Bone Conductor Transducer - 8Ω 1W

A small 1W Bone Conductor. With this type of speaker, a surface can be turned into a speaker. It is also possible to place the speaker on the skin and hear the sound through the body.

Specifications:

Power: 1W RMS (2W max) Impedance: 8Ω Dimensions: 21.5 x 14.5mm See the following page for a tutorial with a similar speaker: [Bone Conduction Speaker] (https://www.instructables.com/Adafruit-Bone-Conduction-Speaker/)

Note: This products comes without wires.

Potentiometre

A potentiometer is a type of variable resistor with three terminals, one of which is connected to a cursor moving on a resistive track terminated by the other two terminals. This system makes it possible to collect, between the terminal connected to the cursor and one of the other two terminals, a voltage that depends on the position of the cursor and the voltage to which the resistance is subjected.
