Transcript: Aviv Acco Ms. Childress Science I 30/3/2019 Electromagnetic Devices Project Speaker History History of the speakers Since the dawn of history, at least since the dawn of record history, people have sung, played and listened to music. Until the beginning of the twentieth century, the only way to listen to music was to participate in live concerts, including musicians singing and playing musical instruments. Inventors Towards the end of the nineteenth century and the beginning of the twentieth century, a number of inventions were developed, these allowed listening to recorded and reconstructed music. Inventors Alexander Graham Bell The first invention, which is the basis for all the recording and playback systems of music, is the phone. The phone is a device for receiving, transmitting and playing sounds and sounds - or transmitting speech between two points via wires. The invention and development of a number of people paved the way for the invention of the telephone. The improved phone patent was registered by Alexander Graham Bell in the United States in the mid-1870's. Ernst Siemens In 1920, Ernst Siemens released an advanced version of the speakers, that was developed based on a vacuum tube or radio tubes and tubes or valves. This electronic amplification enabled the first electronic recording devices, which were magnetic wire records or wire records, in which the recording was made on a wire of magnetic metal. Function Speakers Function Speakers are a very useful device it's purpose is to take an amplified signal and turn it into sound. The function of loud speaker is to convert an electrical wave into a mechanical wave - sound. Speakers comes in pairs, it allows them to produce stereo sound. Both left and right speakers transmit audio on two separate channels, since we use to hear sounds from the left and right at the same time, by using two speakers, the sound is more natural. How it performs... How it perform Speakers are transducers that convert electromagnetic waves into sound waves. Inside the speaker there is electromagnet: a metal coil which creates a magnetic field when an electric current flows through it. This coil is like a permanent magnet, but it can revers the direction of the current in the coil and flips the poles of the magnet. When the pulses of electricity pass through the coil of the electromagnet, the direction of its magnetic field is rapidly changed. The electromagnet is attached to a cone made of a flexible material than it amplifies these vibrations, pumping sound waves into the surrounding air and towards our ears. Diagram Diagram Uses of Speakers Electric Devices Phones Music Uses Electric Devices Electric Devices There are so many electronic devices who use speakers: from our home stereo - to hear music, listen to the radio, play the computer, or on the big screen - the cinema. Phones and talking devices The telephone was the first invention that used speakers, since then we use speakers to talk and communicate from far or near distances. Phones Live music Today speakers allow us to listen to music in a good quality eve if the singer or band are on the big stage far way. The good qualities of the speakers brings us pure sound from very far away - is if the band is standing just near to us.

Transcript: "This is interesting and such a remarkably simple tool with a great impact. A global basic income will have the wonderful effect of a dynamic and recursive engine for a healthy and thriving global economy, which is working inclusive for everyone. We will finally have new markets to conquer. Look Leila! The higher the transaction volume, the higher the basic income for everyone. The higher the basic income, the higher the turnover for companies, businesses and innovators. A wonderful economic engine!" "For companies this is actually great marketing and improves our reputation. And I just looked at co°open's website and have seen more inspiring "impact marketing" and sponsoring tools" "But co°open is not stopping there, we have dedicated ourselves to raise the basic income steadily. With every month in which our pool is growing, half of the newly generate resources will enlarge the basic income for everyone. Turning 10€ into 11€, 12€, 25€, 100€, 500€, 1000€ etc. Member 3 Customers love what they do and enjoy their innovations... Competitive Differentiators "This is a wonderful and visionary lookout Leila, but do you know, what I believe is the most charming. We can get started today, with almost nothing, we are not dependent on any large technological or systemic changes, to initiate and experience positive progress. All we have to do is to introduce the Social Responsibility Certificate in our companies and we all gain plenty small benefits, step by step. What do you think about starting with a 1% Certificate? Description about this team member. Just give a brief explanation of the member's experience and competencies. Leila and Franz went back home, while reading more about the team of co°open. Summary Source: http://www.mckinsey.com/~/media/mckinsey/industries/financial%20services/our%20insights/how%20the%20payments%20industry%20is%20being%20disrupted/global_payments_2015_a_healthy_industry_confronts_disruption.ashx "Together with other businesses, we will leave our mark as one of the first companies world wide to take part in shaping our evolution at a key turning point in history and secure the global purchasing power of everyone." Description about this team member. Just give a brief explanation of the member's experience and competencies. Ever since he could think Samuel was juggling with numbers and ideas, on how to improve millions of lifes in the most efficient way. Until the day, where he initiate co°open to go all in with his idea. co°open - global basic income Tumblingerstr. 80337 München samuel.andert@coopen.io T: +49 1525 3586734 Leila and Franz are sad, because the potential of reaching many customers with their companies can not be fully embraced, due to the lack of purchasing power. Meet Leila and Franz, two entrepreneurs "co°open is an open organization introducing a global basic income from bottom up for everyone, one person after another, regardless their heritage, race or social state." Social Responsibility 1000€ Member 4 Write down all of the reasons that you are better than the competition here. Leila begun to read out aloud: Once in their beds, they watched a summary, which the found about basic income on youtube, before they fell asleep, very pleased with the new discovery and a smile on their faces. CONTACT US: "Franz, every time we are eating here, 1% of each meal will be payed into a so called global basic income pool, listen to the explanation" Competitors 1% Samuel Andert Martin Luther King Jr. "... each time the pool is reaching a limit of 10€, somewhere in the world a human will be randomly elected to receive from now on every month a mini basic income forever." Easy Market Entry "Customers will enjoy the moment each time they buy something with a smile in their face, because they can see and feel the direct impact, they are generating with their purchase" Jascha "If every company and every person has a Social Responsibility Certificate of just 5%, already today according to the report, every adult could receive a monthly basic income of ~500€. And not the stop there, the financial transaction market is expanding yearly by 5-7%, doubling the transaction volume by 2030" Are there any other people trying to make money from the same market with a similar solution? Description about this team member. Just give a brief explanation of the member's experience and competencies. Certificate Franz begun to smile, it took him a moment to let that sink and sort out his thoughts, then he said to Leila: Leila nodded silently and added: Leila continues to read, with ever growing eyes: 2050 basic income Franz interrupted Leila in her dreams and said: Leila, even more excited, remembers the global payments report from McKinsey & Company and continued to calculate: They have a great expertise in creating new ideas, products and services, which improve our daily lives for the good, but they have a big dilemma: "I am now convinced that the simplest approach will prove to be the most effective -

Transcript: By Ann and Olivia Design Sketch Explore Create Try it Out Make it Better Speaker Presentation While researching for our speaker, we found that sound energy can be chemical, nuclear, gravitational, or mechanical. We also learned sound is produced when something vibrates. The waves travel through a medium such as solids, liquids or gasses. They move through by vibrating the molecules of the matter. To make our design better we would make our sides (the cube) shorter because the relationship between our coil and battery, wasn't close enough. Once Mr.DeVier-Scott & Mr. Stansberry advised us to put our coil and battery closer together. Doing this caused the sound quality became really clear. Final Product Identify the Problem We based our design on the speaker shown to us. We used reverse engineering to discover the purpose of every material we needed to use to create our speaker. We learned that the purpose of the cone was to expand the sound . For our design we used the metal can as our base. We wrapped our coil around the paper tube 60 times. Our challenge was to use reverse engineering to design and build a speaker that can produce audible sound from an iPad or iPod. For our speaker construction, we were limited in materials such as: insulated wire, Scotch tape, a permanent magnet, a 2 oz. tin with it's lid, cardstock, an iPad, iPod, or iPhone, and an amplifier In the Works When we first tested ours out the sound was very dissorted and very quiet. When building our speaker we ran into a couple problems. First off, we had a problem wrapping our coil around the paper tube. We tried upwards of 20 times. Originally, we used the thick wire but, after thinking over why our wire wouldn't stay wrapped wee switched to the thin one. Another challenge we faced was the actual construction of the speaker. We had a problem with the paper cube. When we tested the first time, our sound was very faint. Once we reevaluated our design we figured out the cube was the problem. We made the square shorter and it seemed to work.
