Description

Technical Field

[0001] This invention relates to the field of loudspeaker technology, specifically to a high-performance loudspeaker with an irregularly shaped voice coil. Background Technology

[0002] Consumer electronics products have been trending towards thinner and lighter designs in recent years, which has led to increasingly smaller speaker sizes and higher performance requirements. Speaker size and performance are directly proportional, as exemplified by the high-power, high-amplitude speaker disclosed in CN215818610U. These speakers all use traditional ring-shaped voice coils. Due to the increasing demand for small-sized, high-performance speakers, traditional voice coil speakers are no longer sufficient to meet these requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a high-performance loudspeaker with an irregularly shaped voice coil to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a high-performance loudspeaker with an irregular voice coil, comprising a magnetic circuit, a frame, a voice coil and a diaphragm assembly, wherein the voice coil comprises N interconnected units, each unit being U-shaped and forming two ends, adjacent ends of two adjacent units being connected, the voice coils being symmetrically arranged, and the value of N being greater than or equal to 4.

[0005] Furthermore, the value of N is 4, there is a height difference between the two ends of the monomer, and the included angles formed between the single monomer and the two monomers on both sides are acute and obtuse angles, respectively.

[0006] Furthermore, the value of N is 4, and the included angle between any two adjacent monomers is 90°.

[0007] Furthermore, the value of N is 8, and the included angle between any two adjacent monomers is 45°.

[0008] Furthermore, the magnetic circuit includes pole pieces, a central magnet, outer magnets, and a magnetic cover. The magnetic cover has a first groove, the shape of which is consistent with the orthographic projection shape of the voice coil. Multiple outer magnets are distributed generally along the outer edge of the first groove. The central magnet is disposed along the inner edge of the first groove. The pole pieces are stacked on the central magnet and form a gap with the outer magnets to accommodate the voice coil.

[0009] Furthermore, the electrode includes four handles, each of which is inserted into a single monomer.

[0010] Furthermore, there is a gap between two adjacent magnets to accommodate the FPC, which is connected to the unit.

[0011] Furthermore, the diaphragm assembly includes a dome and a diaphragm disposed around the dome. A first protrusion is provided on the dome, the shape of which is consistent with the orthographic projection shape of the voice coil and is connected to the voice coil.

[0012] Furthermore, the frame includes an outer frame and a partition disposed inside the outer frame. The partition is disposed above the magnetic circuit and has a first opening for accommodating the voice coil.

[0013] The present invention has the following beneficial effects: This invention, through the structure of an irregularly shaped voice coil and corresponding components, can increase the length of the coil or reduce the magnetic gap without changing the volume of the loudspeaker, thereby increasing the overall loudness of the loudspeaker; at the same time, it improves the voice coil's support for the dome, resulting in better high-frequency response. Attached Figure Description

[0014] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0015] Figure 1 This is a schematic diagram of a high-performance loudspeaker with an irregularly shaped voice coil, as described in Example 1. Figure 2 for Figure 1 Partial diagram of the explosion; Figure 3 for Figure 1 A complete diagram of the explosion. Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1 like Figures 1-3 In this embodiment, the high-performance loudspeaker with the irregular voice coil is mainly composed of a magnetic circuit 20, a frame 50, a voice coil 10, and a diaphragm assembly 40. Sound is generated by the coordinated vibration of the magnetic circuit 20, the voice coil 10, and the diaphragm assembly 40.

[0018] The voice coil 10 includes N interconnected units 11. Each unit 11 is U-shaped and has two ends. The adjacent ends of two adjacent units 11 are connected. The voice coil 10 is symmetrically arranged. The value of N is greater than or equal to 4, and is usually an even number. For example, if the value of N is 4, there is a height difference between the two ends of each unit 11, that is, the two stems of the U-shape are of different lengths. The included angles formed between a single unit 11 and the two units 11 on its sides are acute and obtuse, respectively. That is, the voice coil 10 forms an X-shaped structure on the orthographic projection. In this case, the length of the coil can be increased while keeping the number of coil turns the same, or the number of coil layers can be reduced while keeping the coil length the same, thereby reducing the magnetic gap. Both of these methods can improve the performance of the loudspeaker.

[0019] Correspondingly, the magnetic circuit 20 includes pole pieces 21, a central magnet 22, outer magnets 23, and a magnetic cover 24. The magnetic cover 24 is provided with a first groove 241, the shape of which is consistent with the orthographic projection shape of the voice coil 10. A plurality of outer magnets 23 are distributed along the outer edge of the first groove 241. The central magnet 22 is provided along the inner edge of the first groove 241. The pole pieces 21 are stacked on the central magnet 22 and form a gap between them and the outer magnets 23 to accommodate the voice coil 10. There is a gap between two adjacent outer magnets 23 to accommodate an FPC 31. The FPC 31 is connected to the driver 11.

[0020] That is, four outer magnets 23 are distributed around the central magnet 22, pole pieces 21 are stacked on the central magnet 22, and voice coil 10 is fitted into the pole pieces 21 and part of the central magnet 22 outside and located inside the four outer magnets 23. At the same time, the position of voice coil 10 corresponds to the position of the first groove 241.

[0021] Here, electrode 21 includes four handles 211, each of which is inserted into a single monomer 11.

[0022] That is, the pole piece 21, the central magnet 22, and the first groove 241 are all X-shaped.

[0023] Correspondingly, the diaphragm assembly 40 includes a dome 41 and a diaphragm 42 disposed around the dome 41. A first protrusion 411 is provided on the dome 41. The shape of the first protrusion 411 is consistent with the orthographic projection shape of the voice coil 10 and is connected to the voice coil 10 by means of adhesive bonding. That is, the first protrusion 411 is also X-shaped.

[0024] Furthermore, the frame 50 includes an outer frame 51 and a partition 52 disposed inside the outer frame 51. The partition 52 is disposed above the magnetic circuit 20. The partition 52 has a first opening 521 for accommodating the voice coil 10. The first opening 521 is generally X-shaped, and its four corners are extended outward to accommodate the FPC 31.

[0025] It should be noted that the voice coil 10 can also be other shapes. For example, when the N value is 4, the included angle between two adjacent units 11 is 90°, which forms a cross structure.

[0026] Alternatively, if N is 8, the included angle between any two adjacent monomers 11 is 45°, thus forming a roughly cross-shaped structure.

[0027] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
