DESCRIPTION JPS55138887
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a conventional coaxial
speaker using a flat woofer, and FIG. 2 is a cross-sectional view of a coaxial speaker according to
an embodiment of the present invention. In the figure, 1 is a tweeter, 2 is a woofer 13 is a
pedestal, 5 is a male screw portion, 6 is a female screw portion, and in the figure, the same
reference numerals indicate the same or corresponding portions.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tweeter
attachment means of a coaxial speaker in which the tweeter is incorporated into a flat woofer
using a link-like flat diaphragm. Conventionally, in the speaker of this ridge, as shown in FIG. 1,
the tweeter -il + is screwed to the pedestal (3) fixed to the woofer (2) by the mounting screw 14
+. However, in such a structure, not only the installation of the tweeter (1) is not only timeconsuming, but it is also necessary to provide a flange for fixing the tweeter frame with the
scattered screw, and this flange is a tweeter It is necessary to make the outer diameter dimension
of the magnetic circuit of Therefore, in the speaker based on the limitation of the outermost
dimension of the tweeter, the design of the tweeter magnetic circuit is greatly restricted, and it is
difficult to obtain a high-performance one. In order to ameliorate the above drawbacks, this
device has external threads on the outer periphery of the tweeter frame, internal threads on the
tweeter mount, and screws in the tweeter itself. It is intended to provide a shape speaker. FIG. 2
shows an embodiment of the present invention, but an external thread (51 is cut on the outer
periphery of the frame of the tweeter (1), an internal thread + 61 is cut on the pedestal (3) for
tweeter mounting, and the tweeter itself As the tweeter-tl + frame does not need an unnecessary
flange by screwing in, the magnetic circuit of the tweeter can be designed to be large, and (2) a 2
"high performance unit can be obtained. As described above, according to the present invention,
not only the workability of the tweeter installation is improved, but also the tweeter is improved
in performance and the scattered village screw becomes excellent in appearance, and its
commercial value is large.
