Description
Technical field
The present embodiments relate to USB interface technical field, particularly relate to a kind of USB being applicable to earphone
Interface inserts end and earphone.
Background technology
In electronic equipment and the Internet booming today, various portable terminals carry to user
For multiple operating function, these portability terminal units are to become a part for people's life, such as, hands
Machine, panel computer, e-commerce are stepped on.These portable equipment typically require charging or transmission data, need
USB interface to be had is with transmission data or provides charging.
Existing USB generic interface, has 4 lines, two power lines and two holding wires.Due to uUSB
Having DC source inside interface, two i.e. power supplys of metal claw outside interface, two, inner side is that serial data connects
Mouthful, connect instead and cannot communicate, and, when both positive and negative polarity connects inverse time, USB interface connected device can be burnt
Chip.Therefore, existing common USB interface uses the asymmetric design in both sides, prevents anti-inserted.
Owing to existing common USB interface has positive and negative, must go through the when of causing user to patch
Positive and negative just can be plugged, and makes troubles to user.The most novel USB interface, USB Type-C
Interface can overcome the difficulty of generic USB interface, and USB-C port obverse and reverse is identical, permissible
Hold the two-sided insertion of USB interface.USB Type-C interface meets the lightening trend of intelligent terminal, and to positive and negative
The support of plugging function more will significantly improve user's experience, the most more and more be quoted.
Earphone is also that portable equipment is commonly provided with, and earphone is a pair converting unit, and it accepts media play
The electric signal that device or receptor are sent, utilizes the speaker of ear to convert it into and can hear
Sound wave.Earphone is usually separable with media player, utilizes a plug to connect.
The benefit of earphone is in the case of not affecting other people, can listen to alone sound equipment；Also can separate around
The sound of environment, has side to the people used under noisy environment of making an uproar in recording studio, DJ, journey, motion etc. very much
Help.Earphone is former to be used on phone and radio, but prevailing along with portable electronic devices, ear
Machine is used for mobile phone, walkman, radio, portable electronic game sum digit reproducing apparatus for phonotape etc..Existing
Major part earphone is jack type, such as, and 3.5mm earphone interface of mobile phone.
In the prior art, on the one hand portable equipment to retain the USB interface of transmission data, another
Aspect there is provision of the promising earphone interface patching earphone.Portable equipment arranges multiple interfaces socket,
And too many interface is set on portable equipment and socket does not meets that portable equipment is light, thin, is easy to carry
Feature.Therefore, portable equipment patches various equipment with general-purpose interface and become trend.
As a example by smart mobile phone, the smart mobile phone of USB Type-C interface is used to have begun to become at present
Trend, USB Type-C earphone also arises at the historic moment.USB can be patched at USB Type-C interface
Type-C plug, it is also possible to patch USB Type-C interface headphones.
The existing earphone with USB interface and the connection of other equipment is all that the USB of employing standard inserts end
Interface, it is impossible to reach energy-conservation purpose.
Summary of the invention
The purpose of the embodiment of the present invention is to provide a kind of USB interface being applicable to earphone to insert end and earphone,
In order to solve the waste using USB interface to cause when being connected when earphone in prior art with other equipment.
The technical scheme that a kind of USB interface being applicable to earphone of the embodiment of the present invention inserts end employing is as follows:
USB interface is inserted end and is included four grounded pin, two passage configuration signal pins, two groups of difference
Signal pins and two auxiliary pins, wherein, grounding pin is used for ground connection, and passage configuration signal pin is used
In detection and configuration, a group in two groups of differential signal pins is for transmitting the analogue audio frequency R channel of earphone
Signal, another group in two groups of differential signal pins is used for transmitting the analogue audio frequency left channel signals of earphone,
In auxiliary pin one is used for transmitting analogue audio frequency microphone signal, and another in auxiliary pin is used for
Audio frequency ground connection.
The embodiment of the present invention also provides for a kind of earphone, and this earphone can pass through the above-mentioned USB being applicable to earphone
Interface inserts end and electrically connects with USB.
The technical scheme of the embodiment of the present invention has the advantage that the embodiment of the present invention passes through a retention criteria
The pin being suitable for for earphone in USB interface, thus reduce USB interface and insert the cost of end, reduce cost,
Improve commercial value.
