Description

Technical Field

[0001] This application relates to the field of loudspeaker technology, and in particular to dual-drive, dual-sided loudspeaker devices. Background Technology

[0002] In the field of audio technology, bifacial loudspeaker devices have attracted much attention due to their unique bifacial sound emission characteristics. Traditional bifacial loudspeaker devices typically employ a design using two voice coils with a shared magnetic circuit module. This design divides the internal structure of the bifacial loudspeaker device into two independent resonant spaces via the magnetic circuit module, with each voice coil residing in one of these spaces. However, this separation design has a significant problem: the two resonant spaces are not connected, which leads to limitations in the sound quality performance of bifacial loudspeaker devices.

[0003] Specifically, because the two resonant spaces are independent and unconnected, sound cannot effectively resonate and superimpose between them during propagation, thus limiting the improvement of sound quality. Therefore, traditional two-sided speaker devices often perform poorly in low frequencies, mid frequencies, and vocal clarity. To improve this, an intuitive solution is to increase the size of the resonant spaces, hoping to enhance the resonance effect and improve sound quality. However, this approach significantly increases the size of the two-sided speaker device, making it bulky and unsuitable for the current market demanding slim designs in electronic devices.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0042] See Figures 1 to 3 , Figures 1 to 3 The structure, cross-section, and exploded view of a dual-drive dual-sided loudspeaker device according to one embodiment of this application are shown respectively.

[0043] See Figure 2An embodiment of this application provides a dual-drive, dual-sided loudspeaker device, comprising: a magnetic carrier plate 1, a magnetic circuit module 2, a voice coil 3, an elastic component 4, and a vibration sound-generating component 5.

[0044] Specifically, two adjacent magnetically conductive carrier plates 1 are provided. Each magnetically conductive carrier plate 1 includes a base plate 10 and two side magnetically conductive elements 11. The two side magnetically conductive elements 11 are respectively disposed on both sides of the base plate 10, located on the upper and lower sides of the base plate 10. The two side magnetically conductive elements 11 are integrally formed with the base plate 10 to form an H-shaped structure, which not only enhances the guidance of the magnetic field but also improves the stability and strength of the structure.

[0045] Furthermore, the speaker also includes four magnetic circuit modules 2, with each pair of magnetic circuit modules 2 positioned on the upper and lower sides of a base plate 10, respectively. The magnetic circuit modules 2 are responsible for generating a stable magnetic field to power the vibration of the voice coil 3.

[0046] Furthermore, the speaker also includes four voice coils 3, each voice coil 3 being disposed between a magnetic circuit module 2 and two side-guided magnetic components 11, with each voice coil 3 surrounding a magnetic circuit module 2 at intervals. This arrangement ensures that the voice coils 3 are subjected to uniform force in the magnetic field, thereby improving the sound output.

[0047] See Figure 3 One embodiment of this application provides a dual-drive, dual-sided loudspeaker device, which further includes four sets of elastic components 4. Each set includes two elastic elements 40, which are respectively disposed on both sides of a voice coil 3. The elastic components 4 are used to support the voice coil 3 and limit its vibration range, ensuring the stable movement of the voice coil 3, while preventing damage caused by excessive vibration.

[0048] Furthermore, the sound-generating device also includes two vibration-generating components 5, which are respectively disposed on one side of two adjacent magnetic carrier plates 1. One vibration-generating component 5 has a first accommodating space 50, in which two adjacent magnetic circuit modules 2, two voice coils 3 and four elastic components 4 are disposed; the other vibration-generating component 5 has a second accommodating space 51 that communicates with the first accommodating space 50, in which two adjacent magnetic circuit modules 2, two voice coils 3 and four elastic components 4 are disposed.

[0049] Furthermore, the first accommodating space 50 and the second accommodating space 51 are interconnected through the front and rear ends of the magnetic carrier plate 1, ensuring that the air between them can circulate and forming a double-sided sound-generating structure, thereby producing and enhancing the effect of three-dimensional resonance sound.

[0050] As described above, the dual-drive, dual-sided speaker system achieves bidirectional sound output through the structural layout of the magnetic carrier plate, magnetic circuit module, voice coil, and elastic components, enhancing the immersive and stereo sound. Furthermore, the H-shaped magnetic carrier plate makes the entire speaker system compact, facilitating installation and use in limited spaces. The optimized layout of the magnetic circuit module and voice coil, along with the use of elastic components for stable support, collectively ensures the high-quality sound of the speaker system.

[0051] In one embodiment, the overall height of the two side-guided magnetic components 11 is greater than or equal to the overall height of the two adjacent magnetic circuit modules 2, ensuring that the magnetic circuit modules 2 are completely located between the side-guided magnetic components 11, thereby optimizing the distribution of the magnetic field and improving the sound quality.

[0052] Combination Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of the magnetic carrier plate 1 provided in one embodiment of this application. In some embodiments, the base plate 10 and the two side magnetic conductors 11 have a longitudinal structure, and the extension length of the base plate 10 is greater than the extension length of the two side magnetic conductors 11, so that the magnetic carrier plate 1 has sufficient space in the longitudinal direction to accommodate the magnetic circuit module 2, the voice coil 3 and the elastic component 4, while ensuring the compactness of the structure.

[0053] In one embodiment, two arc-shaped bosses 100 are respectively provided on both sides of the base plate 10 extending in the direction of extension, and the two bosses 100 extend from the two side magnetic guides 11. The design of the bosses 100 not only enhances the strength of the base plate 10, but also provides additional support points, which helps to maintain the stability and durability of the speaker. In this embodiment, the bosses 100 have a semi-circular structure, and the structure and shape of the bosses 100 can be adaptively adjusted according to specific usage requirements.

[0054] In one embodiment, the extension length of the two bosses 100 is less than or equal to the overall length of the magnetic circuit module 2, ensuring that the bosses 100 do not interfere with the normal operation of the magnetic circuit module 2 and the voice coil 3, while optimizing the overall structure of the speaker.

[0055] Combination Figure 3 As shown, Figure 3 This is an exploded view of a dual-drive, dual-sided speaker device provided in one embodiment of this application. In some embodiments, each magnetic circuit module 2 includes a magnetic body 21 and a magnetic guide plate 22. The magnetic body 21 is disposed on one side surface of the base plate 10, and the magnetic guide plate 22 is disposed on the side of the magnetic body 21 away from the base plate 10, so that the magnetic field can act more effectively on the voice coil 3, thereby improving the sound quality.

[0056] In one embodiment, the two side magnetic guides 11 are plate-shaped structures, and their height is higher than that of the magnetic body 21 and the magnetic plate 22, ensuring that the magnetic circuit module 2 is completely located between the side magnetic guides 11, thereby optimizing the magnetic field distribution. At the same time, the side magnetic guides 11 also guide the magnetic field, making the magnetic field act more concentrated on the voice coil 3.

[0057] In this embodiment, parameters such as the size of the magnetic carrier plate 1, the specifications of the magnetic circuit module 2 (including the magnetic body 21 and the magnetic carrier plate 22), the specifications of the voice coil 3, and the elastic coefficient of the elastic component 4 can be adjusted according to specific needs to achieve the best sound performance. In addition, the height of the side magnetic guide 11 can also be adjusted according to the actual situation to ensure that the magnetic circuit module 2 is completely located between it and to optimize the distribution of the magnetic field.

[0058] Combination Figure 1 , Figure 2 As shown, Figure 1 , Figure 2 These are schematic diagrams of the structure and cross-section of a dual-drive, dual-sided loudspeaker device provided in one embodiment of this application. In some embodiments, the loudspeaker device includes a first vibration-generating component 52 and a second vibration-generating component 53. The first vibration-generating component 52 includes a first support 521 and a first diaphragm 522, and the second vibration-generating component 53 includes a second support 531 and a second diaphragm 532.

[0059] Specifically, the first bracket 521 is disposed on both sides above the two side magnetic components 11, and the first diaphragm 522 is disposed on the side of the first bracket 521 away from the side magnetic components 11 and connected to the first voice coil 3; the second bracket 531 is disposed on both sides below the two side magnetic components 11, and the second diaphragm 532 is disposed on the side of the second bracket 531 away from the side magnetic components 11 and connected to the second voice coil 3, so that the speaker can emit sound from both sides, enhancing the immersiveness and stereo effect of the sound.

[0060] Combination Figure 6 As shown, Figure 6 This is a schematic diagram of the structure of the first bracket 521 and the second bracket 531 provided in one embodiment of this application. In some embodiments, the two side walls of the inner side of the first bracket 521 or the second bracket 531 are provided with guide grooves 525, and the two side magnetic conductors 11 are respectively embedded in the guide grooves 525 provided in the inner side walls of the first bracket 521 or the second bracket 531 to realize the fixed installation of the magnetic carrier plate 1 and improve stability.

[0061] In one embodiment, the first bracket 521 includes a first docking structure 523, and the second bracket 531 includes a second docking structure 533. The first docking structure 523 and the second docking structure 533 are opposite to each other and are connected and fixed to each other to form an integral structure, thereby enhancing the stability of the speaker.

[0062] In one embodiment, the first mating structure 523 and the second mating structure 533 can be either protrusions or slots. Specifically, the first mating structure 523 is a protrusion and the second mating structure 533 is a slot, or the first mating structure 523 is a slot and the second mating structure 533 is a protrusion. The protrusion fits into the slot, achieving a stable connection.

[0063] In one embodiment, the first bracket 521 has a protruding fixing post 524 on the side near the second bracket 531, and the second bracket 531 has a fixing hole 534 on the side near the first bracket 521. The fixing post 524 passes through the fixing hole 534, further enhancing the connection stability between the first bracket 521 and the second bracket 531.

[0064] In one embodiment, a gap exists between the first support 521 and the second support 531, which helps to reduce mutual interference during vibration and improve sound quality.

[0065] Combination Figure 3 As shown, Figure 3 This is an exploded view of a dual-drive, dual-sided loudspeaker device provided in one embodiment of this application. In some embodiments, one side of each pair of elastic members 40 is connected to both sides of a voice coil 3, and the other side of each pair of elastic members 40 is connected to a first support 521, for supporting and limiting the vibration range of the voice coil 3 and ensuring the stable movement of the voice coil 3.

[0066] Similarly, one side of each pair of elastic elements 40 is connected to both sides of a voice coil 3, and the other side of each pair of elastic elements 40 is connected to the second bracket 531, which can also support and limit the vibration range of the voice coil 3 and ensure the stable movement of the voice coil 3.

[0067] Combination Figure 5 As shown, Figure 5This is a schematic diagram of the structure of the elastic element 40 provided in one embodiment of this application. In some embodiments, the elastic element 40 includes an arc-shaped first contact surface 401 and a second contact surface 402. The first contact surface 401 is connected to both sides of the voice coil 3, and the second contact surface 402 is connected to the first support 521 or the second support 531, so that the elastic element 40 can better adapt to the vibration of the voice coil 3 and reduce energy loss during vibration. In this embodiment, the elastic element 40 is a fan-shaped wave, and the first contact surface 401 and the second contact surface 402 on both sides of the wave are respectively connected to the first support 521 or the second support 531.

[0068] In one embodiment, the elastic element 40 has a wave-like structure. The wave-like structure provides better elasticity and restoring force, making the voice coil 3 more stable during vibration. At the same time, the arcuate extension length of the first contact surface 401 is less than the arcuate extension length of the second contact surface 402, allowing the elastic element 40 to distribute stress more evenly when under force, thus extending its service life.

[0069] Combination Figure 3 As shown, Figure 3 This is an exploded view of a dual-drive, dual-sided loudspeaker device provided in one embodiment of this application. In some embodiments, it further includes four sets of electrical connectors 6, wherein two sets of electrical connectors 6 are respectively disposed on the first bracket 521 and exposed on the outer surface of the first bracket 521, and electrically connected to two of the voice coils 3; the other two sets of electrical connectors 6 are disposed on the second bracket 531 and exposed on the outer surface of the second bracket 531, and electrically connected to the other two voice coils 3. In this embodiment, the electrical connectors 6 can be welded, plugged in, or other reliable connection methods to ensure a stable connection with the voice coils 3.

[0070] In this embodiment, an external power source supplies current to the voice coil 3 through the electrical connector 6, and the voice coil 3 generates a magnetic field under the influence of the current. Therefore, the magnitude and direction of the magnetic field generated by the voice coil 3 can be changed by altering the magnitude of the current supplied to the voice coil 3. The magnetic field of the voice coil 3 interacts with the magnetic field of the magnetic circuit module 2, causing the voice coil 3 to vibrate orthogonally to the direction of the current. The voice coil 3 drives the first diaphragm 522 or the second diaphragm 532 to vibrate, thereby producing sound.

[0071] In this embodiment, the dual-drive dual-sided speaker device comprises two independent drive units formed by a magnetic carrier plate 1, a magnetic circuit module 2, a voice coil 3, an elastic component 4, and a vibration-generating component 5. One drive unit includes a magnetic carrier plate 1, two magnetic circuit modules 2, two voice coils 3, two sets of elastic components 4, and two vibration-generating components 5, forming a first and second speaker section with dual-sided sound generation. The other drive unit includes a magnetic carrier plate 1, two magnetic circuit modules 2, two voice coils 3, two sets of elastic components 4, and two vibration-generating components 5, forming a third and fourth speaker section with dual-sided sound generation. Furthermore, the first accommodating space 50 and the second accommodating space 51 in this embodiment are two resonant cavities of the dual-drive dual-sided speaker device, which are interconnected. This increases the volume of the resonant cavities of the dual-sided speaker device without increasing the overall volume, effectively improving the stereo sound quality of the dual-drive dual-sided speaker device.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
