DESCRIPTION JPH03191699
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
improvement of a speaker apparatus in which high and low speaker units are provided adjacent
to an enclosure. [Prior Art] FIG. 4 is a front view of a conventional speaker device of this type, in
which (3) is a woofer-1 (2) a tweeter and these are mounted adjacent to an enclosure (1) ing. (5)
is a front frame of the woofer (3), which is made of, for example, an aluminum dicist, and the
surface finish is flat. [Problems to be Solved by the Invention] As described above, since the hightone and low-tone speaker units are mounted adjacent to the enclosure as described above, the
sound radiated forward from the tweeter and There is a problem that, for example, phase
distortion occurs due to the combination of the sound coming out of the tweeter and reflected by
the front frame of the woofer. The present invention has been made to solve the abovementioned problems, and its object is to make the reflection of sound at the front frame of the
woofer occur randomly to reduce one phase distortion. [Means for Solving the Problems] In the
speaker device according to the present invention, a portion of the sound emitted from the towers is provided with a plurality of uneven portions provided on the front frame of the woofer
adjacent to the tow-outer. It is made to diffusely reflect. [Operation] In the speaker device
according to the present invention, the gasket provided on a part of the front frame of the woofer
diffusely reflects the sound received from the tweeter to reduce the phase distortion. An
embodiment of the present invention will be described below. That is, in FIG. 1, (1) is an
enclosure in which a woofer (3) and a tow eater (2) are attached adjacent thereto, and a front
face of the woofer (3) adjacent to the tow eater (2). A gasket (4) made of an elastic body having a
large number of concavo-convex portions on one surface is fixed in a polymerized state at theportion of the frame (5). As described above, in the speaker device according to the present
invention, the woofer and the tweeter are adjacent, and part of the sound emitted from the
tweeter is reflected by the front frame of the woofer. In the front frame (5) of (3), a gasket (4)

having a large number of concavo-convex portions on one surface is fixed in a polymerized state
at an adjacent portion to the tweeter (2), the tweeter (2) The sound received from the lens is
diffusely reflected by the above gasket (4) and therefore does not cause phase distortion in
combination with the sound radiated forward directly from the tweeter. In the case of attaching
the above-mentioned gasket of the present invention to the woofer of the present invention, the
case of the three-in-one speaker type is similarly applied to both the squawker and the woofer. It
may be attached.
Also, in the case of one type of 4-in-one speaker, it may be similarly mounted on a honey-hidded
bath and a woofer. Since the speaker device of the present invention is configured as described
above, the phase distortion due to the reflected sound from the front frame of the woofer is
eliminated, whereby a reproduced sound with little noise can be obtained. In addition, it is
possible to suppress the vibration of the front frame by polymerization of the gasket, and it is
possible to obtain a beautiful reproduced sound.
