The Great Search – 8 ohm 0.25W, 2″ diameter round speaker #TheGreatSearch @DigiKey @adafruit
This week (video), we have a request from someone working on a kit with an an audio output – they need to spec out an inexpensive speaker that will play the audio clips in their design and they had a few rough requirements they wanted to hit: the audio driving circuit they’re using is 8 ohms 0.25 Watt, so the speaker cant have have a lower power rating or it will blow out. The size is about 2 inches diameter, and it needs to be a round speaker to fit into the PCB. Finally, the audio frequency range is not that wide, we just need to play tones that are about 600 Hz.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
