DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flat diaphragm
type speaker unit [1, more particularly, to a speaker unit having a coaxial flat diaphragm
mounted above it. The flat diaphragm has a relatively flat sound pressure physical property over
the whole range of horsepower, and it can be 0 and so on 41 to enjoy the reproduced sound by
the sound * 6ml SIml 1ml, it has come to be provided with the Sbika system system. In the case
of a speaker system with a flat diaphragm, the movement of the speaker system by Kfi is very
small. If it is arranged coaxially, the image of the ttyy7 layer itself is used. However, in the case of
the coaxial type using a flat board, it was difficult to pull in and pull out the driver unit in the
center, in detail, to feed the voice coil. In the coaxial type unit conventionally known, in the
center unit having a tweeter, a hole is formed in the b plate constituting the magnetic circuit, and
a feeder of this busy tweeter is made, and further, a yoke is provided. : ? through the hole busy
feed line, voice coil KIi! It is a connected file FILE. In this case, since the feed line passes through
the magnetic mouth path, the insertion operation must be carried out in a hand-chamfered state,
which is very difficult, and further busy processing costs by drilling holes in the plate or yoke.
One; had problems increasing. Therefore, this invention is intended to provide a feeder that is
easy to pull in and out of the feeder, and the feeder to be the inner voice coil bobbin is pulled in
through the slit or the hole of the outer voice coil bobbin. It is time to make the configuration.
The details of this invention will be described along with the attached drawings during leisure
time. The figure shows the super-high-pitched part, the high-pitched part and the driver unit part
of the speaker unit which is coaxial type and configured using a plane diaphragm, the symbol /

the voice coil V is wound around this voice coil bobbin JIJ [- j # ? # ? ? / 4 LK close fK window
hole is pierced, medium IIII terminal l э э / If /-S is extended t14.
The relay terminal of the frame system-KiIf2 is created. The window hole J bored in the whiskey
coil hovin 3 is square. ': It may be a circular shape, a 17-point shape, or the like, so that the
movement of the voice coil bobbin is not interfered. The lead @t S is disposed along a straight
line connecting the end portion 3 m of the voice coil 13 with reference to the middle @ II child
and extended to the relay terminal j. The flat diaphragm type speaker unit of this invention. Since
the configuration is as described above, the voice-fill bobbin JJ [the feed line + 1-do @ 15 is
extended through the pierced window hole to the required part outside, and the voice-fill bobbin
does not have ii @ L. As a result, a window hole is bored in a component of the magnetic circuit,
which saves time and effort for this 1 (17-wire). In one or more of the explanations, an example
was shown in which the feeding of the driver unit of the Stuttering Group diaphragm was drawn
in through the chamber hole of the voice coil that constitutes the driver unit of the outer hightone diaphragm, ? X, vibration The driver unit of the board can also be applied to the case of
using the window hole of the voice coil bobbin of the driver unit of the mid-tone part and the
low-pitch part. As apparent from the above description, the flat needle of this invention-4-!

the center using window holes drilled in the voice coil bobbin located on the outer periphery (I) It
is easy, and there is no need for the operation of drilling the magnetic circuit groove 1ffl
evaluation material busy hole.
