[0049] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0050] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0051] 1 to 3 , this embodiment provides a roof structure, including a roof body 1 , a microphone 2 , and a roof frame 3 connected to a vehicle.

[0052] Microphone 2 is connected to ceiling frame 3, and microphone 2 and ceiling frame 3 are located on one side of ceiling body 1. Ceiling body 1 includes at least a base material layer 11 and a fabric layer 12 connected to base material layer 11. Base material layer 11 is located between fabric layer 12 and microphone 2. Base material layer 11 is provided with a sound-transmitting hole 111 at a position corresponding to the sound pickup hole 21 of microphone 2, which communicates with sound pickup hole 21.

[0053] In a specific implementation, the ceiling body 1 can be bonded or clipped onto the vehicle's ceiling frame 3, with the microphone 2 and the ceiling frame 3 located on one side of the ceiling body 1. This side can be considered the side of the ceiling body 1 facing away from the vehicle's interior cockpit. Specifically, the ceiling body 1 can include an inner surface and an outer surface that are disposed opposite each other along the thickness of the ceiling body 1. The outer surface can be considered the side facing the vehicle's interior cockpit, i.e., the outer surface is the exterior surface of the ceiling body 1 visible to passengers when they look up. The inner surface can be considered the side facing away from the vehicle's interior cockpit, i.e., the side that users cannot see when they look up. The microphone 2 can be mounted on the inner surface of the ceiling body 1.

[0054] Specifically, when the ceiling body 1 is configured to include a substrate layer 11 and a fabric layer 12, the side of the fabric layer 12 facing away from the substrate layer 11 faces the interior of the vehicle's cockpit and forms an exterior surface visible to the user, while the substrate layer 1 is obscured by the fabric layer 12 and cannot be seen by the user. Since the substrate layer 11 is located between the fabric layer 12 and the microphone 2, that is, the microphone 2 is located on the side of the substrate layer 11 away from the fabric layer 12, both the microphone 2 and the substrate layer 11 are obscured by the fabric layer 12, thereby achieving a concealed installation of the microphone 2. This ensures the integrity and aesthetics of the entire exterior surface of the ceiling body 1 without affecting the overall design of the ceiling body 1.

[0055] That is to say, the microphone 2, the base material layer 11 and the fabric layer 12 are arranged in sequence along the direction from the outer surface of the entire roof structure (the side surface facing the outside of the vehicle) to the inner surface of the roof structure (the side surface facing the cockpit or passenger compartment inside the vehicle). Therefore, when the user looks up, he can only see the fabric layer 12 but cannot see the microphone 2 and the base material layer 11.

[0056] When the microphone 2 is concealedly installed on the side of the base material layer 11 away from the fabric layer 12, the material properties of the fabric layer 12 make it sound-transparent, that is, the fabric layer 12 itself has small holes for sound to pass through. Therefore, it is only necessary to set a sound-transparent hole 111 connected to the sound pickup hole 21 at a position corresponding to the sound pickup hole 21 of the microphone 2 on the base material layer 11, so that the sound inside the car can pass through the fabric layer 12 and the sound-transparent hole 111 and enter the microphone 2, so as to be recognized and processed by the chip on the circuit board inside the microphone 2 to realize the microphone function. The specific sound pickup function of the microphone 2 can refer to the description in the relevant technology and will not be repeated here.

[0057] For example, the fabric layer 12 can be made of fabric, woven fabric, etc. The base material layer 11 can be made of plastic or alloy, etc.

[0058] Illustratively, the microphone 2 in this embodiment can be an integrated microphone, that is, the entire microphone 2 is a complete integrated structure when it leaves the factory. It is only necessary to connect the integrated microphone to the ceiling frame 3 and make the integrated microphone located on the side of the base material layer 11 away from the fabric layer 12. This not only realizes the hidden installation of the microphone, but also effectively avoids the problem of relative vibration caused by setting the microphone 2 as a split type in the related technology. Therefore, the vibration isolation effect of the microphone 2 in this embodiment is better.

[0059] Alternatively, in other implementations, the microphone 2 can be provided as two separate parts, which can be assembled by snapping or screwing the two separate parts together and then connected to the ceiling frame 3 so that the assembled microphone is located on the side of the base material layer 11 away from the fabric layer 12, thereby achieving a hidden installation of the microphone.

[0060] The ceiling structure of this embodiment includes a ceiling body 1 and a microphone 2. The ceiling body 1 is arranged on a roof frame 3 of a vehicle. The microphone 2 is connected to the ceiling frame 3, and the microphone 2 and the ceiling frame 3 are located on one side of the ceiling body 1. The ceiling body 1 includes at least a base material layer 11 and a fabric layer 12 connected to the base material layer 11. The base material layer 11 is located between the fabric layer 12 and the microphone 2, and a sound-permeable hole 111 connected to the sound pickup hole 21 of the microphone 2 is provided at a position corresponding to the microphone 2 on the base material layer 11. That is to say, the ceiling structure of this embodiment, by arranging the microphone 2 on the side of the base material layer 11 of the ceiling body 1 away from the fabric layer 12, and the fabric layer 12 itself is sound-permeable, so that the sound inside the car can pass through the fabric layer 12 and then enter the sound pickup hole 21 of the microphone 2 through the sound-permeable hole 111 of the base material layer 11, so that the microphone 2 can perform sound recognition processing, thereby realizing the hidden installation of the microphone 2 in the ceiling body 1, thereby ensuring the integrity of the entire appearance of the roof without affecting the shape design of the ceiling body 1.

[0061] 2 to 4 , in some embodiments, the microphone 2 includes a microphone body 22 and a dustproof mesh structure 23 . The dustproof mesh structure 23 is pressed between the microphone body 22 and the substrate layer 11 , and the sound pickup hole 21 is provided on the microphone body 22 .

[0062] In specific implementation, in this embodiment, the dustproof net structure 23 is crimped between the microphone body 22 and the base material layer 11, so that the dustproof net structure 23 can be effectively compressed by the crimping effect between the microphone body 22 and the base material layer 11, so that the thickness of the dustproof net structure 23 in the direction from the microphone 2 to the base material layer 11 can be thinned to a certain extent, and then the distance between the sound pickup hole 21 set on the microphone body 22 and the outer surface of the ceiling body 1 (that is, the side of the ceiling body 1 facing the cockpit in the car) can be effectively shortened to avoid the problem of decreased acoustic performance caused by reflection of sound during propagation due to the excessive length of the sound pickup hole 21 and the outer surface of the ceiling body 1.

[0063] Therefore, in this embodiment, by thinning the thickness of the dustproof net structure 23, the user's experience of voice recognition of the vehicle's microphone 2 can be effectively improved, and the pickup rate of the microphone 2 can be effectively improved, thereby effectively improving the comfort experience of riding.

[0064] 4 , in some embodiments, the dustproof net structure 23 includes a compressible foam layer and a tuning paper layer connected to the foam layer; the foam layer and the tuning paper layer are arranged sequentially along the direction from the microphone body 22 to the substrate layer 11 .

[0065] In specific implementation, the foam layer and the tuning paper layer are crimped between the microphone body 22 and the base material layer 11. The foam layer is effectively compressed through the crimping action between the microphone body 22 and the base material layer 11, so that the thickness of the dustproof net structure 23 can be thinned to a certain extent, and then the distance between the sound pickup hole 21 set on the microphone body 22 and the outer surface of the ceiling body 1 (that is, the side of the ceiling body 1 facing the cockpit in the car) can be effectively shortened to avoid the problem of decreased acoustic performance caused by reflection of sound during propagation due to the excessive length of the sound pickup hole 21 and the outer surface of the ceiling body 1.

[0066] In addition, in addition to allowing the compressible foam layer to be effectively compressed to achieve the effect of thinning the dustproof net structure 23, the pressing action between the microphone body 22 and the base material layer 11 can also compress the tuning paper layer to a certain extent, so that the thickness of the tuning paper layer can also be thinned to a certain extent, and then the thinning operation of the dustproof net structure 23 can be more effectively achieved to improve the acoustic performance.

[0067] For example, the foam layer and the tuning paper layer can be fixedly connected by adhesive. For example, the fabric layer 12 and the base material layer 11 can be bonded together using adhesive to achieve a reliable connection between the two. For example, the base material layer 11 and the microphone 2 can also be bonded together using adhesive to achieve a reliable connection between the two.

[0068] In a specific implementation, the microphone 2 can be connected to the ceiling frame 3 by snapping. In addition, in addition to being bonded to the base material layer 11, the microphone 2 can also be snap-connected to the ceiling frame 3, thereby making the installation of the microphone 2 more stable and reliable.

[0069] Specifically, a first clamping portion can be provided on the microphone 2, and a second clamping portion can be provided on the ceiling frame 3 at a position corresponding to the first clamping portion. The microphone 2 is fixed to the ceiling frame 3 through the clamping cooperation between the first clamping portion and the second clamping portion, so as to achieve reliable fixation of the microphone 2 on the ceiling frame 3.

[0070] Exemplarily, one of the first clamping portion and the second clamping portion can be a clamping notch 4, and the other of the first clamping portion and the second clamping portion can be provided with a clamping protrusion 5, and the microphone 2 is fixed on the ceiling frame 3 by the clamping cooperation between the clamping protrusion 5 and the clamping notch 4.

[0071] For example, a snap-fit ​​protrusion 5 may be provided on the microphone 2 , and a snap-fit ​​notch 4 may be provided on the ceiling frame 3 , or a snap-fit ​​notch 4 may be provided on the microphone 2 , and a snap-fit ​​protrusion 5 may be provided on the ceiling frame 3 .

[0072] For example, in order to improve the connection reliability between the microphone 2 and the ceiling frame 3, the snap-fitting protrusions 5 and the snap-fitting notches 4 can be multiple and arranged in one-to-one correspondence, so that the connection stability between the microphone 2 and the ceiling frame 3 can be further improved through the snap-fitting cooperation of multiple snap-fitting protrusions 5 and snap-fitting notches 4.

[0073] 1 and 5 , in some embodiments, the microphone 2 includes at least a front-row microphone 24 , a second-row microphone 25 , and a rear-row microphone 26 .

[0074] The front row microphone 24 is located in front of the front row seats of the vehicle; the second row microphone 25 is located in front of the second row seats of the vehicle and behind the front row seats; and the rear row microphone 26 is located in front of the rear row seats of the vehicle and behind the second row seats.

[0075] That is to say, in this embodiment, the microphone function is realized by arranging corresponding microphones 2 in front of the front seats, the second row of seats and the rear seats, so that the sounds emitted by passengers on different seats can be effectively extracted and recognized by the microphones 2 arranged at the corresponding positions, thereby improving the sound recognition experience.

[0076] In addition, for a passenger sitting in any seat in the car, the corresponding microphone 2 is located in front of the passenger sitting in that seat, so that the microphone 2 can pick up the sound emitted by the passenger sitting in the corresponding seat in a forward direction, thereby avoiding the problem that the microphone 2 is located behind the passenger in the related art, which causes the back-to-back pickup to affect the pickup effect.

[0077] Exemplarily, the front microphone 24 is used to recognize the sound emitted by the passenger sitting on the front seat, and the front microphone 24 is located in front of the passenger sitting on the front seat, so as to avoid back-facing sound pickup.

[0078] Exemplarily, the second row of microphones 25 is used to recognize the sounds made by passengers sitting on the second row of seats, and the second row of microphones 25 is located in front of the passengers sitting on the second row of seats, so as to avoid back-facing sound pickup.

[0079] Exemplarily, the rear microphone 26 is used to recognize the sounds made by passengers sitting on the rear seats, and the rear microphone 26 is located in front of the passengers sitting on the rear seats, so that back-facing sound pickup can be avoided.

[0080] It should be noted that the front referred to here is set based on the direction from the front of the vehicle to the rear of the vehicle, and the front of the vehicle is located in front of the rear of the vehicle.

[0081] 5 , in some embodiments, the front-row microphone 24 includes a first front-row microphone assembly 241 and a second front-row microphone assembly 242 that are sequentially disposed along the width direction of the vehicle.

[0082] The first front microphone assembly 241 includes a first front microphone 243 and a second front microphone 244 sequentially arranged along the width direction of the vehicle. The first front microphone 243 and the second front microphone 244 are both located in front of the main driver's seat of the front row seats.

[0083] The second front microphone assembly 242 includes a third front microphone 245 and a fourth front microphone 246 sequentially arranged along the width direction of the vehicle. The third front microphone 245 and the fourth front microphone 246 are both arranged in front of the passenger seat of the front row.

[0084] That is, the front row microphones 24 may specifically include four, namely a first front row microphone 243, a second front row microphone 244, a third front row microphone 245, and a fourth front row microphone 246. The first front row microphone 243, the second front row microphone 244, the third front row microphone 245, and the fourth front row microphone 246 are arranged sequentially along the width direction of the vehicle, for example, from the main driver's seat to the front passenger seat. The first front row microphone 243 and the second front row microphone 244 are located in front of the main driver's seat, thereby directly picking up the voice of the driver sitting in the main driver's seat. The third front row microphone 245 and the fourth front row microphone 246 are located in front of the front passenger seat, thereby directly picking up the voice of the passenger sitting in the front passenger seat.

[0085] 5 , in some embodiments, the first front microphone assembly 241 and the second front microphone assembly 242 are respectively located at both side edges of the ceiling body 1 along the width direction of the vehicle.

[0086] For example, the width direction of the vehicle is set to the direction from the main driver's seat to the front passenger seat, that is, the left to right direction of the vehicle. At this time, the first front microphone assembly 241 can be set close to the left edge of the ceiling body 1, and the second front microphone 244 can be set close to the right edge of the ceiling body 1, so as to effectively perform voice recognition on the driver sitting in the main driver's seat and the passenger sitting in the front passenger seat respectively, so as to avoid the first front microphone assembly 241 picking up the voice of the passenger sitting in the front passenger seat or the second front microphone assembly 242 picking up the voice of the driver sitting in the main driver's seat, so as to ensure the accuracy of voice recognition and thus improve the sound pickup effect.

[0087] 5 , in some embodiments, the two-row microphone 25 includes first and second-row microphone assemblies 251 and second and second-row microphone assemblies 252 that are spaced apart along the width direction of the vehicle.

[0088] The first and second rows of microphone assemblies 251 include first and second rows of microphones 253 and second and second rows of microphones 254 arranged in sequence along the length direction of the vehicle. The first and second rows of microphones 253 and second and second rows of microphones 254 are both arranged in front of part of the second row of seats located behind the main driver's seat of the vehicle.

[0089] The second-row microphone assembly 252 includes a third-row microphone 255 and a fourth-row microphone 256 arranged in sequence along the length direction of the vehicle. The third-row microphone 255 and the fourth-row microphone 256 are both arranged in front of part of the second row of seats behind the front passenger seat of the vehicle.

[0090] That is to say, the second row of microphones 25 can also specifically include four, namely the first second row of microphones 253, the second second row of microphones 254, the third second row of microphones 255 and the fourth second row of microphones 256, among which the first second row of microphones 253 and the second second row of microphones 254 are located in front of the left second row of seats of the vehicle, so as to pick up the sounds made by passengers sitting in the left second row of seats in the forward direction.

[0091] Among them, the third second-row microphone 255 and the fourth second-row microphone 256 are located in front of the second right-side row seats of the vehicle, so as to positively pick up the sounds made by passengers sitting on the second right-side row seats.

[0092] 5 , in some embodiments, the first and second rows of microphone assemblies 251 and the second and second rows of microphone assemblies 252 are respectively disposed at outer edges of the second row of seats in the width direction of the vehicle.

[0093] For example, assuming the vehicle's width is from the driver's seat to the passenger seat, that is, from left to right, the first second-row microphone assembly 251 can be positioned on the left outer edge of the second row of seats to effectively recognize the voices of passengers sitting in the left second row of seats and prevent the second second-row microphone assembly 252 from recognizing the voices of passengers sitting in the right second row of seats. Similarly, the second second-row microphone assembly 252 can be positioned on the right outer edge of the second row of seats to effectively recognize the voices of passengers sitting in the right second row of seats and prevent the second second-row microphone assembly 252 from recognizing the voices of passengers sitting in the left second row of seats, thereby improving voice pickup accuracy.

[0094] 5 , in some embodiments, the rear-row microphone 26 includes a first rear-row microphone assembly 261 and a second rear-row microphone assembly 262 that are sequentially disposed along the width direction of the vehicle.
