Detailed Description

In order to make the technical problems, technical solutions and technical effects achieved by the present invention more clear, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings, and obviously, the described embodiments are only some embodiments, not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

In the description of the present invention, unless expressly stated or limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, detachably connected, or integral to one another; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

As shown in fig. 1, the utility model provides a noise reduction earphone, this noise reduction earphone can be bluetooth headset, and noise reduction earphone can include left earphone unit and right earphone unit, and left earphone unit and right earphone unit all can include into ear main part 10, mainboard, extension 20, and of course, noise reduction earphone also can only include an earphone unit, like left earphone unit or right earphone unit.

The in-ear body 10 may be a portion of an in-ear earphone placed in an ear of a human body, and the extension portion 20 is a portion leaking out of the ear of the human body, as shown in fig. 1, the in-ear body 10 generally has an included angle with the extension portion 20, preferably, the included angle between the in-ear body 10 and the extension portion 20 may be substantially 90 °, that is, the in-ear body 10 is substantially perpendicular to the extension portion 20, and when the in-ear body 10 is placed in the ear of the human body, the extension portion 20 may be attached to a face of the human body.

A main board (not shown) of the noise reduction earphone is disposed in the cavity formed by the ear insertion body 10, and a noise reduction microphone may be disposed on the main board, and the noise reduction microphone may be used to pick up ambient noise outside the earphone for active noise reduction, where the noise reduction microphone may be a moving coil microphone or a condenser microphone.

In the prior art, the sound collecting hole of the noise reduction microphone is generally formed in the ear inlet body 10 (indicated by reference numeral 30 in fig. 1) as shown in fig. 1, and when the user wears the earphone in the ear, the flowing air (air conditioning wind, fan wind, or natural wind) directly impacts through the sound collecting hole to press the diaphragm of the noise reduction microphone to generate a large wind noise. In view of this, the noise-reduction microphone sound-collecting hole 40 of the noise-reduction microphone according to the embodiment of the present invention is disposed at an end of the extension portion 20 away from the ear-insertion body 10, and the noise reduction microphone sound pick-up hole 40 is communicated to the noise reduction microphone through a sound pick-up channel in the relatively long extension portion 20, since, in practical applications, after the user wears the noise reduction earphone, the end of the extension part provided with the sound pickup hole 40 of the noise reduction microphone is generally directed downward, the air flow direction is generally perpendicular to the ear-entering body 10, such as air conditioning wind, fan wind or natural wind, or air convection generated by the user swinging his head or moving the user directly impacts the ear-entering body 10, as shown in fig. 1, the direction F is the direction of air impact when most earphones are worn, and it can be seen from fig. 1 that the air flowing in the direction F cannot directly impact and press the noise reduction microphone on the main board in the ear body 10 through the noise reduction microphone sound collecting hole 40. The embodiment of the utility model provides a microphone that will fall makes an uproar picks up sound hole 40 and sets up the one end of keeping away from income ear main part 10 at extension 20 for air flow direction F is roughly 90 contained angles with the hole axle that the microphone that makes an uproar picked up sound hole 40 that falls, makes the unable direct oppression of air that flows fall the vibrating diaphragm of the microphone that makes an uproar, thereby has reduced the wind of earphone and has made an uproar.

As shown in fig. 2, in the utility model discloses an optional embodiment, the mainboard still is provided with wave filter 50, the microphone of making an uproar passes through wave filter 50 and is connected with the speaker 60 electricity of making an uproar earphone of making an uproar that falls, the microphone of making an uproar sound collecting hole 40 that falls through keeping away from the one end of income ear main part 10 at extension 20 promptly, the wind that the microphone of making an uproar that falls picked up of making an uproar has become less, can eliminate less wind after rethread wave filter 50 filters and make an uproar, make the signal that the wind made an uproar produced filtered and remove unable arrival speaker 60, greatly reduced the noise in the earphone of making an uproar, wherein, wave filter 50 can be any digital filter that can filter.

Certainly, the noise reduction microphone pickup hole 40 can be provided with a dust screen and a wind-proof screen, and the dust screen and the wind-proof screen can be made of plastic, nylon or other fabrics. The dust screen can block dust and get into the microphone of making an uproar that falls, prolongs the life of the microphone of making an uproar and makes the microphone of making an uproar that falls have good pickup environment, prevents wind the velocity of flow that the net can further reduce the air current, alleviates the oppression of air current to the microphone of making an uproar, further reduces the wind and makes an uproar.

As shown in fig. 1, in an optional embodiment of the present invention, the main board is further provided with a call microphone, the ear-entering main body 10 is provided with a call microphone sound-collecting hole 30 which can be communicated to the call microphone, wherein the call microphone can be a moving coil type or a capacitor type microphone, and the call microphone sound-collecting hole 30 can transmit the sound of the user when the noise reduction earphone is used for calling.

The utility model discloses earphone of making an uproar falls includes the income ear main part, extends the extension that goes out from income ear main part one end and is located the mainboard of going into the ear main part, and this mainboard is provided with the microphone of making an uproar, and the one end that the ear main part was kept away from to the extension is provided with the microphone of making an uproar and picks up the sound hole of making an uproar, and the microphone pickup hole of should making an uproar falls feeds through the pickup passageway in the extension to the microphone of making. The embodiment of the utility model provides a to fall the microphone pickup hole setting of making an uproar and keep away from the one end of going into the ear main part at the extension of earphone, avoided falling the microphone pickup hole of making an uproar and directly set up and cause the air current to directly oppress the vibrating diaphragm of falling the microphone of making an uproar and produce the problem that the wind made an uproar in going into the ear main part for the unable direct oppression of air current falls the vibrating diaphragm of the microphone of making an uproar, thereby reduces to fall the microphone received wind of making an.
