[0023] The present invention proposes a linear micro-segment element 10. The basic structure of the linear micro-segment element 10 and the transducer component formed based on the linear micro-segment element 10 can be referred to in the disclosure of Figures 1 to 8 In the illustrated example, the linear micro-segment element 10 can be formed on a substrate 100 by plating or metallization process, or lithography and etching process to form parallel metal segments 101 with consistent directions, so as to realize miniaturized linear micro-segment element 10, which replaces the conventional electromagnetic coil for forming electromagnetic field by coil. The transducer component mainly means an element for converting electrical energy into kinetic energy, and current is introduced into the linear micro-segment 101 in the transducer component to interact with the magnetic field of the magnetic element, thereby converting electrical energy into kinetic energy to drive the diaphragm 20, and the movement of the diaphragm forms sound waves to generate audio signals.

[0024] Cooperate Figure 1As shown, in the first embodiment of the linear micro-segment element of the present invention, there is a gap between adjacent metal segments 101 of the linear micro-coil element 10, which is called a segment gap 102. The segment gap 102 can be formed by etching away the portion of the substrate 100 through an etching process. The material of the substrate 100 can preferably be silicon, ceramic, glass, sapphire, laser direct molding plastic, germanium chip, gallium arsenide, indium phosphide, gallium nitride, silicon carbide, zinc selenide, glass fiber, epoxy resin, phenolic resin, polyimide (PI), modified polyimide (MPI), liquid crystal polymer (LCP) polymer, BT (Bismaleimide Triacine), ABF (Ajinomoto Build-up Film), bakelite, plastic or modified polyimide; the material of the substrate 100 includes but is not limited to the above semiconductor, IC substrate or PCB related materials. The metal line segments 101 on the substrate 100 may be arranged in blocks, such as Figure 1 , three blocks are provided on the substrate 100, each block is called a micro-segment area 1000, each micro-segment area 1000 has various metal segments 101, there is a gap between adjacent micro-segment areas 1000, and either end of each metal segment 101 is connected to a power connection part for electrically connecting to the positive or negative pole of a power source; Figure 1 As shown, the starting position of each metal line segment 101 forms the first electrode of the linear micro-line segment element 10, and the ending position of each metal line segment 102 forms the second electrode of the linear micro-line segment element 10. A first power connection portion 103 and a second power connection portion 104 are respectively formed at both ends of the micro-line segment region 1000 formed by multiple metal line segments 101. The first power connection portion 103 of the micro-line segment region 1000 is electrically connected to each first electrode of each metal line segment 101 of the micro-line segment region 1000, and the first electrode can be the negative electrode of the metal line segment 101. The second power connection portion 104 of the micro-line segment region 1000 is electrically connected to each second electrode of each metal line segment 101 of the micro-line segment region 1000, and the second electrode can be the positive electrode of the metal line segment 101. After the linear micro-segment element 10 is connected to a power source and energized, the currents flowing through the metal wire segments 101 of the linear micro-segment element 10 have the same direction of flow. At this time, the currents flowing through the metal wire segments 101 of the linear micro-coil element 10 interact with the magnetic field of the magnetic element to generate a force of interaction between the magnetic field and the current, thereby realizing a transducer component, thereby causing the linear micro-segment element 10 to drive the diaphragm 20 connected thereto to vibrate, and then the vibration of the diaphragm 20 is converted into sound wave energy, which causes the air to vibrate and make sound.

[0025] In the first embodiment of the linear micro-segment element of the present invention, the material, line width, length, gap between adjacent metal segments or the number and area of ​​micro-segment regions 100 of the metal segments 101 in the linear micro-segment element 10 are all parameters that determine the impedance value of the entire linear micro-segment element 10. Therefore, when designing this linear micro-coil element, it is necessary to know the impedance and the magnetic field conditions that are desired to be formed. For example, in the first embodiment of the linear micro-segment element of the present invention, when designing the metal wire segments 101 of each linear structure that is parallel and oriented in the same direction, one of the semiconductor processes (such as photolithography), IC substrate processes, and PCB processes (such as subtractive (tenting) processes, SAP (Semi-Additive Processes) processes, and MSAP (Modified Semi-Additive Processes) processes) can be used to form metal wire segments 101 with maximized lengths in the same direction on a limited substrate 10 area, and the segment gaps 102 between adjacent metal wire segments 101 can be minimized. The purpose is to allow the metal wire segments 1001 that can form a magnetic field when energized to have the largest area and be able to withstand higher currents. In addition, the two ends of the metal wire segments 101 in the linear micro-segment element 10 are respectively connected to the power connection parts, mainly to provide a consistent current direction after the current is input to each metal wire segment 101. The size implementation example of a linear micro-segment element 10 is listed, wherein the length size range of each metal segment 101 is in the millimeter level (mm), thereby forming a linear micro-segment element 10 with an overall size level of square millimeters, and the width size of the internal metal segment 101 and the spacing between adjacent metal segments 101 are in the micrometer or nanometer level (μm / nm). Specifically, the present invention can use one of silicon wafers, germanium wafers, gallium nitride, second-generation semiconductors and third-generation semiconductors as the substrate 100, and then process the metal segment 101 on the substrate 100 through a chemical vapor deposition process, thereby obtaining the linear micro-segment element 10. The present invention can also use one of PCB, IC substrate and glass substrate as the substrate 100, and then process the metal segment 101 on the substrate 100 through one of an MSAP process, a SAP process, a thick copper process and a subtractive process, thereby obtaining the linear micro-segment element 10. The thickness of the metal line segment 101 is 0.0001-10 micrometers and the ratio of the line width / line spacing of the metal line segment 101 is greater than 0.3.

[0026] Cooperate Figure 2As shown, in the second embodiment of the linear micro-segment element of the present invention, a linear micro-segment element 10 is formed on a substrate 100. The linear micro-segment element 101 has a plurality of parallel metal segments 101 with a small spacing, and each metal segment 101 is integrated into a micro-segment region 1000. When manufacturing the linear micro-segment element 10, the semiconductor process can be used to make adjacent metal segments 101 have a minimized segment gap 102. Similarly, the starting position of each metal segment 101 forms the first electrode of the linear micro-segment element 10, and the ending position of each metal segment 101 forms the second electrode of the linear micro-segment element 10. The two ends of the micro-segment region 1000 respectively form a first power connection portion 103 and a second power connection portion 104. The first power connection portion 103 of the micro-segment region 1000 is electrically connected to the micro-segment region 1000. Each first electrode of each metal wire segment 101 of the micro-segment area 1000, the first electrode can be the negative electrode of the metal wire segment 101, the second power connection part 104 of the micro-segment area 1000 is electrically connected to each second electrode of each metal wire segment 101 of the micro-segment area 1000, and the second electrode can be the negative electrode of the metal wire segment 101; the present invention electrically connects a power source (not shown) through the first power connection part 103 and the second power connection part 104, so that the current flowing through each metal wire segment 101 can interact with the magnetic field of the magnetic element.

[0027] In the first and second embodiments of the linear micro-segment element of the present invention, the design of the linear micro-segment element 10 can determine the total length, line width, line spacing between adjacent metal segments 101, length of each metal segment 101 and / or material of the metal segment 101 according to the impedance value, magnetic field or size requirements. In particular, the specifications of the linear micro-segment element 10 can adjust the parameters such as impedance, line width, line length according to actual needs to provide a customized element. The first power connection portion 103 and the second power connection portion 104 can be provided with guide holes for connection with a power source.

[0028] Figure 3 is a schematic diagram of the first design principle of the energy conversion component of the present invention, Figure 3The internal structure of the transducer assembly covered by a shell 30 is shown. In the first design of the transducer assembly of the present invention, the main components of the transducer assembly include at least one magnetic element, preferably two magnetic elements, arranged inside the shell 30. The two magnetic elements are divided into a first magnetic element 401 and a second magnetic element 402. For example, at least one of the first magnetic element 401 and the second magnetic element 402 can be a magnet, or other magnetic objects that can form a stable magnetic force, and the first magnetic element 401 and the second magnetic element 402 can be fixed on the inner walls of two opposite sides of the shell 30, respectively. When the first magnetic element 401 and the second magnetic element 402 are arranged, the relative magnetism of the first magnetic element 401 and the second magnetic element 402 should be N pole and S pole, respectively, so that the first magnetic element 401 and the second magnetic element 402 generate a magnetic force that attracts each other, so that the first magnetic element 401 and the second magnetic element 402 can form a first magnetic force line 403 from N pole to S pole inside the shell 30 of the transducer assembly.

[0029] In the first design of the transducer assembly of the present invention, the shell 30 can be preferably made of a magnetic conductive material, that is, the transducer assembly is covered with a magnetic conductive member. According to the requirements, the magnetic conductive materials with different magnetic permeabilities can be used to adjust (or strengthen) the degree of magnetization in the shell 30, and the main function is to guide the magnetic path direction of the magnetic field formed by at least one magnetic element in the transducer assembly and strengthen the magnetic force. The transducer assembly in the shell 30 also includes a linear micro-segment element 10, and the linear micro-segment element 10 is elastically connected rather than fixedly arranged in the shell 30, and a power supply (not shown in the figure) supplies current to this linear micro-segment element 10. For example, taking the first embodiment of the linear micro-segment element of the present invention as an example, the current can be input from the first power connection part 103 at one end of the micro-segment area 1000, and after passing through a plurality of metal segments 101, it is output from the second power connection part 104 at the other end of the micro-segment area 1000, that is, the current direction of each metal segment 101 in the micro-segment area 1000 is the same. In this way, the current direction (I) or the reverse current direction (I') passing through the linear micro-segment element 10 is acted upon by the magnetic field direction (B, i.e., the direction of the first magnetic force line 403) formed between the first magnetic element 401 and the second magnetic element 402, and thus generates a force perpendicular to the current direction (I, I') and the magnetic field direction (B), which drives the elastically connected linear micro-segment element 10 (and its substrate or base) to move in the motion direction (F, F') shown in the figure. The magnetic field direction B and the current direction (I, I') act to form a force (motion direction F, F') that drives the linear micro-segment element 10, which can be expressed by equation 1 (F=q*V*B"). The first design of the transducer assembly of the present invention is conducive to reducing the distance between the linear micro-segment element 10 and the magnetic element, and is more conducive to further strengthening the strength of the magnetic field passing through the linear micro-segment element 10.

[0030] Figure 4 is a schematic diagram of the second design principle of the energy conversion component of the present invention, Figure 4 The structure of the display transducer assembly inside the housing 30. In the second design of the transducer assembly of the present invention, only one magnetic element is provided on one side of the linear micro-segment element 10. The magnetic element is the first magnetic element 401. The first magnetic element 401 can also be a magnet. The N pole and the S pole of the first magnetic element 401 can still form a stable magnetic field (such as Figure 4 The second magnetic force lines 404 shown in the figure), the magnetic force formed inside the housing 30 can still react with the current passing through the metal wire segment 101 of the linear micro-segment element 10 to form a force to drive the linear micro-segment element 10 to move. The second design of the transducer assembly of the present invention only has one magnetic element, with fewer parts, which is conducive to improving production efficiency and reducing costs.

[0031] Figure 5 The third design principle of the energy conversion component of the present invention is shown in FIG. Figure 1 , Figure 6 The third design principle of the energy conversion component of the present invention is shown in FIG. Figure 2 In the third design of the transducer assembly of the present invention, the transducer assembly includes a first magnetic element 401 and a second magnetic element 402 arranged opposite to each other, and there is at least one linear micro-segment element 10 between the first magnetic element 401 and the second magnetic element 402 arranged opposite to each other. The first magnetic element 401 and the second magnetic element 402 can also be magnets. However, unlike the first design of the transducer assembly of the present invention, the magnetism of the first magnetic element 401 and the second magnetic element 402 in the third design of the transducer assembly of the present invention generates a mutually repelling magnetic force (such as Figure 6 The third magnetic force line 405, the fourth magnetic force line 406, the fifth magnetic force line 407 and the sixth magnetic force line 408 are shown in the figure). In the third design of the transducer assembly of the present invention, the linear micro-segment element 10 is arranged at the gathering place of the repulsive magnetic force formed between the first magnetic element 401 and the second magnetic element 402, so that the mutually repulsive magnetic force can pass through the linear micro-segment element 10. A magnetic conductive element 50 can be arranged between the first magnetic element 401 and the second magnetic element 402, and the magnetic conductive element 50 is used to guide the mutually repulsive magnetic force to pass through the linear micro-segment element 10; in addition, the shell 30 can be made of a magnetic conductive material, and the shell 30 forms a magnetic conductive wall 301 for guiding the mutually repulsive magnetic force. The interaction between the magnetic force and the current flowing through each linear micro-segment element 10 can form a force in one direction, which is converted into driving the linear micro-segment element 10 to move. When each linear micro-segment element 10 is combined with the diaphragm 20, it can drive the diaphragm 20 to vibrate. The second design of the transducer assembly of the present invention can improve the interaction between the linear micro-segment element 10 and the magnetic field.

[0032] According to several designs of the above-mentioned transducer components, the linear micro-segment element 10 is provided with at least one magnetic element on at least one side thereof, and the magnetic element is used to form a magnetic field passing through the linear micro-segment element. The energized linear micro-segment element 10 interacts with the magnetic field of the magnetic element to form a driving force for driving the linear micro-segment element 10 to move, wherein the formed driving force can be expressed by equation 1 (F=q*V*B"). Wherein F is the force of the interaction between the magnetic field and the current, and this force is the force that drives the linear micro-segment element 10 to move in one direction, q represents the charge, and the charge q moves at a speed v to form a current, such as the current (I, I') in the above-mentioned figure, and B is the magnetic field strength, that is, the magnetic field formed by the magnetic elements provided on one side or both sides of the linear micro-segment element 10 in the above-mentioned embodiment; in this way, a force F that drives the linear micro-segment element 10 is formed. When the current direction (I, I') can be changed repeatedly in opposite directions, such as alternating current, which can drive the linear micro-segment element 10 to move back and forth in one direction repeatedly, that is, to move back and forth in two opposite movement directions F, F'.

[0033] The present invention Figure 7 The first matching mode of the linear micro-segment element and the diaphragm of the present invention is shown, wherein the linear micro-segment element 10 and the diaphragm 20 are connected at an approximately vertical angle, and the movement of the linear micro-segment element 10 can drive the diaphragm 20 to vibrate. The first matching mode of the linear micro-segment element and the diaphragm of the present invention can be adapted to the first design, the second design and the third design of the transducer assembly of the present invention.

[0034] The present invention Figure 8The second matching mode of the linear micro-segment element and the diaphragm of the present invention is shown, wherein the linear micro-segment element 10 is matched with at least one diaphragm 20, specifically, the linear micro-segment element 10 is matched with two diaphragms 20 arranged opposite to each other, so that when the linear micro-segment element 10 with current interacts with the magnetic field therein to generate movement, especially repeated movement, the two diaphragms 20 can jointly form a shock wave of the same frequency; the external control circuit can control the current intensity passing through the linear micro-segment element 10 to determine the frequency of the shock wave, thereby emitting sound. The diaphragm 20 can be made of conductive material so that the diaphragm itself can be conductive; or the diaphragm 20 is provided with a conductive circuit; the diaphragm 20 is connected to the linear micro-segment element 10 with a conductive adhesive 60. The diaphragm 20 can be electrically connected to the power connection parts of the plurality of metal segments 101 of the linear micro-segment element 10 through the conductive adhesive 60 and electrically conduct with the metal segments 101 of the linear micro-segment element 10. In this way, the multiple diaphragms 20 can connect the current generated by the power supply to the multiple power connection parts on the linear micro-segment element 10 through the conductive adhesive 60. The second matching mode of the linear micro-segment element and the diaphragm of the present invention can be adapted to the first design, the second design and the third design of the transducer assembly of the present invention.

[0035] One of the methods of the present invention for energizing the plurality of metal segments 101 on the linear micro-segment element 10 can be referred to Fig. 9 The schematic diagram shown is of a linear micro-segment element connected to a power source using a flexible circuit board; wherein, the power connection parts connected at both ends of each metal segment 101 of the linear micro-segment element 10 are connected to the flexible circuit board 70 using a connector, so that the power connection parts connected at both ends of the metal segment 101 are connected to the power source through this flexible circuit board 70; this facilitates the connection of an external power source.

[0036] Cooperate Fig.10As shown, the electrical connection parts at both ends of the metal wire segment 101 of the linear micro-segment element 10 form electrode pads 80, which are electrically connected to an external power source; the electrode pads 80 can be connected to the power source through welding wires. The shell 30 can be provided with a first electrode area 302 and a second electrode area 303, and the first electrode area 302 and the second electrode area 303 can be formed by filling a groove on the shell with a conductive material, and the electrical connection parts at both ends of the multiple parallel metal wire segments on the linear micro-segment element 10 are provided with electrode pads 80, and the two electrode pads 80 are respectively connected to the first electrode area 302 and the second electrode area 303 by a first welding wire 811 and a second welding wire 812; in this way, at least one electrode area provided on the shell can be connected to the power source by welding wires. It is worth mentioning here that the first welding wire 811 and the second welding wire 812 themselves can be conductive materials and can be connected to the first electrode area 302 and the second electrode area 303 by welding. The welding method can facilitate efficient automated production; the first welding wire 811 and the second welding wire 812 are also connected to the first electrode area 302 and the second electrode area 303 by welding through welding materials.

[0037] Furthermore, in the present invention, the diaphragm 20 can be a magnetic conductive member or a membrane made of a conductive material. The magnetic conductive member implemented by the diaphragm 20 can guide the magnetic path direction of the magnetic field formed by the magnetic element in the transducer assembly and strengthen the magnetic force; if the diaphragm is made of a conductive material, the diaphragm 20 can be used to electrically connect to the positive or negative pole of the power supply to obtain the electrical connection method shown in the above embodiment.

[0038] According to the above description, when the direction of the current supplied to the linear micro-segment element 10 is repeatedly changed in the opposite direction, that is, the linear micro-segment element 10 is driven to move back and forth repeatedly in the direction, while driving one or more diaphragms 20 to generate shock waves. The transducer component formed thereby is arranged in the device to realize headphones or hearing aids.

[0039] One of the main purposes of the present invention is to replace the traditional magnetic element such as the coil in the existing electronic sound-generating device with a transducer component formed by a straight micro-segment 10.

The implementation can be designed with multiple cavities. The cavity shown in this example is provided with a first magnetic element 401 and a second magnetic element 402 which can be implemented as magnets, and in particular, the north pole (N pole) and the south pole (S pole) of the first magnetic element 401 and the second magnetic element 402 in this example are in the same direction, and a magnetic field with the same direction is also formed inside the shell 30. For reference, Fig.12The arrows indicate the first magnetic field direction 117 and the second magnetic field direction 118. A diaphragm 20 is disposed in the cavity of the housing 30. The diaphragm 20 is elastically connected to the housing 30 via a suspension edge. A linear micro-segment element 10 is disposed on the diaphragm 20 through which current can pass. Fig.12 The current direction 119 of the current passing through the plurality of metal segments on the linear micro-segment element 10 can interact with the first magnetic field direction 117 and the second magnetic field direction 118 respectively formed by the first magnetic element 401 and the second magnetic element 402 in the magnetic shell 30, thereby generating a force driving the linear micro-segment element 10 to move in one direction and driving the diaphragm 20 to move, forming a Fig.12 The vibration direction 115 of the up and down movement is shown.

[0041] Cooperate Fig.13 and Fig.14 As shown, in the second embodiment of the electronic sound-generating device of the present invention, a first magnetic element 401, a second magnetic element 402 and a third magnetic element 409 are arranged in the housing 30 of the magnetic conductive material, and the magnetic field superposition effect is generated by designing the north pole (N) and south pole (S) directions of the multiple magnetic elements. The magnetic field formed by the first magnetic element 401, the second magnetic element 402 and the third magnetic element 409 in this example can be referred to Fig.14 The direction of the magnetic field is shown as 128. A diaphragm 20 is also provided in the housing 30, and can be elastically connected to the housing 30 through the suspension edge. A linear micro-segment element 10 is provided on the diaphragm 20. The current direction of the current flowing through the metal segment 101 on the linear micro-segment element 10 is as shown in FIG. Fig.14 The current direction 119 is shown. The current interacts with the magnetic field formed by the first magnetic element 401, the second magnetic element 402 and the third magnetic element 409 to generate a force that drives the linear micro-segment element 10 on the diaphragm 20 to move, and the linear micro-segment element 10 drives the diaphragm 20 to vibrate.

[0042] In the first and second embodiments of the electronic sound-generating device of the present invention, a side with a larger area of ​​the linear micro-segment element 10 is connected to the diaphragm 20, and the effective area between the linear micro-segment element 10 and the diaphragm 20 is conducive to the smooth output of force and sound signals.

[0043] In summary, the transducer assembly formed by the linear micro-segment element 10 described in the above embodiment can be miniaturized and lightweight, and can form a plurality of single-body loudspeaker devices in a specific space.
