Description 1, title of the invention
Flat coaxial speaker system
3. Detailed Description of the Invention The present invention relates to a planar coaxial speaker
system having a planar shaped pluggable. 0 As the planar coaxial speaker system has not been
commercialized at all, there is no one with a portable brace. However, taking the case of a twoway system in which a conventional cone-shaped speaker system is shown in FIG. 1 as an
example, the structure is such that the bass speaker B and the treble speaker C are arranged in
tandem in the cabinet A. At the same time, there are many cases in which a paddle blade D
having only the diaphragm without the magnetic circuit and the voice coil is disposed
immediately below the bass speaker B with the same size as the diaphragm of the loudspeaker B.
The above purpose of the pluggable D is to improve the bass characteristics by appropriately
selecting the mass and the compliance of the edge Da, but the purpose is to use the pluggable D
as a bass. Besides, it is also known to radiate middle tones ranging up to several hundred hertz.
However, although it is desirable that the originally higher sound be radiated only from the highpitched speaker C, the high-pitched speaker C is also radiated as described above because it is
also radiated from the paddle blade D as described above. In the case where the pluggable D is
spaced apart, there are two sound sources, resulting in deterioration of the sense of localization
or concentration of the sound image, which is a case of the 3-way system. It becomes more
remarkable. In this scrapping, in consideration of the above-mentioned drawbacks, it is possible
to coaxially arrange two or more types of planar speakers and a planar shaped pluggable
connector to improve the localization of the sound image and to miniaturize it. It is an object to
provide a possible planar coaxial loudspeaker system. Hereinafter, the tree lIN will be described
based on a perspective view showing one embodiment of the 2-way planar coaxial type bi-

EndPage: 1-car system of FIG. In the drawing, a cabinet 1, a high-tone flat speaker 2 having a
square flat diaphragm 2 m, a bass flat speaker having a triple-frame flat diaphragm 3 m, and the
side flat speaker 2.3 is not shown. It has a magnetic circuit and a voice coil. Reference numeral 4
denotes a paddle blade made only of a frame-shaped flat diaphragm 4a, which has no magnetic
circuit or voice coil. The high-tone flat speaker 2, the low-tone flat speaker 3, and the pluggable 4
are coaxial with the high-tone flat speaker 2 as the center with respect to the buckle of the
cabinet 1 and with the pack brace 4 at the outermost side. However, the bass flat speaker 3 may
be disposed at the outermost side.
In the figure, 5 is a frame, 6, 7, 8, 9, 10, 11 are the edges (suspensions /) of the flat diaphragms
21, 311 t 4 &, and 12. 13, 14 are frames 6 to 11 fixed to the frame 5. Gasket. Therefore, the
high-tone flat speaker 2 and the low-pitch flat speaker 3 coaxially disposed are respectively
driven by themselves to emit high-pitched and low-pitched sounds, and the patch brace 4
generates sound pressure in the cabinet 1. It is driven and resonates in the low range and raises
the entire range of the low range. The medium noise radiated from the patch brace 4 does not
have the possibility of deteriorating the sense of localization or the sense of concentration of the
sound image since the pace brace 4 is disposed coaxially with the flat loudspeaker 2 for highpitched sound. The shapes of the flat diaphragms 2a, 3a and 4m may be circular, oval or other
shapes. In this case, as shown in the figure, two or more types of flat speakers 2.3 and the paddle
blade 4 of the flat diaphragm 4a are coaxially arranged, and the radiation is emitted from the
paddle blade 4 The sound source is not separated from the sound from the flat speaker 2 that
emits the higher sound, so the sense of localization of the sound image is improved, and the
space factor can be well reduced in size 0
