DESCRIPTION JPS62281698
[0001]
The present invention relates to a speaker device for audio equipment such as a cassette tape
recorder with a radio receiver and a radio receiver. In the case of reproduction, the direction in
which the sound is generated in the front direction with respect to the front of the speaker has
been mainstream. FIG. 4 shows a conventional speaker apparatus. In FIG. 4, 11 is an apparatus
body, and 12L and 12R are left and right speaker boxes which are detachably mounted on the
apparatus body 11 on the left and right sides of the apparatus body. . The left and right speaker
boxes 12L and 12H have low-pitch speakers 1L and 1R and high-pitch speakers 2L and 2R,
respectively. Then, the bass speakers I L and 1 R and the high-tone speakers 2L and 2R provided
in the left and right speaker boxes 12L and 12R are mounted in the same direction toward the
front of the speaker boxes 12L and 12H, The directivity of each of the speakers IL, 1R, 2L, 2R
does not change regardless of whether the left and right speaker boxes 12L, 12R are present on
any of the left and right side surfaces of the device main body 11. Problems to be solved by the
invention However, in the conventional device, as shown in FIG. 4, since the high-pitched speaker
and the low-pitched speaker are directed to the respective speaker boxes, the spread of sound
changes. There is a problem that it becomes difficult for the sound to reach in the B direction
when each speaker box is turned in the inward direction in order to cause the problem. The
present invention solves such conventional problems, and provides a speaker device capable of
changing the spread of sound with a simple configuration without changing the direction of the
speaker box itself. Means for Solving the Problems The speaker device of the present invention
has one bass speaker and two treble speakers, and one of the two treble speakers is directed to
the front of the speaker box. The speaker apparatus of the present invention is characterized in
that the other high-tone speaker is attached to the left and right speaker boxes by being inclined
in different directions. There is no change in the directivity of the speaker for the high-tone
speaker among the two speakers and the high-tone speaker, but the other high-tone speaker

mounted on the left and right speaker boxes inclined in different directions is the left and right
speakers Regardless of the arrangement toward the front of the speaker box itself by replacing
the box, the above-mentioned inclined high-tone speaker Example Tsu and thus capable of
changing the rising following describes a speaker apparatus of the embodiment of the present
invention with reference to the drawings.
FIGS. 1, 2 and 3 show an embodiment of the present invention. In FIGS. 1 to 3, 11 is a device
main body, 12L. Reference numeral 12R denotes left and right speaker boxes which can be
detachably attached to the device body 11 on the left and right side surfaces of the device body
11. The left and right speaker boxes 12L. In 12RK, low-pitch speakers 1L, 1R and two high-pitch
speakers 2L, 2R, 3L, 3R are arranged. Here, the bass speakers 1L, 1R and one high-tone speaker
2L, 2R provided in the left and right speaker boxes 12L, 12H are attached to the front of the
speaker boxes 12L, 12H, and the high-sound speaker 3L is mounted. , 3R are attached with the
speaker boxes 12L, 12R inclined to face different directions (outside) respectively. In such a
configuration, as shown in FIG. 3A, the left speaker box 12L is the left side of the device main
body 11. In the state where the left and right speaker box 12R is disposed on the right side
surface of the device main body 11, the left and right speaker boxes 12L and 12H for low-pitch
speakers 1L. The sound generated from the 1R and high-tone speakers 2L and 2R is generated in
the incoming direction, and the other high-tone speakers 3L and 3R will be generated in the B
direction. Also, as shown in FIG. The high-pitched speaker 3L is inclined by replacing the left and
right speaker boxes 12L and 12R. 3R makes it possible to change the spread of sound in the C
direction. Effect of the Invention As described above, according to the present invention, one of
the bass speaker and the two high-tone speakers is attached to the front of the speaker box, and
the other high-tone speakers are inclined in different directions by the left and right speaker
boxes. By attaching and attaching, by changing the left and right speaker boxes disposed on the
left and right of the device body, the spread of sound can be changed.
