DESCRIPTION JPS50146535
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross sectional end view showing a
conventional nondirectional speaker, FIG. 2 is a cross sectional end view showing one
embodiment of the present invention, and FIG. 3 is a cross section showing another embodiment
It is an end elevation. Es beika, 4 ... ... post ..., 5 ... ... reflector. Figure 1 Figure 2 Figure 3 1 79 1
Detailed Description of the Invention This invention is a chair of thermalized lI + l l l l l l l l l l l l l l
1 l l l l l l l l l l l l l l l l l l l l l l l. Attach the electric sneaker, d gauge 1, to the upper Rc1 part of
the kite binnet (2) filled with ht play (1), and attach a circular bowl-shaped reflector (5j ') to the
front of the 70 speaker by pillar 141K 0, ie this conventional billless homosexual sciker is a
reflector of the h writing shadow (51, to diffuse t coming out of the loudspeaker horizontally), so
that a circular-shaped reflection The accuracy of the correspondence with the shape of the unit (t
tv and one sensor +31 'is required, and the reflector 1 (01' is manually operated (to reduce the
cost by Because it is radiated by the divided vibration of the cone X3 which cone paper, the voice
coil 44ki-because it comes out from the central part, that is, it is easy to get out of the central
part of the reflector. Have a point . The non-directional speaker which pays attention to various
points of healthy rice such as mentioned above in this invention (-the same point is 11 power,
simple structure, good characteristics are obtained, and is advantageous also in view of cost) The
purpose of the present invention is to explain the example of the edge of this invention with
reference to FIG. 2 and FIG. 14. First, FIG. 2 shows the shape of the cone paper (3a) of the
speaker 31 in general. , And placed on the perforated support plate (3o) in the magnetic port
portion (3b), and the reflector (5) is flat. In other words, the conical reflectors used
conventionally are not! Then, it was made to perform release #g of sound in the horizontal
direction by the corn seven. In this case, the radiation is emitted from the vicinity of the voice coil
as in the prior art, or from the vicinity of the voice coil, or it is emitted directly to the horizontal
sword I'ffl according to the above-mentioned shape. There will be no sinking. Further, as
described above, since the reflector +51 is flat, it is advantageous in accuracy as compared to the

conventional thinness, and the cost can be reduced, and the cone paper portion and the reflector
Since adjustment of the characteristics can be easily made only by adjusting the spacing, the
characteristics can be improved, and the design becomes animated. Fig. 5 shows pillars HJ in the
perforated frame portion of the slider. The whole of one piece is attached to 1000 yen and a set
(2) in reverse of the conventional pole attachment, and the radiation of bamboo is done from the
back of paper of cone paper (HII), and the special reflector itself is completely eliminated It is a
thing. This storage is necessary for special improvement and no reflector is needed, so it is more
cost effective.
As described above, this invention is a device in which the central part of the cone paper bulges
outward at the opening of the cabinet and the cone ridge is wound around to provide a
substantial reflector. As in the case of C above, there is no damping, no distortion of the position
tag as described above C, and the characteristics are good, and the structure is simple and the
cost is also favorable.
