Smart devices can include various portable computer programs. For example, access control devices, camera devices, smart home appliances, smart terminals, etc.
[0034] In some technical solutions, the interactive device is provided with a sound emitting component, but due to the limitation of the connection mode, the high frequency consistency of the sound emitting component is insufficient, and it is difficult to achieve effective output.
[0035] 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 first vibrating piece, reduces the influence of the first connecting piece and the external component on the first vibrating piece, and can provide better medium and low frequency response; the second connecting piece is fully attached, the vibration amplitude is small, and high frequency vibration is easy to produce, and the high frequency response is better. The combination of the first sound emitting component and the second sound emitting component can not only maintain good high frequency sound emission, but also provide excellent medium and low frequency sound emission capability, thereby improving the user's experience.
[0036] Reference Figure 1 and Figure 2 The interactive device of the embodiments of the present application includes a first sound emitting component 100 and a second sound emitting component 200, the first sound emitting component 100 includes a first vibrating piece 110 and a first connecting piece 120 connected with each other, and the first connecting piece 120 is arranged corresponding to the outer edge of the first vibrating piece 110; the second sound emitting component 200 includes a second vibrating piece 210 and a second connecting piece 220 connected with each other; wherein the first vibrating piece 110 and the second vibrating piece 210 are used for vibrating sound emission, and the first connecting piece 120 and the second connecting piece 220 are used for connecting an external component 400 to transmit vibration.
[0037] In the embodiments of the present application, the first vibrating piece 110 can be a piezoelectric piece, a magnetostrictive piece, etc., and the second vibrating piece 210 can also be a piezoelectric piece, a magnetostrictive piece, etc. The second vibrating piece 210 and the first vibrating piece 110 can adopt the same or different structure forms. For example, the first vibrating piece 110 and the second vibrating piece 210 are both piezoelectric pieces, and the first vibrating piece 110 and the second vibrating piece 210 can vibrate and emit sound under the action of current by using the inverse piezoelectric effect, to be used as a loudspeaker.
[0038] In the embodiment of the present application, the first connecting piece 120 is used to connect the first vibrating piece 110 to the external component 400, and the first connecting piece 120 can be a buckle structure, a screw structure, an adhesive structure, etc. For example, the first connecting piece 120 is double-sided adhesive tape provided with an adhesive layer on both sides, and the opposite sides of the first connecting piece 120 are respectively bonded to the first vibrating piece 110 and the external component 400.
[0039] In the embodiment of the present application, the first connecting piece 120 is arranged corresponding to the outer edge of the first vibrating piece 110, that is, the middle part of the first vibrating piece 110 is left empty and the first connecting piece 120 is not arranged thereon, so as to reduce the influence of the first connecting piece 120 and the external component 400 on the first vibrating piece 110, so that the vibration deformation is more sufficient and a vibration with a larger amplitude can be generated, thereby providing a better mid-low frequency response.
[0040] In the embodiment of the present application, the second connecting piece 220 is used to connect the second vibrating piece 210 to the external component 400, and the second connecting piece 220 and the first connecting piece 120 can adopt the same or different structures. The second connecting piece 120 can be left empty in the middle part to form a ring shape, or can be attached to the second vibrating piece 210 on the whole surface. For example, the second connecting piece 220 is double-sided adhesive tape provided with an adhesive layer on both sides, and the opposite sides of the second connecting piece 220 are respectively bonded to the second vibrating piece 210 and the external component 400.
[0041] In the embodiment of the present application, the second connecting piece 220 is attached to the second vibrating piece 210 on the whole surface, and the second vibrating piece 210 acts on the external component 400 to generate a vibration with a smaller amplitude, which is easy to generate a high-frequency vibration and has a good high-frequency response.
[0042] It should be noted that the material of the first connecting piece 120 and the second connecting piece 220 has an influence on the transmission of vibration. A relatively soft material has a weakening effect on vibration and 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 piece 120 adopts a hard glue material, and the second connecting piece 220 adopts a soft glue material.
[0043] The technical scheme of the embodiment of the present application is that the first sound generating assembly 100 generates a mid-low frequency vibration through the first vibrating piece 110 and transmits the vibration to the external component 400 through the first connecting piece 120 to drive the external component 400 to vibrate and generate sound; and the second sound generating assembly 200 generates a high-frequency vibration through the second vibrating piece 210 and transmits the vibration to the external component 400 through the second connecting piece 220 to drive the external component 400 to vibrate and generate sound.
[0044] On this basis, the first connecting piece 120 is arranged at the outer edge of the first vibrating piece 110, the influence of the first connecting piece 120 and the external component 400 on the first vibrating piece 110 is reduced, and better medium-low frequency response can be provided; the second connecting piece 220 is attached to the second vibrating piece 210 in the whole surface, the vibration amplitude is smaller, high frequency vibration is easy to generate, and good high frequency response is obtained. The first sound generating assembly 100 and the second sound generating assembly 200 are combined, the good high frequency sound generation can be maintained, and excellent medium-low frequency sound generation capability can be provided, and then the use experience of the user is improved.
[0045] It should be noted that the first vibrating piece 110 can expand / contract along the length direction, the width direction or the radial direction, so as to vibrate along the thickness direction, the plane where the length direction, the width direction or the radial direction of the first vibrating piece 110 is located is the extension plane of the first vibrating piece 110, and the vibration direction of the first vibrating piece 110 is the thickness direction; correspondingly, the second vibrating piece 210 also expands / contracts along the length direction, the width direction or the radial direction, so as to vibrate along the thickness direction, the plane where the length direction, the width direction or the radial direction of the second vibrating piece 210 is located is the extension plane of the second vibrating piece 210, and the vibration direction of the second vibrating piece 210 is the thickness direction.
[0046] In the embodiment of the application, the vibration direction of the first vibrating piece 110 and the vibration direction of the second vibrating piece 210 can be parallel or at an angle, the extension plane of the first vibrating piece 110 and the extension plane of the second vibrating piece 210 can be parallel or at an angle, and the first vibrating piece 110 and the second vibrating piece 210 can be arranged on the same or different external components 400.
[0047] Referring to Figure 1 and Figure 2 In a possible embodiment of the application, the first vibrating piece 110 and the second vibrating piece 210 are arranged on the same structure surface of the same external component 400, the extension plane of the first vibrating piece 110 is parallel to the extension plane of the second vibrating piece 210, and correspondingly, the vibration direction of the first vibrating piece 110 is also parallel to the vibration direction of the second vibrating piece 210.
[0048] In the embodiment of the application, the shape of the first vibrating piece 110 along the extension plane can be square, diamond, triangle, hexagon, circle, ellipse and the like, and the shape of the second vibrating piece 210 along the extension plane can also be square, diamond, triangle, hexagon, circle, ellipse and the like. The shapes of the second vibrating piece 210 and the first vibrating piece 110 can be the same or different.
[0049] In an example, the first vibrating member 110 is a rectangular structure, and the second vibrating member 210 is a circular structure; in another example, the first vibrating member 110 is a circular structure, and the second vibrating member 210 is a square structure; in yet another example, the first vibrating member 110 and the second vibrating member 210 are both circular structures.
[0050] It should be noted that the first vibrating member 110 has a first area along its extension plane, and the second vibrating member 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 vibrating member 110 has a larger first area, and has a stronger driving force for vibration, and can generate vibration with a larger amplitude, and obtain good mid-low frequency response; the second vibrating member 210 has a smaller second area, and is more likely to generate high-frequency vibration under the limitation of the external member 400, and has better high-frequency response.
[0051] In order to improve the sound 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., and optionally, the second area of the second vibrating member 210 is smaller than the first area of the first vibrating member 110.
[0052] 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 make the first vibrating member 110 obtain good mid-low frequency sound performance, and can make the second vibrating member 210 obtain good high-frequency sound performance, and is helpful to improve the performance balance of the interactive device.
[0053] In some possible embodiments of the present application, the first vibrating member 110 is a rectangular structure, and the long side dimension of the first vibrating member 110 is 85 mm, and the short side dimension is 35 mm; the second vibrating member 210 is a square or circular structure, and the side length or diameter of the second vibrating member 210 ranges from 20 mm to 40 mm, for example, the second vibrating member 210 is circular, and the diameter is 20 mm, 30 mm, 40 mm, etc.
[0054] It should be noted that, in the case where the first vibrating member 110 and the second vibrating member 210 are arranged on the same structure surface of the outer member 400, the first vibrating member 110 and the second vibrating member 210 can be stacked along the vibration direction, in other words, the projection of the second vibrating member 210 along the vibration direction of the first vibrating member 110 can overlap or partially overlap the projection of the first vibrating member 110. Alternatively, the first vibrating member 110 and the second vibrating member 210 can be arranged at intervals along the structure surface of the outer member 400, in other words, the projection of the first vibrating member 110 along the vibration direction of the first vibrating member 110 can not overlap the projection of the second vibrating member 210. It can be understood that, in the case where the projections do not overlap, the outer edge of the first vibrating member 110 and the outer edge of the second vibrating member 210 have an interval size W10 along the extension plane. The larger the interval size W10, the smaller the mutual influence between the first sound generating assembly 100 and the second sound generating assembly 200, which is conducive to improving the performance of each other; the smaller the interval size W10, the smaller the space occupied by the interaction device, which is conducive to miniaturization and facilitates arrangement.
[0055] 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.
[0056] In the embodiments of the present application, in the case where the projections of the first vibrating member 110 and the second vibrating member 210 along the vibration direction overlap, the projection of the geometric center of the first vibrating member 110 and the projection of the geometric center of the second vibrating member 210 can overlap or not overlap; for example, the projection of the geometric center of the first vibrating member 110 and the projection of the geometric center of the second vibrating member 210 can overlap.
[0057] With reference to Figure 3 In some possible embodiments of the present application, in the case where the projections of the first vibrating member 110 and the second vibrating member 210 along the vibration direction overlap, the second vibrating member 210 can be spaced apart from the first connecting member 120 along the extension direction to reduce the mutual influence between the first vibrating member 110 and the second vibrating member 210.
[0058] It can be understood that, in the case where the projection of the geometric center of the first vibrating member 110 and the projection of the geometric center of the second vibrating member 210 do not overlap, or the projection of the second vibrating member 210 partially overlaps the projection of the first vibrating member 110, the first vibrating member 110 is connected to a plurality of first connecting members 120 arranged at intervals to avoid the second vibrating member 210.
[0059] It should be noted that the size of the first vibrating member 110 along the vibration direction will affect its vibration sound performance. The size of the first vibrating member 110 along the thickness direction is larger, which is easier to generate strong driving force to improve the amplitude and optimize the low frequency response. The size of the second vibrating member 210 along the vibration direction will also affect the sound performance of the second vibrating member 210. The size of the second vibrating member 210 along the thickness direction is smaller, which is easier to form association with the external member 400 and easier to generate high frequency vibration to improve the high frequency response. The size of the first vibrating member 110 and the second vibrating member 210 along the thickness direction can be set within a suitable range according to actual needs, so as to have better low frequency response and high frequency response respectively.
[0060] With reference to Figure 1 and Figure 3 In some possible embodiments of the present application, the first vibrating member 110 has a first thickness dimension H10 along its vibration direction, and the second vibrating member 210 has a second thickness dimension H20 along its thickness direction. The first thickness dimension H10 and the second thickness dimension H20 can be the same or different. For example, the first thickness dimension H10 is greater than the second thickness dimension H20, so that the first vibrating member 110 can generate stronger driving force to improve the low frequency sound effect and improve the high frequency sound effect of the second vibrating member 210.
[0061] For example, the first thickness dimension 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. The second thickness dimension 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 dimension H10 of the first vibrating member 110 and the second thickness dimension H20 of the second vibrating member 210 are both 1.0 mm.
[0062] With reference to Figure 2 , Figure 5 and Figure 6 In some possible embodiments of the present application, the vibrating member in the form of piezoelectricity (such as the first vibrating member 110 and the second vibrating member 210) can include a substrate and one or more piezoelectric parts arranged on the substrate. In the case of arranging one piezoelectric part on the substrate, the piezoelectric part and the connecting piece can be arranged on the same or different sides of the substrate. In the case of arranging two piezoelectric parts 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.
[0063] For example, the first vibrating member 110 includes a first base plate 111 and a first piezoelectric part 112, and the first piezoelectric part 112 is connected to one side or both sides of the first base plate 111 in the vertical vibration direction; the second vibrating member 210 includes a second base plate 211 and a second piezoelectric part 212, and the second piezoelectric part 212 is connected to the side of the second base plate 211 away from the second connecting member 220, wherein the first piezoelectric part 112 is used for low-frequency response, and the second piezoelectric part 212 is used for high-frequency response.
[0064] In the embodiments of the present application, the connection between the first connecting member 120 and the first vibrating member 110 is that the first connecting member 120 is connected to the first base plate 111. Correspondingly, the connection between the second connecting member 220 and the second vibrating member 210 is that the second connecting member 220 is connected to the second base plate 211.
[0065] On this basis, the size of the base plate 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 sizes of the first base plate 111 and the second base plate 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 sizes of the first piezoelectric part 112 and the second piezoelectric part 212 in the vibration direction can be the same or different.
[0066] It should be noted that the first connecting member 120 is used to provide connection and also provides support for the first vibrating member 110, so as to isolate the first vibrating member 110 from the external member 400, thereby reducing 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 member 120 in the vibration direction.
[0067] In the case where the projection of the first vibrating member 110 and the projection of the second vibrating member 210 have a spacing size, and the first base plate 111 is not provided with the first piezoelectric part 112 on the side close to the first connecting member 120, the third thickness dimension H30 is greater than the maximum amplitude of the first base plate 111 in the vibration direction.
[0068] In the case where the projection of the first vibrating member 110 and the projection of the second vibrating member 210 have a spacing size, and the first base plate 111 is provided with the first piezoelectric part 112 on the side close to the first connecting member 120, the third thickness dimension H30 is greater than the sum of the maximum amplitude of the first base plate 111 in the vibration direction and the size of the first piezoelectric part 112 in the vibration direction.

[0086] In the embodiments of the present application, the piezoelectric part can be stacked by one or more layers of piezoelectric ceramics, 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 to drive the corresponding substrate to deform and vibrate; the less piezoelectric ceramics stacked in the piezoelectric part, the smaller the space occupied, and the better the high-frequency performance obtained. Therefore, the number of layers of piezoelectric ceramics in the piezoelectric part can be set according to actual needs in order to balance the driving force and sound production performance. The number of layers of piezoelectric ceramics of the second piezoelectric part 212 and the number of layers of piezoelectric ceramics of the first piezoelectric part 112 can be the same or different.
