Stereo earphone for mobile phone-Adapter for connecting microphone set to stereo system
[0001]
The present invention relates to an adapter. In particular, the invention relates to an adapter for
connecting a stereo earphone-microphone set for a mobile phone to a stereo system.
[0002]
With the significant advances in wireless technology and semiconductor technology, mobile
phones are becoming increasingly lighter and functionally improved. Today, mobile phones are
an essential tool for communicating with people in everyday life. In the past, most hands-free
earphone sets (phone-phone-microphone sets) were mainly used only as a means of
communication. However, in order to expand marketing opportunities, many manufacturers are
10-05-2019

actively incorporating additional features into their mobile phones. That is, mobile phones are no
longer used merely as communication means.
[0003]
In recent years, manufacturers have successfully incorporated FM radio, MP3 and even videoaudio players into mobile phones. In order to fit into these new products, single-channel handsfree earphones have been replaced by stereo earphones with separate right and left channels.
Thus, it is possible for the user to select and listen to an FM radio, MP3 or video-audio player
between conversations.
[0004]
Of course, mobile phones with built-in music program functionality are more expensive than
regular ones. In addition, hands-free earphone sets are also more expensive because stereo
headphones must have very high sound quality to meet the needs of the user.
[0005]
However, only high-quality stereo earphone-microphone sets can be connected to mobile phones.
Mobile phone earphone-microphone sets can be used in other stereo hi-fi systems (eg mobile
phones, bedside audio systems, and mobile audio systems including radio broadcast radio, CD,
MP3, MD) or PC multimedia devices (sound cards) Not designed to connect directly to the
socket). Currently, even the adapters that connect stereo earphone-microphones for mobile
phones to stereo systems are not on the market.
[0006]
For users who have mobile phones with music capabilities, it is no good to limit the application of
the stereo earphone-microphone set to only mobile phones. In particular, if the stereo earphonemicrophone set is not designed to be connected to a personal electronic multimedia device or
other stereo system, it would be a great waste of resources. In addition, if the user purchased
another earphone-microphone set to connect to a PC multimedia device or other stereo system,
10-05-2019

the user would have to carry the two earphone-microphone sets together.
[0007]
Therefore, one of the objects of the present invention is to provide an adapter capable of
connecting a mobile phone earphone-microphone set of a mobile phone to another stereo system
such as a computer multimedia device or another stereo audio device. It is.
[0008]
In order to achieve these objects and other advantages, and as embodied and expressly set forth
herein in accordance with the objects of this invention, the present invention is an adapter for
connecting a mobile phone earphone-microphone set to a stereo system I will provide a.
The stereo system comprises an earphone socket and a microphone socket. The mobile phone
earphone-microphone set comprises a left channel ear plug, a right channel ear plug, a
microphone and a first connector. The first connector is a four-electrode terminal having four of
a first electrode, a second electrode, a third electrode, and a fourth electrode. One of the
terminals of the microphone is connected to the first electrode of the first connector, and the

[0010]
It is to be understood that both the foregoing general description and the following detailed
description are exemplary, and are intended to provide further explanation of the claimed
invention.
[0011]
The accompanying drawings are included to provide a further understanding of the invention,
and are further included herein and constitute a part thereof.
The drawings illustrate embodiments of the invention and, together with the description, serve to
clarify the features of the invention.
[0012]
A detailed description of preferred embodiments of the present invention will now be given, as
illustrated in the accompanying drawings. Wherever possible, the same reference numbers are
used in the drawings or the description to refer to the same or like parts.
[0013]
As a result of careful research into stereo earphone-microphone sets for mobile phones currently
on the market, most earphone-microphone sets have only one connector (for example,
connection head or connection port) for connecting to a mobile phone. It became clear that it did
not have. Therefore, the connector usually has four electrodes, a ground electrode, an electrode
10-05-2019

connected to the microphone, an electrode connected to the left channel ear plug, and an
electrode connected to the right channel ear plug.
[0014]
Generally, computer multimedia devices or stereo audio devices have separate earphone sockets
and microphone sockets. On the other hand, most earplug audio systems have an earplug socket
but not a microphone socket. That is, the earphone-microphone set for most multimedia devices
and stereo audio devices must have two head connectors, one to connect to the microphone
socket and one to connect to the ear plug socket. The former is a head connector having two
electrode terminals connected to the ground and the microphone, and the latter is a head
connector having three electrode terminals connected to the ground and the left and right
channel earphones. The earphone head connector for the earplug audio system also has three
electrode terminals that connect to ground and to the left and right channel earphones. When
using an earphone-microphone set to connect to an earplug audio system (having one earphone
socket but not having a microphone socket), only the earphone head connector is effective and
the microphone head connector is in the dummy state.
[0015]
The number of head connectors and electrodes of the stereo earphone-microphone set for mobile
phones is different from the number of head connectors and electrodes required in computer
multimedia equipment, stereo audio equipment or most earplug audio systems. Therefore, the
head connector of the stereo earphone-microphone set for mobile phones can not be directly
plugged into computer multimedia equipment, stereo audio equipment or earplug audio systems.
[0016]
