DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a horn speaker for
stereo reproduction. A horn-type speaker is known as one insertion of a speaker that converts a
彷 奄 に 音 into sound-like vibration. Speakers of C are generally good at changing the efficiency
of electricity-numbers and can easily enhance the means of sounding @, and the cedar shape of
the horn that is the case is superior in design because it is elegant ing. Η) When performing
stereo reproduction with this L ス ピ ー カ speaker, the 2 ス ピ ー カ ス ピ ー カ speaker
corresponding to the famous channel on the left ... ... t t ス ペ ー ス ス ペ ー ス ス ペ ー ス ス ペ

a problem of rising. This one scheme is a horn type flare which can be performed in stereo
format with an arrangement of 1 to 1 which has a composition of F to-1 and a shadow that is
elegant and inexpensive. Providing power is one vinegar. The following will describe the Val
according to one aspect of the invention of C with reference to FIG. FIG. 1 is a perspective view
showing an actual 1 ml × 11 pieces of the present invention, and FIG. FIG. In the figure, 1 is a
horn so that the cross section at the horn will be an ex-Bornnenyal curve. In this case, 2 is a
partition which forms the inside of the Toki horn 1 into two left and right ends, and 3 is a
housing which attaches and holds the base t @ of the 1st horn 1. The rear part of the inside of
this body 3 # 'i is divided into two right and left compartments, and the left and right @ parts of
the housing 3 corresponding to each of the compartments have openings 4 and r Each is in
communication. On the base end of the left famous section of the throat part! ! 1ffl A pair of
sound sources 5m, 5b which receive electrical signals corresponding to the left and right
channels of the stereo from an electrical device not shown and convert the electrical signals into
** signals. For example, the dynamics beaker holding We 614 is attached. FIG. 8 is a diagram

schematically showing the construction of this invention, and the inside of horn I is li1! ! The
inside of the case 3 which is formed in the left and right 2 sections by the wall 2 and which
cancels and holds the horn l is built up in the left and right 2 sections. Communication is made to
the left and right name compartments of the horn 1. Then, the left and right sides of the casing 3
are provided with “red mouth 4 and each section −I proximal end of the throat of the 1st horn
l-tt′L sound corresponding to the left and right channels of stereo $ 5m, 5bk It is provided.
Once, on top-a pair of sound rays 5a. 5b-erL It is possible to perform stereo reproduction by
giving the signal of the left channel of the stereo channel and the right chicken nelle, and it is
inexpensive as compared with the case of using two pairs of loudspeakers in shape or delicacy.
Furthermore, the conversion efficiency of electricity-sound-is also good-good.
Further, since the stereo reproduction sound is transmitted not only from the front face of the
horn I but also from the @ face of the housing 3, its sound quality also becomes good. In addition,
this invention is not limited to the above 4 "two practical examples. For example, in the upper
case 1 one example, the exponential horn is used but the conical horn, hyperbolic horn, etc. have
an appropriate shape. Horn? You may use it. 1. The broken part of the throat of horn l [II + @
shape ii oval shape may be circular or a pair of sound sources 5m, Fb may be a suitable shape to
facilitate piping, the inside of horn l is divided into two -To be completed partition 2? The
opening may not be provided at the opening south housing of the horn I, but may be formed in
an appropriate length t2 section inside the horn l. Horn you lv! 1) If an electric device tt such as a
radio, a tape recorder, a record blur, etc. is incorporated in the holding body 3, a compact stereo
reproduction '1k11 can be obtained. As described in detail above, this invention comprises the
horn in the left and right two compartments-and the internal disturbance of the housing 3 for
attaching and holding the horn in the left and right compartments as well! Because the left and
right sections of the 1st horn are different by 11c, and sound sources corresponding to the left
and right channels of the 1st horn are paid, the shape is elegant and the cost is low, *- It is
possible to provide a horn cedar speaker that can perform stereo reproduction with a simple
configuration to meet the dynamic output.
