Nowadays, music has become and has been integrated in one of indispensable important amusement function on mobile terminal.In order to reach better result of broadcast, music all adopts multichannel to record to produce stronger on the spot in person stereo in the time making.When in the time using earphone to play, the earphone of left and right ear obtains respectively the audio file of left and right sound channels and plays.
As shown in figure mono-, for the connection diagram of headset plug and mobile terminal earphone interface, described headset plug is risen to extend by end and is at least the first terminal 01, the second terminal 02 and the 3rd terminal 03, and mobile terminal earphone interface is respectively equipped with the first deck 04, the second deck 05 and the 3rd deck 06 in each terminal corresponding position.The first terminal 01 transfers to the left ear of earphone by the first deck 04 by left channel signals, and the second terminal 02 transfers to earphone auris dextra by the second deck 05 by right-channel signals, and the 3rd terminal 03 and the 3rd deck 06 are connected in ground jointly.User only has sound field when farthest reduction music is recorded by correct wearing mode, to improve music quality.
But, in the time that ambient light is excessively dark, the left and right sign of earphone is obvious not or be worn, can cause user cannot correctly identify left ear and the auris dextra of earphone, and be with anti-, now the left ear of user is heard the music of R channel, and auris dextra is heard the music of L channel, so that bring the sense of discomfort back to source of sound to user.For addressing this problem, user can only artificially exchange left ear and auris dextra conventionally, and this process is inconvenience comparatively, and may cause the winding of earphone cord, affects user and experience.
Summary of the invention
The purpose of this utility model is to provide the mobile terminal of interchangeable left and right acoustic channels output signal.It is simple to operate, easy to use.
The mobile terminal of the interchangeable left and right acoustic channels output signal that the utility model provides, comprise L channel audio output circuit for exporting left channel audio signal, for exporting right audio channel output circuit and the earphone interface of right channel audio signal, described earphone interface comprises the first deck and the second deck, it is characterized in that: described mobile terminal also comprises digital signal processor;
When described the first connection status, described L channel audio output circuit is connected with the first deck by digital signal processor, and described right audio channel output circuit is connected with the second deck by digital signal processor;
When described the second connection status, described L channel audio output circuit is connected with the second deck by digital signal processor, and described right audio channel output circuit is connected with the first deck by digital signal processor.
The mobile terminal of interchangeable left and right acoustic channels output signal described in the utility model compared with prior art tool has the following advantages:
Realize mobile terminal by described digital signal processor switches between the first connection status and the second connection status, described digital signal processor can be regarded the change over switch of L channel and R channel as, the process that realizes this conversion does not need artificial left earphone ear and auris dextra are exchanged of user, easy and simple to handle, can not cause the winding of earphone cord, promote user's experience.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in detail:
Fig. 1 is the connection diagram for headset plug in prior art and mobile terminal earphone interface;
Fig. 2 is the mobile terminal of interchangeable left and right acoustic channels output signal described in the utility model circuit block diagram in the time of the first connection status;
Fig. 3 is the mobile terminal of interchangeable left and right acoustic channels output signal described in the utility model circuit block diagram in the time of the second connection status.
Embodiment
Mobile terminal 6 as shown in Figure 2, comprise L channel audio output circuit 1 for exporting left channel audio signal, for exporting right audio channel output circuit 2 and the earphone interface of right channel audio signal, described earphone interface comprises the first deck 3 and the second deck 4, described mobile terminal also comprises digital signal processor 5, and described digital signal processor 5 is realized mobile terminal and switched between one first connection status and one second connection status;
When described the first connection status, described L channel audio output circuit 1 is connected with the first deck 3 by digital signal processor 5, and described right audio channel output circuit 2 is connected with the second deck 4 by digital signal processor 5;
When described the second connection status, described L channel audio output circuit 1 is connected with the second deck 4 by digital signal processor 5, and described right audio channel output circuit 3 is connected (as shown in Figure 3) by digital signal processor 5 with the first deck 3.
Described the first deck 3 is for coordinating with the first terminal 8 of peripheral earphone 7, and the second deck 4 is for coordinating with the second terminal 9 of peripheral earphone, and described the first terminal 8 and the second terminal 9 are all for received audio signal.Described the first terminal is connected with the earphone 10 of corresponding left ear or the earphone 11 of corresponding auris dextra respectively with the second terminal, and by extremely corresponding the audio signal transmission receiving earphone.
In the present embodiment, in the first connection status, mobile terminal is by the audio transmission of L channel to the left ear of earphone, and the audio transmission of R channel is to earphone auris dextra; In the second connection status, mobile terminal is by the audio transmission of L channel to earphone auris dextra, and the audio transmission of R channel is to the left ear of earphone.Realize the function that does not need user artificially to exchange earphone just can to switch earphone left and right acoustic channels.
Described mobile terminal also comprises a control switch, and described control switch control figure signal processor 5 is realized mobile terminal and switched between the first connection status and the second connection status.
Described control switch comprises physical button or virtual touching switch.When user's left ear is worn earphone auris dextra, and user's auris dextra is while wearing the left ear of earphone, and at this moment control switch can be switched to the second connection status by mobile terminal by the first connection status by control figure signal processor.After switching, the audio transmission of L channel is to earphone auris dextra, and the audio transmission of R channel is to the left ear of earphone, and because earphone auris dextra is worn on left ear, the left ear of earphone is worn on auris dextra, so after switching, what left ear was heard is L channel audio frequency, what auris dextra was heard is right audio channel.
