De ghnáth, is caighdeán aontaithe é an breiseán cábla AV. Is é an tsamhail breiseán cábla AV ginearálta ná ceann lotus RAC, le trastomhas de 3.5mm. Is é an tsonraíocht jack headphone is coitianta é freisin agus is minic a úsáidtear é i bhfeistí iniompartha mar fhóin phóca agus ríomhairí glúine. Is féidir leis an gcábla AV 3.5mm tacú le feidhmeanna bunúsacha an headset, chomh maith le feidhmeanna eile cosúil le micreafón agus rialú sreang. Faoi láthair, tá na cáblaí coitianta AV ginearálta ar an margadh roinnte go príomha ina dhá chaighdeán: OMTP agus CTIA.
Cábla cluasáin OMTP
The OMTP headphone jack standard is a Chinese national standard. OMTP headset is customized by the Open Mobile Terminal Platform Organization (OMTP) to unify the mobile device interface standard.
The plug of this type of headphone cable interface is divided into 4 sections, from the top end to the end of the plug are: left channel, right channel, microphone, ground. The interface standard corresponding to this wire standard is CTIA. The CTIA standard plug corresponding to the OMTP headphone cable is also divided into four segments, from the top to the end: left channel, right channel, ground and microphone.
Cé mhéad milliméadar atá sa breiseán cábla av uilíoch?
In addition to the AV connector specifications on mobile devices, the diameter of the general AV connector configured on computer devices is also 3.5mm. The computer terminal interface is a stereo AV plug. There are three metal contacts on the wire plug, and there are two circles of insulators between the contacts as an isolation layer to prevent coupling and crosstalk. The wire plugs are arranged in the order of contacts: top - left channel; middle - right channel; low end - common end (also known as the ground end). Among them, the ground terminal is the longest contact with the largest area. The order of the arrangement of each contact in the plug corresponds to the plug.
Is é 3.5mm trastomhas an breiseán cábla headphone AV uilíoch, ach tá roinnt plocóidí cluasán gairmiúla ann freisin le trastomhas de 6.5mm. Cé gur cosúil go bhfuil an breiseán headphone agus an trastomhas ón taobh amuigh ar an méid céanna leis an breiseán micreafón (steirió), níl ach dhá theagmháil ar an breiseán micreafón agus trí theagmháil ar an breiseán headphone.
But no matter whether the diameter of the AV plug is 3.5mm or 6.5mm, mono or stereo, the conversion plug can be used to realize the specification conversion to meet the different needs of users.
