Description

Technical Field

[0001] This manual relates to the field of acoustics, and in particular to vibrating components and loudspeakers. Background Technology

[0002] A loudspeaker produces sound by pushing air to vibrate through a diaphragm. For small MEMS loudspeakers or micro-loudspeakers, because their size is on the order of millimeters, the size of the diaphragm is greatly reduced, resulting in less air being pushed and thus lower low-frequency sensitivity.

[0003] Therefore, it is necessary to propose a vibration component to improve the low-frequency performance of loudspeakers (especially small loudspeakers). Summary of the Invention

[0005] This specification also provides a loudspeaker, comprising: a housing forming a cavity; an acoustic driver located within the cavity; the acoustic driver including a vibration assembly and a drive unit; the vibration assembly including an elastic element and a support element supporting the elastic element, the support element being connected to the housing; the elastic element including a reinforcement region, a first pre-processing region, and a fixing region, the reinforcement region being disposed in the middle of the elastic element, the first pre-processing region being disposed around the periphery of the reinforcement region, and the fixing region being disposed around the periphery of the first pre-processing region; the fixing region being connected to the support element; wherein, when the elastic element vibrates, the first pre-processing region provides the reinforcement region with a first displacement along the vibration direction of the reinforcement region.

[0040] To more clearly illustrate the technical solutions of the embodiments in this specification, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are merely some examples or embodiments of this application. For those skilled in the art, these drawings can be applied to other similar scenarios without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.

[0041] It should be understood that the terms “system,” “device,” “unit,” and / or “module” used herein are one way to distinguish different components, elements, parts, sections, or assemblies at different levels. However, if other terms can achieve the same purpose, they may be replaced by other expressions.

[0042] As indicated in this application and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" do not specifically refer to the singular and may also include the plural. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.

[0043] Flowcharts are used in this application to illustrate the operations performed by the system according to embodiments of this application. It should be understood that the preceding or following operations are not necessarily performed precisely in sequence. Instead, the steps can be processed in reverse order or simultaneously. Furthermore, other operations can be added to these processes, or one or more steps can be removed from them.

[0044] This specification provides a vibration assembly in some embodiments. The vibration assembly can generate vibration in response to mechanical vibration (such as the mechanical vibration of a drive unit). In some embodiments, the vibration assembly can be disposed in a loudspeaker, vibrating under the action of a drive unit, and transmitting the air-conducted sound signal generated by the vibration to the outside of the loudspeaker through a hole in the loudspeaker housing. In some embodiments, the vibration assembly may include an elastic element and a support element, the support element being connected to and supporting the elastic element. In some embodiments, the elastic element may include a reinforcing region, one or more pre-processed regions, and a fixed region, wherein the reinforcing region may be disposed in the middle of the elastic element, one or more pre-processed regions are disposed around the periphery of the reinforcing region, and the fixed region is disposed around the periphery of the one or more pre-processed regions. The support element is connected to the fixed region of the elastic element. In some embodiments, the support element may be located on any surface of the fixed region along the vibration direction of the reinforcing region and connected to the fixed region. In some embodiments, when the elastic element vibrates, one or more pre-processed regions may provide one or more displacements along the vibration direction of the reinforcing region to the reinforcing region. In some embodiments, the vibration displacement or vibration amplitude provided by one or more pre-processed regions to the reinforcing region is the sum of one or more displacements along the vibration direction of the reinforcing region provided by the one or more pre-processed regions. The pre-treated region can be a pre-treated area on the elastic element, which has a stronger deformability than other areas on the elastic element (untreated areas). In some embodiments, the pre-treatment means may include, but are not limited to, bending, changing the material hardness, etc. Since one or more pre-treated regions have a stronger deformability than other areas on the elastic element, providing one or more pre-treated regions can increase the total displacement of the reinforcing region along its vibration direction, that is, it can increase the vibration displacement or vibration amplitude of the reinforcing region. In some embodiments, the elastic element may include a first pre-treated region, which provides a first displacement of the reinforcing region along the vibration direction of the reinforcing region. The first displacement of the reinforcing region in the vibration direction may be the magnitude of the displacement contributed by the first pre-treated region to the vibration of the reinforcing region in its vibration direction. In some embodiments, the elastic element may also include a second pre-treated region, which provides a second displacement of the reinforcing region along the vibration direction of the reinforcing region. The second displacement of the reinforcing region in the vibration direction may be the magnitude of the displacement contributed by the second pre-treated region to the vibration of the reinforcing region in its vibration direction.In some embodiments, one or more pre-processed regions may include one or more folds (e.g., a first fold, a second fold, etc.) that deform when subjected to vibration. The deformation of the folds is greater than that of the untreated elastic element (non-fold) when subjected to vibration, thereby increasing the vibration displacement or vibration amplitude of the enhanced region in its vibration direction when the elastic element vibrates, thereby improving the sensitivity of the vibration component response.

[0045] In some embodiments, when a vibration assembly is applied to a loudspeaker, one or more pre-treated regions (e.g., surrounds) of the elastic element can increase the vibration displacement or amplitude of the reinforcing region in its vibration direction, thereby driving more air vibration and improving the low-frequency performance (e.g., sensitivity) of the loudspeaker. Furthermore, by providing one or more pre-treated regions (e.g., surrounds) on the elastic element to enhance its deformation capability, the elastic element has a greater amount of deformability in the vibration direction of the reinforcing region. This allows the vibration assembly to distribute the stress generated by the vibration impact within one or more pre-treated regions through deformation when the vibration amplitude is large, preventing stress concentration in the elastic element and avoiding damage to the vibration assembly (especially the elastic element) when the vibration amplitude is large, thus improving the reliability of the loudspeaker.

[0046] Figure 1 This is an exemplary frame diagram of a vibration assembly according to some embodiments of this specification. Figure 1 As shown, the vibration assembly 100 may include an elastic element 110 and a support element 120.

[0047] The elastic element can be a component capable of elastic deformation under external load. In some embodiments, the elastic element can be a diaphragm. In some embodiments, the elastic element 110 can be made of a high-temperature resistant material, so that the elastic element 110 maintains its performance during the manufacturing process when the vibration assembly 100 is applied to a vibration sensor or a loudspeaker. In some embodiments, when the elastic element 110 is in an environment of 200°C to 300°C, its Young's modulus and shear modulus do not change or change very little (e.g., the change is within 5%), wherein Young's modulus can be used to characterize the deformation capacity of the elastic element 110 under tension or compression, and shear modulus can be used to characterize the deformation capacity of the elastic element 110 under shear. In some embodiments, the elastic element 110 can be a material with good elasticity (i.e., easy to undergo elastic deformation), so that the vibration assembly 100 has good vibration response capability. In some embodiments, the material of the elastic element 110 can be one or more of organic polymer materials, adhesive materials, etc. In some embodiments, the organic polymer material may be polycarbonate (PC), polyamides (PA), acrylonitrile butadiene styrene (ABS), polystyrene (PS), high impact polystyrene (HIPS), polypropylene (PP), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyurethanes (PU), polyethylene (PE), phenolic resin (PF), urea-formaldehyde resin (UF), melamine-formaldehyde resin (MF), polyarylate (PAR), polyetherimide (PEI), polyimide (PI), or polyethylene naphthalate dicarboxylate. Any one or a combination of glycol ester (PEN), polyetheretherketone (PEEK), silicone, etc.In some embodiments, the organic polymer material may also be various adhesives, including but not limited to gels, silicone, acrylics, polyurethanes, rubbers, epoxy resins, hot melt adhesives, photocurable adhesives, etc., and preferably silicone adhesives or silicone sealants.

[0048] In some embodiments, the Shore hardness of the elastic element 110 can be 1-50 HA. In some embodiments, the Shore hardness of the elastic element 110 can be 1-15 HA. In some embodiments, the Shore hardness of the elastic element 110 can be 14.9-15.1 HA.

[0049] In some embodiments, the projection of the elastic element 110 along the vibration direction of the reinforcing region can be a regular and / or irregular polygon such as a circle, rectangle, pentagon, or hexagon.

[0050] In some embodiments, when the projection of the elastic element 110 along the vibration direction of the reinforcing region is rectangular, the projection dimensions (such as length and width) of the elastic element 110 along the vibration direction of the reinforcing region can be set within a suitable range to ensure the performance of the vibration assembly 100. In some embodiments, the projection of the elastic element 110 along the vibration direction of the reinforcing region is rectangular, and the length of the rectangle can be 4mm-12mm. In some embodiments, the projection of the elastic element 110 along the vibration direction of the reinforcing region is rectangular, and the length of the rectangle can be 5mm-10mm. In some embodiments, the projection of the elastic element 110 along the vibration direction of the reinforcing region is rectangular, and the width of the rectangle can be 4mm-10mm. In some embodiments, the projection of the elastic element 110 along the vibration direction of the reinforcing region is rectangular, and the width of the rectangle can be 5mm-8mm.

[0051] In some embodiments, when the projection of the elastic element 110 along the vibration direction of the reinforcing region is circular, the projection size (e.g., diameter) of the elastic element 110 along the vibration direction of the reinforcing region can be set within a suitable range to ensure the performance of the vibration assembly 100. In some embodiments, the projection of the elastic element 110 along the vibration direction of the reinforcing region is circular, and the diameter of the circle can be 4mm-12mm. In some embodiments, the projection of the elastic element 110 along the vibration direction of the reinforcing region is circular, and the diameter of the circle can be 5mm-10mm.

[0052] In some embodiments, when the projection of the elastic element 110 along the vibration direction of the reinforcing region is a polygon, the projection size of the elastic element 110 along the vibration direction of the reinforcing region (such as the diameter of the circumcircle of the polygon) can be set within a suitable range to ensure the performance of the vibration assembly 100. In some embodiments, the projection of the elastic element 110 along the vibration direction of the reinforcing region is a polygon, and the diameter of the circumcircle of the polygon can be 4mm-12mm. In some embodiments, the projection of the elastic element 110 along the vibration direction of the reinforcing region is a polygon, and the diameter of the circumcircle of the polygon can be 5mm-10mm.

[0053] In some embodiments, for elastic elements 110 with different shapes (i.e., elastic elements 110 having different projected shapes along the vibration direction of the reinforcing region), the thickness of the elastic element 110 along the vibration direction of the reinforcing region can be set within a suitable range to ensure the performance of the vibration assembly 100. In some embodiments, the thickness of the elastic element 110 along the vibration direction of the reinforcing region can be 0.2 mm to 1 mm. In some embodiments, the thickness of the elastic element 110 along the vibration direction of the reinforcing region can be 0.3 mm to 0.7 mm.

[0054] In some embodiments, the elastic element 110 may include a reinforcing region, a first pre-processed region, and a fixing region. The reinforcing region may be located at the center of the elastic element 110. The first pre-processed region is disposed around the periphery of the reinforcing region, providing a first displacement along the vibration direction of the reinforcing region. The fixing region is disposed around the periphery of the first pre-processed region and is connected to the support element 120.

[0055] The first pre-treated area can be a pre-treated area on the elastic element. In some embodiments, pre-treatment can be to change the material hardness. In some embodiments, the first pre-treated area can be a region on the elastic element 110 with a lower hardness than other parts. Because the hardness of the first pre-treated area is lower than that of other parts on the elastic element 110, the first pre-treated area is more prone to deformation when the elastic element 110 vibrates, so that the deformation generated by the first pre-treated area can be greater than the deformation generated by other areas on the elastic element 110 other than the pre-treated area (such as the first pre-treated area), thereby increasing the first displacement provided by the first pre-treated area to the reinforcing area along the vibration direction of the reinforcing area, thereby increasing the vibration amplitude or vibration displacement of the reinforcing area, and further improving the low-frequency sensitivity of the vibration assembly 100. Furthermore, because the first pre-treated area is more prone to deformation, the stress generated in the first pre-treated area is more easily distributed throughout the first pre-treated area during the vibration of the elastic element 110, thereby avoiding stress concentration at certain specific locations (such as the connection between the fixed area and the support element 120) and preventing damage to the elastic element 110.

[0056] In some embodiments, pretreatment may be bending. In some embodiments, the first pretreatment region may include a first folded ring. The folded ring may be a structure with a bent portion protruding from the plane connecting the two ends of the first pretreatment region. The first folded ring deforms when the elastic element 110 vibrates, and the bent portion of the first folded ring tends to straighten during vibration, thereby making the deformation generated by the first folded ring greater than that generated by the non-folded ring region (i.e., other regions on the elastic element 110 besides the folded ring region (such as the first folded ring region)). This increases the first displacement provided by the first pretreatment region to the reinforcement region along the vibration direction of the reinforcement region. In some embodiments, the first displacement is the component of the first folded ring after deformation during vibration that corresponds to the vibration direction of the reinforcement region. Since the first folded ring can generate a larger deformation through the straightening tendency of the bent portion during the vibration of the elastic element 110, the first folded ring can more easily disperse the stress generated in the first pretreatment region, thereby avoiding stress concentration at certain locations and preventing damage to the elastic element 110.

[0057] Since the pre-processed area is more prone to deformation than other areas of the elastic element 110, by setting the first pre-processed area, the total stiffness of the elastic element 110 can be reduced and the compliance of the vibration assembly 100 can be improved. When the mass of the elastic element 110 remains unchanged, the resonance peak f0 of the vibration assembly 100 can be shifted forward (i.e., moved to a lower frequency), thereby improving the low-frequency sensitivity of the vibration assembly 100.

[0058] In some embodiments, the cross-sectional shape of the first folded ring on a section parallel to the vibration direction of the reinforcing region may include, but is not limited to, one or more of the following: circular arc, elliptical arc, zigzag, pointed tooth, and square tooth.

[0059] In some embodiments, the first folded ring may have a first bending direction. The first bending direction may be a direction perpendicular to the line segment connecting the two ends of the first folded ring and towards the bent portion protruding from the plane on any projection plane parallel to the vibration direction of the reinforcing region. In some embodiments, when the cross-sectional shape of the first folded ring on the projection plane parallel to the vibration direction of the reinforcing region is arc-shaped, the first bending direction may be a direction perpendicular to the arc protrusion (i.e., the bent portion) towards the line connecting the two ends of the arc. In some embodiments, the first bending direction may be parallel to the vibration direction of the reinforcing region. In some embodiments, the first bending direction may be perpendicular to the vibration direction of the reinforcing region. In some embodiments, the first bending direction may form a first angle with the vibration direction of the reinforcing region. More information about the first pre-processing region can be found in this specification. Figures 2-6 , and its related descriptions.

[0060] In some embodiments, the elastic element 110 may further include a second pre-processed region, which is disposed around the periphery of the first pre-processed region. In some embodiments, the second pre-processed region and the first pre-processed region may be directly connected, i.e., the distance between the second pre-processed region and the first pre-processed region is zero. In some embodiments, the second pre-processed region and the first pre-processed region may also be spaced apart, i.e., there is a preset distance (e.g., 10 micrometers, 100 micrometers, etc.) between the second pre-processed region and the first pre-processed region. In some embodiments, the second pre-processed region may provide a second displacement along the vibration direction of the reinforcing region to the reinforcing region. The second displacement may be the magnitude of the displacement contributed by the second pre-processed region to the vibration of the reinforcing region in its vibration direction.

[0061] In some embodiments, the second pre-processed region may be another pre-processed region on the elastic element other than the first pre-processed region. Therefore, when the elastic element 110 vibrates, the deformation generated by the second pre-processed region may be greater than the deformation generated by other regions on the elastic element 110 other than the pre-processed regions (e.g., the first and second pre-processed regions). In some embodiments, the second pre-processed region may have a structure similar to the first pre-processed region.

[0062] In some embodiments, the second pretreatment region may include a second folded ring. The second folded ring deforms when the elastic element 110 vibrates, and the bent portion of the second folded ring tends to straighten during vibration, thereby increasing the deformation of the second folded ring compared to the non-folded ring region. This enhances the second displacement provided by the second pretreatment region to the reinforcement region along the vibration direction of the reinforcement region. The component of the deformed dimension of the second folded ring in the vibration direction of the reinforcement region is the second displacement. In some embodiments, the cross-sectional shape of the second folded ring on a section parallel to the vibration direction of the reinforcement region may include, but is not limited to, one or more of the following: circular arc, elliptical arc, polygonal line, pointed tooth, and square tooth.

[0063] In some embodiments, the second folded ring may have a second bending direction. The second bending direction may be a direction perpendicular to the line segment connecting the two ends of the second folded ring and towards the bent portion protruding from the plane on any projection plane parallel to the vibration direction of the reinforcing region. In some embodiments, the second bending direction may be the same as or different from the first bending direction (e.g., opposite, perpendicular, etc.). The second bending direction being opposite to the first bending direction means that the protruding direction of the bent portion of the first folded ring and the protruding direction of the bent portion of the second folded ring are opposite in the same plane. In some embodiments, when the first and second folded rings are smooth curves (curvature not equal to 0, and the first derivative of the curve is continuous), the center of curvature corresponding to any point on the first folded ring and the center of curvature corresponding to any point on the second folded ring are located on opposite sides of the elastic element, then the second bending direction is opposite to the first bending direction. In some embodiments, more information regarding the second pre-processing region can be found in this specification. Figures 7-18 , and its related descriptions.

[0064] In some embodiments, the elastic element 110 may further include a non-pre-treated region. In some embodiments, when the first pre-treated region and the second pre-treated region are spaced apart, the region connecting the first pre-treated region and the second pre-treated region may be a non-pre-treated region. In some embodiments, when the first pre-treated region and the reinforcing region are spaced apart, the region connecting the first pre-treated region and the reinforcing region may be a non-pre-treated region. In some embodiments, when the elastic element 110 vibrates, the non-pre-treated region can also deform to provide displacement for the vibration displacement or vibration amplitude of the reinforcing region. In some embodiments, the deformation of the non-pre-treated region depends on the parameters of the material of the elastic element 110 itself (such as Young's modulus), and the displacement it provides when the elastic element 110 vibrates is much smaller than the first displacement or the second displacement. In some embodiments, when the reinforcing region, the first pre-treated region, and the second pre-treated region are all directly connected (not spaced apart), the elastic element 110 may also not include a non-pre-treated region.

[0065] In some embodiments, the vibration assembly 100 may include a support element 120. The support element 120 may be connected to a fixed region of the elastic element 110. In some embodiments, the support element 120 may include a clamping portion and a deforming portion. The clamping portion and the deforming portion may be disposed opposite to each other and located on two surfaces of the fixed region of the elastic element 110 along the vibration direction of the reinforcing region, such that the fixed region is clamped between the clamping portion and the deforming portion of the support element 120. In some embodiments, the support element 120 may also not include a clamping portion, in which case the deforming portion may be disposed on either surface of the fixed region of the elastic element 110 along the vibration direction of the reinforcing region and connected to the fixed region (e.g., bonded). In some embodiments, the support element 120 (e.g., the deforming portion) is stretchable along the vibration direction of the reinforcing region, thereby providing a third displacement amount along the vibration direction of the reinforcing region to the reinforcing region through stretching deformation when the elastic element 110 vibrates. The third displacement amount may be the magnitude of the displacement contributed by the support element 120 to the reinforcing region during vibration in its vibration direction.

[0066] In some embodiments, the material of the support element 120 may be one or more of rigid materials, semiconductor materials, organic polymer materials, and adhesive materials. In some embodiments, rigid materials may include, but are not limited to, metal materials and alloy materials. Semiconductor materials may include, but are not limited to, one or more of silicon, silicon dioxide, silicon nitride, and silicon carbide. Organic polymer materials may include, but are not limited to, one or more of polyimide (PI), parylene, polydimethylsiloxane (PDMS), and hydrogels. Adhesive materials may include, but are not limited to, one or more of gels, silicone, acrylics, polyurethanes, rubbers, epoxy resins, hot-melt adhesives, and photocurable adhesives. In some embodiments, to enhance the connection force between the support element 120 and the elastic element 110 and improve the reliability between them, the material of the support element 120 may be silicone adhesive or silicone sealant. In some embodiments, the cross-sectional shape of the support element 120 in a section parallel to the vibration direction of the reinforcement region may be a regular and / or irregular geometric shape such as a rectangle, circle, ellipse, or pentagon. Meanwhile, by setting up a flexible support element 120, the elastic element 110 is prevented from directly contacting the shell, reducing stress concentration at the connection end between the elastic element 110 and the shell (the shell is generally a rigid body), thereby further protecting the elastic element 110.

[0067] In some embodiments, the height of the support element 120 along the vibration direction of the reinforcing region can be reasonably set according to the requirements of the vibration component 100 (such as the overall size of the vibration component 100, the vibration displacement or vibration amplitude of the reinforcing region in its vibration direction). In some embodiments, the height of the deformable portion of the support element 120 along the vibration direction of the reinforcing region can be 50µm-1000µm. In some embodiments, the height of the deformable portion of the support element 120 along the vibration direction of the reinforcing region can be 100µm-800µm.

[0068] In some embodiments, the cross-sectional area of ​​the support element 120 perpendicular to the vibration direction of the reinforcing region may have different cross-sectional areas along the vibration direction of the reinforcing region. For example, a curved structure may be provided on the side of the support element 120 perpendicular to the vibration direction of the reinforcing region and close to the reinforcing region (also referred to as the inner side of the support element 120), such that the cross-sectional area of ​​the inner side of the support element 120 is greater than the cross-sectional area of ​​the outer side of the support element 120 (the side of the support element 120 perpendicular to the vibration direction of the reinforcing region and far from the reinforcing region).

[0069] In some embodiments, the support element 120 may deform in response to a vibration signal from the elastic element 110, providing a third displacement along the vibration direction of the reinforcement region, thereby increasing the total displacement generated by the reinforcement region in its vibration direction and further improving the low-frequency sensitivity of the vibration assembly 100. More information about the support element 120 can be found in this specification. Figures 19-28 , and its related descriptions.

[0070] Figures 2-6 This is an exemplary structural diagram of a vibration assembly shown according to some embodiments of this specification.

[0071] like Figure 2 As shown, the vibration assembly 200 may include an elastic element 210 and a support element 220. In some embodiments, the elastic element 210 may include a reinforcing region 211, a first pre-treatment region 212, and a fixing region 213. The reinforcing region 211 may be located in the center of the elastic element 210, the first pre-treatment region 212 is disposed around the periphery of the reinforcing region 211, and the fixing region 213 is disposed around the periphery of the first pre-treatment region 212. The support element 220 is connected to the elastic element 210 through the fixing region 213.

[0072] In some embodiments, during the vibration of the elastic element 210, the first pre-processed region 212 may undergo a certain degree of deformation along the vibration direction of the reinforcing region 211, thereby providing the reinforcing region 211 with a first displacement along the vibration direction of the reinforcing region 211, and thus increasing the displacement generated by the reinforcing region 211 in its vibration direction.

[0073] In some embodiments, the projections of the elastic element 210 and the reinforcing region 211 along the vibration direction of the reinforcing region 211 can be regular and / or irregular polygons such as circles, rectangles, rectangles with rounded corners, pentagons, and hexagons. The projections of the first pre-processing region 212 and the fixing region 213 of the elastic element 210 along the vibration direction of the reinforcing region 211 can be regular and / or irregular polygonal rings such as circular rings, rectangular rings, pentagonal rings, and hexagonal rings, corresponding to regular and / or irregular polygons such as circles, rectangles, pentagons, and hexagons.

[0074] In some embodiments, the reinforcing regions 211 can have different dimensions for different shapes. In some embodiments, when the projection of the reinforcing region 211 along the vibration direction is rectangular, the length of the rectangle can be 2.5mm-8mm. In some embodiments, the projection of the reinforcing region 211 along the vibration direction is rectangular, and the length of the rectangle can be 3mm-6mm. In some embodiments, when the projection of the reinforcing region 211 along the vibration direction is rectangular, the width of the projected rectangle can be 1mm-6mm. In some embodiments, the projection of the reinforcing region 211 along the vibration direction is rectangular, and the width of the rectangle can be 2mm-5mm.

[0075] In some embodiments, when the projection of the reinforcing region 211 along the vibration direction of the reinforcing region 211 is circular, the diameter of the circle can be 2mm-10mm. In some embodiments, the projection of the reinforcing region 211 along the vibration direction of the reinforcing region 211 is circular, and the diameter of the circle can be 3mm-8mm.

[0076] In some embodiments, when the projection of the reinforcing region 211 along the vibration direction of the reinforcing region 211 is a polygon, the diameter of the circumcircle of the polygon can be 2mm-10mm. In some embodiments, the projection of the reinforcing region 211 along the vibration direction of the reinforcing region 211 is a polygon, and the diameter of the circumcircle of the polygon can be 3mm-8mm.

[0077] In some embodiments, for reinforcement regions 211 with different shapes (i.e., reinforcement regions 211 have different projected shapes along the vibration direction of reinforcement regions 211), the thickness of the reinforcement regions 211 along the vibration direction can be set within a suitable range to ensure the performance of the vibration assembly 200. In some embodiments, the thickness of the reinforcement regions 211 along the vibration direction can be 20µm-200µm. In some embodiments, the thickness of the reinforcement regions 211 along the vibration direction can be 40µm-150µm.

[0078] In some embodiments, the material of the reinforcing region 211 may be one or more of metal films, non-metals, etc. In some embodiments, the metal film may include, but is not limited to, aluminum alloys, magnesium-aluminum alloys, titanium alloys, magnesium-lithium alloys, copper, beryllium, 85 steel, etc., or any combination thereof. In some embodiments, the non-metal may include, but is not limited to, man-made and / or natural silk products (such as silk, sericulture, etc.), man-made fibers, silk films, fabric films, nylon films, pure carbon fibers, composite carbon fibers, etc., or any combination thereof.

[0079] In some embodiments, the first preprocessing region 212 may include a first fold 2121, which may have a first bending direction. See also Figures 2-4 The first bending direction can be on the projection plane parallel to the vibration direction of the reinforcement region 211, perpendicular to the line segment S connecting the two ends of the first fold ring 2121, and towards the bending portion protruding from the plane.

[0080] In some embodiments, see Figure 2 One end of the first folded ring 2121 can be connected to the reinforcing region 211, and the other end of the first folded ring 2121 protrudes beyond the surface of the reinforcing region 211 perpendicular to the vibration direction. In some embodiments, the first bending direction can form a first angle with the vibration direction of the reinforcing region 211. When the first bending direction forms a first angle with the vibration direction of the reinforcing region 211, the first folded ring 2121 can deform in the first bending direction (or perpendicular to the first bending direction). The deformation generated in the first bending direction (or perpendicular to the first bending direction) has a certain deformation component in the vibration direction of the reinforcing region 211. This deformation component can enable the first pre-processing region 212 to provide the reinforcing region 211 with a first displacement along the vibration direction of the reinforcing region 211.

[0081] In some embodiments, the first fold 2121 may be an arc-shaped fold (such as a circular arc, an elliptical arc, etc.). In some embodiments, the first fold 2121 may also be a curved fold (such as a parabola, etc.). In some embodiments, the first fold 2121 may also be a broken-line fold (such as a toothed broken line, a square-toothed broken line, etc.).

[0082] By designing the first fold 2121, the elastic element 210 can have a larger deformability along the vibration direction of the reinforcing region 211, thereby increasing the first displacement provided by the first pre-treatment region 212 to the reinforcing region 211 along the vibration direction of the reinforcing region 211, and further increasing the vibration amplitude or vibration displacement of the reinforcing region 211 in its vibration direction, thus improving the low-frequency sensitivity of the vibration assembly 200. In some embodiments, by designing the first fold 2121, the entire bent portion of the first fold 2121 can also obtain a more uniform deformation when the elastic element 210 vibrates, greatly reducing stress concentration problems, thereby improving the reliability of the vibration assembly 200.

[0083] In some embodiments, the angle between the first bending direction and the vibration direction of the reinforcing region 211 can be between 0° and 360°. In some embodiments, the angle between the first bending direction and the vibration direction of the reinforcing region 211 can be between 0° and 180°. In some embodiments, the angle between the first bending direction and the vibration direction of the reinforcing region 211 can be between 60° and 120°.

[0084] In some embodiments, see Figure 3 The first folding ring 2121 may be disposed around the periphery of the reinforcing region 211 along a vibration direction perpendicular to the reinforcing region 211. In some embodiments, the first bending direction may be parallel to the vibration direction of the reinforcing region 211. When the first bending direction is parallel to the vibration direction of the reinforcing region 211, the first folding ring 2121 may deform in the first bending direction, that is, the first folding ring 2121 may deform in the vibration direction of the reinforcing region 211, thereby providing the first pre-processing region 212 with a first displacement along the vibration direction of the reinforcing region 211. When the first bending direction is parallel to the vibration direction of the reinforcing region 211, the first displacement may be the component of the deformed length of the first pre-processing region 212 (the length connecting its two ends on a projection plane parallel to the vibration direction of the reinforcing region 211) in the vibration direction. According to the Pythagorean theorem, this component is greater than the change in length of the first pre-processed region 212 after deformation (i.e., the deformation). That is, by setting the first bending direction parallel to the vibration direction of the reinforcing region 211, the first displacement provided by the first pre-processed region 212 can be greater than its own deformation, thereby increasing the vibration displacement or vibration amplitude of the reinforcing region 211.

[0085] To ensure the required resonant frequency of the vibration assembly 200, with a fixed overall size of the vibration assembly 200, the larger the projected size of the reinforcement region 211 along its vibration direction, the better. With a fixed overall size of the vibration assembly 200, a larger projected size of the reinforcement region 211 along its vibration direction reduces the available space for the first folded ring 2121 around the reinforcement region 211. Furthermore, a smaller size of the first folded ring 2121 leads to an increase in the stiffness of the elastic element 210, and thus an increase in the device's resonant frequency. In some embodiments, see... Figure 4 The first folding ring 2121 can be disposed on the side of the reinforcing region 211 parallel to its vibration direction. In some embodiments, the first bending direction can be perpendicular to the vibration direction of the reinforcing region 211. In some embodiments, the first bending direction can be perpendicular to the vibration direction of the reinforcing region 211 and away from the direction in which the reinforcing region 211 is located. When the first bending direction is perpendicular to the vibration direction of the reinforcing region 211, the first folding ring 2121 can deform in the direction perpendicular to the first bending direction, that is, the first folding ring 2121 can deform in the vibration direction of the reinforcing region 211, thereby increasing the first displacement amount provided by the first pre-processing region 212 to the reinforcing region 211 along the vibration direction of the reinforcing region 211. When the first bending direction is perpendicular to the vibration direction of the reinforcing region 211, the first displacement amount can be the change in length of the first pre-processing region 212 after deformation (i.e., the deformation amount).

[0086] Compared to other non-perpendicular configurations, by setting the first bending direction to be perpendicular to the vibration direction of the reinforcing region 211, the first fold ring 2121 can have a larger design size, thereby significantly improving the deformation capacity of the first fold ring 2121 along the vibration direction of the reinforcing region 211 (i.e., having a larger deformation amount). This can greatly reduce the stiffness of the elastic element 210 along the vibration direction of the reinforcing region 211, while also reducing the projected size of the first fold ring 2121 along the vibration direction of the reinforcing region 211.

[0087] In some embodiments, to increase the deformation of the first folding ring 2121 during vibration of the reinforced region 211, see [reference needed]. Figures 2-4The height and length of the first folded ring 2121 along the first bending direction can be reasonably set to meet the displacement requirements of the reinforcement region 211 along its vibration direction. In some embodiments, the height of the first folded ring 2121 along the first bending direction can be represented by the maximum value of the distance between the bent portion of the first folded ring 2121 and the line segment S in the first bending direction on a projection plane parallel to the vibration direction of the reinforcement region 211. The length of the first folded ring 2121 along the perpendicular direction can be represented by the distance between the two ends of the first folded ring 2121 on a projection plane parallel to the vibration direction of the reinforcement region 211 (i.e., the length of the line segment S).

[0088] In some embodiments, the height dimension of the projected shape of the first folded ring 2121 on a projection plane parallel to the vibration direction of the reinforcing region 211 can be 50µm-250µm. In some embodiments, the height dimension of the projected shape of the first folded ring 2121 on a projection plane parallel to the vibration direction of the reinforcing region 211 can be 80µm-200µm. In some embodiments, the dimension of the projected shape of the first folded ring 2121 along the radial direction of its projected shape or the radial direction of the circumcircle of its projected shape on a projection plane parallel to the vibration direction of the reinforcing region 211 is defined as the length dimension of the first folded ring 2121. In some embodiments, the length dimension of the projected shape of the first folded ring 2121 on a projection plane parallel to the vibration direction of the reinforcing region 211 can be 400µm-800µm. In some embodiments, the length dimension of the projected shape of the first folded ring 2121 on a projection plane parallel to the vibration direction of the reinforcing region 211 can be 500µm-700µm. In some embodiments, the ratio of the height to the length of the projected shape of the first folded ring 2121 on a projection plane parallel to the vibration direction of the reinforcing region 211 can be between 1:16 and 5:8. In some embodiments, the ratio of the height to the length of the projected shape of the first folded ring 2121 on a projection plane parallel to the vibration direction of the reinforcing region 211 can be between 1:8 and 1:2. In some embodiments, the ratio of the height to the length of the projected shape of the first folded ring 2121 on a projection plane parallel to the vibration direction of the reinforcing region 211 can be between 1:4 and 3:4.

[0089] In some embodiments, the first displacement provided by the first pretreatment region 212 (first fold 2121) to the reinforcement region 211 along the vibration direction of the reinforcement region 211 can be 1µm-50µm. In some embodiments, the first displacement provided by the first pretreatment region 212 (first fold 2121) to the reinforcement region 211 along the vibration direction of the reinforcement region 211 can be 4µm-30µm.

[0090] In some embodiments, see Figures 2-6 The cross-sectional shape of the first folded ring 2121 on a section parallel to the vibration direction of the reinforcing region 211 can be, but is not limited to, one or more of the following: circular arc, elliptical arc, zigzag, pointed tooth, and square tooth. For example, as... Figures 2-4 As shown, the first folded ring 2121 has an arc-shaped cross-section on a section parallel to the vibration direction of the reinforcing region 211. For example, as... Figure 5 As shown, the first folded ring 2121 has a square toothed cross-sectional shape on a section parallel to the vibration direction of the reinforcing region 211. For example, as... Figure 6 As shown, the first folded ring 2121 has a toothed cross-sectional shape on the section parallel to the vibration direction of the reinforcement region 211.

[0091] In some embodiments, first folded rings 2121 with different cross-sectional shapes can have different deformation capabilities in the vibration direction of the reinforcing region 211, such that the first pre-processing region 212 provides different first displacements along the vibration direction of the reinforcing region 211. In some embodiments, the cross-sectional shape of the first folded ring 2121 can be set accordingly based on the requirement that the first pre-processing region 212 provides the first displacement along the vibration direction of the reinforcing region 211; however, this specification does not impose any particular limitation on this aspect.

[0092] In some embodiments, see Figures 2-6 The support element 220 can be located on any surface of the fixed region 213 along the vibration direction of the reinforcing region 211 and connected to the fixed region 213 (e.g., bonded). In some embodiments, when the vibration assembly 200 is disposed in the loudspeaker, the support element 220 can be connected to other structures of the loudspeaker (e.g., housing) to support the elastic element 210.

[0093] In some embodiments, the material of the support element 220 may be one or more of semiconductor materials, organic polymer materials, and adhesive materials. Semiconductor materials may include, but are not limited to, one or more of silicon, silicon dioxide, silicon nitride, and silicon carbide. Organic polymer materials may include, but are not limited to, one or more of polyimide (PI), pyrene, polydimethylsiloxane (PDMS), hydrogels, and plastics. Adhesive materials may include, but are not limited to, one or more of gels, silicone, acrylics, polyurethanes, rubbers, epoxy resins, hot-melt adhesives, and photocurable adhesives. In some embodiments, to enhance the connection between the support element 220 and the elastic element 210 (fixed region 213) and improve the reliability between the support element 220 and the elastic element 210, the material of the support element 220 may be silicone adhesive, silicone sealant, etc. In some embodiments, the material of the support element 220 may also be a rigid material. In some embodiments, rigid materials may include, but are not limited to, metal materials and alloy materials.

[0094] In some embodiments, the support element 220 may also deform to a certain extent along the vibration direction of the reinforcement region 221, thereby providing the reinforcement region 221 with a displacement along the vibration direction of the reinforcement region 221. In some embodiments, the support element 220 may include a deformable portion, which may have a certain deformation capability along the vibration direction of the reinforcement region 211, thereby providing the reinforcement region 221 with a displacement along the vibration direction of the reinforcement region 221, further increasing the vibration amplitude or vibration displacement of the reinforcement region 211 along its vibration direction, and improving the low-frequency sensitivity of the vibration assembly 200. For details regarding the support element 220, please refer to [link to relevant documentation]. Figures 19-28 , and its related descriptions.

[0095] Figures 7-18 This is an exemplary structural diagram of a vibration assembly shown according to some embodiments of this specification.

[0096] In some embodiments, one or more elements of the vibration assembly 700 (e.g., reinforcement region 711, first pretreatment region 712, fixing region 714, support element 720, etc.) and Figures 2-6One or more elements of the vibration assembly 200 shown (e.g., reinforcement region 211, first pre-treatment region 212, fixing region 213, support element 220, etc.) may be the same or similar; that is, the vibration assembly 700 may include a reinforcement region 711, a first pre-treatment region 712, a fixing region 714, and a support element 720. The difference from the vibration assembly 200 is that the elastic element 710 of the vibration assembly 700 may further include a second pre-treatment region 713. The second pre-treatment region 713 may provide a second displacement of the reinforcement region 711 along the vibration direction of the reinforcement region 711. The second displacement may be the magnitude of the displacement contributed by the second pre-treatment region 713 to the vibration of the reinforcement region 711 in its vibration direction.

[0097] In some embodiments, by providing a second pre-processing region 713 for the elastic element 710, a second displacement along the vibration direction of the reinforcing region 711 can be provided to the reinforcing region 711, thereby further increasing the vibration displacement or vibration amplitude (including the first and second displacements) of the reinforcing region 711 in its vibration direction. The increased vibration displacement or vibration amplitude of the reinforcing region 711 in its vibration direction allows the elastic element 710 to drive more air vibrations during vibration, thereby improving the low-frequency sensitivity of the vibration assembly 700. In some embodiments, when the vibration amplitude of the vibration assembly 700 is large, the first pre-processing region 712 and the second pre-processing region 713 can store the vibration impact energy in the form of deformation energy within the first pre-processing region 712 and the second pre-processing region 713 respectively through deformation. The first pre-processing region 712 and the second pre-processing region 713 perform multiple damping attenuation movements, thereby dissipating the large vibration impact energy through damping movements, preventing damage to the vibration assembly 700 (especially the elastic element 710) during vibration, and improving the reliability of the vibration assembly 700.

[0098] In some embodiments, the first displacement amount provided by the first preprocessing region 712 to the reinforcing region 711 along the vibration direction of the reinforcing region 711 and the second displacement amount provided by the second preprocessing region 713 to the reinforcing region 711 along the vibration direction of the reinforcing region 711 may be the same or different. In some embodiments, the ratio of the first displacement amount to the second displacement amount may be 1:50-50:1. In some embodiments, the ratio of the first displacement amount to the second displacement amount may be 1:10-10:1. In some embodiments, the ratio of the first displacement amount to the second displacement amount may be 1:2-5:1. In some embodiments, the second displacement amount (or first displacement amount) provided by the second preprocessing region 713 (or the first preprocessing region 712) to the reinforcing region 711 along the vibration direction of the reinforcing region 711 may be 1µm-50µm. In some embodiments, the second displacement amount (or first displacement amount) provided by the second preprocessing region 713 (or the first preprocessing region 712) to the reinforcing region 711 along the vibration direction of the reinforcing region 711 may be 4µm-30µm.

[0099] In some embodiments, the second preprocessing region 713 may be disposed around the periphery of the first preprocessing region 712, and the fixing region 714 may be disposed around the periphery of the second preprocessing region 713. In some embodiments, the inner peripheral side (closer to the periphery of the reinforcing region 711) of the second preprocessing region 713 is connected to the periphery of the first preprocessing region 712, and the outer peripheral side (away from the periphery of the reinforcing region 711) of the second preprocessing region 713 is connected to the periphery of the fixing region 714. In some embodiments, the projections of the reinforcing region 711, the first preprocessing region 712, the second preprocessing region 713, and the fixing region 714 of the elastic element 710 along the vibration direction of the reinforcing region 711 are arranged sequentially from the inside to the outside. In some embodiments, the projections of the elastic element 710 and the reinforcing region 711 along the vibration direction of the reinforcing region 711 may be regular and / or irregular polygons such as circles, rectangles, pentagons, and hexagons. The projection of the second preprocessing region 713 along the vibration direction of the enhancement region 711 can be a regular and / or irregular polygonal ring, such as a circular ring, rectangular ring, pentagonal ring, or hexagonal ring, corresponding to regular and / or irregular polygons such as circles, rectangles, pentagons, and hexagons.

[0100] In some embodiments, see Figure 7-9 The second preprocessing region 713 can be directly connected to the first preprocessing region 712, that is, the distance between the second preprocessing region 713 and the first preprocessing region 712 is zero. The direct connection between the second preprocessing region 713 and the first preprocessing region 712 can also be understood as the periphery of the second preprocessing region 713 (closer to the periphery of the first preprocessing region 712) being directly connected to the periphery of the first preprocessing region 712 (closer to the periphery of the second preprocessing region 713).

[0101] In some embodiments, see Figure 10-11 The second preprocessing region 713 and the first preprocessing region 712 can also be spaced apart, that is, there is a specific distance d between the second preprocessing region 713 and the first preprocessing region 712. The specific distance d can be the distance between the periphery of the second preprocessing region 713 (near the periphery of the first preprocessing region 712) and the periphery of the first preprocessing region 712 (near the periphery of the second preprocessing region 713). In some embodiments, the periphery of the second preprocessing region 713 and the periphery of the first preprocessing region 712 can be connected by a non-preprocessing region. In some embodiments, the width of the projection of the non-preprocessing region onto a plane perpendicular to the vibration direction of the reinforcing region 711 is d.

[0102] In some embodiments, a direct connection or a spaced arrangement between the second pretreatment region 713 and the first pretreatment region 712 can adjust the deformation capabilities of the second pretreatment region 713 and the first pretreatment region 712, thereby adjusting the second displacement provided by the second pretreatment region 713 to the reinforcement region 711 along the vibration direction of the reinforcement region 711, and the first displacement provided by the first pretreatment region 712 to the reinforcement region 711 along the vibration direction of the reinforcement region 711. Alternatively, a direct connection or a spaced arrangement between the second pretreatment region 713 and the first pretreatment region 712 can also adjust the stiffness of the elastic element 710. In some embodiments, the stiffness of the elastic element 710 when the second pretreatment region 713 and the first pretreatment region 712 are directly connected can be less than the stiffness of the elastic element 710 when the second pretreatment region 713 and the first pretreatment region 712 are spaced apart. In some embodiments, by setting the connection method between the second pretreatment region 713 and the first pretreatment region 712, the resonant frequency and sensitivity of the vibration assembly 700 can be adjusted.

[0103] In some embodiments, the specific distance d between the second preprocessing region 713 and the first preprocessing region 712 can range from 0µm to 500µm. In some embodiments, the specific distance d between the second preprocessing region 713 and the first preprocessing region 712 can range from 0µm to 300µm. In some embodiments, the specific distance d between the second preprocessing region 713 and the first preprocessing region 712 can range from 0µm to 100µm.

[0104] In some embodiments, see Figures 12-15 The second preprocessing region 713 may include a second fold 7131. The second fold 7131 may have a second bending direction. The second bending direction may be perpendicular to the plane connecting the two ends of the second fold 7131 and toward the bent portion protruding from the plane.

[0105] In some embodiments, the cross-sectional shape of the second fold 7131 in a section parallel to the vibration direction of the reinforcing region 711 may include, but is not limited to, an arc shape (e.g., Figure 8 ), elliptical arc, zigzag, serrated (e.g., Figure 9 ), square-toothed (e.g., Figure 10 One or more of the following. In some embodiments, second folding rings 7131 with different cross-sectional shapes may have different deformation capabilities in the vibration direction of the reinforcing region 711, such that the second pre-processing region 713 provides different amounts of second displacement along the vibration direction of the reinforcing region 711 to the reinforcing region 711. In some embodiments, the cross-sectional shape of the second folding ring 7131 may be set accordingly according to the requirement that the second pre-processing region 713 provides the second displacement along the vibration direction of the reinforcing region 711 to the reinforcing region 711; however, this specification does not impose any particular limitation on this embodiment.

[0106] In some embodiments, see Figure 12 The first bending direction of the first fold ring 7121 and the second bending direction of the second fold ring 7131 may be the same. See also the following embodiments: Figures 13-15 The first bending direction of the first fold 7121 and the second bending direction of the second fold 7131 may be different. In some embodiments, the first fold and the second fold are smooth curves (curvature not equal to 0, and the first derivative of the curve is continuous). When the first bending direction of the first fold 7121 and the second bending direction of the second fold 7131 are the same, the center of curvature corresponding to a point on the first fold 7121 and the center of curvature corresponding to a point on the second fold 7131 may be located on the same side of the elastic element in the vibration direction of the reinforcement region 711. In some embodiments, the first fold and the second fold are smooth curves (curvature not equal to 0, and the first derivative of the curve is continuous). When the first bending direction of the first fold 7121 and the second bending direction of the second fold 7131 are not the same, the center of curvature corresponding to a point on the first fold 7121 and the center of curvature corresponding to a point on the second fold 7131 may be located on opposite sides of the elastic element in the vibration direction of the reinforcement region 711.

[0107] In some embodiments, see Figure 13 The first bending direction of the first folding ring 7121 and the second bending direction of the second folding ring 7131 can be opposite. This can be achieved by the protruding directions of the bent portions of the first folding ring 7121 and the second folding ring 7131 being in opposite directions within the same plane. In this configuration, the vibration displacement or amplitude of the reinforcing region 711 along its vibration direction is formed by the superposition of the first displacement H1 and the second displacement H2.

[0108] In some embodiments, see Figures 14A-14C The first bending direction of the first fold ring 7121 and the second bending direction of the second fold ring 7131 may be perpendicular. See also the following embodiments: Figure 14A The first bending direction of the first folding ring 7121 is parallel to the vibration direction of the reinforcing region 711. One end of the second folding ring 7131 is connected to the first folding ring, and the other end of the second folding ring 7131 is away from the plane where the reinforcing region 711 is located along the first bending direction. In some embodiments, the second bending direction is perpendicular to the vibration direction of the reinforcing region 711. See also: [link to embodiments]. Figure 14A The second bending direction of the second fold 7131 is away from the center of the elastic element 710. In some embodiments, the second bending direction is towards the center of the elastic element 710. In this configuration, the vibration displacement or vibration amplitude of the reinforcing region 711 along the vibration direction of the reinforcing region 711 is formed by the superposition of the first displacement H1 and the second displacement H2. In some embodiments, see Figure 14B and Figure 14C The first bending direction of the first folding ring 7121 is parallel to the vibration direction of the reinforcing region 711. One end of the second folding ring 7131 is connected to the first folding ring 7121, and the other end of the second folding ring 7131 is located away from the plane of the reinforcing region 711 in a direction opposite to the first bending direction. In some embodiments, the second bending direction is perpendicular to the vibration direction of the reinforcing region 711. See also... Figure 14B The second bending direction of the second fold ring 7131 faces the center of the elastic element 710. See also, in some embodiments... Figure 14C The second bending direction of the second fold ring 7131 is away from the middle of the elastic element 710. In this configuration, the vibration displacement or vibration amplitude of the reinforcing region 711 along the vibration direction of the reinforcing region 711 is formed by the superposition of the first displacement H1 and the second displacement H2.

[0109] By setting the first bending direction of the first folding ring 7121 and the second bending direction of the second folding ring 7131 to be perpendicular to each other, the second folding ring 7131 can have a larger design size, thereby making the second folding ring 7131 have a larger deformation in the vibration direction of the reinforcement region 711. This increases the second displacement provided by the second pre-processing region 1122 to the reinforcement region 711 along the vibration direction of the reinforcement region 711, further increasing the vibration displacement or vibration amplitude of the reinforcement region 711 along its vibration direction, and improving the low-frequency sensitivity of the vibration component 700.

[0110] In some embodiments, such as Figure 15As shown, the first bending direction of the first folding ring 7121 and the second bending direction of the second folding ring 7131 can form a second angle. In this configuration, the vibration displacement or amplitude of the reinforcing region 711 along its vibration direction is formed by the superposition of the first displacement H1 and the second displacement H2. In some embodiments, by setting the first bending direction of the first folding ring 7121 and the second bending direction of the second folding ring 7131, the magnitudes of the first displacement H1 and the second displacement H2 can be adjusted, thereby adjusting the vibration displacement or amplitude of the reinforcing region 711 along its vibration direction.

[0111] In some embodiments, the angle between the first bending direction and the second bending direction can be between 0° and 360°. In some embodiments, the angle between the first bending direction and the second bending direction can be between 60° and 120°.

[0112] In some embodiments, the first bending direction of the first fold 7121 and the second bending direction of the second fold 7131 may be parallel. For example, as... Figures 12-13 As shown, the first bending direction of the first fold 7121 is parallel to the second bending direction of the second fold 7131. When the first bending direction of the first fold 7121 is parallel to the second bending direction of the second fold 7131, the first bending direction of the first fold 7121 and the second bending direction of the second fold 7131 can be the same (for example, Figure 12 (as shown) or the opposite (e.g., Figure 13 (As shown).

[0113] It should be noted that the settings for the first bending direction and the second bending direction in this specification may have a certain error (e.g., angular offset within ±10°) in the directions described in each embodiment, and do not have to be strictly precise.

[0114] In some embodiments, the first bending direction of the first folding ring 7121 is different from the second bending direction of the second folding ring 7131, which can make the first pre-processed region 712 and the second pre-processed region 713 have stronger deformation capabilities along the vibration direction of the reinforcing region 711, thereby improving the vibration displacement or vibration amplitude provided by the pre-processed region to the reinforcing region 711 along the vibration direction of the reinforcing region 711.

[0115] In some embodiments, the projected area of ​​the second fold 7131 on a plane perpendicular to the vibration direction of the reinforcement region 711 can be smaller than the projected area of ​​the first fold 7121 on the same plane. This ensures that while the second fold 7131 increases the second displacement, the increase in the total projected area of ​​the second fold 7131 and the first fold 7121 along the reinforcement region 711 on the plane perpendicular to the vibration direction is small. The smaller total projected area of ​​the second fold 7131 and the first fold 7121 on the same plane allows the reinforcement region 711 to have a larger projected area on the same plane. This allows the reinforcement region 711 to drive more air vibration during vibration, thereby improving the low-frequency performance of the vibration assembly 700.

[0116] In some embodiments, the ratio of the projected area of ​​the second folded ring 7131 along the vibration direction of the reinforcing region 711 to the projected area of ​​the first folded ring 7121 along the vibration direction of the reinforcing region 711 can be 1:60-1:2. In some embodiments, the ratio of the projected area of ​​the second folded ring 7131 along the vibration direction of the reinforcing region 711 to the projected area of ​​the first folded ring 7121 along the vibration direction of the reinforcing region 711 can be 1:50-2:5. In some embodiments, the ratio of the projected area of ​​the second folded ring 7131 along the vibration direction of the reinforcing region 711 to the projected area of ​​the first folded ring 7121 along the vibration direction of the reinforcing region 711 can be 1:20-1:5.

[0117] In some embodiments, the dimensions (e.g., length dimension, height dimension) of the second fold 7131 along the second bending direction can be set to satisfy the second displacement amount provided by the second pre-processing region 713 to the reinforcement region 711 along the vibration direction of the reinforcement region 711.

[0118] In some embodiments, the height dimension of the projected shape of the second folded ring 7131 on a projection plane parallel to the vibration direction of the reinforcing region 711 can be 50µm-250µm. In some embodiments, the height dimension of the projected shape of the second folded ring 7131 on a projection plane parallel to the vibration direction of the reinforcing region 711 can be 80µm-200µm.

[0119] In some embodiments, the length of the second folded ring 7131 is defined as the dimension of its projected shape along the radial direction of its projected shape or the radial direction of the circumcircle of its projected shape on a projection plane parallel to the vibration direction of the reinforcement region 711. In some embodiments, the length of the second folded ring 7131 projected shape on a projection plane parallel to the vibration direction of the reinforcement region 711 can be 400µm-800µm. In some embodiments, the length of the second folded ring 7131 projected shape on a projection plane parallel to the vibration direction of the reinforcement region 711 can be 500µm-700µm.

[0120] In some embodiments, the ratio of the height to the length of the projected shape of the second folded ring 7131 on a projection plane parallel to the vibration direction of the reinforcing region 711 can be between 1:16 and 5:8. In some embodiments, the ratio of the height to the length of the projected shape of the second folded ring 7131 on a projection plane parallel to the vibration direction of the reinforcing region 711 can be between 1:8 and 1:2. In some embodiments, the ratio of the height to the length of the projected shape of the second folded ring 7131 on a projection plane parallel to the vibration direction of the reinforcing region 711 can be between 1:4 and 3:8.

[0121] In some embodiments, see Figure 14A When the second bending direction of the second fold ring 7131 is away from the center of the elastic element 710, the height dimension of the second fold ring 7131 along the second bending direction can be smaller than the length dimension along the perpendicular direction. This smaller height dimension allows the reinforcing region 711 to have a larger projected area on a plane perpendicular to the vibration direction of the reinforcing region 711. During vibration, the reinforcing region 711 can drive more air vibration, thereby improving the low-frequency performance of the vibration assembly 700.

[0122] In some embodiments, see Figures 7-15The ratio of the length of the second folded ring 7131 perpendicular to the second bending direction to the length of the reinforcing region 711 perpendicular to the vibration direction of the reinforcing region 711 can be between 1:20 and 8:25. In some embodiments, the ratio of the length of the second folded ring 7131 perpendicular to the second bending direction to the length of the reinforcing region 711 perpendicular to the vibration direction of the reinforcing region 711 can be between 1:15 and 4:15. In some embodiments, the ratio of the length of the second folded ring 7131 perpendicular to the vibration direction of the reinforcing region 711 to the length of the reinforcing region 711 perpendicular to the vibration direction of the reinforcing region 711 can be between 1:10 and 1:5. In some embodiments, the ratio of the length of the second folded ring 7131 perpendicular to the vibration direction of the reinforcing region 711 to the length of the reinforcing region 711 perpendicular to the vibration direction of the reinforcing region 711 can be between 1:8 and 1:6.

[0123] It should be noted that, in addition to the first pretreatment region 712 and the second pretreatment region 713, the elastic element 710 of the vibration assembly 700 may also include more pretreatment regions, for example, Figures 16-18 The third pretreatment region 715, the fourth pretreatment region 716, etc., are shown. The third pretreatment region 715 is connected to the periphery of the second pretreatment region 713, and the fourth pretreatment region 716 is connected to the periphery of the third pretreatment region 715. The number of pretreatment regions included in the elastic element 710 can be set according to the needs of the vibration assembly 700 (e.g., the amount of displacement provided by the pretreatment region to the reinforcement region 711 along the vibration direction of the reinforcement region 711), and the embodiments in this specification are not particularly limited here.

[0124] Figures 19-28 This is an exemplary structural diagram of a vibration assembly shown according to some embodiments of this specification.

[0125] In some embodiments, see Figures 19-28 One or more elements of the vibration assembly 1900 (e.g., elastic element 1910, reinforcing region 1911, first pretreatment region 1912, fixing region 1913, first folding ring 19121, etc.) and Figures 2-6 One or more elements of the vibration assembly 200 shown (e.g., elastic element 210, reinforcing region 211, first pre-treatment region 212, fixing region 213, first fold 2121, etc.) may be the same or similar. That is, the vibration assembly 1900 may include reinforcing region 1911, first pre-treatment region 1912, and fixing region 1913. The difference between the vibration assembly 1900 and the vibration assembly 200 lies in the support element 1920.

[0126] In some embodiments, see Figure 19The fixed region 1913 of the elastic element 1910 of the vibration assembly 1900 is located on the periphery of the first pretreatment region 1912 and is connected to the periphery of the first pretreatment region 1912. The support element 1920 can be located on any surface of the fixed region 1913 along the vibration direction of the reinforcement region 1911, and is connected to the first pretreatment region 1912 through the fixed region 1913.

[0127] In some embodiments, the support element 1920 may include a clamping portion 1921 and a deformation portion 1922. In some embodiments, the clamping portion 1921 may be disposed opposite to the deformation portion 1922, and a fixing region 1913 is clamped between the clamping portion 1921 and the deformation portion 1922 of the support element 1920. In some embodiments, the deformation portion 1922 of the support element 1920 may deform to provide a third displacement along the vibration direction of the reinforcement region 1911. The third displacement may be the magnitude of the displacement contributed by the support element 1920 to the vibration of the reinforcement region 1911 in its vibration direction. In some embodiments, such as Figure 19 As shown, the initial height of the deformable portion 1922 of the support element 1920 along the vibration direction of the reinforcing region 1911 (the height of the deformable portion 1922 when it is not deformed) is H0. When the deformable portion 1922 vibrates in response to the vibration signal of the vibration assembly 1900, the deformable portion 1922 can deform along the vibration direction of the reinforcing region 1911, such that the increase in height of the deformable portion 1922 along the vibration direction of the reinforcing region 1911 (i.e., the deformation amount of the deformable portion 1922) is H3. The increase in height of the deformable portion 1922 along the vibration direction of the reinforcing region 1911, H3, is the third displacement provided by the deformable portion 1922 to the reinforcing region 1911 along the vibration direction of the reinforcing region 1911.

[0128] In some embodiments, the deformation portion 1922 of the support element 1920 provides a third displacement H3 to the reinforcement region 1911 along the vibration direction of the reinforcement region 1911, which can be 1µm-50µm. In some embodiments, the deformation portion 1922 of the support element 1920 provides a third displacement H3 to the reinforcement region 1911 along the vibration direction of the reinforcement region 1911, which can be 4µm-30µm.

[0129] In some embodiments, by providing the deformation section 1922, the third displacement H3 provided by the support element 1920 to the reinforcement region 1911 along the vibration direction of the reinforcement region 1911 can be increased, thereby increasing the vibration displacement or vibration amplitude of the reinforcement region 1911 along the vibration direction of the reinforcement region 1911, thereby driving more air vibration and improving the low-frequency performance of the vibration assembly 1900. Simultaneously, when the vibration assembly 1900 vibrates, the first pre-treatment region 1912 and the support element 1920 store the vibration impact energy as deformation energy within themselves through deformation. The first pre-treatment region 1912 and the support element 1920 undergo multiple damping attenuation movements, thereby dissipating larger vibration impact energy through damping movements, preventing damage to the vibration assembly 1900 (especially the elastic element 1910) during vibration, and improving the reliability of the vibration assembly 1900.

[0130] In some embodiments, the support element 1920 may not include the clamping part 1921, and the fixing area 1913 of the elastic element 1910 may be directly connected to the deformable part 1922 (e.g., by adhesive).

[0131] In some embodiments, the ratio of a first displacement H1 provided by the first preprocessing region 1912 to the reinforcement region 1911 along the vibration direction of the reinforcement region 1911 and a third displacement H3 provided by the deformation portion 1922 to the reinforcement region 1911 along the vibration direction of the reinforcement region 1911 can be 1:50-50:1. In some embodiments, the ratio of the first displacement H1 to the third displacement H3 can be 1:1-2:1.

[0132] In some embodiments, the third displacement H3 provided by the support element 1920 to the reinforcement region 1911 along the vibration direction of the reinforcement region 1911 can be positively correlated with the elongation at break of the support element 1920 along the vibration direction of the reinforcement region 1911. In some embodiments, the greater the elongation at break of the support element 1920 along the vibration direction of the reinforcement region 1911, the greater the third displacement H3 provided by the support element 1920 to the reinforcement region 1911 along the vibration direction of the reinforcement region 1911. In some embodiments, the elongation at break of the support element 1920 along the vibration direction of the reinforcement region 1911 can be 5% to 800%. In some embodiments, the elongation at break of the support element 1920 along the vibration direction of the reinforcement region 1911 can be 10% to 600%. In some embodiments, the elongation at break of the support element 1920 along the vibration direction of the reinforcement region 1911 can be 50% to 400%.

[0133] In some embodiments, the support element 1920 provides a third displacement H3 along the vibration direction of the reinforcement region 1911 to the reinforcement region 1911, which may be negatively correlated with the hardness of the support element 1920. In some embodiments, the greater the hardness of the support element 1920, the smaller the third displacement H3 provided by the support element 1920 along the vibration direction of the reinforcement region 1911 to the reinforcement region 1911. In some embodiments, the hardness of the support element 1920 may be Shore A less than 90 degrees. In some embodiments, the hardness of the support element 1920 may be Shore A less than 80 degrees.

[0134] In some embodiments, the support element 1920 provides a third displacement H3 along the vibration direction of the reinforcement region 1911 to the reinforcement region 1911, which may be negatively correlated with the tensile strength of the support element 1920. In some embodiments, the greater the tensile strength of the support element 1920, the smaller the third displacement H3 along the vibration direction of the reinforcement region 1911 provided by the support element 1920. In some embodiments, the tensile strength of the support element 1920 may be 0.5 MPa to 100 MPa. In some embodiments, the tensile strength of the support element 1920 may be 1 MPa to 50 MPa. In some embodiments, the tensile strength of the support element 1920 may be 0.5 MPa to 10 MPa.

[0135] In some embodiments, in order to increase the third displacement H3 provided by the support element 1920 to the reinforcement region 1911 along the vibration direction of the reinforcement region 1911, the structure of the support element 1920 (especially the deformable part 1922) can be configured such that the cross-section of the support element 1920 perpendicular to the vibration direction of the reinforcement region 1911 has a different cross-sectional area along the vibration direction of the reinforcement region 1911, see details below. Figures 20-26 Related descriptions.

[0136] In some embodiments, when the cross-section of the support element 1920 perpendicular to the vibration direction of the reinforcing region 1911 has different cross-sectional areas along the vibration direction of the reinforcing region 1911, the third displacement H3 provided by the support element 1920 to the reinforcing region 1911 along the vibration direction of the reinforcing region 1911 can be 1µm-100µm. In some embodiments, when the cross-section of the support element 1920 perpendicular to the vibration direction of the reinforcing region 1911 has different cross-sectional areas along the vibration direction of the reinforcing region 1911, the third displacement H3 provided by the support element 1920 to the reinforcing region 1911 along the vibration direction of the reinforcing region 1911 can be 4µm-70µm. In some embodiments, when the cross-section of the support element 1920 perpendicular to the vibration direction of the reinforcing region 1911 has different cross-sectional areas along the vibration direction of the reinforcing region 1911, the third displacement H3 provided by the support element 1920 to the reinforcing region 1911 along the vibration direction of the reinforcing region 1911 can be 5µm-50µm.

[0137] In some embodiments, when the cross-section of the support element 1920 perpendicular to the vibration direction of the reinforcing region 1911 has a different cross-sectional area along the vibration direction of the reinforcing region 1911, the ratio of the first displacement H1 provided by the first pre-processing region 1912 to the reinforcing region 1911 along the vibration direction of the reinforcing region 1911 and the third displacement H3 provided by the deformation portion 1922 to the reinforcing region 1911 along the vibration direction of the reinforcing region 1911 can be 1:100-50:1. In some embodiments, the ratio of the first displacement H1 to the third displacement H3 can be 1:2-2:1.

[0138] In some embodiments, such as Figures 20-22 As shown, the support element 1920 can be a perforated structure. See also: [link to relevant documentation] Figure 20 The support element 1920 may include a first hole 19221 and a second hole 19222, which are located at the center of the interior of the support element 1920. The cross-sectional shape of the first hole 19221 and the second hole 19222 is elliptical in the direction of vibration parallel to the reinforcing region 1911. See also the following embodiments: Figure 21 The support element 1920 may include a third hole 19223, which is located inside the support element 1920 near the fixing region 1913. The cross-sectional shape of the third hole 19223 is arc-shaped in parallel with the vibration direction of the reinforcing region 1911. See also the following embodiments: Figure 22The support element 1920 may include a fourth hole 19224, which is located inside the support element 1920 away from the fixed region 1913. The cross-sectional shape of the fourth hole 19224 in the direction of vibration parallel to the reinforcement region 1911 is arc-shaped.

[0139] In some embodiments, by configuring the support element 1920 as a perforated structure, the deformation capability of the support element 1920 along the vibration direction of the reinforcement region 1911 can be improved, thereby increasing the third displacement H3 provided by the support element 1920 to the reinforcement region 1911 along the vibration direction of the reinforcement region 1911.

[0140] It should be noted that the number of holes, the location of the holes, the size of the holes, and the cross-sectional shape of the holes in the vibration direction parallel to the reinforcement region 1911 of the support element 1920 can be set according to the requirements of the support element 1920 (e.g., the size of the third displacement H3).

[0141] In some embodiments, see Figures 23-26 The inner and / or outer sides of the support element 1920 may have recesses 1923. See also, in some embodiments, [reference needed]. Figure 23 The recess 1923 of the support element 1920 is located inside the support element 1920, and the cross-sectional shape of the recess 1923 along the vibration direction of the reinforcing region 1911 is arc-shaped. The inner side of the support element 1920 refers to the side of the support element 1920 closest to the reinforcing region 1911. The side opposite to the inner side of the support element 1920 is the outer side of the support element 1920, which refers to the side of the support element 1920 furthest from the reinforcing region 1911. In some embodiments, see... Figure 24 The recess 1923 of the support element 1920 is located inside the support element 1920, and the cross-sectional shape of the recess 1923 along the vibration direction of the reinforcing region 1911 is square toothed. See also the following embodiments: Figure 25 The recess 1923 of the support element 1920 is located inside the support element 1920, and the cross-sectional shape of the recess 1923 along the vibration direction of the reinforcing region 1911 is tooth-shaped. In some embodiments, see... Figure 26 The recess 1923 of the support element 1920 is located on the inner and outer sides of the support element 1920, and the cross-sectional shape of the recess 1923 along the vibration direction of the reinforcement region 1911 is arc-shaped.

[0142] In some embodiments, by providing a recess 1923 on the side (inner and / or outer) of the support element 1920, the deformation capability of the support element 1920 along the vibration direction of the reinforcement region 1911 can be improved, thereby increasing the third displacement H3 provided by the support element 1920 to the reinforcement region 1911 along the vibration direction of the mass element 23210.

[0143] It should be noted that the position of the recess 1923 of the support element 1920, the number of recesses 1923, and the cross-sectional shape of the recess 1923 in the vibration direction parallel to the reinforcement region 1911 can be set according to the requirements of the support element 1920 (e.g., the size of the third displacement H3).

[0144] In some embodiments, see Figure 27 and Figure 28 The support element 1920 of the vibration assembly 1900 can be connected to the second pretreatment region 1914. Specifically, the fixing region 1913 of the elastic element 1910 is located on the periphery of the second pretreatment region 1914 and is connected to the periphery of the second pretreatment region 1914. The support element 1920 can be located on any surface of the fixing region 1913 along the vibration direction of the reinforcing region 1911, and is connected to the second pretreatment region 1914 through the fixing region 1913. The second pretreatment region 1914 can provide the reinforcing region 1911 with a second displacement along the vibration direction of the reinforcing region 1911.

[0145] In some embodiments, see Figure 27 The support element 1920 may not deform along the vibration direction of the reinforcing region 1911, meaning the support element 1920 may not provide a third displacement H3 along the vibration direction of the reinforcing region 1911. In this configuration, during the vibration of the vibration assembly 1900, the first pre-treatment region 1912 provides a first displacement H1 along the vibration direction of the reinforcing region 1911. The second pre-treatment region 1914 of the elastic element 1910 provides a second displacement H2 along the vibration direction of the reinforcing region 1911. The first displacement H1 and the second displacement H2 are superimposed to constitute the vibration displacement or vibration amplitude of the reinforcing region 1911 along the vibration direction of the reinforcing region 1911.

[0146] In some embodiments, see Figure 28The support element 1920 can deform along the vibration direction of the reinforcing region 1911, providing a third displacement H3 to the reinforcing region 1911 along the vibration direction. In this configuration, during the vibration of the vibration assembly 1900, the first pre-processing region 1912 of the elastic element 1910 provides a first displacement H1 to the reinforcing region 1911 along the vibration direction. The second pre-processing region 1914 of the elastic element 1910 provides a second displacement H2 to the reinforcing region 1911 along the vibration direction. The deformable portion 1922 of the support element 1920 provides a third displacement H3 to the reinforcing region 1911 along the vibration direction. The first displacement H1, the second displacement H2, and the third displacement H3 are superimposed to constitute the vibration displacement or vibration amplitude of the reinforcing region 1911 along the vibration direction.

[0147] In some embodiments, see Figures 27-28 The second pre-processing region 1914 provides a second displacement H2 along the vibration direction of the reinforcement region 1911 to the reinforcement region 1911, which may be the same as or different from the first displacement H1 along the vibration direction of the reinforcement region 1911 provided by the first pre-processing region 1912. See also: [link to previous text] Figures 27-28 The second pretreatment region 1914 (or the first pretreatment region 1912) provides the reinforcement region 1911 with a second displacement H2 (or a first displacement H1) along the vibration direction of the reinforcement region 1911, which can be 1µm-50µm. In some embodiments, see... Figures 27-28 The second pretreatment region 1914 (or the first pretreatment region 1912) provides the reinforcement region 1911 with a second displacement H2 (or a first displacement H1) along the vibration direction of the reinforcement region 1911, which can be 4um-30um.

[0148] In some embodiments, see Figure 28 The support element 1920 (deformation part 1922) provides a third displacement H3 along the vibration direction of the reinforcement region 1911 to the reinforcement region 1911, which can be 1µm-100µm. In some embodiments, see... Figure 28 The support element 1920 (deformation part 1922) provides a third displacement H3 along the vibration direction of the reinforcement region 1911 to the reinforcement region 1911, which can be 4µm-70µm. In some embodiments, see... Figure 28 The support element 1920 (deformation part 1922) provides a third displacement H3 along the vibration direction of the reinforcement region 1911 to the reinforcement region 1911, which can be 5um-50um.

[0149] In some embodiments, by providing a first pretreatment region 1912, a second pretreatment region 1914, and a support element 1920 (deformation part 1922) in the vibration assembly 1900, the vibration displacement or vibration amplitude (including a first displacement H1, a second displacement H2, and a third displacement H3) of the reinforcement region 1911 along the vibration direction of the reinforcement region 1911 can be increased. The increased vibration displacement or amplitude of the reinforcement region 1911 in its vibration direction serves two purposes. First, when the vibration assembly 1900 vibrates at a large amplitude, the first pre-treatment region 1912, the second pre-treatment region 1914, and the support element 1920 respectively store the vibration impact energy as deformation energy within their respective regions through deformation. These regions then undergo multiple damping attenuation movements, dissipating the large vibration impact energy and preventing damage to the vibration assembly 1900 (especially the elastic element 1910) during large-amplitude vibrations, thus improving the reliability of the vibration assembly 1900. Second, the increased vibration displacement or amplitude of the reinforcement region 1911 in its vibration direction allows it to drive more air vibration during vibration, thereby improving the low-frequency performance of the vibration assembly 1900.

[0150] Figure 29 This is an exemplary frame diagram of a loudspeaker according to some embodiments of this specification.

[0151] In some embodiments, the loudspeaker 2900 can be used to convert a signal containing sound information into mechanical vibration to generate sound. For example, the loudspeaker 2900 can generate a mechanical vibration signal based on an electrical signal, which can be transmitted to the outside of the loudspeaker to generate sound. In some embodiments, the loudspeaker 2900 can also generate mechanical vibration based on signals other than electrical signals, such as mechanical signals (e.g., pressure, mechanical vibration), light signals, heat signals, etc. In some embodiments, the loudspeaker 2900 can be a bone conduction loudspeaker, an air conduction loudspeaker, a bone-air conduction combined loudspeaker, etc. An air conduction loudspeaker is a loudspeaker in which sound waves are conducted through air. A bone conduction loudspeaker is a loudspeaker in which sound waves are conducted primarily through mechanical vibration in a solid (e.g., bone). In some embodiments, based on the working principle of the loudspeaker 2900, the loudspeaker 2900 can be classified as a moving-coil loudspeaker, a moving-iron loudspeaker, an electrostatic loudspeaker, a piezoelectric loudspeaker, etc.

[0152] In some embodiments, the speaker 2900 may include a housing 2910 and an acoustic driver 2920. The housing 2910 may be a regular or irregular three-dimensional structure with an internal acoustic cavity (i.e., a hollow portion). In some embodiments, the housing 2910 may be a hollow frame structure. In some embodiments, the hollow frame structure may include, but is not limited to, regular shapes such as rectangular frames, circular frames, and regular polygonal frames, as well as any irregular shape. In some embodiments, the housing 2910 may be made of metal (e.g., stainless steel, copper, etc.), plastic (e.g., polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), and acrylonitrile-butadiene-styrene copolymer (ABS), etc.), or composite materials (e.g., metal matrix composites or non-metal matrix composites). In some embodiments, the acoustic driver 2920 may be located within the acoustic cavity formed by the housing 2910 or at least partially suspended within the acoustic cavity of the housing 2910.

[0153] The acoustic actuator 2920 can be an acoustic device with energy conversion capabilities. In some embodiments, the acoustic actuator 2920 can convert electrical energy into mechanical energy, thereby generating sound. In some embodiments, the acoustic actuator 2920 can include a moving-coil acoustic actuator, a moving-iron acoustic actuator, an electrostatic acoustic actuator, or a piezoelectric acoustic actuator. In some embodiments, the moving-coil acoustic actuator can include a magnetic component that generates a magnetic field and a coil disposed in the magnetic field. When the coil is energized, it can vibrate in the magnetic field, thereby converting electrical energy into mechanical energy. This vibration can be further transmitted to the vibration component 2921, thereby generating sound. In some embodiments, the moving-iron acoustic actuator can include a coil that generates an alternating magnetic field and a ferromagnetic component disposed in the alternating magnetic field. The ferromagnetic component vibrates under the action of the alternating magnetic field, thereby converting electrical energy into mechanical energy. This vibration can be further transmitted to the vibration component 2921, thereby generating sound. In some embodiments, the electrostatic acoustic actuator can drive a diaphragm to vibrate through an electrostatic field disposed within it, thereby converting electrical energy into mechanical energy. In some embodiments, the piezoelectric acoustic actuator can convert electrical energy into mechanical energy through the electrostrictive effect of the piezoelectric material disposed therein. In some embodiments, the acoustic actuator 2920 can divide the cavity formed by the housing 2910 into a first cavity (also called the front cavity) and a second cavity (also called the back cavity or rear cavity). The sound generated by the acoustic actuator 2920 can radiate to the first cavity and / or the second cavity and be transmitted to the outside of the speaker 2900 through acoustic structures (e.g., one or more holes) on the housing 2910.

[0154] In some embodiments, the acoustic driver 2920 may include a vibration component 2921 and a drive unit 2922. In some embodiments, the vibration component 2921 may generate vibrations relative to the housing 2910 based on the drive of the drive unit 2922. The vibration component 2921 may be as described in the embodiments of this specification. Figures 1-28 Any of the vibration components shown. For example, vibration component 100, vibration component 200, vibration component 700, or vibration component 1900. In some embodiments, vibration component 2921 may be located within the acoustic cavity formed by housing 2910 or at least partially suspended in the acoustic cavity of housing 2910, and may be directly or indirectly connected to housing 2910.

[0155] In some embodiments, the vibration assembly 2921 may include an elastic element and a support element. The support element is connected to the housing 2910 to support the elastic element. In some embodiments, the elastic element may include a reinforcing region, one or more pre-treated regions, and a fixing region. The reinforcing region may be disposed in the center of the elastic element, one or more pre-treated regions may be disposed around the periphery of the reinforcing region, and the fixing region may be disposed around the periphery of the one or more pre-treated regions. In some embodiments, one or more pre-treated regions may provide one or more displacements along the vibration direction of the reinforcing region to the reinforcing region. In some embodiments, the deformation capacity of one or more pre-treated regions of the elastic element along the vibration direction of the reinforcing region may be greater than the deformation capacity of other regions of the elastic element (e.g., the reinforcing region). During vibration, one or more pre-treated regions may generate a large deformation along the vibration direction of the reinforcing region, such that one or more pre-treated regions may provide one or more displacements along the vibration direction of the reinforcing region to the reinforcing region. In some embodiments, the periphery of the vibration assembly 2911 is connected to the inner wall of the housing 2910, thereby dividing the cavity formed by the housing 2910 into a plurality of cavities including a first cavity and a second cavity. Specifically, the upper surface of the vibration assembly 2911 along the vibration direction of the reinforcement region (the surface away from the drive unit 2922) forms a first cavity with the housing 2910; the lower surface of the vibration assembly 2911 along the vibration direction of the reinforcement region (the surface away from the vibration assembly 2921) forms a second cavity with the housing 2910.

[0156] In some embodiments, the drive unit 2922 may be located on one side of the vibration assembly 2921 along the vibration direction of the reinforcement region. In some embodiments, the drive unit 2922 may be disposed inside the cavity formed by the housing 2910. In some embodiments, the drive unit 2922 may be connected to the vibration assembly 2921.

[0157] In some embodiments, the acoustic driver 2920 may further include a vibration transmission unit 2923. In some embodiments, the drive unit 2922 and the vibration transmission unit 2923 may be located on one side of the vibration assembly 2921 along the vibration direction of the reinforcement region. The vibration assembly 2921 (elastic element), the vibration transmission unit 2923, and the drive unit 2922 are arranged sequentially from top to bottom along the vibration direction of the reinforcement region. The two ends of the vibration transmission unit 2923 along the vibration direction of the reinforcement region are connected to the reinforcement region and the drive unit 2922, respectively.

[0158] In some embodiments, taking an air-conducting loudspeaker as an example, the driving unit 2922 can convert an electrical signal into a vibration signal, which is transmitted to the vibration component 2912 in the form of mechanical vibration through the vibration transmission unit 2923. The vibration component 2921 generates vibration and drives the air in the first cavity and / or the second cavity to vibrate, generating sound. The sound can be transmitted to the outside of the loudspeaker 2900 through the acoustic structure (e.g., one or more holes) on the housing 2910.

[0159] Figures 30-31 This is an exemplary structural diagram of a loudspeaker according to some embodiments of this specification.

[0160] In some embodiments, see Figure 30 The loudspeaker 3000 may include a housing 3010 and an acoustic driver 3020. The housing 3010 may be a regular or irregular three-dimensional structure with an internal acoustic cavity (i.e., a hollow portion). For example, it may be a hollow frame structure, including but not limited to regular shapes such as rectangular frames, circular frames, regular polygonal frames, and any irregular shape. The acoustic driver 3020 is located in the acoustic cavity formed by the housing 3010 or is at least partially suspended in the acoustic cavity of the housing 3010.

[0161] In some embodiments, the acoustic driver 3020 may include a vibration component 3021 and a driving unit 3022. In some embodiments, the driving unit 3022 may be connected to the vibration component 3021 to directly drive the vibration component 3021 to generate vibration. In some embodiments, the acoustic driver 3020 may include a vibration component 3021, a driving unit 3022, and a vibration transmission unit 3023. The vibration component 3021, the vibration transmission unit 3023, and the driving unit 3022 are arranged sequentially from top to bottom along the vibration direction of the vibration component 3021. The two ends of the vibration transmission unit 3023 along the vibration direction of the vibration component 3021 are respectively connected to the vibration component 3021 (reinforcement region) and the driving unit 3022, so that the driving unit 3022 can drive the vibration component 3021 to generate vibration through the vibration transmission unit 3023. In some embodiments, the periphery of the vibration component 3021 is connected to the inner wall of the housing 3010, thereby dividing the cavity formed by the housing 3010 into a plurality of cavities including a first cavity 3030 and a second cavity 3040. Specifically, the upper surface of the vibration component 3021 along its vibration direction (the surface away from the drive unit 3022) forms a first cavity 3030 with the housing 3010; the lower surface of the vibration component 3021 along its vibration direction (the surface away from the vibration component 3021) forms a second cavity 3040 with the housing 3010.

[0162] In some embodiments, one or more openings, such as a first opening 3011 and a second opening 3012, may be provided on the sidewalls of the housing 3010 corresponding to the first cavity 3030 and the second cavity 3040. The first cavity 3030 can communicate with the outside of the speaker 3000 through the first opening 3011. The second cavity 3040 can communicate with the outside of the speaker 3000 through the second opening 3012. In some embodiments, a damping mesh (e.g., a damping mesh 30121) may be provided on one or more openings (e.g., the second opening 3012). In some embodiments, the damping mesh can adjust (e.g., reduce) the amplitude of sound waves leaking from the openings, thereby improving the performance of the speaker 3000.

[0163] In some embodiments, the drive unit 3022 may be electrically connected to other components of the speaker 3000 (e.g., a signal processor) to receive electrical signals and convert them into mechanical vibration signals. These mechanical vibrations can be transmitted to the vibration assembly 3021 via the vibration transmission unit 3023, causing the vibration assembly 3021 to vibrate, thereby causing the air within the first cavity 3030 to vibrate and generate sound. In some embodiments, the sound may be transmitted to the outside of the speaker 3000 through a hole (e.g., a first hole 3011) on the housing 3010.

[0164] In some embodiments, the vibration assembly 3021 may include an elastic element 30211 and a support element 30212. See also Figure 30 The support element 30212 can be embedded in the inner wall of the housing 3010 and connected to the housing 3010 to support the elastic element 30211. When the support element 30212 is embedded in the inner wall of the housing 3010, the inner wall of the housing 3010 can be provided with a hole that matches the support element 30212, so that the support element 30212 can be placed in the hole to achieve the embedding of the support element 30212. In some embodiments, see Figure 31 The support element 30212 can also be disposed within the cavity formed by the housing 3010. The lower surface (surface near the drive unit 3022) or peripheral side of the support element 30212 along the vibration direction of the vibration assembly 3021 is connected to the housing 3010 to support the elastic element 30211. When the support element 30212 is disposed within the cavity formed by the housing 3010, the inner wall of the housing 3010 can be configured to have a protruding structure that matches the support element 30212, so that the support element 30212 can be disposed on the surface of the protruding structure along the vibration direction to achieve the connection between the support element 30212 and the housing 3010. In this configuration, by disposing of the support element 30212 within the cavity formed by the housing 3010, damage to the support element 30212 during the use of the speaker 3000 can be prevented, thereby preventing damage to the speaker 3000 (especially the vibration assembly 3021).

[0165] In some embodiments, see Figures 30-31 The elastic element 30211 may include a reinforcing region 30211A, a first pre-processing region 30211B, and a fixing region 30211C. The reinforcing region 30211A may be disposed in the middle of the elastic element 30211, the first pre-processing region 30211B may be disposed around the periphery of the reinforcing region 30211A, and the fixing region 30211C may be disposed around the periphery of the first pre-processing region 30211B. In some embodiments, the first pre-processing region 30211B may provide the reinforcing region 30211A with a first displacement along the vibration direction of the reinforcing region 30211A.

[0166] In some embodiments, the vibration component 3021 (reinforcement region 30211A) can change the volume of the first cavity 3030 during vibration. In some embodiments, the speaker 3000 can be a small-sized MEMS speaker or a miniature speaker. In some embodiments, the greater the vibration displacement or vibration amplitude of the reinforcement region 30211A along the vibration direction of the reinforcement region 30211A, the greater the change in volume of the first cavity 3030 (i.e., the stronger the air vibration within the first cavity 3030), and the better the low-frequency performance of the speaker 3000 (e.g., the greater the low-frequency sensitivity).

[0167] In some embodiments, the structure of the vibration assembly 3021 (elastic element 30211, support element 30212) can be designed to improve the vibration displacement or vibration amplitude of the reinforcement region 30211A along the vibration direction of the reinforcement region 30211A. See also [other embodiments]. Figures 30-31 The elastic element 30211 of the vibration assembly 3021 may include a first pre-treatment region 30211B, which may include a first folded ring having a first bending direction. During vibration of the elastic element 30211, the first folded ring can deform, causing the first pre-treatment region 30211B to provide a first displacement along the vibration direction of the reinforcement region 30211A, thereby increasing the vibration amplitude or vibration displacement of the reinforcement region 30211A along its vibration direction. For details regarding the first pre-treatment region 30211B and the first folded ring, please refer to other descriptions in this specification.

[0168] In some embodiments, the elastic element 30211 of the vibration assembly 3021 may further include a second pre-treatment region (not shown). The second pre-treatment region may surround the periphery of the first pre-treatment region 30211B, and the second pre-treatment region may provide a second displacement along the vibration direction of the reinforcement region 30211A. In some embodiments, the second pre-treatment region may include a second fold, which has a second bending direction. The second bending direction may be the same as or different from the first bending direction. The second fold may deform during the vibration of the elastic element 30211, causing the second pre-treatment region to provide a second displacement along the vibration direction of the reinforcement region 30211A, thereby increasing the vibration amplitude or vibration displacement of the reinforcement region 30211A along the vibration direction of the reinforcement region 30211A. For details regarding the second pre-treatment region and the second fold, please refer to other descriptions in this specification.

[0169] In some embodiments, the elastic element 30211 of the vibration assembly 3021 may further include more pre-processing regions, such as a third pre-processing region, a fourth pre-processing region, etc. The third pre-processing region is connected around the periphery of the second pre-processing region, and the fourth pre-processing region is connected around the periphery of the third pre-processing region. The number of pre-processing regions included in the elastic element 30211 can be set according to the requirements of the loudspeaker 3000 (e.g., low-frequency sensitivity), and the embodiments in this specification are not particularly limited herein.

[0170] In some embodiments, the structure of the support element 30212 can be designed to increase the vibration displacement or vibration amplitude of the reinforcement region 30211A along the vibration direction of the reinforcement region 30211A. In some embodiments, the support element 30212 may include a deformation portion 30212A, which has a certain deformation capability along the vibration direction of the reinforcement region 30211A. The deformation portion 30212A can provide a third displacement amount along the vibration direction of the reinforcement region 30211A by deforming. In some embodiments, the structure of the support element 30212 (e.g., a perforated structure, a recess, etc.) can be configured such that the cross-sectional area of ​​the support element 30212 in the direction perpendicular to the vibration direction of the reinforcing region 30211A has different cross-sectional areas. This increases the third displacement provided by the support element 30212 to the reinforcing region 30211A along the vibration direction of the reinforcing region 30211A, thereby increasing the vibration displacement or vibration amplitude of the reinforcing region 30211A along the vibration direction of the reinforcing region 30211A. For details regarding the support element 30212, please refer to other descriptions in this specification.
