Description

Car audio system

[0001] This application claims priority to Chinese patent application CN202323505551.7, filed on December 21, 2023, with the invention name “Vehicle-mounted Audio System”. The entire contents of the above Chinese patent application are incorporated into this application by reference. Technical Field

[0002] The present invention relates to the technical field of vehicles, and in particular provides a vehicle-mounted audio system. Background Art

[0003] With the increasing popularity of cars, people have higher and higher requirements for the interior environment and riding experience of cars. To this end, major automobile manufacturers have invested a lot of research and development efforts in car seats, center consoles, audio systems and other interior configurations, striving for perfection, improving the comfort of their products and meeting the personalized needs of users.

[0004] Take the audio system, for example. Currently, the distances between the speakers and the passengers are often different, resulting in the left and right channels not reaching the passengers' ears simultaneously, leading to a poor listening experience. In particular, when the speaker's diffusion angle and power are insufficient, there can even be a sudden loss of sound due to a lack of coherence.

[0005] Accordingly, this field requires a new technical solution to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve the above technical problems, that is, to solve the problems of poor listening quality and even sudden loss of sound in the prior art sound system.

[0007] The present invention provides a vehicle-mounted audio system, which is arranged in a vehicle. The vehicle-mounted audio system includes a first speaker assembly, a second speaker assembly and a third speaker assembly. When viewed along the direction of travel of the vehicle, the second speaker assembly is arranged on the downstream side of the first speaker assembly, and the third speaker assembly is arranged on the downstream side of the second speaker assembly. The second speaker assembly includes a center speaker, and the center speaker is arranged on the center line of the vehicle, and the center line extends along the direction of travel of the vehicle.

[0008] When the above-mentioned technical solution is adopted, the sound field generated by the arrangement of three groups of speaker assemblies from front to back can cover the entire vehicle interior, meaning that passengers in any position in the vehicle can be covered by this sound field and hear the sound emitted by these speaker groups. The arrangement of the center speaker can supplement and enhance the sound effects of passengers in the vehicle, especially those sitting in the back seats, and can adjust the surround hearing of front passengers, making the overall sound performance in the vehicle more balanced and immersive. Through this arrangement, the sound can be evenly diffused throughout the vehicle, improving the coherence of the sound in the vehicle, and enhancing the clarity and power of the sound. Passengers in the front and back rows can hear the sound more clearly, making the sound in the entire vehicle more grand, natural, and three-dimensional, greatly enhancing the sound effects and improving the listening experience.

[0009] In an optional technical solution of the above-mentioned vehicle audio system, an armrest box is provided in the vehicle, the armrest box is located on the central line, and the center speaker is provided on the armrest box.

DETAILED DESCRIPTION

[0040] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0041] It should be noted that, in the description of the present invention, the terms “first” to “seventh” are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0042] Currently, in-vehicle audio systems suffer from issues such as poor listening quality, disjointed sound, and even sudden sound loss. To address this issue, the present invention provides an audio system comprising a first speaker assembly, a second speaker assembly, and a third speaker assembly positioned along the vehicle's travel direction. The center speaker of the second speaker assembly is positioned along the vehicle's centerline, ensuring even sound distribution throughout the vehicle. This improves sound continuity, clarity, and power, significantly enhancing the sound quality.

[0043] The following describes possible implementations of the vehicle audio system of the present invention with reference to Figure 1. It should be noted that Figure 1 shows a top view of the vehicle audio system installed in a vehicle, which only roughly illustrates the approximate positions of the speakers in the vehicle.

[0044] As shown in FIG1 , a vehicle is equipped with an in-vehicle audio system. The in-vehicle audio system includes a first speaker assembly, a second speaker assembly, and a third speaker assembly. The second speaker assembly is positioned downstream of the first speaker assembly, and the third speaker assembly is positioned downstream of the second speaker assembly, as viewed in the vehicle's direction of travel. Specifically, the first, second, and third speaker assemblies are positioned sequentially from front to back in the vehicle's direction of travel, with the first speaker assembly positioned approximately in front of the front seats, the second speaker assembly positioned approximately between the front and rear seats, and the third speaker assembly positioned approximately behind the rear seats. This provides multiple speaker assembly groups along the length of the vehicle. The sound field generated by these speaker assemblies covers the entire vehicle interior, meaning that passengers located anywhere in the vehicle are able to hear the sound field, allowing users to hear music, video, or other content played through these speaker groups. The second speaker assembly of the present invention includes a center speaker 40, which is positioned on the centerline of the vehicle. The centerline extends along the vehicle's direction of travel, meaning that the centerline extends approximately left and right in FIG1 . As shown in Figure 1, the second speaker assembly is positioned left-to-right between the first and third speaker assemblies. This means the center speaker 40 is positioned near the center of the vehicle. This center speaker 40 complements and enhances the sound experience for passengers, particularly those in the rear seats, and adjusts the surround sound experience for front-row passengers, resulting in a more balanced and immersive overall sound experience within the vehicle. This arrangement evenly distributes sound throughout the vehicle, improving its coherence, clarity, and power. This allows passengers in both the front and rear seats to hear the sound more clearly, making the sound throughout the vehicle more grand, natural, and three-dimensional, significantly enhancing the sound quality.

[0045] Continuing with Figure 1, the vehicle is equipped with an armrest box located on the centerline of the vehicle, near the rear seats. The center speaker 40 includes two first full-range speakers. These two first full-range speakers are located on the side of the armrest box facing the rear seats of the vehicle. When passengers sit in the rear seats, the two first full-range speakers face the rear passengers. The two first full-range speakers are roughly the same distance from the front seats, the rear seats, and the left and right sides of the vehicle. These two first full-range speakers can connect sound waves. When playing music or video, sound waves from various locations within the vehicle are relayed by the first full-range speakers. This solves the transmission problem caused by a long span, making the sound connection smoother and significantly reducing the gap in the middle. This allows sound to propagate smoothly within the vehicle, effectively improving the connection and continuity of the sound. Furthermore, it allows sounds from various sources to converge and be precisely localized in the rear seats, allowing passengers in the rear seats to experience a more three-dimensional sound experience. Furthermore, the center speaker 40, together with the first speaker assembly, creates an enveloping effect for passengers in the front seats, compensating for the limitations of the first speaker assembly in the front row. This complements and enhances the sound effects, creating a surround listening experience, especially in complex in-vehicle environments. This results in a more balanced sound performance within the vehicle, enhancing sound clarity and power.

[0046] It should be noted that the two first full-range speakers can be arranged side by side along the width direction of the vehicle on the side of the armrest box facing the rear seats, or can be arranged in sequence along the height direction of the vehicle, wherein the width direction of the vehicle is roughly the vertical direction in Figure 1, and the height direction of the vehicle is roughly the direction perpendicular to the paper in Figure 1. Obviously, the line between the two first full-range speakers and the bottom of the vehicle can also have an angle. Of course, the two first full-range speakers can also be set at other positions of the armrest box, for example, the upper surface of the armrest box, etc. Obviously, the two first full-range speakers can also be set at a position close to the center of the vehicle's ceiling. Without departing from the basic principles of the present application, those skilled in the art can flexibly select the specific setting position of the first full-range speakers according to the specific application scenario, as long as the two first full-range speakers can enhance the balance of the sound in the car and improve the connection and continuity of the sound.

[0047] It should be noted that the center speaker 40 may include only one first full-range speaker, or may include three, four, or a greater number of first full-range speakers. Without departing from the basic principles of the present application, those skilled in the art may flexibly select the number of first full-range speakers based on specific needs and cost control, as long as the first full-range speakers can enhance the balance, coherence, and continuity of the sound within the vehicle.

[0048] 1 , the first speaker assembly includes a first speaker group 10, a second speaker group 20, and a third speaker group 30. The first speaker group 10 is positioned near the left front door of the vehicle and includes a first tweeter 101, a first midrange speaker 102, and a first woofer 103. These three speakers are sequentially positioned along the vehicle's travel direction. For example, the first tweeter 101 is positioned on the left side of the dashboard near the left front door, and the first midrange speaker 102 and the first woofer 103 are positioned on the inside of the left front door. The second speaker group 20 is positioned near the right front door of the vehicle and includes a second tweeter 201, a second midrange speaker 202, and a second woofer 203. These three speakers are sequentially positioned along the vehicle's travel direction. For example, the second tweeter 201 is positioned on the right side of the dashboard near the right front door, and the second midrange speaker 202 and the second woofer 203 are positioned on the inside of the right front door. The first tweeter 101 and the second tweeter 201 are symmetrically arranged with each other, the first midrange speaker 102 and the second midrange speaker 202 are symmetrically arranged with each other, and the first woofer 103 and the second woofer 203 are symmetrically arranged with each other. In this way, when playing music or audio and video, the tweeters, midrange speakers and woofers arranged relatively on the left and right sides of the vehicle can well take into account the high-frequency part, the mid-frequency part and the low-frequency part of the sound, so that passengers sitting in the front seats can hear the sound clearly.

[0049] The third speaker group 30 is located on the vehicle's dashboard, along the centerline. It includes a third tweeter and a third midrange speaker. Figure 1 shows only the third tweeter; the third midrange speaker is not shown. These two speakers are roughly equidistant from the two front seats. This arrangement of the third speaker group 30 balances the sound field across the two front seats, allowing passengers in both seats to hear the sound more clearly. Furthermore, because the third speaker group 30 and the center speaker 40 are positioned on the same line, both located along the vehicle's centerline, their coordinated operation diffuses music and sound effects throughout the vehicle, resulting in a more balanced sound experience.

[0050] In this way, by symmetrically arranging the tweeters, mid-range speakers and woofers of the first speaker group 10 and the second speaker group 20, arranging the tweeters and mid-range speakers of the third speaker group 30, and arranging the third speaker group 30 on the center line, the high-frequency, mid-frequency and low-frequency parts of the sound can be better taken into account. At the same time, the sound can be made smoother through the relay of the third speaker group 30, and the sound can be surrounded by the passengers sitting in the front seats, so that the passengers have a better sound experience.

[0051] It should be noted that the first tweeter 101 can also be positioned on the vehicle's A-pillar, or in the front triangular window of the left front door glass, or near the left front door triangular window, etc. The second tweeter 201 can also be positioned on the vehicle's B-pillar, or in the front triangular window of the right front door glass, or near the right front door triangular window, etc. The first midrange speaker 102 and the first woofer 103 can be positioned anywhere inside the left front door, such as on the left front door armrest or below the window lift switch. The second midrange speaker 202 and the second woofer 203 can be positioned anywhere inside the right front door, such as on the right front door armrest or below the window lift switch. The third tweeter and the third midrange speaker can be positioned side by side on the dashboard along the width of the vehicle, or sequentially along the height of the vehicle. The line connecting the two full-range speakers can also form an angle with the vehicle floor. Without departing from the basic principles of the present application, those skilled in the art can flexibly select the specific setting positions of the first speaker group 10, the second speaker group 20 and the third speaker group 30 according to the specific application scenario, as long as they can take into account the high-frequency part, the mid-frequency part and the low-frequency part of the sound and improve the sound experience of the passengers.

[0052] It should be noted that the first speaker group 10 may also include only one or two of the first tweeter 101, the first midrange speaker 102, and the first woofer 103; the second speaker group 20 may also include only one or two of the second tweeter 201, the second midrange speaker 202, and the second woofer 203; and the third speaker group 30 may also include only one of the third tweeter and the third midrange speaker. Without departing from the basic principles of the present application, those skilled in the art may flexibly adjust the specific types and quantities of speakers included in the first speaker group 10, the second speaker group 20, and the third speaker group 30 according to specific application scenarios, as long as these speakers can achieve a balanced sound distribution in the front of the vehicle and passengers sitting in the front seats can clearly hear the sound.

[0053] It should be noted that the first speaker assembly may also only include the first speaker group 10 and the second speaker group 20 .

[0054] Continuing with FIG1 , the second speaker assembly includes a fourth speaker group 50 and a fifth speaker group 60. The fourth speaker group 50 is positioned near the left rear door of the vehicle and includes a fourth tweeter 501, a fourth midrange speaker 502, and a fourth woofer 503. These three speakers are positioned sequentially along the vehicle's travel direction. For example, the fourth tweeter 501, the fourth midrange speaker 502, and the fourth woofer 503 are positioned sequentially along the vehicle's travel direction, such as on the armrest of the left rear door or below the window lift switch. The fifth speaker group 60 is positioned near the right rear door of the vehicle and includes a fifth tweeter 601, a fifth midrange speaker 602, and a fifth woofer 603. These three speakers are positioned sequentially along the vehicle's travel direction, such as on the armrest of the right rear door or below the window lift switch. The fourth tweeter 501 is symmetrically positioned with the fifth tweeter 601, the fourth midrange speaker 502 is symmetrically positioned with the fourth midrange speaker 502, and the fourth woofer 503 is symmetrically positioned with the fourth woofer 503. This allows the tweeters, midrange speakers, and woofers on the left and right sides of the vehicle to effectively balance the high, mid, and low frequencies of the sound when playing music or video, ensuring clear audio for passengers in the rear seats. Furthermore, in conjunction with the center speaker 40, this enhances the smoothness and balance of the sound at the rear of the vehicle, allowing passengers in the rear seats to experience a more three-dimensional sound experience.

[0055] In this way, the symmetrical arrangement of the tweeters, midrange speakers and woofers of the fourth speaker group 50 and the fifth speaker group 60 can better take into account the high-frequency, mid-frequency and low-frequency parts of the sound, and through the cooperation of the two speaker groups and the center speaker 40, the sound can be smoother and surround the passengers sitting in the front seats, so that the passengers have a better sound experience.

[0056] It should be noted that the fourth speaker group 50 may also include only one or two of the fourth tweeter 501, the fourth midrange speaker 502, and the fourth woofer 503, and the fifth speaker group 60 may also include only one or two of the fifth tweeter 601, the fifth midrange speaker 602, and the fifth woofer 603. Without departing from the basic principles of the present application, those skilled in the art may flexibly adjust the specific types and quantities of speakers included in the fourth speaker group 50 and the fifth speaker group 60 according to specific application scenarios, as long as these speakers can achieve balanced sound distribution in the rear of the vehicle and passengers sitting in the front seats can clearly hear the sound.

[0057] Continuing with Figure 1 , the third speaker assembly includes a sixth speaker group 70 and a seventh speaker group 80. The sixth speaker group 70 is positioned on the left side of the vehicle's rear windshield and includes a sixth tweeter 701 and a sixth midrange speaker 702, arranged sequentially along the width of the vehicle. The seventh speaker group 80 is positioned on the right side of the vehicle's rear windshield and includes a seventh tweeter 801 and a seventh midrange speaker 802, arranged sequentially along the width of the vehicle. This arrangement provides additional tweeters and midrange speakers on the left and right sides behind rear passengers, further supplementing the high- and mid-frequency components of the sound at the rear of the vehicle, enhancing the sound quality in the rear seats and allowing rear passengers to hear more clearly. The center speaker 40, fourth speaker group 50, fifth speaker group 60, sixth speaker group 70, and seventh speaker group 80 form a roughly annular sound field that surrounds rear passengers, effectively enhancing the three-dimensionality of the sound and improving the sound quality.

[0058] It should be noted that the sixth tweeter 701 and the sixth midrange speaker 702 may also be arranged sequentially along the length of the vehicle, and the seventh tweeter 801 and the seventh midrange speaker 802 may also be arranged sequentially along the length of the vehicle. Without departing from the basic principles of this application, those skilled in the art may flexibly adjust the specific placement of the sixth tweeter 701, the sixth midrange speaker 702, the seventh tweeter 801, and the seventh midrange speaker 802 according to specific application scenarios, as long as these speakers can enable passengers sitting in the rear seats to clearly hear the sound and enhance the three-dimensional perception of the sound.

[0059] It should be noted that the sixth speaker group 70 may include only one of the sixth tweeter 701 and the sixth midrange speaker 702, and the seventh speaker group 80 may include only one of the seventh tweeter 801 and the seventh midrange speaker 802. Without departing from the basic principles of the present application, those skilled in the art may flexibly adjust the specific types and numbers of speakers included in the sixth speaker group 70 and the seventh speaker group 80 according to specific application scenarios, as long as these speakers can enable passengers sitting in the rear seats to hear the sound clearly and enhance the three-dimensional sense of the sound.

[0060] Continuing with Figure 1 , the vehicle-mounted sound system also includes a fourth speaker assembly, which includes a second full-range speaker 90, a third full-range speaker 100, a fourth full-range speaker 110, and a fifth full-range speaker 120. The second full-range speaker 90 is positioned near the left front side of the vehicle's ceiling, the third full-range speaker 100 is positioned near the right front side of the vehicle's ceiling, the fourth full-range speaker 110 is positioned near the left rear side of the vehicle's ceiling, and the fifth full-range speaker 120 is positioned near the right rear side of the vehicle's ceiling. In other words, these four full-range speakers form a circular sound field on the vehicle's ceiling, creating a circular sound field above the heads of all passengers. These four full-range speakers, together with the first, second, and third speaker assemblies, form a stereo system, providing a well-balanced stereo effect for all passengers in the vehicle. Furthermore, all four speakers are full-range speakers, capable of addressing all frequency components of the sound, thus providing a better sound experience.

[0061] It should be noted that the fourth speaker assembly may also include a smaller number of full-range speakers, such as three or two, or a larger number of full-range speakers, such as five or six. Obviously, the fourth speaker assembly may also be partially full-range speakers, partially tweeters or mid-range speakers or woofers, or may not include full-range speakers, and may be entirely composed of one, two or three of tweeters, mid-range speakers and woofers. Of course, the vehicle audio system may also not include the fourth speaker assembly. Without departing from the basic principles of this application, those skilled in the art may flexibly select the specific setting method of the fourth speaker assembly according to the specific application scenario, as long as it can provide passengers with a better sound experience.

[0062] Continuing with Figure 1 , the vehicle-mounted audio system also includes a fifth speaker assembly, comprising a first subwoofer 130 and a second subwoofer 140. The first subwoofer 130 is located in the footwell of the passenger seat, while the second subwoofer 140 is located in the trunk. This arrangement of two subwoofers, one in the front and one in the rear, effectively complements the low-frequency portion of the sound, giving it a richer sound, further propagation, and clarity. Combined with the tweeters, midrange speakers, and woofers in the other speaker assemblies, the sound throughout the vehicle is more powerful, natural, and three-dimensional.

[0063] It should be noted that the vehicle audio system may not include the fifth speaker assembly.

[0064] Based on the above-mentioned configuration, the first speaker assembly and the second speaker assembly are used to transmit sound from the left and right sides of the vehicle to the passengers sitting in the front and rear rows. The third speaker group 30 in the first speaker assembly and the center speaker 40 in the second speaker assembly can effectively connect the sound transmitted from the left and right sides of the vehicle, making the sound connection smooth and reducing the discontinuity in the middle. The center speaker 40 and the first speaker assembly can form an enveloping trend for the front passengers, creating a surround listening experience. The third speaker assembly and the second speaker assembly can form an enveloping trend for the rear passengers, enhancing the sound effect in the rear row and creating a surround listening experience.
