DESCRIPTION JPS521122
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side view showing a cross section of a part of
a conventional loudspeaker, FIG. 2 is an enlarged view of a junction between a cone paper and a
ring of FIG. 1, and FIG. FIG. 4A is a characteristic view of the speaker shown in FIG. 1 and FIG. 4B
is a characteristic view of the speaker according to the embodiment of the present invention. v

[Detailed description of the invention] This device is an improved Kil of super cloudy Sukika! する

corrugation, y is formed, and outside 1 l lilil I is self-attached to the frame by the mounting agent,
and the non-linearity of the edge part is improved, but accompanied by the vibration of cone
paper The vibration of the part of the corrugation is delayed in time and affects the cone paper
again, that is, a reflected wave is generated, the rough of the high region is noticeable during this
rounding, the Q of the rising of the low region becomes large, the W region (4) Narrow <, it is a
large obstacle sign when it is incorporated into the Subikanstem. Therefore, in order to improve
such a point, as shown in 1st and 2nd, solidify a layer of li [plastic ring (2) in the opening of 7
lam lu, and this ring (2) There is the one in which the outer peripheral part of the corn paper (3)
is joined to the inner peripheral part of the rubber paper with a rubber-based adhesive agent /
41. However, since the ring (2) is thin in this first bad condition, as shown in FIG. 2, one width of
the cone paper + 31 can not be sufficiently obtained, and the lowest resonance frequency (/,)
becomes high. It is difficult to The idea of Jin is focused on the above points, and it is possible to
reduce the influence of the reflected wave from the edge portion and to make the lowest
resonance frequency sufficiently low, and to provide a speaker. Hereinafter, the embodiment will
be described with reference to FIG. 5 and the following figures. (5) is a copying plate of a
speaker, and the outside W4iiI is bent downward to form an IP portion (5a). 7) Use the beast
made ring for the ring (6) to be fixed to the opening of the frame, among which ii ++ s are bent in
the downward direction, too! Form 6C6a). In this way, the terminal point of the vibration 4jLt5 +

蛾 糎 11i (Il &) made of 4 is positioned on the top surface of the fine line i 16 (6a) of the gummy
61, and that he is there and it is a triangular circle of 9 117 A rubber-based dump 1iI4t 71 is
applied to the circumferential groove to elastically bond the swing plate (5) and the ring (6).
From the above, it is sufficient to apply to the circle + t @ fl * constituted by the inclined portion
(5a) of the dump agent (7) company ti411 plate (5) and the inclined portion (6a) of the surface /
gut (6) Of course, it is easy to adjust the amount of the agent which can be applied to the child,
and furthermore, even with a great dumping agent, there is no fear that the back 1iiK of the copy
lever (5) will flow into it. In addition, only the dumping agent (7) is grown on the edge portion K
of the movable plate +51, and the above dumping agent i7 + K can be used even as a very soft
one, so that the dumping agent (71 It is possible to minimize the reflected wave, so that it is
possible to improve the middle-high range C) 4I property and reduce it simply.
Furthermore, since the part facing the peripheral end face of the% scale plate (5) is the
inclination @ (6a) of the ring 161, the allowable movement amount of the sliding plate 15+ in the
longitudinal direction and the lateral direction with respect to the ring 6). As a result, even if the
center shift with respect to the air flow path occurs, the correction can be easily realized, and the
amplitude can be made large, so that the minimum resonance frequency can be made sufficiently
low. It will be possible to broaden the bandwidth greatly. Furthermore, since it can be treated as
a share of the ring (6), the chamber can be made wider as compared with the outer diameter of
the snail plate 151, and moreover, since a large heat can be used for the magnet, You will be able
to reduce the cost of the fee-free IIQIt4 magnet without a fee. In the above embodiment, the
peripheral end faces of the ridge IIh 叡 (5) are nine as opposed to the inclined surface (6st) K of
the ring fork 6>. Absent. FIG. 4 (a) shows a characteristic diagram of the conventional speaker,
and FIG. 4 (b) shows a characteristic diagram of the speaker according to the present invention.
