RADIO RECEIVING STRUCTURE
Arno E. Tauscher, Chicago, Ill.
Application October 6, 1937, Serial N0. 167,520
4 Claims. (Cl. 181—31)
The invention has for its object to provide a
radio receiving or sound transmitting structure
which will transmit to the ear of the listener
the sounds transmitted from the broadcasting
5 station to the receiving structure as the same are
delivered to the microphone of the broadcasting
station, without change in register or quality
Without necessitating any tone quality or register
adjusments of the receiving structure.
A further object of the invention is to provide
10
a receiving and sound transmitting structure
presenting the advantages hereinabove pointed
out which is relatively small, compact and cheap
and may be embodied in furnishing units of a
15 home.
A suitable and exemplary embodiment of the
invention is illustrated in the accompanying
drawing, wherein:
Fig. l is a central vertical sectional view, part
ly in elevation, illustrating a radio receiving
structure constructed in accordance with the in
Vention.
Fig. 2 is a bottom plan view of the set of reso
nance or sounding boards included in the set
25 shown in Fig. 1.
Fig. 3 is a View‘ in elevation of a receiving set
of the invention embodied in a lamp.
The structure of this invention comprises a
bowl I, preferably composed of sheet metal, but
which may be made of other materials possessing
characteristics necessary to produce the same or
substantially the same result as the metallic bowl
shown, said bowl constituting a container and
support for an inner metallic member 2. The
35 latter is of truncated cone shape and it also is
preferably composed of sheet metal and is
equipped at its upper end with an outwardly
projecting ?ange 3 which rests upon and. is
suitably secured to the similar ?ange 4 of the
40 bowl I, and which is also equipped at its lower
end with an outwardly projecting annular ?ange
5, the circumferential ?ange of said member 2
being equipped at regular intervals with out
wardly projecting beads 6 which act to stiifen the
45 same to reduce its tendency to vibrate.
Secured to the ?ange 5 is a dished skeleton
sheet-metal member 1 which may be deemed to
constitute a foraminous bottom wall of the mem
ber 2 and to which the conventional electrically
responsive mechanism common to all radio re
ceiving sets is secured for support, said mecha
nism being indicated by reference numerals 8
and 9. The electric wiring, (not shown) which
connects elements 8 and 9 with the condenser
55 and tubes of any conventional radio receiving
set, passes through a central opening H3 in the
bottom of the bowl I, the device of the present
invention being in the nature of an attachment
to a conventional type of receiving set, the cas
ing of which houses the condenser and tubes and
carries the control devices common to receiving
sets.
The member 2 and all parts carried thereby
are spaced from the walls of the bowl I , the latter
having a slightly tapered circumferential wall 10
and a dished bottom wall which is ?at at its lower
most middle portion H and is ?ared upwardly
to meet said circumferential wall as shown at E2.
The resonance or sounding boards l3, Iii, l5,
and I6, composed of suitable wood or other ma
terial possessing the same or equivalent charac~
teristics, are coupled with each other in spaced
apart and parallel relation to each other by
means of sheet metal brackets H, the uppermost
board 13 being of slightly larger diameter than i
the board M and the latter being of slightly
larger diameter than the board IS, the lower
most board I6 being of much smaller diameter
than the board l5. All of said boards are pref
erably circular and are concentric with each
other, the peripheral edges of all the same being
spaced from and disposed concentric with the
circumferential wall of the member 2. The
board [6 lies below the ?ange 5 of the member
2 and is spaced from the member 1.
.30
The diaphragm [8 of the type common to and
commonly termed the “horn” or loud-speaker
of a radio receiving set, is supported peripherally
upon the peripheral edge portion of the said
member 1 and is clamped between the latter and
the ?ange 5 of the member 2, the coupling ele
ments such as the bolts l9 being passed through
the said peripheral portion of said diaphragm.
_The tube and condenser containing case 20 of
a conventional receiving set is shown in Fig. 3 4.0
and is equipped with the manually operable
control buttons 2| and 22, the said elements 8
and 9 and the diaphragm l8 being transferred
from said casing 20 to the structure which in
cludes the bowl I, member 2 and the several parts 45
connected with the latter.
The said bowl I may be disposed for support
upon the top wall of the casing 20 or may project
partly into the same and, preferably, when em
bodied in a lamp support, said bowl I is housed
by a casing 23 which, in turn, supports the stand
ard or stem 24 of the lamp. The top wall of the
casing 23 is preferably foraminous, but is not
speci?cally illustrated to show this as such illus~
tration is deemed to be super?uous.

In actual use the structure of this invention
effects a very appreciable improvement in tone
and register of sounds transmitted to and
pered wall spaced from the surrounding wall of
said bowl, conventional electrically responsive
through it from the diaphragm I8, the tones
sound transmitting means, including the conven
tional diaphragm constituting a part thereof,
being far more round and smooth and devoid of
the harshness that is quite common to radio re
mounted upon the lower end of said peripheral
wall of said member and contained within the
ceiving sets.
bottom portion of said bowl, and a plurality of
spaced apart parallel sounding boards mounted
within the last-named member and having their
peripheral edges spaced from the surrounding 10
wall thereof and all of said boards being sub
stantially concentric with and opposed to and
spaced from said diaphragm.
3. A structure of the type speci?ed comprising
a bowl, a sounding board containing and sup 15
porting member mounted within the upper portion of said bowl and supported upon the top of
the latter, said member including a tapered pe
ripheral wall spaced from the surrounding wall
of said bowl, conventional electrically responsive 20
sound transmitting means including the conven
tional diaphragm constituting a part thereof,
It is believed that the several
boards I3-l6 of different dimensions are re
sponsive respectively in different degree to tones
10 from deep base to high treble and by their com
bined vibrations responsively to the vibrations of
the diaphragm 18 correct inaccurate sound
transmissions of the latter with respect to pre
dominance of tones in base register as opposed to
15 middle or treble register and vice-versa and
causing all tones in the several registers to be
transmitted to the ear of the listener in their
true respective values.
The members I and 2 are vibrated responsively
20 to vibrations of the diaphragm l8 in different
degree than the boards or disks l3 to 16 inclusive
and vary the tone quality resulting from the
combined action of the diaphragm l8 and said
boards l3 to IE inclusive, the latter being se
cured to and suspended from the flange 3 of the
member I by means of the brackets 25.
Practice has demonstrated that the ribs 6 of
the member 2 have a decided influence upon the
mounted upon the lower end of said member and
contained within the bottom portion of said bowl
and a plurality of sounding boards of respec 25
tively different diameters disposed in spaced
tone quality of the structure, in that, if omitted,
apart and parallel relation to each other and
substantially concentric with each other and
said diaphragm and spaced from and opposed to
the latter, said sounding boards mounted in and 30
impossible for the applicant to determine why.
Similarly, the shape of the bowl I appears to
affect the tone quality, the shape thereof as il
lustrated herein being selected as the result of
carried by said member and having their periph
eral edges spaced from the surrounding wall
thereof.
4. A structure of the type speci?ed comprising
many experiments, as best suited and adapted to
produce the desired result when composed of
sheet metal.
a bowl, a sounding board containing and sup 35
porting member mounted within the upper por
tion of said bowl and supported upon the top
of the latter, said member including a tapered
30 said tone-quality is affected adversely, but it is
I claim as my invention:
1. A structure of the type speci?ed comprising
40 a bowl, a sounding board containing and sup
porting member mounted within the upper por
tion of said bowl and supported upon the top
of the latter, said member presenting a peripheral
wall spaced from the surrounding wall of said
45 bowl, conventional electrically responsive sound
transmitting means, including the conventional
diaphragm constituting a part thereof, mounted
upon the lower end of the peripheral wall of said
member and contained within the bottom portion
50 of said bowl, and a plurality of spaced apart par
allel sounding boards mounted within the last
named member and having their peripheral edges
spaced from the surrounding wall thereof and all
of said boards spaced from and opposed to said
diaphragm.
2. A structure of the type speci?ed compris
ing a bowl, a sounding board containing and sup
porting member mounted within the upper por
tion of said bowl and supported upon the top of
60 the latter, said member including a peripheral ta
and longitudinally ribbed peripheral wall spaced
from the surrounding wall of said bowl, conven
tional electrically responsive sound transmitting
means, including the conventional diaphragm
constituting a part thereof, mounted upon the
lower end of said peripheral wall of said member
and contained within the bottom portion of said
bowl, and a plurality of sounding boards of re
spectively different diameters disposed in spaced
apart and parallel relation to each other and
substantially concentric with each other and said
diaphragm and said member and spaced from and
opposed to said diaphragm mounted in and car
ried by said member and having their peripheral
edges spaced from the surrounding wall thereof,
the smallest diameter sounding board of the
group being disposed nearest said diaphragm and
