Peculiarities

Boombox is a small but powerful musical column that has a separate power supply. It requires the following.

  • 18 mm thick board.
  • Plywood 5 mm (External Front Panel).
  • Plywood 12 mm (rear panel).
  • Background pipe 42 mm.
  • Plexiglass.
  • Clamps (self-tapping screws, configmatics for furniture).
  • Car glue and glue Super cement.
  • Solder.
  • Paint in the cylinder.
  • Khomuta.
  • 12 volt battery, 7.3 A / h (it can be taken from the power supply of the laptop).

Recharge 1 A / h. Sound is reproduced from the Pioneer MV 194 UB car radio. Speakers have AV PB-64.2. Dimensions 152 x 192 x 642 mm. Weight 6.5 kg. You can take speakers for high frequencies – 17 cm, for low frequencies 22 cm. You should pay attention to the wiring coming from linear output. Put it better shielded wiring and remove the power supply. Permissible to think about increasing the volume of the tank itself (drawer). Some wizards are placed in the wool space or a bag that is packed with foam rubber, then the sound may change for the better.

Holes for speakers are cut with a mill, the brass can be up to 46 °.

It is important to calculate the sizes of the panels so that they match, there would be no distortion.

When the panels are glued to use, the clamps are recommended, the back cover is mounted at the end, after all the wiring is installed. Plywood body before painting is treated with universal bactericidal primer.

Necessary materials

To make a boombox from a car machine that served your time, it is recommended first to remove the speakers. This requires:

  • soldering iron;
  • screwdriver;
  • scissors.

Tools will be required:

  • drill;
  • Bulgarian;
  • screwdrivers (crusades simple);
  • scissors, knife;
  • nippers;
  • Passatia;
  • glue;
  • Self-tapping screws, bolts “3” mm.

The power of each speaker can be 5 watts each, have 4 ohm. The speakers are fixed in a new building that can be made from a cardboard box. It is permissible to make a container from an aluminum-wooden suitcase, in it once attended a set of Chinese modules. Some craftsmen make the hull from plywood. What is needed to make boombox from the old radio:

  • speakers from 2 to 6 pieces;
  • box;
  • amplifier;
  • Li-Pol Charger;
  • switch;
  • Indicator showing the level of charging.

    First, outlines for dot speakers. The drill “3” are made holes. Install the speakers using 3 mm bolts. We put Driver. Holes for fastening cut through the housing:

    • indicator;
    • switch buttons;
    • Volume controller;
    • Sound Jack, which serves an audio signal;
    • connector, it provides a lithium charging device.

    It is important to see all the details are tightly fixed, and there were no cracks in the housing. Especially carefully recommended to take the joints. For sealing unnecessary holes, it is good to use silicone, it reliably fixes and creates reliable tightness of the container.

    Now turn the e-filling. Install the button on the battery tester, it will light up during operation. Another resistor is mounted on the switch (1 com), then the backlight will be able to work, which will be clearly visible. From the board is soldered for jack connector, we switch the wires to Jack of the future boombox.

    The amplifier connects to 12 volt charger. The fan is soldered directly to the amplifier connector. The potentiometer can be further lengthened using a cable. All items are located in the container. Some elements can be fastened with a scotch tape or glue.

    Speakers collect from 4 to 6 pieces, each has 4 ohms. Connect all audio blocks to one two-channel amplifier. Option One: Disable speakers sequentially (minus first speakers connect with “+” second, after that minus the second with a plus of the third and T. NS). It turns out, in the end, the amount of 24 ohm is a lot, it is necessary to reduce the parameters.

    If you connect in a parallel, then the resistor will be extremely small, which does not always meet the required requirements. Therefore, it is necessary to combine elements. Total power will be about 30 watts. If there are two channels connected, the power will be increased. As you can see, If we collect homemade boombox from the car machine, then there should be no difficulties, it’s a simple piece of product.

    For homemade boombox you can make a housing with a thickness of 20 mm and to paint outside. The result may turn out very good. It is recommended to make drawings in advance to accurately calculate all sizes. Before the portable boombox earned, the surface should be seized, for this, sequentially sandpaper is used:

    • 122 grit;
    • 230 grit;
    • 410 Grit.

    Inserting joints is an important topic, there should be no extra slotes between the case and speakers. For these purposes, use the 3D printer and special software.

    Little rings are printed (4-6 pieces.) and fixed using a thermal. Day should be withstanding a pause so that the glue is fixed. For painting you should use glasses, respirator and gloves. Paint better in the technical room (garage, warehouse and t. NS.). Make, obviously, have several layers before “put” the second layer. Should wait when the previous ones dried. To dry out paint you want to wait at least 3 days.

    Upon closer review, it becomes obvious: to make a “branded” boom-box is technologically easy, all components are dismantled with old audio equipment. Materials to make the box, cost cheap.

    It is only important to calculate everything in advance and make the correct scheme of the device.
