The main body likely houses the bass speaker and the batteries, along with the assembly to make the top disc rise. From the video and their specifications, the tweeter speaker is inside the the disc at the top, which also houses the bluetooth and driver. I'm quite sure that there is also a small battery in the top which recharges by induction when it is not in levitation (again inferred from their specifications). Due to the levitation height it would be impractical to power the top disc while it is hovering.As for the hovering mechanism, it's probably simply made by a rotating magnet assembly (or more) at the top of the cylinder, which induces eddy currents in the aluminium disc causing it to float. Again nothing special here, just a party trick. The main claim by the product is "Mars’s levitating 360º sound projection reduces sound wave absorption into surfaces by levitating above the subwoofer charging station." Here are some of my reservations.When I built a pair of speakers a while back, I found that it was very important to design the actual enclosure around the speaker cone properly, especially for the woofer. If you look at most woofers, they have a port built into the enclosure. This port is not simply a hole, but rather has a depth of certain dimensions. The system can be modeled like a mass spring system where the port holds a mass of air. This in turn amplifies the bass at select frequencies. You can convince yourself that this works by covering the bass port of your speaker, or simply removing the speaker from its enclosure and listen to how poor it sounds. So the Mars system at least gets this right - the bass speaker is on the ground with a reasonably sized enclosure, so I have no doubt it'll sound fine.The tweeters on the other hand are easier to position because they aren't so sensitive to enclosure design, so I can believe that the floating tweeter will sound fine as well. However, I'm not convinced about 'sound wave absorption' as their claim, nor with dramatically improved sound quality (especially now you essentially only get mono sound - but hey good reason for them to make more $ off you by selling you two). Not to mention the additional sound from the (probably) rotating magnet assembly to levitate

Acoustic Levitation - Levitating Objects Using Sound Waves

Dynamic reconfigurability and higher resolution. Additionally, 3D-printed components are being used to create acoustic holograms or metasurfaces that can manipulate sound waves with even greater precision.In the future, we can expect to see acoustic levitation play a critical role in the construction and resource utilization of off-world colonies. On the Moon or Mars, where gravity is significantly weaker than on Earth, this technique could be used to handle and process raw materials extracted from the local environment. This in-situ resource utilization (ISRU) is a key component of sustainable space exploration, as it reduces the need for transporting materials from Earth.Moreover, acoustic levitation could enable new forms of construction in space. Imagine building structures without the need for traditional scaffolding or support systems, where materials are manipulated and assembled using sound waves. This could lead to novel architectural designs that are not possible in Earth’s gravity.The integration of acoustic levitation with other technologies, such as 3D printing, is also an exciting area of research. Companies like Boeing are already exploring the concept of 3D printing while levitating objects, which could revolutionize the way we construct complex components in space.As we continue to push the boundaries of what is possible in space, technologies like acoustic levitation are becoming increasingly important. They offer a glimpse into a future where space manufacturing is not just a necessity but a norm, where we can build, repair, and sustain ourselves in the vast expanse of space without the constraints of Earth’s gravity.In conclusion, acoustic levitation is.

Acoustic Levitation: Floating on a Wave of Sound

As we venture deeper into space, the challenges of manufacturing and handling materials in microgravity environments become increasingly complex. One innovative technique that is gaining significant attention is acoustic levitation, a method that uses sound waves to manipulate objects in a contactless manner. This technology has the potential to revolutionize how we build and repair in space, and it’s an area of research that is both fascinating and crucial for future space missions.Acoustic levitation works by utilizing high-intensity sound waves to create areas of high and low pressure in a medium, such as air or another fluid. These pressure fluctuations form standing waves, with nodes and antinodes that can trap objects, suspending them in mid-air. This technique is particularly useful in space where gravity is minimal or nonexistent, as it allows for the handling of delicate objects without the risk of surface contamination or damage.In the context of space manufacturing, acoustic levitation is being explored as a key tool for additive manufacturing processes, such as selective laser melting (SLM). On Earth, SLM relies heavily on gravity to keep the powder and printed parts in place, but in microgravity, this is not possible. Here, acoustic levitation steps in as a fixtureless handling mechanism, enabling the manipulation of powder materials and the fusion of raw material with the print part in a continuous manner.Experiments conducted in drop tower facilities and other microgravity environments have shown promising results. Researchers have successfully manipulated polymer powders using acoustic fields, melting the levitated material in the Monks, who sent sound vibrations to the pit, a reflector of these vibrations. That’s what lifted the boulder 400 meters! The sounds rose smoothly (four minutes, or 240 seconds), were beautiful enough, and the vibrations were harmonious. The result was such a creative effect. It was a creative effect because a sacred temple was being built!The stone took off along a parabola – at first, it went almost vertically (vibrations, reflecting off the rock, did not allow the boulder to approach it), then it began to deviate toward the top. Closer to the rock stood a smaller number of monks on the lines-radiuses, hence, vibrations and their reflections were weaker, and to the top, their number at all began to fall sharply, and the stone, following the path of least resistance, exactly got to the place of erection of the sanctuary!It is likely that in the same way, the ancient builders of the pyramids and other global structures moved unbearable boulders for considerable distances and great heights.To get the latest stories, install our app here.A triumphant experimentPhysicists, in general, allowed the possibility of the existence of controlled acoustic levitation. Not only that, they mastered the technology to control it first in one and then in two planes.Probably, many people had a chance to see macrofilming with a water droplet hovering in the air. Such experiments were performed, for example, by scientists from Switzerland. But nobody managed to achieve three-plane control of the process for a long time.And specialists from the University of Tokyo Yoichi Ochiei, Takayuki Hoshi and Yun Rekimoto made small objects of different shapes and weights float in space with the help of sound waves. Japanese matrices of directional sound emitters, located at specific points, allow them to move along complex trajectories.At first, scientists operated with already familiar water droplets, pieces of polystyrene 0.6 to 2 millimeters in diameter, and small radio elements, but the crowning moment of the series of experiments was when a child’s constructor cube was placed on top of a toy pyramid.Realities and prospectsJapanese experts say that their system of manipulating objects in space has two original features. The force acting on an object is the result of the addition of several directed beams of ultrasonic waves. This produces a standing sound wave and captures its minima and maxima at strictly defined points in space. Using one or more directional emitters, the Japanese change the parameters of this standing sound wave, forcing it to move in space on the trajectory they need, which leads to the movement of the object held by the wave.Specifically, the experiments used four speakers that emit sound waves of over 20 kilohertz, which are inaudible to the human ear

Let's dive in!Understanding Magnetic LevitationBefore we get into the nitty-gritty of building your own levitation device, it's important to understand the science behind it. Magnetic levitation, or maglev, uses magnetic fields to counteract the force of gravity. This is the same principle used in maglev trains, which can reach incredible speeds without the friction of traditional wheels.The basic idea is to create a stable magnetic field that can suspend an object in mid-air. This requires a balance between the attractive and repulsive forces of magnets. It's a delicate dance, but once you get it right, the results are mesmerizing.Types of Magnetic LevitationThere are several types of magnetic levitation, but for our DIY project, we'll focus on two main types:Static Levitation: This involves using permanent magnets to create a stable levitation effect. It's simpler but less versatile.Dynamic Levitation: This uses electromagnets and sensors to actively control the levitation. It's more complex but offers greater control and stability.For beginners, static levitation is a great starting point. It's easier to set up and doesn't require advanced electronics.Materials NeededTo build a

Simple magnetic levitation device, you'll need the following materials:Neodymium magnets (strong rare-earth magnets)A non-magnetic base (like a wooden or plastic board)A levitating object (a small, lightweight magnet or magnetic material)Super glue or hot glueA ruler and a pencilYou can find most of these materials at a local hardware store or online. Neodymium magnets are particularly strong, so handle them with care to avoid pinching your fingers.Designing Your Levitation DeviceThe design of your levitation device will depend on the type of levitation you choose. For static levitation, the design is relatively simple. You'll need to arrange the magnets in a way that creates a stable magnetic field.Choosing the Right MagnetsThe key to successful levitation is choosing the right magnets. Neodymium magnets are ideal because they are incredibly strong and small, making them perfect for DIY projects. You'll need at least two magnets: one for the base and one for the levitating object.When selecting your magnets, consider the following:Strength: The stronger the magnet, the more stable the levitation. However, stronger magnets can be more difficult to handle.Size: Smaller magnets are easier to work with, but you may need more of them to achieve stable levitation.Shape: Disc or cylinder-shaped magnets are typically easier to work with for levitation projects.Arranging the MagnetsThe arrangement of your magnets is crucial for achieving stable levitation. Here are a few tips to get you started:Place the base magnet on a non-magnetic surface, such as a wooden or plastic board.Position the levitating magnet above the base magnet, ensuring the poles are aligned to create a repulsive force.Adjust the distance between the magnets until you find a stable point where the levitating magnet hovers in mid-air.This process may take some trial and error. Be patient and make small adjustments until you achieve the desired effect.Building Your Levitation DeviceNow that you have your materials and design in place, it's time to build your levitation device. Follow these step-by-step instructions to bring your project to life.Step 1: Prepare Your BaseStart by preparing your non-magnetic base. You can use a wooden or plastic board. Make sure it's sturdy and flat to provide a stable surface for your magnets.Using a ruler and pencil, mark the positions where you will place your base magnets. Ensure they are evenly spaced and aligned to create a balanced magnetic field.Step 2: Attach the Base MagnetsOnce you have marked the positions, attach the base magnets to the board using.

Super glue or hot glue. Make sure the magnets are securely attached and aligned with your marks.Step 3: Position the Levitating MagnetNow, it's time to position the levitating magnet. Hold it above the base magnets and slowly adjust the distance until you find a stable point where the magnet hovers in mid-air.This step may require some patience and fine-tuning. Make small adjustments and observe how the magnet reacts. The goal is to find a balance where the repulsive force of the magnets counteracts the force of gravity.Step 4: Fine-Tune and TestOnce you have achieved stable levitation, it's time to fine-tune and test your device. Make sure the levitating magnet is centered and stable. You can gently tap the base to see if the magnet returns to its original position.If the magnet is not stable, try adjusting the position of the base magnets or the distance between the magnets. It may take a few attempts to get it just right.Troubleshooting Common IssuesBuilding a levitation device can be challenging, and you may encounter some issues along the way. Here are some common problems and solutions to help you troubleshoot:Magnet Won't LevitateIf your magnet won't levitate, it could be due to a few reasons:Magnet Strength: Ensure you are using strong neodymium magnets. Weaker magnets may not provide enough repulsive force.Magnet Alignment: Check the alignment of your magnets. The poles should be aligned to create a repulsive force.Distance: Adjust the distance between the magnets. If they are too close or too far apart, they may not achieve stable levitation.Magnet is UnstableIf your magnet is unstable and keeps wobbling or falling, try the following:Center of Gravity: Ensure the levitating magnet is centered above the base magnets. An off-center magnet can cause instability.Base Stability: Make sure your base is flat and stable. Any movement or vibration can affect the levitation.Fine-Tuning: Make small adjustments to the position of the base magnets or the distance between the magnets until you achieve stability.Advanced Levitation TechniquesOnce you've mastered the basics of magnetic levitation, you may want to explore more advanced techniques. Here are a few ideas to take your project to the next level:Electromagnetic LevitationElectromagnetic levitation uses electromagnets and sensors to actively control the levitation. This method offers greater control and stability but requires more advanced electronics and programming.To build an electromagnetic levitation device, you'll need:ElectromagnetsSensors (such as Hall effect sensors)A microcontroller (such as Arduino)Power supplyWiring and soldering equipmentThe basic
