Description

Technical Field

[0001] This utility model specifically relates to the field of loudspeaker technology, and more specifically to a conductive wire bundle sound-producing structure and its loudspeaker. Background Technology

[0002] Loudspeakers can generally be classified into the following categories according to the shape of their diaphragms: cone loudspeakers, dome loudspeakers, flat panel loudspeakers, and ribbon loudspeakers.

[0003] All loudspeakers operate based on the principle of electromagnetic induction. Cone, dome, and planar loudspeakers each have an independent voice coil, which consists of a frame and a coil wound around it. When an audio current passes through the speaker's coil, the coil generates a magnetic field. This magnetic field interacts with the magnetic field of the speaker's built-in permanent magnet, causing the voice coil to move within the magnetic field. The voice coil is connected to the speaker's diaphragm, and the forced vibration of the diaphragm drives the vibration of the air, thus generating sound waves, achieving the process of converting electrical signals into sound signals.

[0004] The fourth type of ribbon loudspeaker generally includes two types. One type has wires or coils printed directly on a thin ribbon diaphragm, which directly drives the ribbon diaphragm to vibrate and produce sound. Common types include isodynamic ribbon loudspeakers and Hell (jet) loudspeakers. The other type directly drives a metal film in a magnetic field to vibrate and produce sound. Common types include aluminum ribbon loudspeakers.

[0005] Of the four types of diaphragm loudspeakers mentioned above, the cone, dome, and planar loudspeakers all rely on the voice coil to indirectly drive the diaphragm, resulting in insufficient high-frequency response. The ribbon loudspeaker, on the other hand, produces sound through direct diaphragm vibration, thus offering a superior high-frequency response. However, the energy coupling efficiency between the ribbon diaphragm and air during high-frequency vibration remains less than ideal. Utility Model Content

[0006] The purpose of this invention is to provide a conductive wire bundle sound-producing structure and its loudspeaker, which is composed of many ultra-fine conductive wire bundles arranged together. When current passes through the diaphragm formed by the wire bundles, the wire bundles react more sensitively, thus quickly moving the air and improving the high-frequency characteristics of the loudspeaker; thereby solving the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A conductive wire bundle sound-emitting structure includes conductive wires and electrode plates, wherein the conductive wires are connected and arranged with the two electrode plates to form one or more surfaces.

[0009] As a further technical solution of this utility model, the conductive wire is multiple, and the two ends of each conductive wire are respectively connected to two electrode plates.

[0010] As a further technical solution of this utility model, the conductive wire material is metal or carbon fiber and composite conductive material.

[0011] As a further technical solution of this utility model, the conductive wire bundle is composed of one or more fibers of different sizes and lengths.

[0012] As a further technical solution of this utility model, the conductive wire is provided with multiple wires, which are arranged to form multiple surfaces, and the multiple surfaces overlap to form a diaphragm structure that is conducive to the diffusion of sound waves.

[0013] As a further technical solution of this utility model, the conductive wire is provided in multiple strands, which are laid out in a flat manner to form several planes or curved surfaces.

[0014] As a further technical solution of this utility model, two electrode plates are arranged in an L-shape; several hooks are fixed on the inner side of the electrode plates; and conductive wires are wound around the hooks to form a wire bundle diaphragm.

[0015] As a further technical solution of this utility model, the two ends of multiple conductive wires are welded to the electrode plate.

[0016] As a further technical solution of this utility model, the electrode plates are arranged in a C-shape in two parts; the two electrode plates are connected by an insulating connecting piece.

[0017] Both ends of the two electrode plates have slots at their bottom, and each slot has a positioning groove. The insulating connecting piece has positioning posts at both ends, and the insulating connecting piece is fixed to the slots and positioning grooves by the positioning posts.

[0018] As a further technical solution of this utility model, the conductive wire is located between the first magnet and the second magnet; the electrode plate is electrically connected to the impedance transformer module.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model utilizes the structural characteristics of a filament-driven sound system. Compared to a one-piece molded diaphragm, it enhances the coupling ability of weak high-frequency electrical signals into sound waves, enabling a faster response to audio signals and a more delicate transmission of sound signals. By adjusting the size, density, and shape of the filament bundles, energy can be distributed more evenly during vibration, reducing sound distortion caused by excessive or uneven local vibrations, and achieving good performance even at lower input power. This allows the speaker to better resolve details in the audio signal, such as subtle changes in musical notes and the singer's breathing sounds, revealing them more clearly.

[0021] 2. In this invention, the uniformity and stability of the filament-driven sound-producing structure help reduce sound distortion. Due to its structure and material properties, it can vibrate in a more linear manner. This linear vibration means that the displacement of the diaphragm is proportional to the intensity of the input audio signal, thereby reducing harmonic distortion and intermodulation distortion.

[0022] 3. In this invention, the diaphragm needs to vibrate rapidly to generate high-frequency sound waves. The filament-driven sound structure utilizes ultra-fine conductive filaments arranged in a magnetic field to directly drive the air to produce sound, similar to the hand paddling in swimming. Leaving a slight gap between the fingers is more efficient than forming a relatively narrow continuous surface when paddling, greatly improving the energy conversion coupling efficiency from audio electrical signals to air vibrations, resulting in better high-frequency response and clearer sound. The filament-driven sound structure can quickly follow changes in high-frequency electrical signals to vibrate, thus more accurately reproducing high-frequency sounds and making the speaker's frequency response in the high-frequency range more transparent and bright.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-4 In this embodiment of the present invention, a wire bundle diaphragm is provided. The wire bundle diaphragm 1 is made of one or more conductive wires arranged on an electrode plate 3. The conductive wire (1) is made of metal, carbon fiber, or composite conductive material.

[0033] The structural characteristics of a wire-tethered diaphragm facilitate a rapid response to high-frequency signals, resulting in a more transparent and refined high-frequency response compared to a paper diaphragm. The wire-tethered material distributes energy more evenly during vibration, reducing sound distortion caused by excessive or uneven localized vibrations. This allows the speaker to better resolve details in the audio signal, such as subtle changes in musical notes and the singer's breathing sounds, revealing them more clearly.

[0034] The uniformity and stability of the filament diaphragm help reduce sound distortion. Due to its structure and material properties, it can vibrate in a more linear manner when driven by a voice coil. This linear vibration means that the diaphragm displacement is proportional to the intensity of the input audio signal, thereby reducing harmonic distortion and intermodulation distortion.

[0035] Example 1

[0036] Please see the appendix Figure 1 In this embodiment, the conductive wire bundle sound-producing structure is formed by a conductive wire 1 arranged in an "S" shape and wound back and forth. There are two electrode plates 3 arranged in an L shape; several hooks 2 are fixed inside the electrode plates 3; the conductive wire is wound around the hooks 2 to form the conductive wire bundle sound-producing structure.

[0037] The conductive wire 1 is made by winding. By stretching one end of the conductive wire, the conductive wire can be tightened, which is very convenient when winding.

[0038] Example 2

[0039] Please see the appendix Figure 2 In this embodiment, the conductive wire bundle sound-producing structure is composed of multiple conductive wires 1 arranged in a straight line and tightly bonded together. Both ends of each conductive wire 1 are connected to two electrode plates 3. The multiple conductive wires 1 are arranged flat to form multiple surfaces, with a certain gap between each surface. The overlapping of these surfaces forms a diaphragm structure that facilitates sound wave diffusion. The surfaces formed by the multiple conductive wires 1 can be planar or curved.

[0040] By adopting the above technical solution, when one of the conductive wires breaks, it will not affect the sound production and use of the entire speaker, and repair is more convenient.

[0041] Example 3

[0042] Please see the appendix Figure 3 In this embodiment, the two ends of multiple conductive wires 1 are welded to the electrode plate 3.

[0043] Welding is used to fix the conductive wire 1 to the electrode plate 3, which is secure and facilitates the transmission of magnetic field.

[0044] Example 4

[0045] Please see the appendix Figure 4 In this embodiment, two electrode plates 3 are arranged in a C-shape; the two electrode plates 3 are connected by an insulating connecting piece 32.

[0046] The above technical solution is very suitable for use with round speakers, as it has a simple structure and is easy to install.

[0047] As a further illustration of the above embodiments, the conductive wire may be, but is not limited to, a combination of one or more fibers of different sizes and lengths.

[0048] This ensures the tightness between the conductive wires, guaranteeing a good listening experience when the magnetic field causes vibrations.

[0049] As a further explanation of Embodiment 4, slots 31 are provided at the bottom of both ends of the two electrode plates 3, and a positioning groove 33 is provided in each slot 31; positioning posts 34 are provided at both ends of the insulating connecting piece 32.

[0050] The insulating connecting piece 32 is fixed by the positioning post 34 to the slot 31 and the positioning groove 33, which is simple in structure and easy to disassemble and assemble.

[0051] A loudspeaker with a filament diaphragm, wherein the conductive filament sound-producing structure is located between a first magnet 4 and a second magnet 5; the electrode plate 3 is electrically connected to an impedance transformer module 6. It can be understood that the first magnet 4 and the second magnet 5 can be permanent magnets or electromagnets.

[0052] Conductive filament bundles are generally quite thin and light. For example, some diaphragm tweeters using filamentous materials can be much lighter than traditional paper diaphragms. This thinness and lightness allows the diaphragm to respond quickly to high-frequency signals. In the high-frequency range of audio signals, the conductive filament bundle sound-producing structure needs to vibrate rapidly to generate high-frequency sound waves. The conductive filament bundle sound-producing structure can quickly follow changes in high-frequency electrical signals, thus more accurately reproducing high-frequency sounds and making the speaker's frequency response wider and smoother in the high-frequency range.

[0053] Traditional speaker diaphragms may have certain limitations in high-frequency response. For example, paper diaphragms, due to their own mass and material properties, may not be able to keep up with signal changes at high frequencies, resulting in insufficient high-frequency extension and loss of sound details. For instance, when playing high-pitched string sections in classical music or high-frequency effects in some electronic music, traditional paper diaphragms may not be able to reproduce the crisp and bright high-frequency timbre very well.

[0054] The working principle of this utility model is ( Figure 7 The impedance transformer module 6 adjusts the impedance of the audio signal and the conductive wire bundles, then transmits it to the two ends of electrode plates 1 and 3 via wires. An alternating audio signal voltage is applied across each conductive wire bundle, and an alternating audio signal current flows through each bundle. Since the conductive wire bundles are in the same magnetic field generated by the first magnet 4 and the second magnet 5, according to the left-hand rule, the audio signal current causes each wire bundle to vibrate back and forth perpendicular to the plane of the paper due to the Ampere force. Because air has a certain viscosity, the closely spaced conductive wire mesh is almost equivalent to a dense diaphragm. When numerous conductive wire bundles vibrate, the air is also moved to produce sound. The structural characteristics of the conductive wire bundles allow them to transmit sound signals more delicately during vibration. The arrangement of the wire bundle material allows for a more even distribution of energy during vibration, reducing sound distortion caused by excessive or uneven local vibration. This enables the speaker to better resolve details in the audio signal, such as subtle changes in musical notes and the singer's breathing sounds, which are all more clearly revealed.

[0055] The uniformity and stability of the conductive filament acoustic structure help reduce sound distortion. Due to its structure and material properties, it can vibrate in a more linear manner during operation. This linear vibration means that the diaphragm displacement is proportional to the intensity of the input audio signal, thereby reducing harmonic distortion and intermodulation distortion.
