Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0023] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0024] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0025] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0026] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0027] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0028] This application provides an interactive device applicable to vehicles, smart devices, etc. The term "vehicle" or other similar terms used in this application broadly encompass motor vehicles: for example, passenger vehicles including SUVs, buses, trucks, and various commercial vehicles; watercraft including various boats and ships, and aircraft; and including hybrid vehicles, electric vehicles, hybrid-electric vehicles, hydrogen-powered vehicles, and other alternative fuel vehicles (e.g., fuels derived from resources other than petroleum). Smart devices may include various devices capable of carrying computer programs. Examples include access control devices, camera equipment, smart home appliances, and smart terminals.

[0029] In some technical solutions, the interactive device includes a vibration component and a connector. The connector connects the vibration component to an external component and transmits the vibration. Due to limitations in the connection method, the vibration component generates high-frequency vibrations above 2000 Hz, producing a sharp and harsh sound that affects the user experience. Furthermore, the vibration component has a poor low-frequency response and insufficient vibration amplitude, resulting in the absence of low-frequency sounds below 300 Hz.

[0030] To solve the above-mentioned technical problems, the interactive device provided in this application embodiment arranges the connectors in a ring along the outer edge of the vibration component, and the central area of ​​the vibration component is in an empty state. This central area is not easily restricted by external components and connectors, so that the deformation and vibration of the vibration component are more complete, and can generate vibration with a larger amplitude, suppress high-frequency vibration and obtain a better low-frequency response.

[0031] Reference Figure 1 and Figure 2 The interactive device in this application embodiment includes a vibration component 100 and a connector 200. The vibration component 100 is used to vibrate to produce sound. The connector 200 is arranged in a ring along the outer edge of the vibration component 100. The connector 200 is used to connect the vibration component 100 to an external component and transmit vibration.

[0032] In this embodiment, the connector 200 is arranged along the outer edge of the vibration assembly 100, meaning the outline formed by the arrangement of the connector 200 is the same as or similar to the outer outline of the vibration assembly 100. For example, the outer outline of the vibration assembly 100 is circular; the outline of the connector 200 is also circular. Alternatively, the outer outline of the vibration assembly 100 is square; the outline of the connector 200 is also square. It is understood that the outer outline of the vibration assembly 100 and the outline of the connector 200 can also be regular or irregular shapes such as ellipses, triangles, hexagons, and rhombuses.

[0033] In this embodiment of the application, the vibration component 100 can be a piezoelectric component, a magnetostrictive component, etc. The vibration component 100 extends / contracts along its length direction, width direction or radial direction to vibrate along the thickness direction. That is, the vibration direction of the vibration component 100 is set along the thickness direction, the extension plane of the vibration component 100 is perpendicular to the thickness direction, and the extension direction of the vibration component 100 is any direction within its extension plane.

[0034] In this embodiment of the application, the connector 200 is used to connect the vibration assembly 100 to an external component. The connection can be a snap-fit ​​structure, a screw connection structure, an adhesive structure, etc. For example, the connector 200 is a double-sided adhesive with an adhesive layer on both sides, and the vibration assembly 100 and the external component are respectively bonded to the opposite sides of the connector 200.

[0035] It should be noted that the material of the connector 200 affects the transmission of vibration. A softer material weakens vibration and can be used to reduce interference from unfavorable vibrations; a harder material can effectively transmit vibration and reduce vibration attenuation. For example, connectors 200 are all made of hard plastic.

[0036] In the technical solution of this application embodiment, the vibration component 100 is connected to the external component through the connector 200. The connector 200 can transmit the vibration generated by the vibration component 100 to the external component, or transmit the vibration generated by the external component to the vibration component 100. Since the connector 200 is arranged in a ring along the outer edge of the vibration component 100, compared with the solution of attaching to the entire surface, the middle part of the vibration component 100 in this application embodiment is in an unoccupied state, and is less restricted by the external component and the connector 200, so that the vibration deformation is more complete, and a larger amplitude vibration can be generated, suppressing high frequency vibration and obtaining a better low frequency response.

[0037] It should be noted that the connector 200 is located on the outer edge of the vibration assembly 100. In the direction perpendicular to the vibration direction, there may or may not be a gap between the outer edge of the connector 200 and the outer edge of the vibration assembly 100.

[0038] Reference Figure 1 and Figure 2In some possible embodiments of this application, the projection of the outer edge of the connector 200 along the vibration direction of the vibration assembly 100 overlaps with the projection of the outer edge of the vibration assembly 100, that is, the outer edge of the connector 200 and the outer edge of the vibration assembly 100 are coplanar. This arrangement makes the connector 200 as close to the edge as possible relative to the vibration assembly 100, so as to reduce the restriction on the deformation and vibration of the vibration assembly 100.

[0039] It is understandable that if the size of the connector 200 is smaller along the extension plane of the vibration component 100, there will be fewer restrictions on the vibration component 100, so that the vibration component can generate large vibrations and improve low-frequency characteristics. If the size of the connector 200 is larger, the vibration transmission effect will be better and a more stable connection can be provided. Therefore, the size of the connector 200 can be set within a reasonable range according to actual needs in order to balance low-frequency characteristics and connection stability.

[0040] In order to balance connection stability and sound production effect, in one possible embodiment of this application, the area ratio of the connector 200 and the vibration component 100 on the extended plane is in the range of 1 / 25 to 1 / 9. For example, the area ratio of the two can be 1 / 25, 1 / 20, 1 / 15, 1 / 9, etc.

[0041] Reference Figure 1 and Figure 4 In one possible embodiment of this application, the outer contours of both the connector 200 and the vibration component 100 are circular, and the inner contour of the connector 200 is also circular, meaning the connector 200 is a ring structure. The distance between the outer and inner contours of the connector 200 is its width dimension W10. The outer contour of the vibration component 100 has a second radius R20, and the ratio of the width dimension W10 to the second radius R20 ranges from 1 / 5 to 1 / 3. For example, the ratio of the width dimension W10 to the second radius R20 can be 1 / 5, 1 / 4, 1 / 3, etc.

[0042] Accordingly, the inner contour of the connector 200 may have a first radius R10, and the ratio of the first radius R10 to the second radius R20 may be in the range of 2 / 3 to 4 / 5. For example, the ratio of the first radius R10 to the second radius R20 may be 2 / 3, 5 / 7, 3 / 4, 7 / 9, 4 / 5, etc.

[0043] Reference Figure 1 and Figure 2 In some possible embodiments, the width dimension W10 of the connector 200 in the extension direction ranges from 3 mm to 6 mm. For example, the width dimension W10 of the connector 200 is 3 mm, 4 mm, 5 mm, or 6 mm. Here, the width dimension W10 is the distance between the outer contour and the inner contour of the connector 200.

[0044] The technical solution of this application embodiment limits the area ratio of the connector 200 and the vibration component 100 on the extended plane to a reasonable range, which can provide a stable connection and vibration transmission effect, and has little impact on the vibration performance of the vibration component 100, thus improving the low-frequency performance of the vibration component 100.

[0045] It should be noted that the connector 200 is arranged in a ring along the outer edge of the vibration assembly 100. There can be one or more connectors 200. One connector 200 is a ring structure, or at least two connectors 200 are arranged in a ring along the outer edge of the vibration assembly 100.

[0046] In this embodiment, the plurality of connectors 200 may be symmetrically distributed along the outer edge of the vibration assembly 100. For example, the plurality of connectors 200 may be centrally symmetrically distributed about the geometric center of the vibration assembly 100; in addition, the plurality of connectors 200 may also be distributed at equal intervals along the outer edge of the vibration assembly 100.

[0047] It is understandable that the connectors 200 are spaced apart on the outer edge of the vibration component 100. On the one hand, this can reduce the overall volume of the connectors 200 on the vibration component 100 and reduce space occupation. On the other hand, the gaps can also be used to avoid other components, so as to facilitate the layout of the interactive device.

[0048] To improve the vibration effect, refer to Figure 1 and Figure 2 In some possible embodiments of this application, a connector 200 is provided on the vibration assembly 100. The connector 200 is arranged in a ring shape, and the outer contour of the connector 200 is similar to the outer contour of the vibration assembly 100. The overall connector 200 has a simple structure, is easy to manufacture, and has good structural consistency, which can effectively transmit vibration to improve the vibration effect.

[0049] Reference Figure 2 , Figure 3 and Figure 4 In some possible embodiments of this application, the vibration component 100 includes a substrate 110 and a piezoelectric element 120. The piezoelectric element 120 is connected to the substrate 110. Based on the inverse piezoelectric effect, the piezoelectric element 120 can deform under the action of current to drive the substrate to vibrate, so that the vibration component 100 can be used as an output device, such as a loudspeaker.

[0050] In this embodiment, the connection between the connector 200 and the vibration component 100 is specifically that the connector 200 is connected to the substrate 110, and the vibration generated by the piezoelectric component 120 is transmitted to the connector 200 via the substrate 110.

[0051] To reduce the vibration impact of connector 200 on piezoelectric element 120, refer to Figure 3 and Figure 4 In some possible embodiments of this application, the piezoelectric element 120 is connected to the central portion of the substrate 110, and the connector 200 is connected to the edge portion of the substrate 110. The connector 200 and the piezoelectric element 120 are spaced apart in the extension direction, that is, the connector 200 and the piezoelectric element 120 do not contact each other and there is a gap between them.

[0052] In the technical solution of this application embodiment, the connector 200 and the piezoelectric element 120 are spaced apart in the extension direction. The connector 200 imposes less restriction on the piezoelectric element 120, so that the piezoelectric element 120 can generate a larger amplitude vibration, thereby improving the low-frequency performance of the vibration assembly 100.

[0053] It should be noted that the piezoelectric element 120 can be an integral structure, that is, the connection surface between the piezoelectric element 120 and the substrate 110 is a continuous surface. The piezoelectric element 120 has better integrity and a higher area ratio relative to the substrate 110, which can generate vibrations with higher intensity and larger amplitude.

[0054] Reference Figure 3 and Figure 4 In some possible embodiments of this application, the piezoelectric element 120 has a continuous square or circular structure; the piezoelectric element 120 has good integrity and can generate a large amplitude performance to improve the low-frequency performance of the vibration assembly 100.

[0055] It should be noted that the outer contour of the piezoelectric element 120 and the outer contour of the substrate 110 may be the same or different. When the outer contour of the piezoelectric element 120 and the outer contour of the substrate 110 are similar, the structural consistency between the two is better, and vibration can be transmitted between them more effectively. In addition, the outer contour of the piezoelectric element 120 and the inner contour of the connector 200 may be the same or different. When the outer contour of the piezoelectric element 120 and the inner contour of the connector 200 are similar, the structural consistency of the substrate 110 between the connector 200 and the piezoelectric element 120 is better, which facilitates vibration transmission on the substrate 110.

[0056] To improve vibration transmission, refer to Figure 2 and Figure 4 In some possible embodiments of this application, the outer contour of the substrate 110, the outer contour of the connector 200, the inner contour of the connector 200, and the outer contour of the piezoelectric element 120 all adopt the same shape. That is, when the sizes are different, the substrate 110, the connector 200, and the piezoelectric element 120 are all square, round, rhomboid, or other shapes.

[0057] In the technical solution of this application embodiment, the substrate 110, the connector 200 and the piezoelectric element 120 adopt the same contour structure, which has good structural consistency and facilitates the transmission of vibration among the three to improve the vibration effect.

[0058] It is understandable that on the extended plane, the piezoelectric element 120 is larger in size, which generates a larger driving force, making it easier to deform the substrate 110 and resulting in a larger vibration intensity; the piezoelectric element 120 is smaller in size, resulting in a larger gap with the connector 200, less influence from the connector 200, and a more stable vibration.

[0059] In order to balance the vibration intensity and the stability of vibration, in some possible embodiments of this application, the area ratio of the piezoelectric element 120 and the substrate 110 on the extended plane ranges from 1 / 10 to 4 / 5. For example, the area ratio of the two can be 1 / 10, 1 / 5, 2 / 5, 3 / 5, 4 / 5, etc.

[0060] Reference Figure 3 In one possible embodiment of this application, the outer contours of both the piezoelectric element 120 and the substrate 110 are circular. The outer contour of the substrate 110 is the same as the outer contour of the aforementioned vibration assembly 100. Therefore, the outer contour of the substrate 110 has a second radius R20, and the outer contour of the piezoelectric element 120 has a third radius R30. The ratio of the third radius R30 to the second radius R20 ranges from 1 / 3 to 11 / 15. For example, the ratio of the third radius R30 to the second radius R20 can be 1 / 3, 2 / 5, 1 / 2, 8 / 15, 2 / 3, 11 / 15, etc. The third radius R30 of the outer contour of the piezoelectric element 120 ranges from 20 mm to 50 mm, for example, 20 mm, 30 mm, 40 mm, 50 mm, etc.

[0061] The technical solution of this application embodiment limits the area ratio of the piezoelectric element 120 and the substrate 110 on the extended plane to a reasonable range, which can provide stable connection and vibration transmission effect, as well as improve vibration intensity and vibration stability.

[0062] In this embodiment, the piezoelectric element 120 can be formed by stacking one or more layers of piezoelectric ceramics, with the layers stacked along the vibration direction. It is understood that a larger number of stacked piezoelectric ceramics in the piezoelectric element 120 provides a stronger driving force, making it easier to cause the substrate 110 to deform and vibrate, which is suitable for use as an output component in the vibration assembly 100. Conversely, a smaller number of stacked piezoelectric ceramics in the piezoelectric element 120 occupies less space and is more easily deformed by the substrate 110 to generate an electrical signal, making it suitable for use as an input component in the vibration assembly 100.

[0063] Correspondingly, if the size of the substrate 110 along the vibration direction is smaller, it is easier to deform to generate vibration, and the driving force required for the piezoelectric element 120 is also smaller; if the size of the substrate 110 along the vibration direction is larger, the support stability is better, and the stability during vibration is better, which is beneficial to improving the smoothness of high-frequency vibration. Therefore, the size of the substrate 100 along the vibration direction can be set within a reasonable range according to actual needs, so as to balance the requirements of deformation vibration and stability.

[0064] To balance the performance of the vibration assembly 100, refer to Figure 2 In one possible embodiment of this application, the piezoelectric element 120 is stacked with multiple layers of piezoelectric ceramics along the vibration direction, and the first thickness dimension H10 along the vibration direction ranges from 0.1 mm to 0.8 mm, such as 0.1 mm, 0.3 mm, 0.5 mm, 0.7 mm, 0.8 mm, etc.; the second thickness dimension H20 of the substrate 110 along the vibration direction ranges from 0.1 mm to 0.3 mm, such as 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, etc.

[0065] It should be noted that one or more piezoelectric elements 120 may be provided on the substrate 110. When one piezoelectric element 120 is provided on the substrate 110, the piezoelectric element 120 and the connector 200 may be provided on the same or different sides of the substrate 110. When two piezoelectric elements 120 are provided on the substrate 110, the two piezoelectric elements 120 are respectively provided on opposite sides of the substrate 110 along the vibration direction, and one of the piezoelectric elements 120 and the connector 200 are provided on the same side of the substrate 110.

[0066] Understandably, the connector 200 serves both to provide a connection and to support the vibration assembly 100, thereby isolating the vibration assembly 100 from external components and reducing the possibility of them coming into contact and influencing each other during vibration. Therefore, when the piezoelectric element 120 and the connector 200 are disposed on different sides of the substrate 110, the dimension of the connector 200 along the vibration direction is greater than the maximum amplitude of the substrate 110 along the vibration direction; when the piezoelectric element 120 and the connector 200 are disposed on the same side of the substrate 110, the dimension of the connector 200 along the vibration direction is greater than the sum of the maximum amplitude of the substrate 110 along the vibration direction and the first thickness dimension H10 of the piezoelectric element 120.

[0067] In some possible embodiments, the third thickness dimension H30 of the connector 200 along the vibration direction is between 2 mm and 3 mm. For example, the third thickness dimension H30 of the connector 200 along the vibration direction is 2 mm, 2.5 mm, or 3 mm.

[0068] Based on this, the present application also provides a smart device, which includes the interactive device of the present application. The smart device can be a personal computer (PC), laptop computer, mobile phone, all-in-one computer, handheld computer, tablet computer or portable device (such as mobile phone, navigation and positioning device), industrial control computer, smart home device (such as smart speaker, access control device), etc.

[0069] In the intelligent device of this application embodiment, the connector 200 is arranged in a ring along the outer edge of the vibration component 100, and the middle part of the vibration component 100 is in an unoccupied state, not restricted by external components and connector 200, so that the vibration deformation is more complete, and a larger amplitude vibration can be generated, suppressing high frequency vibration and obtaining a better low frequency response.

[0070] Furthermore, this application embodiment also provides a vehicle, the vehicle including at least one structural member, and the interactive device of this application embodiment is connected to the structural member.

[0071] In this embodiment, the structural components include at least one of the following: exterior body panels, interior body panels, and vehicle components. The vehicle components are connected to the exterior body panels or interior body panels. Exterior body panels include roof panels, hoods, glove box lids, pillars (such as B-pillars), front / rear fenders, doors, bumpers, roof racks, and rearview mirror covers; interior body panels include headliners, floors, dashboards, door panels, center console panels, pillar guards, and window sills; vehicle components include seats, body beams, body pillars, steering wheels, armrests, rearview mirrors, and sun visors.

[0072] For example, the interactive device can be used as a sound-generating device for an Acoustic Vehicle Alerting System (AVAS). For instance, the vibration assembly 100 can be attached to the hood of the vehicle via the connector 200. Alternatively, the vibration assembly 100 can be attached to the door via the connector 200 to replace a vehicle speaker or for external noise reduction.

[0073] In the vehicle of this application embodiment, the connecting member 200 is arranged in a ring along the outer edge of the vibration component 100, and the middle part of the vibration component 100 is in an unoccupied state, not restricted by external components and connecting member 200, so that the vibration deformation is more complete, and a larger amplitude vibration can be generated, suppressing high frequency vibration and obtaining a better low frequency response.

[0074] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4In one possible embodiment of this application, the interactive device includes a vibration component 100 and a connector 200. The vibration component 100 is fixed to an external component via the connector 200. The vibration component 100 can generate vibration to produce sound as an output component, or it can generate an electrical signal as an input component under the vibration of the external component.

[0075] Based on this, the vibration assembly 100 includes a substrate 110 and piezoelectric elements 120 disposed on both sides of the substrate 110 along the vibration direction. Both the substrate 110 and the piezoelectric elements 120 are circular structures, and the connector 200 is an annular structure. The piezoelectric elements 120 are disposed in the middle of the substrate 110, and the connector 200 is disposed at the edge of the substrate 110. The piezoelectric elements 120 and the connector 200 are spaced apart along the extension direction.

[0076] The interactive device of this application, with the connector 200 arranged on the edge of the substrate 110, facilitates the effective vibration of the piezoelectric element 120, increases the vibration amplitude, and enhances its low-frequency characteristics. This allows the vibration frequency of the vibration component 100 to reach below 300Hz, while optimizing the high-frequency characteristics. This prevents the high-frequency response of the vibration component 100 above 2000Hz from continuously increasing, ensuring that the vibration frequency is within a relatively stable range, and the difference between the peaks and troughs of the generated sound is within 10 decibels (dB).

[0077] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
