The present invention relates to the improvement of a cone type speaker emitting a blue tatami
mat by piston movement of a cone, and in particular, the prevention of linearity O tampering and
edge resonance by improving the edge of a heavy cone heavy speaker It is an attempt to measure
energy. Conventionally, various cone-shaped speakers have been provided, but the edges used
for the wedge-cone-shaped sneakers are usually formed and processed in advance into a fixed
shape having a wave shape and a semicircular force. Therefore, the elastic force of the edge is
limited, and the edge does not change linearly with the piston movement of the cone, causing the
deformation of the wedge edge, which has a disadvantage of generating gold. The present
invention ameliorates the above-mentioned drawbacks and aims to provide a novel cone-shaped
loudspeaker edge which follows the piston movement of the cone in a completely linear manner
and does not generate distortion. Hereinafter, based on an embodiment of an edge of a cone type
speaker according to the present invention, it will be described with reference to the drawings.
FIG. 1 is a perspective view showing a rubber which is a raw material of an edge and a
stretchable elastic 'ilj of synthetic am force. The elastic material (1) is a band-like 4 having a
certain width and thickness, so that when both ends are connected to form a ring, it is just
between the outer circumference of the speaker cone and the inner circumference of 7 frames
Have a length. When the elastic material fll is connected to the ring of the elastic material fll
sufficiently wider than the distance between the cone of the speaker and the frame, and one side
(1a) in the longitudinal direction is connected to the frame and the other side (1b) is connected to
the cone, Make it possible to form a U-shaped cross section. Therefore, the stiffness is set to a
predetermined value. FIG. 2 shows an embodiment in which the elastic material (1) t shown in
FIG. 1 is used as an edge of a speaker made of I-n. (鵞) is a frame of the speaker, + lla cone, (4) Is
an edge. The edge of the edge (4) is fixed at 7 A in the figure A (fixed on the other side at 1 II-B in
the figure B) 1 °-: / fil and m fixed-at ′ ′ 1 · ′ ′)) -/ 141 f1 The main body portion is made
of a substantially U-shaped cross section. So one side of the main part of the edge (4), frame (!
And the other side surface of the body portion of the edge is imaged as the outer flat surface of
the cone (3) and is flat. 7レーム(! 1 and the flat part of the cone (3) (deeper than the flat th
part of the ship, and the length of the flat part of the frame (corn and cone 1 $ 1 makes the
straightness of the edge (4) A good range -1, that is, a range of less than 11 blue tatami mats
emanating from the cone / speaker is determined.
Accordingly, the piston movement of the cone is equalized, and the collar 4) 4 performs so-called
caterpillar movement as shown in FIG. 4, and movement according to the movement t & of the
cone without changing its shape. Fig. 4H) shows the state of the edge 14 in the stationary state of
the cone (3). In this state, when the cone (3) moves forward, the edge (4) looks like the 4th
mouth) and Become. Also, in the state of the fourth tool), when the cone 1B + moves to the
cutting edge, the edge (41 becomes like the fourth yoke 9). II! As is apparent from the 41m
baro, the cone (31 does not move at all, so that the shape of the edge does not change, so there is
no line of force that deforms the cone, so there is no generation of gold. In the embodiment
shown in the figure, one side of the edge 14i is directly fixed to the frame (2 :) and the other gs of
the edge (4) is directly fixed to the cone (3) and the flat portion of the frame is directly used. A
flat portion is formed on the edge (4) and the surface S of the cone (3) is directly used to form an
edge (4 (a flat 1 klh is formed to obtain a public expense edge structure). However, as shown in
the turtle 6 figure, you may make the edge part early. 5th i11! 1 shows another embodiment of
the edge of a cone certificate speaker according to the present invention,] 5 (6) A frame (a
separate first flat member is fixed to the frame, and another frame is also to the cable 43) The
second flat member (6) is a fixed cocoon. Thus, one company of edge (4) is fixed to the inner side
member ii + of the crucible 1 and 11 other companies of the edge t4 + are fixed to the second
ridge member, and the substantially U shape of the edge IU is obtained. In order to form the
above-mentioned $ 1 and the second flat members (6) and (6) 0 as shown in FIG. Because it is a
public expense edifice built without processing, the cones and frames used in the conventional
speakers can be used as they are, and there is a point where compatibility is obtained. 0 and 2 kl
L shown! The edge of the cone speaker of the OIKSm rice is of course displaceable of the cone,
which is of course possible to exchange any part of the example with one another, for example by
setting a plane member only on the L frame. In order to improve the linearity with respect to the
edge, the edge of-is made wide, but the edge of the edge is made to be wide I had it. Since the end
of the cone-shaped speaker according to the present invention uses a band-shaped elastic
material which is not molded, it has the ability to reduce its width by jt without losing its axiality.
The combination of its resistance and-'can make it possible for the edge resonant tube to not
form at all.
As described above, the present invention is characterized in that the edge is formed using a 71shaped 0-elastic -1, -1 material subjected to a cone-shaped screw "0" "1 according to the present
*; draft. Moreover, since the frame, the cone, and the square U-shaped with flat portion are
formed by using a frame, a cone, and a flat square village, the cone-shaped speaker having
excellent ui linearity can be obtained. 4-Easy-to-use drinking light Fig. 1 is an oblique view of an
