[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0035] According to the first aspect of this application, see Figure 1 and Figure 2 The present disclosure provides a vehicle sound-generating assembly. The vehicle sound-generating assembly includes a first exciter 1, which includes a first mounting base 11 and a first vibration shaft 12. The first vibration shaft 12 is movably connected to the first mounting base 11. The first mounting base 11 is configured to be fixedly mounted on a bumper 2. The first vibration shaft 12 is configured to abut against the bumper 2 and resonate with the bumper 2 to generate sound.

[0036] It is understood that by placing the first vibration shaft 12 of the first exciter 1 in contact with the bumper 2 and controlling the first vibration shaft 12 of the first exciter 1 to vibrate, the vibration generated by the first vibration shaft 12 can be transmitted to the bumper 2, thereby driving the bumper 2 to resonate and causing the bumper 2 to vibrate and emit sound. In other words, the present application achieves vehicle sound generation by causing the first exciter 1 to vibrate the bumper 2. The sound generated by the bumper 2 can be transmitted directly outward, without being trapped within the vehicle. This reduces the sound transmitted into the vehicle cabin and effectively improves the driver and passenger experience.

[0037] Furthermore, when the bumper 2 vibrates, the entire bumper 2 generates sound, thereby improving the distribution uniformity of the sound emitted by the vehicle.

[0038] Compared to related art solutions that use speakers to make a vehicle emit sound, this application directly mounts the first exciter 1 on the bumper 2. Direct contact between the first exciter 1 and the bumper 2 creates resonance, causing the bumper 2, and thus the vehicle, to emit sound. The first exciter 1 does not directly generate sound, but rather produces sound by driving the bumper 2 to resonate. This avoids the situation in related art where speakers directly emit sound and transmit noise into the vehicle cabin. This allows the vehicle to emit a warning sound to pedestrians while preventing excessive noise from entering the vehicle cabin. Furthermore, compared to installing a speaker, the first exciter 1 is much simpler to install and has fewer requirements for the installation environment.

[0039] It is understood that resonance refers to the phenomenon in which when one object vibrates at a specific frequency, another object will also vibrate at the same frequency. The first vibration shaft 12 can generate resonance in the bumper 2 by emitting a specific vibration frequency. The vibration frequency of the first vibration shaft 12 can be adjusted based on the material and structure of the bumper 2 to ensure that the first vibration shaft 12 can drive the bumper 2 to resonate.

[0040] It should be noted that the vehicle's bumper 2 is exposed to the outside world. Therefore, the sound generated by the first vibration axis 12 driving the bumper 2 to resonate can be directly transmitted to the outside world, effectively preventing the sound from propagating inside the vehicle and causing the noise to be noticeable even in the vehicle cabin.

[0041] In some examples, the bumper 2 is, for example, a plastic bumper 2 or a stainless steel bumper 2 .

[0042] In some embodiments, see Figure 2 and Figure 3 The first exciter 1 also includes a voice coil 13, a magnetic member 14 and a circuit board 15. The voice coil 13 is sleeved on the first vibration shaft 12. The connecting end of the first vibration shaft 12 protrudes from the first mounting seat 11 and is used to abut against the bumper 2. The connecting end and the magnetic member 14 are respectively located on opposite sides of the first mounting seat 11. The circuit board 15 is electrically connected to the voice coil 13, and the circuit board 15 is used to change the current direction of the voice coil 13.

[0043] It is understood that the circuit board 15 can control the direction of the current flowing through the voice coil 13, allowing the voice coil 13 to switch between attraction and repulsion with the magnetic member 14. In other words, when the direction of the current flowing through the voice coil 13 changes, the voice coil 13 moves closer to or farther from the magnetic member 14, simultaneously driving the first vibration shaft 12 with it. This controls the reciprocating motion of the first vibration shaft 12 relative to the magnetic member 14, allowing the first vibration shaft 12 to vibrate and transmit the vibration to the bumper 2, causing the bumper 2 to resonate and produce sound.

[0044] In some examples, the circuit board 15 integrates a power supply unit and a control unit. The control unit is used to control the power supply unit to supply power to the voice coil 13 , and the control unit can control the current output direction of the power supply unit, thereby achieving control of the direction of the current delivered to the voice coil 13 .

[0045] In some embodiments, see Figure 2 and Figure 3Along the axial direction of the first vibration shaft 12, the first vibration shaft 12 includes a vibration shaft body 121 and a connecting portion 122 that are connected to each other. The vibration shaft body 121 is installed on the first mounting seat 11. A connecting surface 123 is formed on the side of the connecting portion 122 away from the vibration shaft body 121. The connecting surface 123 is used to abut against the bumper 2. The cross-sectional area of the connecting portion 122 is larger than the cross-sectional area of the vibration shaft body 121.

[0046] It is understandable that the connection surface 123 of the first vibration shaft 12 abuts against the bumper 2 , so that the first vibration shaft 12 and the bumper 2 are in surface contact, ensuring that the first vibration shaft 12 can effectively drive the bumper 2 to resonate.

[0047] It can be understood that the cross-sectional area of the connecting portion 122 for abutting the bumper 2 is set to be larger than the cross-sectional area of the vibration shaft body 121 installed on the first mounting seat 11, thereby increasing the contact area between the first vibration shaft 12 and the bumper 2, so that the vibration of the first vibration shaft 12 can be effectively transmitted to the bumper 2, ensuring that the bumper 2 can resonate under the vibration of the first vibration shaft 12.

[0048] In some examples, the area of the connecting surface 123 is the maximum cross-sectional area of the connecting portion 122 .

[0049] In some embodiments, see Figure 2 and Figure 3 The first exciter 1 is provided with a connecting structure 16, and the connecting structure 16 is used to connect the first exciter 1 and the vehicle.

[0050] It is understandable that the first exciter 1 can be connected to the vehicle via the connecting structure 16 , so that the first exciter 1 can be stably mounted on the vehicle, so as to abut against the bumper 2 and drive the bumper 2 to resonate.

[0051] In some examples, the connection structure 16 is, for example, a connection hole. Fasteners are inserted through the connection hole and connected to the vehicle, thereby connecting the first exciter 1 to the vehicle. The connection structure 16 can also be an adhesive layer that adheres the first exciter 1 to the vehicle. It should be noted that this is merely an example of the connection structure 16 and does not constitute a specific limitation.

[0052] According to a second aspect of the present application, the present disclosure provides a vehicle bumper assembly. The vehicle bumper assembly includes a bumper 2 and the aforementioned vehicle sound-generating assembly. A first mounting base 11 of a first exciter 1 is fixedly mounted to the bumper 2. A first vibration axis 12 of the first exciter 1 abuts against the bumper 2 and is capable of resonating with the bumper 2 to generate sound.

[0053] It is understood that by placing the first vibration shaft 12 of the first exciter 1 in contact with the bumper 2 and controlling the first vibration shaft 12 of the first exciter 1 to vibrate, the vibration generated by the first vibration shaft 12 can be transmitted to the bumper 2 to drive the bumper 2 to resonate, causing the bumper 2 to vibrate and emit sound. That is, the present application achieves vehicle sound generation by causing the first exciter 1 to drive the bumper 2 to vibrate. The sound generated by the bumper 2 can be transmitted directly outward, reducing the sound transmitted into the vehicle cabin and effectively improving the driver and passenger experience. Furthermore, when the bumper 2 vibrates, the entire bumper 2 generates sound, improving the uniformity of the sound distribution emitted by the vehicle.

[0054] According to the third aspect of this application, please refer to Figure 4 and Figure 5 The present disclosure provides a vehicle. The vehicle includes a vehicle body 3, a bumper 2, and the vehicle sound generating assembly described above. The bumper 2 is connected to the vehicle body 3. A first exciter 1 is fixedly mounted on the vehicle body 3. A first mounting base 11 of the first exciter 1 is fixedly mounted on the bumper 2. A first vibration axis 12 of the first exciter 1 abuts against the bumper 2 and is capable of resonating with the bumper 2 to generate sound.

[0055] It is understood that by placing the first vibration shaft 12 of the first exciter 1 in contact with the bumper 2 and controlling the first vibration shaft 12 of the first exciter 1 to vibrate, the vibration generated by the first vibration shaft 12 can be transmitted to the bumper 2 to drive the bumper 2 to resonate, causing the bumper 2 to vibrate and emit sound. That is, the present application achieves vehicle sound generation by causing the first exciter 1 to drive the bumper 2 to vibrate. The sound generated by the bumper 2 can be transmitted directly outward, reducing the sound transmitted into the vehicle cabin and effectively improving the driver and passenger experience. Furthermore, when the bumper 2 vibrates, the entire bumper 2 generates sound, improving the uniformity of the sound distribution emitted by the vehicle.

[0056] In some examples, the vehicle may be a fuel vehicle, a plug-in hybrid vehicle, or a new energy vehicle, etc., which is not specifically limited in this application.

[0057] In some embodiments, the first exciter 1 is located on a side of the bumper 2 facing the vehicle body 3 .

[0058] It is understandable that installing the first exciter 1 on the side of the bumper 2 facing the vehicle body 3, that is, installing the first exciter 1 between the bumper 2 and the vehicle body 3, can avoid the first exciter 1 being exposed to the outside and reduce the impact of the external environment on the first exciter 1.

[0059] In some embodiments, the first exciter 1 is located on a side of the bumper 2 facing away from the vehicle body 3 .

[0060] It can be understood that the bumper 2 is located between the first exciter 1 and the vehicle body 3, that is, the first exciter 1 is located outside the vehicle body 3. When the first exciter 1 generates vibration to drive the bumper 2 to vibrate, the sound generated by the vibration of the first exciter 1 will be directly transmitted to the outside of the vehicle body 3, and is difficult to be transmitted to the inside of the vehicle body 3, further reducing the noise transmitted to the inside of the vehicle body 3.

[0061] In some embodiments, the bumper 2 includes a first portion disposed inside the vehicle body 3 and a second portion disposed outside the vehicle body 3 , and the first exciter 1 is mounted on the first portion.

[0062] It can be understood that installing the first exciter 1 at the first portion within the vehicle body 3 protects the first exciter 1 from external environmental factors, thereby ensuring that the first exciter 1 can operate stably.

[0063] In some embodiments, the vehicle body 3 is provided with a receiving space, the first part is at least partially disposed in the receiving space, and the first exciter 1 is disposed in the receiving space.

[0064] It is understandable that by utilizing the accommodation space to install the first exciter 1, that is, installing the first exciter 1 inside the vehicle body 3, the influence of external environmental factors on the first exciter 1 can be avoided, thereby ensuring the working stability of the first exciter 1. At the same time, the utilization rate of the accommodation space can be improved.

[0065] In some examples, the accommodation space may refer to the front compartment of the vehicle body 3 , or may refer to any other space in the vehicle body 3 that can accommodate the first exciter 1 .

[0066] In some embodiments, see Figure 4 and Figure 5 The vehicle also includes a body structure 4 and a second exciter 5. The body structure 4 is connected to the vehicle body 3. The body structure 4 is at least partially arranged outside the vehicle body 3. The second exciter 5 includes a second mounting seat 51 and a second vibration shaft 52. The second vibration shaft 52 is movably connected to the second mounting seat 51. The second mounting seat 51 is fixedly mounted on the body structure 4. The second vibration shaft 52 abuts against the body structure 4 and can resonate with the body structure 4 to emit sound.

[0067] It is understood that the second vibration shaft 52 can drive the body structure 4 to resonate and produce sound, thereby causing the vehicle to emit sound, thereby providing a warning to pedestrians. Furthermore, because the body structure 4 is at least partially disposed outside the vehicle body 3, the sound generated by the resonance of the body structure 4 can be transmitted directly outward, effectively preventing the sound from being blocked within the vehicle body 3 and reducing the sound transmitted into the vehicle body 3.

[0068] In some examples, the body structure 4 includes at least one of a front cover, a trunk lid, a body side panel, a fender, a headlight, and a vehicle logo. It should be noted that the body structure 4 is merely an example here and is not specifically limited to the body structure 4.

[0069] In some embodiments, a vehicle body structure member 4 and a second exciter 5 connected to each other are provided at least one of the left side, the right side, and the rear of the vehicle body 3 .

[0070] It can be understood that by setting a second exciter 5 at the body structure 4 on the left side of the vehicle body 3, the body structure 4 on the left side of the vehicle body 3 can resonate with the second exciter 5 to emit sound, so that the left side of the vehicle can emit sound, which can serve as a warning to pedestrians.

[0071] By setting a second exciter 5 at the body structure 4 on the right side of the vehicle body 3, the body structure 4 on the right side of the vehicle body 3 can resonate with the second exciter 5 to emit sound, so that the right side of the vehicle can emit sound, which can serve as a warning to pedestrians.

[0072] By setting a second exciter 5 at the body structure 4 at the rear of the vehicle body 3, the body structure 4 at the rear of the vehicle body 3 can resonate with the second exciter 5 to emit sound, so that the rear of the vehicle can emit sound, which can serve as a warning to pedestrians.

[0073] In some examples, the vehicle includes a control component, and the second exciters 5 on the left, right, and rear sides of the vehicle body 3 are all electrically connected to the control component. The control component controls the operation of the second exciters 5 on the left, right, and rear sides of the vehicle body 3 according to the vehicle's direction of travel. For example, when the vehicle moves to the left, the control component can control the operation of the second exciter 5 on the left side, so that the second exciter 5 on the left side resonates with the left body structure 4 and emits sound, thereby better warning pedestrians on the left side.

[0074] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.

[0075] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
