Description

Technical Field

[0001] This invention relates to the field of oscillator technology, specifically to a parallel push-pull nonlinear cancelling moving iron and moving coil magnetic double-moving oscillator and its applications. Background Technology

[0002] The vibrator and / or haptic feedback actuator design of bone conduction headphones, particularly the dynamic coil design, offers several advantages. For example, dynamic coils are commonly used in conventional speakers, making the technology relatively mature. Furthermore, the low motion mass of the vibrator results in a faster response to signal changes and lower latency. Additionally, the low motion mass allows for a higher bandwidth.

[0003] Existing moving-coil oscillator and actuator designs often exhibit high nonlinearity due to inherent limitations in the magnet and coil combination design. This means the force or acceleration applied to the moving coil component results in significant distortion at low or high frequencies, known as total harmonic distortion (THD). Please refer to the appendix. Figure 28 The figure shows the distortion curve of a currently designed moving-coil oscillator. It can be seen that the distortion reaches 55% near 35Hz and 65% around 5kHz-6kHz. Such high distortion indicates that in the low-frequency range, the distortion of the audio signal or haptic feedback signal leads to a significant discrepancy between the perceived sound quality and the actual haptic feedback. Generally, a distortion greater than 10% is unacceptable according to audio standards.

[0004] Furthermore, for oscillators with a single moving iron, a single moving magnet, or a single moving coil, since there is only one oscillator system, the system has only one resonant frequency. Please refer to the appendix. Figure 26 When the input signal to the oscillator approaches the resonant frequency, the frequency response amplitude of the oscillator will produce a spike. When the input signal moves away from the resonant frequency, the amplitude of the frequency response curve of the oscillator will decay rapidly. Thus, for wideband input signals, the bandwidth of the oscillator's frequency response curve is relatively narrow. Summary of the Invention

[0005] One of the objectives of this invention is to provide a parallel push-pull type nonlinear canceling moving iron and moving coil magnetic double oscillator.

[0006] Another objective of this invention is to provide an application of a parallel push-pull type nonlinear canceling moving iron and moving coil magnetic double oscillator.

[0007] The technical solution of this invention is: a parallel push-pull nonlinear cancelling moving iron and moving coil magnetic dual-moving oscillator, comprising an oscillator body, the oscillator body comprising an outer cylinder, a first and a second transmission plate, a first moving element assembly and a second moving element assembly, the first moving element assembly comprising an iron core assembly structure, and the second moving element assembly comprising a coil and magnet assembly structure, the first moving element assembly being disposed inside the outer cylinder, and the second moving element assembly being disposed inside the outer cylinder and located outside the first moving element assembly, the first moving element assembly being fixedly connected to the first transmission plate through at least one point, and the second moving element assembly being fixedly connected to the second transmission plate through at least one point; viewed from the center outward, the coil in the coil and magnet assembly structure is inside, and the permanent magnet is outside; the first moving element assembly and the second moving element assembly are simultaneously subjected to paired pushing and pulling electromagnetic forces, exhibiting a push-pull structural feature.

[0008] This invention provides an improved, parallel push-pull type nonlinear cancelling moving iron and moving coil magnetic double oscillator, which, compared with the prior art, has the following improvements and advantages:

[0009] 1. This invention proposes a hybrid dual-moving oscillator design with a parallel push-pull configuration of a moving iron and a moving magnetic coil. The basic idea of ​​the push-pull design is to generate a pair of opposing forces for each moving element component, one being a tension force and the other a push force, forming a push-pull force structure. Only with a push-pull force structure can the nonlinear terms in the total force be partially or completely canceled out.

[0010] 2. This invention proposes a hybrid dual-moving oscillator design with parallel iron and moving magnetic coils, which can partially or completely cancel out the nonlinear terms of the driving force or acceleration of the moving coil component and the coil current through a symmetrical or asymmetrical design. This greatly reduces the distortion of the oscillator and improves the fidelity of the oscillator for the original audio signal or tactile feedback signal.

[0011] 3. The nonlinear term cancellation of the hybrid oscillator of the present invention reduces the total harmonic distortion (THD) in the low-frequency range from the original peak value of 55% to below 15% and the THD in the high-frequency range from the original peak value of 65% to below 5%. The reduction in the distortion curve is equivalent to a reduction in the resonant frequency of the oscillator system, thereby improving the sound quality in the low and mid-frequency ranges. In addition, it can also be equivalent to an increase in the sensitivity of the oscillator system and a reduction in power consumption.

[0012] 4. This invention reveals the relationship between the spring constants k2 and k3 and the target resonant frequency ω. r1 and ω r2And the relationship between m1, m2 and m3, using the target resonant frequency, to design the stiffness coefficient of the transmission plate in reverse, that is, assuming the resonant frequency ω. r1 and ω r2 By modifying the material and thickness of the vibration transducer, as well as the length and width of the vibration transmission limbs, the final stiffness coefficient values ​​can be made close to the calculated k2 and k3.

[0013] 5. The hybrid dual-moving oscillator design method of the present invention, which combines moving iron and moving magnetic coil, results in a oscillator with uniform and balanced force, realizing the overall translational vibration of the oscillator and achieving the best vibration effect.

[0041] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] For the design of canceling nonlinear terms, there are 2N magnetic domains inside the oscillator. The magnetic domains are paired and defined as magnetic domain D. 1,i and D 2,i Where i = 1, 2, 3, ..., N. The closed curves of the main magnetic field lines of the coil and the main magnetic field lines of the permanent magnet respectively pass through the magnetic field domain D. 1,i and D 2,i And in the magnetic domain D 1,i In the coil, the direction of the magnetic field lines is the same as that of the permanent magnet, while in the magnetic domain D... 2,i In the coil, the direction of the magnetic field lines is opposite to that of the permanent magnet. Or in the magnetic domain D... 1,i In the coil, the direction of the magnetic field lines is opposite to that of the permanent magnet, while in the magnetic domain D... 2,i In this case, the direction of the magnetic field lines of the coil is the same as the direction of the magnetic field lines of the permanent magnet.

[0043] When the magnetic field lines of a coil passing through a magnetic field are in the same direction as the magnetic field lines of a permanent magnet, the total magnetic flux is equal to the sum of the magnetic flux produced by the coil and the magnetic flux produced by the permanent magnet. When the magnetic field lines of a coil passing through a magnetic field are in the same direction as the magnetic field lines of a permanent magnet, the total magnetic flux is equal to the difference between the magnetic flux produced by the coil and the magnetic flux produced by the permanent magnet.

[0044] Magnetic domain: A magnetic domain is a spatial region filled with electromagnetic energy, generally composed of air or a medium with low permeability (e.g., relative permeability <1000), including the region where the magnetic material is located; the moving coil oscillator of this invention, which cancels out nonlinear terms, includes at least one magnetic domain. A magnetic domain refers to a spatial region where a certain electromagnetic field or multiple electromagnetic fields exist, causing interaction forces between the components surrounding the magnetic domain. We define such a region as a magnetic domain, or simply a magnetic domain. A magnetic domain is the spatial region where magnetic interaction occurs. It is generally composed of the spatial region between permanent magnets (producing attractive or repulsive interactions), or the spatial region enclosed by permanent magnets and magnetic conductors (producing attractive interactions), or the spatial region enclosed by magnetic conductors (yokes) magnetized by permanent magnets, or a group of spatial regions where magnetic interaction occurs within permanent magnets (the permeability of the hard magnetic material constituting the permanent magnet is close to that of air).

[0045] Several types of magnetic domains:

[0046] 1) The space between the permanent magnets is filled with a medium (air, with a relative permeability slightly greater than 1).

[0047] The medium above can be replaced with a paramagnetic material, an antimagnetic material, or a ferromagnetic material with a relative permeability of less than 1000. For example:

[0048] a. Paramagnetic materials: These have a relative permeability slightly greater than 1. Examples of paramagnetic materials include air, oxygen, tin, aluminum, and lead. When a paramagnetic material is placed in a magnetic field, the magnetic induction intensity B increases slightly.

[0049] b. Diamagnetic materials: These are materials with a relative permeability slightly less than 1, such as hydrogen, copper, graphite, silver, and zinc. They are also called diamagnetic materials. When a diamagnetic material is placed in a magnetic field, the magnetic induction intensity B decreases slightly.

[0050] c. Ferromagnetic materials: These have a relative permeability much greater than 1 but less than 1000. Examples include iron, steel, cast iron, nickel, and cobalt. Materials with a relative permeability less than 1000 include cobalt, unannealed cast iron, and annealed cast iron. Magnetic fluids, on the other hand, have a relative permeability below 10.

[0051] like Figure 59 As shown, permanent magnet 1 and permanent magnet 2 are surrounded by air. The permanent magnets attract each other.

[0052] Magnetic domain D1: The spatial region enclosed by the air medium between permanent magnet 1 and permanent magnet 2.

[0053] Magnetic domain D2: The spatial region enclosed by the partial permanent magnet 2 and the air medium surrounding the partial permanent magnet 2.

[0054] Magnetic domain D3: The spatial region enclosed by all permanent magnets 1 and the air medium surrounding permanent magnets 1.

[0055] Magnetic domain D4: The spatial region enclosed by all permanent magnets 1 and 2, and the air medium surrounding permanent magnets 1 and 2.

[0056] Magnetic domain D5: The spatial region enclosed by air medium on the side of permanent magnet 2 away from permanent magnet 1.

[0057] Magnetic domain D6: The spatial region enclosed by the permanent magnet material medium surrounding part of the permanent magnet 1.

[0058] like Figure 60 As shown, permanent magnet 1 and permanent magnet 2 are surrounded by air. The permanent magnets attract each other. Similarly, D1-D6 can be defined.

[0059] 2) The space between the permanent magnet and the magnetic conductor is filled with a medium (air, with a relative permeability close to 1).

[0060] 3) such as Figures 61-62 As shown, the space between the magnetic conductors is filled with a medium (air, with a relative permeability close to 1).

[0061] Magnetic domain D1: The spatial region enclosed by the air medium between magnetic conductor 1 and magnetic conductor 2.

[0062] Magnetic domain D2: The spatial region enclosed by a portion of permanent magnets and a portion of magnetic conductors 2, as well as the surrounding air medium.

[0063] Magnetic domain D3: The spatial region enclosed by all the magnetic conductors 1, some permanent magnets, and the air medium surrounding the magnetic conductors 1.

[0064] Magnetic domain D4: The spatial region enclosed by all magnetic conductors 1 and 2, permanent magnets, and the air medium surrounding them.

[0065] Magnetic domain D5: The spatial region enclosed by the air medium on the side of conductor 2 away from magnetic conductor 1.

[0066] Magnetic domain D6: The spatial region enclosed by a permanent magnetic material medium surrounding a portion of the permanent magnet.

[0067] 4) such as Figure 63 As shown, the space between the magnet and the magnetic conductor is filled with a medium (magnetorheological fluid, with a relative permeability between 5 and 9).

[0068] 5) The internal space of the permanent magnet is filled with a medium (permanent magnet material, relative permeability <1000).

[0069] like Figure 64 As shown in the previous example, magnetic domain D6 has a permanent magnet material as its medium, such as sintered ferrite, samarium cobalt and neodymium iron boron with a permeability of about 1.05, bonded ferrite also has a permeability of about 1.05, and bonded neodymium magnets have a permeability range of about 1.1 to 1.7.

[0070] There are two types of magnetic force domains. The first type is the magnetic force domain enclosed within the mover assembly or the stator assembly. The second type is the magnetic force domain enclosed between the mover assembly and the stator assembly. We are more interested in the second type of magnetic force domain. Therefore, by analyzing the second type of magnetic force domain, we can obtain the force analysis of the mover assembly, thereby obtaining the resultant force of the mover assembly in the oscillator system, and further derive its vibration equation.

[0071] Example 1

[0072] Please refer to Figure 1-8 ,as well as Figure 24-26A nonlinear cancelling moving iron and moving coil magnetic parallel push-pull type double-moving oscillator includes an oscillator body 11, which includes a first transmission plate 1 and a second transmission plate 2, a first mover assembly 3 and a second mover assembly 4. The first mover assembly 3 includes an iron core 31 combination structure, and the second mover assembly 4 includes a coil magnet combination structure. The first mover assembly 3 is disposed inside an outer cylinder 5, and the second mover assembly 4 is disposed inside the outer cylinder 5 and located outside the first mover assembly 3. The first mover assembly 3 is fixedly connected to the first transmission plate 1 through at least one point, and the second mover assembly 4 is fixedly connected to the second transmission plate 2 through at least one point. The first mover assembly 3 and the second mover assembly 4 are simultaneously subjected to paired pushing and pulling electromagnetic forces, exhibiting a push-pull structural feature.

[0073] The first vibration transducer 1 is a first double-spring vibration transducer device, which includes a first vertical portion 1a and a first bent portion 1b of a spring extending inclined towards the inner wall of the outer cylinder 5 along the outer periphery of the plane containing the first vertical portion 1a; the second vibration transducer 2 is a first double-spring vibration transducer device, which includes a second vertical portion 2a and a second bent portion 2b of a spring extending inclined towards the inner wall of the outer cylinder 5 along the outer periphery of the plane containing the second vertical portion 2a; the core 31 assembly structure includes a core 31 and a first magnetic conductor. The coil magnet assembly structure includes a permanent magnet, a coil, and a second magnetically conductive body or a second non-magnetically conductive body 41. Viewed from the center outwards, the coil C1 is inside, and the permanent magnet is outside. There are two permanent magnets, M1 and M2, with the polarities of opposite end faces of adjacent permanent magnets M1 and M2 being the same. There is one coil. The first double-spring vibration transducer device is fixed to the top surface of the outer cylinder 5, and the second double-spring vibration transducer device is fixed to the bottom surface of the outer cylinder 5. Both ends of the iron core 31 are respectively fixed to the first double-spring... On the first vertical part 1a of the vibration transducer device and the second vertical part 2a of the second double-spring vibration transducer device, the first magnetic material or the first non-magnetic material 32 is fixed on the iron core 31. An inner cylinder 6 is provided inside the outer cylinder 5. The second magnetic material or the second non-magnetic material 41 is fixed in the middle of the inner wall of the inner cylinder 6. Two permanent magnets M1 and M2 are respectively fixed on both sides of the second magnetic material or the second non-magnetic material 41. The coil C1 is fixed on the second magnetic material or the second non-magnetic material 41. The outer side of the two permanent magnets M1 and M2... The second magnetic ring 42 is fixedly mounted on the side. The two second magnetic rings 42 are respectively on the first bending part 1b of the first double spring transducer device and the second bending part 2b of the second double spring transducer device. The first moving part assembly 3 and the second moving part assembly 4 are arranged in an alternating concave-convex interlocking shape. The closed curve of the main magnetic field line of the coil C1 and the closed curve of the main magnetic field line of the permanent magnets M1 and M2 alternately pass through the first moving part assembly 3 and the second moving part assembly 4. There are 4 sets of magnetic domains inside the oscillator body 11. The magnetic domains are combined in pairs and are defined as magnetic domain D. 1,1 D 2,1 D 1,2 D 2,2 The closed curves of the main magnetic field lines of coil C1 and the closed curves of the main magnetic field lines of permanent magnets M1 and M2 respectively pass through the magnetic field domain D. 1,1 D 2,1 D 1,2 D 2,2 And in the magnetic domain D 1,1 In the magnetic field, the direction of the magnetic field lines of coil C1 is the same as that of permanent magnets M1 and M2, while in the magnetic domain D... 2,1In this configuration, the direction of the magnetic field lines of the coil C1 is opposite to the direction of the magnetic field lines of the permanent magnets M1 and M2.

[0074] The outer cylinder 5 can be a magnetic outer cylinder 5 or a non-magnetic outer cylinder 5. In order to reduce magnetic resistance, a magnetic outer cylinder 5 is preferred. The cross-section of the outer cylinder 5 can be circular, square, or irregular, and can be continuous or discontinuous, such as columnar connection or grid discontinuity.

[0075] To further explain the nonlinear term cancellation of the moving iron and moving coil magnetic hybrid oscillator, please refer to the appendix. Figure 4 The four annular air gaps, marked with dense dots along the axial direction in the diagram, are the spatial regions enclosed by the first mover assembly 3 and the second mover assembly 4. Within these regions, the magnetic field lines formed by coil C1 and the permanent magnets M1 and M2 pass through. On both sides of these annular air gaps along the Z-axis are yokes of different shapes. According to the principles of electromagnetism, the yokes on both sides of these air gaps through which the magnetic field lines pass will generate mutually attractive electromagnetic forces; therefore, the regions where these magnetic forces act are called the magnetic field domains.

[0076] Please refer to the appendix. Figure 2 The diagram shows four air gaps forming magnetic action domains D. 1,1 D 2,1 D 1,2 D 2,2 Within the magnetic field domain, the total magnetic flux / magnetic induction intensity generated by the superposition of the magnetic fields produced by permanent magnets M1 and M2 and the electromagnet C1 causes interaction forces to be generated among the components surrounding the magnetic field domain. The magnetic field domain D above... 1,1 D 2,1 D 1,2 D 2,2 Both are composed of stator and mover components. Therefore, in these magnetic domains, there will be interactive component forces between the first mover component 3 and the second mover component 4.

[0077] If multiple permanent magnets are arranged symmetrically, the symmetrical permanent magnets have the same size and magnetic force parameters.

[0078] If multiple coils are arranged symmetrically, the symmetrical coils have the same size and current value.

[0079] The current through coil C1 is i, and the corresponding magnetic flux is Φ. i The magnetic fluxes corresponding to permanent magnets M1 and M2 are Φ and Φ, respectively. M1 and Φ M2 .

[0080] Magnetic domain D 1,1 D 2,1 D 1,2 D2,2 Magnetic fields can be paired in pairs according to the symmetry case for D j =(D 1,j D 2,j ), j = 1, 2; including magnetic field pairs D1 = (D 1,1 D 2,1 ), and magnetic field pair D2=(D 1,2 D 2,2 ).

[0081] 1) Magnetic domain to D j =(D 1,j D 2,j When j=1, that is, the magnetic field pair D1=(D 1,1 D 2,1 ) magnetic flux

[0082] In magnetic domain D 1,1 In the magnetic field, the direction of the magnetic field lines corresponding to coil C1 is opposite to the direction of the magnetic field lines corresponding to permanent magnets M1 and M2. Therefore, in the magnetic field domain D... 1,1 In the middle, the total magnetic flux is Φ i1 and Φ M1 =Φ m The difference. In the magnetic domain D 2,1 In the magnetic field, the direction of the magnetic field lines corresponding to coil C1 is the same as the direction of the magnetic field lines corresponding to permanent magnets M1 and M2. Therefore, in the magnetic field domain D... 2,1 In the middle, the total magnetic flux is Φ i2 and Φ M1 =Φ m The added value.

[0083] Assume the magnetic flux corresponding to coil C1 is Φ i And the magnetic flux of magnets M1 and M2 is also the same, i.e., Φ M1 =Φ M2 =Φ m Furthermore, assuming that the magnetic field lines of magnet M1 are in the positive direction and the magnetic flux is also positive, then we have:

[0084] Φ D1,1 =Φ M1 -Φ i =Φ m -Φ i

[0085] Φ D2,1 =-Φ M2 -Φ i =-(Φ m +Φ i )

[0086] 2) Magnetic domain to D j =(D 1,j D 2,j When i = 2, that is, the magnetic field pair (D)1,2 D 2,2 ) magnetic flux

[0087] In magnetic domain D 1,2 In the middle, only the magnetic field lines corresponding to magnet M1 pass through, therefore the total magnetic flux is only Φ. M1 =Φ m In the magnetic domain D 2,2 In the equation, only the magnetic field lines corresponding to magnet M2 pass through, therefore the total magnetic flux is only Φ. M2 =Φ m .

[0088] Assume that the magnetic reluctance of the magnetic circuit formed by the electromagnetic field generated by the current i in coil C1 is Z. i Let N be the number of turns in coil C1, and i be the current intensity. Then we have:

[0089]

[0090] Assume the permeability of the magnetic circuit formed by the electromagnetic field generated by the current is G. i Then we have:

[0091]

[0092] The magnetic flux corresponding to permanent magnets M1 and M2 can also be expressed using the formula for magnetic induction intensity. Assume that the magnetic induction intensity at the magnetic end faces of permanent magnets M1 and M2 is both B. m The area of ​​each magnetic pole end is S m It can be obtained that...

[0093] Therefore,

[0094]

[0095]

[0096] Please refer to the appendix. Figure 3 Draw the closed magnetic field lines of coil C1, and the closed magnetic field lines of magnets M1 and M2. In the diagram, the closed magnetic field lines generated by coil C1 pass through the magnetic gap D. 1,1 D 2,1 The closed magnetic field lines generated by magnet M1 pass through the magnetic gap D in sequence. 1,1 D 1,2 The closed magnetic field lines generated by magnet M2 pass through the magnetic gap D in sequence. 2,1 D 2,2 .

[0097] Appendix Figure 5This is a schematic diagram of the oscillator subsystem composed of the first moving element assembly 3, the first transmission plate 1, and the spring plate 1 in the second transmission plate 2. Simultaneously, the first moving element assembly 3 and the magnetic domain D... 1,1 D 2,1 D 1,2 D 2,2 The positional relationships and the force analysis of the first moving part 3 are also illustrated. In the magnetic domain D... 1,1 The first moving part 3 is subjected to a rightward suction force F from the second moving part 4. 1,1 In the magnetic domain D 2,1 The first moving part 3 is subjected to a leftward suction force F from the second moving part 4. 2,1 In the magnetic domain D 1,2 The first moving part 3 is subjected to a leftward suction force F from the second moving part 4. 1,2 In the magnetic domain D 2,2 The first moving part 3 is subjected to a rightward suction force F from the second moving part 4. 2,2 .

[0098] Assuming magnetic field pair D j =(D 1,j D 2,j The resultant force corresponding to this is F. j (The positive and negative signs indicate different directions of the force). Taking the rightward direction as positive, the resultant force of the second mover assembly 4 on the first mover assembly 3 is:

[0099] F 第一动子组件 =F1+F2=F 1,1 -F 2,1 -F 1,2 +F 2,2

[0100] F 第一动子组件 =F1+F2=(F 1,1 -F 2,1 )+(-F 1,2 +F 2,2 )

[0101] Where F j It corresponds to the magnetic field pair D j =(D 1,j D 2,j The resultant force of ). As can be seen from the diagram above, for each magnetic domain, the force on D j =(D 1,j D 2,j The two forces acting on the moving component, F 1,j and F 2,j It has the following characteristics:

[0102] 1)F 1,j and F 2,jThe direction of the force is along the Z-axis, which is the direction of vibration.

[0103] 2)F 1,j and F 2,j As vectors, forces have opposite directions. F 1,j When the direction of the force is positive (for example, if we define the right side as positive), F 2,j The direction of the force is exactly negative. The converse is also true, i.e., F... 1,j When the direction of the force is negative, F 2,j The direction of the force is exactly positive.

[0104] 3)F 1,j and F 2,j The characteristic of forces occurring in pairs and with related directions means that the moving component being acted upon is simultaneously subjected to a thrust and a pull. This type of force distribution is called a push-pull force structure, and the corresponding design is called a push-pull design.

[0105] 4)F 1,j and F 2,j Appearing in pairs, each F 1,j and F 2,j The resultant force ∑F formed by each 1,j and ∑F 2,j Between them, there must be a pushing force and a pulling force, with the resultant force ∑F 1,j and ∑F 2,j It is also a push-pull type of force-bearing structure.

[0106] Appendix Figure 6 This is a schematic diagram of the oscillator subsystem composed of the second mover assembly 4, the first transmission plate 1, and the spring plates in the second transmission plate 2. Simultaneously, the second mover assembly 4 and the magnetic domain D... 1,1 D 2,1 D 1,2 D 2,2 The positional relationships and the force analysis of the second moving part 4 are also illustrated. In the magnetic domain D... 1,1 The second moving part 4 is subjected to a leftward suction force F from the first moving part 3. 1,1 In the magnetic domain D 2,1 The second moving part 4 is subjected to a rightward suction force F from the first moving part 3. 21 In the magnetic domain D 12 The second moving part 4 is subjected to a rightward suction force F from the first moving part 3. 1,2 In the magnetic domain D 2,2 The second moving part 4 is subjected to a leftward suction force F from the first moving part 3. 2,2 .

[0107] Assuming magnetic field pair D j =(D 1,j D2,j The resultant force corresponding to this is F. j (The positive and negative signs indicate different directions of the force). Taking the rightward direction as positive, the resultant force of the first moving part 3 on the second moving part 4 is:

[0108] F 第二动子组件 =-F1-F2=(-F 1,1 +F 2,1 )+(F 1,2 -F 2,2 )

[0109] The above can also be expressed as follows: the direction of the force is reflected in the sign of the component forces, as shown below:

[0110]

[0111] Similarly, the component forces -F acting on the second moving part 4 1,j and -F 2,j and its resultant force ∑-F 1,j and ∑-F 2,j The oscillator assembly 2 also forms a push-pull force structure.

[0112] Each component force is divided into pairs of paired magnetic domains, each corresponding to a different magnetic domain pair D. j The resultant force of the component forces, for example for the first moving part 3, is F1 = F 1,1 -F 2,1 And F2 = -F 1,2 +F 2,2 Then, the total resultant force can be calculated.

[0113] Further derive the formulas for the electromagnetic forces generated in each magnetic domain. The electromagnetic attraction acting on a magnetized ferromagnetic object is proportional to the total area of ​​the magnetic field lines passing through the magnetic poles and the square of the magnetic flux density. If the magnetic flux density B is uniformly distributed along the surface of the magnetic poles, and the calculated air gap length is small, then the formula for calculating the electromagnetic attraction is Maxwell's formula, and its expression is:

[0114]

[0115] F: Electromagnetic attraction

[0116] B: Magnetic flux density or magnetic induction intensity

[0117] Magnetic flux through a medium

[0118] S: Area of ​​magnetic field lines crossing magnetic poles

[0119] μ0: Air permeability

[0120] C: The correlation coefficient between the combination type and shape of the magnetic end faces, which has different values ​​for different scenarios. If it is the force generated between permanent magnets, it is denoted as C. m2m The value is usually taken as 1, and the accurate value is obtained through actual measurement during the design process; if the force between the permanent magnet and the conductive magnet (yoke) is..., then C... m2y The value is usually taken as 1 / 2, and the accurate value is obtained through actual measurement during the design process; if it is the force between the magnetic conductor (yoke) and the magnetic conductor (yoke), it is denoted as C. y2y It is usually taken as 1 / 4, and the accurate value is obtained through actual measurement during the design process.

[0121] 1)F j The calculation for j=1 corresponds to the magnetic field pair D. j =(D 1，j D 2，j ), j=1

[0122] Corresponding magnetic field pair D1=(D 1，1 D 2，1 The resultant force of the component forces is F1 = F 1，1 -F 2，1 The above formula is used to calculate the magnetic field D above. 1，1 and magnetic field D 2，1 The electromagnetic attraction in the middle includes:

[0127] Among them are:

[0128]

[0129]

[0130] because

[0131] F1 = F 1，1 -F 2，1

[0144] Therefore, D1 = (D 1，1 D 2，1 The resultant force of the component forces is:

[0145]

[0146] 2)F j The calculation for j=2 corresponds to the magnetic field pair D. j =(D 1，j D 2，j ), j=2

[0160] F 第一动子组件，nonlinear =F 1，nonlinear +F 2，nonlinear =0+0=0

[0161] For the second moving component 4, according to the action-reaction ratio, we have:

[0162]

[0163] F 第二动子组件，nonlinear =-F 第一动子组件，nonlinear =0

[0164] Although the first mover assembly 3 and the second mover assembly 4 are subjected to the same force in opposite directions, their oscillator subsystems are different. The first mover assembly 3 corresponds to spring 1 in the double-spring sheet, and the second mover assembly 4 corresponds to spring 2 in the double-spring sheet. Furthermore, the vibrating masses of the first mover assembly 3 and the second mover assembly 4 are also different. Therefore, the mechanical vibration systems and vibration equations of the first mover assembly 3 and the second mover assembly 4 are different.

[0165] From the above derivation process, the following characteristics can be observed:

[0171] in:

[0173]

[0174]

[0175] make

[0176] Where f r It is the electromagnetic interaction force between the moving parts.

[0177] The vibration equation of the double-moving oscillator is converted into its frequency, and its resonant frequency equation is solved as follows:

[0178] m1m2m3*ω 4 -((m1+m3)m2k3+(m1+m2)m3k2)*ω 2 +((m1+m2+m3)k2k3)=0

[0179] The above is a quadratic equation with two solutions:

[0180]

[0181] Assuming the target resonant frequencies of the double-moving oscillator are ω t1 and ω t2 ,

[0182] For a quadratic equation in one variable, assume it has two roots, i.e., ω. t1 and ω t2 :

[0183] m1m2m3*ω 4 -((m1+m3)m2k3+(m1+m2)m3k2)*ω 2 +((m1+m2+m3)k2k3)=0

[0184] Therefore:

[0185]

[0186]

[0187] Representing k3 using k2, we have:

[0188]

[0189] Solving the quadratic equation above, we can find the spring constant k2, and then substitute it into the formula to find k3.

[0190]

[0191] The formula above reveals the relationship between the spring constants k2 and k3 and the target resonant frequency ω. r1 and ω r2 And the relationship between m1, m2 and m3, using the target resonant frequency, to design the stiffness coefficient of the transmission plate in reverse, that is, assuming the resonant frequency ω. r1 and ω r2 By modifying the material and thickness of the vibration transducer, as well as the length and width of the vibration transmission limbs, the final stiffness coefficient values ​​can be made close to the calculated k2 and k3.

The first moving part assembly 3 and the second moving part assembly 4 are arranged in an alternating concave-convex interlocking shape. The closed curves of the main magnetic lines of the coils C1, C2 and C3 and the closed curves of the main magnetic lines of the permanent magnets M1 and M2 alternately pass through the first moving part assembly 3 and the second moving part assembly 4. There are 2N sets of magnetic domains inside the oscillator body 11.

[0249] The permanent magnets described in the parallel push-pull nonlinear cancelling moving iron and moving coil magnetic double-moving oscillators of Examples 1-12, or the magnets can be replaced with magnetic components, and the coils can be replaced with coil components, are also within the scope of protection of this patent.

[0250] A magnetic component: The overall magnetic field formed by a single magnet or a combination of multiple magnets (n>1) is equivalent to that of a single magnet. The magnetic field generated by the magnets in this combination is in the same direction as a dominant magnetic field (if the magnetic field strengths of the multiple magnets differ significantly, their magnetic field directions may be opposite, but the overall magnetic field direction is the same as the dominant magnetic field direction), thus the overall magnetic field generated can be considered equivalent to that produced by a single magnetic component. Magnets are typically connected by a rigid or flexible structural component (between magnets, at the edge of magnets, or around magnets), or even without a structural component, by means of bonding, welding, embedding, screws, screws, riveting, pins, clips, clamps, brackets, sleeves, caps, or other methods.

[0251] Coil assembly: The overall magnetic field generated by a single coil or an assembly of multiple coils (n turns > 1) is equivalent to the magnetic field generated by a single coil. The magnetic field generated by the coils in the assembly is in the same direction as the magnetic field generated by a dominant coil (if the magnetic field strengths of the multiple coils differ significantly, their directions may be opposite, but the overall magnetic field direction is the same as that of the dominant coil). Therefore, the overall magnetic field generated can be considered equivalent to the current generated in a single coil assembly. Coils are typically connected by a rigid or flexible structural component (between coils, at the edge of coils, or around coils), or even without a structural component, by bonding, welding, embedding, screws, screws, riveting, pins, clips, clamps, brackets, sleeves, caps, or other means.

The magnetic fields generated by the equivalent magnet (magnet 1|magnet 2|magnet 3), permanent magnet 4, and permanent magnet 5 are all oriented towards the Y+ axis, hence their directions are the same.

The magnetic field direction of permanent magnet 1 is towards the Y+ axis, and the magnetic field direction of permanent magnet 2 is towards the Y- axis. However, because the magnetic field strength of permanent magnet 2 is less than that of permanent magnet 1, the combination of permanent magnet 1 and permanent magnet 2, from the perspective of the overall external magnetic field direction, can still be considered similar to (indicated by the "=" sign in the figure) to a single magnet on the right.

Therefore, the overall magnetic field generated by the combination of coils 1, 2, and 3 can be viewed from the outside as being similar to (indicated by the "=" sign in the diagram) to the single coil on the right.

Coil 1 and the spacer ring, as well as coil 2 and the spacer ring, are connected by adhesive, brackets, sleeves, riveting, clamps, welding, or other methods. The magnetic fields generated by coil 1 and coil 2 are both oriented towards the Y-axis + direction, hence they are in the same direction. Therefore, the overall magnetic field generated by the combination of coil 1, the spacer ring, and coil 2 can be externally considered equivalent to (indicated by the "=" sign in the figure) to the single coil on the right.

The magnetic fields generated by the equivalent coil (coil 1|coil 2), coil 3, and coil 4 are all oriented towards the Y+ axis, hence their directions are the same. Therefore, the overall magnetic field direction generated by the coil combination (coil 3-(coil 1|coil 2)-coil 4) can be externally considered similar to (indicated by the "=" sign in the diagram) to the single coil on the right. The coil combination (coil 3-(coil 1|coil 2)-coil 4) can be considered as a single coil component 102.

The magnetic fields generated by both the equivalent coil (coil 1-coil 2-coil 3) and coil 4 are directed towards the Y+ axis, hence they are in the same direction. Therefore, the overall magnetic field direction generated by the coil combination ((coil 1-coil 2-coil 3)|coil 4) can be externally considered equivalent to (indicated by the "=" sign in the diagram) to the single coil on the right. The coil combination ((coil 1-coil 2-coil 3)|coil 4) can be considered as a single coil component 102.
