[0035] The woofer and tweeter each occupy space within the electronic device, resulting in an inability to install more electronic components within the electronic device.

[0036] In view of this, the present disclosure proposes a speaker device 10, which can be provided with a first speaker 131 and a second speaker 132. Among the first speaker 131 and the second speaker 132, one is a woofer 13 and the other is a tweeter 13, and the first speaker 131 and the second speaker 132 are coaxially arranged. In this way, the integration of the first speaker 131 and the second speaker 132 can be improved, so as to reduce the space occupied in the electronic device in which the speaker device 10 is installed, so that more electronic components can be installed in the electronic device.

[0037] First aspect

[0038] The present disclosure provides a speaker device 10, see Figures 1 to 8As shown, the speaker device 10 may include: a diaphragm 11, a shell 12 and a speaker 13, the shell 12 and the diaphragm 11 enclose a receiving space 121; the speaker 13 is arranged in the receiving space 121, and the speaker 13 may include: a first speaker 131 and a second speaker 132, the first speaker 131 and the second speaker 132 are coaxially arranged and respectively connected to the diaphragm 11, the first speaker 131 is located at the axial position of the second speaker 132, the first magnetic circuit structure 1312 of the first speaker 131 is arranged in the receiving space 121, and the first magnetic circuit structure 1312 is separated from the diaphragm 11 under the action of the shell 12; wherein, the first speaker 131 and the second speaker 132 have different coverage frequency ranges.

[0039] The diaphragm 11 can push the air to generate sound waves when it vibrates.

[0040] The housing 12 may have a groove, the opening of which may be connected to the diaphragm 11 so as to close the opening of the groove through the diaphragm 11, thereby forming a receiving space 121 in cooperation with the diaphragm 11 and the housing 12. Part or all of the housing 12 may be made of magnetic material to provide a stable magnetic field environment for the diaphragm 11, for example: Figure 4 As shown, two magnetic members 127 are detachably connected to the bottom of the housing 12 , and the two magnetic members 127 are symmetrically arranged to provide a more stable magnetic field environment.

[0041] The speaker 13 may include a first speaker 131 (e.g., a tweeter) and a second speaker 132 (e.g., a woofer) disposed within the housing 121 and respectively connected to the diaphragm 11. When energized, the first and second speakers 131, 132 may vibrate to push the diaphragm 11 to vibrate, thereby causing the diaphragm 11 to push air to generate sound waves. The first speaker 131 may include a first voice coil 1311 and a first magnetic circuit structure 1312. The first voice coil 1311 is connected to the diaphragm 11. The first magnetic circuit structure 1312 is connected to the housing 12 and spaced apart from the diaphragm 11. The first magnetic circuit structure 1312 provides a stable first magnetic field to the first voice coil 1311. When energized, the first voice coil 1311 generates a changing second magnetic field. Thus, the changing second magnetic field interacts with the stable first magnetic field, causing the first voice coil 1311 to generate a first vibration. Second speaker 132 may include a second voice coil 1321 and a second magnetic circuit structure 1322. Second voice coil 1321 is connected to diaphragm 11, and second magnetic circuit structure 1322 is connected to housing 12. A stable third magnetic field is provided to second voice coil 1321. When energized, second voice coil 1321 generates a variable fourth magnetic field. The variable fourth magnetic field interacts with the stable third magnetic field, causing second voice coil 1321 to vibrate second. The difference between the first and second vibrations causes correspondingly different vibrations in diaphragm 11, thereby generating sound waves. Due to the difference between the first and second vibrations, first speaker 131 and second speaker 132 cover different frequency ranges.

[0042] In one example, see Figures 1 to 5 As shown, the speaker device 10 may include: a diaphragm 11, a shell 12 and a speaker 13, the shell 12 has a groove, the diaphragm 11 is connected to the opening of the groove to close the opening of the groove, so that the shell 12 and the diaphragm 11 enclose a receiving space 121; the speaker 13 is arranged in the receiving space 121. The speaker 13 may include: a first speaker 131 and a second speaker 132, the first speaker 131 and the second speaker 132 are coaxially arranged and respectively connected to the diaphragm 11, and the first speaker 131 is located at the axial position of the second speaker 132; the first speaker 131 may include: a first voice coil 1311 and a first magnetic circuit structure 1312, the first voice coil 1311 is connected to the diaphragm 11, and the first magnetic circuit structure 1312 is connected to the shell 12 and separated from the diaphragm 11; the second speaker 132 may include: a second voice coil 1321 and a second magnetic circuit structure 1322, the second voice coil 1321 is connected to the diaphragm 11, and the second magnetic circuit structure 1322 is connected to the shell 12; wherein, the first speaker 131 and the second speaker 132 have different coverage frequency ranges, so that the first speaker 131 can be a tweeter and the second speaker 132 can be a woofer.

[0043] In this embodiment, the speaker device 10 is provided with a first speaker 131 and a second speaker 132. When the first and second speakers 131, 132 are powered on and in operation, the first voice coil 1311 of the first speaker 131 generates a first vibration due to the magnetic field force of the first magnetic circuit structure 1312 of the first speaker 131. The second voice coil 1321 of the second speaker 132 generates a second vibration due to the magnetic field force of the second magnetic circuit structure 1322 of the second speaker 132. The first and second vibrations cause the diaphragm 11 to vibrate, emitting sound. Because the first and second speakers 131, 132 are coaxially arranged, the integration of the first and second speakers 131, 132 is improved, thereby reducing the space occupied by the electronic device in which the speaker device 10 is installed, thereby allowing for the inclusion of more electronic components within the electronic device. Furthermore, the first magnetic circuit structure 1312 of the first speaker 131 is separated from the diaphragm 11 by the housing 12 to prevent resonance.

[0044] In some embodiments, see Figure 4 As shown, the first voice coil 1311 of the first speaker 131 is annular, with one axial end of the first voice coil 1311 connected to the diaphragm 11. The second voice coil 1321 of the second speaker 132 is annular, arranged outside the first voice coil 1311, and one axial end of the second voice coil 1321 is connected to the diaphragm 11. In other words, the second voice coil 1321 wraps around the outside of the first voice coil 1311, and both surfaces on the same side of the first and second voice coils 1311, 1321 are connected to the diaphragm 11, so that the first and second voice coils 1311, 1321 are coaxially arranged.

[0045] For example, the first voice coil 1311 is in the shape of a rectangular ring, and the second voice coil 1321 is in the shape of a rectangular ring and is disposed outside the first voice coil 1311 . The first voice coil 1311 and the second voice coil 1321 are similar.

[0046] For another example, the first voice coil 1311 is rectangular with rounded corners, and the second voice coil 1321 is rectangular with rounded corners and is disposed outside the first voice coil 1311 . The first voice coil 1311 and the second voice coil 1321 are similar.

[0047] In this embodiment, the first voice coil 1311 and the second voice coil 1321 are coaxially arranged to achieve the coaxial arrangement of the first speaker 131 and the second speaker 132. In addition, the first voice coil 1311 and the second voice coil 1321 are both annular, so that the two can be designed to be similar but of different sizes, thereby making the arrangement of the first voice coil 1311 and the second voice coil 1321 regular and having a good visual effect.

[0048] During the implementation process, the first voice coil 1311 can be bonded to the diaphragm 11 through the annular first bracket 111 (with stronger adhesion), and the second voice coil 1321 can also be bonded to the diaphragm 11 through the annular bracket (with stronger adhesion), so as to improve the firmness of the connection between the diaphragm 11, the first voice coil 1311 and the second voice coil 1321.

[0049] In some embodiments, see Figures 2 to 6 As shown, the first magnetic circuit structure 1312 may include: a first magnetic member 1313, a first magnetic conductor 1314 and a second magnetic conductor 1315; at least part of the first magnetic member 1313 is arranged in the annular space of the first voice coil 1311; the first magnetic conductor 1314 is arranged on the side of the first magnetic member 1313 corresponding to the diaphragm 11; at least part of the second magnetic conductor 1315 is arranged on the side of the first magnetic member 1313 away from the diaphragm 11, and at least part of it corresponds to the outside of the first voice coil 1311.

[0050] The first magnetic member 1313 may be Figures 2 to 6 The plate-like structure shown in the figure may also be a structure formed by splicing multiple blocks, or may be arranged in other forms. The first magnetic member 1313 can generate a stable first magnetic field, which can be made of materials such as neodymium iron boron or ferrite. The first magnetic conductor 1314 can be Figures 2 to 6 The plate-like structure shown in the figure may also be a structure formed by splicing a plurality of blocks, or may be other forms of arrangement. Part of the second magnet 1315 is located on the side of the first magnetic member 1313 away from the diaphragm 11, and part of it is located on the outside of the first voice coil 1311. In this way, a recessed space may be formed on the side of the second magnet 1315 corresponding to the first magnetic member 1313, and the first magnetic member 1313 and the first magnet 1314 may be arranged in the recessed space; and the first magnet 1314 and the second magnet 1315 are respectively located on both sides of the first magnetic member 1313 to cooperate with the first magnetic member 1313 to form a closed magnetic circuit, thereby cooperating to provide a stable and uniform first magnetic field to the first voice coil 1311.

[0051] In some embodiments, see Figures 2 to 8 As shown, the speaker device 10 may further include: a support member 14, the two ends of which are respectively connected to the first inner wall 122 and the second inner wall 123 of the shell 12 opposite to each other, so as to be suspended between the diaphragm 11 and the first surface 124 of the shell 12 opposite to the diaphragm 11, and the side of the support member 14 corresponding to the diaphragm 11 is connected to the side of the second magnetic conductor 1315 away from the first magnetic member 1313, so as to suspend the first magnetic circuit structure 1312 in the accommodating space 121, and the support member 14 can reciprocate between the diaphragm 11 and the first surface 124.

[0052] The support member 14 can be a structural member with buffering properties, such as a thin steel sheet. Its two ends are respectively connected to the first inner wall 122 and the second inner wall 123, and one side is connected to the side of the second magnetic conductor 1315 facing away from the first magnetic member 1313, thereby connecting the first magnetic circuit structure 1312 to one side of the support member 14 and separating it from the diaphragm 11. The first voice coil 1311 vibrates under the stable first magnetic field provided by the first magnetic circuit structure 1312, and the first magnetic circuit structure 1312 also vibrates. The support member 14 is connected to the housing 12 and the first magnetic circuit structure 1312, and the support member 14 provides a buffering force for reciprocating motion between the diaphragm 11 and the first surface 124. In this way, the vibration amplitude of the first magnetic circuit structure 1312 can be reduced, thereby achieving shock absorption.

[0053] In some embodiments, see Figure 3 、 Figure 4 、 Figure 7 and Figure 8 As shown, the support member 14 may include: a connecting rod 141, a first connecting portion 142 and a second connecting portion 143, one end of the connecting rod 141 is connected to the first inner wall 122 through the first connecting portion 142, and the other end is connected to the second inner wall 123 through the second connecting portion 143, and the first connecting portion 142 and the second connecting portion 143 are symmetrical or asymmetrical about the connecting rod 141; wherein, the first connecting portion 142 is V-shaped, the outer side of the corner of the first connecting portion 142 is connected to one end of the connecting rod 141, and both ends of the first connecting portion 142 are connected to the first inner wall 122; or, the first connecting portion 142 is U-shaped, the outer side of the corner of the first connecting portion 142 is connected to one end of the connecting rod 141, and both ends of the first connecting portion 142 are connected to the first inner wall 122.

[0054] In one example, see Figure 3 and Figure 4 As shown, the first connecting portion 142 and the second connecting portion 143 are symmetrically arranged at both ends of the connecting rod 141. The first connecting portion 142 and the second connecting portion 143 are both V-shaped. In this way, the connecting rod 141 and the first connecting portion 142 cooperate to form a Y-shape, and the connecting rod 141 and the second connecting portion 143 cooperate to form a Y-shape. The two ends of the first connecting portion 142 are connected to the first inner wall 122, and the two ends of the second connecting portion 143 are connected to the second inner wall 123. The symmetry of the first connecting portion 142 and the second connecting portion 143 makes the connection between the support member 14 and the housing 12 more stable, thereby providing more stable support for the first magnetic circuit structure 1312 and providing more stable cushioning to achieve more stable shock absorption.

[0055] In one example, see Figure 7As shown, the first connecting portion 142 and the second connecting portion 143 are symmetrically arranged at both ends of the connecting rod 141. The first connecting portion 142 and the second connecting portion 143 are both U-shaped. In this way, the connecting rod 141 and the first connecting portion 142 cooperate to form an approximately Y-shape, and the connecting rod 141 and the second connecting portion 143 cooperate to form an approximately Y-shape. The two ends of the first connecting portion 142 are connected to the first inner wall 122, and the two ends of the second connecting portion 143 are connected to the second inner wall 123. The symmetry of the first connecting portion 142 and the second connecting portion 143 makes the connection between the support member 14 and the housing 12 more stable, thereby providing more stable support for the first magnetic circuit structure 1312 and providing more stable cushioning to achieve more stable shock absorption.

[0056] In one example, the first connecting portion 142 and the second connecting portion 143 are respectively disposed at the two ends of the connecting rod 141 and are asymmetrical. The first connecting portion 142 is V-shaped, and the second connecting portion 143 is U-shaped. Thus, the connecting rod 141 and the first connecting portion 142 cooperate to form a Y-shape, and the connecting rod 141 and the second connecting portion 143 cooperate to form a near Y-shape. The two ends of the first connecting portion 142 are connected to the first inner wall 122, and the two ends of the second connecting portion 143 are connected to the second inner wall 123. This also reduces restrictions on the materials used for the first connecting portion 142 and the second connecting portion 143.

[0057] In this embodiment, the support member 14 includes a connecting rod 141, a first connecting portion 142, and a second connecting portion 143. One end of the connecting rod 141 is connected to the first inner wall 122 via the first connecting portion 142, and the other end is connected to the second inner wall 123 via the second connecting portion 143, so that the connecting rod 141 can be disposed within the accommodating space 121. The connecting rod 141 is a rod-shaped member, the first connecting portion 142 is U-shaped or V-shaped, and the second connecting portion 143 is U-shaped or V-shaped, which makes the structure of the support member 14 simple and easy to manufacture.

[0058] In other embodiments, Figure 8 As shown, one end of the support member 14 can have three connecting parts to connect with the first inner wall 122, the third inner wall 125, and the fourth inner wall 126 respectively, and the other end of the support member 14 can also have three connecting parts to connect with the second inner wall 123, the third inner wall 125, and the fourth inner wall 126 respectively.

[0059] In this way, the support member 14 can be provided in various forms for flexible selection.

[0060] In some embodiments, see Figure 5 and Figure 6As shown, the speaker device 10 may further include: a first buffer structure 15, made of rigid material, disposed between the support member 14 and the first surface 124, and having elasticity for reciprocating motion in the direction of the line connecting the support member 14 and the first surface 124; and / or, a second buffer structure 16, made of elastic material, disposed between the support member 14 and the first surface 124, and having elasticity for reciprocating motion in the direction of the line connecting the support member 14 and the first surface 124; wherein, when the speaker device 10 is provided with one of the first buffer structure 15 and the second buffer structure 16, the buffer structures are respectively connected to the support member 14 and the first surface 124; when the speaker device 10 is provided with the first buffer structure 15 and the second buffer structure 16, the first buffer structure 15 and the second buffer structure 16 are superimposed between the support member 14 and the first surface 124 and are respectively connected to the support member 14 and the first surface 124.

[0061] In other words, at least one of the first buffer structure 15 and the second buffer structure 16 can be set on the side of the support member 14 away from the first magnetic circuit structure 1312, and the first buffer structure 15 and the second buffer structure 16 both have a buffering effect. In this way, under the buffering force of the support member 14, the setting of the first buffer structure 15 and / or the second buffer structure 16 can further increase the buffering effect to improve the shock absorption effect.

[0062] The first buffer structure 15 is a spring or a spring made of a rigid material (such as steel), and the second buffer structure 16 is a layer structure made of an elastic material (such as rubber, silicone, sponge, etc.).

[0063] In one example, one end of the spring is connected to the support member 14, and the other end of the spring is spaced apart from or abuts the first surface 124. When the support member 14 moves toward the first surface 124 to buffer the first magnetic circuit structure 1312, the support member 14 squeezes the spring so that the height between the two ends of the spring is reduced to buffer the support member 14.

[0064] In one example, the two ends of the spring are respectively connected to the support member 14 and the first surface 124. When the support member 14 moves toward the first surface 124 to buffer the first magnetic circuit structure 1312, the support member 14 squeezes the spring so that the height between the two ends of the spring is reduced to buffer the support member 14.

[0065] In one example, the rubber layer is connected to the support member 14 and the first surface 124 respectively. When the support member 14 moves toward the first surface 124 to buffer the first magnetic circuit structure 1312, the support member 14 squeezes the rubber layer to reduce the height of the rubber layer to buffer the support member 14.

[0066] In one example, see Figure 6As shown, a first buffer structure 15 (such as a spring) and a second buffer structure 16 (such as a rubber layer) are sequentially arranged between the support member 14 and the first surface 124. When the support member 14 moves toward the first surface 124 to buffer the first magnetic circuit structure 1312, the support member 14 squeezes the first buffer structure 15 and the second buffer structure 16 so that the sum of the heights of the first buffer structure 15 and the second buffer structure 16 is reduced to buffer the support member 14.

[0067] In this embodiment, at least one of the first buffer structure 15 and the second buffer structure 16 can be set between the support member 14 and the first surface 124 to buffer the support member 14 and thereby reduce shock to the first magnetic circuit structure 1312; and at least one of the first buffer structure 15 and the second buffer structure 16 can be set, and the first buffer structure 15 or the second buffer structure 16 can be set, or both the first buffer structure 15 and the second buffer structure 16 can be set, so that flexible selection can be made.

[0068] Of course, the buffer structure (the first buffer structure 15 and / or the second buffer structure 16) may also have a gap with the first surface 124. When the buffer structure moves toward the first surface 124, it first moves a distance to abut the first surface 124 and then its own height decreases.

[0069] In some embodiments, see Figures 2 to 6 As shown, the shell 12 has a third inner wall 125 and a fourth inner wall 126 opposite to each other; the second magnetic circuit structure 1322 of the second speaker 132 includes: a second magnetic part 1323 and a third magnetic part 1324; the second magnetic part 1323 and the third magnetic part 1324 are arranged between the third inner wall 125 and the first magnetic circuit structure 1312, and the second magnetic part 1323 and the third magnetic part 1324 are arranged between the fourth inner wall 126 and the first magnetic circuit structure 1312, and the third inner wall 125, the fourth inner wall 126, the second magnetic part 1323 and the third magnetic part 1324 meet the parallel condition; wherein, the second voice coil 1321 corresponds to between the second magnetic part 1323 and the third magnetic part 1324.

The second magnetic members 1323 and the third magnetic member 1324 on both sides of the first magnetic circuit structure 1312 can provide a stable third magnetic field to the second voice coil 1321, so that the second voice coil 1321 can vibrate when energized.

[0071] The second magnetic member 1323 can be connected to the diaphragm 11 through the second bracket 1325, and the third magnetic member 1324 can be connected to the diaphragm 11 through the third bracket 1326; of course, other settings are also possible and are not specifically limited here.

The connecting plate 17 has a greater hardness than the diaphragm 11. Thus, the connecting plate 17 can enhance the strength of the diaphragm 11 and evenly distribute the vibration of the first voice coil 1311 across the diaphragm 11, thereby improving the sound quality of the speaker device 10.

[0074] In one example, see Figures 1 to 5 As shown, the speaker device 10 may include:
