DESCRIPTION JPS5723399
1t и и Specification 1, title of the invention

3. Detailed Description of the Invention The present invention relates to a speaker equipped with
a mechanical filter, and it is an object of the present invention to reduce the number of low links
of a diaphragm and a voice coil bobbin and to reduce gear knob rubbing of the voice coil.
Hereinafter, an embodiment of the present invention will be described with reference to the
drawings. In the figure, 1 is a center pole, 2 is a macnet, 3 is a plate, 4 is a voice coil 2-"bin, 5 is a
voice coil, 6 frame, 7 is a first damper for connecting the bobbin 4 and the frame 6, 8 is an
adapter attached to the upper end of the bobbin 4, 9 is a flat diaphragm, 1o is a coupler
integrally provided on the lower surface of the diaphragm 9, 11 is a step 1olL provided
substantially at the center of the coupler 1o An edge (elastic body) that operates as a mechanical
filter that combines 7 with the adapter 8 of the bobbin 4 and prevents regeneration of a signal of
a predetermined frequency or more, 10b is the lower end of the coupler 1o to the field portion
further from the step portion 101 A protruding portion 12 is a second damper which connects
the lower end of the protruding portion 10b to the frame 6, and an edge 13 which connects the
diaphragm 9 and the frame 6. In the above configuration, in order to reduce the rolling of the
diaphragm 9, it is sufficient to lengthen the arm of the moment. That is, the longer the distance Y
from the diaphragm 9 to the second damper 124 shown in the drawing, the better, and the same
applies to the low link of the voice coil bobbin 4 (the longer the arm of the moment, the better.
The distance Z from the adapter 8 to the first tamper 7 is EndPage: 1: So, as in this embodiment,
the coupler 10 is provided with the projection 10b, and between the edge (elastic body) 11 and
the second damper 12 If the distance X is made sufficiently long, both Y and Z can be made long,
whereby the rolling of the diaphragm 9 and the bobbin 4 can be reduced and the gap and friction

can be reduced. As described above, according to the present invention, a part of the coupler
integrally provided on the diaphragm is coupled to the voice coil bobbin via the elastic body
serving as a mechanical filter, and one end of the coupler is more field than the coupling portion
of the elastic body. Since it is made to project toward the part and the damper is joined here to
couple the coupler and the frame, the distance between the elastic body and the damper can be
made long enough, as a result of which vibration Since the length of the arm of the plate and the
voice coil bobbin can be made sufficiently long, the rolling of the diaphragm and the voice coil
bobbin can be suppressed as much as possible, and the gap and friction can be reduced.
