DETAILED DESCRIPTION OF THE INVENTION The main body IN is a horn speaker 1cWIA that is
efficient, excellent in characteristics and stable. As a conventional horn speaker, l, l ? # l l l l l l l

?? ?? ?? ?? ?? ?? ??. Moreover, as the horn, the opening has a llll 1 m shape and
1)), and there is no directivity 11 due to the use of the dome wet-working plate, and the O tube
pressure on the central axis of the speaker is weak. To the other S + tube pressure and Okaba
degree, eh. In general, Suvy * is because it is an effective means to increase the efficiency of the
speaker by increasing the sound pressure on the central axis. The present invention provides a
highly efficient horn speaker by eliminating the problems inherent in lIl and beyond. Hereinafter,
to explain the present invention according to one embodiment e @@@. Column-shaped casting in
the center of 1 # i! [Dane, To 2 set up, it's a circle II-like brow], and this field-E1 and Madane,
because to form the field part by To 2 That is, the upper lIK butterfly padbacking arrangement of
the roof 1 is arranged, the scrap edge of the dome-shaped sliding plate 6 is arranged on the
backing 4, and the ls coil 6 is suspended on the dome-shaped sliding plate 6. In the case of an air
filter, it is configured to be located in the air gap, which is constituted by a field air gap, that is,
an air gap 1 and an air gap, toe 2. And, on top of these, the W is straight in the shape of a
truncated cone 1 Ssa иииииииииииииииииииииииииииииииииииииии 1) A gold cap 1111 is cleansed in a book, and 3) This
stable 1 111 has a length that is almost covered with the caustic dumpling movement. Both the
metal shell 11 and the shell 1 can be coated with 1111 KII and applied, and the fitting between
the both can be provided with a shell MH convex for axial mounting. Serious, fitted wIi11 good */ 10 A. It may be molded with 1.8 resin, and may be constituted by Al-Ken Dai-Camet. Federal 1
dome-shaped vibration 1 [60 peripheral portion may be pressed at the lower end portion of the
horn 10, or may be fixed to the backing 4 together with the backing 4 by using an adhesive. The
relationship with the O sound pressure on the central axis of the speaker to be awarded to the
opening angle of the opening IN + of 'tk ?, Ho y 1 o is * Jl, because 10 jF to 3 o degrees is the
best as shown in the 811 c.
As mentioned above, the horn speaker of this invention equips a field part with a poise coil,
arranges a good dome ** moving board, @ 01li is linear on the above-mentioned nose 1ini and is
outward Ell. Because the horn with the opening can be connected, the bandage emitted from the
dome-shaped vibration i + ui is emitted at the opening of the horn-and the central axis pc1m2 of
the speaker, and the) center of the four speakers- The sound pressure at the top is eclipsed, and
the efficiency as a speaker can be widely praised, and it is a thing of great value for laughing. 4,
