[Detailed description of the invention] * The speaker * is a speaker, in particular, the edge around
the diaphragm skins the improved speaker. The edge around the diaphragm of the speaker
always holds the diaphragm on the center ring of the speaker, and when the vibration #i slides,
the baffle action of -1 reduces the sound wave of antiphase after the moving plate @ J Therefore,
this edge has the role of a large power of 1E: goodness or badness of the speaker, such as 7
(“1” characteristic, low 廿 characteristic, etc. It has a drawback that it is simmering by an anticorruption wave from a plate tube side supporting part, etc., and it is easy to produce IL + and
valleys in the midrange region in the midrange region. (1) In addition, the support of the edge
becomes -Jln and the bass co-shooting cycle number becomes high, and the electrodynamic of
the bass reproduction is commanded. Therefore, in order to reduce bad habits due to reflected
waves, the concept of the free end of the shooting board is increased as a so-called free edge in
the v19 speaker. As the material of the edge, cloth 1-Mart Brenpe sponge rubber, soft skin, etc.,
which are large in size → large in size and large in internal loss, are used to support the vibration

system of the speaker as softly as possible to reduce stiffness. I have to polish. However, if the
vibration system is made too soft, the shape retention property will be deformed and it will cause
side digging and it will be distorted and the diaphragm will come out of the correct position and
the abnormal sound will be emitted while the moon is passing through. There is a drawback to
doing. As it is very confusing to make these problems by the edge of the structure shown in the
conventional FIG. Other methods, such as a so-called two-ring damper method, a threading lever,
etc. have been devised. According to such a method, the edge can only make a powerful action on
the car, and the inertia can be increased, and the shadow j due to the father, the reflected wave,
etc. can be compared (2) less. However, it is the present situation that even in the various
systems of these conventional axes, the result which should be added to eliminate the abovementioned drawbacks can not be obtained. The present invention has been made to overcome
the above-mentioned disadvantages. Therefore, the purpose of the present invention is to make
the mobile version so-called free edge, and to make one side of this edge not be one-by-one. By
having it in mind, good hearing in medium and low tones is to provide a loudspeaker. The
invention will now be described according to the embodiment shown in the attached drawings.
Figures 1 and 2 show a practical example of the invention according to a 2t damper type speaker
and a threadcage type speaker by 1a; + 1 pair in total 7f, and the figure shows 1) A gift and a
voice coil (3) attached to the center (12) after the center (12) Consisting of two straight lines by
L1 dampers (4a) and (4b) It is inserted in).
-@ Inter-plate side part 6) (G, made of cloth, etc., I-shaped [·] edge (7) through the yoke part of the
front part light 1 of the support + HH through the edge (7) It is to be noted here that it is
embedded in the gap (t) formed between the two interleavers (9g) and (9h) provided in (8α) + 71. As clearly shown in the enlarged view of the main part in f'i FIG. 4, the diaphragm peripheral
portion (6) is not fixed but held with a slight margin in the intermittent bite. It is a point that is
nine. Interposition (9 tL), (9 h) cloth. It is a good idea that it is made of a complementary material
such as felt, sponge, rubber, and coffee. In the threading method at the 2nd t-line, a Nakasutogashi body is fixed at the tip of the anchorage fixed at the center of the 1st ring (ii). A plurality
of springs (2) respectively connected to a plurality of yarns a1 whose one end is fixed to an end
portion (6) of the intermediate body d1 at a d edge of the S plate peripheral portion (6) There is.
The other same reference numerals indicate the same members as in FIG. 1, and so on. 5 to 7I
are enlarged sectional views of an essential part showing one example of the right of the speaker
according to the present invention. In the case of FIGS. 5 and 7 south, an intermediate insert (9c)
is provided between the inner insert (9cL) and the outer insert (9h). Two coughs (IQtL), (106)
and (4) are formed. Therefore, it is as shown in the figure that the tip of the diaphragm
peripheral portion (6) held in the gap is divided in two. And 6th and 7e! In the case of l, a
practical example is shown in which the flat end is made. The present invention is configured as
described above, and according to the present J '#, the tip of the edge (7) of the side of the
diaphragm is not fixed to the yoke (88). There is an advantage that the size is extremely large
and the stiffness is ideally reduced. Also, when it is determined that the interpersonal gap aQ or

parts around the diaphragm are uniformly mixed (Iili without reason) and the cedar cedar 1 +such as the opposite wave in the middle range is extremely small and the good medium sound
