DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic
orcan, wherein the tremolo effect can be clearly heard by reproducing a tremolo modulated
belief with a speaker having a horn. In the conventional electronic bibino type, as shown in FIG.
1, the speakers 2.3 are attached to the front face 1a and the O1 l + face 1b of the cabinet 1
constituting the organ body, and these loudspeakers 2.3 The tremolo modulated signal is
reproduced from. This is because the tremolo effect is an end effect with a period change of the
sound volume and a fluctuation of the phase, 10 · 1: 2 / y ′ ′, J− ′ ′ 2 as shown in FIG. If
the speakers 2 and 3 distributed to 90 degrees are used, it is possible to hear a sound
accompanied by a change in the phase length and the on gate. However, since the conventional
speakers 2 and 3 are used in such a conventional electronic organ, the directivity of each of the
speakers 2 and 30 is not so sharp as shown by D in FIG. There is a problem that the sounds from
3 and 3 mix in an obscure manner and the tremolo effect is not sufficiently exerted. . The present
invention provides an electronic organ that solves such conventional problems. That is, in the
present invention, as shown in FIG. : A speaker 6.7 having a horn 4.5 is attached to the side
surface 1b. Note that the horns 4 and 5 do not have the power. It may be integrally provided C)
or may be provided separately from the speaker 6.7. When such a horn-type speaker is used, its
directivity is sharpened to the ratio D compared to the conventional one as shown by D in FIG.
The temporal change of the volume and the fluctuation of the phase can be heard more clearly,
and the tremolo effect can be further expanded.
