Description

Technical Field

[0001] This invention relates to the field of oscillator technology, specifically to the design method, apparatus, and application of a hybrid oscillator with nonlinear term cancellation and moving magnetic coil. 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 45 The figure shows the distortion curves of existing moving-coil or moving-magnet oscillators. 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] Additionally, please refer to the appendix. Figure 47 For a single-moving-magnet oscillator or a single-moving-coil oscillator, since there is only one oscillator system, there is only one resonant frequency point. 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 to the oscillator moves away from the resonant frequency, the amplitude of the oscillator's frequency response curve 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 design method for a hybrid oscillator with nonlinear term cancellation and moving magnet and moving coil.

[0006] Another object of the present invention is to provide a nonlinear term cancellation moving magnet moving coil hybrid oscillator designed using the above method.

[0007] Another object of the present invention is to provide an application of the nonlinear term cancellation moving magnet moving coil hybrid oscillator designed by the above method.

[0008] The technical solution of this invention is: a design method for a hybrid oscillator with nonlinear term cancellation and moving magnet and moving coil, comprising the following conditions:

[0009] (1): The oscillator body is provided, the oscillator body includes an outer cylinder, a first vibration plate and a second vibration plate, a first moving part assembly and a second moving part assembly, the first moving part assembly includes a magnet assembly structure, the second moving part assembly includes a coil assembly structure, the first moving part assembly is disposed inside the outer cylinder, the second moving part assembly is disposed inside the outer cylinder and located outside or inside the first moving part assembly, the first moving part assembly and the first vibration plate are fixedly connected through at least one point, and the second moving part assembly and the second vibration plate are fixedly connected through at least one point;

[0010] (2): The first moving part and the second moving part are simultaneously subjected to electromagnetic forces of two pairs of thrust and pull, respectively, exhibiting a push-pull structural feature.

[0011] This invention provides an improved design method, apparatus, and application for a hybrid oscillator with nonlinear term cancellation and moving magnet and moving coil, which, compared with the prior art, has the following improvements and advantages:

[0012] 1. This invention proposes a method to reduce the distortion of the oscillator by partially or completely canceling out the nonlinear term of the driving force on the moving magnet component and the moving coil component, or the nonlinear term of the acceleration of the two moving components, through a symmetrical or asymmetrical design.

[0013] 2. The nonlinear term cancellation 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.

[0014] 3. The nonlinear term cancellation hybrid oscillator of the present invention has two mover components, each connected to a separate spring plate, thus forming two independent oscillating subsystems, each corresponding to a vibration resonant frequency. Therefore, when a broadband signal is input to the oscillator system, the frequency response curve of the oscillator will be wider than that of an oscillator with a single mover component, resulting in better fidelity of the oscillator for broadband input signals.

[0015] 4. The nonlinear term cancellation hybrid oscillator of the present invention results in a uniform and balanced force on the oscillator, realizing the overall translational vibration of the oscillator and achieving the best vibration effect. Attached Figure Description

Detailed Implementation

[0061] 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.

[0062] For the design of canceling nonlinear terms, there are 2N magnetic domains inside the oscillator. The magnetic domains are paired and combined, and are defined as magnetic domain D. 1,i and D 2,iWhere i = 1, 2, 3, ..., N. The closed curves of the main magnetic field lines of the coil and the closed curves of 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.

[0063] 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.

[0064] 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).

[0065] Several types of magnetic domains:

[0066] 1) The space between the permanent magnets is filled with a medium (air, with a relative permeability slightly greater than 1).

[0067] 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:

[0068] 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.

[0069] 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.

[0070] 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.

[0071] like Figure 78 As shown, permanent magnet 1 and permanent magnet 2 are surrounded by air. The permanent magnets attract each other.

[0072] Magnetic domain D1: The spatial region enclosed by the air medium between permanent magnet 1 and permanent magnet 2.

[0073] Magnetic domain D2: The spatial region enclosed by the partial permanent magnet 2 and the air medium surrounding the partial permanent magnet 2.

[0074] Magnetic domain D3: The spatial region enclosed by all permanent magnets 1 and the air medium surrounding permanent magnets 1.

[0075] Magnetic domain D4: The spatial region enclosed by all permanent magnets 1 and 2, and the air medium surrounding permanent magnets 1 and 2.

[0076] Magnetic domain D5: The spatial region enclosed by air medium on the side of permanent magnet 2 away from permanent magnet 1.

[0077] Magnetic domain D6: The spatial region enclosed by the permanent magnet material medium surrounding part of the permanent magnet 1.

[0078] like Figure 79 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.

[0079] 2) The space between the permanent magnet and the magnetic conductor is filled with a medium (air, with a relative permeability close to 1).

[0080] 3) such as Figures 80-81 As shown, the space between the magnetic conductors is filled with a medium (air, with a relative permeability close to 1).

[0081] Magnetic domain D1: The spatial region enclosed by the air medium between magnetic conductor 1 and magnetic conductor 2.

[0082] 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.

[0083] 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.

[0084] Magnetic domain D4: The spatial region enclosed by all magnetic conductors 1 and 2, permanent magnets, and the air medium surrounding them.

[0085] Magnetic domain D5: The spatial region enclosed by the air medium on the side of conductor 2 away from magnetic conductor 1.

[0086] Magnetic domain D6: The spatial region enclosed by a permanent magnetic material medium surrounding a portion of the permanent magnet.

[0087] 4) such as Figure 82 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).

[0088] 5) The internal space of the permanent magnet is filled with a medium (permanent magnet material, relative permeability <1000).

[0089] like Figure 83 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.

[0090] 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.

[0091] Example 1

[0092] Please refer to Figure 1-44 as well as Figure 46 The design method for a hybrid oscillator with nonlinear terms canceled out by moving magnet and moving coil includes the following conditions:

[0093] (1): First, an oscillator body 1 is set up. The oscillator body 1 includes an outer cylinder 8, a first vibration plate 2 and a second vibration plate 3, a first moving part assembly 4 and a second moving part assembly 5. The first moving part assembly 4 includes a magnet assembly structure 6, and the second moving part assembly 5 includes a coil assembly structure 7. The first moving part assembly 4 is disposed inside the outer cylinder 8, and the second moving part assembly 5 is disposed inside the outer cylinder 8 and located outside or inside the first moving part assembly 4. The first moving part assembly 4 is fixedly connected to the first vibration plate 2 through at least one point, and the second moving part assembly 5 is fixedly connected to the second vibration plate 3 through at least one point.

[0094] (2): The first moving part 4 and the second moving part 5 are simultaneously subjected to electromagnetic forces of two pairs of pushing and pulling forces, presenting a push-pull structural feature.

[0095] (3): The number of permanent magnets in the magnet assembly structure 6 and the number of coils in the coil assembly structure 7 are limited, and the number of permanent magnets is N. 磁 The number of coils is N 圈 , making N 磁 >N 圈 Or N 磁 <N 圈 N 磁 For 1, 2, 3, ..., 100; N 圈 The range is 1, 2, 3, ..., 100;

[0096] The oscillator body 1 contains a 2N magnetic domain. A magnetic domain is a spatial region filled with electromagnetic energy, typically composed of air or a medium with low permeability (e.g., relative permeability <1000), including the region containing the magnet material. Magnetic domains are paired and defined as magnetic domain D. 1, i, D 2, i; The closed curves of the main magnetic field lines of coil 71 and permanent magnet 61 respectively cross the magnetic field domain D. 1, i, D 2, i, and in the magnetic domain D 1,i In the middle, the direction of the magnetic field lines of coil 71 is the same as the direction of the magnetic field lines of permanent magnet 61, while in the magnetic domain D... 2,i In the middle, the direction of the magnetic field lines of coil 71 is opposite to the direction of the magnetic field lines of permanent magnet 61; or in the magnetic domain D 1,i In the middle, the direction of the magnetic field lines of coil 71 is opposite to the direction of the magnetic field lines of permanent magnet 61, while in the magnetic domain D 2,i In the middle, the direction of the magnetic field lines of coil 71 is the same as the direction of the magnetic field lines of permanent magnet 61;

[0097] When the direction of the magnetic field lines of coil 71 passing through a certain magnetic field is the same as the direction of the magnetic field lines of permanent magnet 61, the total magnetic flux is equal to the sum of the magnetic flux generated by coil 71 and the magnetic flux generated by permanent magnet 61; when the direction of the magnetic field lines of coil 71 passing through a certain magnetic field is opposite to the direction of the magnetic field lines of permanent magnet 61, the total magnetic flux is equal to the difference between the magnetic flux generated by coil 71 and the magnetic flux generated by permanent magnet 61.

[0098] The first moving part 4 and the second moving part 5 are subjected to 2N forces F. 1,j and F 2,j j = 1, 2, 3, ..., N, N <= 100; each component force F 1,j and F 2,j Both consist of two parts: a linear term for the excitation current i and a nonlinear term for the excitation current i.

[0099] For the first moving component 4, F 第一动子组件,linear =K*i;

[0100] F 第一动子组件,nonlinear =F 1,nonlinear +F 2,nonlinear =0+0=0;

[0101] For the second moving component 5, according to the action-reaction ratio, we have:

[0102] F 第二动子组件,linear =-K*i;

[0103] F 第二动子组件,nonlinear =F 1,nonlinear +F 2,nonlinear =0+0=0

[0104] Where K is a function of the oscillator's design parameters;

[0105]

[0106] Among them, S D1,2 S D2,2 They are magnetic domain D 1,2 and D 2,2 The area of ​​the corresponding annular end face;

[0107] F: Electromagnetic attraction;

[0108] B: Magnetic flux density or magnetic induction intensity;

[0109] Magnetic flux through a medium;

[0110] S: Area of ​​magnetic field lines passing through magnetic poles;

[0111] μ0: air permeability;

[0112] G i Magnetic permeability of a magnetic circuit formed by the electromagnetic field generated by an electric current;

[0113] N: Number of coil turns;

[0114] C y2y The force between the conducting magnet (yoke) and the conducting magnet (yoke).

[0115] That is, the nonlinear terms in the component forces of the first mover assembly 4 and the second mover assembly 5 partially or completely cancel each other out.

[0116] In the first case, when the nonlinear terms are completely canceled out, F 第二动子组件,nonlinear and F 第一动子组件,nonlinear =0, meaning that the resultant force and excitation current of the first moving part 4 and the second moving part 5 have only linear terms, and therefore are always linearly related;

[0117] In another case, the nonlinear terms in the forces acting on the first mover assembly 4 and the second mover assembly 5 partially cancel each other out and decrease.

[0118] This causes the linear terms in the forces acting on the first mover assembly 4 and the second mover assembly 5 to be superimposed and increased, thus obtaining the nonlinear term-canceling moving magnet-moving coil hybrid oscillator.

[0119] The first moving part 4 and the second moving part 5 are arranged in an interlocking, concave-convex shape, and the closed curve of the main magnetic field line of the coil and the closed curve of the main magnetic field line of the permanent magnet alternately pass through the first moving part 4 and the second moving part 5, respectively.

[0120] In one case, the following conditions also apply:

[0121] (3.1): Looking outward from the center, the permanent magnet is inside and the coil is outside;

[0122] (3.2):(N 磁 N 圈) = (j, j+1)*n; j = 1, 2, 3…; n is a natural number, n = 1, 2, 3…;

[0123] (3.3): When N 磁 When N > 1, the polarity of the two opposite end faces of the permanent magnet is the same; when N 圈 When the value is greater than 1, the current in adjacent coils is in the opposite direction, and the electromagnetic fields of two adjacent coils and their two adjacent end faces have the same polarity.

[0124] (3.4): If multiple permanent magnets are arranged symmetrically, the symmetrical permanent magnets have the same size and magnetic force parameters;

[0125] (3.5): If multiple coils are arranged symmetrically, the symmetrical coils have the same size and current value.

[0126] In another case, the following conditions also apply:

[0127] (3.1): Looking outward from the center, the permanent magnet is inside and the coil is outside;

[0128] (3.2):(N 磁 N 圈) = (j+1,j)*n; j = 1, 2, 3…; n is a natural number, n = 1, 2, 3…;

[0129] (3.2): When N 磁 When N > 1, the polarity of the two opposite end faces of the permanent magnet is the same; when N 圈 When the value is greater than 1, the current in adjacent coils flows in opposite directions, and the current in two adjacent coils flows in opposite directions.

[0130] The electromagnetic fields of two adjacent end faces have the same polarity;

[0131] (3.4): If multiple permanent magnets are arranged symmetrically, the symmetrical permanent magnets have the same size and magnetic force parameters;

[0132] (3.5): If multiple coils are arranged symmetrically, the symmetrical coils have the same size and current value.

[0133] In this structure, the first moving element assembly 4 and the second moving element assembly 5 move independently. When the first magnetic conductor is used in the magnet assembly structure 6, the magnetic resistance is low, resulting in better vibration. However, when the first non-magnetic conductor is used, the magnetic resistance is high, resulting in weaker vibration, but it can still be applied in some scenarios. Similarly, when the coil assembly structure 7 uses the second magnetic conductor, the magnetic resistance is low, resulting in better vibration. When the second non-magnetic conductor is used, the magnetic resistance is high, resulting in weaker vibration, but it can still be applied in some scenarios.

[0134] The first vibration plate 2 and the second vibration plate 3 can be rectangular, circular, racetrack-shaped or three-dimensional structures depending on the application scenario. The first vibration plate 2 and the second vibration plate 3 can also use a double spring vibration plate device, which can be used in combination according to different application scenarios. The first vibration plate 2 and the second vibration plate 3 are usually fixed on the top or bottom surface of the outer cylinder 8.

[0135] The first stator assembly is fixed inside the outer cylinder 8, and the second stator assembly is disposed outside the first stator assembly;

[0136] The first moving part 4 is fixedly connected to the first vibration transmission plate 2 through at least one point, which includes point contact and surface contact, and can be one point, two points, or multiple points.

[0137] The second moving part 5 is fixedly connected to the second vibration plate 3 through at least one point, which includes point contact and surface contact, and can be one point, two points, or multiple points.

[0138] Example 2

[0139] Please refer to Figure 1-9 The nonlinear term cancellation moving magnet-moving coil hybrid oscillator device designed using the method of Embodiment 1 includes an oscillator body 1, which includes a first transmission plate 2 and a second transmission plate 3, a first moving element assembly 4 and a second moving element assembly 5. The first moving element assembly 4 includes a magnet assembly structure 6, and the second moving element assembly 5 includes a coil assembly structure 7. The first moving element assembly 4 is disposed inside an outer cylinder 8, and the second moving element assembly 5 is disposed inside the outer cylinder 8 and located outside the first moving element assembly 4. The first moving element assembly 4 and the first transmission plate 3 are connected. The vibrating plate 2 is fixedly connected to the second vibrating plate 3 through at least one point. The second moving part assembly 5 is fixedly connected to the second vibrating plate 3 through at least one point. The magnet assembly structure 6 includes a permanent magnet 61 and a first magnetic conductor or a first non-magnetic conductor 62. The coil assembly structure 7 includes a coil 71 and a second magnetic conductor or a second non-magnetic conductor 72. The magnet assembly structure 6 also includes a magnetic disk 63. The coil assembly structure 7 also includes a magnetic ring 73. Viewed from the center outward, the coil 71 is on the outside and the permanent magnet 61 is on the inside. There is one permanent magnet 61. There are two coils 71, with the currents in adjacent coils 71 flowing in opposite directions. The electromagnetic fields at the two adjacent end faces of the two coils 71 have the same polarity. The first transducer 2 is fixed to the top surface of the outer cylinder 8. The permanent magnet 61 has a first magnetically conductive body or a first non-magnetically conductive body 62 fixed on both sides, one of which is fixed to the first transducer 2. The second transducer 3 is integral with the first transducer 2, and the second transducer 3 extends obliquely from the outer periphery of the plane containing the first transducer 2 toward the inner wall of the outer cylinder 8. The coils 71 are respectively fixed on both sides of the second magnetic conductor or the second non-magnetic conductor 72.

Figure 6 air gap D 1,1 Constitutes the magnetic field of action D 1,1 Within the magnetic field domain, the total magnetic flux / magnetic induction intensity generated by the superposition of the magnetic field generated by the permanent magnet 61 and the electromagnet generated by the coil 71 causes the components around the magnetic field to generate an interaction force.

[0142] The magnetic field domains D formed by the four air gaps 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 field produced by the permanent magnet and the magnetic field produced by the coil electromagnet causes interaction forces to be generated in the components surrounding the magnetic field domain. The magnetic field D above... 1,1 D 2,1 D 1,2 D 2,2 Both are surrounded by the first mover assembly 4 and the second mover assembly 5. Therefore, in these magnetic domains, the first mover assembly 4 and the second mover assembly 5 will generate interacting component forces.

[0143] Please refer to the appendix. Figure 7 The current through coil C1 is i1, the current through coil C2 is i2, and the corresponding magnetic fluxes of the coils are Φ and Φ, respectively. i1 and Φ i2 The magnetic flux corresponding to the permanent magnet M is Φ. M .

[0144] Magnetic domain D 1,1 D 2,1 D 1,2 D 2,2 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 ).

[0145] 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

[0146] In magnetic domain D 1,1 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 magnet M1. Therefore, in the magnetic domain D... 1,1 In the middle, the total magnetic flux is Φ i1 and Φ M1 =Φ m The added value. In the magnetic domain D 2,1 In the magnetic field, the direction of the magnetic field lines corresponding to coil C2 is opposite to the direction of the magnetic field lines corresponding to permanent magnet M1. 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 difference.

[0147] Assume i1 = i2 = i, Φ i1 =Φ i2 =Φ i If the magnetic field lines of magnet M are in the positive direction and the magnetic flux is also positive, then we have

[0148] Φ D1,1 =Φ M1 +Φ i1 =Φ m +Φ i

[0149] Φ D2,1 =Φ M1 -Φ i2 =Φ m -Φ i

[0150] 2) Magnetic domain to D j =(D 1,j D 2,jWhen i = 2, that is, the magnetic field pair (D) 1,2 D 2,2 ) magnetic flux

[0151] In magnetic domain D 1,2 In the middle, only the magnetic field lines corresponding to coil C1 pass through, therefore the total magnetic flux is only Φ. i1 =Φ i In the magnetic domain D 2,2 In the middle, only the magnetic field lines corresponding to coil C2 pass through, therefore the total magnetic flux is only Φ. i2 =Φ i .

[0152] Assume that the magnetic reluctance of the magnetic circuit formed by the electromagnetic field generated by the current i in coils C1 and C2 is Z. i Let N be the number of turns in coils C1 and C2, and i be the current intensity. Then we have:

[0153]

[0154] Assume the permeability of the magnetic circuit formed by the electromagnetic field generated by the current is G. i Then we have:

[0155]

[0156] The magnetic flux corresponding to a permanent magnet can also be expressed using the formula for magnetic induction intensity. Assume the magnetic induction intensities at the extreme ends of permanent magnet M1 are B... m The area of ​​the magnetic pole end is S. m It can be obtained that...

[0157] Therefore,

[0158]

[0159]

[0160] Please refer to the appendix. Figure 5 Draw the closed magnetic field lines of coils C1 and C2, as well as the closed magnetic field line of magnet M1. In the diagram, the closed magnetic field lines generated by coil C1 pass through the magnetic gap D. 1,1 D 1,2 The closed magnetic field lines generated by coil C2 pass through the magnetic gap D. 2,1 D 2,2 The closed magnetic field lines generated by magnet M1 pass through the magnetic gap D in sequence. 1,1 D 2,1 .

[0161] Please refer to Figure 8 , Figure 8 It is the first moving component 4, magnetic domain D 1,1 D2,1 D 1,2 D 2,2 The diagram showing the relationship between the second moving part component 5 and the force analysis diagram isolated from the first moving part component 4 is also included. In the magnetic domain D... 1,1 The first moving part 4 is subjected to a rightward suction force F from the second moving part 5. 1,1 In the magnetic domain D 2,1 The first moving part 4 is subjected to a leftward suction force F from the second moving part 5. 2,1 In the magnetic domain D 1,2 The first moving part 4 is subjected to a leftward suction force F from the second moving part 5. 1,2 In the magnetic domain D 2,2 The first moving part 4 is subjected to a rightward suction force F from the second moving part 5. 2,2 .

[0162] 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 stator assembly on the mover assembly is...

[0163] F 第一动子组件 =F1+F2=F 1,1 -F 2,1 -F 1,2 +F 2,2

[0164] F 第一动子组件 =F1+F 2＝ (F 1,1 -F 2,1 )+(-F 1,2 +F 2,2 )

[0165] Where F j It corresponds to the magnetic field pair D j =(D 1,j D 2,j The combined force of ).

[0166] Similarly, Figure 9 This is the force analysis diagram isolated from the second mover assembly 5. According to Newton's third law, for every action, there is an equal and opposite reaction. The second mover assembly 5 experiences a component force -F from the first mover assembly 4. 1,1 -F 2,1 -F 1,2 -F 2,2 Their combined force is:

[0167] F 第二动子组件 =-F1-F2=-(F 1,1-F 2,1 )-(-F 1,2 +F 2,2 )

[0168] 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:

[0169]

[0170] 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, F1 = F 1,1 -F 2,1 And F2 = -F 1,2 +F 2,2 Then calculate the total resultant force.

[0171] 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:

[0172]

[0173] F: Electromagnetic attraction

[0174] B: Magnetic flux density or magnetic induction intensity

[0175] Magnetic flux through a medium

[0176] S: Area of ​​magnetic field lines crossing magnetic poles

[0177] μ0: Air permeability

[0178] 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.

[0179] 1)F j,The calculation for j=1 corresponds to the magnetic field pair D. j =(D 1,j D 2,j ), j=1

[0180] 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:

[0181]

[0182] Among them, S D1,1 S D2,1 They are magnetic domain D 1,1 and D 2,1 The area of ​​the corresponding annular end face, and S D1,1 =S D2,1 =S D Therefore:

[0183]

[0184]

[0185] Among them are:

[0186]

[0187]

[0188] because

[0189] F1 = F 1，1 -F 2，1

[0190] Then there is

[0191] F1 = F 1，linear +F 1，nonlinear

[0192]

[0193] F 1，1，linear F 2，1，linear F 1，1，nonlinear F 1，1，nonlinear Substitute F respectively 1，linear and F 1，nonlinear The calculations are as follows:

[0194]

[0195] because

[0196]

[0197]

[0198] Therefore:

[0199]

[0200] Similarly, calculate F. 1，nonlinear

[0201]

[0202] Therefore, D1 = (D 1，1 D 2，1 The resultant force of the component forces is:

[0203]

[0204] 2)F j The calculation for j=2 corresponds to the magnetic field pair D. j =(D 1，j D 2，j ), j=2

[0205] Corresponding magnetic field pair D2=(D 1，2 D 2，2 The resultant force of the component forces is F2 = -F 1，2 +F 2，2 Calculate the magnetic field D above. 1，2 and magnetic field D 1，2 The electromagnetic attraction in the middle includes:

[0206]

[0207] Among them, S D1，2 S D2，2 They are magnetic domain D 1，2 and D 2，2 The area of ​​the corresponding annular end face, and S D1，2 =S D2，2 =S D Therefore:

[0208]

[0209] Therefore,

[0210]

[0211] It can be obtained

[0212]

[0213] Because of the net force acting on the first moving part 4

[0214] F 第一动子组件 =F1+F2

[0215] F 第一动子组件 =F 第一动子组件，linear +F 第一动子组件，nonlinear

[0216] all:

[0217]

[0218] F 第一动子组件，nonlinear =F 1，nonlinear +F 2，nonlinear =0+0=0

[0219] For the second moving component 5, according to the action-reaction ratio, we have:

[0220]

[0221] F 第二动子组件，nonlinear =-F 第一动子组件，nonlinear =0

[0222] Although the first mover assembly 4 and the second mover assembly 5 are subjected to the same force in opposite directions, their oscillator systems are different. The first mover assembly 4 corresponds to spring 1 in the double-spring sheet, and the second mover assembly 5 corresponds to spring 2 in the double-spring sheet. Furthermore, the vibrating masses of the first mover assembly 4 and the second mover assembly 5 are also different; therefore, their mechanical vibration systems and vibration equations are different.

[0223] From the above derivation process, the following characteristics can be observed:

[0224] 1) In the linear term of the resultant force F 动子组件，linear In the middle, the component force F 1，linear and F 2，linear The linear terms of each individual are superimposed to form the resultant linear term F. 动子组件，linear The relationship between the coil current and the coil current remains linear.

[0225] In the nonlinear term of resultant force F 动子组件，nonlinear In the middle, the component force F 1，nonlinear and F 2，nonlinear Their respective nonlinear terms cancel each other out, thus the resultant nonlinear term F 动子组件，nonlinear It is zero.

Then the magnetic flux of each coil is Φ. i1 , Φi2 and Φ i3 For the sake of simplicity, assume Φ i1 =Φ i2 =Φ i3 =Φ i (Another possibility is that the number of turns N1, N2, and N3 of coils C1, C2, and C3 are such that N1 = N3 ≠ N2, or that the magnetic circuit structure of C1, C2, and C3 causes the magnetic reluctance of C2 to be different from that of C1 and C3, thus making Φ...) i1 =Φ i3 ≠Φ i2 In this case, because it is still a symmetrical design, the conclusion that the nonlinear terms in the resultant force of the paired forces cancel each other out still holds.

[0238] In magnetic domain D 1,1 In the magnetic field, the direction of the magnetic field lines corresponding to coil C2 is opposite to the direction of the magnetic field lines corresponding to permanent magnet M1. 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 C2 is the same as the direction of the magnetic field lines corresponding to permanent magnet M2.

[0241] Φ D2,1 =Φ M2 +Φ i2 =Φ m +Φ i2

[0242] 2) Magnetic domain to D j =(D 1,j D 2,j ), j=2

[0243] In magnetic domain D 1,2 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 magnet M1. Therefore, in the magnetic domain D... 1,2 In the middle, the total magnetic flux is Φ i1 =Φ i3 and Φ M1 =Φ m The added value. In the magnetic domain D 2,2 In the magnetic field, the direction of the magnetic field lines corresponding to coil C3 is opposite to the direction of the magnetic field lines corresponding to permanent magnet M2. Therefore, in the magnetic field domain D... 2,2 In the middle, the total magnetic flux is Φ i3 =Φ i1 and Φ M2 =Φ m The difference.

[0244] Assume i1 = i2 = i3 = i, Φ i1 =Φ i3 ≠Φ i2 Assuming that the magnetic field lines of the permanent magnet are in the positive direction and the magnetic flux is also positive in each magnetic domain, then we have

[0245] Φ D1,2 =Φ M1 +Φ i1 =Φ m +Φ i1

[0246] Φ D2,2 =Φ M1 -Φ i3 =Φ m -Φ i1

[0247] 3) Magnetic domain to D j=(D 1,j D 2,j ), j=3

[0248] In magnetic domain D 1,3 In the middle, only the magnetic field lines corresponding to coil C1 pass through, therefore the total magnetic flux is only Φ. i1 In the magnetic domain D 2,3 In the middle, only the magnetic field lines corresponding to coil C3 pass through, therefore the total magnetic flux is only Φ. i3 =Φ i1 .

[0249] Assume that the magnetic reluctance of the magnetic circuit formed by the electromagnetic field generated by the current i in coils C1, C2, and C3 is Z. i Let N be the number of turns in coils C1, C2, and C3, and i be the current intensity. Then:

[0250]

[0251] Assume the permeability of the magnetic circuit formed by the electromagnetic field generated by the current is G. i Then we have:

[0252]

[0253] Another possibility is that the number of turns N1, N2, and N3 of coils C1, C2, and C3 are such that N1 = N3 ≠ N2, or that the magnetic circuit structure of C1, C2, and C3 causes the reluctance of C2 to be different from that of C1 and C3, i.e., G i,1 =G i,3 ≠G i,2 , thus Φ i1 =Φ i3 ≠Φ i2 In this case, because it is still a symmetrical design, the conclusion that the nonlinear terms in the resultant force of the paired forces cancel each other out still holds. Therefore:

[0254]

[0255]

[0256] The magnetic flux of a permanent magnet can also be expressed using the formula for magnetic induction intensity. Assume that the magnetic induction intensity at the extreme ends of permanent magnets M1 and M2 is both B. m The area of ​​the magnetic pole end is S. m It can be obtained that...

[0257] Therefore,

[0258]

[0259]

[0260]

[0261] In another scenario: the number of turns N1, N2, and N3 of coils C1, C2, and C3 are such that N1 = N3 ≠ N2, or the magnetic circuit structure of C1, C2, and C3 causes the reluctance of C2 to be different from that of C1 and C3, i.e., G i,1 =G i,3 ≠G i,2 , thus Φ i1 =Φ i3 ≠Φ i2 The formula above becomes:

[0262]

[0263]

[0264]

[0265] As can be seen from the formula above, when N1 = N3, G i,1 =G i,3 Then the magnetic field pair D2=(D 1,2 D 2,2 ), and magnetic field pair D1=(D 1,1 D 2,1 ), D3=(D 1,3 D 2,3 The magnetic flux in the force still possesses the property that the nonlinear terms of the current in the corresponding component force can be canceled out.

[0266] Figure 17 This is a schematic diagram of the oscillator subsystem consisting of the first moving element assembly 4 and the springs in the transmission plate. The magnetic domain D... 1,1 D 2,1 D 1,2 D 2,2 D 1,3 D 2,3 The positional relationship between the first moving part 4 and the second moving part 5 is also explained. In the magnetic domain D... 1,1 The first moving part 4 is subjected to a leftward suction force F from the second moving part 5. 1,1 In the magnetic domain D 2,1 The first moving part 4 is subjected to a rightward suction force F from the second moving part 5. 2,1 In the magnetic domain D 1,2 The first moving part 4 is subjected to a rightward suction force F from the second moving part 5. 1,2 In the magnetic domain D 2,2 The first moving part 4 is subjected to a leftward suction force F from the second moving part 5. 2,2 In the magnetic domain D1,3 The first moving part 4 is subjected to a leftward suction force F from the second moving part 5. 1,3 In the magnetic domain D 2,3 The first moving part 4 is subjected to a rightward suction force F from the second moving part 5. 2,3 Define the magnetic field pair D j =(D 1,j D 2,j The resultant force corresponding to this magnetic field is the force exerted by the magnetic field on D. j The corresponding resultant force F j =F 1,j +F 2,j Assuming rightward is the positive direction, then when F... 1,j and F 2,j When the direction is to the right, then F 1,j and F 2,j The sign in F is positive; then when F 1,j and F 2,j When the direction is to the left, then F 1,j and F 2,j The sign in the equation is negative. Therefore, the net force exerted on the first moving component 4 by the second moving component 5 is...

[0267] F 第一动子组件 =F1+F2+F3=-F 1,1 +F 2,1 +F 1,2 -F 2,2 +-F 1,3 +F 2,3

[0268] F 第一动子组件 =F1+F2+F3=(-F 1,1 +F 2,1 )+(F 1,2 -F 2,2 )+(-F 1,3 +F 2,3 )

[0269] F above j Corresponding magnetic field pair D j =(D 1,j D 2,j The resultant force of the component forces that generate forces on the moving part component.

[0270] Similarly, Figure 18 This is the force analysis diagram isolated from the second mover assembly 5. According to Newton's third law, for every action, there is an equal and opposite reaction. The second mover assembly 5 experiences a component force -F from the first mover assembly 4. 1，1 -F 2，1 -F 1，2 -F 2,2 -F 1，3-F 2,3 Their combined force is:

[0271] F 第二动子组件 =-F1-F2-F3

[0272] =(F 1，1 -F 2，1 )+(-F 1，2 +F 2，2 )+(F 1，3 -F 2，3 )

[0273] The above can also be expressed as follows: assuming that the algebraic signs of the component forces simultaneously indicate the direction of the force through positive and negative signs, then:

[0274]

[0275] We first calculate the resultant force of the component forces generated in each pair of paired magnetic domains, that is, we calculate the resultant force of each pair of magnetic domains D1 = (D 1，1 D 2,1 The resultant force F1 = -F 1，1 +F 2,1 Magnetic domain pair D2=(D 1，2 D 2,2 The resultant force F1 = F 1,2 -F 2,2 Magnetic domain pair D3=(D 1，3 D 2，3 The resultant force F3 = -F 1，3 +F 2，3 Then calculate the total resultant force.

[0276] First, derive the formula for the electromagnetic force generated in each magnetic field. The magnitude of 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:

[0277]

[0278] F: Electromagnetic attraction

[0279] B: Magnetic flux density or magnetic induction intensity

[0280] Magnetic flux through a medium

[0281] S: Area of ​​magnetic field lines crossing magnetic poles

[0282] μ0: Air permeability

[0283] 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, then 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.

[0284] 1) Magnetic domain to D j =(D 1，j D 2，j When j=1, that is, D1=(D1, D... 2，1 The corresponding resultant force F1 = -F 1，1 +F 2，1

[0285] 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:

[0286]

[0287] Among them, S D1，1 S D2，1 They are magnetic domain D 1，1 The area of ​​the annular end face corresponding to D2,1, and S D1，1 =S D2，1 =S D1 Therefore:

[0288]

[0289]

[0290] Among them are:

[0291]

[0292]

[0293] because

[0294] F1 = -F 1，1 +F 2，1

[0295] Then there is

[0296] F1 = F 1，linear +F 1，nonlinear

[0297]

[0298] F 1，1，linear F 2，1，linear F 1，1，nonlinear F 1，1，nonlinear Substitute F respectively 1，linear and F 1，nonlinear The calculations are as follows:

[0299]

[0300] because

[0301]

[0302]

[0303] Therefore:

[0304]

[0305] Similarly, calculate F. 1，nonlinear ,

[0306]

[0307] Thus, the magnetic field affects D 1，1 and D 2，1 The corresponding resultant force is:

[0308]

[0309] 2) Magnetic domain to D j =(D 1，j D 2，j When j=2, that is, D2=(D 1，2 D 2，2 The corresponding resultant force F2 = F 1，2 -F 2，2

[0310] The above formula is used to calculate the magnetic field D above. 1，2 and magnetic field D 2，2 The electromagnetic attraction in the middle includes:

[0311]

[0312] Among them, S D1，2 S D2，2 They are magnetic domain D 1，2 and D 2，2 The area of ​​the corresponding annular end face, and S D1，2 =S D2，2 =S D2 Therefore:

[0313]

[0314]

[0315] Among them are:

[0316]

[0317]

[0318] because

[0319] F2 = F 1，2 -F 2，2

[0320] Then there is

[0321] F2 = F 2，linear +F 2，nonlinear

[0322]

[0323] F 1，1，linear F 2，1，linear F 1，1，nonlinear F 1，1，nonlinear Substitute F respectively 1，linear and F 1，nonlinear The calculations are as follows:

[0324]

[0325]

[0326] because

[0327]

[0328]

[0329] Therefore:

[0330]

[0331] Similarly, calculate F. 2，nonlinear ,

[0332]

[0333] Thus, the magnetic field affects D 1，1 and D 2，1 The corresponding resultant force is:

[0334]

[0335] 3) Magnetic domain pair (D 1，j D2，j When j=3, that is, D3=(D 1，3 D 2，3 The corresponding resultant force F3 = -F 1，3 +F 2，3

[0336] Calculate the magnetic field D above 1，3 and magnetic field D 1，3 The electromagnetic attraction in the middle includes:

[0337]

[0338] Among them, S D1，3 S D2，3 They are magnetic domain D 1，3 and D 2，3 The area of ​​the corresponding annular end face, and S D1，3 =S D2，3 =S D3 Therefore:

[0339]

[0340] Therefore,

[0341]

[0342] It can be obtained

[0343]

[0344] 4) Calculate the resultant force on the first moving part 4.

[0345] F 第一动子组件 =F1+F2+F3

[0346] F 第一动子组件 =F 第一动子组件，linear +F 第一动子组件，nonlinear

[0347] all:

[0348]

[0349] F 动磁，nonlinear =F 1，nonlinear +F 2，nonlinear +F 3，nonlinear =0+0+0=0

[0350] For the second moving component 5, according to the action-reaction ratio, we have:

[0351]

[0352] F 第二动子组件，nonlinear =-F 第一动子组件，nonlinear =0

[0353] Although the first mover assembly 4 and the second mover assembly 5 are subjected to the same force in opposite directions, their oscillator subsystems are different. The first mover assembly 4 corresponds to spring 1 in the double-spring sheet, and the second mover assembly 5 corresponds to spring 2 in the double-spring sheet. Furthermore, the vibrating masses of the first mover assembly 4 and the second mover assembly 5 are also different; therefore, their mechanical vibration systems and vibration equations are different.

[0354] From the above derivation process, the following characteristics can be observed:

[0355] 1) In the linear term of the resultant force F 动子组件，linear In the middle, the magnetic field component force F 1，linear F 2，linear and F 3，linear The linear terms of each are superimposed to form the resultant linear term F. 动子组件，linear The relationship between the coil current and the coil current remains linear.

[0356] 2) In the resultant nonlinear term F 动子组件，nonlinear In the middle, the magnetic field component force F 1，nonlinear F 2，nonlinear and F 3，nonlinear Their respective nonlinear terms cancel each other out.

[0357] Therefore, the resultant nonlinear term F 动子组件，nonlinear It is zero.

[0358] We call the above design a hybrid moving magnet moving coil bone conduction oscillator or actuator design method with nonlinear term cancellation.

In the magnetic domain D 2,1 In the magnetic field, the direction of the magnetic field lines corresponding to coil C is the same as the direction of the magnetic field lines corresponding to permanent magnet 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.

[0393] 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:

[0394]

[0395] 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 4, is F1 = F 1,1 -F 2,1 And F2 = -F 1,2 +F 2,2 Then, the total resultant force can be calculated.

[0396] 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:

[0397]

[0398] F: Electromagnetic attraction

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.

[0404] 1)F j, The calculation for j=1 corresponds to the magnetic field pair D. j =(D 1,j D 2,j ), j=1

[0405] 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:

[0408]

[0409]

[0410] Among them are:

[0411]

[0412]

[0413] because

[0414] F1 = F 1，1 -F 2，1

[0415] Then there is

[0425] Similarly, calculate F. 1，nonlinear ,

[0426]

[0427] Therefore, D1 = (D 1，1 D 2，1 The resultant force of the component forces is:

[0428]

[0435] Therefore,

[0436]

[0437] It can be obtained

[0438]

[0439] Because of the net force acting on the first moving part 4

[0440] F 第一动子组件 =F1+F2

[0441] F 第一动子组件 =F 第一动子组件，linear +F 第一动子组件，nonlinear

[0442] all:

[0443]

[0444] F 第一动子组件，nonlinear =F 1，nonlinear +F 2，nonlinear =0+0=0

[0445] For the second moving component 5, according to the action-reaction ratio, we have:

[0446]

[0447] F 第二动子组件，nonlinear =-F 第一动子组件，nonlinear =0

[0448] Although the first mover assembly 4 and the second mover assembly 5 are subjected to the same force in opposite directions, their oscillator subsystems are different. The first mover assembly 4 corresponds to spring 1 in the double-spring sheet, and the second mover assembly 5 corresponds to spring 2 in the double-spring sheet. Furthermore, the vibrating masses of the first mover assembly 4 and the second mover assembly 5 are also different; therefore, their mechanical vibration systems and vibration equations are different.

[0449] From the above derivation process, the following characteristics can be observed:

[0450] 1) In the linear term of the resultant force F 动子组件，linear In the middle, the component force F 1，linear and F 2，linear The linear terms of each individual are superimposed to form the resultant linear term F. 动子组件，linear The relationship between the coil current and the coil current remains linear.

[0451] In the nonlinear term of resultant force F 动子组件，nonlinear In the middle, the component force F 1，nonlinear and F 2，nonlinear Their respective nonlinear terms cancel each other out, thus the resultant nonlinear term F 动子组件，nonlinear It is zero.

[0463] The permanent magnets described in the nonlinear term cancellation moving magnet-moving coil hybrid oscillators in Examples 1-13, or magnets that can be replaced with magnetic components, and coils that can be replaced with coil components, are all within the scope of protection of this patent.

[0464] 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.

[0465] 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.

[0466] To describe the magnet and coil components in detail, the following embodiments are provided for specific description.

[0467] The magnet 201 is used in the following embodiments;

The magnetic fields generated by permanent magnet 1 and permanent magnet 2 are both oriented towards the Y+ axis, hence they are in the same direction. Therefore, the combination of permanent magnet 1 and permanent magnet 2, from the perspective of the overall external magnetic field direction, can be considered similar to (indicated by the "=" sign in the figure) to the single magnet on the right. The combination of permanent magnet 1 and permanent magnet 2 can be considered as a single magnet component 201.

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 fields generated by the equivalent magnet (Magnet 1-Magnet 2-Magnet 3), permanent magnets 4, and permanent magnet 5 are all oriented towards the Y+ axis, hence their directions are the same. Therefore, the magnet combination (Magnet 4|(Magnet 1-Magnet 2-Magnet 3)|Magnet 5), from the perspective of the overall external magnetic field direction, can be considered similar to (indicated by the "=" sign in the diagram) a single magnet on the right.

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.
