If you want to learn how to make a column for the phone with your hands, then this guide is for you.
To do this you will need:
1. Housing.Many people use the old speakers from the computer.It is best suited parts made of wood, as this material will absorb sound, which means that the sound will be of higher quality - with no rattles or foreign interference.
2. Chips.Before you make a column for your phone, you need to take care of the acquisition of chip TDA2003 or its equivalent.If there is none, you can use K174UN14.
3. Capacitors capacity of 470 mF (1 pc.), 0.1 uF (1 pc.), 10 mF (1 pc.), 100 mF (2 pcs.).It should be borne in mind that they must be the voltage of 16 volts or higher.If the voltage is higher, the power consumption will increase.
4. Resistors, 3pc 1 ohm, 10 ohm, 1 k.
5. Speaker.Before making a column for the phone, of course, necessary to select the speaker.As such, you can use the speaker of the car, for example, the system PIONEER.For such an amplifier the best possible resistance to 8 ohms.
6. Power supply.It is recommended to take the batteries from the phone.
7. Plug 3.5 mm wire, electrical tape.
8. Solder and soldering iron.
Following the acquisition of the necessary details should be prepared workplace.It is recommended to remove any objects that they do not interfere during the brazing.
So, you start to build.It is recommended to make a mono amplifier, because it consumes very little energy.And before you start doing a column on the phone, it is worth remembering the volume ratio of the highest quality and economical energy consumption.
To start take care of the food.You can take several batteries (eg, 3) and collect them in the usual way.After that, take the connector for the power supply.Alternatively, you can take it from Nokia.We isolate and solder it to the wire from the battery.
How to make a column for the phone that she made quite a loud sound?You will need an amplifier.This - the most difficult part of the job.It is best to collect it on the circuit board, but you can do without it.Instead, you can use such a conventional cardboard.To do this, pierce holes in it and to fix the details of connecting them with thin wires.Do not forget to attach a cable with plug to the amplifier.Plans for the amplifier you can look in the literature or on the Internet in various forums.
very important to know that we can not delay the soldering parts.In this case, it is likely to overheat the elements and they will last long.
Then cleanse the body and is attached to the speaker, connect it to an amplifier.The battery must be secured.Carefully place into the housing so that the cables do not bend or twist.Also, do not forget to pull the plug through the hole in the column.
So we looked at how to make a column for the phone with your hands.Finally it should be added that the desired structure can be attached to the radiator to your circuit is not overheated and will serve you for a long time.
Enjoy your listening!
