[Detailed description of the invention] This invention relates to the improvement of a stereo
speaker system among various audio equipments, and a high-range speaker is attached and fixed
to the front of a speaker box through a speaker holder having a unique structure, Unlike the
speakers in other pitch ranges, the direction of the high-pitched high-pitched sky (1) can be
adjusted freely according to the listener's position, the installation conditions of the speaker box,
etc. It is something that is devised. Next, the structure of the speaker system according to the
present invention and the operation thereof will be specifically described with reference to the
drawings of the embodiment. The drawing shows an embodiment in which the present invention
is applied to the most poppy two-way multi-speaker. (1) The high-pitched speaker (2) and the
low-pitched speaker (3) attached to the top and bottom of the front baffle plate (?) are basically
the same as the conventional speaker system, but in the case of the present invention, both
speakers (2) Of the (2) and (3), the treble speaker (2) is indirectly attached and fixed via the
speaker holder (4) having the structure as shown, without directly attaching it to the baffle plate
(1?) There is. The speaker holder (4) has a bowl-shaped main body (6) having a spherical
peripheral wall (54) and a concave surface (same radius of curvature) slidably in close contact
with the peripheral wall (-) outer peripheral surface of the main body (5). 6g) 8g) A bifurcated

support 1 (6) (6) and an opening (7) for mounting the treble speaker (2) at the front end of the
main body (5) In addition to screw holes (8) of several places, through holes (9) for all lead wires
of high-pitch speaker (2) are provided at the rear end, and the rotation range of high-pitch
speaker (2) In order to regulate, a stopper ?O consisting of annular ridges is empty at a
necessary point on the peripheral surface (5?) of the main body (5), and the high-tone speaker
(2) is a holder main body (5) as shown. It is housed inside and fixed by several screws (b) (b).
Further, the support ring for holding the main body (5) divides this into two left and right parts,
and the concave surface (6a [6a) of the inner peripheral portion is densely attached to the outer
peripheral surface of the main body (5) The high-pitched speaker (2) inside the speaker holder
(4) is fixedly fixed to the baffle plate (1a) of the speaker box (1) with several screws (2) (2) in a
state where it is turned up If the front end of the speaker (2) is gripped with fingers and pressed,
the inner pipe of the speaker can be changed by freely rotating along with the main body (5) in
any direction vertically and horizontally Is configured (3).
In the case of the present embodiment, a continuous groove (d) 0 is created in the central portion
of the inner surface of the support ring (fl) (6), and the inside of the groove (d) (2) is formed. An
anti-slip ring ?4 made of an elastic material such as rubber is fitted in the main body (5) holding
the speaker (2) when changing the direction of the high-tone speaker (2). It is fixed in a state
where it can be freely stopped at a desired position so that it does not move too much, and the
extra rotation of the high-tone speaker (2) is doubled with the stopper QIj provided on the outer
peripheral surface 1c of the main body Can be tied to As is well known, there are various types of
stereo speaker systems, and the number of speakers varies from single cone full range one shot
to 2 WAY or 3 WAY multi-speaker. Unlike high-range and low-range speakers that play high- and
low-range frequencies (4), the high-range speakers that reproduce the high to mid-high range
frequency band have very high directivity of the reproduced sound If the listener's sitting
position changes a little, the playback sound of both high and low speakers can be heard by
simply arranging the left and right speaker boxes in parallel in the wrestling room or facing them
inward. The balance of the sound may be distorted, and the sound quality and sound quality may
of course change the timbre and tone quality. One In order, in accordance with the position and
room 811 conditions the listener, each time, there is inconvenience, not to be adjusted to the
most suitable state subtly changing the orientation of the entire speaker box. Therefore, in the
speaker system according to the present invention, among the plurality of speakers provided in
the speaker box, the high-pitched speaker can be slid on a bowl-shaped main body having a
spherical peripheral wall and a peripheral wall outer surface of this main body Unlike the other
low-range speakers, the high-frequency speaker is mounted and fixed to the speaker box via the
speaker (5) holder consisting of a two-piece support ring with a concave surface with a concave
radius of curvature. Sideways so that the direction of the speaker can be freely adjusted with the
fingers, so the speaker with high directivity in the high-frequency range is most appropriate
according to the position of the listener or the reverberation condition in the room, etc. It is not
necessary to adjust the balance of the playback sound by adjusting the direction of the speaker

box each time as in the past, and it is always balanced by a simple handling operation. It is
possible to enjoy the highest sound quality of the one in which production cost structure of the
product is relatively simple to exhibit extremely significant practical effect I phase ? and it
inexpensive.
