DETAILED DESCRIPTION OF THE INVENTION The stone of the present invention relates to an
earphone adapter for stereo tape recorders and other audio equipment designed to insert and
remove the IRs size plug of the headphone. For example, in the case of an outer shell sound by a
stereo tape recorder, a headphone is often used as a monitor, however, so-called conversion to
sound including such an outdoor full sound → 1 microphone in addition to the main body of the
tape recorder Tapes and batteries, etc. In addition, it is very troublesome to carry a relatively
bulky headphone, and the cord of the spatula (1) τ \ ′ ′ horn is disturbed in the actual
operation of the bell sound. There are no smaller ribs. SUMMARY OF THE INVENTION It is an
object of the present invention to provide a new and simple adapter that can monitor methireo
sound by means of mini plug earphones. In the following, a specific example of the earphone
adapter according to the present invention will be described with reference to the drawings. FIG.
1 is an oblique composite view showing an example of the present adapter and an outline of the
earphone to be inserted in and removed therefrom. The whole, (2) shows a rectangular crosssection body made of a synthetic resin molded product, and the negative side line of this body
(2), for example, the grip portion (2 ') as shown, A channel minijack sleeve (3), (4) is provided,
and a WN center portion of the body (2) has a column-sized plug (5) protruding therefrom. 16 +
aL connector, (7) indicates R connector, + 81 indicates earth connector, and say that each
connector is electrically insulated! でもない。 Also, +91 (9 people 9B) indicates a normal
earphone, and (2) i 5 'non-earle earphones (9) mini grab aωt L, R mini jack (3) and (4) K

respectively inserted To monitor the sound of the left and right channels. A ridge line shows the
main body of each earphone. FIG. 2 is a longitudinal sectional view showing an example of the
internal structure of the adapter (1), and in the case of this example, a separate body a3 to be
joined together with a butterfly body (2) K is provided. , Insulating material of the plug (5) and
each of them; molding integrally with the nectar, and insert molding M1), on the other surface of
the base a3. While attaching the elastic contact pieces a3 and a4 electrically connected to the R
connectors (6) and (7) respectively, @VC of the body (2) is a jack under hole a! Having relief
portions of the respective contact pieces B91 C14! 9 and ae are formed, and the abovementioned sleeves (3) and (4) are sharpened in the lower holes of the grips (the two ends of the
grip).
Both sleeves + 3L (41 and ground connector (8) are electrically connected). That is, when the
earphones 9A and 9B shown in FIG. 1 are inserted into the sleeves 3 and 4 and the earphone
nibs aI of the tips shown in FIG. Also, both base wedges are connected to the sleeves (3) and (4) k
respectively. (3) P> S Therefore, insert the plug (5) of the adapter (1) into the jack of the stereo
tape recorder and connect the earphones (9A) and (9B) to monitor the sound of the left and right
channels Can. However, as shown in FIG. 1 and FIG. 2, the adapter (the outer cover shape and the
internal structure of 11 and the like are merely examples, and it is needless to say that various
mIl other than the illustration can be adopted. Also, in the above description, the butterfly, when
applied to the stereo tape recorder when applying the present invention adapter, is a friend to
mention, its application is essentially a stereophonic audio device having a jack of standard size.
Thus, according to the adapter of the present invention, since stereo audio can be monitored
using a commercially available earphone, it is possible to remarkably educate the abovementioned inconvenience when carrying out a tape recorder to make an outdoor bell. It is also
useful for stereo sound equipment other than tape recorders although it is inferior in sound
quality to Ku, but it can be excellent for practical use, and can have nine effects.
