  1. Remember to credit/reference all your images to their authors. Open source helps us create change faster together, but we all deserve recognition for what we make, design, think, develop.

  2. remember to resize and optimize all your images. You will run out of space and the more data, the more servers, the more cooling systems and energy wasted :) make a choice at every image :)

This image is optimised in size with resolution 72 and passed through tinypng for final optimisation. Remove tips when you don't need them anymore!

Process and workflow

(https://www.instructables.com/Embroidered-Fabric-Speaker/)

Instructions to make a soft speaker:

1) To create a functional speaker using an embroidery machine, you will embroider a coil pattern with highly conductive thread, which acts as the speaker's voice coil, onto a suitable fabric.

Materials Needed 1) Embroidery machine 2) Highly conductive thread (copper or metallic threads work, but can be brittle) 3) Regular thread 4) Fabric: Choose a material with appropriate stiffness; too soft and it will absorb vibrations, too stiff and it won't be able to move. Digital embroidery design: A tight spiral or arithmetic spiral design is recommended. 5) Permanent magnet (a strong, rare-earth magnet works well) Audio amplifier and power source: A 20W class-D audio amplifier (like the MAX9744) and a 5V DC power adapter are an example of components used in a project. 6) Cables: For transmitting the audio signal.

Cables and connection points: Snaps or solder for connections.

Instructions 1) Digitize the Design: Create or obtain a digital embroidery file with a tight spiral or arithmetic spiral coil design. The coil's dimensions should align with the size of your permanent magnet to ensure the magnetic fields can effectively interact.

Machine Setup:

1) Place the conductive thread in the bobbin spool, as the thread is less likely to break or knot there due to friction. 2) Use regular thread for the top spool. 3) Upload the spiral design to the embroidery machine.

Embroidery Process:

1) Hoop and stabilize your chosen fabric. 2) Run the embroidery machine to stitch the coil pattern. 3) Connect the Electronics: Ensure the signal is transmitted effectively by using cables to connect the ends of the conductive thread coil to your amplifier circuit. Connection points can be made with snaps or by carefully soldering the wires. 4) Connect the amplifier to an audio source (like a phone or music player).

Assemble and Test:

1) Hold or fix a permanent magnet close to the embroidered coil on the fabric. 2) Run an amplified sound source through the coil. The interaction between the electric current in the coil and the magnetic field of the permanent magnet will cause the fabric to vibrate, producing sound. The stiffness of the fabric and the tightness of the coil will affect the speaker's volume and sound quality.

footnote fabrication files

Fabrication files are a necessary element for evaluation. You can add the fabrication files at the bottom of the page and simply link them as a footnote. This was your work stays organised and files will be all together at the bottom of the page. Footnotes are created using [ ^ 1 ] (without spaces, and referenced as you see at the last chapter of this page) You can reference the fabrication files to multiple places on your page as you see for footnote nr. 2 also present in the Gallery.

Code Example

Use the three backticks to separate code.

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}
