DETAILED DESCRIPTION OF THE INVENTION The invention is an improvement of the
headphone K1. In the case of the headphone, it is ik's feeling that the sound source is IBK within
the responsibility, because it is a direct writing in all cases f. It has a drawback and is cold. (11--1/1-1 "-1 l of the purpose of this invention company to solve the above-mentioned conventional
drawbacks, to be able to put out a feeling of listening to the music fist from rebuke from the
front, ie in the seat is there. A practical example of the present invention will be described in
detail below with reference to W4W1. In the figure, reference numeral (1) +1) denotes an
acoustic element incorporated in each of the left and right double horn main body forming a pair
and the + Hin double horn main body 11111'lK. These acoustic elements It (s! + Is the main body
of both horns + I + (in front of the central horizontal plane of 11 with an interval of the
atrioventricular zone, the acoustic element of the posterior position (11 is the anterior element of
the anterior position (sI In the same distance, each sound generation hole +5) of the horn main
body + 11115 is displaced in one direction from tji. (See <11112 m). Next K11 l acoustic
stringers (2 · + i (the distance to the dark will be explained). Children's 111V (-, 4)-JJl, 44! + (14t
(thf 141), that is, consider the company V 社 3 da O at normal temperature-it will be k. As shown
in FIG. 3, when there is no sounding headphone from the front, one point becomes denser at time
later than the point A at company A. 40 This place transferred this relationship to the headphone
J,-no-Δt 11 & e! l-Acoustic element 1 m 1 (! Even when driving at the same time, a delay of ・ 11
can be obtained. (For example, in the case of Δgm5 GS third%, o4, element 1! The element 111 is
different to +. +) At this time, it is natural that it is necessary to balance the volume in the sound

2 I (音 2). Also, 1 shown in FIG. In the example shown in the figure, both acoustic elements (the
axes of the zI series 1 are inclined and fixed so as to face the center sK of the sound generation
hole product of the horn body il +). And again to the aS diagram 1! In the dance / example, fix the
percussive acoustic system 1 at a parallel position, and place the acoustic trumpet 121 at that
portion between the company amplifier and the other. The Toden 40 element &&) which is
equivalent to 10Jl was added. Other symbols in the figure) Company ear pad cushion, (6)
Dustproof cloth, (Ma) indicates a suction material. In the above description, Δg-344% is used, but
in this case interference occurs with / QOOOB, and the positional relationship of the ear is
unnatural, so the actual value of # 'iΔ is considerably smaller than 3% It is.
Since this device has a composition like a samurai, even if (嘗) can utter a music dispute, it can
give a feeling of wl 音 楽 from the front, lll-of the music in a sting seat. Since the sound element
of wi & is built in each of the L and 1 main bodies, the sound effect can be improved and
improved, for example, the da-channel sound field can be reproduced.
