問題点を有していた。 However, in the above configuration, the edge 6 of the woofer
Since a and 6b are significantly lower than the diaphragm 7 and the full plate 9, a deep groove is dug on a concentric circle around the tweeter's outer periphery. For this reason, the sound emitted forward from the tweeter is influenced by the concentric grooves, resulting in a problem in that the frequency characteristics of the tweeter take on a greatly wavy shape as shown in FIG.

できるものである。Structure of the Invention The coaxial flat plate speaker of the present invention has a bass diaphragm coaxially arranged around a treble diaphragm on substantially the same plane, and the bass diaphragm is arranged with an uproll edge. By combining the two edges, the volume of the part protruding from the surface of the bass diaphragm and the volume of the part entering from the surface of the bass diaphragm are equal or almost the same, thereby creating a flat sound. It is possible to obtain suitable frequency characteristics.

ある。DESCRIPTION OF EMBODIMENTS FIG. 3 shows the configuration of a coaxial flat speaker according to an embodiment of the present invention. In FIG. 3, 6a and 6b are the inner and outer edges of the diaphragm 7 of the woofer, which are constructed of up-rolled edges. Note that 1 is the equalizer for the tweeter, 2 is the diaphragm of the tweeter, 3 is the edge of the tweeter, 4 is the frame of the tweeter, 5 is the frame, and 7
Reference numeral 8 indicates a diaphragm of the woofer, 8 a frame of the woofer, and 9 a full plate, which are the same as those of the conventional example.
以上のように構成された本実施例の同軸型平板

うにツイータの周波数特性をフラツトにすること
ができる。 According to the coaxial flat plate speaker of this embodiment configured as described above, both edges 6a and 6b are uprolled as shown in FIG.
By making the volume A of the part a and 6b protruding from the surface of the diaphragm 7 and the volume B of the part descending from the surface of the diaphragm equal or almost the same, the sound produced by the grooves on the concentric circles around the outer circumference of the tweeter can be reduced. The interference effect of the edges 6a and 6b can be minimized, and the resonance of the edges 6a and 6b themselves can also be minimized. Therefore, the frequency characteristics of the tweeter can be made flat as shown in FIG.

スピーカを実現できるものである。Effects of the Invention The present invention provides an edge of the uproll bonded to a bass diaphragm so that the volume of the portion where the edge protrudes from the surface of the bass diaphragm is equal to the volume of the portion where the edge descends from the surface of the bass diaphragm. Alternatively, by making them almost the same, the frequency characteristics can be made flat without any increase in cost. Furthermore, since the edges come to the front, the outer periphery of the diaphragm becomes difficult to see, making it possible to realize an excellent coaxial flat-plate speaker that has the effect of making the appearance more beautiful.
