BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the present invention,
FIG. 1 is a perspective view, FIG. 2 is a partial side view thereof, and FIG. 3 is a cross-sectional
view showing a sound path of a unit adapter. 1 иииииииии Speaker horn, 2 иии i и branch horn, 3 E ииии

The present invention relates to a horn speaker in which a large number of drive units are
combined together into one horn so that high output can be obtained, and a purpose thereof is a
branch horn branched from the horn Furthermore, the sound path of the unit adapter is inclined
about 30 degrees so that rainwater etc. does not intrude into the unit adapter at the tip, and the
phase difference of the acoustic output of each drive and part is not large orange Providing a
horn speaker that equalizes the sound path of the unit adapter leading to the part (C).
Hereinafter, the details of the present invention will be described with reference to the drawings
showing the embodiments. [2] A split horn fixed to the throat of a double speaker horn and a
double horn 1. In the drawing, it is branched into two parts. Reference numeral 3 denotes a firstdrive unit adapter fixed to each branch horn 2, which branches into three sound paths 4, and a
drive unit 5 is identified at each tip thereof. The length of each sound path 4 is designed to be
equal, and is inclined about 30 degrees with respect to the horizontal direction. Therefore, in this
example, all the 24 control parts gather in the throat of the horn in the same sound path, the
phase difference of the sound output is small, and the intrusion of rainwater is also prevented by
the inclination of 30 degrees. As described above, it is a horn speaker that can obtain high
output, and exerts a great effect depending on the application. If an electrical insulator is
intervened when attaching each unit adapter, the failure is less and the power is excellent as a
multi type horn speaker. The
