The electric am electroacoustic transducer used as an alarm generator such as Ara-1 watch has

permanator with a distribution tower on the plate 2 so as to sandwich the excitation coil 4
written on the center pole S, which is mechanically and magnetically condensed, and the center
pole 3 The nose stone 5 and the rim 1 & 1 111 are constructed, and this 0jlJll # 1 is a plate at
the lower end of the cylindrical support 6 made of non-dwarf material such as a yellow pot! The
Oj 1 is fixed and housed in the support 6. The upper surface of the support 6 was scratched from
the metal plate of jlliKa ready-@ 7 t) 9 sides were simply supported and t. The diaphragm 7 is
made of a material having a lightness as thin as S-bonded. A predetermined distance Ka is formed
between the vibration (2) and the vibration (1) (7). Since the conventional 01EII stationary
electroacoustic transducer having such a structure uses the ring-shaped permanent magnet 5,
the processability is poor, and the number obtained from the material block is small because of
the round IIO, and the se structure is the image side And, there is a disadvantage that the
production cost is high. Therefore, the present invention provides a simple and easy-to-make
11KII electric-electro-acoustic transducer at a conventional permanent magnet, and according to
the embodiment shown below S Jllvt theory-I will.
4Sillll, JI 411 ? S and ? 6 show an example of the present invention KIE iam electric electroacoustic transducer O. First, ? 3am and 1II 4- Is it ail ? ?? & ?, encouragement part 9 is pure
iron * Oa1! One circular plate 10 made of one material and one at the center of the plate 10, the i
is a mechanically and airy condensed center ball 11 and a center pole 11! It comprises a set of
llN1 coil 12 and three magnet pieces 136 ░ 13 &, 15e spaced on the plate 2 with the center ball
114 in the center. The excitation IS 9 is accommodated in a cylindrical support 14 made of
nonmagnetic material, and the periphery of the plate 100 is fixed to the lower end of the support
140. At the upper end of the support 14, the periphery of the inking plate 150 made of flexible
gold 11 was simply supported, and it was t. The thin film I [16 made of a magnetic material
which receives the magnetic action from the excitation unit 9 is connected to the lifting rod 15.
Such a configuration [Electric device electro-acoustic transducer according to the proposed home
plan, is excited by the electric light change in the exciting coil 12 fj W? The magnetic car iIAgl
generated from it and thereby vibrates the diaphragm IS $ via the thin plate 16 '. One that
generates sound and is similar to the conventional one in one action. However, the permanent
magnet t1 disposed on the plate 10 looks plexus in the conventional ring shape. 5IIIII) Since arit
is divided by 7t11 stone fragments 13g and 156.13g, and the conventional ring shape is also OK,
the processing is 11III # and the material from the material pack (2) without waste Large 1kK
can be taken out and can be built Ell. ????????????? iio practice 111a 12 pieces of
magnet 13 m, 1! In the example shown in FIG. 1143 and FIG. 14 and the same number as m-, the
operation is also the above-mentioned 0-9. As described above, in the case of the magnet piece 2, they should be arranged concentrically at an angle of 180 "each at the center of the center pole
11 at the center pole, and at intervals of 120 ░ each in the case of the magnet piece 5 ? O.
According to the js * wh ? 15 KJi 1 combined shade 441j 11 C-et al. As mentioned above,
although it scolded about the charge of the main body music, it is not a thing that two pieces of

ISa, ISi, and 13mk inner square MtL are arranged in one circle and formed into an arc that is
joined at a certain rate. May be a tatami mat, not the% O that is added to the figure O ? ? ?,
but various O qualities l! Or t can be improved.
(1) As described above, the electric aIIN electroacoustic conversion i1m according to the present
invention is changed to the permanent magnet ta ? OIJ ring-like O1 so that a plurality of magnet
pieces are made circular on the plate centering on the center pole. Since the structure is
appropriately arranged, it is easy to make am processing, and it is possible to take out large jIK
from the material block, and it is possible to make 11KII and to make a shell, etc. There are
things that can achieve the purpose of the period and have practical effects.
