DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for
improving the safety of a horn speaker. As shown in FIG. 1.2, the conventional horn-type speaker
is a driver unit comprising a front plate 1, a rear frame 2, a magnet 3, a voice coil 4, a diaphragm
5 and an equalizer 6 integrally formed on the front plate 1. The horn 9 is fixed to the front plate
1 by a screw 10 and attached to the front surface of the sound emitting portion 8 of FIG. The
smell is that, in such a conventional device, the conductive object 11 like a thin pin is 7 or r! ;)
I'2-When pushed from the horn 9, the tip thereof enters the driver unit T from the gap formed in
the portion of the equalizer 6, breaks the diaphragm 6, and contacts the voice coil 4 There is a
problem in safety that there is a risk of causing an electric shock accident. Therefore, the present
invention is intended to solve such a problem and to provide a safe horn-shaped force, an
example of which is shown and described in FIG. 3.4. The same reference numerals as in FIG. 1.2
denote the same parts as in the prior art. This speaker is characterized in that the fine and strong
net 12 is held by the driver unit 7 and the horn 9 so as to cover the entire front surface of the
sound emitting portion 8 of the driver unit 7 and attached. The net 12 may be made of a strong
cloth known as a sala / net, in which case the net 12 is first suspended by the pin 13 or the like
on the front of the sound emitting portion 8 of the driver unit 7. Attach the rear end of the horn
9 to the end of the horn 9 and screw it, o * of [i! 115i 2 f BL 511 Cf, L, ble% 11 C,! :%) Can be
installed well without 3 Further, as the net 12, metal such as metal mesh or synthetic resin may
be used, and in this case, it may be pressed or formed into a predetermined shape in advance.

Thus, in the horn-type speaker of the present invention, the front of the sound emitting portion
of the driver unit is covered with a fine net, so even if something like a pin is inserted by a child's
mischief etc. It is possible to obtain a safe speaker without the possibility of contact with the
voice coil of both parts. In addition, since the net is held between the driver unit and the horn,
the mounting is simple and inexpensive, and the sound quality is not adversely affected.
