[0058] Reference Figures 1 to 5 The diagram shows a schematic of a speaker structure according to an embodiment of this application. The speaker structure is used to be installed on the dashboard 70 and may specifically include: a connecting part 10 and a speaker 20; the speaker 20 is disposed in the central control area of ​​the cockpit through the connecting part 10; the sound output end of the speaker 20 is disposed towards the driver's area of ​​the vehicle.

[0059] In this embodiment, the speaker structure is connected and installed through the connecting part 10, which makes the speaker structure have better installation stability and reliability. The sound output end of the speaker 20 is set towards the driver's area of ​​the vehicle, which allows the driver in front of the driver's area to obtain a better acoustic sound quality experience through the speaker 20. It increases the sense of spatial distance of the overall sound field in the cabin, reduces the interference and masking caused by other structures to the sound propagation to the driver, improves the ecological interactive experience of the overall acoustic sound quality and sound effect of the vehicle audio system, and also avoids the sound propagated by the speaker from directly entering the human ear, thus improving the driver's hearing experience and the vehicle audio effect.

[0060] It should be noted that, in this embodiment, the central control area of ​​the cockpit includes a center console and an instrument panel 70. The center console is a platform extending along the width of the vehicle in front of the steering wheel, and the instrument panel 70 is the structure on the left side of the center console. The instrument panel 70 is equipped with the speaker structure of this application. Furthermore, the instrument panel 70 may also be equipped with information display instruments such as a speedometer, odometer, and fuel gauge; alternatively, the instrument panel 70 may not have these information display instruments and may only be a panel structure. In this embodiment, in addition to the instrument panel 70, the center console may also be equipped with a multimedia system display screen and air conditioning vents, etc. This embodiment does not limit the specific type of center console configuration.

[0061] Specifically, in this embodiment, the connecting part 10 is used to install the speaker structure, and the speaker 20 is used to output audio from the speaker structure. For example, the connecting part 10 and the speaker 20 can be integrally molded, resulting in a high connection strength between them and reducing material waste and manufacturing processes. Alternatively, the connecting part 10 and the speaker 20 can be separate structures, connected by welding, bonding, or snap-fitting. This embodiment does not limit the specific connection method between the connecting part 10 and the speaker 20.

[0062] For example, in this embodiment, the speaker 20 can be positioned anywhere on the dashboard 70, such as the center, left, or right side of the dashboard 70, with the sound output direction of the speaker 20 facing the driver's area. For example, the speaker 20 can be positioned on the dashboard 70 directly opposite the steering wheel. Since the driver is directly opposite the steering wheel, the speaker 20 is positioned directly opposite the driver, thus providing the driver with a better acoustic experience from the audio emitted by the speaker 20.

[0063] In this embodiment, for example, the speaker 20 can be a surround sound structure to achieve an immersive sound experience and provide more natural and richer sound effects. Utilizing the three-way crossover system in the front doors of the vehicle, the speaker structure located in front of the driver in this embodiment can coordinate with other speakers in the vehicle (such as speakers located in the doors, speakers located on the right side of the center console facing the passenger area, and speakers located in the middle area of ​​the center console facing both the driver and passenger areas), matching sound effect algorithms to achieve a human-computer interaction scheme, enabling users to obtain a better acoustic sound quality experience and achieving multimodal and multi-ecosystem interaction.

[0064] In this embodiment of the application, the three-way crossover of the front doors of the vehicle refers to the use of three-way speakers and corresponding crossovers in the front door sound field of the vehicle audio system to perform frequency division processing on the audio signal, so that the high-frequency, mid-frequency and mid-low-frequency speakers are responsible for the sound signals of different frequencies, thereby improving the sound quality performance.

[0065] Specifically, the vehicle's front door may include a speaker assembly and a crossover. The speaker assembly includes a tweeter, a midrange speaker, and a mid-bass speaker. The tweeter typically outputs high-frequency sounds, the midrange speaker typically outputs mid-frequency sounds, and the mid-bass speaker typically outputs low-frequency and mid-low-frequency sounds. The crossover includes a high-pass filter, a low-pass filter, and a band-pass filter, used to divide the input audio signal into three frequency bands: high, mid, and low, and send them to the corresponding tweeter, midrange speaker, and mid-bass speaker respectively. This reduces poor output audio quality caused by insufficient speaker performance or overload distortion, resulting in more accurate sound reproduction.

[0066] Optionally, in this embodiment, the connecting portion 10 extends along a first direction, and the speaker portion 20 protrudes away from the connecting portion 10 along a second direction, with the first direction perpendicular to the second direction. This allows the connecting portion 10 to be positioned on the instrument panel 70 along the first direction, and the speaker portion 20 to protrude inwards towards the instrument panel 70 along the second direction, thus accommodating the speaker portion 20 within the instrument panel 70 and achieving a better aesthetic appearance. For example, the first direction can be parallel to the plane of the instrument panel 70, and the second direction can be perpendicular to the plane of the instrument panel 70. Furthermore, the first direction can also be at an angle to the plane of the instrument panel 70, such as 10°, 15°, or 20°, etc., depending on actual needs; this embodiment does not limit this.

[0067] Optionally, in this embodiment, the connecting portion 10 is provided with a first mounting hole 11, which is located on the outer periphery of the speaker portion 20. Thus, the first mounting hole 11 provides a mounting position for the connecting portion 10, allowing fasteners 60, such as screws, bolts, or studs, to pass through and be fixedly installed. For example, the shape of the first mounting hole 11 can be circular or elliptical, etc.; the specific shape of the first mounting hole 11 is not limited in this embodiment.

[0068] Optionally, in this embodiment, at least one first mounting hole 11 is distributed circumferentially around the speaker portion 20; the distance between two adjacent first mounting holes 11 along the width direction of the connecting portion 10 is smaller than the distance between two adjacent first mounting holes 11 along the length direction of the connecting portion 10. This ensures that the multiple first mounting holes 11 provide good mounting stability in both the length and width directions of the connecting portion 10, improving the installation reliability of the speaker structure and avoiding poor fixing of the connecting portion 10.

[0069] In this embodiment, the connecting portion 10 can be securely installed around the speaker portion 20 using multiple first mounting holes 11. For example, Figures 1 to 4 The diagram shows that there are four first mounting holes 11, which are located at the four corners of the rectangular connecting part 10. In addition, the number of first mounting holes 11 can be two, three, or five, etc. The specific number and location of the first mounting holes 11 are not limited in this application embodiment.

[0070] For example, in this embodiment, the distance between two adjacent first mounting holes 11 along the width direction of the connecting portion 10 can be any value between 43-45mm, such as 43mm, 44mm, or 45mm, etc. This ensures a suitable distance between two adjacent first mounting holes 11 along the width direction of the connecting portion 10, avoiding situations where a small distance results in poor fixing at both ends of the connecting portion 10 and easy lifting, or where a large distance results in poor fixing in the middle of the connecting portion 10 and easy bulging. Specifically, the distance between the centers of two adjacent first mounting holes 11 along the width direction of the connecting portion 10 can be 44±0.3mm. Furthermore, the distance between the centers of two adjacent first mounting holes 11 can also be 43.2mm, 43.5mm, 44.9mm, 44.5mm, etc., and this embodiment does not limit this.

[0071] In this embodiment, for example, the distance between two adjacent first mounting holes 11 along the length of the connecting portion 10 can be any value between 63-65mm, such as 63mm, 64mm, or 65mm. This ensures a suitable distance between adjacent first mounting holes 11 along the length of the connecting portion 10, avoiding situations where a small distance results in poor fixing at both ends of the connecting portion 10 and easy lifting, or where a large distance results in poor fixing in the middle of the connecting portion 10 and easy bulging. Specifically, the distance between the centers of two adjacent first mounting holes 11 along the length of the connecting portion 10 can be 64.29±0.3mm. Furthermore, the distance between the centers of two adjacent first mounting holes 11 can also be 63.2mm, 63.5mm, 64.5mm, 64.9mm, etc., and this embodiment does not limit this.

[0072] For example, in this embodiment, the diameter of the first mounting hole 11 can be any value between 5 and 5.5 mm, such as 5 mm, 5.2 mm, or 5.5 mm. This ensures that the first mounting hole 11 has a suitable diameter, avoiding the difficulty of installation due to a small diameter and preventing a reduction in the structural strength of the connection part 10 due to a large diameter. Specifically, the diameter of the first mounting hole 11 can be set to 5.25 ± 0.2 mm. Alternatively, the diameter can be set to 5 mm or 5.5 mm, etc. This embodiment does not limit the specific value of the diameter of the first mounting hole 11.

[0073] Optionally, in this embodiment, the connecting part 10 is provided with a positioning port 12, which is used for installing and positioning the connecting part 10. For example, the number of positioning ports 12 can be one, two, or three, etc., and can be set according to actual needs. In this embodiment, the specific number of positioning ports 12 is not limited. And / or, the length of the positioning port 12 is any value between 4.5-7mm, and the width of the positioning port 12 is any value between 4.5-6mm. In this way, when installing the speaker structure, the connecting part 10 can be installed and positioned by snapping the positioning port 12 on the connecting part 10 onto the corresponding positioning member 54 on the mounting bracket, which is simple, reliable, and convenient to operate. For example, the length of the positioning port 12 can be 4.5mm, 5mm, 6mm, or 7mm, etc., and the width of the positioning port 12 can be 4.5mm, 5mm, or 6mm, etc., to avoid the problem of its small size making it difficult to snap onto the positioning member 54, and also to avoid its large size reducing the structural strength of the connecting part 10. In this embodiment, the specific values ​​of the length and width of the positioning port 12 are not limited.

[0074] In this embodiment, optionally, taking two positioning ports 12 as an example, each positioning port 12 includes a first notch 13 and a second notch 14. The first notch 13 is located at the edge of the connecting portion 10 along its length direction, and the second notch 14 is located at the edge of the connecting portion 10 along its width direction. In this way, the first notch 13 and the second notch 14 simultaneously position the connecting portion 10 in both its length and width directions, further improving positioning reliability. Furthermore, placing the first notch 13 and the second notch 14 at the edges of the connecting portion 10 facilitates the engagement of the positioning member 54 on the mounting member 50, improving convenience. For example, the first notch 13 and the second notch 14 can be diagonally arranged, symmetrically arranged, etc. The specific positions of the first notch 13 and the second notch 14 are not limited in this embodiment.

[0075] For example, in this embodiment of the application, the first notch 13 is provided in the length direction of the connecting portion 10, and its length can be 6.79±0.2mm and its width can be 5.4±0.2mm. The second notch 14 is provided in the width direction of the connecting portion 10, and its length can be 5.17±0.2mm and its width can be 5±0.2mm, so that the first notch 13 and the second notch 14 achieve a good snap-fit ​​positioning effect, while taking into account the good structural strength of the connecting portion 10.

[0076] In this embodiment, for example, the distance between the first notch 13 and the nearest first mounting hole 11 in the length direction of the connecting portion 10 can be 8.45±0.2mm. This ensures a suitable distance between the first notch 13 and the nearest first mounting hole 11, avoiding a small distance affecting the structural strength of the connecting portion 10 in the length direction, and also avoiding a large distance making layout difficult. The distance between the second notch 14 and the nearest first mounting hole 11 in the width direction of the connecting portion 10 can be 9.45±0.2mm. This ensures a suitable distance between the second notch 14 and the nearest first mounting hole 11, avoiding a small distance affecting the structural strength of the connecting portion 10 in the width direction, and also avoiding a large distance making layout difficult.

[0077] Optionally, in this embodiment, in the first operating state, the sound pressure level (SPL) of the speaker 20 is any value between 81.5 and 83.5 dB; and / or, in the second operating state, the total harmonic distortion (THD) of the speaker 20 is less than or equal to 0.6%. For example, in the first operating state, such as when high-frequency sound signals need to be transmitted, ... Figure 6 As shown in the simulation test, when the operating frequency, or effective frequency range, of the speaker 20 is in the range of 200-20000Hz, the sensitivity of the speaker 20 can be in the range of 81.5-83.5dB. This gives the speaker 20 high sensitivity, enabling it to produce a higher sound pressure level under the same input power, providing a higher volume output, improving the overall efficiency of the system, enhancing the dynamic range, and providing a more natural and realistic listening experience.

[0078] For example, in the second operating state, such as when it is necessary to transmit intermediate frequency audio signals, low frequency audio signals, and low-mid frequency audio signals, as... Figure 7 As shown in the simulation test, when the speaker 20 operates at a frequency of 1-10kHz, which is also the effective frequency, its total harmonic distortion rate can be less than or equal to 0.6%. This results in fewer additional harmonic components generated by the speaker structure when playing audio, and the sound is closer to the original signal. This allows the speaker structure to provide a purer and more natural sound quality, with better high-frequency, mid-frequency and low-frequency performance, a wider dynamic range, more stable performance, and a longer service life, which can significantly improve the user's listening experience.

[0079] In this embodiment, the speaker structure can operate at any temperature between -40°C and 85°C, and can be stored at any temperature between -40°C and 95°C, exhibiting good cold and heat resistance. The speaker structure has an IP5K2 protection rating, where IP (Ingress Protection) indicates the protection level, 5 indicates a dustproof rating of 5, and K2 indicates a waterproof rating of K2, providing good dustproof capability and withstanding high-pressure water jets. It is suitable for outdoor and industrial environments, effectively preventing damage to the speaker structure from dust and high-pressure water. Furthermore, the speaker structure can operate at any voltage between 4.5V and 9V, and its rated resistance can be 4Ω, 5Ω, or 3Ω, etc.

[0080] Optionally, in this embodiment, the speaker structure includes a buffer 30 connected to the inner side of the connecting portion 10; and / or, the speaker structure includes a buffer ring 31 located on the outer side of the connecting portion 10 and wrapped around the outer periphery of the speaker portion 20; and / or, the speaker structure includes a connector 40 connected to the inner side of the connecting portion 10 and electrically connected to the speaker portion 20. Specifically, the inner side of the connecting portion 10 is the side closer to the interior of the instrument panel 70. In this way, the buffer 30 provides buffering for the connecting portion 10, achieving a better vibration damping effect. For example, the buffer 30 can be foam, and the buffer 30 has a clearance opening at a position opposite to the speaker portion 20 and the first mounting hole 11 and positioning port 12 to prevent interference. A buffer ring 31 is located on the outer side of the connecting portion 10, with the outer side of the connecting portion 10 facing away from the inner side. The buffer ring 31 is located at the circumferential edge of the speaker 20, improving the energy absorption effect of the front of the speaker 20 and providing better vibration damping. A connector 40 is provided on the inner side of the connecting portion 10 for connecting a power plug or interface, etc., to achieve the circuit connection of the speaker 20. Specifically, the power plug or interface can supply power to the speaker and receive electrical signals through wires, etc.

[0081] Specifically, in this embodiment, the inner side of the connecting portion 10 is located inside the instrument panel 70, and the outer side of the connecting portion 10 is disposed opposite to the inner side, located outside the instrument panel 70. When the speaker structure is mounted on the vehicle body, the inner side of the connecting portion 10 is not visible, while the outer side of the connecting portion 10 is exposed and visible. For example, such as... Figure 2 and Figure 4 One side of the connecting part 10 shown is the inner side of the connecting part 10, such as... Figure 1 and Figure 3 The side of the connecting part 10 shown is the outer side of the connecting part 10.

[0082] For example, in this embodiment, the buffer has a groove, and the speaker and connector are located in the groove. The shape of the groove is adapted to the shape of the speaker and connector, so that the buffer has a larger layout area and improves the vibration damping effect. For example, the shape of the groove portion corresponding to the connector can be approximately trapezoidal or other shapes. This embodiment does not limit the specific shape of the groove.

[0083] Optionally, in this embodiment, the speaker structure includes a reinforcing component located inside the connecting portion 10 and connected to both the connecting portion 10 and the speaker portion 20. The reinforcing component strengthens the connecting portion 10 and the speaker portion 20, thereby improving the overall structural stability of the speaker structure.

[0084] Optionally, in this embodiment, the reinforcement component includes a reinforcement ring 21, which is located inside the connecting portion 10 and wrapped around the outer periphery of the speaker portion 20. In this way, the connecting portion 10 and the speaker portion 20 are structurally reinforced by the reinforcement ring 21 located inside the connecting portion 10. Furthermore, the reinforcement ring 21 is arranged around the circumferential edge of the speaker portion 20, which can structurally reinforce all positions on the outer periphery of the speaker portion 20, thereby improving the connection reliability and stability of the speaker portion 20.

[0085] Optionally, in this embodiment, the reinforcing component includes a reinforcing plate 22 connected to the reinforcing ring 21, and the reinforcing plate 22 extends along the tangential direction of the reinforcing ring 21; and / or, the reinforcing component includes a reinforcing rib 23, and a bracket 15 is also provided on the inner side of the connecting plate, with the reinforcing rib 23 connecting the reinforcing ring 21 and the bracket 15. Thus, the reinforcing plate 22 is also located on the inner side of the connecting portion 10, and the reinforcing plate 22 is connected to the reinforcing ring 21, extending along the tangential direction or approximately the tangential direction of the reinforcing ring 21. This enhances the structural stability and reliability of the reinforcing ring 21 through the reinforcing plate 22, reduces the risk of deformation of the reinforcing ring, and further improves the structural reinforcement effect of the speaker 20. Furthermore, the reinforcing rib 23 strengthens the structure of the reinforcing ring 21, enhancing its structural stability and reliability, and further improving the structural reinforcement effect of the speaker 20.

[0086] For example, in this embodiment of the application, the bracket 15 is provided with a snap-fit ​​interface, one end of the reinforcing rib 23 is connected to the reinforcing ring 21, and the other end of the reinforcing rib 23 is snapped into the snap-fit ​​interface of the bracket 15, so as to achieve a relatively stable and reliable connection between the reinforcing rib 23, the reinforcing ring 21 and the bracket 15.

[0087] In this embodiment, for example, there can be two reinforcing plates 22, symmetrically distributed on both sides of the reinforcing ring 21, further improving the structural reinforcement effect of the speaker 20. Connecting wires can be wound around the inside of the reinforcing plates 22, which can protect the connecting wires. For example, the two reinforcing plates 22 can extend close to each other at an acute angle, making the reinforcing plate 22 structure more compact and thus providing a larger installation area for the buffer 30. For example, there can be two reinforcing ribs 23 and two brackets 15, symmetrically distributed. Furthermore, the number of reinforcing plates 22, reinforcing ribs 23, and brackets 15 can also be three or four, etc., depending on actual needs. This embodiment does not limit the number or distribution of these components.

[0088] Optionally, in this embodiment, the reinforcing rib 23 and the reinforcing plate 22 are arranged in parallel. For example, the reinforcing rib 23 and the reinforcing plate 22 may extend in the same direction and be arranged in parallel with each other, so that they can share the load and further enhance the strengthening effect of the reinforcement component on the overall stability of the speaker structure.

[0089] In this embodiment, optionally, the length of the connecting portion 10 is any value between 77.5-79 mm, and / or the width of the connecting portion 10 is any value between 57-59 mm. This ensures that the connecting portion 10 has a suitable length, avoiding both insufficient length for installation and excessive length for deformation. For example, the length of the connecting portion 10 can be 78.3 ± 0.5 mm, and it can also be 77.5 mm, 77.7 mm, or 79 mm, etc. This embodiment does not limit the specific length value of the connecting portion 10. Similarly, the connecting portion 10 has a suitable width, avoiding both insufficient width for installation and excessive width for deformation. For example, the width of the connecting portion 10 can be 58 ± 0.5 mm, and it can also be 57 mm, 57.3 mm, 58.8 mm, 59 mm, etc. This embodiment does not limit the specific width value of the connecting portion 10.

[0090] In summary, the speaker structure of the embodiments of this application can include at least the following advantages:

[0091] In this embodiment, the speaker structure includes a connecting portion and a sound-emitting portion; the sound-emitting portion is connected to the connecting portion; the sound-emitting end of the sound-emitting portion is positioned facing the driver's area of ​​the vehicle. This allows the driver in the driver's area to obtain a better acoustic sound quality experience through the sound-emitting portion, increases the sense of spatial distance in the overall sound field of the cabin, reduces interference and masking caused by other structures on sound propagation to the driver, improves the overall acoustic sound quality and sound effect of the vehicle audio system, and also prevents sound propagated by the speaker from directly entering the driver's ears, thus improving the driver's auditory experience and the overall vehicle audio effect.

[0092] Reference Figures 8 to 9 This application also proposes a loudspeaker assembly, which includes a mounting member 50 and a loudspeaker structure. The mounting member 50 has a mounting opening 51, the speaker section 20 of the loudspeaker structure is embedded in the mounting opening 51, and the connecting part 10 of the loudspeaker structure is connected to the outer periphery of the mounting opening 51. In this way, the mounting member 50 is used to match and install the loudspeaker structure, specifically the mounting opening 51 is used to accommodate the speaker section 20, and the connecting part 10 is used to fix the loudspeaker structure to the mounting member 50.

[0093] In this embodiment, the mounting member 50 can be a one-piece sheet metal part, which is disposed on the dashboard 70.

[0096] Optionally, in this embodiment, the speaker assembly includes a cover that covers the outside of the connecting portion 10 and the sound-emitting portion 20. The cover has a mesh structure at a position opposite to the sound-emitting portion 20. In this way, by covering the connecting portion 10 and the sound-emitting portion 20 of the speaker structure with the cover and setting the mesh structure at a position opposite to the sound-emitting portion 20, the sound amplification effect is improved.

[0097] Optionally, in this embodiment, the mounting member 50 is provided with a second mounting hole 52 and a third mounting hole 53, the third mounting hole 53 being located on the outer periphery of the second mounting hole 52; the speaker assembly includes a cover, the cover having a protruding mounting portion, the mounting portion being inserted into the third mounting hole 53. Thus, the cover is fixedly mounted via the third mounting hole 53, giving the cover better reliability and stability, preventing the cover from shaking or loosening. And / or, the speaker assembly includes a decorative element, the decorative element covering the outer side of the cover. Thus, the cover is hidden inside the decorative element, giving the speaker assembly a better appearance. For example, the decorative element can be a sponge with a leather surface, which has better sound amplification and appearance.

[0098] Optionally, in this embodiment, the mounting member 50 includes a protruding positioning member 54, which engages with the positioning opening 12 of the speaker structure. Specifically, the positioning member 54 protrudes towards the speaker structure, and the positioning member 54 is adapted to the positioning opening 12, that is, the two have the same cross-sectional shape and the same or similar size, and the positioning member 54 can be inserted into the positioning opening 12. In this way, the positioning member 54 achieves the installation and positioning of the speaker structure.

[0099] For example, in the embodiments of this application, the positioning element 54 can be a positioning post, which can be cylindrical, conical, or prismatic, or other irregular structures. It can be set according to actual needs. The specific shape of the positioning post is not limited in the embodiments of this application.
