the flange portions 33ca and 33cb in the axial direction Y1 of the voice coil 4 described later is provided longer than the length of the connecting portions 22a and 22b in the axial direction Y1.

It is located on the connecting portion 22b side with respect to the end portion Ta12 of. The end portion Tb21 of the flange portion 33cc in contact with the connecting portion 22b on the leader side of the leader line 4a is located closer to the connecting portion 22a than the end portion Tb11 of the connecting portion 22b on the leader side of the leader line 4a.

Further, the end portion Tb22 on the terminal portion 26b side of the flange portion 33cc in contact with the connecting portion 22b (= the other connecting portion when the connecting portion 22a is used as one connecting portion) is the end on the terminal portion 26b side of the connecting portion 22b. It is located closer to the connecting portion 22a than the portion Tb12. The end Ta21 of the leader line 4b of the flange portion 33ca in contact with the connecting portion 22a is located closer to the connecting portion 22b than the end portion Ta11 of the leader line 4b of the connecting portion 22a on the leader side.

Further, the width W1 of the flange portions 33ca and 33cc is provided shorter than the width W2 of the connecting portions 22a and 22b, and therefore, the outer edges of the flange portions 33ca and 33cc near the ends Ta22 and Tb22 and the inner edge of the opening 21 A gap S is created between them. Then, the ends of the leader lines 4a and 4b can be passed through this gap S. Further, the ends of the leader wires 4a and 4b are connected to the terminal portions 26a and 26b by solder or the like, and the movement is restrained by the recesses 23a and 24b, so that the vibration of the voice coil 4 does not have much influence on the leader wires. The ends of 4a and 4b are less likely to vibrate. As a result, even if the end portions Ta22 and Tb22 on the terminal portions 26a and 26b sides of the flange portions 33ca and 33cc are brought closer to the connecting portions 22b and 22a side, they do not come into contact with the leader wires 4a and 4b.

Therefore, in the present embodiment, the distance L1 between the end portion Ta22 of the flange portion 33ca in contact with the connecting portion 22a on the terminal portion 26a side and the end portion Ta12 of the connecting portion 22a on the terminal portion 26a side is in contact with the connecting portion 22b.
