The utility model further discloses an earphone. According to the left and right channel audio mixer and the earphone, the stereo audio mixing effects can be excellently realized.
Description
Technical field
The utility model relates to a kind of audio output apparatus, particularly relates to a kind of left and right sound channels device sound mixing and earphone.
Background technology
The demand to life along with scientific and technical fast development and people, earphone is widely used as a kind of audio output apparatus.
Earphone has In-Ear and ear suspension type according to wearing mode, although In-Ear Headphones is in use directly deep in the duct of people's ear, completely cut off outside sound, but caused the separating degree of left and right acoustic channels high simultaneously, left ear can only be heard the sound of L channel, auris dextra can only be heard the sound of R channel, can not reach the stereoeffect of audio mixing.
Utility model content
Based on this, be necessary to provide a kind of left and right sound channels device sound mixing and earphone that can reach stereoeffect.
A kind of left and right sound channels device sound mixing, comprising: He Youyin chamber, left sound chamber; Loudspeaker, comprising being placed in the first loudspeaker in described left sound chamber and being placed in the second loudspeaker in described right sound chamber; The first wire, is connected with described the first loudspeaker; The second wire, is connected with described the second loudspeaker; Also comprise sound field adjustment module, described sound field adjustment module is connected between described the first wire and the second wire, for realizing described left and right sound channels audio mixing.
In an embodiment, described sound field adjustment module is divider resistance therein, for realize described left and right sound channels audio mixing by dividing potential drop.
In an embodiment, also comprise the switch being connected with described divider resistance therein, for controlling the Kai Heguan of described left and right sound channels audio mixing.
A kind of earphone, comprises foregoing left and right sound channels device sound mixing.
Above-mentioned left and right sound channels device sound mixing and earphone, by setting up sound field adjustment module, make L channel can hear the sound of part R channel, and R channel also can be heard the sound of L channel simultaneously, thereby reaches well the stereoeffect of audio mixing.
Brief description of the drawings
Fig. 1 is the effect of sound field schematic diagram of sound equipment;
Fig. 2 is the effect of sound field schematic diagram of conventional earphone;
Fig. 3 is the effect of sound field schematic diagram of the utility model one embodiment.
Embodiment
Please refer to Fig. 1, is the effect of sound field schematic diagram of sound equipment.
Being in while playing music, is all generally to adopt sound equipment to manufacture a kind of effect of sound field of on-site tridimensional.As shown in FIG., left ear can be heard the sound of loudspeaker L channel, can hear again the sound that the R channel of loudspeaker transmits by air dielectric, and both form audio mixing.Same, auris dextra can be heard the audio mixing of the sound that loudspeaker right channel sound and L channel transmit by air dielectric.
In order to reach the effect of sound field of sound equipment as shown in Figure 1, reach the effect of sound field of expectation, when recording, tuner to increase the separating degree of left and right sound channels.
Please refer to Fig. 2, is the effect of sound field schematic diagram of conventional earphone.
In the time that user adopts earphone to reappear recording, because left and right receiver separating degree is heightened, left receiver can only be answered the sound of L channel, and right receiver can only be answered the sound of R channel, and sound field widens distortion.
Please refer to Fig. 3, is the effect of sound field schematic diagram of the utility model one embodiment.
A kind of left and right sound channels device sound mixing comprises the second loudspeaker 104, the first wire 106, the second wire 108, divider resistance RC and the K switch 1 that left sound chamber built-in the first loudspeaker 102, right sound chamber are built-in.
In the present embodiment, He Youyin chamber, left sound chamber can be set to In-Ear or ear suspension type according to the difference of wearing mode.
The first loudspeaker 102 and the second loudspeaker 104 be respectively be placed in described left sound chamber and right sound chamber in, be appreciated that in other embodiments, can also in described left sound chamber He in right sound chamber, plural loudspeaker be set respectively.
The first wire 106 is connected with the first loudspeaker 102, and the second wire 108 is connected with the second loudspeaker 104.One audio player is connected with the first loudspeaker 102 by the first wire 106, be connected with the second loudspeaker 104 by the second wire 108, so that the audio signal of audio player is transferred to respectively to the first loudspeaker 102 and the second loudspeaker 104 by the first wire 106 and the second wire 108, described audio player can be MP3, MP4, broadcast receiver etc.
In the present embodiment, divider resistance RC is connected between the first wire 106 and the second wire 108 as sound field adjustment module, for realize described left and right sound channels audio mixing by dividing potential drop.Be appreciated that in other embodiments, divider resistance RC can replace with other functionally similar components and parts.
In the present embodiment, the input resistance value of the first loudspeaker 102 is R
1, the input resistance value of the second loudspeaker 104 is R
2, the resistance value of divider resistance RC is R
3, establish:
α=R
1/(R
1+R
3)，β=R
2/(R
2+R
3)。
By the dividing potential drop effect of divider resistance RC, the output resistance that makes the first loudspeaker 102 is R
1+ α R
2, the output resistance of the second loudspeaker 104 is R
2+ β R
1thereby, make left ear and auris dextra all can hear the audio mixing of L channel and R channel.
In addition, in the present embodiment, be also provided with the K switch 1 being connected with divider resistance RC, for controlling the Kai Heguan of described left and right sound channels audio mixing.
A kind of earphone, comprises above-mentioned left and right sound channels device sound mixing.
Above-mentioned left and right sound channels device sound mixing and earphone, by setting up divider resistance, make L channel can hear the sound of part R channel, and R channel also can be heard the sound of L channel simultaneously, thereby reaches well the stereoeffect of audio mixing.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
