Description

Technical Field

[0001] The present invention relates to the field of transducer devices, and in particular to a micro-electromagnetic element, an electromagnetic transducer and an electronic device. Background Art

[0002] Electromagnetic transducers are devices that use the interaction between the magnetic field generated by a current-carrying conductor and the magnetic field generated by a magnetic element to drive the current-carrying conductor to move. Electromagnetic transducers are widely used. For example, electromagnetic transducers can be used in speakers to drive the diaphragm to vibrate and drive the speaker to sound. Electromagnetic transducers can also be used in solenoid valves to drive the valve core to move and drive the solenoid valve to open and close.

[0003] In the existing electromagnetic transducers, the current-carrying conductor generally adopts a coil element, which is formed by winding a metal wire and is in a ring shape, while the magnetic element (such as a magnet) passes through the coil element or is sleeved on the coil element, and the magnetic lines of force between the coil element and the magnetic element are radial; since the coil element is in a ring shape, it is necessary to consider the gap setting in the 360° direction between the magnetic element and the coil element to avoid collision between the magnetic element and the coil element; therefore, the gap between the magnetic element and the coil element will be set larger (such as the gap between the magnetic element and the coil element in the earphone needs to be at least 1.2mm), and the larger the gap between the magnetic element and the coil element, the greater the magnetic resistance between the coil element and the magnetic element, which reduces the interaction force between the coil element and the magnetic element; in addition, the magnetic element and the coil element are sleeved on each other, so that the sizes of the magnetic element and the coil element are mutually restricted, resulting in that the size of one of the magnetic element and the coil element cannot be made very large, which also affects the interaction force between the coil element and the magnetic element. Summary of the invention

[0009] The positive conductive end and the negative conductive end are respectively provided with a positive conductive hole and a negative conductive hole.

[0010] When the number of the component layers is at least two, the positive conductive ends and the negative conductive ends of adjacent component layers are connected to each other so that the adjacent component layers are connected in series or in parallel.

[0011] The substrate of at least one element layer is provided with a magnetic conductor.

[0012] The substrate of the component layer is made of one of silicon, ceramic, glass, sapphire, LDS plastic, germanium, gallium arsenide, indium phosphide, gallium nitride, silicon carbide, BT, ABF, bakelite, glass fiber, plastic or zinc selenide.

[0013] Each conductive segment of the component layer is in a straight line segment structure, and each conductive segment of the component layer is parallel to each other.

[0014] An electromagnetic transducer comprises at least one magnetic element for generating a driving magnetic field and the micro-electromagnetic element as described above; the micro-electromagnetic element is movably arranged in the driving magnetic field; when current flows through each conductive segment of the micro-electromagnetic element, the micro-electromagnetic element interacts with the driving magnetic field generated by the magnetic element to cause the micro-electromagnetic element to move.

[0015] There are two magnetic elements, which are divided into a first magnetic element and a second magnetic element. The first magnetic element and the second magnetic element are arranged opposite to each other, so that the driving magnetic field generated between the first magnetic element and the second magnetic element is a parallel magnetic field.

It should be noted that the present invention can also be that the first end of the partial conductive segment 12 of the component layer 1 is connected to the positive conductive end 13 of the component layer 1, and the second end of the partial conductive segment 12 of the component layer 1 is connected to the negative conductive end 14 of the component layer 1. This can also facilitate the conductive segment 12 to access the external current through the positive conductive end 13 and the negative conductive end 14.

[0027] Cooperate Figure 2 As shown, in the second embodiment of the micro electromagnetic element C of the present invention, each conductive segment 12 of the element layer 1 is also in a straight segment structure, and the conductive segment 12 of the element layer 1 is divided into at least two micro segment areas 120, each micro segment area 120 has a plurality of conductive segments 121, and a gap is formed between adjacent micro segment areas 120; wherein the line width of the conductive segment 12 is micron-level, the line length of the conductive segment 12 is millimeter-level, and the spacing between each conductive segment 121 of each micro segment area 120 is micron-level, so that the size of the micro electromagnetic element C is small; with the Figure 2As shown, in the second embodiment of the micro-electromagnetic element C of the present invention, the element layer 1 also includes positive conductive ends 13 and negative conductive ends 14 having the same number as the micro-segment areas 120, and each positive conductive end 13 and negative conductive end 14 of the element layer 1 is arranged on the front side of the substrate 11 of the element layer 1, and each micro-segment area 120 of the element layer 1 is arranged corresponding to a positive conductive end 13 and a negative conductive end 14 of the element layer 1; wherein the first ends of all the conductive segments 12 of each micro-segment area 120 are connected to the positive conductive end 13 corresponding to the micro-segment area 120, and the second ends of all the conductive segments 12 of each micro-segment area 120 are connected to the negative conductive end 14 corresponding to the micro-segment area 120; thus, in the second embodiment of the micro-electromagnetic element C of the present invention, the positive conductive end 13 and the negative conductive end 14 can facilitate the simultaneous access of each conductive segment 12 of the micro-segment area 120 to the current; similarly, the positive conductive end 13 and the negative conductive end 14 are respectively provided with a positive conductive hole 131 and a negative conductive hole 141 for accessing the external current.

This can also facilitate the partial conductive segment 12 of the micro-segment area 120 to access the external current through the positive conductive end 13 and the negative conductive end 14.

[0028] Cooperate Figures 3 to 5 As shown, in the third, fourth and fifth embodiments of the micro-electromagnetic element C of the present invention, the shapes of the various conductive segments 12 of the element layer 1 may be different, and the conductive segments 12 may be in a straight line segment structure, an oblique line segment structure, a folded line segment structure, a curved line segment structure, etc., and the various conductive segments 12 are not required to be parallel to each other. It should be noted that the shape and layout of the micro-electromagnetic element C of the present invention can be varied, as long as the conductive segments 12 of the micro-electromagnetic element C are subjected to forces in the same direction under the action of an external magnetic field when current is passed through them, so that the micro-electromagnetic element C can move under the action of an external magnetic field.

[0029] Cooperate Figure 6 As shown, in the sixth embodiment of the micro-electromagnetic element C of the present invention, each conductive segment 12 of the element layer 1 is in a straight segment structure, and each conductive segment 12 of the element layer 1 is parallel to each other. This arrangement can make the current direction of each conductive segment 12 of the element layer 1 the same, so that the micro-electromagnetic element C is subjected to a large force of the magnetic field, reducing unnecessary energy loss; each conductive segment 12 of the element layer 1 can be arranged at equal intervals, wherein the line width of the conductive segment 12 and the spacing between adjacent conductive segments 12 are in the micron level, and the line length of the conductive segment 12 can be in the millimeter level, so that the size of the micro-electromagnetic element C is small. Figure 6As shown, in the sixth embodiment of the micro-electromagnetic element C of the present invention, when the number of the element layers 1 is at least two, the first end of part or all of the conductive segments 12 of a certain element layer 1 is connected to the positive conductive end 13 provided on the substrate 11 of the element layer 1 adjacent to the element layer, and the second end of part or all of the conductive segments 12 of the element layer 1 is connected to the negative conductive end 14 provided on the substrate of the element layer adjacent to the element layer 13; the present invention is arranged in this way, which can facilitate the connection of the conductive segments 12 of a certain element layer 1 in series and / or in parallel, so that the conductive ends 12 of the element layer 1 can be connected to the current at the same time.

[0030] Cooperate Figure 7 As shown, in the seventh embodiment of the micro-electromagnetic element C of the present invention, the substrate 11 of at least one element layer 1 of the micro-electromagnetic element C is provided with a magnetic conductor 15. When the micro-electromagnetic element C is energized, the magnetic conductor 15 can reduce the magnetic resistance of the micro-electromagnetic element C and strengthen the magnetic lines of force of the magnetic field generated by the micro-electromagnetic element C, thereby increasing the strength of the magnetic field generated by the micro-electromagnetic element C.

[0031] In the present invention, when the number of the element layers 1 of the micro-electromagnetic element C is at least two, the positive conductive ends 13 and the negative conductive ends 14 of the adjacent element layers 1 can be connected to each other, so that the adjacent element layers 1 are connected in parallel or in series, so that the conductive segments 12 of each element layer 1 can be connected to the current at the same time. In the present invention, when the conductive segments 12 of each element layer 1 of the micro-electromagnetic element C are connected to the current, the micro-electromagnetic element C can interact with the external magnetic field, so that the micro-electromagnetic element C is subjected to the Ampere force and the micro-electromagnetic element C moves.

[0032] In the present invention, the micro-electromagnetic element C of the present invention includes at least one element layer 1 so that the micro-electromagnetic element C has a sheet-like structure as a whole. In this way, when the micro-electromagnetic element C of the present invention cooperates with the magnetic element, the magnetic element is located on the side of the micro-electromagnetic element C. In this way, when avoiding the interaction between the micro-electromagnetic element C and the magnetic element, only the gap setting in one direction needs to be considered, which helps to reduce the gap between the micro-electromagnetic element C and the magnetic element, thereby helping to increase the interaction force between the micro-electromagnetic element C and the magnetic element, and also helps to reduce the volume of the micro-electromagnetic element C. In addition, when the micro-electromagnetic element C of the present invention cooperates with the magnetic element, the magnetic element is located on the side of the micro-electromagnetic element, so that the installation constraint between the micro-electromagnetic element C and the magnetic element is small, so that the sizes of the micro-electromagnetic element C and the magnetic element can be independently increased, thereby helping to increase the interaction force between the micro-electromagnetic element C and the magnetic element.

[0033] Cooperate Figure 8As shown, the present invention also discloses an electromagnetic transducer T, which includes at least one magnetic element for generating a driving magnetic field and the above-mentioned micro-electromagnetic element C; wherein the number of the magnetic elements can be two, the two magnetic elements are divided into a first magnetic element T1 and a second magnetic element T2, and a driving magnetic field is generated between the first magnetic element T1 and the second magnetic element T2; the micro-electromagnetic element C is movably arranged between the first magnetic element T1 and the second magnetic element T2, so that the micro-electromagnetic element C is movably arranged in the driving magnetic field.

[0034] Cooperate Figure 8 As shown, when current is passed through each conductive segment 12 of the micro-electromagnetic element C, the micro-electromagnetic element C will interact with the driving magnetic field to make the micro-electromagnetic element C move. When a positive current or a reverse current is passed through each conductive segment 12 of the micro-electromagnetic element C, the driving magnetic field acts on the micro-electromagnetic element C, so that the micro-electromagnetic element C is subjected to an Ampere force perpendicular to the current direction and the magnetic field direction of the driving magnetic field, and the Ampere force drives the micro-electromagnetic element C to move. The Ampere force satisfies the formula: F=∑B·I·L; wherein F is the Ampere force, B is the magnetic field strength of the driving magnetic field, I is the current of the conductive segment 12, and L is the line length of the conductive segment 12; wherein when the current direction of the conductive segment 12 changes, the direction of the Ampere force also changes accordingly, so that when the current direction of the conductive segment 12 changes repeatedly in the opposite direction (such as the current of the conductive segment 12 is alternating current), the micro-electromagnetic element C performs reciprocating motion. In the present invention, the current direction of the conductive segment 12 is arranged to intersect with the magnetic field direction of the driving magnetic field, so that the micro-electromagnetic element C moves under the action of the driving magnetic field; preferably, the current direction of each conductive segment 12 of the micro-electromagnetic element C is the same, and the current direction of each conductive segment 12 of the micro-electromagnetic element C is arranged perpendicular to the magnetic field direction of the driving magnetic field, so that the ampere force on the micro-electromagnetic element C is maximized, so that the interaction force between the micro-electromagnetic element C and the magnetic element is large. The first magnetic element T1 and the second magnetic element T2 can be arranged relative to each other so that the driving magnetic field is a parallel magnetic field, which also helps to increase the interaction force between the micro-electromagnetic element C and the magnetic element.

[0035] Cooperate Figure 8 As shown, the electromagnetic transducer T of the present invention may also include a shell T3, which is used to carry the first magnetic element T1, the second magnetic element T2 and the micro-electromagnetic element C; wherein the first magnetic element T1 and the second magnetic element T2 are respectively arranged on opposite sides of the shell T3, that is, the magnetic element of the electromagnetic transducer T of the present invention is arranged on the inner side of the shell T3, and the micro-electromagnetic element C is movably arranged in the shell T3. The material of the shell T3 can be a magnetic conductive material, so that the degree of magnetization in the shell T3 can be adjusted by selecting magnetic conductive materials with different magnetic permeabilities, thereby helping to increase the interaction force between the micro-electromagnetic element C and the magnetic element.

[0036] The present invention also discloses an electronic device, which includes the electromagnetic transducer T mentioned above; Fig. 9 As shown, the electronic device may be a micro speaker S, which specifically includes a diaphragm S1 and the above-mentioned electromagnetic transducer T, wherein the diaphragm S1 is combined with the micro-electromagnetic element C of the electromagnetic transducer T, and when the micro-electromagnetic element C moves, it will drive the diaphragm S1 to move, thereby producing sound; wherein the magnitude and direction of the vibration of the diaphragm S1 can be controlled by controlling the magnitude and direction of the current passing through the conductive segment 12 of the micro-electromagnetic element C, thereby changing the frequency and volume of the sound. It should be noted that the electronic device may also be a micro motor, that is, the electromagnetic transducer T of the present invention may also be applied to a micro motor, which may be a linear motor or a rotor motor.
