BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view of an essential part of a
conventional ribbon type speaker. The second drawing is a cross-sectional view taken along line

[Detailed description of the invention] 4 · The device is a ribbon-shaped transport body discharge

wall unit 1t · y8 neutralization \ conventional iron ribbon speaker tl b, t11. . ^, 2 directions · · · As
shown here, the magnetism (01 is configured so that uniform magnetic flux acts on all types of
the ribbon diaphragm 1 fixed to the fixed terminal 31 + 31 at the mounting end 11 + 1 l The
both ends "l + 21 of the magnetic body" were parallel to the entire length of the ribbon vibrating
plate 1 with a slight gap at both ends of the bon type photographing plate 1 to be printed.
Therefore, the ribbon type diaphragm 1 has been swayed so that the mounting end of the ribbon
type diaphragm 12 page I, j and so on, l) Therefore, if there is a large input, especially when it
bends (there is also a U cut. Further, even when using an aluminum foil having a crimp on the
ribbon diaphragm 1, the material fatigue caused by repeated rapid bending as described above
often causes a crack to cause a functional failure. In the present invention, the above-mentioned
ribbon-type diaphragm 1 is used to prevent damage to the function and damage due to cracking.
Bon sy: See you in KxX. Next, we will explain the present invention V and the real 1 # example
with respect to the figure. In Fig. 3, 4N, solid, with "terminal" 1 + 31 attached end 1 □, 1. Ribbon

by dotted lines in FIG. 3-as shown in FIG. In the wide part of the corresponding interval, the flux

density is small or small, and in the other part, it is uniform as per page 3. Therefore, if the
ribbon type diaphragm lK current is passed, as shown by the dotted line in 4th y, both mounting
ends bend loosely at l ++ 11 needle and move to the same height as conventional one. Ribbon
type vibration i by strength of electric wave! In the case of NA of L1, repetition of bending at
both ends 11 + 11 is performed with the above-mentioned gentle bending angle, so cracking or
cutting l! T is hard to happen. In the embodiment of the present invention, the magnetic 10+ path
is constituted by partially cutting off both ends of the magnetic body corresponding to the
attachment end portion it of the diaphragm in the embodiment of the present invention. Do not
use this one with your body.
As described above, according to the present invention, the ribbon type vibration of the ribbon
type speaker, the i-plate can continue to exhibit its machine number sufficiently by preventing
the occurrence of the crack which has been a conventional defect. In addition, ten balances, 17
