The present invention relates to headphones (including earphones), and more specifically, to
simultaneously select a plurality of sound source devices and simultaneously separately select
voice information and music of different contents obtained from each sound source device and
combine them and listen simultaneously Related to headphones.
[0002]
Headphones including earphones are devices that convert electrical signals input from an
external sound source device into audio information or audio signals such as music and press
them against the pinna or ear canal opening for listening. A plug that has a speaker unit that

converts an electrical signal output from the device into an audio signal and propagates it as air
vibration, and one end is connected to the terminal of the speaker unit in the main unit and the
other end is detachably connected to an external sound source device It has a connection cord
with connectors such as jacks and jacks.
[0003]
Headphones have long been developed and used for listening to weak audio signals provided by
low-performance wireless communication devices and radio receivers by blocking the influence
of external sound, but to external open space As a result of the evaluation of the characteristics
that enable unremarkable personal listening that suppressed or blocked the influence of sound
signal propagation (so-called sound leakage) and external sound, the conversion from electrical
signal to sound signal in various sound source devices and Even after the ability of amplification
and propagation has been significantly improved and there is no hindrance to listening by
external speakers, its use has been greatly expanded, and the spread and penetration of various
portable sound source devices that are easy to carry-in particular, represented by the iPod
(registered trademark) Dramatically improved sound quality and increased capacity of digital
audio players and digital playback devices for moving picture still images, etc., daily recording of
various audio information by digital voice recorder Use - the result, listening use of the sound
source device in accordance with the headphones regardless of the indoor outdoor may be said
that has been established in the remarkable proceed already everyday life.
[0004]
As described above, headphones have been widely used at present due to the sound insulation
properties that suppress the influence of external sound and external sound leakage, but
conversely, one problem caused by this characteristic is also pointed out and solved.
Development and provision of headphones are also required.
[0005]
That is, as shown in FIG. 5, in the conventional headphones, one-to-one correspondence with an
external sound source device is absolutely premised, and the housing portion 15 in the main
body 11 of the headphone 1 used by pressing against the auricle or the ear canal opening Only
one or a pair of speaker units 13 to be compatible with a single external sound source device is
provided, and is compatible with the speaker units 13 via a single connection cord 14 provided
with connectors such as a jack 2 Connected to a single external sound source device, and
configured to listen to audio information and music provided by the sound source device, and
naturally, the number of sound source devices that can be listened by one headphone is limited
to one and a plurality of sound source devices It is not possible to simultaneously listen to audio
information and music of different contents provided by a single headphone.

[0006]
However, a variety of sound source devices are carried on a daily basis due to the reduction in
size and weight, and a large increase in the capacity due to digitization can save and accumulate
a large amount of various voice information and music and listen constantly. Requests such as
wanting to simultaneously listen to the content of the talk recorded in the voice and the audio
information of the foreign language course received through the FM transmitter or stored in the
audio player at the same time with the favorite music saved and accumulated in other audio
players simultaneously Not a few.
[0007]
Of course, the one-to-one correspondence between the external sound source device and the
speaker unit is not unique to the headphone but common to the speaker in general, but if it is a
speaker that amplifies and propagates the audio signal to the open space, By operating multiple
sets of speakers connected separately, it is possible to simultaneously listen to all of the different
audio information and music from each speaker, but multiple headphones can be worn
simultaneously, regardless of how many headphones with high sound insulation are prepared It
is not possible to simultaneously listen to different voice information and music from different
sound source devices, and even if the connectors of the connection cord terminal are branched, it
is possible to easily switch and use a plurality of sound source devices to meet the simultaneous
listening desired. It is not possible.
[0008]
In addition, if high-functional digital editing equipment is used, it is possible to simultaneously
input different audio information and music from a plurality of sound source equipment to the
editing equipment and immediately output it to a single headphone. The operation is not easy for
general sound source equipment users, and the request for simultaneous listening is premised on
easy and easy operation with a small, lightweight, portable external sound source equipment, so
it is large and portable. The need for simultaneous listening can not be met with this type of
digital editing device, which relies heavily on sophisticated and complex operations on the output
device side.
[0009]
Furthermore, by using relatively simple editing software, it is possible to combine or overlap
different voice information and music pieces of a plurality of sound source devices by a personal
computer, but this is a one-on-one correspondence between sound source devices and
headphones. Not only is it used, but it is not only troublesome to perform pre-editing, but it also
09-05-2019

wants to select and combine different audio information and music from different sound source
devices according to the situation and mood at the time of listening. In addition, the sound
information of any one of the sound source devices and the volume of music can not be
increased or decreased at the time of listening, or stop and restart can not be optionally operated
independently of other sound source devices.
[0010]
In the past, headphones were equipped with locking means such as a headband, etc., and the
large diameter ones used to cover and use the entire pinna were inserted into the ear canal,
holding the main body in the locking position of the ear canal opening The small diameter one
that is pressed and pressed is also referred to as an earphone, but at present the small diameter
so-called headphones that are not equipped with a headband and are hooked to the pinna by
hooks and used, and without cartilage plugs A large number of so-called earphones, etc., which
bring the main body into contact with the opening of the ear canal by locking, are often provided
as a result of losing their clear boundaries. .
The term "headphones" used in the present specification also applies to all so-called headphones
and earphones.

The headphone according to the present embodiment has the above configuration and is used as
in the illustrated embodiment, so that different electrical signals output from two different
external sound source devices 4a and 4b correspond to each other. As different speaker units
13a and 13b connected as described above are separately converted into audio signals, it is
optional to simply mount one headphone 1 having a pair of left and right main bodies 11 in
which the speaker units 13a and 13b are fitted. At the same time, it is possible to enjoy listening
and listening to audio information and music of two different types of contents selected and
combined at the same time.
[0023]
Further, in the headphones according to the present embodiment, the electric signals output
through the connection cords to the middle positions of the two types of connection cords 14a
and 14b connecting the external sound source devices 4a and 4b and the speaker units 13a and
13b are separately Since the volumes 3a and 3b are provided to adjust the volume of the audio
signal obtained on each speaker unit 13a and 13b side independently by adjusting operation
independently, for example, digital information behind the speech information of the speech
recorded on the voice recorder If you are listening to the audio player's music at the same time
and you want to concentrate on the important audio information part of the lecture, you can
lower the music volume only to the lowest level or raise the volume of the lecture part, etc. And
since it is possible to make timely and optional adjustment use, it is possible to truly meet the
request of simultaneous listening.
[0024]
In this embodiment, as the speaker units 13a and 13b fitted in the housing portion 15 formed in
the main body 11 of the headphone 1, permanent magnets are disposed in the hollow portion of
the voice coil to which the diaphragm is attached. It is needless to say that although a dynamic
type speaker unit is used to give an electric signal to a voice coil in a magnetic field to vibrate, it
is only for the convenience of explanation and can be implemented using any type of speaker
unit.
