PROBLEM TO BE SOLVED: To provide an easy-to-use earphone adapter with volume control
provided with a plurality of jacks so that a plurality of people with different hearing ability can
enjoy a television etc. comfortably at the same time. SOLUTION: A plurality of plug insertion
parts 2a and 2b, a plug terminal to be inserted into a plug insertion part such as a television, and
a volume for volume control are provided. First, the plug is inserted into an earphone jack of a
TV apparatus. Next, commercially available earphones are inserted into the plug insertion
portions 2a and 2b. Since a volume for volume control is electrically connected in the middle to
the plurality of plug insertion portions 2a or 2b, a person using a commercially available
earphone inserted in the plug insertion portion 2b is a dial for volume control. Move 1 to adjust

The present invention relates to an earphone adapter capable of adjusting the volume and having
a plurality of simple jacks so that a plurality of people with different hearing ability can enjoy a
television etc. comfortably at the same time.
[0002]
The conventional earphone adapter having a plurality of plug insertion portions has a function
that can be listened to by a plurality of people at the same time, for example, when a person with
a hearing loss and a person with a hearing use simultaneously Even if the volume is just good,
the volume is too low for the person with the hearing loss, and conversely, the volume just for
the person with the hearing loss is too large for the person with the hearing, It was difficult to

use.
[0003]
There is a method of using the conventional earphone adapter having the plurality of plug
insertion portions described above, and using the earphone with volume control in one plug
insertion portion, adjusting the volume according to the hearing and listening. This volumecontrolled earphone is expensive and is not widely used in general homes because of its limited
use.
In addition, generally there is a risk of disconnection or the like because the volume control is
attached in the middle of the earphone cord.
[0004]
In addition, when this earphone is used in a common facility such as a hospital, there are many
facilities where repeated use of earphones is generally prohibited from the viewpoint of
preventing infectious diseases, and therefore, the volume is expensive for each person. It was
uneconomical to have an adjustable earphone.

[0006]
The conventional audio equipment such as a television has only one earphone plug insertion
portion, and a plurality of people can not listen simultaneously, which is very inconvenient.
[0007]
In addition, the above-described earphone adapter having a plurality of plug insertion parts is
difficult to use because it causes pain in either of the hearing impaired people at the same time.
[0008]
When used in a common facility such as a hospital, there is a demand for an earphone adapter
having a common volume control function that uses a common inexpensive earphone and has a

low risk of disconnection.
[0009]
The present invention, as shown in FIGS. 1 and 2, is an earphone adapter comprising a plurality
of plug insertion portions 2a and 2b and a plug terminal 4 to be inserted into a plug insertion
portion such as a television.
[0010]
Furthermore, as shown in FIG. 7, it is an earphone adapter characterized by having a volume 7
for volume control in one of the plug insertion part 2a and the plug insertion part 2b.
[0011]
When the hearing aid person and the deaf person simultaneously use the earphone adapter of
the present invention in a room of a hospitalized patient's room and a nursing home in a hospital,
both the hearing person and the deaf person can enjoy it at a comfortable volume.
[0012]
Also, as another usage method, one person can enjoy a stereo program if used with both ears.
Of course, even if people with different right and left ear hearing skills can use it, it can be
enjoyed at a comfortable volume with both ears as well.
[0013]
In addition, the use of the earphone adapter according to the present invention makes it
unnecessary to use a commercially available earphone with an expensive volume control, and is
economical because it can be listened with an inexpensive earphone.
[0014]
In the case of the earphone adapter of the present invention, the volume control volume is less
likely to be broken like a conventional commercially available volume control earphone because
of the built-in adapter.

In addition, the form of use is economical because it is not necessary for an individual such as a
hospitalized patient to prepare by preparing a facility manager or a vendor who installs a
television at his own expense.
[0016]
Further, the present invention is simple in structure, small in size, light in weight, can be
manufactured inexpensively, and the method of use is very easy and highly convenient.
