Description

Technical Field

[0001] This utility model relates to the field of diaphragm speaker technology, specifically to a planar diaphragm speaker with petal-shaped circuitry. Background Technology

[0002] A planar magnetic speaker is a device specifically designed for audio output. Driven by an electromagnetic field, it causes a planar diaphragm to vibrate in conjunction with a magnet, emitting sound waves. This converts electrical signals into audible sound, achieving efficient audio signal conversion. This design not only improves sound clarity and fidelity but also makes the speaker more stable and reliable during operation.

[0003] Most existing planar diaphragm speakers consist of a diaphragm and a ring-shaped or strip-shaped magnet. However, due to the high hardness and low toughness of magnets, they are prone to breakage under high-frequency vibration or external impact, thus affecting the speaker's lifespan and sound quality. Therefore, this invention proposes a planar diaphragm speaker with miniaturized magnets and a petal-shaped circuit. Summary of the Invention

[0004] This invention provides a planar diaphragm speaker with a petal-shaped circuit, which solves the problem of magnets being easily broken when subjected to high-frequency vibration or external impact through a magnet fragmentation design.

[0005] The objective of this utility model is achieved through the following means:

[0006] A planar diaphragm speaker with a petal-shaped circuit includes a diaphragm having a plurality of partitions, each partition having at least one magnet.

[0007] Furthermore, the other side of the diaphragm is symmetrically provided with several partitions and the magnet.

[0008] Furthermore, the magnets are arranged in multiple concentric rings along the center of the diaphragm.

[0009] Furthermore, the two adjacent partitions are fitted together.

[0010] Furthermore, the diaphragm includes a diaphragm sheet and a conductive coil corresponding to the magnet, and the conductive coils of the plurality of partitions are interconnected.

[0011] Furthermore, a fixing bracket is fitted on the outer side of the diaphragm, and the diaphragm is connected to the fixing bracket through a suspension edge.

[0012] Furthermore, a plurality of conductive lines are installed on the fixed bracket, and the conductive coils are interconnected through the conductive lines.

[0013] Furthermore, the suspension edge is provided with a lead groove that mates with the conductive coil.

[0014] Furthermore, the lead groove is S-shaped.

[0015] The beneficial effects of this invention are as follows: By fragmenting the ring magnet, the magnet's impact resistance is improved, effectively reducing the risk of breakage during high-frequency vibration or external impact, thus enhancing the speaker's durability and sound quality stability. Furthermore, the smaller magnet pieces allow for flexible adjustment of the magnet layout according to different coils, significantly improving magnetic field utilization. Simultaneously, by optimizing the layout of the conductive coils and increasing diaphragm strength, vibration consistency is improved while extending the effective length of the conductive coils, thereby increasing the force generated by the conductive coils in the magnetic field and enhancing the speaker's sensitivity.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] Example 1:

[0027] In this embodiment, refer to Figure 1 - Figure 4 The present invention relates to a planar diaphragm speaker with a petal-shaped circuit, comprising a diaphragm 1, wherein the diaphragm 1 has several partitions 2, and each partition 2 has at least one magnet 3. Through partition 2 design, and by replacing the overall magnet 3 with multiple smaller magnets 3 according to the partitions 2, the impact resistance of the magnets 3 is improved, thereby dispersing stresses from high-frequency vibrations and external impacts. This avoids breakage caused by excessive stress concentration on the magnets 3, improving the speaker's durability and sound quality stability. The magnets 3 in each partition 2 cooperate with the corresponding diaphragm 1 to complete sound wave transmission, ensuring that each partition 2 can respond to frequency changes, optimizing the sound field distribution, reducing distortion, and improving overall sound performance.

[0028] The other side of the diaphragm 1 is symmetrically arranged with several partitions 2 and magnets 3. Through the double-sided symmetrical design, the electromagnetic forces on both sides of the diaphragm 1 are opposite in direction but coincide in force, so that the diaphragm 11 is subjected to uniform force, suppressing local deformation and segmented vibration, eliminating mid-to-high frequency distortion, and optimizing audio output effect.

[0029] The two adjacent partitions 2 are fitted together. This allows the conductive coils 12 to have gaps between them while remaining adjacent to each other, thus making the magnetic flux directions of the adjacent partitions 2 complementary, forming a balanced magnetic field distribution. This further improves the dynamic response range of the diaphragm 1, ensures accurate transmission of audio signals, reduces energy loss, and enhances the purity and layering of the overall sound effect.

[0030] The diaphragm 1 includes a diaphragm 11 and conductive coils 12 corresponding to magnets 3. The conductive coils 12 of several sections 2 are interconnected. The conductive coils 12 are fixedly mounted on the diaphragm 11 and cooperate with the magnets 3 to precisely control the vibration of the diaphragm 1. By passing current through the conductive coils 12 to generate electromagnetic force, the diaphragm 11 is driven to cooperate with the magnets 3, converting the electrical signal into the mechanical vibration of the diaphragm 11, thereby achieving accurate reproduction of the audio signal.

[0031] In this embodiment, a four-zone design is adopted. The magnets 3 are arranged in multiple concentric rings along the center of the diaphragm 1, thereby ensuring uniform magnetic force in each zone 2, effectively reducing magnetic interference and improving sound clarity. Each zone 2 is equipped with a conductive coil 12 corresponding to the magnet 3. The conductive coils 12 form fan-shaped loops within the zone 2, thereby making full use of the zone 2 layout, improving circuit utilization, and increasing the effective circuit length of the conductive coils 12. According to the principle of F=BLT, the extended conductive coils 12 can enhance the force generated in the magnetic field, thereby enhancing the speaker's sensitivity. In addition, the optimized conductive coils 12 can also enhance the strength of the diaphragm 11, improving the consistency of diaphragm 11 vibration, reducing sound quality loss caused by uneven vibration, and ensuring delicate and balanced sound effects.

[0032] Furthermore, the fan-shaped ring circuit improves the support strength of the diaphragm 11, ensuring its consistency during vibration and guaranteeing a purer audio output. Simultaneously, the optimized layout of the conductive coil 12 effectively reduces resistance and improves current transmission efficiency, further enhancing the speaker's response speed and dynamic range, resulting in a more delicate and realistic sound.

[0033] A fixing bracket 13 is fitted around the outer side of the diaphragm 11, and the diaphragm 11 is connected to the fixing bracket 13 via a suspension edge 14. The fixing bracket 13 is used to connect and cooperate with the speaker, thereby fixing the diaphragm 11 in the speaker cavity and ensuring the stable operation of the diaphragm 1. The suspension edge 14 can be made of silicone, rubber, or other highly elastic materials, giving the diaphragm 11 a certain amount of elastic expansion and contraction space, thereby increasing the amplitude and air thrust, and thus improving the dynamic range and mid-low frequency performance of the audio output. The design of the suspension edge 14 not only improves the stability of the diaphragm 1, but also reduces mechanical wear caused by vibration and extends its service life.

[0034] Several conductive lines 15 are mounted on the fixed bracket 13, and the conductive coils 12 are interconnected through the conductive lines 15. The conductive lines 15 are made of highly conductive materials to ensure lossless signal transmission. By connecting different conductive lines 15 to the conductive coils 12 in different zones 2, independent or combined control of zones can be achieved, flexibly adjusting the audio output characteristics to meet diverse needs.

[0035] The suspension edge 14 is provided with a lead groove 141 that mates with the conductive coil 12. In this embodiment, the lead groove 141 is S-shaped. The S-shaped lead groove 141 makes the lead-out portion of the conductive coil 12 arc-shaped, thereby reducing local stress concentration, further suppressing split vibration, ensuring that the lead wire is not easily broken during long-term use, and improving the durability and reliability of the diaphragm 1.

[0036] The beneficial effects of this invention are as follows: By fragmenting the ring magnet 3, the impact resistance of the magnet 3 is improved, thereby effectively reducing the risk of breakage of the magnet 3 under high-frequency vibration or external impact, and improving the durability and sound quality stability of the speaker. Furthermore, the smaller magnet 3 allows for flexible adjustment of the magnet layout according to different coils, significantly improving magnetic field utilization. Simultaneously, by optimizing the layout of the conductive coil 12, the diaphragm strength is increased, improving vibration consistency while extending the effective length of the conductive coil 12, thereby increasing the force generated by the conductive coil 12 in the magnetic field and enhancing the speaker's sensitivity.

[0037] Example 2:

[0038] like Figure 5 - Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the conductive coils 12 are arranged around the edge of the partition 2 and gradually contract inward, with the conductive coils 12 of several partitions 2 interconnected. Magnets 3 are evenly distributed along the edge of the partition 2 and correspondingly arranged with the conductive coils 12 to ensure a uniform magnetic field distribution, thereby improving the uniformity and stability of sound quality. Furthermore, the conductive coils 12 arranged around the edge of the partition 2 can support the diaphragm 11, increasing the rigidity of the diaphragm 11. This prevents unnecessary deformation of the diaphragm 11 during operation, further improving the purity and stability of sound quality.

[0039] One end of the mounting bracket 13 is provided with a solder joint for connection to the conductive coil 12. The solder joint enables a reliable connection between the conductive coil 12 and external devices, thereby allowing the diaphragm 1 to efficiently receive audio signals and convert them into high-quality audio output.
