DESCRIPTION JPS5772695
BRIEF DESCRIPTION OF THE DRAWINGS FIGS. 1 and 2 are a plan view and a longitudinal
sectional view of a conventional speaker, and FIGS. 3 and 4 are a plan view and a longitudinal
sectional view showing one embodiment of the speaker according to the present invention. FIG. 1

DETAILED DESCRIPTION OF THE INVENTION This invention relates to the improvement of a
single speaker frame. Heretofore, there have been shown such speakers as shown in FIGS. 1 and
2. In the figure, +11 [frame, (2) is an edge, (31 is a diaphragm, 14) a dust cap, (5) is a magnetic
circuit, (6) is an input terminal, and (7) is a lead wire. Next, the operation of the conventional one
shown in FIG. 1 and FIG. 2 will be described. The input signal applied to the input terminal (6) of
the speaker is independent of the positive terminal and the negative terminal from the input
terminal insulated from the frame and il + isolated from each other. + 71'e transmission is added
to the voice coil. The voice coil installed in the magnetic field vibrates according to the input
signal, and at the same time the diaphragm also vibrates, and the conventional input terminal,
which is emitted as sound in the air, is insulated from the frame when it is attached to the frame
Needs a complicated structure, needs to attach a dedicated input terminal, etc., and is expensive
and expensive. ~ This solution eliminates the conventional drawbacks as described above. It is an
object of the present invention to provide an inexpensive speaker assembly which can be
manufactured with an intermediate structure by using a yc conductive frame divided as one and
made of yc conductive frames as an input terminal. An embodiment of the present invention will
be described below with reference to FIGS. 3 and 4. 3 and 4 are front and longitudinal sectional
views showing an embodiment of the speaker according to the present invention; 1; a plurality, in
this case four, in combination (2) to form a speaker frame A frame part of A, +2) is an edge, (3) is
a diaphragm, 14) is a dust cap, (5) is a magnetic circuit, (6) is an input quadruple, (7) is a lead

wire, (8) ) Is a voice coil, that is, the present invention divides the speaker frame into two or more
on its circumference, or four in the above embodiment, and the frame portion which is isolated
from the plate and each frame lal. 11bl, (lcl, (formed by id, (lal, (IC) is used as one child, frame
portion flat, (lcl '-f input signal applied to an input signal 1a) Plus, (If minus lcl, frame part made
of Jt = separate material insulated from the input terminal and made of independent material (lal
* (lcli, transmitted to the conductor and added to the voice coil) The guide wire and the input
terminal may be any part of the frame portion 11a), (lci), and the attachment of the guide wire
and the input terminal may be at different positions.
In addition, a dedicated input terminal is not required, and in one case (3), it can be easily
attached to any place by means of a screw and the like, and the flexibility of the location of the
input terminal can be greatly expanded. According to the present invention, according to the
present invention, since the frame divided into one is used as the input terminal, the mounting of
the input terminal and the lead wire with the frame can be simply installed at any place, and the
flexibility of the place is greatly increased. There is an effect that can be expanded and made
inexpensive.
