Description

Technical Field

[0001] The present invention relates to an elastic structure design for tactile feedback and bone conduction audio output, and in particular to an internal and external connecting rib spring, a vibrator array device and applications thereof. Background Art

[0002] Conduction technology is an innovative method of transmitting sound to the inner ear through vibration, which is different from the traditional air conduction method (i.e., sound wave conduction outside the ear). Its working principle is based on the physiological characteristics of the human body and the law of sound wave propagation, and has unique application advantages and safety. The sound we hear is usually transmitted through the air outside the ear. The sound waves are transmitted to the eardrum through the external auditory canal, and then transmitted to the inner ear through the middle ear bones. Bone conduction technology directly uses the vibration of the skull and skull to transmit sound, bypassing the outer ear and middle ear and directly acting on the inner ear.

[0003] Bone conduction products usually work by first converting electroacoustic signals into mechanical vibrations, and then transmitting the vibrations to the inner ear area or tissue nerves through the internal bones of the human body by direct contact with the human body. Specifically, bone conduction products usually contain one or more vibration units (vibrators), which can be placed in various parts of the human body such as the head, neck, waist, etc., and can be used in the fields of tactile feedback, audio hearing, etc. When the relevant product is connected to an electrical signal or plays audio, the vibrator will generate corresponding mechanical vibrations, through which real tactile feedback can be achieved; at the same time, the vibrations can be quickly transmitted to the auditory nervous system of the inner ear through the bones of the head, neck, waist, etc., to form auditory perception.

[0004] The vibrator is usually composed of components such as magnets, coils and springs. Each component plays an important role in the vibration system; among them, the spring is particularly used to adjust and control the vibration behavior of the vibrator.

[0005] The natural frequency and amplitude of the oscillator are affected by the characteristics of the spring clip; in particular, the characteristics of the spring clip are affected by the spring clip connecting ribs. Through the design of the spring clip connecting ribs, the vibration behavior of the oscillator can be adjusted and controlled to adapt to different application scenarios.

[0006] The current shrapnel has a relatively simple design in terms of connecting ribs. First, the current shrapnel is usually designed with a single layer of connecting ribs. In some application scenarios such as vibrator arrays, it cannot provide sufficient rigid support. In addition, in the face of different vibration frequencies and amplitudes, the single layer of connecting ribs is difficult to flexibly adjust to meet the needs, which limits the versatility and expansibility of the shrapnel; the outer circle of the shrapnel is usually consistent with the outer circle of the vibrator outer cylinder, lacking the necessary extension part, making it difficult to effectively integrate into the vibrator array device and realize tactile feedback and audio hearing about various parts of the human body; secondly, the lack of an extension part on the outer circle also limits the size and shape of the contact surface between the shrapnel and the human body, thereby limiting the range and accuracy of tactile feedback. Finally, the shrapnel lacks the necessary suspension structure design. In application scenarios where fine tactile feedback is required for different parts of the human body, this design is difficult to meet the needs, affecting the propagation direction and range of sound, and reducing the immersion and realism of audio hearing. Therefore, we proposed an innovative shrapnel design that is fully suitable for the situation of close contact with human skin and vibrator arrays.

[0007] At present, the design of shrapnel mostly adopts a single-layer connecting rib structure. Although this design is simple, it seems to be somewhat inadequate in complex application environments. First, the load-bearing capacity, amplitude and adaptability of the single-layer connecting rib shrapnel are relatively limited, and it cannot provide sufficient rigid support, and it is difficult to meet the requirements of the vibrator array in terms of tactile feedback and audio hearing; secondly, the shrapnel circle is consistent with the outer circle of the vibrator outer cylinder, which limits the size and shape of the contact surface between the shrapnel and the human body, thereby limiting the range and accuracy of tactile feedback, making it difficult to apply the shrapnel to the vibrator array, and it is difficult to achieve effective tactile feedback and auditory perception.

[0008] There are also deficiencies in the way the shrapnel is connected to external entities or devices. First, the shrapnel lacks the necessary extension part on the outside, and there is no part to connect and fasten with other external real devices. It cannot be connected and fixed with the vibrator outer tube and the vibrator array device at the same time, and can only be connected and fixed with the vibrator outer tube; secondly, there is a lack of elastic suspension structure design, which leads to poor adaptability of the shrapnel, and it is difficult to adapt to the application scenarios such as tactile feedback and auditory feedback and the requirements of vibrator array application devices; when facing different pressures on different parts of the human body such as the head, neck, waist, etc., the relative position of the vibrator and the normal working environment cannot be guaranteed. During long-term use, the vibrator is prone to loosening, damage and other problems, affecting the service life, performance and practicality of the product. Summary of the invention

[0009] The present invention is aimed at the above technical problems. In order to solve the above problems, we propose an innovative spring design.

[0010] To achieve the above object, the present invention provides the following technical solutions:

[0011] An inner and outer connecting rib spring piece, comprising:

[0012] A spring body, wherein the spring body has an inner ring and an outer ring;

[0013] At least two inner connecting ribs are arranged on the inner circle of the spring body and are used for hard contact and tight fit connection with the outer cylinder of the vibrator;

[0014] At least two external connection ribs, disposed between the inner ring and the outer ring of the spring body, for connecting with an external environment or device;

[0015] Among them, the inner connecting ribs and the outer connecting ribs are distributed on the spring body in a rotationally symmetrical or mirror-symmetrical manner, the rotation directions of the inner connecting ribs and the outer connecting ribs can be the same or opposite, and the rotation angle between the inner connecting ribs and the outer connecting ribs is between 0° and 360°.

[0016] Specifically, the shape of the shrapnel body is one of circular, fan-shaped, rectangular or racetrack-shaped.

[0017] Specifically, the spring body is made of metal material, and the metal material is stainless steel or titanium alloy.

[0018] Specifically, the spring sheet body further includes one or more positioning holes or positioning grooves for fixing the spring sheet on an external environment or device.

[0019] Specifically, the hollowed-out parts of the inner connecting ribs and their cross-sectional shapes are uniformly distributed inside the inner circle of the spring body in a rotationally symmetrical or mirror-symmetrical manner to avoid mutual interference between the connecting ribs during vibration.

[0020] Specifically, the hollowed-out portion of the external connecting rib and its cross-sectional shape are evenly distributed between the outer ring and the inner ring of the spring body in a rotationally symmetrical or mirror-symmetrical manner to ensure that the external connecting rib can effectively disperse and withstand external stress during the deformation of the spring.

[0021] A vibrator array device, comprising: at least one internal and external connecting rib spring piece according to any one of claims 1 to 6;

[0022] A vibrator connected to the inner and outer connecting rib springs;

[0023] A soft silicone bracket for supporting the inner and outer connecting rib springs and the vibrator;

[0024] A dust cover disposed above the vibrator;

[0025] Among them, the inner and outer connecting rib springs are connected to the outer tube of the vibrator through their inner connecting ribs, and are connected to the soft silicone bracket through their outer connecting ribs to form an elastic suspension system, so that the vibrator can adapt to the pressure of different parts of the human body such as the head, neck, waist, etc.

[0026] Specifically, the vibrators are evenly distributed on the soft silicone support in an array of 1 row and 2 columns, 2 rows and 2 columns, or 2 rows and 3 columns, wherein:

[0027] When there are 1 row and 2 columns, the left vibrator is left surround and the right vibrator is right surround;

[0028] When there are 2 rows and 2 columns, the leftmost group is left surround, and the rightmost group is right surround;

[0029] When there are 2 rows and 3 columns, the leftmost group is the left surround, the rightmost group is the right surround, and the middle group is the low-frequency effect.

[0030] Specifically, the dust cover is a curved convex shape or a flat shape, which is used to provide support and reserve enough space for the vibrator to vibrate.

[0031] A method for applying an internal and external connection rib spring piece comprises the following steps: obtaining the internal and external connection rib spring piece;

[0032] Connecting the inner connecting rib of the inner and outer connecting rib spring piece to the outer cylinder of the vibrator;

[0033] Connecting the outer connecting ribs of the inner and outer connecting rib springs to the soft silicone bracket;

[0034] A dust cover is provided above the vibrator;

[0035] Arranging a plurality of the vibrators in a predetermined array on the soft silicone support to form a vibrator array device;

[0036] The vibrator array device is applied to tactile feedback or bone conduction audio output devices, including but not limited to: sleeping pads, pillows, head wearable devices, sofas, massage chairs, vehicle backrests, vehicle pillows, vests, belts, leggings, helmets, hats, neck massagers, leg massagers, foot massagers, abdominal massagers or chest massagers.

[0037] Considering that the shrapnel needs to be suitable for application scenarios where it is close to the human head, back, waist and even the soles of the feet, especially in the case of waist application, the human body lies directly on the vibrator array. This close contact puts higher requirements on the vibration performance of the vibrator. In order to ensure that the vibrator can still vibrate normally even when it is under external pressure, we designed a unique suspension system, which consists of two core components:

[0038] Support structure: A soft silicone bracket with an array opening design is used as the base, and the vibrator is fixed in the hole in an elastic suspension state by connecting to a larger elastic structure.

[0039] Elastic structure: The vibrator body is not directly fixed on the support bracket, but is suspended by an innovatively designed elastic structure. This design allows the vibrator to maintain an elastic suspension state, and when encountering external pressure of different intensities, the relative position of the vibrator in the hole is adaptively adjusted, thereby effectively alleviating the problem of reduced vibration performance caused by uneven external pressure. At the same time, the elastic structure also greatly enhances the amplitude and vibration performance of the vibrator, allowing the vibrator array device to more effectively transmit vibration energy to various parts of the human body, enhancing the tactile and auditory vibration experience.

[0040] At the same time, in order to achieve the above innovative design, we have made a new transformation to the spring structure and introduced the spring design concept based on internal and external connecting ribs. This design combines traditional springs with elastic structural parts, which not only simplifies the manufacturing process, but also significantly improves the overall performance and reliability of the vibrator array.

[0041] The newly designed shrapnel combines the traditional shrapnel with the elastic structural parts, so that the vibrator can be fixed in the vibrator array device in an elastic suspension state; the internal and external connecting rib shrapnel cooperate with the soft silicone bracket so that the vibrator can always adaptively adjust its relative position when facing pressure from different parts of the human body such as the head, back, waist, etc., to ensure its own vibration performance.

[0042] The flat body of the newly designed shrapnel is made of metal materials, such as stainless steel and titanium alloy, to enhance its elasticity and shape memory properties. Metal materials can maintain stable performance under different temperature and stress conditions, and can quickly return to the original shape after multiple deformations, ensuring the long-term use of the shrapnel.

[0043] In terms of internal connecting ribs, the new design uses a combination of multiple cross-sectional shapes and sizes to adapt to different stress distribution conditions and meet the connection requirements between the spring and the vibrator outer cylinder and other devices. The number and distribution position of the internal connecting ribs are also different to ensure that the spring can be evenly distributed when subjected to force to avoid excessive local stress.

[0044] In terms of external connecting ribs, the new design adopts more flexible connection methods, such as welding, screw connection, riveting, etc., to adapt to the connection requirements of different external environments or devices. The cross-sectional shape and distribution position of the external connecting ribs are also different to ensure that the external stress can be effectively dispersed and borne during the deformation of the spring piece, protecting the main part from damage due to excessive stress, and avoiding interference with the internal connecting ribs.

[0045] The newly designed spring clip also includes a plurality of positioning holes or positioning grooves, which can well ensure that the spring clip is accurately and stably fixed on a specific entity or device. At the same time, the design of the positioning holes or positioning grooves also takes into account the installation method and disassembly convenience of other connecting parts, which is convenient for subsequent maintenance and replacement work.

[0046] In short, the newly designed spring clip based on internal and external connecting ribs has been optimized and innovated in terms of materials, structure, connection methods, etc., so as to meet the requirements of more complex and special application scenarios. The new design can not only improve the performance and life of the spring clip, but also improve the comfort and versatility of the product.

[0047] The present invention has the following beneficial effects:

[0048] 1. The newly designed spring clip combines the traditional spring clip with the elastic structural part, so that the vibrator can be fixed in the vibrator array device in an elastic suspension state; the internal and external connecting rib spring clips cooperate with the soft silicone bracket so that the vibrator can always adaptively adjust its relative position when facing the pressure of different parts of the human body such as the head, back, waist, etc., to ensure its normal operation and vibration performance. At the same time, the distribution layout and cross-sectional design of the internal and external connecting ribs also ensure the deformation uniformity and reset accuracy of the spring clip during the vibration process, avoiding the mutual interference of the internal and external connecting ribs;

[0049] 2. The newly designed spring clips are made of high-performance metal materials, such as stainless steel and titanium alloy, which not only have excellent elasticity and shape memory properties, but also maintain stable performance under different temperature and stress conditions. This means that the spring clips can work in a wider range of temperature and stress, and are suitable for more complex and special application scenarios;

[0050] 3. The newly designed springs use more flexible connection methods, such as screw connection, snap connection, etc. These connection methods can adapt to the connection requirements of different external environments or devices. At the same time, the design of the positioning holes or positioning slots also takes into account the convenience of installation and disassembly of the connectors, making it convenient for users to maintain and replace them. This improvement in flexibility and convenience not only reduces the user's maintenance cost and time cost, but also improves the product's efficiency and lifespan;

[0051] 4. The newly designed internal and external connecting rib shrapnel has higher versatility and adaptability in structure and function. Compared with the shrapnel with single-layer connecting ribs, the internal and external connecting rib shrapnel is undoubtedly more suitable for the vibrator array. Whether in consumer electronic products such as smartphones, tablets, game controllers, or in the fields of virtual reality, medical equipment, etc., the newly designed shrapnel can better play an excellent performance and role. This improvement in versatility and adaptability makes the newly designed shrapnel more competitive and has a stronger application prospect in the market.

[0052] In summary, the newly designed spring clip based on internal and external connecting ribs shows significant advantages and benefits in terms of connection stability, mechanical vibration performance, material properties, connection method and adaptability, and can better match the requirements of the vibrator array in tactile feedback and audio hearing.

[0064] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, the specific features, structures or characteristics of one or more embodiments can be combined in any suitable form.

[0065] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0066] The present invention relates to an internal and external connecting rib spring, a vibrator array device and applications thereof, and in particular to an elastic structure design for tactile feedback and bone conduction audio output.

[0067] like Figure 1-12As shown, the present invention provides an inner and outer connecting rib spring piece, comprising a spring piece body, an inner connecting rib 20 and an outer connecting rib 30. The spring piece body has an inner ring 11 and an outer ring 12. The inner connecting rib 20 is arranged on the inner ring 11 of the spring piece body, and is used for hard contact and tight fit connection with the vibrator outer cylinder 40. The outer connecting rib 30 is arranged between the inner ring 11 and the outer ring 12 of the spring piece body, and is used for connection with an external environment or device.

[0068] Preferably, the inner connecting rib 20 and the outer connecting rib 30 are distributed on the spring body in a rotationally symmetrical or mirror-symmetrical manner. This symmetrical distribution can ensure that the spring can deform evenly when subjected to force and avoid local stress concentration. The rotation directions of the inner connecting rib 20 and the outer connecting rib 30 can be the same or opposite. In order to achieve different vibration characteristics, the rotation angle between the inner connecting rib 20 and the outer connecting rib 30 can be adjusted between 0° and 360°. For example, when the inner connecting rib 20 and the outer connecting rib 30 rotate in the same direction, a larger amplitude can be generated; when the rotation directions are opposite, more precise vibration control can be achieved.

[0069] In order to adapt to different application scenarios, the shape of the spring body can be designed to be one of circular, fan-shaped, rectangular or racetrack-shaped. For example, the circular design is suitable for all-round balanced vibration requirements, while the rectangular design is more suitable for linearly arranged vibrator arrays.

[0070] The shrapnel of the present invention is made of metal material, preferably stainless steel or titanium alloy. These materials have excellent elasticity and shape memory properties, and can maintain stable performance under different temperature and stress conditions. For example, the elastic modulus of stainless steel is about 200GPa, and it can maintain stable mechanical properties in the temperature range of -20°C to 150°C.

[0071] In order to facilitate installation and fixing, the spring body also includes one or more positioning holes 13 or positioning grooves. These positioning structures can be flexibly set according to the needs of specific application scenarios, and are usually between 2mm and 5mm in diameter to meet the needs of different connectors.

[0072] The design of the inner connecting rib 20 is particularly critical. Its hollowed-out portion and cross-sectional shape are evenly distributed inside the inner ring 11 of the spring body in a rotationally symmetrical or mirror-symmetrical manner. This design can avoid mutual interference between the connecting ribs during vibration and improve the durability of the spring. For example, in one embodiment, the cross-section of the inner connecting rib 20 can be designed as a "T" shape, in which the width of the transverse portion is 1.5 mm and the length of the longitudinal portion is 2 mm, so that the vibration freedom can be maximized while ensuring strength.

[0073] Equally important is the design of the external connecting rib 30. Its hollowed-out portion and cross-sectional shape are also evenly distributed between the outer ring 12 and the inner ring 11 of the spring body in a rotationally symmetrical or mirror-symmetrical manner. This design ensures that the external connecting rib 30 can effectively disperse and withstand external stress during the spring deformation process. For example, the external connecting rib 30 can adopt a gradual cross-sectional design, with a width of 1 mm near the inner ring 11 and gradually increasing to 2 mm near the outer ring 12, so that uniform distribution of stress can be achieved.

[0074] Based on the above-mentioned internal and external connecting rib springs, the present invention also provides a vibrator array device. Figure 2 As shown, the device includes at least one of the above-mentioned internal and external connecting rib springs, a vibrator 1 connected to the spring, a soft silicone bracket 50 for supporting the spring and the vibrator, and a dust cover 60 arranged above the vibrator 1.

[0075] In this structure, the inner and outer connecting rib springs are connected to the outer tube 40 of the vibrator 1 through the inner connecting rib 20, and are connected to the soft silicone bracket 50 through the outer connecting rib 30, thereby forming an elastic suspension system. This design enables the vibrator 1 to adapt to the pressure of different parts of the human body, such as the head, neck, and waist. For example, when applied to the head, the elastic suspension system can adapt to the curved surface of the head to ensure good contact between the vibrator 1 and the skin; when applied to the waist, the system can withstand greater pressure without affecting the performance of the vibrator 1.

[0076] The arrangement of the vibrators 1 on the soft silicone support 50 is also an important feature of the present invention. According to different application requirements, the vibrators 1 can be evenly arranged on the soft silicone support 50 in an array of 1 row and 2 columns, 2 rows and 2 columns, or 2 rows and 3 columns. Each arrangement has its specific purpose:

[0077] 1.1 row 2 columns: suitable for neck or behind the ear. The left vibrator is the left surround, and the right vibrator is the right surround, which can achieve a stereo effect.

[0078] 2.2 rows and 2 columns: suitable for back or chest applications. The leftmost group is the left surround, and the rightmost group is the right surround, which can provide a wider sound field.

[0079] 3.2 rows and 3 columns: suitable for waist or large area applications. The leftmost group is left surround, the rightmost group is right surround, and the middle group is low-frequency effect, which can achieve a full range of sound and tactile experience.

[0080] The design of the dust cover 60 has also been carefully considered. It can be a curved convex shape or a flat shape, mainly used to provide support and reserve enough space for the vibrator 1 to vibrate. For example, the curved convex shape is suitable for fitting with the curved surface of the human body, while the flat shape is suitable for embedding in a flat device. The height of the dust cover 60 is usually between 2mm and 5mm, so as to protect the vibrator 1 without affecting the lightness and thinness of the overall device.

[0081] Finally, the present invention also provides a method for applying the internal and external connecting rib springs. The method comprises the following steps:

[0082] Step S1: obtaining the above-mentioned inner and outer connecting rib spring pieces.

[0083] Step S2: Connect the inner connection rib 20 of the inner and outer connection rib springs to the vibrator outer cylinder 40. This step can be achieved by welding, snap fastening or screw fixing, etc. The specific selection depends on the requirements of the application scenario.

[0084] Step S3: Connect the outer connection rib 30 of the inner and outer connection rib springs to the soft silicone bracket 50. This step is usually fixed by screws to facilitate later maintenance and replacement.

[0085] Step S4: a dust cover 60 is provided on the vibrator 1. The dust cover 60 can be fixed by snapping or bonding to ensure that it will not fall off during use.

[0086] Step S5: Arrange multiple vibrators 1 in a predetermined array on the soft silicone support 50 to form a vibrator array device. This step requires selecting a suitable array mode according to the specific application scenario, such as 1 row and 2 columns, 2 rows and 2 columns, or 2 rows and 3 columns as described above.

[0087] Step S6: Apply the formed vibrator array device to a tactile feedback or bone conduction audio output device. These devices may include but are not limited to: a sleeping pad, a pillow, a head-worn device (such as an AR / VR device, an eye mask, a forehead wearer, headphones, glasses), a sofa, a massage chair, a vehicle backrest, a vehicle pillow, a vest, a belt, a leggings, a helmet, a hat, a neck massager, a leg massager, a foot massager, an abdominal massager, or a chest massager.

[0088] During the application process, the working parameters of the vibrator 1 can be adjusted according to the needs of different devices. For example, for sleep monitoring equipment, the working frequency of the vibrator 1 can be set between 20Hz-40Hz to provide slight but perceptible tactile feedback; while for music appreciation equipment, the frequency range can be expanded to 20Hz-20kHz to cover the audible range of the human ear.

[0089] In summary, the present invention provides a highly adaptable and high-performance solution for the field of tactile feedback and bone conduction audio output through the innovative design of internal and external connecting ribs and springs, combined with the flexible configuration of the vibrator array device. This design not only improves the comfort of the device, but also greatly expands its application range, opening up new possibilities for the development of future smart wearable devices and human-computer interaction technology.

[0090] Example 1: Sector-shaped + 3 inner connecting ribs + 3 outer connecting ribs

[0091] This embodiment shows a unique fan-shaped spring design. Figure 2 As shown, the spring piece includes a spring piece body, which has two main parts, an inner ring 11 and an outer ring 12. The inner ring 11 is connected by three inner connecting ribs 20, and the outer ring 12 is connected by three outer connecting ribs 30. The characteristic of this design is that the inner connecting ribs 20 and the outer connecting ribs 30 are evenly distributed in the spring piece body in a 120° rotationally symmetrical manner.

[0092] It is worth noting that the rotation directions of the inner connecting rib 20 and the outer connecting rib 30 are opposite. Specifically, the inner connecting rib 20 rotates in a clockwise direction, while the outer connecting rib 30 rotates in a counterclockwise direction. This counter-rotation design is of great significance: it can generate a balanced torque during the vibration process, which helps to reduce unnecessary torsional deformation, thereby improving the accuracy and efficiency of the vibration.

[0093] The design of the inner ring 11 includes welding openings 15, which are mainly used for connection with the vibrator outer cylinder 40. The connection method adopts a combination of buckles and welding. This dual fixing method has its unique advantages: the buckle provides the convenience of quick installation and disassembly, while welding ensures the stability and reliability of the connection during long-term use. This combination method not only improves the service life of the product, but also facilitates later maintenance and replacement.

[0094] The outer ring 12 is designed with positioning holes 13. The main function of these positioning holes 13 is to fasten the spring body and the vibrator 1 to the external device through screws. The advantage of this design is that it provides great flexibility, so that the spring can be adapted to a variety of different application scenarios. For example, in a head wearable device, the spring can be fixed to the headband through these positioning holes 13; in a car backrest, the spring can be fixed to the seat frame. At the same time, the screw connection also allows fine-tuning during use to optimize the vibration effect and comfort.

[0095] Another advantage of the fan-shaped design is that it can achieve directional vibration control in a limited space. This is very useful in certain specific applications. For example, in headphones, fan-shaped springs can be used to precisely control the directionality of sound, thereby improving the audio experience.

[0096] Example 2: Circular + 3 inner connecting ribs + 3 outer connecting ribs (reverse direction)

[0097] Please refer to Figure 3 This embodiment shows a circular spring design, and its basic structure is similar to that of embodiment 1, but the shape of the spring body is changed from a fan shape to a circle. This circular design may be more suitable in some application scenarios, such as when all-round balanced vibration is required.

[0098] Similarly, the spring body is also divided into two main parts: the inner ring 11 and the outer ring 12. The inner ring 11 is connected by three inner connecting ribs 20, and the outer ring 12 is connected by three outer connecting ribs 30. The inner connecting ribs 20 and the outer connecting ribs 30 are still evenly distributed on the spring body with 120° rotational symmetry. This symmetrical distribution ensures the uniform transmission of vibration force, helps to reduce local stress concentration, and prolongs the service life of the spring.

[0099] Similar to Example 1, the inner connecting rib 20 rotates in a clockwise direction and the outer connecting rib 30 rotates in a counterclockwise direction. This counter-rotation design can also provide a good torque balance in a circular spring. In a circular design, this balance is particularly important because it can ensure the consistency of vibration in all directions, thereby providing a more uniform and stable tactile feedback or audio output.

[0100] The welding opening 15 of the inner ring 11 is mainly used to connect with the vibrator outer cylinder 40 by snapping and welding. This connection method is also effective in the circular design, which can ensure a stable connection between the vibrator 1 and the spring body. One advantage of the circular design is that it can more easily achieve 360-degree rotation adjustment of the vibrator 1, which is very useful in some applications that require precise control of the vibration direction.

[0101] The positioning holes 13 of the outer ring 12 are designed to fasten the spring body and the vibrator 1 to an external device by screws. In a circular design, these positioning holes 13 are usually evenly distributed on the outer ring 12. This distribution method can ensure the uniformity of the fixing force and further improve the stability of the entire device.

[0102] Another advantage of the circular design is that it has better spatial adaptability. In space-constrained applications such as smart watches or small portable devices, circular springs can more effectively utilize limited space while ensuring that vibration performance is not affected.

[0103] In general, the two designs each have their own advantages and applicable scenarios. The fan-shaped design is suitable for applications that require directional control, while the circular design is more suitable for scenarios that require all-round balanced vibration. Both designs make full use of the innovative structure of the internal and external connecting ribs to provide flexible solutions for different application requirements.

[0104] Example 3: Circular + 3 inner connecting ribs + 3 outer connecting ribs (same direction)

[0105] Please refer to Figure 4 This embodiment shows another circular spring clip design. The spring clip body is still divided into two main parts: an inner ring 11 and an outer ring 12. The inner ring 11 is connected by three inner connecting ribs 20, and the outer ring 12 is connected by three outer connecting ribs 30. The inner connecting ribs 20 and the outer connecting ribs 30 are evenly distributed on the spring clip body with 120° rotational symmetry.

[0106] Different from the previous two embodiments, the inner connecting rib 20 and the outer connecting rib 30 in this embodiment both rotate in a clockwise direction. This same-direction rotation design may produce unique vibration characteristics in certain specific applications, such as in scenarios where a larger amplitude is required.

[0107] The inner ring 11 is designed with a welding opening 15, which is connected to the vibrator outer cylinder 40 mainly by snapping and welding. The outer ring 12 is designed with a positioning hole 13, and the screw fastens the spring body and the vibrator 1 to the external device through the positioning hole 13. This design continues to ensure the applicability and performance stability of the circular spring in various application scenarios.

[0108] Example 4: Rectangle + 2 inner connecting ribs + 2 outer connecting ribs

[0109] Please refer to Figure 5 This embodiment introduces a rectangular spring design, showing the diversity of the spring body shape. The spring body is also divided into an inner ring 11 and an outer ring 12, but the number and distribution of the connecting ribs are changed.

[0110] The inner ring 11 is connected by two inner connecting ribs 20, and the outer ring 12 is connected by two outer connecting ribs 30. The inner connecting ribs 20 and the outer connecting ribs 30 are evenly distributed in the spring body in a 180° rotationally symmetrical manner. This design is suitable for application scenarios that require a large amplitude in a certain axial direction.

[0111] It is worth noting that the inner connecting rib 20 rotates in a counterclockwise direction, while the outer connecting rib 30 rotates in a clockwise direction. This counter-rotation design may help balance the moment in the rectangular structure and reduce unnecessary twisting.

[0112] The inner ring 11 is designed with a positioning and welding opening 15, and is connected to the vibrator outer cylinder 40 mainly by screw connection and welding. This double connection method enhances the stability of the structure. The outer ring 12 is designed with a positioning hole 13, and the screw fastens the spring body and the vibrator 1 to the external device through the positioning hole 13.

[0113] Example 5: Track shape + 4 inner connecting ribs + 4 outer connecting ribs

[0114] Please refer to Figure 6 This embodiment shows a track-shaped spring clip design, which further expands the shape diversity of the spring clip body. The spring clip body is still divided into an inner ring 11 and an outer ring 12, but the number of connecting ribs is increased to 4.

[0115] The inner ring 11 is connected by four inner connecting ribs 20, and the outer ring 12 is connected by four outer connecting ribs 30. The four outer connecting ribs 30 are evenly distributed on the outer ring 12 of the spring body in a mirror-symmetrical manner, and the four inner connecting ribs 20 are also evenly distributed on the inner ring 11 of the spring body in a mirror-symmetrical manner. This design combines the balance of a circle and the linear characteristics of a rectangle, and is suitable for applications that need to extend in a certain direction, such as back or leg equipment.

[0116] The inner ring 11 is designed with a bayonet and a welding opening, and is connected to the vibrator outer cylinder 40 mainly by means of a snap connection and welding. This multiple connection method further enhances the stability of the structure. The outer ring 12 is designed with a positioning hole 13, and a screw fastens the spring body and the vibrator 1 to the external device through the positioning hole 13.

[0117] Example 6 1 row 2 column transducer array

[0118] Please refer to Figure 7 This embodiment shows a 1-row 2-column vibrator array device. The circular spring body 16 is connected and fixed to the vibrator outer cylinder 40 by welding, and then fixed to the soft silicone bracket 50 by screw connection.

[0119] The vibrators 1 are evenly distributed on the soft silicone bracket 50 in an array of 1 row and 2 columns. A dust cover 60 with a curved convex surface is set above each vibrator 1. The advantage of this design is that when the human body is pressed against the vibrator array, the internal and external connecting rib springs and the soft silicone bracket 50 can undergo elastic deformation and fit closely to the human body; at the same time, the dust cover 60 provides support and reserves enough space for the vibration of the vibrator 1.

[0120] When the vibrator 1 is working, the circular spring body performs reciprocating mechanical vibrations under the traction of the inner connecting rib 20 and the outer connecting rib 30, thereby achieving the purpose of touch feedback. At the same time, the vibration is transmitted along the bones to the ear to realize auditory perception, wherein the left vibrator 1 is the left surround and the right vibrator 1 is the right surround, thereby achieving a stereo effect.

[0121] Example 72 rows and 3 columns of vibrator array + circular spring

[0122] Please refer to Figure 8This embodiment shows a 2-row 3-column vibrator array device, using a circular spring body. The circular spring body 16 is connected and fixed to the vibrator outer cylinder 40 by welding, and then fixed to the soft silicone bracket 50 by screw connection.

[0123] The vibrators 1 are evenly distributed in an array of 2 rows and 3 columns on the soft silicone bracket 50. A dust cover 60 with a raised curved surface is provided above each vibrator 1. This design is suitable for waist or large area applications, and can provide a wider sound field and tactile feedback range.

[0124] When a human body is pressed against the vibrator array, the inner and outer connecting rib springs and the soft silicone bracket 50 are elastically deformed and tightly attached to the human body; the dust cover 60 provides support and reserves enough space for the vibrator 1 to vibrate.

[0125] When the vibrator 1 is working, the circular spring body performs reciprocating mechanical vibrations under the traction of the inner connecting rib 20 and the outer connecting rib 30, achieving the purpose of touch feedback. At the same time, the vibration is transmitted along the bones to the ear to realize auditory perception. In this configuration, the vibrators 1 are grouped in pairs, the leftmost group is the left surround, the rightmost group is the right surround, and the middle group is the low-frequency effect, achieving a full range of sound and tactile experience.

[0126] Example 8 2-row 2-column oscillator array + rectangular spring

[0127] Please refer to Fig. 9 This embodiment shows a 2-row 2-column vibrator array device, using a rectangular spring body. The rectangular spring body is connected and fixed to the vibrator outer cylinder 40 by welding, and then fixed to the soft silicone bracket 50 by screw connection.

[0128] The vibrators 1 are evenly distributed in an array of 2 rows and 2 columns on the soft silicone bracket 50. A flat dust cover 60 is provided above each vibrator 1. This design is suitable for back or chest applications and can provide a balanced sound field and tactile feedback.

[0129] When a human body is pressed against the vibrator array, the inner and outer connecting rib springs and the soft silicone bracket 50 are elastically deformed and tightly attached to the human body; the dust cover 60 provides support and reserves enough space for the vibrator 1 to vibrate.

[0130] When the vibrator 1 is working, the rectangular spring body performs reciprocating mechanical vibrations under the traction of the inner connecting rib 20 and the outer connecting rib 30, achieving the purpose of touch feedback. At the same time, the vibration is transmitted along the bones to the ear to achieve auditory perception. In this configuration, the vibrators 1 are grouped in pairs, the leftmost group is the left surround, and the rightmost group is the right surround, achieving a stereo effect.

[0131] Example 9: 2-row 2-column oscillator array + racetrack-shaped spring

[0132] Please refer to Fig.10 This embodiment shows another 2-row 2-column vibrator array device, but uses a racetrack-shaped spring sheet body. The racetrack-shaped spring sheet body is connected and fixed to the vibrator outer cylinder 40 by welding, and then fixed to the soft silicone bracket 50 by screw connection.

[0133] The vibrators 1 are evenly distributed on the soft silicone bracket 50 in an array of 2 rows and 2 columns. A flat dust cover 60 is set above each vibrator 1. This design combines the balance of a circle and the linear characteristics of a rectangle, and is suitable for applications that need to extend in a certain direction, such as back or leg devices.

[0134] When a human body is pressed against the vibrator array, the inner and outer connecting rib springs and the soft silicone bracket 50 are elastically deformed and tightly attached to the human body; the dust cover 60 provides support and reserves enough space for the vibrator 1 to vibrate.

[0135] When the vibrator 1 is working, the runway-shaped spring body performs reciprocating mechanical vibrations under the traction of the inner connecting rib 20 and the outer connecting rib 30, thereby achieving the purpose of touch feedback. At the same time, the vibration is transmitted along the bones to the ear to realize auditory perception. In this configuration, the vibrators 1 are grouped in pairs, the leftmost group is the left surround, and the rightmost group is the right surround, achieving a stereo effect.

[0136] These embodiments demonstrate the diversity and adaptability of the present invention, which can meet the needs of different application scenarios and provide flexible solutions for the fields of tactile feedback and bone conduction audio output.

[0137] Example 10

[0138] Please refer to Figure 11-12 The main carrier structure adopts a hexagonal or rectangular soft silicone bracket 50, and the six vibrators are arranged at the vertex positions of a regular hexagon. These vibrators can be controlled individually or synchronously. When controlled synchronously, the vibration experience of the massage will change from single-point vibration to hexagonal edge surface vibration formed by six vibrators 1, bringing a wider range of massage experience.

[0139] Further expanding this embodiment, another vibrator can be added at the center of the hexagonal array. Based on this feature, two hexagonal arrays can be integrated into a double hexagonal array as shown in the figure, in which two vibrators are shared by the two arrays. At the same time, the vibrator of one hexagonal array is located at the center of the other array, forming a staggered double hexagonal array structure. Similarly, the array can be further expanded through multiple staggered arrangements in different directions, showing extremely high scalability.

[0140] In terms of control algorithms, management is performed on a complete hexagonal array basis. Taking a double hexagonal array as an example, in the initial stage, the algorithm can be used to control the six vibrator sets A in the left hexagonal array. 左 Start vibrating. According to the changing needs, such as different massage scenes or parts, you can switch to the vibrator set A on the right edge of the array. 右 starts to vibrate, and the difference set A 左 -A 右 The vibrator that stops vibrating stops vibrating. Through this control process, the array can flexibly switch between different areas to form a continuously changing vibration effect. On a long array board composed of multiple hexagonal arrays arranged in a staggered manner, this vibration effect can gradually progress from left to right, forming a vibration feeling similar to a marquee. At the same time, the vibration effect can also be extended to other directions, bringing more complex vibration patterns.

[0141] Tactile feedback from left to right or other directions can be achieved not only through the vibration of multiple independent vibrators, but the design advantage of the hexagonal array is that it expands the original local area vibration to a larger area, making the vibration more obvious and intense. In addition, the design still retains the flexibility of algorithm control, which can realize complex functions of different positions and spatial perceptions, providing a more immersive experience.

[0142] It should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present invention should be included in the protection scope of the present invention.
