[Detailed description of the invention] This 4 books, lit Libono 4u speaker! The invention relates
to a vibrator such as LL Lori / Thois coil field vibrator. 7'11: /) 1 + (Scoulder-type board) is a side

both paid out by flowing. For this reason, the insulating plate must be very full & in the case of
such an insulating plate, the heat capacity is small δ, and the number of electricity to the Heus
coil (': Rises, and (I don't strike + or something like this will occur between the diaphragm or
temporary strain). Therefore, S-promoted rice forms a plate on one side with a heat-resistant
resin of a polyimide resin without being appelled as a soda, and also has a highly heat-resistant
cherry glaze phase. So, my father used to pay money to collect and hold a conductor for a long
history. However, this type of physical swimming can not cope with the use of large input and
negative time because it can not be sufficiently dealt with. 4!。 +2 As shown in FIG. 1, this heat
is located near the center of the air gap of the peristalsis temporary 1 distributed in the magnetic
air gap G of the magnetic circuit, so that the magnetic pole 1 has good heat conductivity such as
heat dissipation The failure is located in the central part of this gap, because the temperature of
the t-b portion rises to a non- "toy" as indicated by the warm-air distribution curve T 詠 T than a
certain peripheral part. Irrigate from there. In addition, 2 is a magnet, 3 is a ball yoke, and 41
loop. The main body is made of the above-mentioned point, and its purpose is to provide a
vibrating water with a length of 1 for the purpose of high input and long time flight. Will I

celebrate 11u in F444 with reference to Figures 42 and 3? The same reference numeral 1S is
attached to the same member as the key. FIG. 2 shows a half of the printed voice coil type
diaphragm 1 according to the present invention, and the portion jm with diagonal lines is four,
and the letter C with a mark of 7J-smoothly spirals nine voices The coil is disposed in the
magnetic space 1III of the magnetic circuit, or the position of the voice coil C which is placed in
the middle of the taste gap is 1-1- of the voice coil C's head 1 & 1 becomes larger than 1 There is.
俸 · 斜 · 縁 · 1 not hb minutes 1b of the diagonal edge of the same 24 1 1 7 j (シ の 下 杷 杷 edge
plate under the temple small 11). As mentioned above, it is smaller than the small-cell side pond
of the air resistance i'1llSI + 1- where the width of the 晦 悴 11 L is large and large-(, the value of
the non-heat heat or less than the side of the side d) Such as the third factor, the anastomosis in
which the temperature distribution of the 蜘 & N soil over the magnetic 仝 -G is T で 不- As can
be seen from the graph, when the input power to the sneaker is a single turf, its beak Wl drops as
shown by ΔT when compared with the conventional temperature distribution data MT shown by
break 1. Well, conversely, when the peak of the distribution temperature is set to 1 1 j, the
allowable input power increases.
In other words, 11 people or more of the speaker. In the case of the above-mentioned
cancellation 11, the voice coil C is flinted to a yen-free penalty or 9) other than the cancellation
9. It may be 7 linoto V such as L oval. In this study, we made a series: U, U, and B, the width of
the conductor that forms the Heuss coil is made larger at the central part of the magnetic W
series l), vibration & heat on the surface Eleven minutes are turned into ten buttons, and the
temperature at the station ib decreases little, and when it comes to adulthood and narrowness
IIIJ 1 The current density of the voice coil in the peripheral part where the conductor width is
small becomes dogier and is effective for increasing the f conversion effect as a speaker, and it is
a compact and large allowable input required for the H1 Fi tweeter An optimal diaphragm can be
obtained.
