The utility model provides a microphone subassembly. The microphone assembly is commonly applied to smart glasses; of course, it can also be applied to other head-mounted smart devices, such as smart helmets, head-mounted displays, and the like.
Referring to fig. 1 to 5, in an embodiment of the present invention, the microphone assembly includes:
a microphone 10 having a sound hole 11; and
the noise reduction part 20 is provided with a wind passing channel 21 and a sound transmission channel 22 communicated with the channel wall of the wind passing channel 21, and the wind passing channel 21 penetrates through the noise reduction part 20 and is provided with two exposed channel ports;
the sound hole 11 communicates with the sound transmission channel 22.
In this embodiment, the sound hole 11 of the microphone 10 is communicated with the sound transmission channel 22, the sound transmission channel 22 is communicated with the wind passing channel 21, and the wind passing channel 21 is arranged in a penetrating manner, so that when wind blows towards the microphone assembly, wind enters from one channel port of the wind passing channel 21 and then is directly blown out from the other channel port, thereby reducing the probability that the wind is filled into the sound hole 11 of the microphone 10 through the sound transmission channel 22, further improving the wind noise of the microphone 10, and improving the user experience; in addition, when a tiny foreign object (for example, dust) enters the wind passage 21 along with the wind from one passage opening, the tiny foreign object will also directly exit from the other passage opening along with the wind, so as to reduce the probability that the tiny foreign object enters the sound hole 10 of the microphone 10 through the sound transmission passage 22, and further avoid the occurrence of the failure phenomenon of the microphone 10 due to the blocking of the sound hole 11 by the tiny foreign object.
Optionally, the sound transmission channel 22 is communicated with the middle position of the wind passing channel 21. It can be understood that if the sound transmission channel 22 is communicated with the position of the wind passing channel 21 close to one of the channel openings, when wind blows from the channel opening, the wind can easily enter the sound transmission channel 22, which is not favorable for improving the wind noise of the microphone 10. In this embodiment, the sound transmission channel 22 is communicated with the middle position of the wind passing channel 21, so that the communication position between the two channels is not close to the two channel openings of the wind passing channel 21, and thus, when wind blows from any one channel opening of the wind passing channel 21 and flows through the communication position between the wind channel 21 and the sound transmission channel 22, the wind cannot easily blow into the sound transmission channel 22 and then reaches the sound hole 11 of the microphone 10, thereby being beneficial to improving the wind noise of the microphone 10.
Optionally, at least one passage port of the air passage 21 is provided with a dust screen to prevent micro foreign matters such as dust from entering the air passage 21 from the corresponding passage port, so as to achieve a dust prevention effect; and the wind speed can reduce when wind passes through the dust screen, and the wind noise prevention function is achieved to a certain extent.
Further, the microphone assembly comprises two air passing channels 21, one end of the sound transmission channel 22 is communicated with one air passing channel 21, and the other end of the sound transmission channel is communicated with the other air passing channel 21. In this embodiment, when wind blows towards the microphone assembly, if wind passing through one wind channel 21 blows into the sound transmission channel 22, the wind can also blow away from the other wind channel 21, so as to improve the wind noise resistance of the microphone assembly. It should be noted that the present invention is not limited to the number of the air passages 21, and in other embodiments, the air passages 21 may also be provided with more than three, and correspondingly, the sound transmission passages 22 need to have more than three connecting ends to communicate with the air passages 21 respectively.
Further, the two wind passing channels 21 are arranged in parallel, that is, the extending directions of the two wind passing channels 21 are the same or substantially the same, so that when wind with a wind direction along the extending direction of the wind passing channels 21 blows towards the microphone assembly, more wind in the wind direction can directly pass through the wind passing channels, and the wind noise prevention performance of the microphone assembly is further improved; in addition, the extending directions of the two air passages 21 are the same or approximately the same, which is beneficial to the processing and forming of the two air passages 21, for example, when the injection molding process is adopted for processing and the core pulling process is adopted for forming the two air passages 21, the core pulling is only needed to be carried out towards one direction, and the design of the injection mold is simpler. However, the design is not limited to this, in other embodiments, the two wind passing channels 21 may not be parallel, and it can be understood that the usage scenarios of the microphone assembly are often variable, wind may blow from multiple directions, and the arrangement of the two wind passing channels 21 that are not parallel can simultaneously reduce noise for wind in more directions.
Further, the air passage 21 linearly penetrates the noise reducing part 20. It can be understood that the distance of the straight line segment between the two points is shortest, that is, the distance of the air passing channel 21 which is linearly penetrated through between the two channel openings is shortest, so that the wind energy entering the air passing channel 21 can be blown out more quickly, and the probability of wind noise generation is reduced; in addition, since the overfire air duct 21 is arranged in a straight line, when the direction of the blown wind coincides with the extending direction of the overfire air duct 21, the wind can pass through the overfire air duct 21 completely without hindrance, thereby reducing the wind noise which may be generated when the wind passes through the overfire air duct 21.
Further, the sound transmission channel 22 is perpendicular to the wind passing channel 21. It can be understood that, when the wind passes through the wind passing channel 21, the wind tends to spread along the extending direction of the wind passing channel 21, so that the sound transmission channel 22 is disposed perpendicular to the wind passing channel 21, the wind direction is perpendicular to the extending direction of the sound transmission channel 22, and the wind is less spread in the direction perpendicular to the wind direction, so that the wind entering the sound transmission channel 22 can be reduced, and the wind noise can be reduced. Of course, in other embodiments, the sound transmission channel 22 may not be perpendicular to the wind passing channel 21, as long as the sound transmission channel 21 intersects with the wind passing channel 21, the wind entering the sound transmission channel 22 can be reduced to some extent, so as to reduce the wind noise.
Furthermore, the noise reduction part 20 is further provided with a sound pickup channel 23, one end of the sound pickup channel 23 is communicated with the channel wall of the sound transmission channel 22, and the other end is communicated with the sound hole 11, so that even if wind enters the sound transmission channel 22, the wind can reach the sound hole 11 through the sound pickup channel 23, and because the sound pickup channel 23 is more difficult to enter the sound pickup channel 23 compared with the turning of the sound transmission channel 22, the wind injected into the sound hole 11 can be further reduced, and the wind noise prevention effect of the product can be further improved.
Further, for the technical solution including the two wind passing channels 21, the sound pickup channel 23 is communicated with the middle position of the sound transmission channel 22, so that the communication position between the sound pickup channel 23 and the sound transmission channel 22 is not close to the two wind passing channels 21, and thus, no matter which wind passing channel 21 enters, the wind is difficult to flow into the sound hole 11 through the sound pickup channel 23, thereby being beneficial to improving the wind noise of the microphone 10.
Further, the sound transmission channel 22 is provided with a wind shielding protrusion 30 at a position adjacent to the sound pickup channel 23. It can be understood that the addition of the wind shielding protrusion 30 can increase the difficulty of wind entering the sound collecting channel 23 and pouring into the sound hole 11, thereby being beneficial to improving the wind noise of the microphone 10, and simultaneously reducing the probability that small foreign matters such as dust fall into the sound hole 11 through the sound collecting channel 23.
Optionally, the wind shielding protrusion 30 is disposed in a ring shape and surrounds a communication portion between the sound transmission channel 22 and the sound pickup channel 23, so that the probability that wind enters the sound pickup channel 23 and enters the sound hole 11 and the probability that small foreign objects fall into the sound hole 11 through the sound pickup channel 23 can be more effectively reduced. However, the design is not limited thereto, and in other embodiments, the wind shielding protrusion 30 may also be disposed as two transverse isolation ribs, in which case, two transverse isolation ribs are usually disposed and are respectively disposed at two opposite sides of the communication portion of the sound transmission channel 22 and the sound pickup channel 23.
When the wind shielding protrusion 30 is annularly disposed, optionally, the wind shielding protrusion 30 is annularly disposed, so that when wind flows through the sound transmission channel 22, wind energy smoothly passes through the outer wall surface of the annular wind shielding protrusion 30, thereby reducing the probability of generating additional wind noise by forming a vortex at the outer wall surface of the wind shielding protrusion 30.
The utility model discloses still provide an intelligent glasses, including the microphone subassembly, the concrete structure of this microphone subassembly refers to above-mentioned embodiment, because this intelligent glasses has adopted the whole technical scheme of above-mentioned all embodiments, consequently has all beneficial effects that the technical scheme of above-mentioned embodiment brought at least, and the repeated description is no longer given here.
Further, the noise reduction part of the microphone assembly is a part of a glasses leg of the intelligent glasses; it will be appreciated that the space available on the temple is relatively large, which may facilitate the provision of the noise reducer. However, the design is not limited thereto, and in other embodiments, the noise reduction part of the microphone assembly may also be a part of the frame of the smart glasses.
The above is only the optional embodiment of the present invention, and not the scope of the present invention is limited thereby, all the equivalent structure changes made by the contents of the specification and the drawings are utilized under the inventive concept of the present invention, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
