Description

A kind of earpiece holes attachment device of multi-line output
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
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the utility model earpiece holes attachment device.
Wherein, reference numeral is described as follows:Headset plug 1, audio distribution module 2, microphone mix module 3, One earphone jack 4, the second earphone jack 5, third ear machine transplanting of rice hole 6, the first audio conveyor module 11, the second audio conveyor module 12nd, the 3rd audio conveyor module 13, audio receiving terminal 14, the first audio conveying circuit 21, the second audio conveying circuit the 22, the 3rd Audio conveying circuit 23, audio receiving circuit 24.
Specific embodiment
As shown in Figure 1, a kind of earpiece holes attachment device of multi-line output, including headset plug 1, audio distribution module 2, Microphone mix module 3, the first earphone jack 4, the second earphone jack 5 and third ear machine transplanting of rice hole 6, headset plug 1 is internally provided with Audio delivery end and audio receiving terminal 14, audio delivery end connect the first earphone jack 4, the second ear by audio distribution module 2 Machine transplanting of rice hole 5 and third ear machine transplanting of rice hole 6, the first earphone jack 4, the second earphone jack 5 and third ear machine transplanting of rice hole 6 are mixed by microphone Sound module 3 connects audio receiving terminal 14.In first earphone jack 4, the second earpiece holes and third ear machine hole be equipped with L channel contact, Right channel contact and microphone contact.Audio delivery end include the first audio conveyor module 11, the second audio conveyor module 12 and 3rd audio conveyor module 13, the first audio conveyor module 11 connect audio distribution module 2 by the first audio conveying circuit 21, Second audio conveyor module 12 connects audio distribution module 2, the 3rd audio conveyor module 13 by the second audio conveying circuit 22 Audio distribution module 2 is connected by the 3rd audio conveying circuit 23, audio receiving terminal 14 connects wheat by audio receiving circuit 24 Gram wind mix module 3.
The audio signal collected is passed through microphone by the first earphone jack 4, the second earphone jack 5, third ear machine transplanting of rice hole 6 Audio receiving terminal 14 is sent to by audio receiving circuit 24 after the processing of mix module 3, audio receiving terminal 14 is by audio signal transmission To cell phone mainboard, the first audio conveyor module 11, the second audio conveyor module 12 and the 3rd audio conveyor module 13 believe audio Number audio distribution module 2 is sent to, each earphone jack is resent to after carrying out lossless distribution, for multiple earphones or stereo set It uses, the utility model further expands the earpiece holes function of mobile phone, and so as to terminate, a mobile phone can only be there are one Mike The limitation of wind, the mobile phone that also terminated are merely able to connect the limitation of an earphone.
