Technical Field
[0001] This utility model relates to the field of loudspeaker technology, and more specifically, to a novel low-distortion loudspeaker. Background Technology
[0002] A loudspeaker is a modern electroacoustic component, also known as a loudspeaker, primarily used to convert electrical signals into sound. This type of loudspeaker is widely used in various electronic devices and audio systems, including car horns and audio equipment. Its sound-producing principle is based on the process of converting electrical energy into sound. When electronic energy is transferred to a coil, the coil interacts with the magnetic field of a magnet, causing a diaphragm to vibrate, thus producing sound. This device is very common in electronic and electrical equipment and is an important component for ensuring the transmission of communication, entertainment, and warning signals.
[0003] However, existing loudspeakers have the following problems when in use:
[0004] As consumers' demands for audio experience continue to rise, their expectations for speaker performance are becoming increasingly stringent, particularly in the pursuit of a synergistic effect of high power output and low distortion. However, in actual use, existing speaker products often require driving the diaphragm to generate a larger amplitude to meet the high power demand. In this process, severe distortion is easily triggered, leading to a sharp deterioration in sound quality and failing to achieve the high-fidelity listening experience expected by consumers.
[0005] This invention can firmly fix each component through the bracket, connecting plate, washer, and connecting groove, resist external impact, prevent displacement and shaking, and extend life. At the same time, the stable magnetic field constructed by the washer and magnet ensures that the voice coil is subjected to force and vibrates accurately, ensuring accurate conversion from electrical signal to sound, reducing signal deviation, increasing speaker power, suppressing oscillation, and reducing low-frequency distortion. Utility Model Content
[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a new type of low-distortion speaker.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel low-distortion speaker, comprising: a bracket, wherein a washer is disposed inside the bracket, and magnets are disposed between the washers, wherein the washer is composed of an upper washer and a lower washer, a magnet is held between the upper washer and the lower washer, and a voice coil is held between the magnets.
[0008] A further preferred embodiment: a connecting plate is fixedly connected to the upper end of the bracket, a diaphragm is fixedly installed in the middle of the connecting plate, and the washer is located below the diaphragm.
[0009] Further preferred: the inner bottom of the bracket and the connecting plate together clamp the amorphous metal, and the front and rear ends of the inner part of the bracket clamp the magnet together with the amorphous metal.
[0010] Further preferred: the upper and lower amorphous metals are provided with connecting grooves on the front and rear sides of the upper end, and the connecting grooves of the upper and lower amorphous metals are provided with magnets.
[0011] Further preferred: the magnet is divided into three, and the three magnets form two clamping surfaces, and the voice coil is clamped by the clamping surface.
[0012] Further preferred: the upper and lower ends of the voice coil are accommodated in the connecting grooves.
[0013] Beneficial effects:
[0014] 1. By providing amorphous metals and connecting grooves, the amorphous metals are usually made of magnetic conductive materials. On the one hand, it can effectively guide the magnetic field generated by the magnet, concentrate the relatively dispersed magnetic lines according to the design requirements, and accurately converge to the area where the voice coil is located, so that the voice coil can accurately and efficiently respond to the electrical signal in the electromagnetic conversion process, greatly reducing the sound fluctuation and distortion caused by uneven magnetic field. On the other hand, the split structure of the amorphous metal composed of upper and lower amorphous metals tightly clamps the magnet from the top and bottom directions, so that the magnet will not easily shake or deviate due to external vibration or mechanical fatigue caused by long-term use during work. The stability of the magnetic field is continuously ensured. For the voice coil, its upper and lower ends are accommodated in the connecting grooves, so that it will not wander during vibration, and will always move accurately along the predetermined track, ensuring that the relative position relationship between the voice coil and the magnetic field remains constant, thereby allowing the diaphragm to receive stable and regular driving force, making the diaphragm vibrate more smoothly and linearly, and ultimately allowing each note emitted from the loudspeaker to be clear and pure, improving the loudspeaker power, suppressing the swing, and reducing the low-frequency distortion.
[0015] 2. By providing magnets, the magnet is divided into three, and the two clamping surfaces formed between them accurately clamp the voice coil. This unique design further enhances the control ability of the voice coil. The clamping surface is like a precise "positioning clamp", which allows the voice coil to always be in the strongest effective area of the magnetic field, avoiding even slight deviation or shaking of the voice coil during vibration, ensuring that the voice coil is evenly stressed and moves accurately and accurately, driving the diaphragm to accurately reproduce every detail of the sound, achieving full-range, multi-level low-distortion sound effect.
[0016] 3. In summary, this novel low-distortion speaker incorporates a diaphragm, washer, connecting slots, magnet, and voice coil. The washer consists of two parts, upper and lower, with a magnetically conductive material precisely guiding and concentrating the magnetic field of the magnet, creating a stable and uniform dynamic environment for the voice coil. Its split design, combined with the clamping and fixing of the bracket and connecting plate, ensures the stability of itself and the overall structure. The connecting slots are located on both sides of the upper end of the washer, serving as a "navigation" for the installation of the magnet and voice coil. This improves assembly efficiency and precision, and also limits the horizontal displacement of the two during operation, ensuring the stability of the magnetic field and voice coil movement. The magnet, as the core of the magnetic field, is clamped by the washer, and the multi-piece layout forms a precise clamping surface to control the voice coil, providing stable power and driving it to vibrate according to the electrical signal. The voice coil accurately receives the electrical signal and converts it into mechanical vibration, which is then transferred to the diaphragm through the stable connecting structure. The diaphragm, with its elasticity and flexibility, replicates the vibration characteristics of the voice coil. The vibration causes changes in air density, thereby increasing the speaker's power, suppressing sway, and reducing low-frequency distortion. Attached Figure Description

[0022] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.
[0023] Please see Figures 1-4The utility model discloses an embodiment of a kind of novel low distortion loudspeaker, comprising: support 1, support 1 inside is provided with hua si 2, hua si 2 between being provided with magnet 3, hua si 2 is composed of upper hua si 201 and lower hua si 202, magnet 3 is clamped between upper hua si 201 and lower hua si 202, support 1 upper end is fixedly connected with connecting plate 101, connecting plate 101 middle part is fixedly installed with diaphragm 102, hua si 2 is below diaphragm 102, support 1 inside bottom and connecting plate 101 jointly clamp hua si 2, support 1 inside front and rear ends are matched with hua si 2 and magnet 3 is clamped, support 1 is as the basic frame of entire loudspeaker structure, provide the space of installation and positioning for other components in inside, guarantee the stability and compactness of entire loudspeaker structure.Support 1 upper end is fixedly connected with connecting plate 101, so that diaphragm 102 can be stably at corresponding position, construct reasonable framework for the generation and propagation of sound. Meanwhile, the bottom of the inside of the bracket 1 and the connecting plate 101 jointly clamp the hua si 2, fix the hua si 2 from the top and bottom two directions, prevent it from shifting and other conditions during the operation of the loudspeaker, ensure the accuracy of the position of the hua si 2, and, the front and rear ends of the inside of the bracket 1 are matched with the hua si 2 and the magnet 3 is clamped, this multidirectional fixing mode makes the magnet 3 can be stably placed in the set magnetic field position, provides a stable magnetic field environment for the voice coil 301, the hua si 2 is composed of the upper hua si 201 and the lower hua si 202, such split type structure facilitates the clamping operation of the magnet 3 in the assembly process, and can limit and fix the magnet 3 from the top and bottom two directions, so that the magnet is not easy to shake or deviate during operation, which helps to maintain the uniformity and stability of the magnetic field. The role in the construction of the magnetic field: hua si 2 is usually made of magnetic conductive material, which can guide and concentrate the magnetic field generated by the magnet, so that the magnetic field can more effectively act on the voice coil 301. The hua si located below the diaphragm 102 cooperates with the magnet 3 and the voice coil 301 and other components to form a complete electromagnetic drive system. When an electric current passes through the voice coil 301, the force generated under the action of the magnetic field can be more efficiently transmitted to the diaphragm 102, pushing the diaphragm 102 to vibrate and make sound, and the stable hua si 2 structure helps to reduce the sound distortion caused by unstable magnetic field and other factors. Magnet 3 is the core component of the entire loudspeaker to generate a magnetic field, which provides a power source for the movement of the voice coil 301. In this structure, clamped between the upper hua si 201 and the lower hua si 202, the hua si 2 guides and concentrates the magnetic field, creating a relatively stable and suitable magnetic field environment around the voice coil 301, ensuring the loudspeaker sound quality and achieving low distortion effect. Magnet 3 interacts with the voice coil 301 clamped between them, according to the principle of electromagnetic induction, when audio current passes through the voice coil 301, the voice coil 301 will be affected by the Ampere force in the magnetic field generated by the magnet 3, and then drive the diaphragm 102 to vibrate and make sound.The stable magnet 3 mounting structure and magnetic field distribution can make the voice coil 301 receive uniform force and move regularly, avoiding the problem of voice coil 301 abnormal vibration caused by uneven magnetic field, which can cause sound distortion. The voice coil 301 is a key component that connects electrical signals and mechanical vibration. It converts the input audio electrical signal into mechanical movement in the magnetic field. The voice coil between the magnets 3 can accurately produce corresponding vibration according to the current change rule when the alternating current passes through, and due to the stable effect of each component in the structure on the magnetic field, the vibration of the voice coil can be more stable and linear. When the audio equipment (such as mobile phones, computers, and audio host computers) outputs an audio electrical signal, the signal is transmitted to the voice coil 301 of the loudspeaker through the connecting line. At this time, the voice coil 301, as the initial component of the received electrical signal, is ready to respond to the change rule of the electrical signal. After receiving the alternating audio electrical signal, the voice coil 301 will generate an ampere force according to the electromagnetic induction principle. The magnet 3 is clamped between the upper and lower washers 201 and 202, and the washer 2 guides and concentrates the magnetic field generated by the magnet, so that the magnetic field acts uniformly and stably on the voice coil 301. The voice coil 301 in this precise magnetic field is accurately driven by different directions and sizes of ampere force according to the frequency, amplitude, and other characteristics of the electrical signal, and starts to produce corresponding mechanical vibration. The vibration of the voice coil 301 is efficiently transmitted to the diaphragm 102 through the connection structure between them, so that the diaphragm 102 can completely receive the vibration characteristics from the voice coil 301. At the same time, the stable connection structure of the bracket 1 and the connecting plate 101 ensures the mechanical stability of the entire device, prevents the transmission path of the force from being disturbed due to loose structure, and ensures that the force transmitted from the voice coil 301 to the diaphragm 102 is accurate. After receiving the vibration from the voice coil 301, the diaphragm 102 starts to vibrate with the same frequency and amplitude as the voice coil 301. The vibration of the diaphragm 102 causes the density change of the surrounding air molecules, forms a sound wave, and spreads to the surrounding space, and finally converts into the sound that people can hear. Due to the stability and accuracy of the structure in each link from the electrical signal to the voice coil 301 vibration and then to the diaphragm 102 vibration, the sound emitted by the diaphragm 102 can restore the original characteristics of the audio electrical signal to the greatest extent, effectively reduce the distortion, and present clear and realistic sound effects.During the whole process of the loudspeaker, the structure design of the bracket 1 inside the front and rear ends matched with the washer 2 clamping the magnet 3, and the bracket 1 inside the bottom and the connecting plate 101 clamping the washer 2 together, continuously ensures the stability of the magnetic field, even in the case of the slight mechanical impact and interference generated by the vibration of the voice coil 301 and the sound of the diaphragm 102, the relative position of each component can be maintained, and the voice coil 301 is always in a stable magnetic field environment, so that the loudspeaker can continuously and stably work according to the above process when the subsequent electrical signal is input, and output low distortion sound.
[0024] In this embodiment of the invention, connecting grooves 203 are provided on both the front and rear sides of the upper end of the upper washer 201 and the lower washer 202. Magnets 3 are located between the connecting grooves 203 of the upper and lower washer 201 and the lower washer 202. There are three magnets 3, forming two clamping surfaces. The voice coil 301 is clamped by these clamping surfaces, and both the upper and lower ends of the voice coil 301 are housed within the connecting grooves 203. This design provides a clear and precise positioning space for the installation of the magnets 3 and the voice coil 301. When assembling the speaker, the operator can accurately place the magnets 3 and the voice coil 301 in their corresponding positions based on the position of the connecting grooves 203, improving assembly efficiency and accuracy. Simultaneously, the connecting grooves 203 restrict the horizontal movement of the magnets 3 and the voice coil 301 to a certain extent, ensuring that the magnets 3 maintain a relatively fixed position between the washer 2, preventing easy displacement due to external vibrations, mechanical forces during speaker operation, or other factors. For the voice coil 301, both its upper and lower ends are housed within the connecting slots. This prevents the voice coil 301 from shifting horizontally during vibration, ensuring a more stable and regular trajectory of its movement in the magnetic field. This helps maintain the stability of the entire speaker structure, thus playing a positive role in achieving low-distortion sound output. The magnets 3 are divided into three. This distribution and layout helps to create a magnetic field environment that better meets design requirements within the space defined by the washer 2. The three magnets 3 form two clamping surfaces. Through reasonable spacing and arrangement, the strength and uniformity of the magnetic field can be effectively adjusted, resulting in a stable and appropriately strong magnetic field within the space where the voice coil 301 is located. This ensures that when the voice coil 301 receives an audio electrical signal and converts it into mechanical motion, the magnitude and direction of the Ampere force it experiences change more precisely and regularly. This makes the vibration of the voice coil 301 more closely match the characteristics of the input electrical signal, helping to reduce sound distortion and improve sound quality. Two clamping surfaces hold the voice coil 301 tightly and precisely, ensuring that the voice coil 301 remains stably within the effective magnetic field area and preventing it from wobbling or deviating from the center of the magnetic field during operation. When driven by an audio electrical signal, the voice coil 301 accurately generates corresponding mechanical vibrations according to the principle of electromagnetic induction within the stable magnetic field environment defined by the clamping surfaces. Furthermore, the clamping action ensures that the relative position of the voice coil 301 and the magnetic field is always in an optimal state, resulting in more stable and linear vibration of the diaphragm 102 driven by the vibration of the voice coil 301. This further improves the quality of the speaker's output sound and achieves low-distortion acoustic performance.
[0025] Working principle: Observe the upper and lower Hua Si 201 and 202, according to the connection groove 203 opened on the upper end of the two sides, accurately put three magnets 3 into the corresponding position, that is, let the magnet 3 be between the connection groove 203 of the upper and lower Hua Si 201 and 202, at this time, the connection groove 203 plays a positioning role, makes the installation position of the magnet 3 accurate and faultless, improves the assembly efficiency. Because the connection groove 203 limits the magnet 3 in the horizontal direction, the magnet 3 can be stable between the Hua Si 2, and is not easy to be displaced by external vibration or mechanical force in the operation process. Place the voice coil 301 between the three magnets 3, so that the upper and lower ends of the voice coil 301 are respectively accommodated in the connection groove 203, at the same time, the voice coil 301 is tightly clamped by the two clamping surfaces formed by the magnet 3. Such installation structure ensures that the voice coil 301 is in the center of the effective action area of the magnetic field when it is initially assembled, and will not be randomly deviated in the horizontal direction, laying a foundation for subsequent stable work. Put the Hua Si 2 with assembled magnet 3 and voice coil 301 into the bracket 1, use the space inside the bracket 1 to carry and preliminarily position it, ensure the accurate position of the Hua Si 2. Then, fix the upper end of the bracket 1 with the connecting plate 101, and make the middle part of the connecting plate 101 and the diaphragm 102 firmly combined during the connection process. At this time, the bottom of the bracket 1 and the connecting plate 101 from the top and bottom directions jointly clamp the Hua Si 2, preventing the Hua Si 2 from shifting in the subsequent work. The front and rear ends of the bracket 1 are matched with the Hua Si 2 to clamp the magnet 3, ensuring that the magnet 3 is always in the set stable magnetic field position. When the external audio equipment (such as mobile phone, computer, sound host, etc.) runs and outputs audio electrical signal, the signal is stably transmitted to the voice coil 301 of the loudspeaker through the adapted connecting line. After the voice coil 301 receives the alternating audio electrical signal, due to its stable magnetic field environment constructed by three magnets 3 and Hua Si 2, according to the principle of electromagnetic induction, Ampere force is rapidly generated inside the voice coil 301. In this process, the Hua Si 2 plays a role of guiding magnetism, guiding and concentrating the magnetic field generated by the magnet 3, so that the magnetic field acts uniformly and stably on the voice coil 301. The voice coil 301 in the accurate magnetic field is accurately driven by different directions and sizes of Ampere force according to the frequency, amplitude and other characteristics of the input electrical signal, and starts to produce corresponding mechanical vibration. Benefiting from the reasonable layout of the magnet 3 (divided into three, forming two accurate clamping surfaces) and the limiting of the connection groove 203 to the voice coil 301, the vibration trajectory of the voice coil 301 is stable and regular, the change of the Ampere force it receives is accurate, and it maximally matches the characteristics of the electrical signal. The energy generated by the vibration of the voice coil 301 is transmitted to the diaphragm 102. The stable connection structure of the bracket 1 and the connecting plate 101 ensures the mechanical stability of the whole device, avoids the interference of structure looseness to the force transmission path, ensures the accurate transmission of the force from the voice coil 301 to the diaphragm 102, and the diaphragm 102 completely receives the vibration characteristics from the voice coil 301. After receiving the vibration, the diaphragm 102 starts to vibrate with the same frequency and amplitude as the voice coil 301 by virtue of its good elasticity and flexibility.The vibration of diaphragm 102 causes changes in the density of surrounding air molecules, forming sound waves that propagate into the surrounding space and are ultimately converted into audible sound. Because each stage, from the electrical signal input to the vibration of voice coil 301 and then to the vibration of diaphragm 102, has a carefully designed structure to ensure stability and precision, the sound emitted by diaphragm 102 can reproduce the original characteristics of the audio electrical signal to the greatest extent, effectively reducing distortion and presenting a clear and realistic sound effect. During continuous speaker output, even if the vibration of voice coil 301 and the sound output of diaphragm 102 may generate minor mechanical impacts and interference, the design of the washer 2 clamping the magnet 3 at both ends of the bracket 1, and the washer 2 being clamped by the bottom of the bracket 1 and the connecting plate 101, continuously ensures the stability of the magnetic field, maintains the relative positions of all components, and ensures that voice coil 301 is always in a stable magnetic field environment. This ensures that when a subsequent electrical signal is input, the speaker can continuously and stably operate according to the above process, stably outputting low-distortion sound.
