The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

Therefore, the features defined with “first” and “second” can explicitly or implicitly include one or more of the features.

[0030] In the embodiments of the present application, the terms "comprising", "containing" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such a process, method, article or device. Without more limitations, the element defined by the sentence "including a" does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0031] In the embodiments of the present application, the words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design presented as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Rather, the use of the words such as "exemplary" or "for example" is intended to present relevant concepts in a concrete manner.

[0032] The embodiments of the present application provide an interactive device, which can be applied to vehicles, smart devices, etc. The term "vehicle" or other similar terms used in the present application include a broad sense of motor vehicles: for example, passenger cars including sport utility vehicles (SUV), buses, trucks, various commercial vehicles; watercraft including various boats and ships, and aircraft, etc.; and including hybrid vehicles, electric vehicles, hybrid electric vehicles, hydrogen-powered vehicles and other alternative fuel vehicles (for example, fuels derived from resources other than petroleum). Smart devices can include various portable computer programs. For example, access control devices, camera devices, smart home appliances, smart terminals, etc.

[0033] In some technical solutions, the interactive device multiplexes the same component as an induction assembly and a sound emitting assembly respectively, but due to the limitation of connection mode and size, it is difficult to balance the sound emitting and induction requirements, resulting in poor sound emitting effect and induction sensitivity.

[0034] To solve the above technical problems, the interactive device of the embodiments of the present application sets the first connecting piece at the outer edge of the vibrating piece, reduces the influence of the first connecting piece and the external component on the vibrating piece, thereby improving the sound emitting effect; the second connecting piece is fully attached to the induction piece, and the induction piece is easy to vibrate under the driving of the second connecting piece, so as to obtain higher sensitivity. The interactive device can balance the good input and output interaction, and improve the user's use experience.

[0035] ReferenceFigure 1 and Figure 2 The interactive device of the embodiment of the application comprises a sound producing assembly 100 and a sensing assembly 200. The sound producing assembly 100 comprises a vibrating member 110 and a first connecting member 120 connected with each other. The vibrating member 110 is used to generate vibration, and the first connecting member 120 is arranged corresponding to the outer edge of the vibrating member 110. The sensing assembly 200 comprises a sensing member 210 and a second connecting member 220 connected with each other. The sensing member 210 is used to detect vibration. The first connecting member 120 and the second connecting member 220 are both used to connect an external member 400 to transmit vibration.

[0036] In the embodiment of the application, the vibrating member 110 can be a piezoelectric member, a magnetostrictive member, etc. The sensing member 210 can also be a piezoelectric member, a magnetostrictive member, etc. The sensing member 210 and the vibrating member 110 can adopt the same or different structural forms. For example, the vibrating member 110 and the sensing member 210 are both piezoelectric members. The vibrating member 110 vibrates to produce sound under the action of electric current by using the inverse piezoelectric effect, and can be used as a loudspeaker. The sensing member 210 vibrates with the external vibration and generates electric current by using the piezoelectric effect, and can be used as a microphone, a touch sensor, etc.

[0037] In the embodiment of the application, the first connecting member 120 is used to connect the vibrating member 110 to the external member 400. The first connecting member 120 can be a buckle structure, a screw structure, an adhesive structure, etc. For example, the first connecting member 120 is double-sided adhesive tape provided with adhesive layers on two opposite sides. The vibrating member 110 and the external member 400 are respectively adhered to the two opposite sides of the first connecting member 120.

[0038] In the embodiment of the application, the first connecting member 120 is arranged corresponding to the outer edge of the vibrating member 110, i.e. the middle part of the vibrating member 110 is left empty and the first connecting member 120 is not arranged thereon, so as to reduce the influence of the first connecting member 120 and the external member 400 on the vibrating member 110, make the vibration deformation more sufficient, enable the vibration with a larger amplitude to be generated, and provide a better sound producing effect.

[0039] In the embodiment of the application, the second connecting member 220 is used to connect the sensing member 210 to the external member 400. The second connecting member 220 and the first connecting member 120 can adopt the same or different structures. The second connecting member 120 can be annular with the middle part left empty, or can be attached to the sensing member 210 on the whole surface. For example, the second connecting member 220 is double-sided adhesive tape provided with adhesive layers on two opposite sides. The sensing member 210 and the external member 400 are respectively adhered to the two opposite sides of the second connecting member 220.

[0040] In the embodiment of the application, the second connecting member 220 is attached to the sensing member 210 on the whole surface. The sensing member 210 is easy to deform and is easily driven to deform by the second connecting member 220, and thus the vibration transmitted by the external member 400 can be detected, so that the sensing member 210 has a higher sensitivity.

[0041] It should be noted that the material of the first connecting member 120 and the second connecting member 220 has an influence on the transmission of vibration, and a relatively soft material has a weakening effect on vibration, which can be used to reduce the interference of adverse vibration; a relatively hard material can effectively transmit vibration and reduce vibration attenuation. For example, the first connecting member 120 is made of hard rubber material, and the second connecting member 220 is made of soft rubber material.

[0042] The technical scheme of the embodiment of the present application, the sound generating assembly 100 generates vibration through the vibration piece 110, and transmits the vibration to the external member 400 through the first connecting member 120 to drive the external member 400 to vibrate and sound; the induction assembly 200 transmits the vibration of the external member 400 through the second connecting member 220, so as to detect the vibration of the external member 400.

[0043] On this basis, the first connecting member 120 is arranged at the outer edge of the vibration piece 110, which reduces the influence of the first connecting member 120 and the external member 400 on the vibration piece 110, and can provide better sound generating effect; the second connecting member 220 is fully attached to the induction piece 210, and the induction piece 210 is easy to vibrate under the driving of the second connecting member 220, so as to obtain higher sensitivity. The interactive device can balance the good input and output interaction, and improve the user's use experience.

[0044] It should be noted that the vibration piece 110 can stretch / contract along the length direction, the width direction or the radial direction, so as to vibrate along the thickness direction. The length direction, the width direction or the radial direction of the vibration piece 110 is the extension plane of the vibration piece 110, and the vibration direction of the vibration piece 110 is the thickness direction. Correspondingly, the induction piece 210 also stretches / contracts along the length direction, the width direction or the radial direction, so as to vibrate along the thickness direction. The length direction, the width direction or the radial direction of the induction piece 210 is the extension plane of the induction piece 210, and the vibration direction of the induction piece 210 is the thickness direction.

[0045] In the embodiment of the present application, the vibration direction of the vibration piece 110 and the vibration direction of the induction piece 210 can be parallel or at an angle, and the extension plane of the vibration piece 110 and the extension plane of the induction piece 210 can be parallel or at an angle, and the vibration piece 110 and the induction piece 210 can be arranged on the same or different external members 400.

[0046] Referring to Figure 1 and Figure 2 In a possible embodiment of the present application, the vibration piece 110 and the induction piece 210 are arranged on the same structure surface of the same external member 400, the extension plane of the vibration piece 110 is parallel to the extension plane of the induction piece 210, and correspondingly, the vibration direction of the vibration piece 110 is also parallel to the vibration direction of the induction piece 210.

[0047] In the embodiments of the present application, the shape of the vibration piece 110 along its extension plane can be square, diamond, triangle, hexagon, circle, ellipse, etc., and the shape of the induction piece 210 along its extension plane can also be square, diamond, triangle, hexagon, circle, ellipse, etc. The shapes of the induction piece 210 and the vibration piece 110 can be the same or different.

[0048] In an example, the vibration piece 110 is a rectangular structure, and the induction piece 210 is a circular structure; in another example, the vibration piece 110 is a circular structure, and the induction piece 210 is a square structure; in yet another example, the vibration piece 110 and the induction piece 210 are both circular structures.

[0049] It should be noted that the vibration piece 110 has a first area along its extension plane, and the induction piece 210 has a second area along its extension plane, and the first area and the second area can be equal or unequal. It can be understood that the first area of the vibration piece 110 is larger, and the driving force for vibration is stronger, so that a vibration with a larger amplitude can be generated, and a good sound production effect can be obtained; the second area of the induction piece 210 is smaller, so that the induction piece 210 is more easily deformed by the second connecting piece 220, and the sensitivity of detection is higher.

[0050] In order to improve the input / output performance of the interactive device, in some possible embodiments of the present application, the ratio of the second area to the first area ranges from 1 / 3 to 1 / 1, for example, the ratio of the second area to the first area is 1 / 3, 2 / 3, 1 / 1, etc. Alternatively, the second area of the induction piece 210 is smaller than the first area of the vibration piece 110.

[0051] The interactive device of the embodiments of the present application limits the ratio of the second area to the first area within a reasonable range, which can not only make the vibration piece 110 have good sound production performance, but also improve the sensitivity of the induction piece 210, and help to improve the input / output performance of the interactive device.

[0052] In some possible embodiments of the present application, the vibration piece 110 is a rectangular structure, the long side dimension of the vibration piece 110 is 85 mm, and the short side dimension is 35 mm; the induction piece 210 is a square or circular structure, and the side length or diameter of the induction piece 210 ranges from 20 mm to 40 mm, for example, the induction piece 210 is circular, and the diameter is 20 mm, 30 mm, 40 mm, etc.

[0053] It should be noted that, in the case where the vibration piece 110 and the induction piece 210 are arranged on the same structure surface of the external member 400, the vibration piece 110 and the induction piece 210 can be stacked along the vibration direction, in other words, the projection of the induction piece 210 along the vibration direction of the vibration piece 110 can overlap or partially overlap the projection of the vibration piece 110. Alternatively, along the structure surface of the external member 400, the vibration piece 110 and the induction piece 210 can be arranged at intervals, in other words, the projection of the vibration piece 110 along the vibration direction of the vibration piece 110 can not overlap the projection of the induction piece 210. It can be understood that, in the case where the projections do not overlap, along the structure surface of the external member 400, the outer edge of the vibration piece 110 and the outer edge of the induction piece 210 have an interval size W10 in the extension plane. The larger the interval size W10, the smaller the mutual influence between the vibration piece 110 and the induction piece 210, which is beneficial to improve the performance of each other; the smaller the interval size W10, the smaller the space occupied by the interaction device, which is beneficial to miniaturization and convenient arrangement.

[0054] With reference to Figure 1 In some possible embodiments of the present application, in the case where the projections do not overlap, the interval size W10 is less than or equal to 100 mm, for example, 0 mm, 10 mm, 30 mm, 50 mm, 80 mm, 90 mm, 100 mm, etc.

[0055] In the embodiments of the present application, in the case where the projections of the vibration piece 110 and the induction piece 210 along the vibration direction overlap, the projection of the geometric center of the vibration piece 110 and the projection of the geometric center of the induction piece 210 can overlap or not overlap; for example, the projection of the geometric center of the vibration piece 110 and the projection of the geometric center of the induction piece 210 can overlap.

[0056] With reference to Figure 3 In some possible embodiments of the present application, in the case where the projections of the vibration piece 110 and the induction piece 210 along the vibration direction overlap, the induction piece 210 can be spaced apart from the first connecting piece 120 along the extension direction to reduce the mutual influence between the vibration piece 110 and the induction piece 210.

[0057] It can be understood that, in the case where the projection of the geometric center of the vibration piece 110 and the projection of the geometric center of the induction piece 210 do not overlap, or the projection of the induction piece 210 partially overlaps the projection of the vibration piece 110, the vibration piece 110 is connected to a plurality of first connecting pieces 120 arranged at intervals to avoid the induction piece 210.

[0058] It should be noted that the size of the vibration piece 110 along the vibration direction affects the sound generation performance thereof, and the vibration piece 110 has a large size along the thickness direction, so that a strong driving force is easily generated to improve the amplitude and optimize the sound generation effect; the size of the induction piece 210 along the vibration direction also affects the detection performance of the induction piece 210, and the induction piece 210 has a small size along the thickness direction, so that the induction piece 210 is easily driven to vibrate by the external component 400, and the sizes of the vibration piece 110 and the induction piece 210 along the thickness direction can be set within a suitable range according to actual requirements, so as to have good sound generation effect and induction sensitivity, respectively.

[0059] With reference to Figure 1 and Figure 3 In some possible embodiments of the present application, the vibration piece 110 has a first thickness size H10 along the vibration direction thereof, and the induction piece 210 has a second thickness size H20 along the thickness direction thereof. The first thickness size H10 and the second thickness size H20 can be the same or different. For example, the first thickness size H10 is greater than the second thickness size H20, so that the vibration piece 110 can generate a stronger driving force to improve the sound generation effect and improve the sensitivity of the induction piece 210.

[0060] For example, the first thickness size H10 ranges from 0.2 mm to 2.0 mm, such as 0.2 mm, 0.6 mm, 1.0 mm, 1.4 mm, 1.8 mm, 2.0 mm, etc.; and the second thickness size H20 ranges from 0.2 mm to 1.1 mm, such as 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, 1.1 mm, etc. For example, the first thickness size H10 of the vibration piece 110 and the second thickness size H20 of the induction piece 210 are both 1.0 mm.

[0061] With reference to Figure 2 , Figure 5 and Figure 6 In some possible embodiments of the present application, the vibration piece 110 and the induction piece 210 in the form of piezoelectricity can include a substrate and one or more piezoelectric parts arranged on the substrate. When one piezoelectric part is arranged on the substrate, the piezoelectric part and the connecting piece can be arranged on the same or different sides of the substrate, and when two piezoelectric parts are arranged on the substrate, the two piezoelectric parts are arranged on opposite sides of the substrate along the vibration direction, and one of the piezoelectric parts and the connecting piece are arranged on the same side of the substrate.

[0062] For example, the vibration piece 110 includes a first substrate 111 and a first piezoelectric part 112, and the first piezoelectric part 112 is connected to one side or both sides of the first substrate 111 in the vertical vibration direction; the induction piece 210 includes a second substrate 211 and a second piezoelectric part 212, and the second piezoelectric part 212 is connected to the side of the second substrate 211 away from the second connecting piece 220, wherein the first piezoelectric part 112 is used for vibration sound, and the second piezoelectric part 212 is used for vibration detection.

[0063] In the embodiment of the application, the first connecting piece 120 is connected to the vibration piece 110, specifically, the first connecting piece 120 is connected to the first substrate 111. Correspondingly, the second connecting piece 220 is connected to the induction piece 210, specifically, the second connecting piece 220 is connected to the second substrate 211.

[0064] On this basis, the size of the substrate in the vibration direction can range from 0.1 mm to 0.3 mm, for example, 0.1 mm, 0.2 mm, 0.3 mm, etc., and the size of the first substrate 111 and the second substrate 211 in the vibration direction can be the same or different; the size of the piezoelectric part in the vibration direction can range from 0.1 mm to 0.8 mm, for example, 0.1 mm, 0.3 mm, 0.5 mm, 0.7 mm, 0.8 mm, etc., and the size of the first piezoelectric part 112 and the second piezoelectric part 212 in the vibration direction can be the same or different.

[0065] It should be noted that the first connecting piece 120 is used to provide connection and also provides support for the vibration piece 110, so as to isolate the vibration piece 110 from the external member 400, and reduce the possibility of contact between the two in the vibration process to affect each other. Referring to Figure 1 and Figure 3 The third thickness dimension H30 of the first connecting piece 120 in the vibration direction.

[0066] In the case where the projection of the vibration piece 110 and the projection of the induction piece 210 have a spacing size, and the first substrate 111 is not provided with the first piezoelectric part 112 on the side close to the first connecting piece 120, the third thickness dimension H30 is greater than the maximum amplitude of the first substrate 111 in the vibration direction.

[0067] In the case where the projection of the vibration piece 110 and the projection of the induction piece 210 have a spacing size, and the first substrate 111 is provided with the first piezoelectric part 112 on the side close to the first connecting piece 120, the third thickness dimension H30 is greater than the sum of the maximum amplitude of the first substrate 111 in the vibration direction and the size of the first piezoelectric part 112 in the vibration direction.

[0068] In the case where the projection of the inductor 210 and the projection of the vibration piece 110 at least partially overlap in the vibration direction, and the first piezoelectric portion 112 is not provided on the side of the first substrate 111 close to the first connecting piece 120, the third thickness dimension H30 is greater than the sum of the maximum amplitude of the first substrate 111 in the vibration direction, the maximum amplitude of the second substrate 211 in the vibration direction, the dimension of the second piezoelectric portion 212 in the vibration direction, the dimension of the second substrate 211 in the vibration direction, and the dimension of the second connecting piece 220 in the vibration direction.

[0069] In the case where the projection of the inductor 210 and the projection of the vibration piece 110 at least partially overlap in the vibration direction, and the first piezoelectric portion 112 is provided on the side of the first substrate 111 close to the first connecting piece 120, the third thickness dimension H30 is greater than the sum of the maximum amplitude of the first substrate 111 in the vibration direction, the dimension of the first piezoelectric portion 112 in the vibration direction, the maximum amplitude of the second substrate 211 in the vibration direction, the dimension of the second piezoelectric portion 212 in the vibration direction, the dimension of the second substrate 211 in the vibration direction, and the dimension of the second connecting piece 220 in the vibration direction.

[0070] Referring to Figure 1 and Figure 3 In some possible embodiments of the present application, the third thickness dimension H30 of the first connecting piece 120 in the vibration direction ranges from 3 mm to 4.8 mm, for example, 3 mm, 3.4 mm, 3.8 mm, 4.0 mm, 4.4 mm, 4.8 mm, etc., and the sum of the dimension of the vibration piece 110 and the dimension of the first connecting piece 120 in the vibration direction ranges from 3.2 mm to 6.8 mm, for example, 3.2 mm, 4.0 mm, 5.0 mm, 6.0 mm, 6.8 mm, etc. For example, the sum of the first thickness dimension H10 and the third thickness dimension H30 is 5.0 mm.

[0071] Referring to Figure 3 In some possible embodiments, the projection of the inductor 210 and the projection of the vibration piece 110 at least partially overlap in the vibration direction, in order to reduce possible interference between the vibration piece 110 and the inductor 210 during vibration, the spacing distance H40 of the inductor 210 and the vibration piece 110 in the thickness direction ranges from 1.6 mm to 4.0 mm, for example, 1.6 mm, 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm, etc. In an example, the spacing distance H40 is set to 2.0 mm.

[0072] It can be understood that the second connecting piece 220 can have a smaller dimension in the vibration direction, so as to connect the inductor 210 with the external member 400, and facilitate the inductor 210 to follow the deformation vibration of the external member 400.

[0073] It should be noted that the inductor 210 is connected to the external component 400 through the second connecting member 220, and the second connecting member 220 can be arranged on a partial surface or a whole surface of the inductor 210 on the side facing the external component 400. It can be understood that the area of the inductor 210 connected by the second connecting member 220 is larger, and the vibration transmitted is more complete, which is more conducive to the detection of the inductor 210. Referring to Figure 1 and Figure 3 In some possible embodiments of the present application, the inductor 210 and the second connecting member 220 have the same size along the extension direction, that is, the inductor 210 is completely attached to the external component 400 through the second connecting member 220.

[0074] Referring to Figure 4 In some possible embodiments of the present application, the interactive device can further include a working circuit 300, and the vibration member 110 and the inductor 210 are electrically connected to the working circuit 300 to work under the driving of the working circuit 300.

[0075] In some possible embodiments of the present application, the working circuit 300 includes a processor 310, and the processor 310 filters the vibration generated by the vibration member 110 through a software filtering algorithm, so that the processor 310 can process the signal generated by the external vibration.

[0076] It can be understood that the vibration generated by the vibration member 110 can be filtered through the processor 310, so that the vibration member 110 and the inductor 210 work at the same time. In the case of external vibration, for example, the user touches, taps, etc., the processor 310 filters the vibration generated by the vibration member 110, so that the inductor 210 can effectively detect the external vibration.

[0077] It should be noted that the vibration member 110 and the inductor 210 using the piezoelectric principle, under the adaptation of the working circuit 300, the vibration member 110 can also serve as an input device, and the inductor 210 can also serve as an output device. In one possible embodiment of the present application, the working circuit 300 further includes a switching circuit for switching the working mode of the vibration member 110 and / or the inductor 210, such as an output mode for vibration and sound, a sensing mode for detecting external vibration, etc.

[0078] In the embodiments of the present application, the first connecting member 120 can be arranged annularly along the outer edge of the vibration member 110, and the profile formed by the arrangement of the first connecting member 120 is the same as or similar to the outer profile of the vibration member 110. For example, the outer profile of the vibration member 110 is circular, and the arrangement profile of the first connecting member 120 is also circular. For another example, the outer profile of the vibration member 110 is square, and the arrangement profile of the first connecting member 120 is also square. It can be understood that the outer profile of the vibration member 110 and the arrangement profile of the first connecting member 120 can also be regular or irregular figures such as ellipse, triangle, hexagon, diamond, etc.

[0079] In the embodiments of the present application, the outer edge of the first connecting member 120 can be projected on the vibration direction and can be overlapped with the outer edge of the vibration member 110, that is, the outer edge of the first connecting member 120 is arranged coplanarly with the outer edge of the vibration member 110. In this way, the first connecting member 120 is arranged as close to the edge of the vibration member 110 as possible, so that the vibration member 110 can be deformed to generate vibration.

[0080] In the embodiments of the present application, the first connecting member 120 is arranged annularly along the outer edge of the vibration member 110, and the first connecting member 120 can be one or more, and the plurality of first connecting members 120 are symmetrically distributed along the outer edge of the vibration member 110. For example, the plurality of first connecting members 120 are centrally symmetrically distributed about the geometric center of the vibration member 110, and the plurality of first connecting members 120 are symmetrically distributed about the central axis of the vibration member 110. In addition, the plurality of first connecting members 120 can also be distributed at equal intervals along the outer edge of the vibration member 110.

[0081] It can be understood that the first connecting member 120 is arranged at intervals along the outer edge of the vibration member 110, which can reduce the total volume of the first connecting member 120 on the vibration member 110, reduce the space occupation, and on the other hand, the gap can also be used to avoid other components, so as to facilitate the arrangement of the interactive device.

[0082] In some possible embodiments of the present application, one first connecting member 120 is arranged on the vibration member 110, the first connecting member 120 is arranged annularly, and the outer profile of the first connecting member 120 is similar to the outer profile of the vibration member 110. The first connecting member 120 arranged as a whole has simple structure, is convenient for production, has good structural consistency, can effectively transmit vibration, and can improve the vibration effect.

[0083] In order to reduce the influence of the first connecting member 120 on the vibration of the first piezoelectric part 112, with reference to Figure 2 , Figure 5 and Figure 6In some possible embodiments of the present application, the first piezoelectric part 112 is connected to the central part of the first substrate 111, and the first connecting part 120 is connected to the edge part of the first substrate 111. The first connecting part 120 and the first piezoelectric part 112 are arranged at intervals in the extension direction, that is, the first connecting part 120 and the first piezoelectric part 112 do not contact and there is a gap between them.

[0084] In the embodiments of the present application, the piezoelectric part can be a whole structure, that is, the surface of the piezoelectric part is a continuous surface, the whole piezoelectric part has better integrity, and the area ratio of the piezoelectric part to the substrate to which it is connected is high, so that a vibration with higher strength and larger amplitude can be generated. The piezoelectric part can also be a perforated structure, that is, the piezoelectric part is also annular like the first connecting part 120, and the piezoelectric part is arranged in a ring shape with a central part left empty, occupying less space and facilitating the provision of clearance for other components and facilitating the layout.

[0085] In some possible embodiments of the present application, the connecting surface of the second piezoelectric part 212 to the second substrate 211 is a continuous surface, and the second piezoelectric part 212 is attached to the second substrate 211 in its entirety. The surface of the first piezoelectric part 112 and the surface of the second piezoelectric part 212 can be square or circular. In this case, the connecting surface of the first piezoelectric part 112 to the first substrate 111 is a continuous surface. Alternatively, the first piezoelectric part 112 is annular in structure, the outer contour and the inner contour of the piezoelectric part are consistent, and the piezoelectric part is a square annular structure or a circular annular structure.

[0086] In the embodiments of the present application, the piezoelectric part can be composed of one or more layers of piezoelectric ceramics stacked together, and the multiple layers of piezoelectric ceramics are stacked along the vibration direction. It can be understood that the more piezoelectric ceramics stacked in the piezoelectric part, the stronger the driving force provided, and the easier it is to drive the corresponding substrate to deform and vibrate. Conversely, the less piezoelectric ceramics stacked in the piezoelectric part, the smaller the space occupied, and the easier it is to be driven by the corresponding substrate to deform. Therefore, the number of layers of piezoelectric ceramics in the piezoelectric part can be set according to actual needs in order to balance the sound generation performance and the sensing performance. In some possible embodiments of the present application, the number of layers of piezoelectric ceramics of the sensing part 210 and the number of layers of piezoelectric ceramics of the vibrating part 110 can be the same or different.
