[0010] Another embodiment of the present application provides an electronic device, wherein a connecting part is provided in a connecting area, and a substrate is connected to an external component through the connecting part. Since the piezoelectric element and the connecting area are respectively provided on two structural sides, the size of the connecting part along the vibration direction of the substrate is reduced, so that the vibration transmission path is shorter, thereby facilitating the transmission of vibration between the substrate and the external component and reducing the loss of vibration during the transmission process.

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0047] In the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, "multiple" means two or more.

[0048] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

[0049] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0050] In the embodiments of the present application, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising that element.

[0051] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described 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 designs. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0052] The embodiments of the present application provide an electronic device, which can be applied to scenarios that require vibration for sound generation, or require vibration or sound detection. For example, the electronic device can be used for vehicle human-machine interaction, and can also be used in scenarios that require human-machine interaction in electronic devices such as computers and mobile phones.

[0053] The electronic device may include a substrate and a piezoelectric member. The piezoelectric member is a component made of piezoelectric material and has piezoelectric effect and inverse piezoelectric effect. The piezoelectric effect means that when the piezoelectric member undergoes mechanical deformation under an external force, an electrical signal will be generated; the inverse piezoelectric effect means that the piezoelectric member can generate mechanical deformation under the drive of an electrical signal. Specifically, if an electric field with the same direction as its polarization direction is applied to the piezoelectric member, the action of the electric field increases the polarization intensity. At this time, the distance between the positive and negative bound charges in the piezoelectric member also increases, that is, the piezoelectric member generates an extensional deformation along the polarization direction. Similarly, if the direction of the applied external electric field is opposite to the polarization direction, the piezoelectric member generates a contraction deformation along the polarization direction.

[0054] Here, piezoelectric materials are further divided into inorganic piezoelectric materials, organic piezoelectric materials and composite piezoelectric materials. Inorganic piezoelectric materials are further divided into piezoelectric crystals and piezoelectric ceramics. Piezoelectric crystals generally refer to piezoelectric single crystals, specifically crystals grown in a long-range ordered manner according to the crystal space lattice. This crystal structure has no center of symmetry and thus has piezoelectricity. Such as quartz (quartz crystal), lithium gallate, lithium germanate, germanium titanate, and ferroelectric transistor lithium niobate, tantalum lithium niobate, etc. Piezoelectric ceramics generally refer to piezoelectric polycrystals. Piezoelectric ceramics are polycrystals obtained by mixing necessary component raw materials, forming, and high-temperature sintering, which are randomly assembled by fine grains obtained from the solid-phase reaction and sintering process between powder particles, such as: barium titanate BT, lead zirconate titanate PZT, modified lead zirconate titanate, lead metaniobate, lead barium lithium niobate PBLN, modified lead titanate PT, etc.

[0055] Organic piezoelectric materials, also known as piezoelectric polymers, such as polyvinylidene fluoride (PVDF) (films) and other organic piezoelectric (film) materials represented by it. Such materials and their materials are flexible, have low density, low impedance, and high piezoelectric voltage constant (g), etc. Composite piezoelectric materials are piezoelectric composite materials composed of inorganic piezoelectric ceramics and organic polymer resins, and have the properties of both inorganic and organic piezoelectric materials.

[0056] In the related art, piezoelectric components are attached to both opposite sides of the substrate in an electronic device. However, since piezoelectric components are provided on both sides of the substrate, it is easier to have problems with inconsistent fitting flatness of the piezoelectric components on both sides due to process defects (for example, the lamination fitting flatness between multiple driving sheets that make up the piezoelectric component, and for another example, the fitting flatness between the piezoelectric component and the substrate), which in turn leads to uneven deformation of the piezoelectric components on both sides under the drive of an electrical signal, thereby affecting the vibration of the substrate and even the sound generation effect of the electronic device. In addition, the connection wire bundles of the piezoelectric components in the related art are not reasonably arranged. For example, cylindrical connection wire bundles are used, and the solder joints connecting the connection wire bundles and the piezoelectric components are coated with glue to play a role in protection and waterproofing. Both the connection wire bundles and the glue will occupy a large space in the vibration direction of the substrate, which is not conducive to the installation and use of the electronic device, nor is it conducive to the vibration conduction between the electronic device and external components.

[0057] To solve one or more of the above technical problems, referring to Figure 1 and Figure 2 , the electronic device provided in the embodiment of the present application includes a substrate 1 and a piezoelectric component 2. The piezoelectric component 2 is attached to the substrate 1. The piezoelectric component 2 is used to generate deformation in response to a first electrical signal or generate a second electrical signal in response to external vibration. The substrate 1 is used to vibrate following the deformation of the piezoelectric component 2, or transfer external vibration to the piezoelectric component 2; the substrate 1 includes two relatively arranged structural sides 11, and one of the structural sides 11 is provided with two connection areas 12. The connection areas 12 are used to connect external components 7; along the deformation direction of the piezoelectric component 2, the piezoelectric component 2 is located between the two connection areas 12; and only one of the two structural sides 11 is provided with the piezoelectric component 2.

[0058] In the embodiment of the present application, the substrate 1 can be a plate-like structure, a block-like structure, etc. Referring to Figure 1 and Figure 2 , in a possible embodiment of the present application, the substrate 1 is a rectangular plate-like structure, and the two structural sides 11 are respectively the two sides of the substrate 1 along the thickness direction.

[0059] In the embodiment of the present application, the shape of the piezoelectric component 2 can be a symmetrically arranged shape, such as a rectangle, a circle, an ellipse, or other shapes with a symmetric structure.

[0060] In the embodiments of the present application, the connection region 12 is the region on the substrate 1 connected to the external component 7, and is used to connect the external component 7. That is, the substrate 1 is connected to the external component 7 through the connection region 12. It should be noted that the connection region 12 may be directly connected to the external component 7, or a connecting member 3 may be provided in the connection region 12 so that the connection region 12 is indirectly connected to the external component 7 through the connecting member 3.

[0061] In the embodiments of the present application, the shape of the connection region 12 may be circular, square, triangular, rhombic, trapezoidal, regular hexagonal, or a combination of several shapes, etc. Refer to Figure 1 and Figure 3 , in a possible embodiment of the present application, the connection region 12 is a rectangular structure, and the length direction of the connection region 12 is arranged along the width direction of the structure side 11. The connection region 12 may be arranged close to the edge of the substrate 1 to provide a more stable structure. Among them, the two connection regions 12 may be symmetrically distributed on the same structure side 11 so that the substrate 1 is more evenly stressed.

[0062] In the embodiments of the present application, there are various possible examples of the external component 7 according to the layout position of the electronic device. For example, when the electronic device is a sound-emitting device and / or a sensor of an electronic terminal, the external component 7 may be the main board, housing, screen, etc. of the electronic terminal; when the electronic device is a sound-emitting device and / or a sensor of a vehicle, the external component 7 may be the vehicle body. Exemplarily, the vehicle body may include the outer shell plate of the vehicle body (such as vehicle body sheet metal), interior panel or flexible surface, vehicle components (such as seats, armrest boxes, bumper shells, steering wheels), etc.

[0063] In the embodiments of the present application, the piezoelectric member 2 is specifically attached to the substrate 1 in that the surface profile of the side of the piezoelectric member 2 facing the substrate 1 is the same as the surface profile of the side of the substrate 1 facing the piezoelectric member 2. For example, both are flat surfaces or both are arc surfaces with the same curvature. Exemplarily, the surfaces of the piezoelectric member 2 and the substrate 1 that are attached to each other are both flat surfaces.

[0064] In the embodiments of the present application, the piezoelectric member 2 can generate deformation by utilizing the inverse piezoelectric effect to drive the substrate 1 to vibrate. Exemplarily, when an electric field is applied to the piezoelectric member 2, that is, when the piezoelectric member 2 responds to the first electrical signal, the piezoelectric member 2 generates deformation under the action of the electric field. When the electric field changes, the deformation direction of the piezoelectric member 2 changes accordingly, thereby generating deformations in different directions. The deformation of the piezoelectric member 2 can drive the deformation of the substrate 1, so that the substrate 1 generates vibration or vibrates to produce sound.

[0065] In the embodiment of the present application, the deformation direction of the piezoelectric element 2 is related to its polarization direction. When the direction of the electric field applied to the piezoelectric element 2 is the same as the polarization direction of the piezoelectric element 2, the piezoelectric element 2 expands and deforms along its polarization direction. On the contrary, when the direction of the electric field applied to the piezoelectric element 2 is opposite to the polarization direction of the piezoelectric element 2, the piezoelectric element 2 contracts and deforms along its polarization direction. Exemplarily, the polarization direction of the piezoelectric element 2 is set along the length direction of the structural side 11 of the base 1, and with the switching of the direction of the electric field, the piezoelectric element 2 switches between expansion and contraction deformations along the length direction of the structural side 11 of the base 1, thereby driving the base 1 to deform and generating vibration perpendicular to the horizontal plane where the structural side 11 is located when the base 1 is not deformed. The vibration direction at this time is the first direction X.

[0066] Specifically, when the piezoelectric element 2 on the side of the base 1 facing the external component 7 expands and deforms, and / or, when the piezoelectric element 2 on the side of the base 1 away from the external component 7 contracts and deforms, the base 1 deforms and protrudes towards the external component 1 along the first direction X; when the piezoelectric element 2 on the side of the base 1 facing the external component 7 contracts and deforms, and / or, when the piezoelectric element 2 on the side of the base 1 away from the external component 7 expands and deforms, the base 1 deforms and protrudes away from the external component 1 along the first direction X. The base 1 switches between the two deformations to generate vibration along the first direction X.

[0067] It should be noted that the piezoelectric element 2 of the piezoelectric type can also be used as a sensor. Exemplarily, when external vibration is transmitted to the piezoelectric element 2 through a medium such as the base 1 or air, the piezoelectric element 2 deforms with the external vibration. Under the piezoelectric effect, the deformation of the piezoelectric element 2 generates an electric current, thereby generating a second electrical signal. Therefore, the electronic device can be used as a vibration, touch, or sound sensor. For example, an in-vehicle microphone on a vehicle, etc.

[0068] Refer to Figure 4 , the electronic device can be used in cooperation with the working circuit 5. The working circuit 5 includes a controller. The controller can be the central processing unit of the in-vehicle terminal. The controller is electrically connected to the piezoelectric element 2 of the electronic device. The controller can transmit a first electrical signal to the piezoelectric element 2, and / or, receive the second electrical signal generated by the piezoelectric element 2. In addition, the working circuit 5 can also include a power supply component, a power amplifier (such as an audio power amplifier), a switching component, a digital-to-analog converter, a digital signal processing (Digital Signal Processing) chip, a human-machine interaction component such as a button, a display screen, etc. The embodiment of the present application does not limit this.

[0069] In the embodiments of the present application, the extension direction of the structural side 11 can be any direction parallel to the structural side 11, which can be the length direction of the structural side 11, the width direction of the structural side 11, etc. For example, the two connection regions 12 are located on both sides of the structural side 11 of the substrate 1 along the length direction, and the piezoelectric element 2 is located in the middle of the structural side 11 of the substrate 1 along the length direction. The two connection regions 12 can be provided on the same structural side 11.

[0070] It should be noted that in some embodiments, both the connection region 12 and the piezoelectric element 2 are provided only on one of the two structural sides 11. Therefore, for example, the connection region 12 and the piezoelectric element 2 can be provided on the same structural side 11, that is, the piezoelectric element 2 is located on the side of the substrate 1 facing the external component 7; for another example, the connection region 12 and the piezoelectric element 2 can also be respectively provided on the two structural sides 11, that is, the piezoelectric element 2 is located on the side of the substrate 1 away from the external component 7. It can be understood that when the connection region 12 and the piezoelectric element 2 are respectively provided on the two structural sides 11, in the projection along the direction perpendicular to the structural side 11, the projection of the piezoelectric element 2 is still located between the projections of the two connection regions 12.

[0071] In the electronic device according to the embodiments of the present application, the substrate 1 provides an installation basis for the piezoelectric element 2, and the substrate 1 further includes two relatively arranged structural sides 11, and one of the structural sides 11 is provided with a connection region 12, and the connection region 12 is used for connecting to the external component 7. The substrate 1 can vibrate following the deformation of the piezoelectric element 2, that is, the substrate 1 can vibrate driven by the deformation generated by the piezoelectric element 2 in response to the first electrical signal, and transmit the vibration to the external component 7 through the connection region 12. The substrate 1 can also transmit the external vibration to the piezoelectric element 2, that is, receive the external vibration through the connection region 12 and transmit the vibration to the piezoelectric element 2, so that the piezoelectric element 2 generates a second electrical signal in response to the external vibration.

[0072] On this basis, the piezoelectric element 2 is attached to the substrate 1, so that the piezoelectric element 2 and the substrate 1 can vibrate synchronously to improve the vibration transmission effect. And along the deformation direction of the piezoelectric element 2, the piezoelectric element 2 is located between the two connection regions 12, that is, both ends of the substrate 1 are used for connecting to the external component 7 to transmit vibration, and the substrate 1 does not have a free end, which is more conducive to vibration transmission. And only one of the two structural sides 11 is provided with the piezoelectric element 2, reducing the influence of the process defects of the piezoelectric element 2 on the performance of the electronic device. For example, since only one side of the substrate 1 is provided with the piezoelectric element 2, there is no problem of poor flatness consistency in the attachment between the piezoelectric element 2 on this side and the piezoelectric element 2 on the other side. Therefore, during deformation, it will not be disturbed by the uneven deformation caused by the poor flatness consistency in the attachment, thereby improving the vibration effect.

[0073] Compared with the solution in the related art where piezoelectric elements 2 are provided on both sides of the substrate 1, in the technical solution of the embodiment of the present application, only one of the two structural sides 11 of the substrate 1 is provided with a piezoelectric element 2, reducing the impact of process defects of the piezoelectric element 2 on the performance of the electronic device and improving the vibration effect.

[0074] To improve the vibration effect, referring to Figure 2 and Figure 3 , in some possible embodiments of the present application, the piezoelectric element 2 includes at least two driving sheets 21, and the at least two driving sheets 21 are stacked in sequence in a direction away from the substrate 1.

[0075] In the embodiment of the present application, the number of driving sheets 21 can be two or more, and the structures of the multiple driving sheets 21 can be the same or different. The driving sheet 21 is used to generate deformation in response to the first electrical signal, and / or generate the second electrical signal in response to external vibration. The driving sheets 21 with the same structure have better consistency during deformation. Exemplarily, the piezoelectric element 2 includes four driving sheets 21, and the structures and sizes of the four driving sheets 21 are the same, and they are stacked in sequence along the thickness direction of the substrate 1.

[0076] In the electronic device of the embodiment of the present application, the piezoelectric element 2 can include two or more driving sheets 21, and the driving sheet 21 can generate deformation. Since the multiple driving sheets 21 are stacked in sequence in a direction away from the substrate 1, that is, stacked in sequence along the vibration direction of the substrate 1, the deformation forces of the two or more driving sheets 21 can be superimposed on each other to drive the substrate 1 to generate a more powerful vibration, such as increasing the amplitude of the substrate 1, etc., thereby improving the vibration effect. It can be understood that the deformation force refers to the force generated by the driving sheet to expand and contract under the action of an electric field.

[0077] To facilitate the electrical connection of the piezoelectric element 2, referring to Figure 2 , in some possible embodiments of the present application, at least two driving sheets 21 are electrically connected through a connecting portion 22.

[0078] In the embodiment of the present application, the connecting portion 22 can be a conductive member made of a conductive material. The conductive member sequentially connects at least two driving sheets 21, thereby electrically connecting these driving sheets 21 to each other. The conductive member can be arranged inside the driving sheet 21 or outside the driving sheet 21. Exemplarily, the connecting portion 22 is a through hole provided between the driving sheets 21, that is, a through hole is opened on the driving sheet 21, and a metal coating is applied in the through hole, etc., thereby electrically connecting the driving sheet 21 to the adjacent driving sheet 21.

[0079] In the embodiments of the present application, the connecting part 22 can connect all the driving sheets 21, that is, the connecting part 22 passes through all the driving sheets 21 in the piezoelectric element 2 in sequence; alternatively, the connecting part 22 only connects two adjacent driving sheets 21. For example, connecting parts 22 are arranged on both sides of the driving sheet 21 along the length direction, where the connecting part 22 on one side is used to connect the driving sheet 21 above it, and the connecting part 22 on the other side is used to connect the driving sheet 21 below it.

[0080] In the electronic device according to the embodiment of the present application, the piezoelectric element 2 is provided with a connecting part 22, and at least two driving sheets 21 are electrically connected through the connecting part 22. Only by electrically connecting the connecting part 22 with the relevant circuit, the structure is simpler, and it is also convenient for the fitting arrangement of multiple driving sheets 21.

[0081] For the convenience of the electrical connection of the piezoelectric element 2, referring to Figure 2 and Figure 11 , in some possible embodiments of the present application, the piezoelectric element 2 includes at least two connecting parts 22, and at least two connecting parts 22 correspond to different polarities, and at least two connecting parts 22 are arranged at the edge of the piezoelectric element 2.

[0082] In the embodiments of the present application, the polarities corresponding to the connecting part 22 can be positive and negative. For example, the piezoelectric element 2 includes a first connecting part 22a and a second connecting part 22b. Under the action of an electric field, the driving sheet 21 can stretch or contract and deform along its polarization direction; when an opposite electric field is applied, the direction of deformation of the driving sheet 21 along its polarization direction is also opposite. It can be understood that when the working circuit 5 provides an alternating current drive, the driving sheet 21 will cycle between stretching deformation and contracting deformation to drive the substrate 1 to switch the protruding direction during deformation, so that the substrate 1 vibrates along the first direction X.

[0083] In the embodiments of the present application, the connecting part 22 is arranged at the edge of the piezoelectric element 2. Specifically, the connecting part 22 includes a connection point exposed outside the piezoelectric element 2, and this connection point is used to connect the working circuit 5, and this connection point is arranged on the side of the piezoelectric element 2 away from the substrate 1 and is located at the edge position of this side of the piezoelectric element 2.

[0084] In the electronic device according to the embodiment of the present application, the piezoelectric element 2 includes at least two connecting parts 22 with different polarities to facilitate the formation of a loop for the electrical connection of the piezoelectric element 2. At least two connecting parts 22 are arranged at the edge of the piezoelectric element 2, then it can facilitate the electrical connection of the piezoelectric element 2 with the relevant circuit and reduce the deformation interference of the electrical connection on the piezoelectric element 2.

[0085] For the convenience of the arrangement of the piezoelectric element 2, referring to Figure 6, in some possible embodiments of the present application, the piezoelectric member 2 and the connection area 12 are disposed on the same structural side 11. When the base body 1 is connected to the external member 7 through the connection area 12, the piezoelectric member 2 is located on the side of the base body 1 facing the external member 7; refer to Figure 3 and Figure 5 , in some other possible embodiments of the present application, the piezoelectric member 2 and the connection area 12 are respectively disposed on two structural sides 11. When the base body 1 is connected to the external member 7 through the connection area 12, the piezoelectric member 2 is located on the side of the base body 1 away from the external member 7.

[0086] For the electronic device according to the embodiment of the present application, the piezoelectric member 2 and the connection area 12 may be disposed on the same structural side 11, that is, the piezoelectric member 2 faces the external member 7, and the base body 1 is located outside the piezoelectric member 2, which can provide certain protection for the piezoelectric member 2; the piezoelectric member 2 and the connection area 12 may also be respectively disposed on two structural sides 11, that is, the piezoelectric member 2 is disposed away from the external member 7, which is convenient for the electrical connection of the piezoelectric member 2.

[0087] To save space and facilitate the transmission of vibration, refer to Figure 3 、 Figure 5 and Figure 6 , in some possible embodiments of the present application, the electronic device further includes a connecting member 3 disposed in the connection area 12; when the piezoelectric member 2 and the connection area 12 are respectively disposed on two structural sides 11, the dimension L1 of the connecting member 3 along the first direction X is greater than the amplitude L2 of the base body 1 along the first direction X; wherein, the first direction X is the vibration direction of the base body 1.

[0088] In the embodiment of the present application, the connecting member 3 may be a plate-like structure, a block-like structure, a rod-like structure, etc. The connection area 12 is the area on the base body 1 where the connecting member 3 is disposed, and one or more connecting members 3 may be disposed in each connection area 12. Exemplarily, the connecting member 3 is a cuboid structure, and one connecting member 3 is disposed in each connection area 12. Wherein, the connecting member 3 and the base body 1 may be integrally formed, or fixed by means of bonding, welding, clamping, fastener connection, etc.

[0089] It should be noted that the connection firmness of the connecting member 3 and the sufficiency of vibration transmission are positively correlated with the connection area of the connecting member 3, that is, under the condition of permission, the larger the connection area between the connecting member 3 and the base body 1, the firmer the connection between the connecting member 3 and the base body 1, and the more sufficient the connecting member 3 can transmit vibration.

[0090] In the embodiment of the present application, the connecting member 3 and the piezoelectric member 2 may be disposed with a gap along the extension direction of the structural side 11, that is, in the projection along the first direction X, there is a gap between the projection of the connecting member 3 and the projection of the piezoelectric member 2. The gap setting enables the base body 1 to have sufficient vibration space, so as to facilitate the connecting member 3 to transmit vibration to the external member 7 to improve the vibration effect.

[0091] It should be noted that the amplitude of the substrate 1 in the first direction X refers to the distance between the state where the substrate 1 is deformed and generates the maximum protrusion in the first direction X and the state where the substrate 1 is not deformed. For the schematic diagram of the maximum protrusion generated by the substrate 1 in the first direction X, please refer to Figure 3 the dashed-line structure in. The maximum protrusion generated by the substrate 1 in the first direction X is related to the elastic modulus of the substrate 1. Therefore, the size of the connecting member 3 can be designed with reference to the manufacturing material of the substrate 1, the driving force of the piezoelectric member 2, etc.

[0092] In the electronic device according to the embodiment of the present application, a connecting member 3 is provided in the connecting area 12, and the substrate 1 is connected to the external member 7 through the connecting member 3. Since the piezoelectric member 2 and the connecting area 12 are respectively provided on two structural sides 11, the setting of the connecting member 3 does not need to consider the thickness of the piezoelectric member 2 itself, reducing the size of the connecting member 3 in the vibration direction of the substrate 1, making the vibration transmission path shorter, thus facilitating the transmission of vibration between the substrate 1 and the external member 7 and reducing the loss of vibration during transmission.

[0093] For the convenience of arranging the electronic device, referring to Figure 4 、 Figure 5 and Figure 6 , in some possible embodiments of the present application, the electronic device further includes a conductive member 4, and the conductive member 4 is electrically connected to the piezoelectric member 2. The conductive member 4 can transmit a first electrical signal and a second electrical signal, that is, the conductive member 4 transmits the first electrical signal from the working circuit 5 to the piezoelectric member 2, or transmits the second electrical signal generated by the piezoelectric member 2 to the working circuit 5.

[0094] In the embodiment of the present application, the conductive member 4 may include a metal conductor and an insulating layer wrapped outside the metal conductor. The conductive member 4 can connect the metal conductor to the piezoelectric member 2 by means of welding, clamping, pressing, etc., so that the piezoelectric member 2 and the conductive member 4 are electrically connected.

[0095] It can be understood that when the piezoelectric member 2 is provided with a communication portion 22, the conductive member 4 is connected to the communication portion 22 to transmit the first electrical signal and the second electrical signal, and the conductive member 4 is made of a flexible material.

[0096] In the embodiment of the present application, the conductive member 4 may be provided with pins, that is, one end of the connecting wire (such as a metal conductor) of the conductive member 4 close to the piezoelectric member 2 forms a pin, and the pin of the conductive member 4 is connected to the corresponding communication portion 22 by means of welding, clamping, pressing, etc., so that the conductive member 4 is electrically connected to the corresponding communication portion 22. Among them, the corresponding communication portion 22 of the conductive member 4 means that when the conductive member 4 has multiple pins and the piezoelectric member 2 includes multiple communication portions 22 with different electrode polarities, the multiple pins of the conductive member 4 are connected to the multiple communication portions 22 in one-to-one correspondence.

[0097] In the embodiments of the present application, the conductive member 4 is made of a flexible material and can be freely bent and deformed. For example, the conductive member 4 can be a conductive thin sheet formed by tin oxide, indium oxide, gallium oxide, etc.; alternatively, the connecting wire of the conductive member 4 can be a metal foil formed by copper, silver, gold, aluminum, etc.; the insulating layer of the conductive member 4 can be a polyimide film, etc. For example, the conductive member 4 is a flexible printed circuit (FPC).

[0098] In the electronic device of the embodiments of the present application, by arranging the conductive member 4 to be connected to the communicating portion 22, the conductive member 4 can transmit a first electrical signal to drive the piezoelectric member 2 to vibrate, or transmit a second electrical signal to use the piezoelectric member 2 as a sensor, thereby realizing two different uses based on the same structure.

[0099] In addition, the conductive member 4 is made of a flexible material, so that the conductive member 4 can be freely bent, and the electronic device is less affected by the conductive member 4 during installation, which is more convenient for the layout of the electronic device.

[0100] To reduce the space occupation, referring to Figure 4 , in some possible embodiments of the present application, the size L3 of the conductive member 4 along the first direction X is smaller than its size L4 along the second direction Y. The first direction X is the vibration direction of the base 1, and the second direction Y is perpendicular to the first direction X.

[0101] In the embodiments of the present application, the size L3 of the conductive member 4 along the first direction X is smaller than its size L4 along the second direction Y. The second direction Y is the direction parallel to the structural side 11, so that the conductive member 4 presents a flattened structure. A plurality of connecting wires (for example, metal conductors in a flattened shape) can be arranged in the conductive member 4 to correspond to a plurality of communicating portions 22 on the piezoelectric member 2, and the plurality of connecting wires can be arranged in sequence along the second direction Y.

[0102] In the electronic device of the embodiments of the present application, by reducing the size of the conductive member 4 along the vibration direction of the base 1, the conductive member 4 is made thinner and lighter, and the space occupation of the conductive member 4 in the vibration direction of the base 1 is smaller, which also makes the overall electronic device thinner and lighter, facilitating layout and use.

[0103] Referring to Figure 4 、 Figure 5 and Figure 6, an embodiment of the present application provides an electronic device, which includes a substrate 1, a piezoelectric element 2, and a conductive member 4. The piezoelectric element 2 is attached to the substrate 1. The piezoelectric element 2 is configured to generate deformation in response to a first electrical signal or generate a second electrical signal in response to external vibration. The substrate 1 is configured to vibrate following the deformation of the piezoelectric element 2, or transmit external vibration to the piezoelectric element 2; the substrate 1 includes two oppositely arranged structural sides 11, and one of the structural sides 11 is provided with two connection regions 12, and the connection regions 12 are used to connect an external component 7; along the deformation direction of the piezoelectric element 2, the piezoelectric element 2 is located between the two connection regions 12; the conductive member 4 is connected to the piezoelectric element 2 to transmit the first electrical signal and the second electrical signal, and the dimension L3 of the conductive member 4 along the first direction X is smaller than its dimension L4 along the second direction Y, the first direction X is the vibration direction of the piezoelectric element 2, and the second direction Y is perpendicular to the first direction X.

[0104] In the embodiment of the present application, the settings of the substrate 1, the piezoelectric element 2, the connection region 12, the external structure, and the conductive member 4 can refer to the above embodiment, and will not be repeated here.

[0105] In the embodiment of the present application, the conductive member 4 can be connected to the piezoelectric element 2 by means of welding, clamping, pressing, etc. Since the conductive member 4 is relatively thin and light, in order to improve the connection strength between the conductive member 4 and the piezoelectric element 2 to improve the electrical connection stability between the two, a protective sleeve 6 can also be provided on the piezoelectric element 2. The protective sleeve 6 is fixedly connected to the position of the piezoelectric element 2 provided with a communication portion 22. The protective sleeve 6 can be provided with a clamping structure, a pressing structure, etc. When the conductive member 4 extends into the protective sleeve 6, the pressing structure presses the metal conductor of the conductive member 4 on the corresponding communication portion 22 and locks the conductive member 4 relative to the piezoelectric element 2 to reduce the possibility of accidental loosening of the conductive member 4.

[0106] For the electronic device of the embodiment of the present application, the substrate 1 provides an installation basis for the piezoelectric element 2, and the substrate 1 further includes two oppositely arranged structural sides 11, and one of the structural sides 11 is provided with a connection region 12, and the connection region 12 is used to connect to an external component 7. The substrate 1 can also vibrate following the deformation of the piezoelectric element 2, that is, the substrate 1 can transmit the vibration generated by the piezoelectric element 2 in response to the first electrical signal, and transmit the vibration to the external component 7 through the connection region 12. The substrate 1 can also transmit external vibration to the piezoelectric element 2, that is, receive external vibration through the connection region 12 and transmit the external vibration to the piezoelectric element 2 so that the piezoelectric element 2 generates a second electrical signal in response to the external vibration.

[0107] On this basis, the piezoelectric element 2 is attached to the substrate 1, so that the piezoelectric element 2 and the substrate 1 can vibrate synchronously to improve the vibration transmission effect, and along the deformation direction of the piezoelectric element 2, the piezoelectric element 2 is located between the two connection regions 12, that is, both ends of the substrate 1 are used to connect external components 7 to transmit vibration, and the substrate 1 does not have a free end, which is more conducive to vibration transmission.

[0108] In addition, the electronic device is further provided with a conductive member 4, which can transmit a first electrical signal to drive the piezoelectric member 2 to deform, or transmit a second electrical signal to use the piezoelectric member 2 as a sensor. Wherein, the dimension L3 of the conductive member 4 along the first direction X is smaller than its dimension L4 along the second direction Y, that is, the dimension of the conductive member 4 along the vibration direction of the base 1 is reduced, making the conductive member 4 thinner and lighter, and the space occupied by the conductive member 4 in the vibration direction of the base 1 is smaller, also making the overall electronic device thinner and lighter, facilitating layout and use.

[0109] Compared with the related art where the connection wire harness of the piezoelectric member 2 is unreasonably arranged, in the electronic device of the embodiment of the present application, the dimension of the conductive member 4 along the vibration direction of the base 1 is smaller, reducing the space occupied by the conductive member 4 in this direction. The flattened setting of the conductive member 4 makes the overall electronic device thinner and lighter, facilitating layout and use.

[0110] To improve the vibration effect, referring to Figure 3 、 Figure 5 and Figure 6 , in some possible embodiments of the present application, only one of the two structural sides 11 is provided with the piezoelectric member 2. In the electronic device of the embodiment of the present application, only one of the two structural sides 11 is provided with the piezoelectric member 2, and the piezoelectric member 2 has a good fitting consistency with the base 1 and is not interfered by other piezoelectric members 2, thereby improving the vibration effect.

[0111] To facilitate the setting of the piezoelectric member 2, referring to Figure 6 , in some possible embodiments of the present application, the piezoelectric member 2 and the connection area 12 are arranged on the same structural side 11. When the base 1 is connected to the external component 7 through the connection area 12, the piezoelectric member 2 is located on the side of the base 1 facing the external component 7, and the conductive member 4 is also located on the side of the base 1 facing the external component 7 and is connected to the piezoelectric member 2.

[0112] Referring to Figure 3 、 Figure 4 and Figure 5 , in some other possible embodiments of the present application, the piezoelectric member 2 and the connection area 12 are respectively arranged on two structural sides 11. When the base 1 is connected to the external component 7 through the connection area 12, the piezoelectric member 2 is located on the side of the base 1 away from the external component 7, and the conductive member 4 is also located on the side of the base 1 away from the external component 7 and is connected to the piezoelectric member 2.

[0113] In the electronic device of the embodiment of the present application, the piezoelectric member 2 can be arranged on the same structural side 11 as the connection area 12, that is, the piezoelectric member 2 faces the external component 7, and the base 1 is located outside the piezoelectric member 2, which can provide protection for the piezoelectric member 2; the piezoelectric member 2 can also be respectively arranged on two structural sides 11 with the connection area 12, that is, the piezoelectric member 2 is arranged away from the external component 7, facilitating the electrical connection of the piezoelectric member 2.

[0114] For the convenience of arranging the conductive member 4, with reference to Figure 6 and Figure 7 , in some possible embodiments of the present application, the piezoelectric member 2 includes a first edge 23 and a second edge 24. The extending direction of the first edge 23 is perpendicular to the deformation direction of the piezoelectric member 2. The second edge 24 is arranged adjacent to the first edge 23, and the second edge 24 is located between two first edges 23. When the piezoelectric member 2 and the connection region 12 are arranged on the same structural side 11, the conductive member 4 is connected to the second edge 24. It can be understood that the conductive member 4 is connected to the communication part 22 of the piezoelectric member 2. At this time, the communication part 22 of the piezoelectric member 2 and the conductive member 4 are correspondingly arranged on the second edge 24.

[0115] In the embodiments of the present application, the piezoelectric member 2 may include multiple edges along the extending direction of the structural side 11. For example, the piezoelectric member 2 is a cuboid structure, and its deformation direction is the length direction. The piezoelectric member 2 includes four edges along the extending direction of the structural side 11. Among them, the two edges on both sides of the length direction of the piezoelectric member 2 are close to the connection region 12, and the extending direction of this edge is perpendicular to the deformation direction of the piezoelectric member 2, which is the first edge 23 of the piezoelectric member 2. The two edges on both sides of the width direction of the piezoelectric member 2 are relatively far from the connection region 12 compared to the first edge 23, which is the second edge 24 of the piezoelectric member 2. That is, the edge of the piezoelectric member 2 adjacent to the connection region 12 and the edge of the piezoelectric member 2 where the conductive member 4 is located are different.

[0116] In some other embodiments, when the piezoelectric member 2 and the connection region 12 are arranged on the same structural side 11, the conductive member 4 may also be connected to the first edge 23. At this time, since the conductive member 4 is likely to interfere with the connecting member 3, the conductive member 4 can be arranged to pass through the connecting member 3 or be nested in the connecting member 3.

[0117] Among them, the extending direction of the first edge 23 is the direction where the extending trend of the first edge 23 is located, which is not a structural limitation on the first edge 23. Both the first edge 23 and the second edge 24 are areas close to the edge of the piezoelectric member 2. Among them, the edge corresponding to the first edge 23 can be a straight line, a broken line or an arc, etc. Correspondingly, the extending direction of the second edge 24 can be parallel to the deformation direction of the piezoelectric member 2, or can be arranged at an angle to the deformation direction of the piezoelectric member 2, and the edge corresponding to the second edge 24 can be a straight line, a broken line or an arc, etc.

[0118] It should be noted that when the piezoelectric member 2 and the connection region 12 are arranged on different structural sides 11, the conductive member 4 can be arranged on the first edge 23 or the second edge 24. The embodiments of the present application do not limit this.

[0119] In addition, the conductive member 4 is used to connect to the communication portion 22 of the piezoelectric member 2. The communication portion 22 can be provided on the first edge 23 or the second edge 24 corresponding to the conductive member 4. It should be noted that when multiple communication portions 22 are provided on the piezoelectric member 2, the spacing between the multiple communication portions 22 should be set to be small under process allowable conditions. On the one hand, the small spacing between the multiple communication portions 22 facilitates the connection of the multiple communication portions 22 with different electrode polarities to the conductive member 4, which is beneficial to reducing the size of the conductive member. On the other hand, when the multiple communication portions 22 are arranged parallel to the second edge 24, the spacing direction of the multiple communication portions 22 is the same as the deformation direction of the piezoelectric member 2, and the small spacing can reduce the influence of the communication portion 22 and the conductive member 4 on the deformation of the piezoelectric member 2.

[0120] In the electronic device according to the embodiment of the present application, the piezoelectric member 2 includes a first edge 23 and a second edge 24 arranged adjacent to each other. Since the piezoelectric member 2 is arranged between two connection regions 12, the extension direction of the first edge 23 can be perpendicular to the deformation direction of the piezoelectric member 2. The connection region 12 is arranged at a position of the substrate 1 close to the first edge 23 to be connected to the external component 7, which is not convenient for the layout of the conductive member 4. The conductive member 4 is arranged on the second edge 24 adjacent to the first edge 23, which is convenient for the conductive member 4 to be led out from the piezoelectric member 2 and is more convenient for the installation of the electronic device.

[0121] In order to improve the vibration effect and facilitate the electrical connection of the piezoelectric member 2, referring to Figure 5 and Figure 6 , in some possible embodiments of the present application, the piezoelectric member 2 includes at least two driving sheets 21, the at least two driving sheets 21 are stacked along the first direction X, and the at least two driving sheets 21 are electrically connected through the communication portion 22; the conductive member 4 is electrically connected to the communication portion 22.

[0122] In the embodiment of the present application, the settings of the driving sheet 21 and the communication portion 22 can refer to the above embodiment and will not be repeated here.

[0123] In the embodiment of the present application, the conductive member 4 is electrically connected to the communication portion 22. Specifically, one end of the connection line (such as a metal conductor) of the conductive member 4 close to the communication portion 22 is exposed relative to the insulating layer, thereby forming a pin, and the pin is connected to the corresponding communication portion 22 by means of welding, pressing, etc., so as to electrically connect the communication portion 22 and the conductive member 4.

[0124] In the electronic device according to the embodiment of the present application, the piezoelectric member 2 may include two or more driving sheets 21. Each driving sheet 21 can generate deformation under the action of an electric field. Since a plurality of driving sheets 21 are stacked in sequence in a direction away from the base body 1, that is, stacked in sequence along the vibration direction of the base body 1, the deformation forces of two or more driving sheets 21 can be superimposed on each other to drive the base body 1 to generate a more powerful vibration, such as increasing the amplitude of the base body 1, etc., thereby improving the vibration effect. The piezoelectric member 2 is provided with a connecting portion 22 to electrically connect at least two driving sheets 21 through the connecting portion 22. It is only necessary to electrically connect the connecting portion 22 to the relevant circuit, and the structure is simpler, and it is also convenient for the fitting arrangement of a plurality of driving sheets 21.

[0125] For the convenience of the electrical connection of the piezoelectric member 2, referring to Figure 2 、 Figure 9 and Figure 10 in some possible embodiments of the present application, the piezoelectric member 2 includes at least two connecting portions 22, and at least two connecting portions 22 correspond to different polarities, and at least two connecting portions 22 are arranged at the edge of the piezoelectric member 2.

[0126] In the embodiment of the present application, the polarity of the connecting portion 22 can be determined by the working mode of the connecting portion 22, that is, the connecting portion 22 is provided with a positive connecting portion 22 and a negative connecting portion 22. The positive connecting portion 22 needs to be connected to the positive pole of the working circuit 5, and the negative connecting portion 22 needs to be connected to the negative pole of the working circuit 5. In addition, the polarity of the connecting portion 22 can also be determined by the polarity of the working circuit 5. For details, reference can be made to the above embodiments regarding the first connecting portion 22a and the second connecting portion 22b.

[0127] It should be noted that the piezoelectric member 2 is connected to the working circuit 5 through the conductive member 4. When each piezoelectric member 2 includes at least two connecting portions 22 and at least two connecting portions 22 correspond to different polarities, the conductive member 4 should also be provided with at least two mutually insulated connecting wires (for example, metal conductors). The ends of the connecting wires (for example, metal conductors) away from the working circuit 5 form pins, and the pins of each connecting wire (for example, metal conductor) are correspondingly connected to a connecting portion 22.

[0128] In the electronic device according to the embodiment of the present application, the piezoelectric member 2 includes at least two connecting portions 22 with different polarities to facilitate the electrical connection of the piezoelectric member 2 to the working circuit 5 to form a loop. At least two connecting portions 22 are arranged at the edge of the piezoelectric member 2, which can facilitate the electrical connection between the piezoelectric member 2 and the working circuit 5 and reduce the interference of the electrical connection on the deformation generated by the piezoelectric member 2.

[0129] For improving the vibration effect and facilitating the electrical connection of the conductive member 4, referring to Figure 8 、 Figure 9 and Figure 10, in some possible embodiments of the present application, piezoelectric elements 2 are provided on both structural sides 11. The conductive member 4 includes a joint portion 43 and two conductive portions extending from the joint portion 43 toward the two structural sides 11 respectively, and each conductive portion is connected to the piezoelectric element 2 on the corresponding structural side 11.

[0130] In the embodiment of the present application, the joint portion 43 extends toward the two structural sides 11 respectively. It can be understood that the two conductive members 4 converge at the joint portion 43. Specifically, the connecting lines of the two conductive portions (such as metal conductors) can be connected at the joint portion 43 by welding or pressing. With such a setting, a standardized connection interface can be provided at the joint portion 43 to facilitate the connection between the conductive member 4 and the working circuit 5.

[0131] It should be noted that when the piezoelectric element 2 includes multiple communicating portions 22, each conductive portion is also provided with multiple connecting lines (such as metal conductors). When the connecting lines of the two conductive portions are electrically connected at the joint portion 43, the electrode polarities should be kept corresponding so that the deformation directions generated simultaneously by the piezoelectric elements 2 on the two structural sides under the action of the electric field are opposite (for example, the piezoelectric element 2 on one side undergoes an expansion deformation, and the piezoelectric element 2 on the other side undergoes a contraction deformation). Among them, the connecting line of each conductive portion can only be connected to another connecting line in a different conductive portion, and cannot be connected to the connecting line in the same conductive portion.

[0132] In the embodiment of the present application, when two piezoelectric elements 2 are provided and the two piezoelectric elements 2 are arranged opposite to each other, it is also possible that the two piezoelectric elements 2 are respectively electrically connected to the working circuit 5 through the conductive member 4, that is, the number and connection of the conductive member 4 and the piezoelectric element 2 are set in one-to-one correspondence.

[0133] In the electronic device according to the embodiment of the present application, piezoelectric elements 2 are provided on both structural sides 11 of the base body 1. The interaction between the two piezoelectric elements 2 can provide a more powerful vibration to improve the vibration effect. The conductive member 4 includes a joint portion 43 and two conductive portions extending from the joint portion 43 toward the two structural sides 11 respectively, and each conductive portion is connected to the piezoelectric element 2 on the corresponding structural side 11, so that the conductive member 4 can synchronously transmit the first electrical signal or the second electrical signal with the two piezoelectric elements 2. Compared with setting two conductive members 4, the structure is also simpler.

[0134] To meet the different layout requirements of the conductive member 4, refer to Figure 9 and Figure 10, in some possible embodiments of the present application, each piezoelectric element 2 includes two connecting portions 22, and the two connecting portions 22 correspond to different polarities. Each conductive portion includes two connecting wires for connecting to the two connecting portions 22 of each corresponding piezoelectric element 2 one by one; and corresponding to the polarity of the connecting portion 22 to which the connecting wire is connected, the connecting wires of the two conductive portions are connected according to different polarities at the joint portion 43, so that the piezoelectric elements 2 on both sides of the substrate generate deformations in opposite directions in response to the first electrical signal.

[0135] In the embodiments of the present application, the connecting portions 22 of the two piezoelectric elements 2 can be arranged oppositely along the first direction X, which facilitates the electrical connection of the conductive member 4 to the two piezoelectric elements 2 respectively. On this basis, the polarities of the connecting portions 22 arranged on both sides of the substrate 1 along the first direction X can be the same or different.

The pin is used to be welded, pressed, etc. with the corresponding connection portion 22 to electrically connect the two.

[0142] Refer to Figure 9 、 Figure 10 、 Figure 11 and Figure 13 , in some possible embodiments of the present application, the first conductive portion 41 includes a first connection line 411 and a second connection line 412, and the second conductive portion 42 includes a third connection line 421 and a fourth connection line 422. Among them, the first connection line 411 is connected to the first connection portion 22a, and the third connection line 421 and the first connection line 411 are respectively connected to the positive connection portions 22 of the two piezoelectric members 2, and the second connection line 412 and the fourth connection line 422 are respectively connected to the negative connection portions 22 of the two piezoelectric members 2.

[0143] On this basis, the conductive member 4 can include a first conductive portion 41 and a second conductive portion 42. The first conductive portion 41 includes a first connection line 411 and a second connection line 412. The first connection line 411 is connected to the first connection portion 22a, and the second connection line 412 is connected to the second connection portion 22b; the second conductive portion 42 includes a third connection line 421 and a fourth connection line 422. The third connection line 421 is connected to the third connection portion 22c, and the fourth connection line 422 is connected to the fourth connection portion 22d. It can be understood that corresponding to the polarities of the first connection portion 22a and the third connection portion 22c, both the first connection line 411 and the third connection line 421 correspond to the positive pole; corresponding to the polarities of the second connection portion 22b and the fourth connection portion 22d, both the second connection line 412 and the fourth connection line 422 correspond to the negative pole.

[0144] Refer to Figure 9 、 Figure 11 and Figure 12, in some possible embodiments of the present application, the first connection part 22a and the fourth connection part 22d are opposite to each other along the first direction X, and the second connection part 22b and the third connection part 22c are opposite to each other along the first direction X, that is, the connection parts 22 with different electrode polarities are arranged oppositely.

[0145] Referring to Figure 9 and Figure 11 , in a possible embodiment of the present application, the first connection part 22a is arranged in the first region 25 of the piezoelectric element 2 on one side of the base body 1, the second connection part 22b is arranged in the second region 26, the fourth connection part 22d is arranged in the first region 25 of the piezoelectric element 2 on the other side of the base body, and the third connection part 22c is arranged in the second region 26; referring to Figure 9 and Figure 12 , in another possible embodiment of the present application, the first connection part 22a is arranged in the first region 25 of the piezoelectric element 2 on one side of the base body 1, the second connection part 22b is arranged in the second region 26, the third connection part 22c is arranged in the first region 25 of the piezoelectric element 2 on the other side of the base body, and the fourth connection part 22d is arranged in the second region 26. It should be noted that Figure 11 , Figure 12 , Figure 13 and Figure 14 are schematic diagrams of the electrical connection relationship between the first conductive part 41 and the second conductive part 42. For the convenience of representation, the two piezoelectric elements 2 on the opposite sides of the base body 1 in the figure are unfolded to the same plane, and the connection structure between the joint part 43 and the working circuit 5 is not shown. Therefore, it should not be regarded as a structural limitation of the electronic device of the present application.

[0146] On this basis, the first connection line 411 and the fourth connection line 422 are connected at the joint part 43, and the second connection line 412 and the third connection line 421 are connected at the joint part 43. Since the polarities of the connection parts 22 opposite to each other along the first direction X are different, the connection lines can be arranged in parallel at the position of the joint part 43.

[0147] Referring to Figure 10 , Figure 13 and Figure 14 , in some other possible embodiments of the present application, the first connection part 22a and the third connection part 22c are opposite to each other along the first direction X, and the second connection part 22b and the fourth connection part 22d are opposite to each other along the first direction X, that is, the connection parts 22 with the same electrode polarity are arranged oppositely.

[0148] Referring to Figure 10 and Figure 13 , in a possible embodiment of the present application, the first connection part 22a is arranged in the first region 25 of the piezoelectric element 2 on one side of the base body 1, the second connection part 22b is arranged in the second region 26, the third connection part 22c is arranged in the first region 25 of the piezoelectric element 2 on the other side of the base body, and the fourth connection part 22d is arranged in the second region 26.

[0149] Reference Figure 10 and Figure 14 In another possible embodiment of the present application, a second communication part 22b is provided in the first region 25 of the piezoelectric member 2 on one side of the substrate 1, and a first communication part 22a is provided in the second region 26. A third communication part 22c is provided in the first region 25 of the piezoelectric member 2 on the other side of the substrate, and a fourth communication part 22d is provided in the second region 26.

[0150] It can be understood that since the polarities of the communication parts 22 opposite to each other along the first direction X are the same, in order to ensure that the deformation directions of the piezoelectric sheets 2 on both sides are opposite under the action of the electric field, the connection lines need to be crossed at the joint part 43. Specifically, the first connection line 411 and the fourth connection line 422 are connected, and the second connection line 412 and the third connection line 421 are connected. At the joint part 43, the connection line of the first connection line 411 and the fourth connection line 422 intersects the connection line of the second connection line 412 and the third connection line 421.

[0151] In the electronic device according to the embodiment of the present application, the two connection lines of the conductive part are connected to the two communication parts 22 of the piezoelectric member 2 in a one-to-one correspondence, and corresponding to the electrode polarities of the communication parts 22 connected by the connection lines, the connection lines of the two conductive parts are connected with the same polarity at the joint part 43, so that various layouts can be adopted for the connection lines in the two conductive parts. Among them, when the polarities of the connection lines relatively arranged on both sides of the substrate 1 are different, it is more convenient for the conductive parts to be combined at the joint part 43.

[0152] In order to facilitate the layout of the electronic device, in some possible embodiments of the present application, the conductive member 4 is made of a flexible material. The flexible material can refer to the above embodiments and will not be repeated here.

[0153] In the electronic device according to the embodiment of the present application, the conductive member 4 is made of a flexible material, so that the conductive member 4 can be bent freely, and the electronic device is less affected by the conductive member 4 during installation, which is more convenient for the layout of the electronic device.

[0154] Reference Figure 15 In some possible embodiments of the present application, at least two piezoelectric members 2 are provided, and each piezoelectric member 2 includes at least two communication parts 22 with different electrode polarities. The conductive member 4 includes at least two wires 44. The wire 44 includes a total wire segment 441 and at least two sub-wire segments 442 extending from the total wire segment 441. At least two sub-wire segments 442 of the same wire 44 are respectively connected to the communication parts 22 with the same electrode polarity in at least two piezoelectric members 2.

[0155] In the embodiment of the present application, each piezoelectric element 2 may include a connecting portion 22 of positive polarity and a connecting portion 22 of negative polarity. In this case, the conductive element 4 includes two wires 44, one of the two wires 44 connects all the connecting portions 22 of positive polarity in at least two piezoelectric elements 2, and the other of the two wires 44 connects all the connecting portions 22 of negative polarity in at least two piezoelectric elements 2.

[0156] In the embodiment of the present application, the number of branch wire segments 442 included in each wire 44 can be two, three, four, etc., which can be specifically set according to the number of piezoelectric elements 2 and the number of connecting parts 22 on a single piezoelectric element 2. For example, there are three piezoelectric elements 2, and each piezoelectric element 2 includes a connecting part 22 of a positive electrode polarity and a connecting part 22 of a negative electrode polarity, and correspondingly, each wire 44 includes three branch wire segments 442; or, there are two piezoelectric elements 2, and each piezoelectric element 2 includes two connecting parts 22 of a positive electrode polarity and a connecting part 22 of a negative electrode polarity, and correspondingly, the wire 44 connecting the connecting part 22 of the positive electrode polarity includes four branch wire segments 442, and the wire 44 connecting the connecting part 22 of the negative electrode polarity includes two branch wire segments 442, so that the branch wire segments 442 of different wires 44 are correspondingly connected to the connecting parts 22 of different electrode polarities.

[0157] In the embodiment of the present application, there is no limit on the length of the wire 44. The wire 44 is relatively long and can be extended to a longer distance to facilitate the layout of the piezoelectric element 2. The wire 44 is relatively short, and the energy loss during signal transmission is small, the transmission time is short, and it is more convenient for signal transmission. For example, the length of the branch wire segment 442 can be 6cm (curium, centimeters), 7cm, 10cm, etc., and the length of the total wire segment 441 can be 65cm, 70cm, 80cm, etc., which can be set according to actual needs.

[0158] In addition, the wire 44 includes a metal conductor for signal transmission, and the periphery of the metal conductor may be wrapped with an insulating layer and / or a shielding layer to protect the metal conductor or reduce external interference.

[0159] In the electronic device of the embodiment of the present application, at least two connecting portions 22 of the same electrical polarity in each piezoelectric element 2 are connected to the same main wire segment 441 through at least two branch wire segments 442 to concentrate the branch wire segments 442 of the same electrical polarity, thereby facilitating the arrangement and connection of the wires 44.

[0160] To facilitate further organization of the wire 44 , the multiple branch wire segments 442 in the embodiment of the present application can be gathered together by means of wire gathering, bundling, wrapping, etc.

[0161] Reference Figure 15, in some possible embodiments of the present application, the conductive member 4 further includes at least two wire gathering portions 45, and the region where the total wire segment 441 and the sub-wire segments 442 in the same wire 44 are connected is disposed within the corresponding wire gathering portion 45.

[0162] In the embodiments of the present application, the multiple sub-wire segments 442 in the same wire 44 are gathered together through the wire gathering portion 45 to form the total wire segment 441. And the number of the wire gathering portions 45 is the same as the number of the wires 44, so that the multiple sub-wire segments 442 of each wire 44 are gathered together through the same wire gathering portion 45.

[0163] In the embodiments of the present application, the wire gathering portion 45 is used to gather all the sub-wire segments 442 with corresponding electrode polarities, and the structure of the wire gathering portion can be a snap-on type, a press-fitting type, a connecting sleeve, etc.

[0164] In the electronic device of the embodiments of the present application, by providing the wire gathering portion 45, the total wire segment 441 and the sub-wire segments 442 in the same wire 44 are bundled in the wire gathering portion 45, and are limited and fixed together by the wire gathering portion 45, with a simple structure and facilitating the centralized layout of the wire 45.

[0165] Refer to Figure 16 , in some possible embodiments of the present application, the wire gathering portion 45 includes two oppositely disposed connecting plates 451, an accommodation space 452 is formed between the two connecting plates 451, and the first side edges 453 of the two connecting plates 451 facing each other are connected to each other. In the first state of the wire gathering portion 45, the second side edges 454 of the two connecting plates 451 facing each other are separated from each other to form an opening, and the opening is used for the corresponding wire 44 to pass through and enter the accommodation space 452. In the second state of the wire gathering portion 45, the second side edges 454 of the two connecting plates 451 are abutted against each other to close the opening. Wherein, the first side edge 453 and the second side edge 454 are oppositely disposed.

[0166] In the embodiments of the present application, the first side edges 453 of the two connecting plates 451 facing each other can be connected together by means of movable connection (such as hinge connection, flexible connection, etc.), integral molding, etc. Refer to Figure 16 , in a possible embodiment of the present application, the connecting plate 451 is made of a material with relatively high toughness, that is, a material that can deform under an external force and is not easily damaged, such as copper.

[0167] In order to form the accommodation space 452 between the two connecting plates 451, the first side edges 453 of the two connecting plates 451 facing each other can be bent or folded, for example, refer to Figure 16 , the first side edges 453 of the two connecting plates 451 facing each other are bent and connected to each other, so that the cross-sectional shape of the wire gathering portion 45 along the direction perpendicular to the first side edge 453 is in a "U" shape.

[0168] On this basis, when the wire collecting part 45 collects each sub-wire segment 442 and the corresponding main wire segment 441, with reference to Figure 16 , the wire collecting part 45 is in the first state, that is, the second side edges 454 opposite to each other of the two connecting plates 451 are far away from each other to form an opening, and both the main wire segment 441 and the corresponding sub-wire segment 442 are put into the accommodating space 452 through the opening. When a wire 44 is placed in the accommodating space 452, the second side edges 454 opposite to each other of the two connecting plates 451 approach each other and abut against each other to close the opening, that is, the wire collecting part 45 is in the second state, and then the corresponding sub-wire segment 442 and the main wire segment 411 are concentrated and constrained together. In this process, the wire 44 can be quickly put into the accommodating space 452 from the opening position, and the operation is more convenient.

[0169] In the electronic device according to the embodiment of the present application, the wire collecting part 45 forms an accommodating space 452, which can be used to accommodate and constrain the wire harness 44, and an opening is formed by the second side edges 454 opposite to each other of the two connecting plates 451 in the wire collecting part 45, and the wire 44 can be quickly put in through the opening. Compared with putting the wire 44 into the wire collecting part 45 from both ends, it is more convenient and can improve the wire collecting efficiency.

[0170] In addition, the wire collecting part 45 may not be provided with an opening. For example, the wire collecting part 45 is arranged as a sleeve structure. When the wire 44 is put into the wire collecting part 45, the sleeve structure is pressed together to concentrate and constrain the main guiding segment 441 and the sub-wire segment 442 of the wire 44.

[0171] With reference to Figure 17 , in some possible embodiments of the present application, at least one connecting part 443 is arranged on the main wire segment 441, and adjacent main wire segments 441 are connected together through the connecting part 443. With reference to Figure 15 , in some other possible embodiments of the present application, at least two main wire segments 441 are spirally wound together.

[0172] In the embodiment of the present application, the number of the connecting parts 443 arranged on each main wire segment 441 can be one or more, and when the number of the connecting parts 443 is set to be multiple, the multiple connecting parts 443 are arranged at intervals along the length direction of the main wire segment 441.

[0173] In the embodiment of the present application, the connecting part 443 can be in the form of a buckle, a wire buckle, a magnet, etc., and the present application does not make specific limitations thereto. By way of example, the connecting part 443 is a buckle, and the buckle includes two clamping grooves, and the two clamping grooves respectively clamp and fix two adjacent main wire segments 441.

[0174] In the embodiment of the present application, at least two main wire segments 441 can be wound together in a single helix or in a multi-helix manner. Taking two main wire segments 441 as an example, the winding method of the single helix is ​​that one main wire segment 441 extends linearly, and the other main wire segment 441 is helically wound on the linearly extended main wire segment 441; the winding method of the double helix is ​​that the two main wire segments 441 extend helically around each other, for example Figure 15 shown.

[0175] In the electronic device of the embodiment of the present application, each main wire segment 441 is connected or spirally wound together by a connecting portion 443, which can constrain multiple main wire segments 441, thereby making each wire 44 more orderly, facilitating the layout of the wire 44, and at the same time helping to improve signal transmission performance and anti-interference capabilities.

[0176] Reference Figure 15 In some possible embodiments of the present application, the conductive member 4 further includes a first connector 46, and one end of at least two main conductor segments 441 away from the line collection portion 45 is connected to the first connector 46, and the first connector 46 is used to connect to an external working circuit.

Correspondingly, the working circuit is provided with a second connector, and the first connector can be plugged and matched with the second connector. The structure of the first connector 46 can be set according to actual needs, and this embodiment does not make any specific limitations on this.

[0178] In the embodiment of the present application, at least two connection positions with different electrical polarities are provided on the first plug portion 46, which are used to respectively connect the main wire segments 441 with different electrical polarities. Figure 15 In one example, two main conductor segments 441 are provided, and the two main conductor segments 441 have a positive electrode polarity and a negative electrode polarity respectively. At this time, the first connector 46 is provided with two connection positions, namely a positive electrode connection position and a negative electrode connection position. The positive electrode connection position is connected to the main conductor segment 441 having a positive electrode polarity, and the negative electrode connection position is connected to the main conductor segment 441 having a negative electrode polarity.

[0179] In the electronic device of the embodiment of the present application, the setting of the first connector 46 enables the end of each main wire segment 441 away from the collection part 45 to be centrally connected to the first connector 46, and is connected to an external working circuit through the first connector 46 to facilitate the connection between the wire 44 and the external working circuit, and the plug-in setting has the advantage of easy maintenance.

[0180] Reference Figure 18 In some possible embodiments of the present application, the electronic device further includes a seal 8 , which is sealingly disposed on the periphery of at least one line collection portion 45 .

[0181] Referring to Figure 18 , in one example, a seal 8 is respectively and hermetically arranged on the outer periphery of each wire gathering part 45.

[0182] In the embodiment of the present application, the seal 8 hermetically wraps the outer periphery of the wire gathering part 45, and the seal 8 is made of a waterproof insulating material, such as rubber, plastic, etc. The seal 8 contracts inward along the radial direction of the wire gathering part 45 at both axial ends of the wire gathering part 45 to wrap the branch wire segments 442 and the main wire segment 441 located at both ends of the wire gathering part 45, so that the seal 8 can protect the wire gathering part 45 and the branch wire segments 442 and the main wire segment 441 located at both ends of the wire gathering part 45. Moreover, the wire gathering parts 45 provided with the seals 8 can also be stacked together and integrally wrapped to form a wire gathering part set, so as to centrally constrain a plurality of wire gathering parts 45.

Exemplarily, the seal 8 is arranged as a sealing ring, the first plugging part 46 is arranged as a female plug with a jack on the plugging end 461, the seal 8 is embedded at a position on the inner wall of the jack on the plugging end 461, and is hermetically adapted to the mating end of the second plugging part arranged as a male plug.

[0184] In the embodiment of the present application, the seal 8 can be arranged at the plugging end 461 of the first plugging part 46 to improve the sealing performance between the plugging end 461 of the first plugging part 46 and the second plugging part of the working circuit; the seal 8 can also be arranged at the position where the first plugging part 46 is connected to each main wire segment 441, so as to improve the sealing performance of the connection between the first plugging part 46 and a plurality of main wire segments 441.

In some embodiments, the electronic device can be connected to the vehicle body and electrically connected to the vehicle-mounted terminal, and the vehicle-mounted terminal serves as a controller of the working circuit 5.

[0188] The vehicle according to the embodiment of the present application includes the electronic device according to the embodiment of the present application. Therefore, when the electronic device is connected to the vehicle body 9, only one of the two structural sides 11 of the base body 1 is provided with the piezoelectric element 2, reducing the influence of the process defects of the piezoelectric element 2 on the performance of the electronic device, improving the vibration effect, and the size of the conductive member 4 along the vibration direction of the base body 1 is small, reducing the space occupied by the conductive member 4 in this direction. The flattened setting of the conductive member 4 makes the overall electronic device thinner and lighter, facilitating layout and use.

[0189] Referring to Figure 1 、 Figure 4 、 Figure 5 and Figure 20 In a possible embodiment of the present application, the electronic device is mounted on the vehicle body sheet metal. The electronic device can be used as a sounding device or a sensor. Specifically, the electronic device includes a base body 1, and two connecting members 3 are provided on one side of the base body 1. The base body 1 is bonded to the vehicle body sheet metal through the connecting members 3.
