20mm Round 8Ohm 1W Micro Audio Speaker Stereo Loudspeaker
This tiny 2cm diameter speaker produces 1 Watt of sound which is perfect for sound without losing space. It can be hooked up to most audio devices that support headphones. Great for having your robot talk/adding soundtracks to your electronics projects while conserving space.
The internal resistance/impedance of 8 ohms (most common for speakers) tells you what you need so you can determine the amount of current (Amps) your speaker will have running through it using Amps = volts/resistance where volts is the output voltage of your amplifier/audio producing device and resistance is the resistance of your speaker(s). This is useful for someone looking to hook up multiple speakers to one output.
