DESCRIPTION JPS60259088
[0001]
According to the present invention, the speaker box is provided with a talk and a middle bass
speaker, the upper surface of the speaker box, etc. is provided with a hole in a direction
substantially perpendicular to the speaker direction, the sound path is bent in a direction
perpendicular to the hole, and the speaker There is a horn-like sound path that gradually
expands in the opening direction, has three or more front outlets, and the front of the speaker
box front cover is completely open, and the front of the mid-bass speaker has a wide center and
the cross section is of a radial type This speaker device is characterized in that a diffuser such as
a crosspiece is provided, whereby an ultra-compact, high-quality, low-cost speaker can be
obtained for large-sized sound quality, bass, and a small number of inputs. 1 and 2 show an
embodiment of the present invention, in which a treble 3 of a high range and a full range speaker
4 of a low to middle range are attached and opened on the front part 2 of the speaker box 1 That
is, a hole 6 is opened in a direction perpendicular to the opening direction of the speaker 3 ° 4
and covered with a horn-like sound path adapter 7 which is V-shaped and opened at the lower
side. The horn-like sound path 7 may be integrally provided in the speaker box 1 or may be
provided on the side of the speaker box 1 as shown in FIG. As shown in FIG. 2, the swirl 3 has a
cone diaphragm 8 adhered to a ring 9 made of phenol-impregnated paper or the like, and the
ring is adhered to a frame 10. As described above, by providing three speakers of the high range
and the middle range and the horn-like sound path in the single speaker box l, the fidelity of the
high range and the middle range is improved, and It has been experimentally confirmed that the
frequency range and the high frequency range are extended, the frequency characteristics are
extremely wide, and the sound quality is remarkably improved. In addition, the same frequency
improvement effect is obtained as the aperture is increased by 20 to 30%, and the same high
performance as a large speaker and a large box can be obtained even though the speaker box is
small. Furthermore, as shown in FIG. 1 and FIG. 1, by providing a front cover 10 having a

medium-wide crosspiece 8 and thin crosspieces 9 at its left and right sides only at the front
center of the low-midrange speaker 4, the high range is suppressed and the whole As the sound
becomes smooth, the sound disperses to the left and right, and the audible range becomes wider.
Also, since the high-range speaker 3 has no sound insulation material that easily attenuates highpitched sound and comes out straight, output drop of high-pitched sound is prevented from
falling and high-pitched high-range sound can be obtained. It is possible to obtain an amazing
high performance speaker system of 35 Hz to 20,000 Hz.
All other various modifications of the above embodiment are included in the present invention.
The present invention is a ground-breaking invention having many remarkable effects such as
expanding the frequency range of a speaker device and improving its characteristics and
increasing its output.
