DESCRIPTION JPS54114201
-Admiral 1, Title of the Invention 3, Measurement Description of the Invention The present
invention J relates to an improved overhead speaker system for sound pressure fM.
Conventionally, the sound range by the speaker becomes 'C' depending on the listening position,
and the train moves the listener's second stroke to the right and the backstroke also to the stone.
In this case, in the case of a two channel house, when the listener's name was located in the right
direction of the stone sby, it became a habit of haphazard and sternship. 本 明明 胤 で 点 'fc

the present invention. At the first failure, the radiated sound pressure F1. Consider an equilateral
triangle whose one side is the distance between the loudspeakers SP1 and SP2 of F, E, and let its
vertex be M, and draw iwDC parallel to the side so as to pass the vertex M. Then, the sound
pressure t-F at the point of the ton of the temperament localized at the middle point 0 of the
speakers SP and SP is considered so that the sound pressure at the point B on the previous y7
krza becomes the same sound pressure y. The sound pressure F is calculated as a vector
synthesis of the sound pressure r1 at point B due to the sound pressure y1 of the speaker SP1
and the sound pressure f at point B due to the sound pressure F2 of the speaker SP. Therefore,
the following equation is established. Therefore, from this formula (1), f and f become as follows.
And the radiation sound pressure F1 of the speakers sp, sp,. F2 is expressed as follows. Here, 2 is
the distance between the speaker SP and the point B, b is the distance between the speaker SP
and the point B, and sp,-, sp,-form an equilateral triangle, so sp, The distance between u and u is
the distance between UsSPs and 0. • The distance rco, 5, SP, and (3 (Dmkd ”/ 2; b. Therefore, 42
and b2 are as follows. Therefore, substituting the equations (4) and (2) into the equation (3)
results in the radiation pressure F, F2ta, etc. By the way, it becomes a relation of Pl limb α like
仄 at one angle β and θ. Therefore, the equation (5) represents the number of PAs of the
frequency α. From the above, the speaker sp1. sp, the compression direction% 4iE can be
changed to F1 and F in the above equation (5), and it is possible to reduce the migration of D-mu-

C on the gland of D-m-C centered on the point of 1 # J1. It becomes VC to be localized at 0 point
to the palace. In addition, a value at the point of α = 90, 1 to Fl-me 2-ω, but 7's l 'speaker: no
transmission for historical use-D-SP in FIG. In 'i'2)-0, 81iji self-style 5 is thresholded, and it is
perfect.
By the way, because it is more than Koshiki Castle to be affected by the field service, it is
necessary to use two loudspeakers or a tweeter, or use a loudspeaker of a bipolymer
diaphragm.め る 掘 り よ う よ う 第 第 Page ボ Page Page Page Page Page Page Page Page Page

ridges at both ends. Therefore, by changing the curvature of this bipolymer steel plate to make
the stress S a function of the cutting formula (5), the angle α of the C phrase C C is its radiation
it薊 i self-style (! 1) I (I can add 67) 2, to celebrate this cocoon fingering 1 by providing a fin on
the front of the speaker is also ugly O more than not from · · according to the invention,
regardless of the listening position of the position of the sound It is necessary to make it constant

direction of ス ス チ ャ ン ネ ル チ ャ ン ネ ル of the stereo channel ス テ レ オ. Therefore, it is
effective to divide into a large number in the listening room.
