[Detailed description of the invention] ■,-1-H :: L · olfactory) ': to 6 6', 井 考 案 This invention
relates to a speaker edge, in particular to a speaker edge in a speaker having a rectangular flat
moving plate. In recent years, flat diaphragms have attracted attention due to the peristaltic
effect as a moving plate for speakers, and in particular, there are many diaphragms of old cedar.
FIG. 1 is a cross-sectional view showing the structure of a speaker and a speaker edge of a
conventional speaker having a rfji motion &. The rectangular image 11111 is an elastic body and
is stretched over the supporting portion 3 via the edge member 2. In the speaker having such a
configuration, when the diaphragm 1 performs the latitudinal movement, the relationship
between the force applied to the edge member and the displacement of the edge member itself
becomes non-linear. It tended to be non-shaped. The object of the present invention is to provide
a speaker edge in which the relationship between the force applied to the speaker edge and the
displacement of the speaker edge itself is linear in the case where the shooting plate is operated
at large @ @. It is in. In the stand-by mode of the present invention, a 72-illuminous edge member
is attached to the valley side of the rectangular imaging plate, and a rotational axis for winding
the ridge of the nuclear edge member is provided correspondingly to the nuclear edge member.
A tension applying means is provided on the above-mentioned moving shaft so as to move a
constant tension on the # 1 original edge member. An embodiment 11 of the present invention is
shown in FIGS. 2 and 3. A film-shaped edge member 11 is attached to each side of the diaphragm
10, and the edge member 11 has an end-to-end feeling of @@@ 12. The solid layer is wound
around the tol moving shaft several times. Further, it is pivotally supported by a bearing 14 fixed
to the pivoting @ 12d frame 13, and the shoulders of the @ 120 shoulders are moved to the
outside of each side of the reinforcing plate 10 by a constant tension T so as to move on the
curve frame 13. It is supported via a spiral spring 15. A portion of the nuclear spiral spring 15 is
shielded from the outside by a housing 16 and the housing 16 is filled with a credible liquid b for
Q damping. Ceramics, in the present invention, if it is a 7 m & 10 rj rectangle, it is not a plane
which is a plane, but may be a curved surface. When the diaphragm 10 enters @ @ with a
speaker edge consisting of a striking configuration of 1-3-5 1 or more, the edge of the diaphragm
lO is accompanied by one lower @ of the diaphragm lO, and the edge is always normal! When a
force of 1 or more tension applied to the ItI material 11 is opposite to the tension T and the
cedar edge member 11 vc / Il is in the opposite direction, the above! (2) a 嘲 12 resists the power
T] @ L, because the edge member 11 is drawn out, the force acting on the edge member 11 vc is
almost the same as in the case of the small vibration and convective motion, therefore The edge
member can be operated linearly.
As described above, according to the present invention, it is possible to produce a high fidelity
speaker since the present speaker edge can be linearly operated at the time of small amplitude
operation and at the time of large amplitude operation. Become.
