[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] like Figures 1 to 7As shown, the utility model provides a microphone, including a microphone body 1, the microphone body 1 includes a shell 10 and electronic components located in the shell 10, the shell 10 is provided with a sound pickup hole 11, and the sound pickup hole 11 is provided with a waterproof sound-permeable membrane; a waterproof sound-permeable component 2, the waterproof sound-permeable component 2 includes a mounting shell 21, an annular seal 22 and a waterproof sound-permeable membrane, the mounting shell 21 is provided with a mounting cavity 23 and an opening portion communicating with the mounting cavity 23, and a plurality of sound-permeable holes 24 are provided on the bottom surface of the mounting cavity 23; a part of the shell 10 is mounted in the mounting shell 21 through the opening portion, the sound pickup hole 11 is located on a side of the shell 10 close to the bottom surface of the mounting cavity 23; the waterproof sound-permeable membrane is provided at the sound pickup hole 11, the annular seal 22 is mounted in the mounting cavity 23 and is located between the shell 10 and the mounting shell 21, and the straight line L where the connecting line between any point on one end of the hole wall of each sound-permeable hole 24 and any point on the other end does not pass through the sound pickup hole 11.

[0032] In this way, the microphone of the present invention provides a waterproof and sound-permeable component 2 including a mounting shell 21, an annular seal 22 and a waterproof and sound-permeable membrane on the microphone body 1, and optimizes the position layout of the sound-permeable hole 24, thereby ensuring that the microphone can reduce noise and improve the purity of sound collection while being waterproof, thereby improving the waterproof performance and sound collection quality of the microphone, ensuring that only pure sound signals are transmitted to electronic components for processing, while moisture and dust are effectively blocked, and is suitable for various outdoor environments, especially in vehicle applications, and can effectively resist interference from external factors such as rain and dust, solving the problem in the prior art that microphones on cars are easily affected by external noise and have poor waterproofness, ensuring long-term stable operation of the vehicle, and improving the user experience and product reliability of the vehicle, especially for those vehicles that often need to operate in harsh environments, such as military vehicles, expedition vehicles, or emergency rescue vehicles, etc., to ensure that they can still work normally at critical moments, which is of great significance for performing tasks and ensuring personnel safety.

[0033] Specifically, "the straight line L connecting any point on one end of the hole wall of each sound-transmitting hole 24 with any point on the other end does not pass through the sound pickup hole 11" means that, in any sound-transmitting hole 24, the straight line L connecting any point on the end of the hole wall near the housing 10 and any point on the end of the hole wall far from the housing 10 does not pass through the sound pickup hole 11. This ensures that noise entering the mounting cavity 23 from any sound-transmitting hole 24 does not directly enter the sound pickup hole 11, but is instead blocked by the housing 10, thereby achieving a noise reduction effect. Furthermore, it is necessary that, in any sound-transmitting hole 24, the straight line L connecting the point on the end of the hole wall near the housing 10 that is closest to the centerline of the mounting cavity 23 and the point on the end of the hole wall far from the housing 10 that is farthest from the centerline of the mounting cavity 23 does not pass through the sound pickup hole 11.

[0034] like Figure 6 and Figure 7 As shown, the center line of the sound pickup hole 11 is collinear with the center line of the installation cavity 23, and multiple sound-transmitting holes 24 are evenly arranged 360° around the center line of the installation cavity 23; and / or the annular seal 22 is at least one of a foam ring and a rubber ring.

[0035] like Figure 6 and Figure 7 As shown, the mounting cavity 23 includes a first cavity 25 and a second cavity 26 connected to each other. The cross-sectional area of ​​the first cavity 25 is larger than the cross-sectional area of ​​the second cavity 26. The opening is located at the end of the first cavity 25 away from the second cavity 26. A portion of the housing 10 is installed in the first cavity 25. The annular seal 22 is located between the housing 10 and the bottom of the first cavity 25, forming an effective seal. This ensures that even when the microphone is subjected to force or displacement, the annular seal 22 can provide continuous waterproof and sealing effects, ensuring that the microphone can clearly capture sound in various motion states, which not only improves the reliability and durability of the microphone, but also ensures the ability of the microphone to record or transmit high-quality audio when moving with a car, etc.

[0036] Specifically, an annular groove for mounting the annular seal 22 is provided on the bottom surface of the first cavity 25 , and the height of the annular seal 22 is greater than the depth of the annular groove.

[0037] like Figures 1 to 7 As shown, the cross-sectional area of ​​the hole of the annular seal 22 is larger than the cross-sectional area of ​​the second cavity 26 .

[0038] Specifically, the outer shell 10 and the mounting shell 21 are detachably connected.

[0039] like Figures 1 to 7As shown, the housing 10 and the mounting shell 21 are connected via a plurality of snap structures 3 , and the plurality of snap structures 3 are arranged at intervals around the center line of the mounting cavity 23 .

[0040] like Figures 1 to 7 As shown, each snap-fit ​​structure 3 includes a snap-fit ​​protrusion 31 and a snap-fit ​​groove 32 that can be snapped together or separated. One of the snap-fit ​​protrusion 31 and the snap-fit ​​groove 32 is set on the shell 10, and the other of the snap-fit ​​protrusion 31 and the snap-fit ​​groove 32 is set on the mounting shell 21.

[0041] This simplifies the installation and removal process of the microphone and improves the maintenance efficiency of the microphone. Users can easily replace or repair the microphone to adapt to different usage scenarios or perform cleaning and maintenance without the need for professional tools or skills, reducing vehicle failures caused by microphone problems and playing a positive role in improving user experience and the overall operating efficiency of the vehicle.

[0042] Specifically, the engaging protrusion 31 is provided on the outer shell 10 , and the engaging groove 32 is provided on the mounting shell 21 .

[0043] like Figure 1 、 Figure 2 and Figure 6 As shown, a plurality of avoidance grooves 20 are provided on the outer side of the mounting shell 21, and the plurality of avoidance grooves 20 are provided in one-to-one correspondence with the plurality of snap structures 3, and each avoidance groove 20 is used to avoid the operation of the corresponding snap structure 3; a plurality of connection holes 27 are also provided on the outer side of the mounting shell 21, and the plurality of connection holes 27 are provided in one-to-one correspondence with the plurality of avoidance grooves 20, and each connection hole 27 is located on the bottom surface of the corresponding avoidance groove 20.

[0046] like Figure 8 As shown, the present invention further provides a vehicle, comprising a vehicle body 4 and a microphone assembly arranged on the vehicle body 4, wherein the microphone assembly is the above-mentioned microphone assembly.

[0047] In this way, the vehicle of the present invention solves the problem in the prior art that the microphone assembly on the car is composed of only a dual-microphone array, which can only distinguish the sounds in the directions of the left and right sides of the vehicle, but cannot distinguish the omnidirectional sounds around emergency vehicles (such as police cars, ambulances, fire trucks, etc.). It can provide drivers with a safer and more convenient driving experience, and enhance the product's market competitiveness and user satisfaction.

[0048] The vehicle of this utility model is not only suitable for traditional vehicles, but is particularly important for the voice interaction system of autonomous vehicles.
