Audio Speaker

How to make your own Audio Speakers?

1.   Abstract

        

  The people around the world must be have time as some of them like do this and those. In that thing, we have audio amplifier which it is a part of relaxing after works or stress or bored. Relaxing is really important due to it can make people have their long life and increase their younger. Type of music is important too, it can make the people like and love to listen it when it sound well or we can say it sound attack (attractive) people feels. Audio amplifier more and more develops to providing to the user. To provide the user, the producer needs to increase their quantity as speakers and amplifier. In our proposal just want to build the best IC to control the audio amplifier and high quantities. Now we have no enough components, so we just want to design the kind of IC like KA2209 that we can use it to reduce noise and increase bass boots by increase the capacitor. We know that if we success of building that kind IC are sounder good. Now just face with that IC which do it the best sounds. Finally, we will get the best audio amplifier that it is the people favorite. It will get more interesting from the customer and also has the challenging when it is popular.

2.  Introduction

    As we know, people don’t know what kind of IC that they will using due to it’s the big problems that people difficult to choose and which they used to get a good sound when it output. Concerning to of IC is the IC, we have the type KA2209. It also has a good sound. It made from lots materials as a switch of the transistor was combined to get the best IC. The transistor must be combined to get high and good quantity. We knew that the transistor has lots of types, so we need to choose which one is the best to build the IC. After that, the capacitor also more important to work with IC of the amplifier. We also need to combine it with capacitor and resistance or the others components to get the best sound which it IC required. In fact, an audio amplifier is really important in the other countries due to they want to relax or reduce their stress. So, if the amplifier has a good sound it will have lots of the customer and challenger. 

3.  Material and Methods

    

    Depend on the datasheets we can know that for the circuit stereo of that IC, it needed capacitor 100uF on it pin 5 and pin 8. And about pin 6 and 7, it needs resistance that it makes a good sound. -IC KA2209 it is the IC that converts or widen the signal from small to big signal. -Capacitor 470uF is the main point too. When the capacitor big values, the frequency will low that makes the sound is good. -We used speaker 6 Ohm, speaker is also important to makes sound of audio better in listening.

4.   Experiment and Results

    When we have an experiment, we can know that the IC need the different capacitor to complete it sound. Especially, the capacitor which used to increase sounds of the audio. When we use the capacitor 100uF on pin 1 and pin 3 we get it results is light sounds and after that, we decide to change the capacitor by using 470uF, we know that the sound is heavier and bass boots. So, we just change that only capacitor which made our speaker get the best sound. In the same time, we also used the capacitor non-polar to block DC and also reduce the noise to get clear sound. 

5.   Discussion

    We have discussed with each other already when we have the problem with that audio, we have met different sound when we changed the capacitor. So, we decided to change the capacitor which has the best sound that made our audio like speaker had corporate together. Meanwhile, if we have the afford to buy the best speaker, we will get a really nice speaker.

          6.  Conclusions

    Depending on the results and discussion we have got the best audio amplifier and we have more an opinion to create the best another audio. We hope that we will create another hardware that related to that kind IC which we know it clearly. Although now we have it not the best sound, we will design it more than this latter.
