Upgrade your sound system with our Thin Speaker! Measuring just 28mm, this 4 Ohm, 2.5W speaker is sleek and powerful. Perfect for any DIY audio project.

Turn any surface/wall/table etc into a speaker with a surface transducer. This type of speaker does not have a moving cone like most speakers you've seen. Instead...

Surface transducers give you the awesome power to turn almost any surface into a speaker...

This basic piezo sensor from Measurement Specialties is often used for flex, touch, vibration and shock measurements. A small AC and large voltage (up to +/-90V) is created when the film moves back and forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch.

The vibration motor is very similar to the device that makes your cellphone shake when you get a text. With this module, you can make anything vibrate and buzz! This module also includes the vibeSnap-- an accessory that helps you attach stuff - like paper, tin foil, or a pipecleaner - to the motor.

This is a small buzzer for the LilyPad system. Use 2 I/O pins on the LilyPad main board and create different noises based on the different frequency of I/O toggling. Loud enough to hear inside a pocket but not obtrusively loud.

The Minisense 100 from Measurement Specialties is a low-cost cantilever-type vibration sensor loaded by a mass to offer high sensitivity at low frequencies. Useful for detecting vibration and ‘tap’ inputs from a user. A small AC and large voltage (up to +/-90V) is created when the film moves back an forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch.

Based on a new generation ARM Cortex M7, the Qwiic Tsunami extends polyphony to 32 mono or 18 stereo simultaneous uncompressed 44.1kHz, 16-bit tracks...

This thin silvery ribbon is an interesting sensor. It's made of 2mm wide by 600mm long piezoelectric film sandwich. Piezo film can be used to detect motion or vibration - when shifted around or touched, it creates a small current pulse across the terminals. If a 1 Mega-ohm resistor is placed across the two terminals you will see the current converted into a voltage that can be read by an analog-to-digital converter (ADC).

Knock on one Knock Knock box and the other box knocks too (try saying that three times fast). It’s like they’re a single object that somehow appears in...

The sound trigger listens to the noise level in your room, and sends an ON signal when it gets over a certain level. You can make that threshold louder or softer using the included screwdriver. We like to use it with an LED to light up your room when you snap your fingers.
