Description

Technical Field

[0001] The present application relates to the technical field of loudspeakers, and in particular to a combination loudspeaker and electronic device. Background Art

[0002] There is a unique speaker design in the market today, where the treble and bass are cleverly placed in two positions, one above the other, and the sound is emitted in opposite directions, creating a fixed coaxial sound field with high and low frequencies. This design is designed to provide a more balanced and unified listening experience, allowing listeners to enjoy clear highs and full bass at any position.

[0003] However, with the continuous expansion of audio application scenarios, this fixed coaxial sound field design has also faced unprecedented challenges. In some specific audio environments, such as home theaters, small music rooms, recording studios, or car audio systems, the requirements for the sound field are often more complex and changeable. In these scenarios, users may need to fine-tune the direction of the sound field based on factors such as room layout, furniture placement, and sound reflection to achieve the best hearing effect.

[0004] Unfortunately, the traditional design of coaxial speakers with upper and lower split sound sources has a fixed sound field direction and cannot be flexibly adjusted according to the actual needs of users. This not only limits the application scope of the speakers in special scenarios, but also affects the audience's listening experience.

[0005] There is currently no effective technical solution to the above problems. Summary of the invention

[0006] The purpose of the present application is to provide a combined loudspeaker and electronic device so that the direction of the high and low sound fields can be flexibly adjusted.

[0007] In a first aspect, the present application provides a combination speaker, comprising: a tweeter and a woofer, wherein the tweeter comprises a first housing, and the woofer comprises a second housing; The first shell has first arcuate edges on both sides of its cross section, and the second shell has a second arcuate edge on the inner side of its cross section that fits the first arcuate edge; The tweeter is rotatably mounted on the woofer through the cooperation of the first arc edge and the second arc edge.

[0008] The combined speaker of the present application is rotatably connected through the tweeter and the woofer through the outer shell, so that the tweeter can be rotatably adjusted on the woofer to achieve the adjustment of the relative directions of the high and low sound fields, allowing the user to accurately adjust the orientation of the tweeter according to actual needs, providing great flexibility to adapt to different audio environment requirements, and the adjustment structure does not need to introduce additional electronic systems, reducing costs and potential signal interference; in addition, the first outer shell on the tweeter and the second outer shell on the woofer are tightly connected through the arc edge cooperation, which not only ensures the stability and accuracy of the tweeter rotation, but also maintains the compactness of the overall structure.

[0009] In the combined loudspeaker, the outer periphery of the first housing has a first annular wall in a spherical shape, and the inner periphery of the second housing has a second annular wall in a spherical shape and in contact with the first annular wall.

[0010] The above design significantly expands the rotation adjustment range of the tweeter by introducing a spherical annular wall structure between the first shell and the second shell; the spherical annular wall structure allows the tweeter to rotate in all directions on the woofer, no longer restricted by a plane or a simple arc structure. This design solves the problem of limited rotation adjustment range of the tweeter in traditional combination speakers, providing users with more flexible and precise sound field adjustment capabilities.

[0011] In the combined loudspeaker, the first shell and the second shell are in the shape of long strips, the first shell has first arcuate surfaces on both sides corresponding to the first arcuate edges, and the second shell has second arcuate surfaces on both sides corresponding to the second arcuate edges.

[0012] The above design realizes the function of left and right tilt and rotation adjustment of the tweeter on the woofer by designing the first shell and the second shell to be long strips and arranging corresponding curved surfaces on both sides. This design not only increases the flexibility of the speaker, but also enables users to adjust the direction of the sound field according to actual needs, thereby obtaining the best listening experience in different audio environments.

[0013] In the combined loudspeaker, there are a plurality of tweeters, which are arranged along the length direction of the second housing and mounted on the woofer.

[0014] In the combined loudspeaker, a conjugate transmission structure is provided between two adjacent tweeters.

[0015] The combination speaker, wherein the combination speaker further comprises a first rotating member, and the tweeter and the woofer are rotatably connected via the first rotating member.

[0016] The combined loudspeaker, wherein the bottom of the tweeter further includes a first yoke; The tweeter and the woofer are sealed and enclosed to form a transition cavity. The tweeter has a first cavity inside. The first yoke has a plurality of air holes connecting the first cavity and the transition cavity.

[0017] The combined loudspeaker, wherein the bass unit further comprises a second yoke, a second frame, a second magnet, a second voice coil, a second washer and a second diaphragm, The second washer, the second magnet, the second yoke, the second frame and the second diaphragm are sealed and connected in sequence, and the second voice coil is fixed on the second diaphragm; The second magnet and the middle part of the second yoke are connected to form a second groove, and the inner middle part of the tweeter is located in the second groove.

[0018] The combined speaker, wherein one side of the first shell has a plurality of adjustment slots equidistantly arranged along the extension direction of the first arc-shaped edge, and the inner side of the second shell has an elastic snap block that can snap-fit ​​with the adjustment slots to limit the deflection angle of the first shell.

[0037] The disclosure below provides many different embodiments or examples to realize different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.

In addition, the present invention provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0038] In the current field of audio technology, there is a special type of speaker design, in which the tweeter and woofer are placed in two positions, one above and one below, and the sound is emitted in opposite directions, forming a fixed coaxial sound field with opposite high and low frequencies. This design is intended to provide a balanced and unified auditory experience, so that listeners can enjoy clear highs and full bass at any position. However, as users of audio application scenarios may need to fine-tune the direction of the sound field according to factors such as room layout, furniture placement, and sound reflection to continuously expand, this fixed coaxial sound field design faces severe challenges. Specifically, in specific audio environments such as home theaters, small music rooms, recording studios, or car audio systems, the demand for sound fields has become more complex and varied. Get the best hearing effect. However, the traditional upper and lower split, coaxial sounding speaker design cannot meet this flexible adjustment demand, and its sound field direction is fixed and cannot be adjusted according to actual conditions. This not only limits the scope of application of speakers in special scenarios, but also directly affects the quality of the audience's auditory experience.

[0039] To illustrate this issue more concretely, consider a typical home theater system. The system is equipped with a pair of high-end fixed coaxial speakers placed on either side of the TV. The speakers' tweeters and woofers face in fixed directions, forming a preset sound field. However, the special shape of the room and the arrangement of furniture complicate the sound reflection and absorption. For example, there is a large glass window near the right speaker, while there is a fabric sofa on the left. This asymmetrical environment causes significant differences in the sound propagation characteristics of the speakers on both sides. Specifically, high-frequency sounds on the right may be harsh due to reflections from the glass, while high-frequency sounds on the left may be absorbed by the sofa and appear unclear. In addition, the room's ceiling height varies, resulting in inconsistent low-frequency responses from the woofers above at different locations. These factors combine to make the fixed sound field unable to provide an ideal audio experience throughout the listening area. Users may find that the sound clarity, spatial sense, and frequency balance are not satisfactory in certain positions, which seriously affects the overall listening enjoyment.

[0040] If this technical problem cannot be solved, it will have a serious impact on the performance of the entire home theater system. First, the imbalance of the sound field will lead to a decrease in the accuracy of audio reproduction, affecting the clarity of movie dialogues and the performance of music details. Secondly, the fixed sound field direction may produce sound "dead spots" in certain locations, making it impossible for some listeners to obtain an ideal listening experience. Therefore, it is particularly important to develop a speaker system that can flexibly adjust the sound field direction. This can not only improve the adaptability and performance of the system, but also provide users with a more personalized and high-quality listening experience.

[0041] This application has conducted in-depth thinking and exploration on the technical problem that the sound field direction of traditional speakers is fixed and cannot be flexibly adjusted.

[0042] First, please refer to Figure 1-Figure 11 , some embodiments of the present application provide a combined loudspeaker, including: a tweeter 1 and a woofer 2, the tweeter 1 including a first housing 11, the woofer 2 including a second housing 21; The first shell 11 has first arcuate edges 111 on both sides of the cross section, and the second shell 21 has a second arcuate edge 211 on the inner side of the cross section that fits the first arcuate edge 111; The tweeter 1 is rotatably mounted on the woofer 2 by the cooperation of the first arcuate edge 111 and the second arcuate edge 211 .

[0043] Specifically, the tweeter 1 refers to the part of the speaker system responsible for reproducing high-frequency sounds, which can be implemented by a dome tweeter or a ribbon tweeter; the woofer 2 refers to the part of the speaker system responsible for reproducing low-frequency sounds, which can be implemented by a speaker with a large-diameter paper cone or a polypropylene diaphragm; the two are integrated in the same speaker, which can maintain the compact structure of the tweeter 1 and the woofer 2 and avoid the complexity of the separate design. The first shell 11 refers to the external structure that wraps the tweeter 1, which can be made of plastic or metal materials. The second shell 21 refers to the external structure that wraps the woofer 2, which can be made of wood or composite materials. The first arc edge 111 refers to the arc structure on both sides of the cross section of the first shell 11, and the second arc edge 211 refers to the arc structure on the inner side of the cross section of the second shell 21 that fits the first arc edge 111, and can be specifically designed to match the first arc edge 111.

[0044] The working principle of the combined speaker of the embodiment of the present application can be described in detail as follows: First, the tweeter 1 is designed to have a structure of a first housing 11. The first housing 11 has first arcuate edges 111 on both sides of the cross section, and this arcuate design provides a basis for subsequent rotational installation. The curvature and size of the first arcuate edge 111 need to be precisely designed to ensure matching with the woofer 2.

[0045] Secondly, the woofer 2 is designed to have a structure with a second housing 21. The inner side of the cross section of the second housing 21 has a second arc-shaped edge 211, and the shape and size of the second arc-shaped edge 211 are completely matched with the first arc-shaped edge 111. This matching design ensures the stability and smoothness of the tweeter 1 when rotating.

[0046] During the assembly process, the tweeter 1 is matched with the second arcuate edge 211 of the second housing 21 of the woofer 2 through the first arcuate edge 111 of the first housing 11. This match allows the tweeter 1 to be rotatably mounted on the woofer 2. The axis of rotation coincides with the centerline of curvature of the first arcuate edge 111 and the second arcuate edge 211, which ensures the accuracy and consistency of the rotation.

[0047] When the direction of the sound field needs to be adjusted, the user can directly rotate the tweeter 1. Due to the precise matching of the first arc edge 111 and the second arc edge 211, the tweeter 1 can rotate smoothly within a predetermined angle range. This rotation changes the direction of the tweeter 1, thereby adjusting the radiation direction of the high-frequency sound, and realizing flexible adjustment of the sound field.

[0048] The key reason for choosing the curved edge as the rotation mechanism is its simple structure and efficient adjustment. The curved design not only provides a smooth rotation experience, but also maintains stability at different angles. In addition, this design can minimize the acoustic interference that may occur during the rotation process, ensuring the stability of the sound quality.

[0049] It should be noted that if Figure 1 As shown, in order to further simplify the combination of the first shell 11 and the second shell 21 and prevent the first shell 11 from falling off the second shell 21, the top end of the second arcuate edge 211 is designed to be higher than the center of the first arcuate edge 111 and the bottom end of the second arcuate edge 211 is designed to be lower than the center of the first arcuate edge 111, so that the widest part of the first shell 11 can be confined within the second shell 21, so that the tweeter 1 can fit closely with the woofer 2; in addition, the first shell 11 and the second shell 21 have a certain elasticity, and the worker places the tweeter 1 above the woofer 2, and by applying downward force to press the tweeter 1, the first shell 11 of the tweeter 1 can be inserted into the second shell 21 of the woofer 2 to complete the assembly of the combined speaker, which has the advantage of convenient assembly.

[0050] The combined loudspeaker of the embodiment of the present application is rotatably connected by a tweeter 1 and a woofer 2 through a shell, so that the tweeter 1 can be rotatably adjusted on the woofer 2 to achieve adjustment of the relative directions of the high and low sound fields, allowing the user to accurately adjust the orientation of the tweeter 1 according to actual needs, providing great flexibility to adapt to different audio environment requirements, and the adjustment structure does not need to introduce additional electronic systems, reducing costs and potential signal interference; in addition, the first shell 11 on the tweeter 1 and the second shell 21 on the woofer 2 are tightly connected through the arc edge cooperation, which not only ensures the stability and accuracy of the rotation of the tweeter 1, but also maintains the compactness of the overall structure.

[0051] It should be noted that during assembly, the first shell 11 of the tweeter 1 is embedded in the groove at the top of the second shell 21 of the woofer 2 through its first arc-shaped edge 111. In order to reduce friction and ensure smooth rotation, a layer of silicone grease lubricant can also be applied between the two arc-shaped edges.

[0052] In some preferred embodiments, the outer periphery of the first housing 11 has a spherical first annular wall 112 , and the inner periphery of the second housing 21 has a spherical second annular wall 212 that fits the first annular wall 112 .

[0053] Specifically, the above design significantly expands the rotation adjustment range of the tweeter 1 by introducing a spherical annular wall structure between the first housing 11 and the second housing 21; the spherical annular wall structure allows the tweeter 1 to rotate in all directions on the woofer 2, and is no longer restricted by a plane or a simple arc structure. This design solves the problem of limited rotation adjustment range of the tweeter 1 in traditional combination speakers, and provides users with more flexible and precise sound field adjustment capabilities.

[0054] More specifically, if Figure 4 As shown, the outer periphery of the first shell 11 is designed as a spherical first annular wall 112, while the inner periphery of the second shell 21 is designed as a spherical second annular wall 212 that fits therewith. The two spherical annular walls form a spherical contact surface, allowing the tweeter 1 to slide and rotate freely on this spherical contact surface. Due to the characteristics of the spherical structure, the tweeter 1 can rotate in any direction, achieving 360° full-range adjustment; the design of this spherical structure not only expands the rotation range, but also provides a smoother and more stable rotation experience; the spherical contact surface can evenly distribute pressure, reduce friction and wear, and extend the service life of the combination speaker; in addition, the spherical structure can also maintain good sealing during rotation, which helps to maintain the stability of the acoustic performance.

[0055] More specifically, this free rotation adjustment design provides users with more sound field adjustment options. Users can accurately adjust the direction of the tweeter 1 according to factors such as scene layout, listening position, sound reflection, etc., so as to rotate the tweeter 1 to the optimal angle to cover a wider listening area.

[0056] It should be noted that the outer periphery has a spherical first annular wall 112, the inner periphery of the second shell 21 has a spherical second annular wall 212 that is in contact with the first annular wall 112, the cross-section of the first annular wall 112 corresponds to the first arcuate edge 111, and the cross-section of the second annular wall 212 corresponds to the second arcuate edge 211.

[0057] In some preferred embodiments, the first shell 11 and the second shell 21 are in the shape of long strips, the first shell 11 has first arcuate surfaces 113 on both sides corresponding to the first arcuate edges 111 , and the second shell 21 has second arcuate surfaces 213 on both sides corresponding to the second arcuate edges 211 .

[0058] Specifically, the above-mentioned design realizes the function of left and right tilt and rotation adjustment of the tweeter 1 on the woofer 2 by designing the first shell 11 and the second shell 21 to be long strips and providing corresponding arc surfaces on both sides. This design not only increases the flexibility of the speaker, but also enables the user to adjust the direction of the sound field according to actual needs, so as to obtain the best listening experience in different audio environments.

[0059] More specifically, if Figure 5 As shown, the long strip design of the first shell 11 and the second shell 21 provides enough space for the tweeter 1 and the woofer 2, so that they can be tilted and rotated in the long axis direction. The first shell 11 has first curved surfaces 113 on both sides corresponding to the first curved edges 111. This feature provides an axis of rotation and a support point for the tweeter 1. The second shell 21 has second curved surfaces 213 on both sides corresponding to the second curved edges 211. This feature cooperates with the first curved surfaces 113 to form a rotatable contact surface. The design of the first curved surface 113 and the second curved surface 213 allows the tweeter 1 to rotate smoothly on the woofer 2, while the long strip design ensures the stability of the rotation and a sufficient adjustment range, and can also meet the design requirements of the long strip combination speaker.

[0060] More specifically, the long strip design of the first housing 11 and the second housing 21 can adopt different length-to-width ratios to adapt to different application scenarios. For example, in a home theater system, a longer design can be adopted to provide a larger adjustment range; while in a car audio system, a relatively short design can be adopted to adapt to limited installation space.

[0061] In some preferred embodiments, there are multiple tweeters 1 , which are arranged and installed on the woofer 2 along the length direction of the second housing 21 .

[0062] Specifically, Figure 6 As shown, the above design allows different tweeters 1 to be independently oriented; specifically, multiple tweeters 1 are arranged along the length direction of the second housing 21, and each tweeter 1 can be independently tilted and rotated on the woofer 2. This design further increases the flexibility of the speaker. Since each tweeter 1 can be adjusted independently, the user can accurately adjust the orientation of each tweeter 1 according to different listening environments and needs. For example, in a long room, the tweeters 1 at different positions can be adjusted to different angles to ensure that the sound is evenly distributed throughout the space; secondly, this design improves the accuracy of the sound field control. By independently adjusting multiple tweeters 1, a more complex and sophisticated sound field can be created. In addition, this design of multiple tweeters 1 also increases the adaptability of the speaker. In different application scenarios, such as home theaters, recording studios, or car audio systems, users can adjust the orientation of the tweeters 1 according to specific needs to obtain the best sound effect. For example, in a home theater system, the central tweeter 1 can be directed straight ahead, while the tweeters 1 on both sides can be slightly tilted outward to create a wider sound field.

[0063] More specifically, the technical solution of the present application effectively solves the problem of adjusting the orientation of the tweeter 1 by installing multiple tweeters 1 with independently adjustable orientations on the woofer 2. This design not only improves the flexibility and adaptability of the speaker, but also enables it to better adapt to different audio environments and user needs. By allowing each tweeter 1 to be adjusted independently, users can accurately adjust the sound field according to factors such as room layout and listening position, thereby obtaining the best listening experience.

[0064] In some preferred embodiments, a conjugate transmission structure 3 is provided between two adjacent tweeters 1 so that the two adjacent tweeters 1 have the same deflection angle relative to the woofer 2 and opposite deflection directions.

[0065] Specifically, the present application introduces a conjugated transmission structure 3 to solve the problem of adjusting the orientation of adjacent tweeters 1. Specifically, multiple tweeters 1 are arranged and installed along the length direction of the woofer 2, which provides a basis for achieving independent orientation adjustment. Adjacent tweeters 1 are connected by a conjugated transmission structure 3, so that adjacent tweeters 1 can achieve symmetrical opposite orientations. When a tweeter 1 rotates, the adjacent tweeter 1 will rotate in the opposite direction due to the transmission action of the conjugated transmission structure 3.

[0066] More specifically, the conjugate transmission structure 3 and the rotatable installation of the tweeter 1 form a coordinated system. When the user adjusts the orientation of a tweeter 1, the conjugate transmission structure 3 will automatically drive the adjacent tweeter 1 to adjust symmetrically. This design not only simplifies the operation process, but also ensures the precise symmetry of the orientations of adjacent tweeters, thereby helping to form a more balanced and directional sound field, so that the orientation adjustment process of the tweeter 1 is equivalent to the adjustment process of the sound angle range of the superimposed sound field of multiple tweeters 1, which can ensure the balance and consistency of the sound field and avoid the asymmetry problem that may be caused by traditional manual adjustment.

[0067] In some preferred embodiments, Figure 7 As shown, the conjugate transmission structure 3 includes: a first connecting shaft 31, a first connecting rod 32, a second connecting rod 33 and a third connecting rod 34, one end of the first connecting rod 32 is fixed to the top of the woofer 2, the first connecting rod 32 is provided with a vertically extending straight groove, the first connecting shaft 31 is slidably installed on the straight groove, and both ends are respectively connected to one end of the second connecting rod 33 and one end of the third connecting rod 34, the other end of the second connecting rod 33 and the other end of the third connecting rod 34 are respectively hinged to two adjacent side surfaces of the tweeter 1 adjacent to each other.

[0068] Specifically, in this embodiment, when the user applies force to rotate a tweeter 1 connected to the second connecting rod 33, the second connecting rod 33 connected to the tweeter 1 swings, thereby driving the first connecting shaft 31 to move up and down in the straight groove, so that the first connecting shaft 31 drives the third connecting rod 34 to swing symmetrically opposite to the second connecting rod 33, thereby causing the tweeter 1 connected to the third connecting rod 34 to rotate in the opposite direction relative to the tweeter 1 connected to the second connecting rod 33. The adjustment process is convenient and simple, and can ensure that adjacent tweeters 1 can produce rotation behaviors with opposite rotation directions and consistent strokes, thereby ensuring the balance and consistency of the sound field, and avoiding the asymmetry problems that may be caused by traditional manual adjustment.

[0069] More specifically, in this embodiment, the number of tweeters 1 is preferably an even number.

[0070] In some preferred embodiments, the combination loudspeaker further comprises a first rotating member 4 , and the tweeter 1 and the woofer 2 are rotatably connected via the first rotating member 4 .

[0071] Specifically, the purpose of introducing the first rotating member 4 as a connecting member between the tweeter 1 and the woofer 2 in the combined loudspeaker of the embodiment of the present application is to enhance the structural strength between the tweeter 1 and the woofer 2 while ensuring the connection stability between the tweeter 1 and the woofer 2 under the premise of realizing the rotation connection by the cooperation of the first arcuate edge 111 and the second arcuate edge 211; the first rotating member 4 can be implemented in a variety of forms. For example, a ball hinge structure can be used to allow the tweeter 1 to rotate freely in multiple directions. Another way is to use a bearing structure to enable the tweeter 1 to rotate around a specific axis. It is also possible to consider using a flexible connector, such as a connector made of rubber or elastic material, which can ensure the stability of the connection and provide a certain degree of rotational freedom.

[0072] More specifically, the design of the first rotating member 4 needs to take into account the control of the rotational resistance. Too little rotational resistance may cause the position of the tweeter 1 to be unstable, while too much rotational resistance may affect the flexibility of adjustment. Therefore, an appropriate friction mechanism or damping device can be added to the first rotating member 4 to achieve an ideal rotation effect.

[0073] More specifically, in an embodiment in which the outer periphery of the aforementioned first shell 11 has a spherical first annular wall 112, the first rotating member 4 is preferably a ball, and in an embodiment in which the first shell 11 has first arcuate surfaces 113 corresponding to the first arcuate edges 111 on both sides, the first rotating member 4 is preferably a horizontally arranged cylindrical shaft.

[0074] More specifically, if Figure 2 As shown, a first support member 41 is connected to the bottom of the tweeter 1, and a second support member 42 is connected to the top of the woofer 2. The first support member 41 is rotatably connected to the second support member 42 via a first rotating member 4, wherein the bottom surface of the first support member 41 and the top surface of the second support member 42 are both in close contact with the first rotating member 4.

[0075] In some preferred embodiments, the bottom of the tweeter 1 further includes a first yoke 12; The tweeter 1 and the woofer 2 are sealed and enclosed to form a transition cavity 5 . The tweeter 1 has a first cavity 13 . The first yoke 12 has a plurality of air holes 121 connecting the first cavity 13 and the transition cavity 5 .

[0076] Specifically, the present application sets a first yoke 12 at the bottom of the tweeter 1, and opens an air hole 121 on the first yoke 12 to connect the first cavity 13 inside the tweeter 1 and the transition cavity 5 between the high and low frequency units 2. Since the temperature of the voice coil will rise sharply during the sound production of the tweeter 1, the combination speaker of the embodiment of the present application sets the air hole 121 on the first yoke 12 to allow the gas that passes through the first cavity 13 and the transition cavity 5, so that the gas in the first cavity 13 that is heated by the heat of the voice coil can be quickly transferred to the transition cavity 5 through the air hole 121 under the action of vibration for heat dissipation. This structure not only improves the efficiency of the speaker, but also may improve the quality of the sound, making the transition between the high and low frequencies more natural and coordinated, and can also enhance the heat dissipation effect of the tweeter 1.

[0077] More specifically, if Figure 2 As shown, in this embodiment, the tweeter 1 also includes a first frame 14, a first magnet 15, a first voice coil 16, a first washer 17 and a first diaphragm 18, wherein the first diaphragm 18, the first frame 14 and the first yoke 12 which are sealed and connected in sequence enclose a first cavity 13, the first magnet 15 is fixed on the first yoke 12, the first washer 17 is fixed on the top of the first magnet 15, and a first gap is provided between the outer periphery of the first magnet 15 and the first yoke 12, one end of the first voice coil 16 is fixed on the diaphragm, and the other end is located in the first gap; the first shell 11 is sealed and connected to the first frame 14.

[0078] It should be noted that, in the embodiments of the present application, the sealed connection refers to a sealed fixed connection using glue or snap fasteners.

[0079] More specifically, if Figure 2 As shown, in this embodiment, the woofer 2 also includes a second yoke 22, a second frame 24, a second magnet 25, a second voice coil 26, a second washer 27 and a second diaphragm 28, wherein the second diaphragm 28, the second frame 24 and the second yoke 22 which are sealed and connected in sequence enclose a second cavity 23, the second magnet 25 is fixed on the second yoke 22, the second washer 27 is fixed on the bottom of the second magnet 25, a second gap is provided between the outer periphery of the second magnet 25 and the second yoke 22, one end of the second voice coil 26 is fixed on the second diaphragm 28, and the other end is located in the second gap; the second shell 21 is sealed and connected to the second frame 24.

[0080] More specifically, in this embodiment, the connecting area formed by the transition cavity 5 and the first cavity 13 is isolated from the second cavity 23, which can ensure that the tweeter 1 and the woofer 2 do not interfere with each other when working together.

[0081] More specifically, the combination speaker of the embodiment of the present application can accurately adjust the amount of sound pressure transmission by controlling the number, size and distribution of the air holes 121, thereby optimizing the acoustic performance of the entire speaker system; in the embodiment of the present application, the air holes 121 are preferably multiple and evenly distributed around the first magnet 15, which can effectively improve the uniformity and stability of the treble.

[0082] In some other embodiments, since the woofer 2 requires a larger back cavity volume to produce sound than the tweeter 1, if the original space size of the second cavity 23 is not sufficient to support the woofer 2 to produce sound, a through-hole structure (not shown in the icon) can be added to the second yoke 22 or the second frame 24 to allow the transition cavity 5 and the second cavity 23 to form a connecting area, which is isolated from the first cavity 13; this embodiment indirectly expands the back cavity volume of the woofer 2 by utilizing the transition cavity 5, so that the second cavity 23 can be designed to be smaller, so that the combined speaker of the embodiment of the present application has the advantage of a small size.

[0083] In some preferred embodiments, Figure 8 As shown, the woofer 2 also includes a second yoke 22, a second frame 24, a second magnet 25, a second voice coil 26, a second washer 27 and a second diaphragm 28. The difference between the structural composition of the woofer 2 and the traditional woofer 2 is that the second washer 27, the second magnet 25, the second yoke 22, the second frame 24 and the second diaphragm 28 are sealed and connected in sequence to enclose a second cavity 23 isolated from the transition cavity 5; the second magnet 25 and the second yoke 22 are connected in the middle to form a second groove 29, and the middle inner side of the tweeter 1 is located in the second groove 29.

[0084] Specifically, in this embodiment, the second cavity 23 is formed by the second washer 27, the second magnet 25, the second yoke 22, the second frame 24 and the second diaphragm 28 being sealed and connected in sequence, and a second groove 29 connected to the transition cavity 5 is generated, and the second groove 29 provides an installation space for the tweeter 1, making the internal space of the combination speaker more compact. The inner middle part of the tweeter 1 is designed to be located in the second groove 29. This design makes full use of the internal space of the combination speaker. By transforming the second yoke 22 and the second magnet 25 into a hollow through structure, a second groove 29 is formed to avoid the installation of the inner middle part of the tweeter 1; through this design, the tweeter 1 and the woofer 2 form a compact whole while maintaining their respective independence and functionality. This structure not only solves the installation problem and makes the speaker more refined, but also may bring about an improvement in acoustic performance, such as reducing sound wave interference and optimizing the sound field. In addition, this design may also improve the overall stability and durability of the speaker.

[0085] More specifically, if Figure 8As shown, the middle inner side of the tweeter 1 , namely the lower half of the first magnet 15 and the lower half of the first yoke 12 , are suspended in the second groove 29 .

[0086] More specifically, in an embodiment including the first rotating member 4, as Fig. 9 As shown, the first support member 41 is fixed to the bottom of the first yoke 12 , and the second support member 42 is fixed to the top of the second washer 27 and is located in the second groove 29 .

[0087] In some preferred embodiments, one side of the first shell 11 has a plurality of adjustment slots 114 equidistantly arranged along the extension direction of the first arc-shaped edge 111 , and the inner side of the second shell 21 has an elastic snap block 214 that can snap fit with the adjustment slots 114 to limit the deflection angle of the first shell 11 .

[0088] Specifically, a plurality of adjustment slots 114 provided on one side of the first shell 11 are equidistantly distributed along the extension direction of the first arc-shaped edge 111. This distribution ensures that the tweeter 1 can be evenly adjusted within a certain angle range. The number and spacing of the adjustment slots 114 can be designed according to actual needs. For example, 5-10 adjustment slots 114 can be provided, and the angle interval between each slot can be 5°-15°. The elastic buckle block 214 on the inner side of the second shell 21 is a key component that cooperates with the adjustment slot 114. The elastic buckle block 214 can be made of elastic material, for example, elastic plastic or metal shrapnel. The shape and size of the elastic buckle block 214 should match the adjustment slot 114 to ensure the stability and reliability of the buckle fit.

[0089] More specifically, when the user needs to adjust the deflection angle of the tweeter 1, the user only needs to gently rotate the tweeter 1, and the elastic buckle block 214 will engage with different adjustment slots 114, thereby fixing the tweeter 1 at a specific angle. This mechanism design not only ensures the accuracy and stability of the adjustment, but also takes into account the convenience of operation. In this way, the user can flexibly adjust the sound direction of the tweeter 1 according to actual needs, thereby optimizing the sound field effect and improving the listening experience.

[0090] More specifically, combined with the feature that the tweeter 1 is rotatably mounted on the woofer 2 by cooperating with the first arc edge 111 and the second arc edge 211, the adjustment slot 114 and the elastic buckle block 214 of the present application are designed to improve the adjustment accuracy and stability. This combination not only realizes the step-by-step enhancement of the rotation function of the tweeter 1, but also provides accurate angle positioning capability, so that the user can adjust the direction of the sound field more accurately.

[0091] In some preferred embodiments, the first housing 11 further comprises a limiting slot 115 arranged along the extending direction of the first arc-shaped edge 111 , and the second housing 21 comprises a clamping strip 215 slidably connected to the limiting slot 115 .

[0092] Specifically, the second housing has a clip strip 215 slidably connected to the limiting slot 115 , which can further improve the accuracy and stability of adjustment and prevent the first housing 11 and the second housing 21 from loosening or shifting, resulting in the elastic buckle block 214 being unable to enter the adjustment slot 114 .

[0093] In some preferred embodiments, the elastic buckle block 214 includes a clamping head 2141 for clamping into the adjusting slot 114 and an elastic member 2142 with two ends respectively connecting the clamping head 2141 and the second housing 21 .

[0094] Specifically, the elastic member 2142 is a spring or a sponge. In the embodiment of the present application, a spring is preferred.

[0095] More specifically, if Fig.11 As shown, the clamp 2141, the elastic member 2142, and the second housing 21 are preferably connected as one piece, so as to further improve the accuracy and stability of the adjustment.

[0096] In a second aspect, some embodiments of the present application further provide an electronic device, comprising the combination speaker provided in the first aspect.
