Description

Technical Field

[0001] This utility model belongs to the field of headphone technology, specifically relating to a lightweight frame structure of a planar magnetic structure headphone and its headphones. Background Technology

[0002] In recent years, with the rapid development of audio technology, planar magnetic headphones have gradually become the mainstream product in the high-end audio market due to their excellent sound quality. Compared with traditional dynamic headphones, planar magnetic headphones use planar diaphragm technology, which involves printing precision circuits on the diaphragm and using a magnetic field to drive the diaphragm to vibrate and produce sound. This sound generation method can significantly reduce distortion while providing a wider frequency response and more delicate sound details, thus meeting users' needs for high-fidelity sound quality.

[0003] However, planar magnetic headphones still have some problems in practical applications, with weight being a particularly prominent issue. Specifically, planar magnetic headphones require multiple sets of magnets symmetrically arranged on both sides of the diaphragm to form a uniform magnetic field. The repulsive force between like poles of the magnets generates additional repulsive force on the magnet mounting frame. To ensure the stability of the magnet assembly and the uniformity of the magnetic field distribution, traditional designs typically use metal or high-strength materials to make the frame to resist the repulsive force. However, this increases the overall weight of the headphones, which can easily cause user fatigue during prolonged wear and affect the user experience. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems by providing a lightweight frame structure and earphones for a planar magnetic structure over-ear headphone, thereby improving the issues of excessive weight and poor user comfort during extended wear of existing over-ear headphones.

[0005] The technical solution adopted in this utility model is as follows: a lightweight frame structure for a planar magnetic structure over-ear headphone, the lightweight frame structure comprising:

[0006] The frame shell includes a front frame shell and a rear frame shell. The front frame shell is provided with a semi-circular arc-shaped magnet mounting and fixing strip. The rear frame shell is divided into an acoustic design and a component mating structure and a frame structure other than the acoustic design and component mating structure. The frame structure other than the acoustic design and component mating structure is arranged around the acoustic design and component mating structure. The frame structure other than the acoustic design and component mating structure is a recessed hollow structure.

[0007] The intermediate component is connected to the frame shell, with one side of the intermediate component connected to the front shell of the frame and the other side of the intermediate component connected to the rear shell of the frame.

[0008] Due to the aforementioned structural design, the rear shell of the frame, except for the necessary structures for acoustic design and component assembly, features a recessed, hollowed-out design. This design effectively reduces the weight of the rear shell without affecting acoustic performance or the structural function of component assembly. The area and shape of the hollowed-out area were precisely calculated, taking into account the overall weight distribution of the headphones, structural strength requirements, and usage scenarios. The acoustic design aims to optimize the external diffusion of sound waves, while the component assembly is achieved through screw holes on the front and rear shells, ensuring a stable fit. The hollowed-out structure, apart from the acoustic design and component assembly, does not negatively impact diffraction or the connection between the front and rear shells, while significantly reducing the overall weight of the rear shell, resulting in a lighter headphone structure.

[0009] The fixing strip on the front shell of the frame is semi-circular, which reduces the diffraction phenomenon when sound passes through, thereby improving the clarity and accuracy of the sound quality.

[0010] Furthermore, to reduce the use of connectors, the frame housing is made of a high-strength material. Magnets are directly bonded to corresponding magnet mounting slots within the frame housing, thus preventing connectors from interfering with sound quality.

[0011] High-strength materials such as metal alloys and polymer plastics.

[0012] Furthermore, in order to reduce the overall weight of the headphones while reducing sound wave diffraction and improving sound clarity and sound image positioning accuracy, the frame front shell includes a front shell and a semi-circular magnet mounting strip. The semi-circular magnet mounting strip is disposed on the front shell, and the protruding direction of the semi-circular magnet mounting strip is away from the front shell.

[0013] Furthermore, the intermediate component includes a diaphragm, a diaphragm frame, and a magnet assembly. The diaphragm is provided with a diaphragm coil. There are two diaphragm frames, one of which is a diaphragm frame with an integrated female base. The magnet assembly includes a front shell magnet assembly and a rear shell magnet assembly. The front shell magnet assembly is connected to the front shell of the frame, and the rear shell magnet assembly is connected to the rear shell of the frame.

[0014] The diaphragm is connected to two diaphragm plate frames on both sides.

[0015] Furthermore, the rear shell magnet assembly is installed in the magnet mounting slot of the frame rear shell, and the frame rear shell is used to fix the rear shell magnet assembly.

[0016] Furthermore, the front shell magnet assembly is connected to the semi-circular arc magnet mounting strip, which is used to fix the front shell magnet assembly. The front shell magnet assembly is connected to the front shell of the frame through the semi-circular arc magnet mounting strip.

[0017] Furthermore, in order to maximize the utilization of magnetic field energy, the diaphragm coil adopts a serpentine winding structure.

[0018] Furthermore, to reduce the interference of exposed bends in the magnetic field uniformity, the diaphragm frame is designed with two layers, upper and lower, which clamp and encapsulate the bends of the diaphragm coil. The diaphragm coil uses a serpentine winding structure, and its bends are completely encapsulated within the sandwich of the double-layer diaphragm frame, thereby eliminating the interference of exposed bends in the magnetic field uniformity in traditional designs.

[0019] Furthermore, the two diaphragm frames are connected to the middle diaphragm by adhesive.

[0020] Furthermore, the diaphragm is held and fixed by two diaphragm plate frames, one of which is provided with an integrated female base, and both diaphragm plate frames are designed with a circular hollow structure.

[0021] Furthermore, a planar magnetic structure headset is provided, wherein the planar magnetic structure headset uses a lightweight frame structure.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0023] 1. This utility model reduces the weight of headphones by combining external contour hollowing with internal structural optimization.

[0024] 2. This utility model reduces the weight of the rear frame by designing it as a recessed, hollowed-out structure, excluding the acoustic design and necessary component fitting structures. Furthermore, the hollowed-out design of the frame structure does not affect the structural function of the acoustic design and necessary component fitting structures. The fixing strip on the front frame is designed as a semi-circular arc, reducing diffraction of sound as it passes through, thereby improving the clarity and accuracy of the sound quality. Thus, it is possible to improve the clarity and accuracy of the headphone sound quality while reducing the headphone's weight.

[0025] 3. This utility model designs the diaphragm frame as two layers, which are used to clamp and encapsulate the bending points of the diaphragm coil. Furthermore, the diaphragm coil uses a serpentine winding structure, with its bending and routing areas completely encapsulated within the sandwich structure of the double-layer diaphragm frame. This eliminates the interference of exposed bends in the wiring on the uniformity of the magnetic field, as is common in traditional designs, further improving the sound quality and safety of the headphones.

Detailed Implementation

[0038] The present invention will now be described in detail with reference to the accompanying drawings.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0040] This invention optimizes the structural design of the magnet mounting frame while ensuring magnetic field driving performance, thereby achieving lightweight headphones and improving wearing comfort.

[0041] like Figures 1-10 As shown, a lightweight frame structure for a planar magnetic structure headset is disclosed, the lightweight frame structure comprising:

[0042] The frame housing 1 includes a front frame housing 2 and a rear frame housing 3. The front frame housing 2 is provided with a semi-circular arc-shaped magnet mounting and fixing strip 202. The rear frame housing 3 is divided into an acoustic design and part fitting necessary structure 301 and a frame structure 302 other than the acoustic design and part fitting necessary structure. The frame structure 302 other than the acoustic design and part fitting necessary structure is arranged around the acoustic design and part fitting necessary structure 301. The frame structure 302 other than the acoustic design and part fitting necessary structure is a recessed hollow structure.

[0043] The intermediate component 5 is connected to the frame shell 1, and one side of the intermediate component 5 is connected to the front shell 2 of the frame, while the other side of the intermediate component 5 is connected to the rear shell 3 of the frame.

[0044] A planar magnetic structure headset has the following structure: an intermediate component 5 is disposed between the front shell 2 and the rear shell 3 of the frame, forming a protective outer shell. The frame shell 1 is connected to an ergonomic headband 9, which is adapted to fit the human head.

[0045] Example 1

[0046] In one embodiment of this utility model, the frame housing 1 is made of a high-strength material, and a magnet assembly 8 is provided in the intermediate component 5. The magnet assembly 8 is connected to the frame housing 1 by adhesive bonding. The planar magnetic earphone utilizes Ampere force to drive the diaphragm 6 to vibrate. Unlike traditional dynamic earphones, the planar magnetic earphone lays the current-carrying circuitry flat on the diaphragm 6 using methods such as printed circuitry and etched circuitry. Then, the magnets are arranged in opposite pairs with opposite polarities, so that the magnetic field lines are parallel to the diaphragm 6 and perpendicular to the current direction in the circuit. This allows the signal to generate an Ampere force perpendicular to the diaphragm 6 through the circuitry on the diaphragm 6, driving the diaphragm 6 to vibrate.

[0047] By utilizing the positive and negative poles of magnets, the arrangement of the magnet group 8 and the frame housing 1 ensures that the normal operation of the headphones is not affected while maintaining structural stability.

[0048] Example 2

[0049] like Figures 3-4 As shown, in one embodiment of the present invention, the front shell 2 of the frame includes a front shell 201 and a semi-circular magnet mounting and fixing strip 202. The semi-circular magnet mounting and fixing strip 202 is disposed on the front shell 201, and the protruding direction of the semi-circular magnet mounting and fixing strip 202 is the side away from the front shell 201.

[0050] The semi-circular magnet mounting strip 202 not only reduces weight, but also effectively reduces the diffraction phenomenon generated when sound passes through the magnet, thereby improving the clarity and accuracy of sound quality.

[0051] Example 3

[0052] like Figure 6 As shown, in another embodiment of the present invention, the intermediate component 5 includes a diaphragm 6, a diaphragm frame 7, and a magnet assembly 8. The diaphragm 6 is provided with a diaphragm coil 601. There are two diaphragm frames 7, one of which is a diaphragm frame 7 with an integrated female base. The magnet assembly 8 includes a front shell magnet assembly 801 and a rear shell magnet assembly 802. The front shell magnet assembly 801 is connected to the front shell 2 of the frame, and the rear shell magnet assembly 802 is connected to the rear shell 3 of the frame.

[0053] The diaphragm 6 is connected to two diaphragm plate frames 7 on both sides.

[0054] The integrated female base design of the diaphragm frame 7 simplifies the assembly process and improves the overall structural stability. The front shell magnet assembly 801 and the rear shell magnet assembly 802 are made of permanent magnet material, and the magnetic circuit distribution has been calculated to ensure that the magnetic field is uniform while completely covering the effective vibration area of ​​the diaphragm 6, effectively improving driving efficiency and acoustic performance.

[0055] Example 4

[0056] like Figure 9 As shown, in another embodiment of the present invention, the rear shell magnet assembly 802 is connected to the acoustic design and parts matching necessary structure 301 of the frame rear shell 3, and the rear shell magnet assembly 802 is installed in the magnet mounting groove of the frame rear shell.

[0057] The acoustic design and component fitting necessary structure 301 is connected to the rear shell magnet assembly 802 to form a magnetic circuit. The frame structure 302 of the rear shell 3, excluding the acoustic design and component fitting necessary structure, is recessed and hollowed out. This frame structure 302, excluding the acoustic design and component fitting necessary structure, does not contact the rear shell magnet assembly 802. Therefore, the frame structure 302, excluding the acoustic design and component fitting necessary structure, can be set as a recessed and hollowed-out structure. This can reduce the overall weight of the headphones to a certain extent.

[0058] Example 5

[0059] like Figure 9 As shown, in another embodiment of this utility model, the front shell magnet assembly 801 is connected to a semi-circular magnet mounting strip 202. The semi-circular magnet mounting strip 202 is used to fix the front shell magnet assembly 801, and the front shell magnet assembly 801 is connected to the front shell 2 of the frame through the semi-circular magnet mounting strip 202. The rear shell magnet assembly 802 is also provided with a strip magnet mounting strip 303.

[0060] When the frame housing 1 is a single unit, the front housing magnet assembly 801 and the rear housing magnet assembly 802 are close to each other, and there is a gap between them; the two close-to-each front and rear housing magnets are opposite magnetic poles. The protrusion of the semi-circular magnet mounting strip 202 is closer to the ear, and the strip magnet mounting strip 303 is located on the side away from the ear.

[0061] The semi-circular magnet mounting strip 202 near the ear is designed to reduce sound wave diffraction, thereby improving the clarity and accuracy of the sound quality.

[0062] Example 6

[0063] like Figure 8 The diagram illustrates sound wave diffraction. The left side shows a single magnet, while the right side shows a magnet with a semi-circular fixing strip. According to... Figure 9 It can be concluded that adding a semi-circular arc-shaped fixing strip to the magnet significantly reduces sound wave diffraction. Furthermore, most fixing strips currently use a long, narrow design; this embodiment, by setting the magnet fixing strip near the ear to a semi-circular arc shape, effectively reduces sound wave diffraction and improves headphone sound quality.

[0064] Example 7

[0065] like Figure 5 and Figure 10 As shown, in another embodiment of this utility model, the diaphragm coil 601 adopts a serpentine winding structure. The bends in the diaphragm coil 601 are completely encapsulated inside the diaphragm frame 7, thereby eliminating the interference of exposed bends in the magnetic field uniformity caused by traditional designs. At the same time, the design of the front shell magnet assembly 801 and the rear shell magnet assembly 802 respectively located on both sides of the diaphragm 6 allows the magnets to completely cover the effective vibration area of ​​the diaphragm 6, thereby significantly improving driving efficiency and acoustic performance.

[0066] Example 8

[0067] like Figure 5As shown, in another embodiment of this utility model, the diaphragm frame 7 is designed with two layers, upper and lower, which are used to clamp and encapsulate the bending points of the diaphragm coil 601. The diaphragm coil 601 adopts a serpentine winding structure, and its bending wiring area is completely encapsulated inside the sandwich of the double-layer diaphragm frame 7, thereby eliminating the interference of exposed bending lines on the uniformity of the magnetic field in traditional designs.

[0068] Furthermore, a diaphragm plate frame 7 is integrated with a female base, which simplifies the assembly process of the overall structure and improves the stability of the overall structure.

[0069] Example 9

[0070] like Figure 7 As shown, another embodiment of this utility model is a planar magnetic structure headphone, including a headband 9 and a lightweight frame connected to the headband 9.

[0071] The headband 9 is designed based on ergonomic principles, conforming to an ergonomic structure, optimizing weight distribution and wearing comfort, and boasting strong overall structural stability. It ensures comfort while also considering structural strength and long-term durability. Furthermore, this embodiment employs an innovative adjustable leather band position, effectively solving problems such as unstable straps, head clamping, and neck pain inherent in traditional over-ear headphones. The lightweight perforated design on the headband 9 not only reduces overall weight but also optimizes the distribution of clamping force, allowing the product to maintain comfort even during extended wear. The modular sliding block structure facilitates maintenance and replacement, further extending the product's lifespan.

[0072] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
