DESCRIPTION JPS55130495
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a right half vertical sectional view showing one
embodiment of the present invention, and FIG. 2 is a partial perspective view showing an
assembly of a voice coil and a tape. In the drawings, the same reference numerals indicate the
same parts, 1 is a lower plate, 2 is an upper plate, 3 is a magnet 4, 4 is a yoke, 5 is an outer
frame, 6 is an inner frame, 8 is a voice coil, 9 is a bobbin, 10 Is a spider, 12 is a diaphragm, 13 is
an outer peripheral edge, 14 is an inner peripheral edge, 15 is a lead wire, and 16 is a tape.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure in
which a flat plate speaker using a circular flat plate-like diaphragm sound is darkened, and in
particular, a diaphragm and a bobbin of a Heuss coil are locally attached. A flat plate speaker
with a diaphragm in the form of a flat plate is narrower in piston vibration habituation area Fi
than a cone type speaker, but since the vibration machine is a flat plate There is an advantage
that (1) town F, t pa. 7) of; i'-r can be obtained which has a flat tip and a flat phase-wave number
characteristic. In addition, the cone-shaped speaker is improved by using a honeycomb structure
that can increase the thickness and the thickness as well as a problem that the piston oscillation
region is narrow, as a coupling, or a material having a large Young's modulus can be obtained.
Have you been able to do the same thing, recently highlighted? It has come to bath. However, as
the bobbin is used for the purpose of hatching, because the thin material is used, the contact th +
wrinkle with the diaphragm can not be taken sufficiently, and it is only one rod to carry out bI
attachment between the bobbin and the diaphragm. there were. This device is a device not seen
in the above point 9 and uses a tape in order to completely carry out the inherent gold of the
bobbin and the diaphragm. Shown below 冥 7i! We will explain the details of this invention
according to one example. That is, in FIG. 1, +1 1 is a hollow disk-shaped lower plate (21 is a

paper tape α6 is shown in a second frame. As described above, in the case of the flat-panel
speaker vc, the hoblin (9 (and the finger movement q2 and so on) uses a t-tape to increase the
number of blood spots. That is, on the inner peripheral wall of -thI ヲ hovin +9+ of the paper tape
0e, the end of the set tape u61 is stuck to the upper end of the hovin (9) as the upper end of the
hovin (9). This tape U & and the bobbin (91 and the upper 9 * [in the diaphragm 1121vc close to

transmitted completely to the vibrating plate. Moreover, the diaphragm plate and the bobbin

91 can be more easily fixed). As mentioned above, these 4 plans are planer-shaped brows! Since
the tape is attached to the solid layer between the plate and the bobbin, and the contact surface
between the bobbin and the diaphragm Kamakurajima is put on, the solid layer is made into the
original metal and the voice coil drive is completely convex. I can tell temporarily and also 1i of
the diaphragm and the bobbin! i) The formability at the time of layering is also improved. 4
