DESCRIPTION JPS62110395
[0001]
FIELD OF THE INVENTION The present invention relates to a speaker system for reproducing
audio such as audio and video. 2. Description of the Related Art In recent years, the speaker
system has more and more opportunities to be used as audio reproduction along with video
reproduction. Hereinafter, an example of the above-mentioned conventional speaker system will
be described with reference to the drawings. 6 and 6 show a cross-sectional view of a
conventional speaker system and a directivity characteristic view thereof. In FIG. 6, 1 is a cabinet.
2はスピーカユニットである。 FIG. 6 shows directivity characteristics in 6KH2. The
characteristics of the speaker system configured as described above will be described below. As
apparent from FIG. 6, the sound pressure of 90 ′ ′ and 18o @ is reduced by more than 20 dB
as compared to the sound pressure of d, ie, most of the energy radiated from the speaker unit 2
is on the front It is emitted in the direction. Problems to be solved by the invention However, in
the above configuration, the directional characteristics are poor, so there are many direct sounds
when heard from the front, and the problem is that the sounds tend to be less moist and have no
sense of presence I had a point. SUMMARY OF THE INVENTION In view of the above-mentioned
problems, the present invention provides a speaker system which can control the directional
characteristics freely and have a sense of presence and presence. Means for Solving the Problems
In order to solve the above problems, the speaker system of the present invention is attached to
the cabinet with the speaker unit facing up or down, and a cone movable or fixed above or below
it. It is equipped with a configuration called a shape equalizer. Operation According to the
present invention, the directional characteristics of the speaker system can be freely controlled
by the above-described configuration to provide the speaker system with a rich sense of
presence. Embodiment A speaker system according to an embodiment of the present invention
will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a speaker
system according to an embodiment of the present invention. In FIG. 1, 1 is a cabinet, 2 is a

speaker unit, 3 is a conical equalizer, 4 is an equalizer holding base, and 5 is an equalizer
mounting screw. Further, in FIG. 3, 1 is a cabinet, 2 is a conical equalizer, 2 is a conical equalizer,
4 is an equalizer holding base, and 6 is an equalizer mounting screw, which is similar to the
configuration of FIG. The operation of the speaker system configured as described above will be
described below with reference to FIGS. 1, 2, 3 and 4.
First, FIG. 2 shows the directivity characteristic of FIG. 1, and the sound pressure of oo is about
10 dB higher than the sound pressure of 1,800. When the conical equalizer 3 of FIG. 1 is moved
to the front, it becomes as shown in FIG. 3. The directivity characteristic becomes as shown in
FIG. 4 and the sound pressure of 18o0 becomes about 1 odB higher than the sound pressure of 0
°. As described above, according to the present embodiment, the directivity characteristic can be
freely controlled by providing a conical equalizer that can move or fix the speaker unit upward or
downward, and can be moved upward or downward. Can. Although the speaker unit 1 has a full
range in the embodiment of the present invention, it may be a 2-way or 3-way tweeter. Although
the conical equalizer 3 is provided on the speaker unit 2, the loudspeaker unit 2 may be provided
on the conical equalizer 3 and an embodiment thereof is shown in FIG. Also, the conical equalizer
may be a polygonal pyramid equalizer. As described above, according to the present invention,
the directivity characteristic is self-controlled by providing the movable or fixed conical equalizer
above or below the speaker unit facing upward or downward. To provide a speaker system that is
both moist and realistic.
