Description

Technical Field

[0001] The present invention belongs to the technical field of bone conduction, and in particular relates to an oscillator based on a double-sided spring sheet and Lorentz force and an application thereof. Background Art

[0002] Bone conduction technology is an innovative method of transmitting sound to the inner ear through vibration. Different from the traditional air conduction pathway (i.e., sound wave conduction outside the ear), it is mainly transmitted to the auditory nerve through human skin, subcutaneous tissue and bones, so that people can hear the sound. It has unique application advantages and safety. The sounds we hear in daily life are 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] When working, bone conduction speakers usually convert electroacoustic signals into mechanical vibrations first, and then transmit the vibrations to the inner ear area or tissue nerves through the human skin, subcutaneous tissue and bones. Specifically, bone conduction speakers usually include one or more vibration units (vibrators), and the vibrator's shrapnel and structural design are diverse, which can be used in the fields of tactile feedback, audio hearing, etc.

[0004] The vibrator is usually composed of a magnet, an intermediate block, a coil, and a spring. Each component plays an important role in the vibration system; in particular, the spring is used to adjust and control the vibration behavior of the vibrator.

[0005] At present, the designs of vibrators are mostly single-sided shrapnel, and the designs of double-sided shrapnel are rare; or the designs of double-sided shrapnel vibrators mostly use the same kind of shrapnel, and the designs of double-sided shrapnel using different kinds of shrapnel are rare; at the same time, the structure of the vibrator is not designed in full combination with the Lorentz force principle, and it is difficult to give full play to the performance of the vibrator.

[0006] Although the design of the single-sided shrapnel vibrator is simple, its performance is relatively limited. The single-sided shrapnel vibrator has only one active surface, which means that when it is working, only one side can participate in the vibration behavior, and the other side remains stationary and cannot participate in the vibration behavior. Although the design of the single-sided shrapnel has certain advantages in cost control and ease of production, the single-sided shrapnel cannot effectively meet the application scenario requirements for higher vibration frequencies or larger vibration amplitudes. In these cases, the efficiency and performance of the single-sided shrapnel will be greatly affected, thereby limiting its performance in high-demand application scenarios.

[0007] Since the design of the single-sided spring is an unbalanced design, its anti-drop and roller test effects are poor. For example, when falling, a vibrator with only a single-sided spring is equivalent to a carriage dropped from the air, but this carriage has only one wheel. When it falls to the ground, since only one side of the wheel touches the ground, the entire carriage continues to move. The huge impact force will cause the axle to tilt rapidly and violently, which can easily tilt the single-sided spring, causing the spring to deform, so that the mover will scrape against the side wall when vibrating, generating noise.

[0008] A significant disadvantage of single-sided springs is that their load-bearing capacity is usually limited. Since single-sided springs only provide elasticity and support on one side, their load-bearing capacity is often lower than that of double-sided springs. This means that in application scenarios that need to withstand large loads, single-sided springs may not be strong enough or stable enough.

[0009] Since the design of the single-sided spring is relatively simple, if one side of the spring is damaged or worn, it may cause the entire device to fail. In some critical applications, the failure of the single-sided spring may cause damage or failure of the entire product.

[0010] The design of a single-sided spring sheet may require high manufacturing precision to ensure that its elasticity and performance meet expectations. In the actual production process, the control of manufacturing precision may bring additional costs and process complexity.

[0011] The mechanical properties of single-sided springs are relatively simple. Their elastic behavior can usually only be achieved by adjusting the force in one direction, which means that in application scenarios that require complex mechanical properties (such as elastic response in different directions), single-sided springs may not provide sufficient solutions.

[0012] Single-sided springs may experience fatigue problems during long-term use. Since there is only one contact surface in its design that contacts the substrate, repeated elastic deformation may cause material fatigue and eventually lead to spring failure. This fatigue phenomenon is particularly evident under high-frequency and high-load conditions. Summary of the invention

[0013] The embodiment of the present invention provides an oscillator based on a double-sided spring sheet and Lorentz force and application thereof to solve the problems in the prior art.

[0014] The embodiment of the present invention adopts the following technical solution: a vibrator based on a double-sided spring sheet and Lorentz force, the vibrator comprising a stator assembly, a mover assembly, a first spring sheet, and a second spring sheet;

[0015] The stator assembly and the mover assembly are located between the first spring sheet and the second spring sheet; the mover assembly includes a magnet and a yoke, the stator assembly includes a coil, the mover assembly includes a coil, and the stator assembly includes a magnet and a yoke;

[0016] The coil is located in the magnetic field formed by the gap between the magnet and the yoke; when current passes through the coil, it will be affected by the Lorentz force generated by the magnetic field on the coil or conversely the reaction force generated by the coil on the magnet or the yoke, which serves as the driving force for the movement of the movable component.

[0017] The double-sided spring pieces may be the same spring pieces or different spring pieces, and may be spring pieces fixed at the center or spring pieces fixed at the periphery.

[0018] The double-sided spring vibrator can be a single-moving vibrator or a double-moving vibrator.

[0019] Furthermore, the single moving vibrator can be divided into a moving coil vibrator, a moving magnet vibrator and a moving iron vibrator; the double moving vibrator can be divided into an inner moving magnet and outer moving coil double moving type or an inner moving coil and outer moving magnet double moving type, an inner moving iron and outer moving coil magnet double moving type and an inner moving iron and outer moving magnet coil double moving vibrator.

[0020] Furthermore, the double-sided spring sheet includes a flat sheet body, which includes a central portion and a peripheral portion, and a plurality of discontinuous through holes or through grooves are provided on the flat sheet body, and the central portion and the peripheral portion are connected by at least three connecting rods or connecting ribs; the spring sheet is made of metal, and the central portion of the spring sheet includes a regular or irregular pattern; the connecting rods or connecting ribs are single-group rotationally symmetrical or multiple-group rotationally symmetrical; the connecting rods or connecting ribs are spiral or non-spiral; the peripheral portion is a closed ring or an discontinuous ring; the spiral or non-spiral connecting rods or connecting ribs extend from the central portion to the peripheral portion, and can be connected, suspended, or both; the spiral or non-spiral connecting rods or connecting ribs can be centrally fixed, peripherally fixed, or both; the spiral or non-spiral connecting rods or connecting ribs can be used as a hard support for the vibrator, or as an elastic support for the vibrator.

[0021] Furthermore, the spring pieces at both ends of the vibrator may both be fixed in the middle, or both be fixed in the periphery, or one end may be fixed in the middle and the other end may be fixed in the periphery; the magnetic lines of force of the vibrator pass from the north pole of the magnet through the middle of the coil via the conductive magnetic disk and return to the south pole of the magnet; the vibrator may be a single-moving vibrator or a double-moving vibrator; the vibrator may be a moving coil type or a moving magnet type; the vibrator may be a hybrid double-moving vibrator such as an inner moving magnet and an outer moving coil or an inner moving coil and an outer moving magnet.

[0022] Further, the double-moving vibrator includes a double-moving vibrator body, the double-moving vibrator body includes an outer tube, a first spring sheet, a second spring sheet, a first mover assembly and a second mover assembly, the first mover assembly includes a magnet combination structure and may also be a coil combination structure, the second mover assembly includes a coil combination structure and may also be a magnet combination structure, the first mover assembly is arranged in the outer tube, the second mover assembly is arranged in the outer tube and is located on the outside or inside of the first mover assembly, the first mover assembly is fixedly connected to the first spring sheet through at least one position, the second mover assembly is fixedly connected to the second spring sheet through at least one position, and the two mover assemblies and the outer tube are respectively connected to the connection points in the spring sheets;

[0023] Looking outward from the center, the permanent magnet is inside and the coil is outside, or the coil may be inside and the magnet is outside.

[0024] Furthermore, the double-sided spring clip includes a spring clip body, which includes a central portion, a peripheral portion, a connecting rod, and a central connecting point. The central portion is used to connect with the vibrator to fix the spring clip, and may be circular or polygonal; the peripheral portion is used to connect with the body of the device to fix the spring clip, forming a supporting portion of the spring clip; the connecting rod is used to connect the peripheral portion and the central portion. When the moving parts of the bone conduction vibrator and the actuator move, the rod provides symmetrical elastic support, so that the moving parts remain balanced and stable when vibrating in the Z-axis direction.

[0025] The application of the oscillator based on double-sided shrapnel and Lorentz force is suitable for bone conduction headphones, bone conduction glasses, wired headphones, wireless headphones, AR glasses, VR glasses, smart watches, smart bracelets, head-mounted devices, wearable devices, smart phones, game controllers, game headphones, game steering wheels, game pedals, mice, keyboards, touch screens, electrical control panels, touch devices, screen sound devices, vehicle-mounted tactile feedback devices, smart cockpits, game chairs, massage chairs, massagers, tactile feedback vests, tactile feedback gloves, tactile feedback belts, tactile feedback leg devices, auxiliary hearing aids, sleep aids or tactile feedback network interconnection devices.

[0026] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0027] 1. The design of double-sided spring clip is a balanced design, and its anti-drop and roller test effects will be much better. When falling, the spring clips on both sides will fall to the ground at the same time, and the huge impact force of the mover will be borne by the spring clips on both sides in a relatively balanced manner, thus avoiding the risk of deformation of the spring clip caused by the easy tilting of one side.

[0028] 2. For the vibrator of double-sided spring clips, when the spring clips on both sides are set to symmetrical connecting ribs, for example, the spring clip on one side is designed to rotate clockwise, and the connecting ribs of the spring clip on the other side are designed to rotate counterclockwise, when the mover vibrates along the Z-axis, the circumferential motions generated by the connecting ribs of the spring clips on both sides just cancel each other out, thereby making the movement of the mover along the Z-axis more uniform.

[0029] 3. The symmetrical design of the double-sided spring vibrator makes positioning and assembly easier during production and assembly.

[0030] 4. A significant advantage of the double-sided shrapnel vibrator is the improvement of vibration efficiency and vibration performance. During the vibration process of the traditional single-shrapnel vibrator, the energy transfer and conversion are limited by the single-sided shrapnel, resulting in low energy conversion efficiency. The double-shrapnel design achieves higher energy transfer efficiency through the mechanical vibration behavior of the two shrapnel. Both shrapnels can receive and release vibration energy, so that the vibration system can operate stably at higher frequencies and vibration intensities, improving the overall vibration effect.

[0031] 5. In the design of traditional single-shrapnel vibrator, the force on the shrapnel often leads to local stress concentration, affecting its long-term reliability and durability. The double-sided shrapnel vibrator design reduces the stress concentration on the single-sided shrapnel by evenly distributing the vibration load on both sides, thereby improving the fatigue resistance and durability of the vibrator. This uniform load distribution can effectively extend the service life of the vibrator and maintain stable performance during long-term operation.

[0032] 6. Double-sided springs use high-performance metal materials, such as stainless steel, beryllium copper, titanium alloy, etc. These materials 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 can work in a wider range of temperature and stress, and is suitable for more complex and special application scenarios;

[0033] 7. The double-sided spring vibrator adopts more flexible connection methods, such as bonding, welding, screw connection, snap connection, etc. These connection methods can fully meet the connection requirements between the spring and the vibrator's various structural parts. At the same time, it also provides convenience for subsequent maintenance and replacement.

[0034] 8. The newly designed double-sided shrapnel vibrator has higher versatility and practicality in structure and function. Compared with the vibrator with single-sided shrapnel, the double-sided shrapnel vibrator can play a better role in consumer electronic products such as bone conduction headphones, hearing aids, massagers, virtual reality, medical equipment, etc. The improvement of versatility and adaptability makes the newly designed shrapnel more competitive and has a better application prospect in the market.

[0035] In summary, the vibrator designed based on the double-sided spring and Lorentz force principle shows unique advantages and value in terms of efficient energy transfer, mechanical vibration performance, durability, material properties, flexible connection methods and adaptability. It can also better match the higher application requirements of related products in terms of tactile feedback and audio hearing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0067] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0068] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0069] Reference Figures 1 to 27 As shown, an embodiment of the present invention provides a vibrator based on a double-sided spring sheet and Lorentz force,

[0070] The vibrator is composed of a stator assembly, a mover assembly, a spring piece 14, and a spring piece 2 15;

[0071] The stator assembly and the mover assembly are located between the spring piece 14 and the spring piece 2 15; the mover assembly includes a magnet 2 and an intermediate block 4, the stator assembly includes a coil 3, the mover assembly includes a coil 3, and the stator assembly includes a magnet 2 and an intermediate block 4;

[0072] The coil 3 is located in the magnetic field formed by the gap between the magnet 2 and the intermediate block 4. When current passes through the coil 3, the coil 3 is subjected to the Lorentz force generated by the magnetic field on the coil 3 or the reaction force generated by the coil 3 on the magnet 2 or the intermediate block 4, which serves as the driving force for the movement of the mover assembly.

[0073] The double-sided spring pieces may be the same spring pieces or different spring pieces, and may be spring pieces with a central support or spring pieces with a peripheral support;

[0074] The double-sided spring vibrator can be a single-moving vibrator or a double-moving vibrator.

[0075] It should be noted that the spring is made of metal, preferably stainless steel, beryllium copper and titanium alloy;

[0076] The center of the spring piece includes regular or irregular shapes such as circle, rectangle, oval, etc.

[0077] The newly designed vibrator adopts double-sided springs, which is an unbalanced design. Combined with the Lorentz force principle, by controlling the magnetic field and current, the double-sided springs achieve precise and efficient mechanical vibration under the uniform action of the Lorentz force.

[0078] The double-sided spring clips may be a combination of spring clips with central support, a combination of spring clips with peripheral support, or a combination of spring clips with one side centrally supported and one side peripherally supported.

[0079] The flat body of the double-sided spring is made of metal materials, such as stainless steel, beryllium copper, titanium alloy, etc., 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 spring.

[0080] The main body of the shrapnel is connected to the outer cylinder of the vibrator by hard contact and tight fit, such as welding, screw connection, riveting, etc., to meet the connection requirements of the vibrator under high and low frequency vibration conditions. The cross-sectional shape and position of the connecting ribs are rotationally symmetrical to ensure that the external stress can be effectively dispersed and borne during the deformation of the shrapnel, protecting the main body from damage by transitional stress, and avoiding interference with the internal connecting ribs.

[0081] Various openings or slots with various cross-sectional shapes and sizes are used near the shrapnel connection ribs to adapt to the stress distribution of the shrapnel under different vibration states and meet the connection requirements of the shrapnel with the vibrator outer cylinder and other devices. The gaps at the shrapnel connection ribs are also distributed in rotational symmetry to ensure that the profit received by the shrapnel during vibration can be evenly distributed to avoid excessive local stress.

[0082] The design of the double-sided spring clip also includes multiple positioning holes or positioning grooves, which can well ensure that the spring clip is accurately and stably connected and fastened to a specific entity or component (such as a guide disk, a positioning pin, etc.). At the same time, the design of the positioning holes or positioning grooves also solves the convenience of installation and disassembly, and facilitates subsequent maintenance and replacement work.

[0083] In short, the newly designed vibrator based on the Lorentz force principle and double-sided springs has been optimized and innovated in terms of materials, structure, connection methods, etc. to meet the requirements of more complex or special application scenarios. The newly designed vibrator not only effectively improves the performance of the vibrator, but also effectively improves its practicality and versatility;

[0084] The design of the vibrator is based on the Lorentz force principle and conforms to the Lorentz force principle. It is composed of components such as magnets, intermediate blocks, coils and double-sided springs. Assuming that on the radial cross section of the vibrator, the connection point between the outer cylinder and the spring is O, and the connection points between the mover assembly 1 and the mover assembly 2 and the spring are A and B respectively. Because the forces between the two mover assemblies are in opposite directions and have the same amplitude. Therefore, the forces acting on the springs are generally opposite in direction and close in amplitude (assuming that the accelerations of the mover assembly 1 and the mover assembly 2 are zero, or close in acceleration). So, the question now is the relationship between the force pair A / B and the force of O, and there are the following three possibilities:

[0085] On the connecting branch, the connection point O is located between the connection points A and B. We call the relationship between the opposing force pair at points A / B and the force at point O a scissor-type force relationship. It is similar to when you cut something, the forces on the two forks of the scissors are in opposite directions with the same or similar amplitudes, which is similar to the force pair at points A / B here. The hinge in the middle of the scissors is similar to point O.

[0086] On the connecting branch, the connecting point O is on the extension line of the connecting points A and B. That is, A is between B and O, or B is between A and O. We call the relationship between the opposing forces at points A / B and the force at point O a lever-type force relationship diagram, as shown in Fig. 27 As shown;

[0087] The design problem of the shrapnel actually becomes the following problem: Assuming that the force pair A / B is known, how to design the shrapnel so that the force pair at point A / B produces the maximum force on point O. This is the vibration transmission effect of the shrapnel, which converts the force pair A / B into the force on the outer tube at O, and the force of the outer tube then acts on the headphone head surface structure, and the headphone head surface structure then acts on the hard bone or cartilage of the human head.

[0088] The following method:

[0089] Method 1 (magnetic coil parallel type): inner mover assembly 1: magnet assembly; outer mover assembly 2: coil assembly;

In addition, the central part 26 has three connecting ribs connected; the connecting rods and connecting ribs are evenly distributed in the spring piece flat plate body 17 in a 120° rotational symmetric manner; wherein, the central part 26 is designed with a central positioning hole 25, which provides positioning and centering conditions for the introduction of the positioning pin 32 and the centering of other components; the connecting ribs and the spring piece peripheral part 30 are designed with a card slot 1 21 and a card slot 2 22, which provide positioning and connection conditions for the spring piece to be connected and fixed with the inner tube 12 and the outer tube 13 by snap connection, riveting, welding, etc. A sufficient space 23 is designed between the connecting ribs and the connecting rods to prevent the connecting ribs and the connecting rods from interfering with each other when the vibrator vibrates.

[0094] Example 2- Figure 2 : Central fixed spring piece 1;

[0095] The fan-shaped spring piece shown in the figure is a peripheral fixed spring piece 16, and the peripheral part 30 extends to the central part 26 with four connecting ribs connected; the connecting ribs are evenly distributed in the spring piece flat sheet body 17 in a 90° rotationally symmetrical manner; wherein the central part 26 is designed with a central positioning hole 25 to provide positioning and centering conditions for the introduction of the positioning pin 32 and the centering of other components; the peripheral part 30 of the spring piece flat sheet body 17 is designed with a card slot 20 to provide positioning and connection conditions for the spring piece and the outer tube 13 to be connected and fixed by snap connection, riveting, welding, etc. A sufficient space 23 is designed between the connecting ribs to prevent the connecting ribs from interfering with each other when the vibrator vibrates.

[0101] The vibrator shown in the figure is composed of a double-sided central fixed spring sheet 1, a magnet 2, a coil 3, an intermediate block 4, a magnetic disk 7, a magnetic ring 10, an inner cylinder 12 and an outer cylinder 13. The magnetic ring 10 is bent, and the coil 3 is placed at the inner bending of the magnetic ring 10 and connected and fixed to the outer cylinder 13; the intermediate block 4 is connected and fixed to the outer cylinder 13 on the other side of the magnetic ring 10, and the three together with the outer cylinder 13 constitute the stator part of the vibrator; the magnet 2, the magnetic disk 1 8 and the magnetic disk 2 9 are mutually connected and fixed on the inner cylinder 12 of the vibrator, constituting the movable part of the vibrator.

[0102] Based on the Lorentz force principle, the magnetic lines of force start from the north pole of the magnet 2, pass through the middle of the coil 3 via the magnetic disk 7 and return to the south pole of the magnet 2; when the magnetic lines of force pass through the coil 3, the current in the coil 3 cuts the magnetic lines of force to generate the Lorentz force, and the stator part of the vibrator, namely the outer cylinder 13, the magnetic ring 10, the middle block 4 and the coil 3 are fixed; the mover part of the vibrator, namely the inner cylinder 12, the magnetic disk 7 and the magnet 2, performs reciprocating mechanical vibrations under the action of the Lorentz force and the traction of the double-sided center-fixed spring 1, and the vibration is transmitted to the human skin, subcutaneous tissue and bones and transmitted to the inner ear area or tissue nerves, thereby realizing tactile feedback and audio hearing.

The coil 3 and the magnetic guide ring 10 are connected and fixed on the outer cylinder 13 to form the stator part of the vibrator; the magnet 2, the first magnetic guide disk 8 and the second magnetic guide disk 9 are connected and fixed on the inner cylinder 12 to form the mover part of the vibrator.
