A kind of Novel earphone
Technical field
The utility model relates to a kind of headset plug, relates in particular to a kind of Novel earphone that the accompaniment tone in the song can be extracted and play separately.
Background technology
Traditional earphone generally only plays and prolongs the effect of answering route, and the length of earphone is expanded, and has increased user's use length.Perhaps the signal that transmits of signal source is public becomes a plurality of signal branch, uses jointly for a plurality of earphones.
And earphone generally is made up of plug, power amplifier and lead, and ground wire and left and right sound channels circuit are connected to form the loop, make left and right sound channels line output accompaniment tone and singer's sound, but can not play accompaniment tone separately, limited the function of earphone, inconvenient user uses.
Can advance thus, prior art needs further improvement and develops.
The utility model content
The utility model provides a kind of Novel earphone in order to solve defective of the prior art, earphone of the prior art has been carried out scientific and reasonable improvement, the user can be extracted the accompaniment tone in the song and play separately, expand earphone be used for be user-friendly in the space.
In order to solve the problems of the technologies described above, the utility model scheme comprises:
A kind of Novel earphone, it comprises headset plug, and headset plug comprises L channel circuit, R channel circuit, and wherein, the L channel circuit is connected with left power amplifier, and the R channel circuit is connected with right power amplifier, and left power amplifier is connected with right power amplifier; This Novel earphone also comprises the ground wire circuit, and the ground wire circuit is connected on the circuit between left power amplifier and the right power amplifier, and the ground wire circuit is provided with the ground wiretap.
Described Novel earphone, wherein, above-mentioned headset plug comprises shell, this shell is provided with the ground wire button that is used to control the ground wiretap.
Described Novel earphone, wherein, above-mentioned headset plug is provided with L channel tie point, R channel tie point and ground wire tie point, the L channel tie point is connected with the L channel circuit, the R channel tie point is connected with the R channel circuit, and the ground wire tie point is connected with the ground wire circuit, and the L channel tie point is positioned at the front end of this headset plug, the ground wire tie point is positioned at the rear end of this headset plug, and the R channel tie point is on this headset plug between L channel tie point and the ground wire tie point.
Described Novel earphone, wherein, above-mentioned shell comprises Plug Division and handle portion, and the Plug Division is connected with handle portion, and above-mentioned L channel tie point, R channel tie point and ground wire tie point are successively set on the Plug Division, and the ground wire button is arranged on handle portion.
The utility model provides a kind of Novel earphone, on the ground wire circuit switch is set, and when switch was in open mode, the ground wire circuit disconnected, and when switch was in closed condition, the ground wire circuit was connected; When the ground wire circuit disconnects, because there is the phase difference of half period in the people's acoustical signal in L channel circuit and the R channel circuit, so the voice mixed signal in L channel circuit and the R channel circuit superposes, voice is cancelled out each other, only remaining accompanying song sound, the user can listen to accompaniment tone separately, can check the quality of song simultaneously, make things convenient for user's operation, expanded the application space of earphone; When the ground wire circuit was connected, L channel circuit, R channel circuit and ground wire circuit formed the loop, play former song.
