DETAILED DESCRIPTION OF THE INVENTION A pair of ear pads or a pair of ear horns connected
in a band (in this specification, they are collectively referred to as a headphone. ) Is essentially a
pinaural regenerator, and should listen to binaural recordings using dummy heddle etc., but it
should originally be a speaker system ? (1) ? ? ? iG и mi Also used to listen to stereo records.
This is one convenient use, and there is a significant difference between the sounds that are
heard when using a speaker system and the sounds that are heard when using a heddle. The
difference in sound is a composite record of monoural recordings (there are many such records
in the current record). In the case where the speaker system is used, there is a disadvantage that
the sound to be input to both ears does not enter one ear under the volume difference that can
be heard with the speaker system. The purpose of the proposal is to improve this point and to
make the sound heard when using a headphone approximate to the sound heard when using a
speaker system. It is like. 1 and 2, tl) +21 are left and right ear pads, + 31 + 41 are left and right
driver units (electrokinetic transducers), and (5) is a mounting flexible member connecting them.
In the present invention, the mounting flexible material (5) is a hollow ((2) (; member), and the
sound emitted from the driver unit + 31 + 41 reaches the ear pad 11 + 21 through two paths
respectively. One of these paths is a short path close to the ear pad + 11 + 21 and the other one
is a long detour path provided by the flexible material (5). (6) is an opening / closing material
provided in the middle of the detouring path. When the detouring path is blocked by the opening
/ closing material (6), the path from the driver unit (3) (4) to the ear pad fil + 21 is one for each

driver unit. Fell. In addition, the switch material (6) can also take an intermediate position where
the action of the above-mentioned detour path is adjusted as needed. The embodiment shown in
FIG. 6 compensates for the attenuation of harmonics caused by the sound from the driver unit (3)
(4) striking the wall of the hollow flexible member (5) at a right angle. A separate driver unino)
+31 +41 is provided opposite to the band fil +21. In this figure, tel +81 is an attenuation circuit
for adjusting the amount of sound emitted from the driver unit tal +41.
As can be understood from the above description, in the present invention, the sound from the
driver unit (3) and the sound from the driver (3) one driver unit both reach the wearer's ears and
reach the ears of the wearer. Since the sound to be reached is accompanied by a time difference,
the user can listen to the stereo record in a state close to that of the speaker system. If the user
dislikes the existence of two paths (for example, when listening to a pinaural recording), the
switch (6) may be closed.
