reference number 141, fjl-Specification-Name of the pipe and speaker device Speakers are placed
inside the speaker box-installing a rotary plate and making the scale different A pipe-speaker
apparatus comprising a plurality of resonance pipes in the speaker box.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in
pipe-speaker devices. In general, it is far from the sound of nature if music played by an
electronic organ or the like is played directly from the speaker. One way to solve this problem is
to arrange one or more speakers in a hollow case, and to set up a large number of resonance
pipes different in scale from the case, and to provide a panoramic view of the sound coming from
the speakers. There is known a so-called pipe-speaker device that resonates with a pipe for
delivery. The prior art is shown in FIG. In the figure, 1 is a hollow case or speaker box, 2.2 'is a
speaker for bass and treble arranged inside the speaker box 1, 3 is planted through a member in
the upper part of the speaker box 1 There are a lot of resonances / (Eve. An object of the present
invention is to provide a pipe / speaker device which is expected to further improve the sound
effect as compared with the conventional device of this type. By the way, the applicant first made
a slit in the front of the speaker box, arranged a plurality of resonance pipes so as to face the
slynod, and provided an opening at a position opposed to the surinoto, and sent out from the
speaker We have proposed a pipe-speaker device in which the sound utilization rate is enhanced
by discharging the sound from the slit on the speaker box side and the openings on the side of
the resonance pipe through the openings on both the upper and lower sides of the pipe. .91722)).
Hereinafter, the present invention will be described in detail by way of an example of only this
kind of Eve-Speaker device, but it goes without saying that the present invention can also be
applied to the device shown in FIG. Absent. In FIG. 2 and FIG. 3, FIG. 2 is a perspective view when
the apparatus is viewed from the back side and a partial cutaway perspective view, and FIG. 3 is a
longitudinal sectional view thereof. As in the case of FIG. 1, 1 is a speaker box, 2 is a speaker, 3 is
a resonance pipe, and a rotary plate 4 which is rotated by a motor 5 is disposed inside the
speaker box 1. One or more speakers 2 are placed. An elongated slit 4 is formed in the lateral
surface of the side of the speaker box 1 so that the sound of the speaker 2 can be transmitted
from the slit 4. The rows of resonance pipes 3 are arranged to be opposed to the slit 6 of the
speaker box 1, and the slits 6 and the phase 1. A hole (opening) 8 is provided on the wall of each
of the opposite pipes. Each of these resonances, the rows of pipes 3, are locked by means of
screws 8 to a suitable support plate 10. The power is omitted in the figure! The support plate 9
to which this resonance pipe row is brazed is fixed to the speaker box 1 by appropriate fittings.
In addition to the function of concealing the speaker box 1 and the resonance pipe 3 from the
listener, the supporting plate 9 also has the function of a decorative member of the device by
providing an appropriate decoration on the old surface thereof. Ru. Also, if the lead wire of the
speaker 2 is pulled out to the outside through, for example, a slip ring (? 0, the sound of the
speaker 2 comes out of the slit 6 of the speaker box 1 and a pipe facing the slit 6) It is introduced
into the pipe from the hole 7 on the 3 side-and is divided into upper and lower halves and
delivered from both the upper and lower ports of the resonating pipe. At this time, by causing the
motor 5 to rotate the rotary disc 4 ', the sound transmitted from the resonance pipe 3 becomes
strong and weak. Well, it has the same effect as tremolo. Although the illustrated embodiment is
an example in which a hole is provided in the wall of the pipe facing the slit-of the speaker box,
and the sound 'from the slit is guided to the pipe by the hole, each resonance pipe is The same
function and effect can be expected even if the gap is arranged linearly in the vertical direction
and a gap is provided between the two, and the gap is made to face the slit of the speaker box. In
this case, the upper and lower pipes may have different diameters. In addition, if necessary, slits
may be provided on the back of the speaker box so as to discharge unwanted sounds from the
As apparent from the above description, according to the pipe-speaker device according to the
present invention, the same effect as the tremolo can be obtained with the in-cylinder
configuration, and the sound effect is improved compared to the conventional device of this pair.
Be expected.
