The science behind how speakers transmit sound

There are several devices that we use in our daily life that produce the sound such as a Radio, headphone, television, phone, intercom etc. but have you ever thought of taking a look at the science that is working behind all this process? Most of the people never think of focusing on such things because they think they are not supposed to think about such things but there are some people that are crazy to learn the science behind everything they use in their daily life.

This craze is the only thing that has brought you to this article. Today, we’re going to show you the way a speaker transmits the sound. All the devices that you use in your daily life such as headphone, computer, phone, television etc. have a speaker installed in them and that speaker is used to generate the sound that you hear.

The thing is that how a speaker converts the electromagnetic field to the sound that we actually hear. Well, today we’re going to take a look at this fact and it is going to very interesting.

Turning electricity into sound

The vibration of the things makes the sounds that we hear in our daily life. Most of the times, the sound is invisible but in some special cases, we can actually see it. If you thump a stick on the kettle-drum you’ll be able to see the movement of the skin of drum which generates the sound. The same science works behind the speakers.

There is a lightweight metal cone, paper, plastic or fabric at the front of a loudspeaker. The loudspeaker’s circular metal rim is attached to the cone. And the inner part of the cone is fixed to an iron coil. The coil is turned into a magnet or electromagnet when the loudspeaker is hooked up to the stereo. The electromagnet either repels or attracts the permanent magnet according to the flow of electricity in the cables.

The loudspeaker’s cone is moved with this process as the coil moves back and forward. The moving cone generates sounds in the air like the vibration of the drum skin back and forth. If you’re looking to take a deeper look at the science behind this process, you may take a look at MyGoldeni review.

Making sounds of different volume

The loudspeaker makes a louder sound when the bigger pulse of electricity is sent to the loudspeaker and similarly the smaller pulses of electricity make the quieter sounds. We have to create a vibration with lots of energy if we want to make a loud sound. The movement of bigger speakers is slightly different from the movement of smaller speakers.

Smaller speakers are good for producing lower frequencies. The back and forth movement of any speaker can produce different kinds of frequencies.

In-depth guide to the math behind actually winning the lottery

Winning a lottery is a dream of everybody’s life because it helps you live a life that you have always dreamt of. Everybody loves to live a life where they can enjoy all the comforts of life but only a few can live such a life. Some of the people work hard in their life to live such a comfortable life while others use some tricks to become rich and live a comfortable life.

The lottery is one of those tricks that can help you become rich overnight. The best thing about the lottery investment is that it is a legal business and you’re not going to face any problem after investing your money in this business. The problem with this business is that most of the people don’t understand the techniques and algorithms working behind the system.

It is a concept of most of the people that lottery is just a game of luck where the lucky one wins the game while all the other lose their money. This concept is wrong because there are several top billionaires that became rich by understanding the technique that works for the lottery system.

In this guide to Thai lotto, we’re going to show you the ways that can help you understand the technique working behind the lottery.


There are several algorithms involved in the process of the lottery. You need to understand the basic algorithms before investing your money in a lottery system. No one will ever teach you these algorithms because everyone wants to keep the ball in his own court. You need to understand the algorithms by yourself.

You need to run a deep research on the lottery system so that you may understand the criteria working behind this system. You should avoid spending your money on a lottery that you cannot understand.

Investing minor amount

Once you realize that you have understood the method working behind the lottery, you should invest your money gradually. If you consider investing all the money at once, you’ll fail to get the benefits. A minor mistake in your calculation can make you lose the entire money. You need to think and act wisely. The best way to invest your money is to start with a minor. If your trick works, then you should gradually increase your investment.

Previous Results

Taking a look at the previous results of the lottery helps you understand the method that they are using to prepare the results. The result preparation is a difficult process and it requires a little bit mathematical knowledge. If you have good knowledge of math, you’d easily be able to understand that process working behind the preparation of the results of a lottery.

What Type Of Car Battery Should You Get?

The first time I bought a car, I was only in my late teens. Back at that time, I did not know much about the vehicles and their maintenance. As expected, the car did not last long, but it managed to cruise me through the entire high school years. I was adamant that I will not purchase another till I have acquired the basic details about the automobiles. So, I took a job in a garage as an intern.

The money that I earned was only a bonus as my primary interest was in knowing about the cars and their features. For instance, it actually takes a lot of time before you understand the nuances of the different car battery types available on the market. In this article, you will get an in-depth view about the various kinds of car batteries.

Wet of Flooded car battery – this is perhaps the most popular kinds of car batteries available in the market. People from all walks of life can make use of these cells as they are not very expensive. The design of the cells is done in such a manner that the plates stay suspended. Each plate is separated from the other carefully. As the casing of the battery is completely sealed, the leaking of gasses is not possible. The fluid stored inside the cell will only last till the battery is working. You will not have to invest too much time in its maintenance.

Calcium-Calcium car battery – if you are looking for a car cell that has a low self-discharge rate then this is the best option for you. This type of battery makes use of the calcium alloy. This alloy is connected to a different charged plate. If you are using this battery, then you will have to make sure that you are not overcharging it. Overcharging damages all the plates. The reason for putting the calcium alloy is that it will make the mixing of fluids and liquid-loss less.



Valve Regulated Lead Acid car battery – or the VRLA have become popular in the recent times. As the name suggests, the battery is fitted with some safety valves, which have been adequately pressurized. This particular battery can be further divided into two kinds – the GEL and the AGM. Though these batteries are not very big, they will provide the driver with the required power.

Deep Cycle car battery – if you are looking for a battery that will provide you with adequate power for a longer duration, then the deep cycle car batteries will be your ideal choice. These batteries are mainly fitted to the golf carts, boats of small size and electrical vehicles. These cells are also utilized for the collection and storing of the wind and solar powers. The plates in these batteries are thick.

Lithium Ion car battery – these kind of batteries are not very common. Only some exclusive vehicle and cars with high performance make use of these cells. The cost of these batteries is very high, and this is the reason why regular cars are not installed with these cells. The power that they produce is very high and lasts for a significant period.
