Embodiment
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.Make an uproar in the description of earphone at wind resistance of the present invention, it will be appreciated that, "front", "rear", "left", "right", " on ", the orientation such as D score describes is only technical scheme of the present invention for convenience of description, instead of the orientation indicating the device of indication or element to have, therefore can not be interpreted as the restriction to technical solution of the present invention.
As shown in Fig. 1 to 5, wind resistance in a preferred embodiment of the invention is made an uproar earphone, comprise the earphone case 1 surrounding and form internal cavity, speaker unit, sound reception unit and noise reduction unit is provided with in cavity, noise reduction unit is electrically connected with sound reception unit and speaker unit, and noise reduction unit comprises circuit board 4 and Dolby circuit on the circuit board 4; The phonate hole 111 being communicated with earphone outside and cavity is provided with before earphone case 1; Speaker unit comprises loudspeaker 2, and the voice directions of loudspeaker 2 is towards phonate hole 111; Sound reception unit comprises the microphone 3 being provided with acoustic reception hole 31, and the side of earphone case 1 is provided with the sound hole 112 being communicated with earphone outside and cavity, and the position away from sound hole 112 in cavity is located in acoustic reception hole 31.
Particularly, earphone case 1 comprises hood-shaped procapsid 11 and hood-shaped back casing 12, and procapsid 11 and back casing 12 fasten to surround and form cavity; Phonate hole 111 arranges on the front casing 11, and sound hole 112 arranges on the front casing 11, and understandably, sound hole 112 also can be arranged on back casing 12 or at procapsid 11 with on the junction surface of back casing 12.Sound reception unit comprises the microphone 3 being provided with acoustic reception hole 31, and circuit board 4 is positioned at after loudspeaker 2.Outside noise through sound hole 112 enter in cavity laggard enter in sound receiver hole 31, received by sound reception unit; Noise is converted to the signal of telecommunication and reaches Dolby circuit by sound reception unit again, and Dolby circuit carries out the parameter that real-time operation goes out reverse sound wave; Launch reverse sound wave by speaker unit and carry out offset noise; So noise just disappears and has not heard.
Loudspeaker 2 are positioned in the middle part of cavity; Loudspeaker 2 are included in horn front 21 successively on voice directions and loudspeaker rear portion 22, and horn front 21 is in the form of annular discs, loudspeaker rear portion 22 in cylindrical shape, preferably, the dead in line at horn front 21 and loudspeaker rear portion 22.Loudspeaker rear portion 22 forms an annular space with the inner side of housing 1, is sent to acoustic reception hole 31 for sound from sound hole 112.Wherein, circuit board 4 to be positioned at after loudspeaker rear portion 22 and to be parallel to the direction of sound hole 112.The top of annular space is located at by microphone 3; On the straight line path of loudspeaker rear portion 22 between acoustic reception hole 31 and sound hole 112, the position of sound hole 112 than horn front 21 position rearward, and sound hole 112 is towards the non-voice side at loudspeaker rear portion 22.Such loudspeaker 2 position, the wind that can be entered by sound hole 112 is to external world carried out buffering and weakens, and the wind finally arriving acoustic reception hole 31 is weakened greatly, thus reduces the impact of wind on active noise reduction effect.
Wherein, the direction of sound hole 112 is from bottom to top, and the direction in acoustic reception hole 31 is that both directions are mutually vertical by before backward.The position of sound hole 112 is more forward than the position in acoustic reception hole 31, and the direction in acoustic reception hole 31 forward.While outside noise enters cavity, extraneous wind also can be blown into cavity through sound hole 112 unavoidably.If wind directly blows to acoustic reception hole 31, wind can be produced and make an uproar, and the vibrating diaphragm of microphone 3 can be made to produce vibration, have impact on the effect of active noise reduction.And sound hole 112 position of present embodiment and position, acoustic reception hole 31 are arranged, both the needs that sound reception unit receives noise had been met, turn avoid the wind being blown into cavity and directly blow to acoustic reception hole 31, thus decrease the generation that wind makes an uproar, turn reduce wind to make an uproar to the interference of earphone active noise reduction system, there is the effect that wind resistance is made an uproar.
Earphone case 1 is provided with the extension 121 stretched out downwards, and this extension 121 is arranged on back casing 12; Sound hole 112 is positioned at the front side of extension 121.When using earphone, earphone is worn on ear, sound hole 112 is located between extension 121 and human body skin, extension 121 keeps off the outside at sound hole 112, the wind blowing to sound hole 112 from outside is played to the effect cushioning and weaken, reduce wind-dryness, and reduce the intensity of the wind being blown into sound hole 112, there is the effect that wind resistance is made an uproar.
This earphone can be wired earphone or wireless headset.When this earphone is wired earphone, earphone cord 5 can enter cavity through extension 121, transmission of audio signal.When this earphone is wireless headset, extension 121 can not offer the passage passed through for earphone cord.
Wind resistance in present embodiment is made an uproar earphone, can reduce the generation that wind is made an uproar, and reduce the impact of wind on earphone active noise reduction effect, have the effect that wind resistance is made an uproar.
The foregoing is only the preferred embodiment of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various change, combination and change.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within right of the present invention.
