In order to reduce differential distortion and vibration at the time of large electric power input, it
is used as a skin speaker. The conventional speaker is configured as shown in sll. That is, the
frame 6 ′ ′ i 12 − · −t M is fitted to the area decoration 6 made by the center pole 1 by the
bed plate 2, the ring magne, the ring 3 and the ring 4, and the periphery of the frame 60 Fix the

hole coil bobbin 10 to the central part of this diaphragm 8-and the middle part t frame 6 of the
coil bobbin 10- Even if the speaker is held by the damper 11 fixed to 11 and the dust cap 12 is
attached to the top of the coil bobbin 10 by the MR, the speaker has an equivalent Q of 1 for
example. If the maximum resonance frequency IRfo is the maximum tI 鴨, 126B7., And so on, and
the low resonance JiI 披 @ 1o) decreases in high frequency. What is the lowest frequency 16? As
shown by the peak of Fi and Jl and # f3 の, the output of io is generated in the sound pressure

above-mentioned conventional O defects. Hereafter, we will make a visit to the home town by one

center ball in a roving yoke so that it can be a solitary circular magnet. A frame A18 is coupled to
the field a 818, and a diaphragm 19 and a diaphragm 200 peripheral edge are attached to the
frame 1801 鎧 along with the surface of a brass crush agent. Further, a coil povin 22 provided
with a poisfill 21Vt is connected to the lower part and the outer part of the central part of the
peristaltic fistula 2Q. In addition, a permanent magnet & 28 is attached to the inner ring i1 of the
coil povin 22 and the outer middle corridor is held by a length damper 24 wearing a frame 18
such as a frame 18 of a frame @noodle. In addition, the above-mentioned permanent magnet
plate 23CI) penetrates through the through hole 26 at the center to form a center pole 1410. , II:

27 are polarized so as to be S reefs. A dust cap 28 is attached to the upper surface of the central
portion of the vibrating rod 20. By this configuration, when the speaker is operated, the attached
permanent magnet cage 23 is also oscillated with the voice coil 21 attached to the coil bobbin
22. However, at large & temporarily, a of the opposing ball heat 14 or permanent magnet plate

22, the number of impellers can be increased, and the sound crushability can be affected by a
shadow #, but the permanent magnet plate 28 is relatively glossy If you use Manganese J & Mi
