The front and rear surfaces of terminal body 100 are respectively formed two display screens that can be worked independently.Terminal body 100 is general integrally disposed
There are a local earpiece 103 and a local microphone 1042.Local 103 sounding of earpiece is local towards one of display screen side
The sounding of microphone 1042 is downward.
The each embodiment of the method for the present invention is proposed based on above-mentioned 100 hardware configuration of mobile terminal, communications network system.
Embodiment 1
As shown in figure 4, it is whole to be applied to double screen the embodiment of the invention provides a kind of stereo implementation method of double screen terminal
End, the double screen terminal include two display screens, the microphone that double screen terminal bottom is arranged in and are arranged in the double screen
The earpiece of Bidirectional sounding at the top of terminal, this method comprises:
S101, the left channel signals of audio file and right-channel signals are respectively transmitted to the earpiece and the microphone into
Row plays；
When our listenings, can tell sound is transmitted by which direction, to substantially determine the position of sound source.
We are the reasons for having two ears due to us so the direction of sound can be differentiated.For example, having one in our right front
Sound source, then, since auris dextra is closer from sound source, sound just passes to auris dextra first, then just passes to left ear, and auris dextra is heard
Sound is more slightly more strong than the sound that left ear is heard.If sound source issue sound frequency it is very high, be transmitted to left ear sound some
It can be reflected back by the number of people, thus left ear is just not easily heard this sound.Two ears are this small to the feeling of sound
Difference passes in cerebral nerve, just enables us to judge that sound is from right front.Here it is usually said " ears effects
It answers ".
General recording is monophonic.Such as the different musical instrument sounds transmitted simultaneously from stage various aspects, it is passed by one
Sound device receives (or received and then mixed by several microphones), and synthesis is recorded at a kind of tone currents.Playback
When be also to be made a sound by a loudspeaker.We can only hear the composite sound of all directions difference musical instrument, and which cannot be differentiated
A musical instrument sound is come from which direction, that three-dimensional sense (space when imperceptible picture listens to music inside music hall
Sense).
If the spatial position of different sound sources can be reflected when recording, makes people in playback, just look like body
Face its border and directly hears that the sound source pronunciation of various aspects is the same.What this sound system was reset has relief sound, is exactly vertical
Body sound.
It is respectively coupled on two amplifiers at a distance of not far microphone with two before the lights, then amplifier is put
Variable-current after big is connected in two loudspeakers corresponding with microphone position in another room.In this way as a performer
It is out-of-date from left to right, with going along singing to walk before the lights, and the audience in another room will feel as performer is just certainly
Oneself from left to right, with going along singing passes by the same in front.It is sent if recorded respectively from two microphones simultaneously with two recorders
The tone currents come；When playback, then two loudspeakers of playback simultaneously are put on position corresponding with microphone, the sound heard
Sound just has good three-dimensional sense, and here it is the recording of two channel stereos.Present stereo magnetic recording reproducer is two mostly
Sound channel.Its magnetic recording head and playback head is made by upper and lower two groups of coils, and the magnetic core of magnetic head is folded thickness rate and generally used
Tape recorder head magnetic core fold thickness want narrow half more, the track part on tape also just than common recorder record track part it is narrow
Half is more.In this way, just there is four track parts on a tape.In recording, sound is changed by two microphones for being arranged in left and right
It after tone currents, is amplified respectively by two sets of amplifiers in recorder, and is sent to two groups of coils of magnetic recording head respectively
Interior, when tape passes through magnetic recording head, the recording of two sound channels is just recorded on two track parts of tape simultaneously.Playback when
It waits, when tape passes through playback head, two groups of coils of playback head are respectively induced out the variable-current of two track parts, by two sets
Amplifier amplifies respectively, then resets out the sound of two sound channels respectively by being arranged in the left front and right two preceding loudspeakers of audience
Sound makes audience obtain three-dimensional sense.
Based on above-mentioned stereo principle, we are utilized respectively earpiece and words by setting left channel signals and right-channel signals
Cylinder plays, to realize the three-dimensional sense that audio plays.
S102, judgement simultaneously determine the current screen towards human body in two display screens；
Only one display screen of present terminal, we are typically all towards display screen, in order to obtain well when in use
Sound effect, general microphone is arranged in terminal bottom, and sounding is towards being downward, and earpiece is then in display screen surface
Bottom, sounding meet the positional relationship of our mouthes and ear towards being perpendicular to display screen.But in double screen terminal
In, due to user be free to using two display screens any one, thus in the case where existing earpiece is arranged one,
Sounding just affects audio frequency effect towards one of display screen is perpendicular to.
S103, the switching earpiece sounding direction, so that the earpiece sounding direction is consistent with the current screen.
It is known that influencing the mainly earpiece position because of audio frequency effect, we set earpiece to switch sounding
Direction, such as the same earpiece allow one of them towards opposite earpiece by change earpiece vocal structure, or setting two
It works towards the earpiece of face, avoids double screen terminal in use, needing continually to adjust terminal location.
Wherein, switching the earpiece sounding direction, so that before the earpiece sounding direction is consistent with the current screen,
The method also includes:
The earpiece that the terminal is arranged has former and later two sounding directions, and the sounding direction of earpiece described in control selections.
As shown in figure 5, two earpieces 103 are arranged at the top of the terminal 100, the sounding of two earpieces 103 is towards on the contrary.
As shown in fig. 6, being opened by by the voice coil of earpiece 103 and switching switch connection by main control board control switching
It closes, so that the one of work of two earpieces 103, another is standby.
Optionally, an earpiece is set at the top of the terminal, earpiece setting there are two vibrating diaphragm, a voice coil and
One permanent magnet assembly, the voice coil both ends are separately connected the vibrating diaphragm, switch the working condition of two vibrating diaphragms, listen described in adjustment
The sounding direction of cylinder.
Specifically, as shown in fig. 7, the earphone structure 300 includes: annular framework 310, magnetic core 340, annular permanent magnet
320, voice coil 330 and two vibrating diaphragms 360；The annular permanent magnet 320 is mounted in the annular framework 310, the magnetic core
340 are arranged in the annular permanent magnet 320, and the voice coil 330 is set on the magnetic core 340, and the vibrating diaphragm 360 is set respectively
