The number, type and arrangement of such drivers 31, 32, 33 are exemplary and therefore may
be designed differently in other alternative embodiments.
[0034]
As shown in FIGS. 4 and 5, a curved surface 36 having a constant curvature is formed in a
concave shape on the upper stage 35 of the front speaker 30A. The curved surface 36
corresponds to a part of a spherical surface and thus has a constant curvature corresponding to
the radius of the sphere. An insertion groove 37 is formed at a constant depth in the central
portion of the curved surface 36.

[0036]
The connection unit 110 interconnects the front speaker 30A corresponding to the first speaker
and the height speaker 70A corresponding to the second speaker. The connection unit 100
includes a shaft member 120 and a sliding member 130.
[0037]
The shaft member 120 is composed of an insertion portion 121 and a bed portion 122. The
insertion portion 121 is inserted and fixed in an insertion groove 37 formed in the upper stage
35 of the front speaker 30A. An external thread is formed on the outer surface of the insertion
portion 121, and an internal thread of an internal thread is formed on the inside of the insertion
groove 37. Therefore, it can be easily fixed to the insertion groove 37 of the insertion portion
121 of the shaft member 120 by screw fastening. The head portion 122 is exposed to the outside
without being inserted into the insertion groove 37.
[0038]
The sliding member 130 is in the form of a plate having a curvature similar to that of the curved
surface 35 of the front speaker 30A. The sliding member 130 has a long empty sliding groove
131 penetrating therethrough. The insertion portion 121 of the shaft member 120 described
above is inserted into the insertion groove 37 of the front speaker 30A after passing through the
sliding groove 131 of the sliding member 130. The sliding member 130 is formed with a pair of
coupling holes 132 and 133. The sliding member 130 is fixed to the height speaker 70A by
screws (not shown) passing through the coupling holes 132 and 133.
[0039]
The sliding member 130 of the connection unit 110 can slide along the curved surface 36 of the
front speaker 30A having the same curvature. Accordingly, when the sliding member 130 slides
along the curved surface 36 of the front speaker 30A, the height speaker 70A coupled to the
sliding member 130 rotates in the vertical direction. Here, the vertical rotation of the height
speaker 70A means that the height speaker 70A rotates around the first rotation axis α (see FIG.
10-05-2019
10
6) perpendicular to the vertical direction.
[0040]
The sliding member 130 of the connection unit 110 is rotatable about the shaft member 120.
Therefore, when the sliding member 130 rotates about the shaft member 120, the height
speaker 70A coupled to the sliding member 130 rotates in the left-right direction. Here, the fact
that the height speaker 70A rotates in the left-right direction means that the height speaker 70A
rotates about the second rotation axis β (see FIG. 6) in the vertical direction.
[0041]
The vertical and horizontal rotation of the height speaker 70A will be further described with
reference to FIGS.
[0042]
6 to 8 are diagrams for explaining the rotation operation of the height speaker provided in the
integrated speaker of FIG. 3, FIG. 6 is a perspective view showing an exemplary initial state, and
FIG. FIG. 8 is a perspective view showing the case where the height speaker is rotated upward
from the initial state, and FIG. 8 is a perspective view showing the case where the height speaker
is rotated rightward from the initial state.
[0043]
As shown in FIG. 6, the height speaker 70A has a soundproofing direction (or soundproofing
angle) P0 which is horizontal in the initial state.
[0044]
When the height speaker 70A is rotated upward by a constant angle about the first rotation axis
α arranged in the direction orthogonal to the vertical direction, the height speaker 70A is
inclined upward as shown in FIG. 7 It comes to have a soundproofing direction P1.
[0045]
When the height speaker 70A is rotated to the right by a constant angle about the second
rotation axis β disposed in the vertical direction, as shown in FIG. 8, the height speaker 70A has
a soundproofing direction P2 biased to the right.
10-05-2019
11
[0046]
As such, the height speaker 70A of the integrated speaker 100A can be rotated in the vertical
direction and in the horizontal direction relative to the front speaker 30A.
Therefore, the soundproofing direction of the speaker 70A can be appropriately adjusted in the
vertical direction and / or the horizontal direction.
Therefore, the listener can appropriately select the soundproofing direction of the height speaker
70A in consideration of the listening conditions and his / her preference.
[0047]
In addition, it was described that the length of the front speaker 30A roughly corresponds to 1
m.
Therefore, the height of the height speaker 70A is also approximately 1 m.
The height of the loudspeaker of approximately 1 m is relatively low compared to the case of
being attached to the wall of the room.
However, as shown in FIG. 7, since the soundproof direction of the height speaker 70A may be
set to face upward, the height speaker 70A can provide even if the height of the height speaker
70A becomes relatively low. The vertical acoustic sense is maintained.
[0048]
In the embodiment described above, the integrated speakers 100A and 100B are exemplified as
the height speakers 70A and 70B integrated with the front speakers 30A and 30B. In another
10-05-2019
12
embodiment, the integrated speaker may be a height speaker integrated with the rear speaker.
However, when the height speaker is integrated into the front speaker, the sound output from the
height speaker is reflected to the ceiling and easily transmitted to the listener. Therefore, it may
be desirable for the height speakers to be integrated with the front speakers rather than being
integrated with the rear speakers.
[0049]
As described above, according to the present invention, by providing an integrated speaker in
which the height speaker is integrated with the front speaker or the rear speaker, the
troublesomeness of attaching the height speaker to the wall of the room is eliminated. can do.
Furthermore, according to the present invention, the height speaker provided in the integrated
speaker is rotatable in the vertical and / or lateral directions, so that the listener appropriately
adjusts the soundproof direction of the height speaker in consideration of the listening
conditions and his / her preference. It can be selected.
[0050]
Although the preferred embodiments of the present invention have been described in detail with
reference to the accompanying drawings, the present invention is not limited to such examples. It
is obvious that those skilled in the art to which the present invention belongs can conceive of
various changes or modifications within the scope of the technical idea described in the claims.
Of course, it is understood that these also fall within the technical scope of the present invention.
