Unfortunately, not every one of us can afford to have a high-quality speaker system in the house. Now even the cheapest option will cost at least 10 thousand rubles. However, not to buy low-quality speakers that make a squealing sound? If you are so eager to have your own speaker system in your home , you can do it yourself.
Moreover, all the suitable parts and elements can be purchased almost anywhere, and their cost will certainly not be 10 thousand rubles. How to make a
speaker system with your own hands? You will learn about this from our article today.
Tool preparation
So, during the work we will need the following materials and tools:
- screwdriver;
- chipboard or MDF sheet (for the manufacture of a speaker enclosure);
- marker;
- jigsaw;
- 400 W PC power supply;
- radio;
- Bulgarian;
- a pair of acoustic speakers;
- furniture screws and screws;
- sealant (best used on the basis of silicone);
- voltmeter and glue.
Before assembling the speaker system, first of all, check the operability of the radio and find out whether it can be powered or not. It is also necessary to test the speakers for sound quality. After that, you can safely proceed to the manufacture of the body and other elements of the speaker system.
Body manufacture
As the walls for the column, you can use a regular sheet of MDF or particleboard. At the same time, it is unacceptable to use plywood, because by its characteristics it is very flexible and emits a strong resonance. When making a case for the speaker system, also take into account the fact that the more air remains inside the box, the softer the bass will be. Therefore, leave as much free space as possible, but everything should be in moderation (otherwise such columns will simply be impossible to transport).
Place the shelf so that the maximum amount of air enters the speakers. Mark the places for cutting further with a marker. Now you can safely cut a sheet of chipboard with a jigsaw. We also note that the edges of the trimmed parts of the tree should be carefully aligned. To do this, use a small construction grinder. Please note that it can work with several discs - for metal and wood. We need the latter option, since when processing such materials, the cutting element of the first type is simply erased and even smokes. Experts recommend the use of a petal circle.
Now the matter is left to the small. On the case, mark the places for screwing furniture screws and with a screwdriver tighten them to the end. In the case of screws, pre-mark them and drill through holes. Everything, the case for the speaker system has been successfully manufactured.
Wall fasteners
The emphasis should be on the strength of the wall fasteners. Do not save on screws and screws. The housing design for the speakers should be as strong and strong as possible. If the number of screws is insufficient, under heavy load the walls of the system will rattle strongly, thereby only worsening the sound quality.
Thorough assembly
How do you make a three-way speaker system do it yourself next? After you have made the case (the so-called "monoblock"), you can begin to thoroughly assemble the structure. It is best to use a cordless screwdriver with a 4-mm hexagon to tighten the screws. Remember that inside the column its own sound load is distributed from minimum to maximum - the lower wall, upper, front and side.
How do you do the speaker system yourself? At the next stage, the joints should be treated with silicone sealant. This is necessary in order to prevent the penetration of excess sound waves from the body out through the slots. Thus, the level of music playback will become even better. How do you do the speaker system yourself? After lubricating all the cracks with sealant, you will need to install the speakers and radio. The latter is best purchased assembled. The speakers together with the radio are installed through the holes made in the bottom wall of the monoblock.
When everything is ready, the final form of the design should have the following appearance: on the back of the monoblock there is a power supply, on the sides there are two speakers (each of which is located in a separate column) and in the middle is a car radio. The manufacture of speaker systems with your own hands takes place in a certain sequence of actions - first the power supply is mounted, and then the radio tape recorder. So it will be much more convenient for you to fasten the fasteners. But at this stage, the speaker system for the TV and PC is still not completely assembled. Next, you will need to increase the stiffness of the corners. We will tell you about this in the next section.
How to make a speaker system with your own hands? Strengthening the stiffness of corners
The whole essence of the work lies in pasting certain parts of the monoblock with the subsequent installation of square or triangular glazing beads on them. It is not necessary to use “Moment” as an adhesive. The usual "PVA" will completely cope with this matter. Before applying glue to the surface of the material, make sure that it is in a dry state and that its surface is free of cracks and bends.
What needs to be done in order for the power supply to work?
To do this, you will need to put a jumper on a wide, large connector (in other words, close it). It is enough to use a regular paper clip. With it, connect two wires (green with black) and check the operability of the device with a voltmeter.
To make these elements more conductive, after making contact, carefully solder their connection points. Now put the block body inside the monoblock and attach it with self-tapping screws. Also treat all formed cracks with sealant.
About Soundproofing Material
At the next stage, the do-it-yourself speaker system is filled with special soundproof material (here you can use a regular synthetic winterizer). They need to fill the entire volume of the columns.
In this case, you can not apply it to the diaphragm. This soundproof material significantly reduces the load on the walls of the system and reduces the speed of sound waves. So, when playing a melody, the speaker design will practically not vibrate. However, do not follow the principle of "the more, the better." If you overfill the column with a syntepon, it can lose bass, and accordingly, the sound quality will significantly deteriorate.
Fan
If your speaker system for a TV or computer is designed for more playback power, think about additional cooling elements.
Indeed, at high load, the elements of the columns become very hot, which can cause their premature failure. And you need to install the fan in such a way that it blows from the inside out, that is, hot air leads out onto the street (or room). If heat is removed from the radio, overheating of system parts will be eliminated, and your speakers will last a very long time. At this stage, the question of how to make a three-way speaker system with your own hands can be considered closed.
