TECHNICAL FIELD The present invention relates to a speaker system C and, more particularly, to
a speaker system for broadcasting (for public relations) used in municipal disaster prevention
administration recklessness and the like. [Prior Art] Conventionally, in a loudspeaker system of
this kind, for example, as shown in FIG. 1 == FIG. 1 =, a plurality of horn loudspeakers 1 (four in
the figure) are shown. The overall directivity characteristic of this system, which was a system
arranged as described above, is not as uniform as shown in FIG. If the number of horn speakers
used is increased, this distortion will gradually be reduced (it is obvious from the point of
installation space that it is impossible, and such a combination only leads to an increase in cost)
[Objective] The purpose of the present invention is to eliminate the above-mentioned drawbacks
and to provide a speaker system capable of obtaining perfect non-directional characteristics.
[Configuration] The present invention is to achieve the above object. τ 2, vertical direction 1; set
horn speaker, and sound from the horn speaker in the horizontal direction C mean -C; to reflect
1: v! , And a reflector mounted near the opening 6 of the horn speaker, and is configured to be
combined with a second mounting post. Embodiments of the present invention will be described
below with reference to the drawings. 6 and 4 are respectively a block diagram of an
embodiment of the present invention and a directional characteristic diagram thereof. In FIG. 3
(b), the horn speaker 1 is set in the vertical direction C =, and its opening 2 (: a reflector (for
example, made of aluminum) 3 in proximity is output from the horn speaker 1 The voice 4 is
fixed in the horizontal direction (2-radial C 2 and uniform [2 to be delivered 2 by the support
rods 5 by two horn speakers 1 C. Fig. 3 (as apparent from the configuration shown in Fig. 2 (: its
directivity characteristics are completely non-directional (Fig. 4) · further C; such a speaker
system as shown in Fig. 5) The installation work can be simplified by combining it with the two
mounting columns C. @ [Effects of the Invention] As described above, the present invention
provides perfect non-directional characteristics only by adding simple members. Can be obtained,
and distortion can be reduced. In addition, the installation work can be simplified by combining
with the mounting post.
Brief description of the drawings
1 and 2 show a block diagram of a conventional speaker system and its directivity characteristic
diagram, and FIGS. 3 and 4 show a configuration diagram and a directivity characteristic diagram
of an embodiment of the present invention, respectively. FIG. 5 is a block diagram when the
system according to the invention C2 is combined with the mounting post.
