Background

In conventional voice coil designs, the inductance of the voice coil affects the nonlinear inductance variation and harmonic distortion of the magnetic material. At present, some short-circuit rings are used for reducing harmonic distortion, but the short-circuit rings do not take the heat dissipation function into consideration, so that a certain amount of heat can be generated when the loudspeaker works, and the short-circuit rings lacking the heat dissipation function cannot effectively dissipate the heat, which may cause the loudspeaker to overheat under long-time high-power operation, thereby reducing the performance and the service life of the loudspeaker. In high power applications, the speaker may be faced with the problem of power compression, i.e., the output power may not reach the desired level, thereby reducing the sound quality and effectiveness of the speaker. Because of lack of heat dissipation function, the short circuit ring can not effectively reduce the inductance of voice coil loudspeaker voice coil. This results in an increase in the nonlinear inductance variation of the magnetic material, which in turn increases the occurrence of harmonic distortion. This affects the sound quality and audio performance of the speaker. Thus, improvements are needed.

The inside of ring body forms the cavity, neodymium magnet is located in the cavity, the voice coil wire is located the top of neodymium magnet, the washer cover is established the outside of voice coil, the voice coil pipe is located the top of voice coil wire.

Specifically, the ring body of the short circuit ring can be in different shapes and sizes, such as a circular ring shape, a square shape, an elliptic shape and the like, so as to adapt to the requirements of different magnetic circuit systems. The heat dissipation fins of the short circuit ring can be a plurality of, and are connected on the outer wall of the ring body at intervals and extend outwards. The number, shape and arrangement of the radiating fins can be designed according to the specific requirements of the magnetic circuit system so as to provide larger radiating area and radiating effect. The heat sink may have various shapes and sizes, such as rectangular, trapezoidal, bar-shaped, etc., to increase a heat radiating area and improve a heat radiating effect. The shorting ring is located outside the neodymium magnet and the ring body surrounds the neodymium magnet and other magnetic circuit elements. The radiating fin and the ring body are connected together in an integrated forming mode to form an integrated short circuit ring structure. The short circuit ring changes the inductance of the voice coil and reduces harmonic distortion through interaction with a neodymium magnet in the magnetic circuit system, and meanwhile, the heat radiating area is increased due to the existence of the radiating fins, so that heat dissipation is accelerated.

Meanwhile, the radiating area is increased due to the existence of the radiating fins, the radiating effect is improved, and the loudspeaker can bear power better and reduce power compression.

A plurality of cylinders are arranged around the ring body at intervals, and the cylinders are arranged between two adjacent cooling fins.

Specifically, cylinders are introduced as an alternative structure to the shorting ring, the cylinders are disposed between the heat sinks, surrounding the magnetic circuit, a gap is formed between each cylinder and its adjacent two heat sinks, and the number of cylinders may be varied according to specific needs. The main function of the short circuit ring is to reduce the magnetic resistance in the magnetic circuit, thereby improving the performance of the magnetic circuit system. The cylinders act like shorting rings in the preferred construction, they guide the magnetic field flow by providing a low reluctance path. When current passes through the magnetic circuit, the magnetic field will be conducted along the path between the cylinder and the torus, thereby reducing the reluctance. This contributes to an improvement in efficiency and performance of the magnetic circuit system. When the magnetic circuit system is used, a magnetic field is generated by current through the voice coil wire. This magnetic field is conducted into the neodymium magnet and forms a low reluctance loop through the path between the cylinder and the ring body, eventually returning to the voice coil wire, and the introduction of the cylinder provides an additional low reluctance path that allows the magnetic field to flow more efficiently through the magnetic circuit. The performance of the magnetic circuit system can be further improved by introducing the cylinder as a preferable structure. They increase the number of low reluctance paths in the magnetic circuit, reducing the total reluctance of the magnetic circuit. This may increase the efficiency of the electromagnetic device, reduce energy losses, and improve the operational performance of the device. By using a cylinder, more efficient energy transfer and lower heat losses can be achieved.

In some embodiments of the present utility model, the cylinder is made of neodymium magnet

In particular, when the cylinder is made of neodymium magnet, the cylinder can be used as an external magnetic circuit, and has good magnetic performance. In a magnetic circuit system, when a current passes through a voice coil wire to generate a magnetic field, the magnetic field is conducted to a cylinder in a neodymium magnetic material. Due to the high magnetic permeability and high remanence induction strength of neodymium magnets, the cylinder can effectively absorb and guide a magnetic field to form a low-reluctance loop. When the magnetic circuit system is started, current passes through the voice coil wire to generate a magnetic field. This magnetic field is conducted into a cylinder of neodymium magnetic material, which absorbs and directs the magnetic field, forming a low reluctance circuit. The gaps between the cylinders allow the magnetic field to propagate between the cylinders, further reducing the reluctance. The neodymium magnetic material has high magnetic conductivity and high remanence induction intensity, and can effectively absorb and guide a magnetic field. By introducing the neodymium magnetic cylinder into the magnetic circuit system, the magnetic field can flow more effectively, and the magnetic resistance is reduced, so that the efficiency of the magnetic circuit system is improved. The cylinder is used as a part of neodymium magnetic material, so that a low-reluctance path can be formed in the magnetic circuit system, and the magnetic field can be conducted more smoothly. This helps to reduce energy losses and improve the energy efficiency performance of the electromagnetic device.

In some embodiments of the utility model, the material of the shorting ring is copper or aluminum.

In particular, when the material of the short-circuit ring is copper or aluminum, they have good conductive properties. In the magnetic circuit system, when current passes through the voice coil wire to generate a magnetic field, copper or aluminum materials in the short circuit ring form a magnetic field conductor with low impedance. The magnetic field forms a closed loop in the copper or aluminum shorting ring, thereby reducing magnetic resistance and promoting smoother magnetic field flow. When the magnetic circuit system is started, current passes through the voice coil wire to generate a magnetic field. The magnetic field forms a closed loop in the copper or aluminum short circuit ring, and the magnetic field passes through the short circuit ring, so that the magnetic resistance is reduced, and the magnetic field distribution is improved. The copper or aluminum short circuit ring is connected with other magnetic circuit system components and is fixed in the magnetic circuit system through proper connection means. Copper or aluminum has good conductivity and can form a low-impedance magnetic field conductor as a material of the short-circuit ring. By introducing a copper or aluminum short circuit ring into the magnetic circuit system, the magnetic field can be conducted more smoothly, the magnetic resistance is reduced, and the efficiency of the magnetic circuit system is improved. The copper or aluminum material of the short circuit ring can form a closed magnetic field loop, so that the distribution of the magnetic field is improved. The magnetic field can be absorbed and guided, so that the magnetic field distribution is more uniform, the leakage and diffusion of the magnetic field are reduced, and the working stability and performance of the magnetic circuit system are improved. Copper or aluminum has good heat conducting properties. When the short circuit rings are made of materials, the short circuit rings can effectively conduct and emit heat generated in the magnetic circuit system. This helps to reduce the device temperature and improve the heat dissipation and thermal stability of the device.

In some embodiments of the utility model, the T-shaped iron comprises a transverse portion and a vertical portion vertically arranged above the center of the transverse portion, a neodymium magnet, a voice coil tube, a washer and a short-circuit ring, wherein the ring body is sleeved outside the vertical portion and is positioned above the transverse portion, and the neodymium magnet is positioned above the transverse portion.

Specifically, the T-iron includes a transverse portion and a vertical portion vertically disposed above the center of the transverse portion. T-iron is a magnetic structure for a speaker, which functions to guide a magnetic field and enhance the generation of sound. The heat sink in the shorting ring can effectively disperse heat, preventing the neodymium magnet from overheating. This helps to preserve the performance and lifetime of the neodymium magnet and ensures a long-term stable operation of the loudspeaker. The stability and reliability of the speaker system can be improved by optimizing the magnetic circuit system and controlling the heat dispersion. It can reduce performance attenuation and damage caused by temperature and prolong the service life of the loudspeaker.

In some embodiments of the utility model, the voice coil tube is located inside the basin frame, the basin frame is located above the T iron and the short circuit ring, and a cone is arranged inside the basin frame.

In particular, the cone frame refers to a frame or structure that supports the cone, which is typically made of a sturdy material to provide adequate support and stability, and the primary function of the cone frame is to secure and support the cone and place it in position for effective sound amplification and transmission. The basin stand may be made of metal, plastic or any other suitable material to provide sufficient strength and rigidity. The tub may be circular, square or any other suitable shape to accommodate the size of the tub and the design of the speaker system. The basin stand can be kept stable by using supporting legs or other supporting structures, so that the paper basin can be kept balanced and positioned correctly. The cone is positioned in the basin frame and is supported by the basin frame. The basin stand is positioned above the T iron and the short circuit ring and is fixed relative to the positions of the T iron and the short circuit ring. The basin frame is connected with other components (such as voice coil tube, T iron, etc.) of the loudspeaker by a proper connection mode so as to ensure the stability and coordination of the whole loudspeaker system. When an electrical signal in the speaker system generates a magnetic field through the voice coil tube, the magnetic field interacts with the neodymium magnet, thereby generating a vibration force. These vibration forces are transferred to the cone through the basin stand, so that the cone generates corresponding vibration. The vibration of the cone changes the pressure in the air, ultimately producing sound. By inputting an electrical signal into the speaker system, the electrical signal generates a vibration force through the action of the voice coil tube and the neodymium magnet. These vibratory forces are transferred to the cone through the frame, causing the cone to vibrate and produce sound.

In some embodiments of the utility model, a gasket is arranged above the basin frame, and the gasket is fixedly connected with the upper end of the basin frame.

In particular, the spacer is an element located in the speaker that functions to provide support and isolation to ensure proper operation and performance of the speaker. The preferred configuration of the gasket may be selected according to particular needs and design requirements. In this case, the material and shape of the spacer should take into account its required support, insulation and stability. The following are several alternative preferred structural examples: one common gasket construction is made of foam materials, which have good elastic and insulating properties and provide effective support and shock absorption; rubber gasket: the rubber has higher elasticity and durability, and can provide good isolation effect; elastic fiber gasket: such gaskets have excellent insulating properties and durability. The gaskets can be selected and replaced in the design according to specific requirements, and can be fixedly connected with the upper end of the basin stand so as to ensure the stability and the reliability of the loudspeaker. The gasket is positioned above the basin frame of the loudspeaker and fixedly connected with the upper end of the basin frame, provides a contact surface with the basin frame and plays a role in supporting and isolating.

The gasket works on the principle that the gasket protects the structure and components of the speaker from vibration and vibration by providing a gasket and an isolation effect, and it can reduce external interference and resonance and improve sound quality and performance stability of the speaker. When the loudspeaker is operated, the gasket is tightly connected with the basin frame, so that the structural stability of the loudspeaker is ensured, and the gasket can absorb and dampen the impact and vibration from the outside and avoid the impact and vibration from being transmitted to other parts of the loudspeaker.

In some embodiments of the present utility model, a dust cap is disposed in the middle of the cone, and the dust cap is located above the voice coil pipe.

Specifically, the dust cap is used for protecting the voice coil pipe from invasion of dust, foreign matters and moisture, and plays roles in adjusting air flow and protecting tone quality. The dust cap in the preferred structure is positioned above the voice coil tube and has the main function of preventing impurities such as dust from entering the loudspeaker from the top of the voice coil tube. The dust cap may be made of a flexible material such as a rubber basin. The voice coil pipe has a circular cap-shaped appearance, is matched with the diameter of the voice coil pipe, and is fixed at the top of the voice coil pipe. The dustproof cap is positioned above the voice coil pipe and is tightly connected with the voice coil pipe. It covers the whole voice coil pipe top and forms a sealed space with the voice coil pipe. The dust cap is secured to the top of the voice coil tube by an adhesive or other securing means. This ensures a tight bond of the dust cap with the voice coil tube to prevent dust and debris from entering the interior of the speaker. The working principle of the dustproof cap is to prevent external dust, foreign matters and moisture from entering the voice coil pipe and the magnetic circuit system when the loudspeaker works. It protects the voice coil wire and the magnetic circuit element from normal operation while preventing noise and deformation. Through the use of the dustproof cap, the internal components of the loudspeaker are effectively protected from being invaded by dust and sundries, the service life and performance stability of the loudspeaker are improved, noise and distortion of the dustproof cap can be reduced, and clearer and accurate sound output is provided.

In some embodiments of the present utility model, an elastic wave is disposed on the outer side of the voice coil tube.

The elastic wave is positioned on the outer side of the voice coil pipe and is tightly attached to the surface of the voice coil pipe, and the elastic wave is not actually and physically connected with the voice coil pipe, but is fixed on the voice coil pipe through electrostatic adsorption or adhesion and other modes. When an audio signal is transmitted through the voice coil tube, a magnetic field is generated by a current in the voice coil wire. This magnetic field interacts with the projectile to cause the projectile to vibrate. The vibration of the elastic wave is transmitted to the air, thereby generating sound. When the loudspeaker is used, the magnetic field intensity and the change speed in the voice coil wire can be controlled by controlling the current magnitude and the frequency of the audio signal, so that the vibration state and the frequency of the flick wave are controlled, the required audio effect is realized, and the sound generating effect of the loudspeaker can be enhanced by setting the flick wave. It can increase the vibration area and improve the sound production efficiency and quality of sound. Through adjusting the shape, material and position of the elastic wave, the frequency spectrum characteristic of sound can be changed, the sound effect expression of a specific frequency band is enhanced, and clearer and vivid audio experience is provided. The elastic wave can also reduce resonance phenomenon and avoid unnecessary noise and distortion. In general, the arrangement of the damper can improve the sound quality and the volume output effect of the speaker.

In summary, the utility model reduces the inductance of the voice coil by arranging the short circuit ring, thereby reducing the nonlinear inductance variation of the magnetic material, reducing the occurrence of harmonic distortion, increasing the heat dissipation area by the sheet structure of the fin type aluminum short circuit ring, and more rapidly dissipating the generated heat by the fin type aluminum short circuit ring when the loudspeaker works, thereby effectively improving the heat dissipation effect of the loudspeaker. This enables the speaker to withstand more power and reduces the degree of power compression.

The foregoing is only illustrative of the principles and preferred embodiments of the present utility model. It should be noted that several other variants are possible to those skilled in the art on the basis of the principle of the utility model and should also be considered as the scope of protection of the present utility model.
