DETAILED DESCRIPTION OF THE INVENTION The present invention is intended to be used
outdoors, to prevent rainwater from entering the driver unit when it is raining, and to provide a
horn speaker with a high degree of safety. In general, a horn speaker is configured as shown in
FIG. That is, through the edge fixing ring 7 on the magnetic circuit 6 constituted by the plate 3
provided with the center pole 2 having the through hole 1 at the center, the ring-shaped magnet
24 and the ring-shaped upper plate 5 as well. A dome-shaped diaphragm 8 is attached, a voice
coil 9 fitted to the magnetic gap of the magnetic circuit 6 is coupled to the diaphragm 8, and a
cover 10 is covered to cover the outer surface of the diaphragm 8 An equalizer 11 with an end
face dome shape is attached to the back surface of 8 to form a driver unit 12, and a horn 13 is
attached to the bottom of the magnetic path 6 of the driver unit 12. When using such a horn
speaker as a unit such as a monitor speaker of the stay 2 outdoors, it is necessary to direct the
opening of the horn 13 in the direction of the performer, so the driver in the cabinet 14 as
shown in FIG. The unit 12 is attached downward with the opening of the horn 13 directed
upward. In such a configuration, while playing, it is raining and 1 '降雨': to * @, m x x x-713 °, □
x Q "CF; intrudes into the '4' bar unit 12 to There was a fault that it was destroyed and 3
performances became impossible. The present invention eliminates the above-mentioned
drawbacks. Hereinafter, an embodiment of the present invention will be described with reference
to FIG. 3 and FIG. The entire configuration of the horn speaker is the same as that shown in FIG.
1, and here, the horn as a feature of the present invention will be described. FIG. 3 is a crosssectional view of a plane when viewed from above the horn 13, and FIG. 4 is a cross-sectional
view of a side surface of the horn 13. In the middle of the side walls 17.18 from the throat
portion 15 to the opening portion 16 of the horn 13 and the upper and lower walls 19 and 20,
an inwardly projecting protrusion 21 is provided to prevent rainwater from entering the throat
portion 15 of the horn 13. A drainage hole 22 is provided in the middle of the V-shaped
protrusion 21 of the lower wall 2o, and a drainage pipe 23 is connected to the drainage hole 22.
Since the horn 13 is generally manufactured 4 by a method such as molding, die casting, casting
or the like using a synthetic resin or metal, it is easy to provide the ridges 21 on the inner wall.
As described above, since the horn speaker of the present invention is constructed, as shown in
FIG. 2, even if there is rain during the use as an outdoor stage and installed as an outdoor stage,
rainwater is collected by the ridges of the hole It is possible to drain the water from the drainage
hole to the outside, so it will not break into the driver unit and destroy the vibration system parts,
and the performance in the rain may be interrupted, which is extremely reliable. It is a great
thing of practical value.
