DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotating speaker
of a 1'-child musical instrument in which a speaker is rotated to obtain a tremolo effect on a
'core' instrument such as a 'r' organ. . When tremolo effect is to be obtained by rotating this
rotating speaker, it is desirable to reduce the moment of the rotating system as much as possible.
Therefore, conventionally, it is necessary to rotate the digital circuit i [-which occupies most of
the weight of the speaker. I made it as close as possible to the axis. However, this alone is not
sufficient, and the shape of the rotating body must be taken into consideration, because the
shape of the rotating body does not make a mark · · · 2. This is because it causes load fluctuation
and noise. In addition, when using a “1” speaker as a one-turn speaker, so-called phase
interference, 2) occurs when 1 to 1 for point use, and low-frequency same-frequency
characteristics (·, − deteriorate significantly, Hir, i did not use a special speaker that closed the
cone section of the speaker. The first [21 uz, as an example of the conventional rotary speaker,
by transmitting the rotation of the motor l to the rotation / thin 3 by the belt 2, at this rotation @
3 by the bracket 4 and the screw 5: the speaker 6 which has been standardized It rotates and
tremolo effect is generated. In such a configuration, it is the phase interference of the speaker 6
that becomes 1% (1% is the phase interference of the speaker 6, and the ordinary cone paper lφ
(1 is the peak where the speaker is used) And cause the characteristic to be significantly

deteriorated, and therefore, there is a disadvantage that a special speaker having a closed back
side of the cone paper to prevent phase interference must be conveniently used. Furthermore,
depending on the shape of the speaker, if the air resistance during rotation is subject to noise, it
causes noise, and the motor is also large (3i load). This notion is intended to eliminate such
drawbacks, and will be clarified below by the facts and remors shown in Fig. 2 and Fig. 3. The
second A is the rotating speaker It! In the 'I' 7I plan view, FIG. 3 shows its substantially circular
node-like shape ['turned-no-' (current view). In these weirs, 10 is a substantially cylindrical nodal
rotary drum molded by a foamed polystyrene material or the like having an acoustic baffle effect
and the like, and 11 is a cylinder mounted on one side of the substantially cylindrical rotary
drum IO. One force, 12 is a balancer for making balance with the above-mentioned speaker 11
which is engaged with C (7 · speaker 11 and bites to the side of 4 cylindrical rotating drum 10
(outside in j: xll)) It is.
The reference numeral 13 is a motor in which one of the substantially circular node-like 711
rolling drums 10 is placed at the center arrow by a frame 17.18 or the like via a '2 temporary 14'
C rubber bung 15.16, 19 is its stator, 20 is It is a rotor and is a so-called outer rotor type motor.
The motor 13 is provided with a frame 22 at an upper portion of a rotor 20 via a rubber bushing
21 (4), and is supported by the frame 22-at substantially the center of the substantially
cylindrical rotary drum 10. As a means for attaching the above speaker 11, balancer 12 and
frame 22 to the substantially cylindrical crucible rotary drum 10, the material of the rotary drum,
that is, for example, due to the nature of polystyrene foam, etc. 25 is attached to a sandwich
shape and a bag so that it can be held in a stable state by using the above-mentioned expanded
polystyrene foam and can be sufficiently held against the weight of the speaker 11 and the
balancer 12 . Reference numerals 26 and 27 are audio signal input terminals, which are
connected to the brassinos 28 and 29 provided on the stator 19 of the motor 13. The brassinos
28 and 29 are in constant contact with the conductive ring 30.31 provided on the rotor 20. The
voice signal from the voice signal human power terminal 26.27 is conducted to this, and the
speaker 30.31 and the input terminal 14 of the speaker 11 are connected to the speaker 32. 11
to feed and drive. Since this device is structured as described above, when the speaker 11 is
driven and the substantially cylindrical rotary drum 10 is rotated by the motor 13, the
substantially same node-like rotary transfer drum 10 is Since the balancer 12 provided opposite
to the speaker 11 is balanced and balanced, it has a roughly lll cylinder and a flat outer shape, so
that the air resistance is also small. The noise is eliminated, and the speaker 11 is mounted
within the above-mentioned substantially same fm flat rotary drum 10, so the noise of the cone
paper [11 after = = i is collected and the phase interference is generated. Furthermore, since the
substantially cylindrical rotating drum lO is light in weight and has an acoustic baffle effect such
as expanded polystyrene and the like, and is lj × -rounded, it is a tremolo, a four-piece rotating
system for winding Reduce the moment of And tremolo effects that are sufficiently related to one
another. Figure 4: Four sheep, z1 ming 61 n "· jl woman) shows an example of a conventional
