Description

Technical Field

[0001] The present invention specifically relates to the technical field of loudspeakers, in particular to a conductive wire bundle sound-generating structure and a loudspeaker thereof. Background Art

[0002] Speakers can generally be divided into the following four categories according to the shape of the diaphragm: cone speakers, dome speakers, flat speakers, ribbon speakers, etc.

[0003] All speakers work based on the principle of electromagnetic induction. Among them, the cone, dome and flat speakers all have independent voice coils, which are composed of a frame and a coil wound on it. When the audio current passes through the coil of the speaker, the coil will generate a magnetic field. This magnetic field interacts with the magnetic field of the permanent magnet of the speaker, driving the voice coil to move in the magnetic field. The voice coil is connected to the diaphragm of the speaker. The forced vibration of the diaphragm will drive the vibration of the air, thereby generating sound waves, realizing the process of converting electrical signals into sound signals.

[0004] The fourth type of ribbon speakers generally include two types. One is to print the wire or coil directly on the thin ribbon diaphragm, directly driving the ribbon diaphragm to vibrate. Common types include isomagnetic field ribbon speakers and Haier (jet) speakers. The other is to directly drive the metal film in the magnetic field to vibrate and produce sound. The most common type is the aluminum ribbon speaker.

[0005] Among the above four types of speakers with diaphragm shapes, the cone, dome and flat-panel speakers all use voice coils to indirectly drive the diaphragm to produce sound, so the high-frequency response is still not good enough, while the fourth type of ribbon speaker uses the diaphragm to vibrate directly to produce sound, so the high-frequency response is better than the former. However, the efficiency of the ribbon diaphragm coupling energy with the air at high-frequency vibration is still not ideal. Summary of the invention

[0006] The purpose of the present invention is to provide a conductive wire bundle sound-producing structure and a speaker thereof, which are formed by arranging a plurality of ultra-fine conductive wire bundles. When current passes through a diaphragm formed by the wire bundles, the wire bundles react more sensitively, and thus can quickly drive the air, thereby improving the high-frequency characteristics of the speaker; so as to solve the technical problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A conductive wire bundle sounding structure comprises a conductive wire and an electrode plate. The conductive wire is connected with two electrode plates and arranged to form one or more surfaces.

[0009] As a further technical solution of the present invention, there are multiple conductive threads, and both ends of each conductive thread are respectively connected to two electrode plates.

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

[0011] As a further technical solution of the present invention, the conductive filament bundle is composed of one or more fibers of different sizes and lengths.

[0012] As a further technical solution of the present invention, there are multiple conductive threads, and the multiple conductive threads are arranged to form multiple surfaces, and the multiple surfaces overlap to form a diaphragm structure that is beneficial to the diffusion of sound waves.

[0013] As a further technical solution of the present invention, there are multiple conductive threads arranged flatly to form a plurality of planes or curved surfaces.

[0014] As a further technical solution of the present invention, two L-shaped electrode plates are provided; a plurality of 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 the present invention, two ends of the plurality of conductive wires are welded to the electrode plates.

[0016] As a further technical solution of the present invention, the electrode plates are provided with two C-shaped plates; the two electrode plates are connected by an insulating connecting sheet;

[0017] The bottoms of both ends of the two electrode plates are provided with card slots, and a positioning groove is provided in each card slot; positioning posts are provided at both ends of the insulating connecting piece, and the insulating connecting piece is fixedly connected with the card slot and the positioning groove through the positioning posts.

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

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The structural characteristics of the sound produced by the tow in the present invention make it respond to audio signals more quickly and transmit sound signals more delicately compared to the one-piece diaphragm because it improves the coupling ability of weak high-frequency electrical signals into sound waves. The size of the tow and the density and shape of the arrangement can be adjusted to distribute energy more evenly when vibrating, reduce sound distortion caused by excessive or uneven local vibration, and perform well at lower input power. This enables the speaker to better analyze the details in the audio signal, such as the subtle changes in notes in the music, the breathing of the singer and other details can be more clearly displayed.

[0021] 2. The uniformity and stability of the fiber bundle sound-generating structure of the present invention 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 strength of the input audio signal, thereby reducing harmonic distortion and intermodulation distortion.

[0022] 3. In the present invention, the diaphragm needs to vibrate quickly to generate high-frequency sound waves. The structure of the sound-generating wire bundle uses ultra-fine conductive wire bundles arranged in a magnetic field to directly drive the air to make sounds, which is similar to the way our palms paddle when we swim. It is more efficient to paddle with a slight gap between the fingers than to form a relatively narrow continuous surface together, which greatly improves the energy conversion coupling efficiency from audio electrical signals to air vibrations, has better high-frequency response, and more transparent sound; the sound-generating wire bundle structure can quickly vibrate in accordance with the changes in high-frequency electrical signals, so that high-frequency sounds can be restored more accurately, making the frequency response of the speaker in the high-frequency band more transparent and bright.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-4 In an 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 or carbon fiber, and a composite conductive material.

[0033] The structural characteristics of the wire bundle diaphragm are conducive to rapid response to high-frequency signals, so it is more transparent and delicate in high frequencies than paper diaphragms. The wire bundle material can distribute energy more evenly when vibrating, reducing sound distortion caused by excessive or uneven local vibration. This allows the speaker to better analyze the details in the audio signal, such as the tiny note changes in the music, the singer's breathing and other details can be more clearly displayed.

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

[0035] Embodiment 1

[0036] Please see attached Figure 1 In this embodiment, the conductive wire bundle sounding structure is formed by a conductive wire 1 being reciprocatingly wound in an "S" shape. Two electrode plates 3 are provided in an L shape; a plurality of hooks 2 are fixed inside the electrode plates 3; the conductive wire is wound around the hooks 2 to form a conductive wire bundle sounding structure.

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

[0038] Embodiment 2

[0039] Please see attached Figure 2 In this embodiment, the conductive wire bundle sound generating structure is formed by a plurality of conductive wires 1 arranged in a straight line and closely attached to each other, and both ends of each conductive wire 1 are respectively connected to two electrode plates 3. The plurality of conductive wires 1 are arranged and laid flat to form a plurality of surfaces, and there is a certain gap between each surface, and the plurality of surfaces overlap to form a diaphragm structure that is conducive to the diffusion of sound waves. The surface formed by the plurality of conductive wires 1 is a plane or a curved surface.

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

[0041] Embodiment 3

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

[0043] The conductive wire 1 and the electrode plate 3 are fixed by welding, which is firm and convenient for the transmission of the magnetic field.

[0044] Embodiment 4

[0045] Please see attached Figure 4 In this embodiment, the electrode plates 3 are C-shaped and are provided with two; the two electrode plates 3 are connected by an insulating connecting piece 32.

[0046] By adopting the above technical solution, it is very suitable for the use of circular speakers, has a simple structure and is easy to install.

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

[0048] This ensures the compactness of the conductive threads, and ensures the listening effect of the music when they vibrate under the action of the magnetic field.

[0049] As a further description of the fourth embodiment, the bottoms of both ends of the two electrode plates 3 are provided with slots 31 , and each slot 31 has a positioning slot 33 ; and positioning posts 34 are provided at both ends of the insulating connecting piece 32 .

[0050] The insulating connecting piece 32 is fixedly connected with the clamping slot 31 and the positioning slot 33 by means of the positioning column 34 , and has a simple structure and is convenient for assembly and disassembly.

[0051] A loudspeaker with a wire bundle diaphragm, wherein the conductive wire bundle sound-generating 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 silk bundles are generally thin and light. For example, some diaphragm tweeter diaphragms made of silk material can be much lighter than traditional paper diaphragms. This thin and light feature allows the diaphragm to respond quickly to high-frequency signals. In the high-frequency part of the audio signal, the conductive silk bundle sound-generating structure needs to vibrate quickly to generate high-frequency sound waves. The conductive silk bundle sound-generating structure can vibrate quickly to follow the changes in the high-frequency electrical signal, so that the high-frequency sound can be restored more accurately, making the speaker's frequency response in the high-frequency band wider and smoother.

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

[0054] The working principle of the present invention is ( Figure 7 ): After the impedance transformer module 6 adjusts the impedance matching between the audio signal and the conductive wire bundle, it is transmitted to the two ends of the electrode plate 1 and the electrode plate 3 through the wire. The alternating audio signal voltage is added to the two ends of each conductive wire bundle, and the alternating audio signal current will flow through each conductive wire bundle. Since the conductive wire bundle is in the magnetic field level generated by the first magnet 4 and the second magnet 5, according to the left-hand rule, the audio signal current will cause each conductive wire bundle to vibrate vertically back and forth by the Ampere force. Because the air has a certain viscosity, the conductive wire bundle grid close to each other is almost equivalent to a dense diaphragm for it. When many conductive wire bundles vibrate, the air is also driven to make sounds. The structural characteristics of the conductive wire bundle sounding enable it to transmit sound signals more delicately during the vibration process. The arrangement of the wire bundle material can distribute energy more evenly during vibration, reducing the sound distortion caused by excessive or uneven local vibration. This enables the speaker to better analyze the details in the audio signal, such as the changes in the tiny notes in the music, the breathing of the singer and other details can be more clearly displayed.

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