BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of an embodiment of the
phase difference headphone according to the present invention, and FIG. 2 is a wiring diagram,
since the left and right headphones have a symmetrical structure. Indicates 1 is a headphone
housing, 2 is a direct sound air circuit, 3 is an indirect sound air circuit, 4 ° 4 'and 5, 5' is a
speaker unit, 6 is a stereo source, 7 is an earpiece but 8 is a butt It is an opening net.
[Detailed description of the invention] The present invention is an air circuit provided inside the
headphone to create a sound wave of direct sound having a phase difference necessary for
sensing the direction of the sound source, and a longer air with a smaller diameter than the
phase difference headphone. By providing a circuit, making a sound wave with a phase difference
corresponding to an indirect sound, and adding it, the sound source is given a sense of distance,
and a stable sound image can be obtained out of the head. It is a phase-difference headphone,
and the structure is (1) f) -throw 100 (in the case of the core / mushi embodiment), it is the
following nine. The headphone housing 1 has a large-diameter short air circuit 2 with an exterior
curve inside it. A speaker unit 4.4 '(hereinafter referred to as a speaker unit as a unit) and a unit
5.5' are respectively configured in a shape (a left and right housing have a symmetrical structure)
including a spiral-shaped long air circuit 3 with a small diameter. (1. As shown in FIG. 2, the
mounting units 4 and 5 'and the units 5 and 4' are connected in parallel to the left and right of
the stereo source as shown in FIG. With this configuration, the listeners receive the sound source
as the direct sound from the units 4 and 4 'and the direct sound having a phase difference
through the air circuit 2 from the units 5 and 5' are given to both ears. The sound waves emitted
from the back of the diaphragm of the left and right units 5.5 'directly enter the sonic air circuit
2 via the spiral air circuit 3 and are directly transmitted as phase-delayed sound waves. The
sound wave of this phase difference is added to the sound and reaches the ear, but the sound
wave of this phase difference acts in almost the same way as the indirect sound in the room (2) L
7 11, 'inside sound field to make sense of distance With this button, a more stable sense of out-
of-head localization can be obtained. In this embodiment, the indirect sound uses the unit 5.5 'as
a sound source, but another unit) 4.4' may be used. According to the embodiment, in order to
give a phase difference capable of sensing the direction to the direct sound, an air circuit length
of about 100 may be sufficient, whereby the sense of localization of the sound image outside the
head can be obtained, but the indirect sound providing a sense of distance is The air circuit can
be made more than 250 wear, and by adding this, a more stable sense of out-of-head localization
can be obtained. The direct sound has almost the same sound pressure level. As described above,
since the phase difference headphone of the present invention physically generates direct sound
and indirect sound having phase difference, it is possible to obtain stable sound with a simple
structure without requiring any electrical signal delay device or the like. Sound localization like
the conventional headphones, pressure from left and right sound separation, no feeling of
fatigue, even if used for a long time without fatigue, and the sound quality known as synergy by
two speakers Improvements and richness are also obtained, so it is suitable for a wide range of
applications such as language learning, electronic music learning, studio monitoring, telephone
exchange, etc. in addition to regular (3) books You can get effective headphones
