Description

Technical Field

[0001] This application relates to the technical field of loudspeakers, and particularly to a loudspeaker and electronic device. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals. A loudspeaker may include two transducers superimposed in the direction of movement of the moving coil. The two transducers can be mounted on the same mounting frame and can be symmetrically arranged about the mounting frame. The transducers can effectively reduce vibration and improve the external sound output by utilizing the principle of force cancellation.

[0003] However, the transducer mechanism in the speaker of the aforementioned related technologies has a small amplitude, which affects the speaker's external playback performance. Utility Model Content

[0004] This application provides a loudspeaker and electronic device that can increase the amplitude of the transducer mechanism in the loudspeaker and improve the loudspeaker's external playback performance.

[0005] A first aspect of this application provides a loudspeaker, comprising:

[0006] The mounting frame includes a first mounting groove and a second mounting groove disposed opposite to each other along a first direction, the bottoms of the first mounting groove and the second mounting groove are connected, and the inner bottom wall of the first mounting groove has a first recess.

[0007] A first transducer mechanism is disposed within the first mounting slot, and the first transducer mechanism includes:

[0008] The first magnetic circuit unit has a first magnetic gap disposed corresponding to the first recess;

[0009] A first moving coil is disposed in the first magnetic gap, and at least a portion of the first moving coil moves along the first direction into the first recess;

[0010] The second transducer is located in the second mounting slot.

[0011] The loudspeaker provided in this application embodiment, by setting a first recess on the bottom of the first mounting groove of the mounting frame at a position corresponding to the first magnetic gap, enables the first moving coil to not only move in the first magnetic gap along the first direction, but also enables at least a portion of the first moving coil to move into the first recess, thereby realizing the first moving coil to reciprocate in the first direction in the first recess and the first magnetic gap. Since the dimensions of the first transducer mechanism and the second transducer mechanism along the first direction remain unchanged, the distance of the first moving coil to reciprocate in the first direction is increased, thereby increasing the amplitude of the first transducer mechanism without changing the overall thickness of the loudspeaker, improving the amplitude of the loudspeaker, and thus improving the external playback performance of the loudspeaker.

[0012] In one possible implementation, the first magnetic circuit unit further includes:

[0013] The first central magnet is disposed at the bottom of the first mounting groove, and the first recess surrounds the outer periphery of the first central magnet.

[0014] A first side magnet is disposed around the outer edge of the first recess, and a first magnetic gap is formed between the first side magnet and the first central magnet.

[0015] The first magnetic yoke is disposed on the side of the first central magnet facing away from the second transducer mechanism;

[0016] The first magnetic yoke covers the first magnetic gap, and the first magnetic yoke is connected to the first side magnetic field.

[0017] The first central magnet can be a permanent magnet structure. The first central magnet, the first yoke, and the first side magnet can form a complete magnetic circuit, enabling the first transducer to form an internal magnet transducer. The first central magnet, as a permanent magnet, is wrapped by the first side magnet. The magnetic circuit of the first magnetic circuit unit contracts centripetally, resulting in a smaller volume compared to an external magnet transducer, which helps to reduce the volume of the first transducer and, consequently, the volume of the loudspeaker.

[0018] In one possible implementation, the bottom wall of the first recess is provided with a first through hole connecting the first mounting groove and the second mounting groove;

[0019] The first through hole is correspondingly provided with the first moving coil, and at least a portion of the first moving coil can move into the first through hole along the first direction.

[0020] In this way, the first moving coil can be moved further into the first through hole along the first direction, thereby further increasing the moving distance of the first moving coil in the first direction and further increasing the amplitude of the first transducer mechanism.

[0021] In one possible implementation, the first magnetic yoke has a third recess on the side facing the first moving coil, and the third recess is in communication with the first magnetic gap.

[0022] This avoids the first magnetic yoke from protruding from the first mounting groove, reduces the thickness of the speaker along the first direction, and reduces the probability of the outer periphery of the first magnetic yoke being hit, thereby improving the durability and service life of the first magnetic yoke.

[0023] In one possible implementation, the first transducer mechanism further includes a first vibration component;

[0024] The first vibration component is disposed around the outer periphery of the first magnetic circuit unit, and one side of the first vibration component is connected to the first magnetic circuit unit, while the other side of the first vibration component is connected to the inner sidewall of the first mounting groove.

[0025] This avoids increasing the thickness of the first transducer mechanism along the first direction by the first vibration component, thereby avoiding an increase in the thickness of the loudspeaker along the first direction and helping to reduce the space occupied by the loudspeaker in the thickness direction.

[0026] In one possible implementation, the first vibration component is disposed away from the inner bottom wall of the first mounting groove;

[0027] Alternatively, the first vibration component may be positioned close to the inner bottom wall of the first mounting groove.

[0028] In one possible implementation, the first vibration component includes:

[0029] A first diaphragm is disposed around the outer periphery of the first magnetic circuit unit. One side of the first diaphragm is connected to the mounting frame, and the other side is connected to the first magnetic circuit unit.

[0030] A first frame is disposed around the outer periphery of the first magnetic circuit unit. One side of the first frame is connected to the first moving coil, and the other side is connected to the first diaphragm.

[0031] A first transmission component is disposed on the first diaphragm and is connected to the first frame.

[0032] The first flexible circuit board is electrically connected to the first moving coil.

[0033] By setting the first flexible circuit board, current can be transmitted to the first moving coil. The flexible circuit board has good flexibility and can be bent in any shape, which helps to adapt to different installation spaces. In addition, the thickness of the first flexible circuit board is relatively thin, which can reduce the occupancy rate of the speaker's internal space.

[0034] Furthermore, the first frame can transmit the vibration of the first moving coil to the first transmission component, so that the first frame drives the first transmission component to reciprocate along the first direction. The first transmission component further drives the first diaphragm to reciprocate along the first direction. The structural strength of the first transmission component is greater than that of the first diaphragm, and the ability of the first transmission component to overcome air resistance and vibrate along the first direction is greater than that of the first diaphragm. Therefore, by setting the first transmission component, it is helpful to drive the first diaphragm to reciprocate along the first direction, thereby ensuring the vibration effect of the first diaphragm.

[0035] The first transmission component can be disposed at the middle part of the first diaphragm along the side wall of the first mounting groove to the first magnetic circuit unit, thereby making the vibration amplitude distribution on the first diaphragm more uniform and avoiding audio distortion.

[0036] In one possible implementation, the first vibration component further includes a first adjustment diaphragm;

[0037] One end of the first adjustment membrane is connected to the inner wall of the first mounting groove, and the other end is connected to the first flexible circuit board, which is connected to the first skeleton.

[0038] In this way, by setting the first adjustment diaphragm, the polarization and mixing of the first diaphragm can be suppressed, the vibration effect of the first transducer mechanism can be improved, and thus the external sound output of the speaker can be improved.

[0039] In one possible implementation, the inner bottom wall of the second mounting groove has a second recess corresponding to the first recess;

[0040] The second transducer includes:

[0041] The second magnetic circuit unit has a second magnetic gap disposed corresponding to the second recess;

[0042] A second moving coil is disposed in the second magnetic gap, and at least a portion of the second moving coil moves along the first direction into the second recess.

[0043] The loudspeaker has a second recess on the bottom of the second mounting groove of the mounting frame, corresponding to the second magnetic gap. This allows the second moving coil to not only move in the second magnetic gap along the first direction, but also allows at least a portion of the second moving coil to move into the second recess. This enables the second moving coil to reciprocate in the second recess and the second magnetic gap along the first direction. Since the dimensions of the second transducer mechanism and the second transducer mechanism along the first direction remain unchanged, the distance of the second moving coil reciprocating in the first direction is increased. This increases the amplitude of the second transducer mechanism without changing the overall thickness of the loudspeaker, thereby improving the loudspeaker's external sounding performance.

[0044] In one possible implementation, the second magnetic circuit unit further includes:

[0045] The second central magnet is disposed at the bottom of the second mounting groove, and the second recess surrounds the outer periphery of the second central magnet.

[0046] A second side magnet is disposed around the outer edge of the second recess, and a second magnetic gap is formed between the second side magnet and the second central magnet.

[0047] The second magnetic yoke is disposed on the side of the second central magnet facing away from the first transducer mechanism;

[0048] The second magnetic yoke covers the second magnetic gap, and the second magnetic yoke is connected to the second side magnet.

[0049] The second central magnet can be a permanent magnet structure. The second central magnet, the second yoke, and the second side magnet can form a complete magnetic circuit and enable the second transducer to form an internal magnet transducer. The second central magnet, as a permanent magnet, is wrapped by the second side magnet. The magnetic circuit of the second magnetic circuit unit contracts centripetally, making it smaller in volume than the external magnet transducer, which helps to reduce the volume of the second transducer and thus helps to reduce the volume of the loudspeaker.

[0050] In one possible implementation, the bottom wall of the second recess is provided with a second through hole connecting the first mounting groove and the second mounting groove;

[0051] The second through hole is provided corresponding to the second moving coil, and at least a portion of the second moving coil can move into the second through hole along the first direction.

[0052] In this way, the second moving coil can be moved further into the second through hole along the first direction, thereby further increasing the moving distance of the second moving coil in the first direction and further increasing the amplitude of the second transducer mechanism.

[0053] In one possible implementation, the second magnetic yoke has a fourth recess on the side facing the two moving coils, and the fourth recess is in communication with the first magnetic gap.

[0054] In this way, a portion of the second moving coil structure can be moved along the first direction into the fourth recess, thereby increasing the movement amplitude of the second moving coil along the first direction, and thus improving the amplitude of the second transducer mechanism and the external playback performance of the loudspeaker.

[0055] In one possible implementation, the installation framework includes:

[0056] Outer frame;

[0057] The mounting plate is disposed within the outer frame and is used to divide the outer frame into a first mounting groove and a second mounting groove. The mounting plate has a first surface and a second surface opposite to each other along the first direction. The first surface is the inner bottom wall of the first mounting groove, and the second surface is the inner bottom wall of the second mounting groove.

[0058] In this way, the structure of the outer frame and mounting plate is relatively simple and the number of parts is relatively small, which can simplify the manufacturing process of the mounting frame and improve the assembly efficiency of the mounting frame.

[0059] In some embodiments, the mounting plate may be detachably connected to the outer frame, which facilitates the separate removal and maintenance of both the mounting plate and the outer frame. Alternatively, the mounting plate and the outer frame may be an integral structure.

[0060] In one possible implementation, the second transducer mechanism further includes a second vibration component;

[0061] The second vibration component is disposed around the outer periphery of the second magnetic circuit unit, and one side of the second vibration component is connected to the second magnetic circuit unit, while the other side of the second vibration component is connected to the inner wall of the second mounting groove.

[0062] This avoids increasing the thickness of the second transducer mechanism along the first direction by the second vibration component, thereby avoiding an increase in the thickness of the speaker along the first direction and helping to reduce the space occupied by the speaker in the thickness direction.

[0063] In one possible implementation, the second vibration component is disposed away from the inner bottom wall of the second mounting groove;

[0064] Alternatively, the second vibration component may be positioned close to the inner bottom wall of the second mounting groove.

[0065] The speaker can achieve a "back-to-back" arrangement of the first and second transducer mechanisms. This "back-to-back" arrangement allows the two transducer mechanisms to move in opposite directions, significantly reducing the vibration energy transmitted to the device casing through inertial force cancellation, thereby reducing keyboard resonance noise and improving touch stability.

[0066] In one possible implementation, the second vibration component includes:

[0067] The second diaphragm is disposed around the outer periphery of the second magnetic circuit unit. One side of the second diaphragm is connected to the mounting frame, and the other side is connected to the second magnetic circuit unit.

[0068] The second frame is arranged around the outer periphery of the second magnetic circuit unit. One side of the second frame is connected to the second moving coil, and the other side is connected to the second diaphragm.

[0069] The second transmission component is disposed on the second diaphragm and is connected to the second frame.

[0070] The second flexible circuit board is electrically connected to the second moving coil.

[0071] By setting a second flexible circuit board, current can be delivered to the second moving coil. The flexible circuit board has good flexibility and can be bent in any shape, which helps to adapt to different installation spaces. In addition, the thickness of the second flexible circuit board is relatively thin, which can reduce the occupancy rate of the speaker's internal space.

[0072] Furthermore, the second frame can transmit the vibration of the second moving coil to the second transmission component, so that the second frame drives the second transmission component to reciprocate along the second direction. The second transmission component further drives the second diaphragm to reciprocate along the second direction. The structural strength of the second transmission component is greater than that of the second diaphragm, and the ability of the second transmission component to overcome air resistance and vibrate along the second direction is greater than that of the second diaphragm. Therefore, by setting the second transmission component, it is helpful to drive the second diaphragm to reciprocate along the second direction, thereby ensuring the vibration effect of the second diaphragm.

[0073] The second transmission component can be disposed at the middle part of the second diaphragm along the side wall of the second mounting groove to the second magnetic circuit unit, thereby making the vibration amplitude distribution on the second diaphragm more uniform and avoiding audio distortion.

[0074] In one possible implementation, the second vibration component further includes a second adjustment diaphragm;

[0075] One end of the second adjustment membrane is connected to the inner wall of the second mounting groove, and the other end is connected to the second flexible circuit board, which is connected to the second skeleton.

[0076] In this way, by setting a second adjustment diaphragm, the polarization and mixing of the second diaphragm can be suppressed, the vibration effect of the second transducer mechanism can be improved, and thus the external sound output of the speaker can be improved.

[0077] A second aspect of this application provides an electronic device that includes a speaker as described above. Attached Figure Description

[0099] The transducer mechanism in the loudspeaker of the related technology has a small amplitude, which affects the loudspeaker's external sound output performance. The reason for this problem is that, on the one hand, the existing technology's vertical arrangement of two transducer mechanisms will significantly increase the thickness of the loudspeaker. In order to reduce the impact of the loudspeaker on the overall thickness of the electronic device, the thickness of the two transducer mechanisms needs to be reduced to make the loudspeaker thinner overall. As the thickness of the transducer mechanism is reduced, the amplitude of the transducer mechanism in the loudspeaker becomes smaller, which affects the loudspeaker's external sound output performance.

[0100] To address the aforementioned technical problems, this application provides a loudspeaker and an electronic device. The loudspeaker features a first recess on the bottom of a first mounting groove of a mounting frame, corresponding to a first magnetic gap. This allows the first moving coil to not only move along a first direction within the first magnetic gap but also to move at least a portion of the first moving coil into the first recess. This enables the first moving coil to reciprocate along the first direction within the first recess and the first magnetic gap. Since the dimensions of the first and second transducers along the first direction remain unchanged, the distance the first moving coil reciprocates along the first direction is increased. This increases the amplitude of the first transducer without altering the overall thickness of the loudspeaker, thereby enhancing the loudspeaker's external sounding performance.

[0101] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0102] refer to Figure 1 This application provides an electronic device that may include a screen, a housing, a keyboard, and a speaker 1, wherein the speaker 1 can be disposed within the housing. The keyboard can be disposed on the housing, and the keyboard and speaker 1 are correspondingly disposed. The speaker 1 can effectively reduce vibration by utilizing the principle of force cancellation, thereby reducing keyboard vibration noise and improving the user experience of the electronic device.

[0103] In some embodiments, the electronic device may include, but is not limited to, a mobile or fixed terminal with a speaker 1, such as a tablet computer, laptop computer, ultra-mobile personal computer (UMPC), handheld computer, netbook, or personal digital assistant (PDA). For example, the electronic device may be a laptop computer.

[0104] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This application also provides a loudspeaker 1, which may include a mounting frame 100, a first transducer mechanism 200, and a second transducer mechanism 300. In some embodiments, the first transducer mechanism 200 and the second transducer mechanism 300 may be symmetrically arranged about the mounting frame 100.

[0105] refer to Figure 3 and Figure 4 The mounting frame 100 may include a first direction (e.g., Figure 3 The first mounting groove 110 and the second mounting groove 120 are arranged opposite each other in the Z direction. The bottoms of the first mounting groove 110 and the second mounting groove 120 can be arranged correspondingly. The bottoms of the first mounting groove 110 and the second mounting groove 120 are connected. The inner bottom wall of the first mounting groove 110 can have a first recess 111.

[0106] refer to Figure 3 and Figure 4 In some embodiments, a first sound-venting hole 113 is provided on the mounting frame 100 at a position corresponding to the side wall of the first mounting groove 110, and a second sound-venting hole 123 is also provided on the mounting frame 100 at a position corresponding to the side wall of the second mounting groove 120.

[0107] In one possible embodiment, the mounting frame 100 may include two plate-like structures, the two plate-like structures being aligned in a first direction (e.g., Figure 3 The two plate-like structures are stacked in the Y direction, and are connected or abutting each other. One plate-like structure can be used to form the bottom of the first mounting groove 110, and the other plate-like structure can be used to form the bottom of the second mounting groove 120.

[0108] In another possible embodiment, the mounting frame 100 may further include a plate-like structure, with the first mounting groove 110 and the second mounting groove 120 sharing the same plate-like structure. The side of the plate-like structure facing the first mounting groove 110 may be the inner bottom wall of the first mounting groove 110, and the side of the plate-like structure facing the second mounting groove 120 may be the inner bottom wall of the second mounting groove 120. The surface of the plate-like structure facing the first mounting groove 110 may have a first recess 111.

[0109] refer to Figure 3 and Figure 4 In a specific implementation, the mounting frame 100 may include an outer frame 130 and a mounting plate 140. The outer frame 130 may form the sidewalls of the first mounting groove 110 and the second mounting groove 120. The mounting plate 140 is disposed inside the outer frame 130 and is used to divide the outer frame 130 into the first mounting groove 110 and the second mounting groove 120. The mounting plate 140 may also form the bottom wall of the first mounting groove 110 and the second mounting groove 120. The mounting plate 140 may have a first surface 141 and a second surface 142 that are opposite each other along a first direction. The first surface 141 is the inner bottom wall of the first mounting groove 110, and the second surface 142 is the inner bottom wall of the second mounting groove 120.

[0110] In this way, the structure of the outer frame 130 and the mounting plate 140 is relatively simple and the number of parts is relatively small, which can simplify the manufacturing process of the mounting frame 100 and improve the assembly efficiency of the mounting frame 100.

[0111] In some embodiments, the mounting plate 140 may be detachably connected to the outer frame 130, which facilitates the separate disassembly and maintenance of the mounting plate 140 and the outer frame 130. Alternatively, the mounting plate 140 and the outer frame 130 may be an integral structure.

[0112] refer to Figure 4 and Figure 5 The first transducer 200 is disposed within the first mounting groove 110. This allows the first transducer 200 to be circumferentially limited by the side wall of the first mounting groove 110, and also provides circumferential protection for the first transducer 200, reducing the probability of the first transducer 200 being damaged by external impacts.

[0113] In some embodiments, the first transducer 200 can be completely located within the first mounting groove 110, and the first transducer 200 does not protrude from the opening of the first mounting groove 110.

[0114] The first transducer 200 may include a first magnetic circuit unit 210 and a first moving coil 220. The first magnetic circuit unit 210 may have a first magnetic gap 211 corresponding to the first recess 111, and the first magnetic gap 211 is connected to the first recess 111. The first moving coil 220 is disposed in the first magnetic gap 211, and at least a portion of the first moving coil 220 moves along a first direction into the first recess 111, thereby making the first recess 111 part of the first magnetic gap 211 and increasing the distance the first moving coil 220 moves along the first direction.

[0115] The second transducer 300 is disposed within the second mounting groove 120. This allows the second transducer 300 to be circumferentially limited by the side wall of the second mounting groove 120, and also provides circumferential protection for the second transducer 300, reducing the probability of the second transducer 300 being damaged by external impacts.

[0116] In some embodiments, the second transducer 300 can be completely located within the second mounting groove 120, and the second transducer 300 does not protrude from the opening of the second mounting groove 120.

[0117] This application provides a loudspeaker 1. By setting a first recess 111 at a position corresponding to the first magnetic gap 211 on the bottom of the first mounting groove 110 of the mounting frame 100, the first moving coil 220 can not only move in the first magnetic gap 211 along the first direction, but also at least a portion of the first moving coil 220 can move into the first recess 111. This allows the first moving coil 220 to reciprocate along the first direction in the first recess 111 and the first magnetic gap 211. Since the dimensions of the first transducer mechanism 200 and the second transducer mechanism 300 along the first direction remain unchanged, the distance of the first moving coil 220 reciprocating along the first direction is increased. This increases the amplitude of the first transducer mechanism 200 without changing the overall thickness of the loudspeaker 1, thereby improving the external playback performance of the loudspeaker 1.

[0118] Furthermore, when the speaker 1 of this application is applied in an electronic device, it can improve the audio output effect of the electronic device without changing the thickness of the speaker 1 in the first direction and while ensuring the vibration reduction effect, thereby improving the user's experience of using the electronic device.

[0119] refer to Figure 4 In some embodiments, the first transducer mechanism 200 may include two, both of which can be disposed within the first mounting groove 110, and the two transducers are aligned along a second direction (e.g., Figure 4 The spacing in the X direction is set so that by setting two first transducer mechanisms 200, the external sound effect of the speaker 1 can be increased and the performance of the speaker 1 can be improved.

[0120] In some embodiments, the second transducer mechanism 300 may include two, both of which are disposed within the second mounting groove 120, and the two transducers are aligned along a second direction (e.g., Figure 4 The spacing in the X direction is set, and by setting two second transducer mechanisms 300, the external sound effect of the speaker 1 can be increased and the performance of the speaker 1 can be improved.

[0121] refer to Figure 4 and Figure 5 In some embodiments, the first magnetic circuit unit 210 may further include a first central magnet 212, a first side magnet 213 and a first yoke 214.

[0122] The first central magnet 212 is disposed in the first mounting groove 110, and the first recess 111 can be annular, and the annular first recess 111 can surround the outer periphery of the first central magnet 212.

[0123] The first side magnet 213 is arranged around the outer periphery of the first central magnet 212 and is located on the outer edge of the first recess 111, forming a first magnetic gap 211 between the first side magnet 213 and the first central magnet 212.

[0124] The first magnetic yoke 214 is disposed on the side of the first central magnet 212 facing away from the second transducer 300. The first magnetic yoke 214 covers the first magnetic gap 211 and is connected to the first side magnet 213. This allows the first central magnet 212 to be connected to the first side magnet 213 through the first magnetic yoke 214, and the first central magnet 212, the first magnetic yoke 214, and the first side magnet 213 to form a complete magnetic circuit.

[0125] In some embodiments, the first central magnet 212 can be a permanent magnet structure. The first central magnet 212, the first yoke 214, and the first side magnet 213 can form a complete magnetic circuit, enabling the first transducer 200 to form an internal magnet transducer. The first central magnet 212, as a permanent magnet, is wrapped by the first side magnet 213. The magnetic circuit of the first magnetic circuit unit 210 contracts centripetally, resulting in a smaller volume compared to an external magnet transducer, which helps to reduce the volume of the first transducer 200 and, consequently, the volume of the speaker 1.

[0126] refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the bottom wall of the first recess 111 is provided with a first through hole 112 that connects the first mounting groove 110 and the second mounting groove 120. The first through hole 112 is correspondingly provided with the first moving coil 220, and at least a portion of the first moving coil 220 can move into the first through hole 112 along the first direction.

[0127] In this way, the first moving coil 220 can be moved further into the first through hole 112 along the first direction, thereby further increasing the moving distance of the first moving coil 220 in the first direction and further increasing the amplitude of the first transducer 200.

[0128] In some embodiments, the second transducer 300 includes a second magnetic circuit unit 310 and a second moving coil 320. The second magnetic circuit unit 310 may have a second magnetic gap 311 corresponding to the first through hole 112, and the second magnetic gap 311 is connected to the first through hole 112. At least a portion of the structure of the second moving coil 320 can move along a first direction into the first through hole 112, thereby increasing the moving distance of the second moving coil 320 along the first direction, thereby increasing the amplitude of the second transducer 300 and improving the external sound output of the speaker 1.

[0129] Since the first central magnet 212 is connected to the first side magnet 213 via the first yoke 214, a through hole can be provided on the bottom wall of the first mounting groove 110 at the position corresponding to the first central magnet 212. The through hole can communicate with the first through hole 112, so that the area surrounded by the first through hole 112 on the bottom wall of the first mounting groove 110 is completely hollowed out. The first central magnet 212 can directly contact the second central magnet 312.

[0130] refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the first magnetic yoke 214 has a third recess 114 on the side facing the first moving coil 220, and the third recess 114 is connected to the first magnetic gap 211. In this way, a part of the structure of the first moving coil 220 can be moved into the third recess 114 along the first direction, thereby increasing the movement amplitude of the first moving coil 220 along the first direction, thereby increasing the amplitude of the first transducer mechanism 200 and improving the external playback performance of the speaker 1.

[0131] In some embodiments, the first magnetic yoke 214 does not protrude from the opening of the first mounting groove 110. For example, the plane where the first magnetic yoke 214 is located may be lower than the plane where the opening of the first mounting groove 110 is located, or the plane where the first magnetic yoke 214 is located may be flush with the plane where the opening of the first mounting groove 110 is located.

[0132] This avoids the first magnetic yoke 214 from protruding from the first mounting groove 110, reduces the thickness of the speaker 1 along the first direction, and reduces the probability of the outer periphery of the first magnetic yoke 214 being hit, thereby improving the durability and service life of the first magnetic yoke 214.

[0133] refer to Figure 4 and Figure 5In some embodiments, the first transducer 200 may further include a first vibration component 230, which is disposed around the outer periphery of the first magnetic circuit unit 210, and one side of the first vibration component 230 is connected to the first magnetic circuit unit 210, and the other side of the first vibration component 230 is connected to the inner wall of the first mounting groove 110.

[0134] In some embodiments, there is a gap between the first magnetic circuit unit 210 and the sidewall of the first mounting groove 110, and the first vibration component 230 can be located within the gap so that the first vibration component 230 surrounds the outer periphery of the first magnetic circuit unit 210, which can prevent the first vibration component 230 from increasing the thickness of the first transducer 200 along the first direction, thereby preventing the increase of the thickness of the speaker 1 along the first direction, and helping to reduce the space occupied by the speaker 1 in the thickness direction.

[0135] refer to Figure 5 and Figure 7 In some embodiments, the first vibration component 230 is disposed away from the inner bottom wall of the first mounting groove 110. Alternatively, the first vibration component 230 is disposed close to the inner bottom wall of the first mounting groove 110.

[0136] refer to Figure 4 and Figure 5 In some embodiments, the first vibration component 230 may include a first diaphragm 231, a first frame 232, a first transmission component 233, and a first flexible circuit board 234.

[0137] A first diaphragm 231 is disposed around the outer periphery of the first magnetic circuit unit 210. One side of the first diaphragm 231 is connected to the mounting frame 100, and the other side is connected to the first magnetic circuit unit 210. A first frame 232 is disposed around the outer periphery of the first magnetic circuit unit 210. One side of the first frame 232 is connected to the first moving coil 220, and the other side is connected to the first diaphragm 231. A first flexible circuit board 234 is electrically connected to the first moving coil 220. A first transmission member 233 can be disposed on the first diaphragm 231 at the middle part along the side wall of the first mounting groove 110 to the first magnetic circuit unit 210, and the first transmission member 233 is connected to the first frame 232.

[0138] By setting the first flexible circuit board 234, current can be transmitted to the first moving coil 220. The flexible circuit board has good flexibility and can be bent in any shape, which helps to adapt to different installation spaces. In addition, the thickness of the first flexible circuit board 234 is relatively thin, which can reduce the occupancy rate of the internal space of the speaker 1.

[0139] Furthermore, the first frame 232 can transmit the vibration of the first moving coil 220 to the first transmission member 233, so that the first frame 232 drives the first transmission member 233 to reciprocate along the first direction. The first transmission member 233 further drives the first diaphragm 231 to reciprocate along the first direction. The structural strength of the first transmission member 233 is greater than that of the first diaphragm 231, and the ability of the first transmission member 233 to overcome air resistance and vibrate along the first direction is greater than that of the first diaphragm 231. Therefore, by setting the first transmission member 233, it can help drive the first diaphragm 231 to reciprocate along the first direction, thereby ensuring the vibration effect of the first diaphragm 231.

[0140] The first transmission component 233 can be disposed at the middle part of the first diaphragm 231 along the side wall of the first mounting groove 110 to the first magnetic circuit unit 210, thereby making the vibration amplitude distribution on the first diaphragm 231 more uniform and avoiding audio distortion.

[0141] In some embodiments, if the first magnetic circuit unit 210 may include a first magnetic yoke 214 and a first side magnet 213, then the end of the first diaphragm 231 connected to the first magnetic circuit unit 210 can be clamped between the first magnetic yoke 214 and the first side magnet 213, thereby improving the connection stability between the first magnetic circuit unit 210 and the first diaphragm 231. Additionally, the first transducer mechanism 200 may also include a sealing element disposed between the first side magnet 213 and the first diaphragm 231. The sealing element can be used to seal the gap between the first side magnet 213 and the first diaphragm 231, and furthermore, the sealing element can mitigate the damage to the first diaphragm 231 caused when the first side magnet 213 directly clamps the first diaphragm 231.

[0142] refer to Figure 4 In some embodiments, the first vibration component 230 may further include a first adjustment diaphragm 235. One end of the first adjustment diaphragm 235 is connected to the inner wall of the first mounting groove 110, and the other end is connected to the first flexible circuit board 234, which is connected to the first frame 232. The vibration of the first moving coil 220 can be transmitted to the first flexible circuit board 234 through the first frame 232, and further transmitted by the first flexible circuit board 234 to the first adjustment diaphragm 235. The first adjustment diaphragm 235 can be used to adjust the polarization and mixing of the first diaphragm 231.

[0143] In this way, by setting the first adjustment diaphragm 235, the polarization and mixing of the first diaphragm 231 can be suppressed, the vibration effect of the first transducer 200 can be improved, and the external playback effect of the speaker 1 can be improved.

[0144] refer to Figure 4 and Figure 5In some embodiments, the inner bottom wall of the second mounting groove 120 may have a second recess 121 corresponding to the first recess 111. The second transducer mechanism 300 may include a second magnetic circuit unit 310 and a second moving coil 320.

[0145] The second magnetic circuit unit 310 may have a second magnetic gap 311 corresponding to the second recess 121, and the second magnetic gap 311 is connected to the second recess 121. The second moving coil 320 is disposed in the second magnetic gap 311, and at least a portion of the second moving coil 320 moves along the first direction into the second recess 121, so that the second recess 121 can be used as part of the second magnetic gap 311, thereby increasing the distance that the second moving coil 320 moves along the first direction.

[0146] The speaker 1 has a second recess 121 provided on the bottom of the second mounting groove 120 of the mounting frame 100 at a position corresponding to the second magnetic gap 311. This allows the second moving coil 320 to not only move in the second magnetic gap 311 along the first direction, but also allows at least a portion of the second moving coil 320 to move into the second recess 121. This enables the second moving coil 320 to reciprocate in the second recess 121 and the second magnetic gap 311 along the first direction. Since the dimensions of the second transducer 300 and the second transducer 300 along the first direction remain unchanged, the distance of the second moving coil 320 reciprocating in the first direction is increased. This increases the amplitude of the second transducer 300 without changing the overall thickness of the speaker 1, thereby improving the external playback performance of the speaker 1.

[0147] refer to Figure 4 and Figure 5 In some embodiments, the second magnetic circuit unit 310 may have the same structure as the first magnetic circuit unit 210. The second magnetic circuit unit 310 may also include a second central magnet 312, a second side magnet 313, and a second yoke 314.

[0148] The second central magnet 312 is disposed in the second mounting groove 120, and the second recess 121 can be annular, and the annular second recess 121 can surround the outer periphery of the second central magnet 312.

[0149] The second side magnet 313 is arranged around the outer periphery of the second central magnet 312 and is located on the outer edge of the second recess 121, forming a second magnetic gap 311 between the second side magnet 313 and the second central magnet 312.

[0150] The second magnetic yoke 314 is disposed on the side of the second central magnet 312 facing away from the first transducer 200. The second magnetic yoke 314 covers the second magnetic gap 311 and is connected to the second side magnet 313. This allows the second central magnet 312 to be connected to the second side magnet 313 through the second magnetic yoke 314, and enables the second central magnet 312, the second magnetic yoke 314, and the second side magnet 313 to form a complete magnetic circuit.

[0151] In some embodiments, the second central magnet 312 can be a permanent magnet structure. The second central magnet 312, the second yoke 314, and the second side magnet 313 can form a complete magnetic circuit and enable the second transducer 300 to form an internal magnetic transducer. The second central magnet 312, as a permanent magnet, is wrapped by the second side magnet 313. The magnetic circuit of the second magnetic circuit unit 310 contracts centripetally, resulting in a smaller volume compared to an external magnetic transducer, which helps to reduce the volume of the second transducer 300 and thus helps to reduce the volume of the speaker 1.

[0152] refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the bottom wall of the second recess 121 is provided with a second through hole 122 that connects the first mounting groove 110 and the second mounting groove 120. The second through hole 122 is correspondingly provided with the second moving coil 320, and at least a portion of the second moving coil 320 can move into the second through hole 122 along the first direction.

[0153] In this way, the second moving coil 320 can be moved further into the second through hole 122 along the first direction, thereby further increasing the moving distance of the second moving coil 320 in the first direction and further increasing the amplitude of the second transducer 300.

[0154] In some embodiments, if the second recess 121 is provided correspondingly to the first recess 111, the second through hole 122 of the second recess 121 can communicate with the first recess 111. If the first recess 111 has a first through hole 112, the first through hole 112 and the second through hole 122 can communicate with each other.

[0155] refer to Figure 5 and Figure 6 In some embodiments, the second magnetic yoke 314 has a fourth recess 124 on the side facing the second moving coil 320, and the fourth recess 124 is connected to the second magnetic gap 311.

[0156] In this way, a portion of the structure of the second moving coil 320 can be moved along the first direction into the fourth recess 124, thereby increasing the movement amplitude of the second moving coil 320 along the first direction, thereby increasing the amplitude of the second transducer mechanism 300 and improving the external playback performance of the speaker 1.

[0157] In some embodiments, the second magnetic yoke 314 does not protrude from the opening of the second mounting groove 120. For example, the plane on which the second magnetic yoke 314 is located may be lower than the plane on which the opening of the second mounting groove 120 is located, or the plane on which the second magnetic yoke 314 is located may be flush with the plane on which the opening of the second mounting groove 120 is located.

[0158] This prevents the second magnetic yoke 314 from protruding from the second mounting groove 120, reduces the thickness of the speaker 1 along the first direction, and reduces the probability of the outer periphery of the second magnetic yoke 314 being hit, thereby improving the durability and service life of the second magnetic yoke 314.

[0159] refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the second transducer 300 may further include a second vibration component 330, which surrounds the outer periphery of the second magnetic circuit unit 310, and one side of the second vibration component 330 is connected to the second magnetic circuit unit 310, while the other side of the second vibration component 330 is connected to the inner wall of the second mounting groove 120.

[0160] In some embodiments, there is a gap between the second magnetic circuit unit 310 and the sidewall of the second mounting groove 120, and the second vibration component 330 can be located within the gap so that the second vibration component 330 surrounds the outer periphery of the second magnetic circuit unit 310. This can prevent the second vibration component 330 from increasing the thickness of the second transducer mechanism 300 along the first direction, thereby preventing the increase of the thickness of the speaker 1 along the first direction and helping to reduce the space occupied by the speaker 1 in the thickness direction.

[0161] If the second magnetic circuit unit 310 has a second side magnet 313, then the second vibration component 330 can be disposed on the outer periphery of the second side magnet 313.

[0162] refer to Figure 5 and Figure 7 In some embodiments, the second vibration component 330 can be disposed away from the inner bottom wall of the second mounting groove 120. Alternatively, the second vibration component 330 can be disposed close to the inner bottom wall of the second mounting groove 120.

[0163] If the first transducer 200 and the second transducer 300 can be symmetrically arranged, the first vibration component 230 is arranged away from the inner bottom wall of the first mounting groove 110, and the second vibration component 330 is also arranged away from the inner bottom wall of the second mounting groove 120, then the loudspeaker 1 can realize the "back-to-back" arrangement of the first transducer 200 and the second transducer 300.

[0164] The first transducer 200 and the second transducer 300 are arranged in a "back-to-back" manner, which allows the two transducers to move in opposite directions. By canceling each other out by inertial force, the vibration energy transmitted to the device casing is greatly reduced, keyboard resonance noise is reduced, and touch stability is improved.

[0165] If the first transducer 200 and the second transducer 300 can be symmetrically arranged, the first vibration component 230 is arranged close to the inner bottom wall of the first mounting groove 110, and the second vibration component 330 is also arranged close to the inner bottom wall of the second mounting groove 120, then the loudspeaker 1 can achieve a "face-to-face" arrangement of the first transducer 200 and the second transducer 300.

[0166] refer to Figure 4 and Figure 5 In some embodiments, the second vibration component 330 may include a second diaphragm 331, a second frame 332, a second transmission element 333, and a second flexible circuit board 334.

[0167] A second diaphragm 331 is disposed around the outer periphery of the second magnetic circuit unit 310. One side of the second diaphragm 331 is connected to the mounting frame 100, and the other side is connected to the second magnetic circuit unit 310. A second frame 332 is disposed around the outer periphery of the second magnetic circuit unit 310. One side of the second frame 332 is connected to the second moving coil 320, and the other side is connected to the second diaphragm 331. A second flexible circuit board 334 is electrically connected to the second moving coil 320. A second transmission member 333 can be disposed on the second diaphragm 331 at the middle part along the side wall of the second mounting groove 120 to the second magnetic circuit unit 310, and the second transmission member 333 is connected to the second frame 332.

[0168] By setting the second flexible circuit board 334, current can be transmitted to the second moving coil 320. The flexible circuit board has good flexibility and can be bent in any shape, which helps to adapt to different installation spaces. In addition, the thickness of the second flexible circuit board 334 is relatively thin, which can reduce the occupancy rate of the internal space of the speaker 1.

[0169] Furthermore, the second frame 332 can transmit the vibration of the second moving coil 320 to the second transmission member 333, so that the second frame 332 drives the second transmission member 333 to reciprocate along the second direction. The second transmission member 333 further drives the second diaphragm 331 to reciprocate along the second direction. The structural strength of the second transmission member 333 is greater than that of the second diaphragm 331, and the ability of the second transmission member 333 to overcome air resistance and vibrate along the second direction is greater than that of the second diaphragm 331. Therefore, by setting the second transmission member 333, it is helpful to drive the second diaphragm 331 to reciprocate along the second direction, thereby ensuring the vibration effect of the second diaphragm 331.

[0170] The second transmission component 333 can be disposed on the second diaphragm 331 in the middle of the direction from the side wall of the second mounting groove 120 to the second magnetic circuit unit 310, thereby making the vibration amplitude distribution on the second diaphragm 331 more uniform and avoiding audio distortion.

[0171] refer to Figure 4 and Figure 5 In some embodiments, the second vibration assembly 330 may further include a second adjustment diaphragm 335. One end of the second adjustment diaphragm 335 is connected to the inner wall of the second mounting groove 120, and the other end is connected to the second flexible circuit board 334, which is connected to the second frame 332. The vibration of the second moving coil 320 can be transmitted to the second flexible circuit board 334 through the second frame 332, and further transmitted by the second flexible circuit board 334 to the second adjustment diaphragm 335. The second adjustment diaphragm 335 can be used to adjust the polarization and mixing of the second diaphragm 331.

[0172] In this way, by setting the second adjustment diaphragm 335, the polarization and mixing of the second diaphragm 331 can be suppressed, the vibration effect of the second transducer 300 can be improved, and the external playback effect of the speaker 1 can be improved.
