Description
Technical field
The utility model is related to technical field of electronic equipment, and in particular to a kind of multi-line exports earpiece holes attachment device.
Background technology
Nowadays, various music applications are increasingly developed out in smart mobile phone, and function is become stronger day by day.The earphone of existing mobile phone
Jack only has 4 contacts, is respectively microphone contact, earthing contact, right channel contact and L channel contact, and microphone contact will
Signal from microphone is transported to cell phone mainboard, and audio signal on cell phone mainboard is delivered to class by L channel, right channel contact
Like earphone equipment as signal source.Therefore, existing handset earphone jack can only receive a microphone and a pair of of earphone, with
The powerful audio-frequency function of mobile phone do not match that, for example, mobile phone KTV just need 2 or more microphone and the earphone of 2 or more,
The music function of mobile phone can not be extended by existing earpiece holes.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of earpiece holes attachment devices of multi-line output, it can
To solve the problems, such as that earpiece holes can only receive a microphone in the prior art and a pair of of earphone, function are single.
To solve the above-mentioned problems, the utility model uses following technical scheme：
The utility model provides a kind of earpiece holes attachment device of multi-line output, including headset plug, audio distribution mould
Block, microphone mix module, a plurality of earphone jacks, the headset plug are internally provided with audio delivery end and audio receiving terminal,
The audio delivery end connects a plurality of earphone jacks by the audio distribution module, and a plurality of earphone jacks are led to
It crosses microphone mix module and connects the audio receiving terminal.
Preferred technical solution, the earphone jack is interior to be equipped with L channel contact, right channel contact and microphone contact.
Preferred technical solution, the earphone jack include the first earphone jack, the second earphone jack and the third ear machine transplanting of rice
Hole.
Preferred technical solution, the audio delivery end include the first audio conveyor module, the second audio conveyor module and
3rd audio conveyor module, the first audio conveyor module connect the audio distribution mould by the first audio conveying circuit
Block, the second audio conveyor module connect the audio distribution module, the 3rd audio by the second audio conveying circuit
Conveyor module connects the audio distribution module by the 3rd audio conveying circuit.
Preferred technical solution, the audio receiving terminal connect the microphone mix module by audio receiving circuit.
After a plurality of earphone jacks of the utility model handle the audio signal collected by microphone mix module
Headset plug is sent to, audio signal is sent to audio by audio signal transmission to cell phone mainboard, headset plug by headset plug
Distribution module is resent to each earphone jack after carrying out lossless distribution, is used for multiple earphones or stereo set, this practicality is new
Type further expands the earpiece holes function of mobile phone, and so as to terminate, a mobile phone can only be also whole there are one the limitation of microphone
The limitation that a mobile phone is merely able to connect an earphone is tied.
Description of the drawings
