Abstract

PURPOSE:To obtain a complete nondirectional characteristic with an additional installation of a simple member by providing a reflector in the vicinity of opening of a horn speaker set in the vertical direction. CONSTITUTION:A horn speaker 1 is set in the vertical direction, and a reflector 3 is installed in the vicinity of an opening 2. The reflector 3 is fixed to the horn speaker 1 by a support bar 5 so that a sound 4 outputted from the horn speaker 1 can be transmitted parabolically and uniformly in the horizontal direction. In this way, a complete nondirectional characteristic can be obtained only by adding a simple member.

構成されている。Conventionally, in this type of speaker system ζ2, for example, as shown in FIG. The overall directional characteristics of this system were not uniform, that is, they contained distortion, as shown in Figure 2. It is obvious that increasing the number of devices would gradually reduce this distortion, but this was not possible due to the installation space, and such a combination would only increase costs. The purpose of the present invention is to eliminate the above-mentioned drawbacks and provide a speaker system that can obtain completely omnidirectional characteristics. 1;
