A piezoelectric speaker (also known as a piezo bender due to its mode of operation, and sometimes colloquially called a "piezo", buzzer, crystal loudspeaker or beep speaker) is a loudspeaker that uses ...

We'd like to drive a special piezo speaker, with 20Vp-p 50KHZ sinusoid that comes from a DDS. The approximate power needed at 50KHZ is 600mW (75Ohm). TPA2100 looks like a good solution but our ...

It runs on mains power and uses a 100dB piezo buzzer for ear-splitting effectiveness to alert [Adam] whenever the freezer is at 32°F/0°C or above. If the Arduino loses sight of the DHT22 ...

Our company manufactures a comprehensive line of audio indicators and transducers in piezo and electro-mechanical varieties, including microphones, speakers, and ...

Raspberry Pi (any model, but Pi 3 or 4 recommended) Piezoelectric Speaker (also called a piezo buzzer) Jumper Wires (for connecting the piezo to the GPIO pins) Breadboard (optional, but helpful for ...

This repository contains the firmware source code and the hardware design files. The documentation generator configs can be found at https://github.com/Tinkerforge ...

YouTuber [MechnicalRedPanda] has recreated a DIY STM hack we covered about ten years ago, updating it to be primarily 3D-printed, using modern electronics, making it much more accessible to many ...

I would also to add a sound indicator, connecting one piezo speaker directly between a GPIO and GND of the microcontroller and controlling it with output GPIO. Like most electrical components, there ...

Apple's iPod nano, according to reports, will undergo a major design overhaul later this year. If a post on Macotakara is anything to go by, the design overhaul... Looks like folks at Apple ...
