Abstract

This invention provides a vehicle speaker, a door assembly, and a vehicle. The vehicle speaker includes: a top cover, comprising a cover plate and side plates extending circumferentially from the cover plate on the same side, the cover plate and side plates enclosing a receiving cavity, and the cover plate having a through-hole for mounting; a base, detachably connected to the top cover, the base forming a sound-absorbing cavity communicating with the receiving cavity; and a speaker, passing through the mounting hole and fixedly connected to the cover plate, with the speaker diaphragm exposed above the mounting hole. By using this invention, the connection between the base and the top cover allows the sound-absorbing cavity of the base to communicate with the receiving cavity of the top cover. The portion of the speaker other than its diaphragm is positioned within the space enclosed by the base and the top cover. This ensures that sound waves emitted by the speaker towards the base, i.e., towards the door sheet metal, are intercepted by the base within the sound-absorbing cavity, preventing direct propagation to the door sheet metal. This avoids excessive vibration of the door sheet metal, reduces the impact of door sheet metal vibration on sound quality, and improves the overall listening experience for passengers.

Description

Technical Field

[0001] This invention relates to the field of vehicle audio technology, specifically to a vehicle speaker, a door assembly, and a vehicle. Background Technology

[0002] With the development of car audio technology, users have increasingly higher requirements for car audio systems, especially in terms of bass performance. In traditional car audio systems, the subwoofers are directly mounted on the four door panels using a mounting structure. When the speakers are working, the airflow generated in the rear cavity directly impacts the door sheet metal, causing it to vibrate and resulting in sound quality degradation, affecting the overall listening experience. This is especially true at higher speeds (such as on highways) when the vibration is stronger, significantly reducing the bass performance. Summary of the Invention

[0003] In view of this, the present invention provides a vehicle speaker, a door assembly, and a vehicle to solve the above-mentioned technical problems.

[0004] The vehicle speaker provided by this invention includes:

[0005] The upper cover includes a cover plate and a side plate extending from the cover plate on the same side in the circumferential direction. The cover plate and the side plate enclose a receiving cavity, and the cover plate has a through mounting hole.

[0006] The base is detachably connected to the top cover, and the base forms a sound-absorbing cavity that communicates with the receiving cavity;

[0007] A loudspeaker, the loudspeaker passing through the mounting hole and fixedly connected to the cover plate, the diaphragm of the loudspeaker protruding from the mounting hole.

[0008] Optionally, a mounting plate is fixed circumferentially to one end of the base facing the upper cover, and the upper cover is detachably connected to the mounting plate.

[0009] Optionally, the vehicle speaker further includes:

[0010] A guide plate is disposed within the receiving cavity and fixedly connected to the cover plate. The first end of the guide plate extending in the receiving direction is fixedly connected to the side wall of the speaker within the receiving cavity, and the second end of the guide plate extending in the receiving direction is fixedly connected to the inner wall of the side plate. The guide plate surrounds the speaker, forming a back cavity with the speaker and a guide channel with the side plate. The guide channel communicates with the back cavity. After the top cover is connected to the base, the guide plate abuts against the mounting plate, and the mounting plate covers the guide channel.

[0011] The cover plate has a sound outlet at its second end near the extending direction of the guide plate, and the sound outlet is located within the guide channel.

[0012] Optionally, the guide plate is provided with multiple arc-shaped corners in the extending direction.

[0013] Optionally, the side plate is at least partially parallel to the guide plate.

[0014] Optionally, a mounting groove is formed on the side surface of the cover plate facing away from the base, and the mounting hole is opened through the bottom of the mounting groove. The speaker is fixedly connected to the bottom of the mounting groove circumferentially to the mounting hole.

[0015] Optionally, the speaker frame is circumferentially fixed with an abutment plate, the abutment plate surrounds the diaphragm, and after the speaker is fixed to the mounting groove, the abutment plate abuts against the circumferential inner wall of the mounting groove.

[0016] Optionally, the mounting plate has a through-hole.

[0017] The present invention also provides a vehicle door assembly, including a vehicle door, and further including the vehicle speaker as described in any of the above claims, wherein the vehicle speaker is mounted to the vehicle door.

[0018] The present invention also provides a vehicle including the door assembly described above.

[0019] The technical solutions provided by this invention have at least the following beneficial effects compared with the prior art:

[0020] The present invention utilizes a vehicle speaker, a door assembly, and a vehicle. By connecting the base and the top cover, the sound-absorbing cavity of the base is connected to the receiving cavity of the top cover. The part of the speaker other than the diaphragm is placed within the space enclosed by the base and the top cover. This allows the sound waves emitted by the speaker towards the base, i.e. towards the door sheet metal, to be intercepted by the base within the sound-absorbing cavity, preventing them from directly propagating to the door sheet metal. This avoids excessive vibration of the door sheet metal, reduces the impact of door sheet metal vibration on sound quality, and improves the overall listening experience for passengers.

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0031] Figure 1 This is an exploded view of a vehicle-mounted speaker according to an embodiment of the present invention; Figure 2 for Figure 1 A magnified view of point A on the car speaker shown; Figure 3 for Figure 1 The diagram shows the assembly of the car speaker. Figure 4 for Figure 3 The image shows a top view of the car speaker. Figures 1-4 As shown, the car speaker includes a top cover 1, a base 2, and a speaker 3. The top cover 1 includes a cover plate 11 and a side plate 12 extending from the same side of the cover plate 11 in the circumferential direction. The cover plate 11 and the side plate 12 enclose a receiving cavity, and the cover plate 11 has a through mounting hole 13. The base 2 is detachably connected to the top cover 1. The base 2 forms a sound-absorbing cavity 21, which communicates with the receiving cavity. The speaker 3 passes through the mounting hole 13 and is fixedly connected to the cover plate 11. The diaphragm 31 of the speaker 3 is exposed through the mounting hole 13.

[0032] In use, the speaker 3 is inserted into the receiving cavity of the upper cover 1 through the mounting hole 13, and the speaker 3 is fixedly connected to the cover plate 11, with the diaphragm 31 of the speaker 3 exposed outside the upper cover 1. The upper cover 1 with the speaker 3 fixed is connected to the base 2, so that the sound-absorbing cavity 21 of the base 2 is connected to the receiving cavity of the upper cover 1. That is, the speaker 3 is located in the sound-absorbing cavity 21 and the receiving cavity. The base 2 is installed to the car door, with the diaphragm 31 of the speaker 3 facing the inside of the car. When the diaphragm 31 vibrates and causes the speaker 3 to produce sound, the sound waves emitted towards the back of the speaker 3, that is, towards the base 2, are intercepted by the base 2 in the sound-absorbing cavity 21, so that the sound waves cannot be directly transmitted to the car door sheet metal, avoiding excessive vibration of the car door sheet metal, which would affect the sound quality of the speaker 3.

[0033] The in-vehicle speaker of this invention is connected to the upper cover 1 via the base 2, so that the sound absorption cavity 21 of the base 2 is connected to the receiving cavity of the upper cover 1. The part of the speaker 3 other than the diaphragm 31 is set in the space enclosed by the base 2 and the upper cover 1, so that the sound waves emitted by the speaker 3 toward the base 2, that is, toward the door sheet metal, are intercepted by the base 2 in the sound absorption cavity 21 and cannot be directly transmitted to the door sheet metal, thus avoiding excessive vibration of the door sheet metal, reducing the impact of door sheet metal vibration on sound quality, and improving the overall listening experience of passengers.

[0034] like Figures 1-4 As shown, in this embodiment, the upper cover 1 includes a horizontally arranged cover plate 11 and a side plate 12 extending downwards almost vertically from the cover plate 11 in the circumferential direction. A mounting hole 13 is formed through the center of the cover plate 11. The upper surface of the base 2 is recessed downwards to form a sound-absorbing cavity 21. The base 2 matches the shape and size of the upper cover 1, allowing for a detachable connection, for example, by means of bolts. The speaker 3 is configured as a woofer, such as... Figure 2 As shown, it includes a magnet 34 at the bottom, a frame 32 fixed to the magnet 34, a centering support 33 connected inside the frame 32, and a diaphragm 31 connected to the upper end of the centering support 33. The side of the frame 32 near the diaphragm 31 is connected to the cover plate 11. The speaker 3 is a mature existing technology, and its specific structure and working principle will not be described in detail here. Figure 1 , Figure 3As shown, the speaker 3 is inserted from top to bottom into the mounting hole 13 on the cover plate 11, keeping the diaphragm 31 exposed, and the speaker 3 is fixedly connected to the cover plate 11. The speaker 3 matches the size of the receiving cavity and the sound-absorbing cavity 21. After the upper cover 1 is connected to the base 2, at least a part of the speaker 3 is located in the sound-absorbing cavity 21 of the base 2, and the end of the speaker 3 away from the diaphragm 31 is kept at a certain distance from the bottom of the base 2. Since the car speaker is installed on the car door, in the prior art, when the car speaker plays sound, the sound waves from the back, that is, the sound waves facing the car door, may resonate with the outside of the car door within a certain frequency range, causing the car door to vibrate, resulting in damage to the speaker's sound quality. At the same time, it causes fatigue of the car door structure and reduces its service life. By setting the base 2 and setting the sound-absorbing cavity 21 on the base 2 to accommodate the back part of the speaker 3, the sound waves from the back of the speaker 3 can be intercepted, preventing them from resonating with the car door structure after being emitted. This improves the sound quality while protecting the car door structure. Depending on the actual application, the specific shape and size of the top cover 1 and the base 2 can be adjusted to match the changes in the specifications of the speaker 3.

[0035] Optionally, a mounting plate 4 is fixed circumferentially to the end of the base 2 facing the upper cover 1, and the upper cover 1 and the mounting plate 4 are detachably connected. This arrangement increases the contact area between the upper cover 1 and the mounting plate 4, which helps to improve the convenience and efficiency of connecting the upper cover 1 and the base 2.

[0036] like Figure 1 As shown, in this embodiment, an irregularly shaped mounting plate 4 is horizontally fixed to the upper end of the base 2, and the upper cover 1 is detachably connected to the mounting plate 4. The specific shape and size of the mounting plate 4 can be adjusted according to the actual application.

[0037] Figure 5 for Figure 1 The top view of the car speaker shown; Figure 6 for Figure 5 The top view of the cover is shown. Figure 5 and Figure 6 As shown, optionally, the vehicle speaker also includes a guide plate 5, which is disposed in the receiving cavity and fixedly connected to the cover plate 11. The first end of the guide plate 5 extending in the receiving cavity is fixedly connected to the side wall of the speaker 3 in the receiving cavity, and the second end of the guide plate 5 extending in the receiving cavity is fixedly connected to the inner wall of the side plate 12. The guide plate 5 surrounds the speaker 3, forming a back cavity 7 with the speaker 3 and a guide channel 6 with the side plate 12. The guide channel 6 connects to the back cavity 7. After the top cover 1 is connected to the base 2, the guide plate 5 abuts against the mounting plate 4, and the mounting plate 4 covers the guide channel 6. The cover plate 11 has a through-hole 14 at the second end near the extending direction of the guide plate 5, and the through-hole 14 is located in the guide channel 6.

[0038] When the speaker 3 emits sound, the sound waves from the back of the speaker 3, i.e., the sound waves generated by the vibration of the diaphragm 31 and directed towards the base 2, directly enter the back cavity 7. The back cavity 7 can buffer the relatively strong sound waves emitted directly from the back of the speaker 3, preventing them from interfering with the sound emitted from the front of the speaker 3, i.e., the sound generated by the vibration of the diaphragm 31 and directed towards the outside of the speaker enclosure. After buffering, a portion of the sound waves enters the guide channel 6 through the connection between the back cavity 7 and the guide channel 6, and is emitted from the outlet 14 at the end point after passing through the guide channel 6, thus superimposing with the sound emitted from the front of the speaker 3. This structure collects the sound waves emitted from the back of the speaker 3 through the guide plate 5 and the guide channel 6, allowing them to resonate and superimpose with the sound waves from the front of the speaker 3. In particular, it can enhance the bass performance and depth, thereby significantly improving the bass effect. In addition, some of the airflow in the cavity enclosed by the top cover 1 and the base 2 can be discharged, thereby reducing the vibration of the base 2. In addition, the guide channel 6 can reduce the impact of rear sound waves on front sound, while optimizing and limiting the propagation path of sound waves inside the top cover 1 and base 2, avoiding random reflection of sound waves that cause mutual interference and influence between sound waves, effectively improving the purity of low frequencies, as well as the clarity and separation of its sound quality, and enhancing the user experience.

[0039] like Figure 5 and Figure 6 As shown, in this embodiment, the guide plate 5 is perpendicular to the cover plate 11, and its end face facing the cover plate 11 is fixedly connected to the cover plate 11. The first end of the guide plate 5 extending in the direction of extension, that is, the lower end of the guide plate 5 in the figure, is fixedly connected to the lower side wall of the speaker 3 in the receiving cavity. The second end of the guide plate 5 extending in the direction of extension, that is, the left end of the guide plate 5 in the figure, is fixedly connected to the inner wall of the side plate 12 of the upper cover 1. The guide plate 5 surrounds the speaker 3 and leaves an outlet below the speaker 3, covering approximately three-quarters of the circumference of the speaker 3. The guide plate 5, the circumference of the speaker 3, and the cover plate 11 together enclose the back cavity 7. The guide plate 5, the side plate 12, and the cover plate 11 together enclose the guide channel 6. The guide channel 6 and the back cavity 7 communicate at the outlet left by the guide plate 5 surrounding the speaker 3. Figure 3 and Figure 5As shown, after the upper cover 1 is connected to the base 2, the guide plate 5 abuts against the mounting plate 4 around the base 2, and the mounting plate 4 covers the guide channel 6, so that the sound waves can be smoothly propagated through the back cavity 7 to the guide channel 6, and can be correctly propagated in the guide channel 6 and emitted from the sound outlet 14. According to the actual application, the specific extension length, extension shape, and the specific fixing position of the guide plate 5 to the speaker 3 and the inner wall of the side plate 12, as well as the range of the guide plate 5 around the speaker 3, can be appropriately adjusted. As long as the sound waves emitted by the diaphragm 31 of the speaker 3 vibrating towards the base 2 can be buffered by the back cavity 7, and after buffering, enter the guide channel 6 covered by the mounting plate 4, and after propagating along the guide channel 6, finally be emitted from the sound outlet 14 at the end of the guide channel 6, and superimposed with the sound waves of the speaker 3 propagating away from the base 2.

[0040] Optionally, the guide plate 5 has multiple arc-shaped corners in its extension direction. This arrangement can extend the length of the guide channel 6 within the limited space of the accommodating cavity, lengthening the propagation path of the sound waves. This reduces the speed of low-frequency sound waves, allowing the low frequencies to resonate better within the guide channel 6, increasing their perception and depth, and enhancing the bass effect.

[0041] like Figure 5 and Figure 6 As shown, in this embodiment, multiple arc-shaped corners are provided along the extension direction of the guide plate 5. Some face the direction of the speaker 3, while others face away from the direction of the speaker 3. The curvature of each arc-shaped corner is different. In the figure, the arc-shaped corner with the greatest curvature appears near the sound outlet 14. The number of arc-shaped corners and the specific curvature can be adjusted appropriately according to the actual application.

[0042] Optionally, the side plate 12 and the guide plate 5 are at least partially parallel. When the side plate 12 and the guide plate 5 are parallel, the width of the guide channel 6 remains unchanged, and the uniform width of the guide channel 6 can avoid chaotic sound wave reflections.

[0043] like Figure 5 and Figure 6 As shown, in this embodiment, the side plate 12 of the upper cover 1 is provided with multiple arc-shaped surfaces corresponding to the arc-shaped corners of the guide plate 5, so that the side plate 12 is parallel to the guide plate 5 over a larger range, so that the width of the guide channel 6 does not change abruptly and the distribution is more uniform. Figure 5 and Figure 6 Except for the vicinity of the two ends of the guide plate 5 in the extension direction, the guide plate 5 is almost parallel to the side plate 12 throughout the entire extension range of the guide plate 5.

[0044] Optionally, a mounting groove 15 is formed on the side of the cover plate 11 facing away from the base 2. A mounting hole 13 is formed through the bottom of the mounting groove 15, and the speaker 3 is fixedly connected to the bottom of the mounting groove 15 around the mounting hole 13. Installing the speaker 3 in the mounting groove 15 reduces the installation height of the speaker 3 and decreases the overall height of the vehicle speaker box.

[0045] like Figure 1 and Figure 3 As shown, in this embodiment, the center of the upper surface of the cover plate 11 is recessed towards the base 2 to form a square-section mounting groove 15. A circular mounting hole 13 is provided through the center of the bottom of the mounting groove 15. The speaker 3 passes through the mounting hole 13 and is fixedly connected to the bottom of the mounting groove 15. In this embodiment, multiple fixing holes 151 are uniformly provided around the circumference of the bottom of the mounting groove 15. After the end of the speaker 3 facing the base 2 passes through the fixing hole 151, part of the frame 32 of the speaker 3 overlaps the bottom of the mounting groove 15. Fasteners 9, such as screws, pass through the frame 32 of the speaker 3 and the fixing hole 151 at the bottom of the mounting groove 15, thereby connecting the speaker 3 to the upper cover 1 and facilitating disassembly and assembly.

[0046] Optionally, a stop plate 8 is circumferentially fixed to the frame 32 of the speaker 3, surrounding the diaphragm 31. After the speaker 3 is fixed to the mounting groove 15, the stop plate 8 abuts against the inner circumferential wall of the mounting groove 15. With this arrangement, after the frame 32 of the speaker 3 is connected to the cover plate 11, the stop plate 8 abuts against the inner wall of the mounting groove 15, which can effectively improve the stability of the installation. At the same time, it can reduce the vibration transmitted to the upper cover 1 when the speaker 3 emits sound, reduce the overall vibration of the speaker box, and reduce the impact on the car door or other mounting structures.

[0047] like Figures 1-3 As shown, in this embodiment, a ring of abutment plates 8 is fixed to the edge of the frame 32 of the speaker 3. The abutment plates 8 are vertically arranged and match the wall of the mounting groove 15. After the speaker 3 passes through the mounting hole 13 from top to bottom, part of the frame 32 of the speaker 3 overlaps the bottom of the mounting groove 15. At the same time, the abutment plates 8 on the circumference of the frame 32 abut against the inner circumference of the mounting groove 15. When the speaker 3 emits sound, the sound waves propagating towards the inner wall of the mounting groove 15 are first intercepted and buffered by the abutment plates 8 before continuing to be transmitted to the upper cover 1, thereby reducing the vibration of the upper cover 1.

[0048] Optionally, a connecting hole 41 is provided through the mounting plate 4. With this configuration, the connecting hole 41 can be used to connect and install the speaker to a car door or other structure using fasteners such as screws or bolts.

[0049] like Figure 1 , Figure 3 and Figure 4As shown, in this embodiment, after the upper cover 1 and the base 2 are connected and fixed, a portion of the mounting plate 4 extends beyond the cross-sectional area of ​​the upper cover 1 and the base 2, protruding from both, and a connecting hole 41 is formed through the protruding portion. The specific location and number of connecting holes 41 on the mounting plate 4 can be adjusted according to the actual application.

[0050] Figure 7 The graph shows the vibration amplitude of the car door. In the graph, the blue curve represents the vibration of the car door monitored after the car speaker in the prior art emits sound waves, with the vibration amplitude remaining at approximately 0.87. The red curve represents the vibration of the car door monitored after the car speaker in this application emits sound waves, with the vibration amplitude remaining at approximately 0.45. The test data shows that using the car speaker in this application reduces the vibration amplitude by approximately 50% compared to using the car speaker in the prior art, proving the application effect of the car speaker in this application.

[0051] The present invention also provides a door assembly, including a door and a vehicle speaker as described in any of the above embodiments, the vehicle speaker being installed in the door.

[0052] The door assembly of this invention connects the base 2 and the top cover 1, allowing the sound-absorbing cavity 21 of the base 2 to communicate with the receiving cavity of the top cover 1. The portion of the speaker 3 other than the diaphragm 31 is placed within the space enclosed by the base 2 and the top cover 1. This ensures that the sound waves emitted by the speaker 3 towards the base 2, i.e. towards the door sheet metal, are intercepted by the base 2 within the sound-absorbing cavity 21 and cannot directly propagate to the door sheet metal. This prevents excessive vibration of the door sheet metal, reduces the impact of door sheet metal vibration on sound quality, and improves the overall auditory experience for passengers.

[0053] When installing the car speaker into the car door, the top cover 1 should face the inside of the car, and the base 2 should face the sheet metal side of the car door. Bolts, screws, etc. can be used to connect the base 2 to the car door.

[0054] The present invention also provides a vehicle including the door assembly described in the above embodiments.

[0055] In the vehicle using this invention, the base 2 is connected to the top cover 1, so that the sound-absorbing cavity 21 of the base 2 is connected to the receiving cavity of the top cover 1. The part of the speaker 3 other than the diaphragm 31 is set in the space enclosed by the base 2 and the top cover 1, so that the sound waves emitted by the speaker 3 towards the base 2, that is, towards the door sheet metal, are intercepted by the base 2 in the sound-absorbing cavity 21 and cannot be directly transmitted to the door sheet metal. This avoids excessive vibration of the door sheet metal, reduces the impact of door sheet metal vibration on sound quality, and improves the overall listening experience of passengers.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
