If you want to learn how to make a speaker for your phone with your own hands, then this guide is especially for you.
For this you will need:
1. Frame. Many people use old speakers from the computer. Parts made of wood are best suited, since this material will absorb sound, which means that the sound will be better - without rattling and extraneous interference.
2. Microcircuits. Before you make a speaker for your phone, you need to take care of purchasing a TDA2003 chip or its equivalent. If one is not available, then K174UN14 can be used.
3. Capacitors with a capacity of 470 mF (1 pc.), 0.1 mF (1 pc.), 10 mF (1 pc.), 100 mF (2 pcs.). It should be borne in mind that their voltage should be from 16 volts and above. If the voltage is higher, the power consumption will increase.
4. Resistors, 3pcs: 1 Ohm, 10 Ohm, 1 kOhm.
5. Speaker. Before you make speakers for your phone, of course, you need to choose a speaker. As such, you can use a speaker from a car, for example, a PIONEER system. Forof such an amplifier, the most optimal resistance will be 8 ohms.
6. Source of power. It is recommended to take rechargeable batteries from your phone.
7. Plug 3.5 mm, wires, electrical tape.
8. Solder and soldering iron.
After purchasing the necessary parts, you should prepare the workplace. It is recommended to remove all foreign objects so that they do not interfere during soldering.
So, you start assembling. It is recommended to make a mono amplifier as it consumes very little power. And before you start making speakers on your phone, you should remember the ratio of the highest quality volume and economical power consumption.
First, let's take care of the food. You can take several batteries (for example, 3) and assemble them in the usual way. After that, we take the connector for the power supply. Alternatively, you can take it from Nokia. Isolate and solder the wire from the battery to it.
How to make a speaker for the phone so that it makes a loud enough sound? This will require an amplifier. This is the hardest part of the job. It is best to assemble it on a printed circuit board, but you can do without it. Instead, you can use ordinary cardboard. To do this, it is necessary to pierce holes in it and fix the parts by connecting them with thin wires. Don't forget to connect the wire with the plug to the amplifier. Circuits for the amplifier can be searched in specialized literature or on the Internet in various forums.
Veryit is important to know that you can not tighten the soldering of parts. In this case, there is a possibility of overheating of the elements, and they will not last long.
After that, we clean the case and fix the speaker there, connect it to the amplifier. Next, attach the battery. We carefully place it in the case so that the wires do not bend or twist anywhere. Also remember to pull the plug through the hole in the speaker.
So, we looked at how to make a speaker for your phone with your own hands. Finally, it is worth adding that, if desired, a radiator can be attached to the structure so that your circuit does not overheat and serve you for a long time.
Enjoy your listening!
