  Surface Transducer - Small
Surface transducers give you the awesome power to turn almost any surface into a speaker. Much like our larger surface transducer, this is essentially just a speaker except instead of a cone, the coil is attached to a pad that conducts the vibration into whatever you press it against. You can hook it up to an audio source and press it against the nearest table, wall or cardboard box. You can even put it against your head and play music directly into your skull (the ultimate surround sound). * Dimensions: 21.5 x 14.5 x 7.9mm * Impedance: 8ohm ±5% * Resonant Frequency: 16kHz ±0.5 * Max Operating Voltage: 12Vpp * Frequency Response: 300 - 19000Hz * Rated input: 1.0 W * Operating Temperature: -20 to +60°C
  Speaker 8ohm ø30mm 0.2W PCB
This through-hole speaker is great for projects where you need something that sounds better than a piezo buzzer but don't have room for a full-blown speaker. This 30mm diameter speaker is encased in plastic and will handle about 100mW of power. Features: * Impedance: 8ohm * Power: 0.1W (0.2W max) * Diameter: 30mm * Height: 12.7mm * Pitch: 15mm
  Piezo element ø20mm 7BB-20-6
Piezo element that can be used either to play sound or in reverse, to pick up sound / vibrations Extremly low build height. Requires external oscillator. When used to pick up sound, it's usually called a contact microphone. Resonant frequency: 6.3 kHz ± 600 Hz Impedance: 350 ohm @ 6.3 kHz Diameter: 20mm Thickness: 0.42mm
  Geophone - SM-24
Need to put your finger on the pulse of the Earth? Did I just blow your mind? A geophone works by translating ground movement into voltage, which can easily be read by a microcontroller. The SM-24 geophone element is designed to offer the highest performance in seismic exploration based upon field-proven I/O Sensor technology. Low distortion, combined with excellent specifications, provide high-fidelity data. Basically, it's a super low frequency microphone for the ground. Perfect for all of your 2-D & 3-D seismic exploration needs with bandwidth from 10 Hz up to 240 Hz Tight specification, low-distortion geophone Extended spurious over 240 Hz, allowing full bandwidth at 2-ms sampling Sensitivity of 28.8 V/m/s
  Electret microphone ø4.4mm with wires
Miniature microphone of electret type. The microphone requires active drive. * Bias voltage: 2V * Impedance: 2kohm * Dimensions: ø4.4 x 2mm * Wire length: 67mm * Weight: 0.17g
  Miniature speaker ø30mm 8ohm 5W
Small speaker for computers and televisions. * Max power: 5W * Impedance: 8ohm * Frequency range: 150Hz - 20kHz * SPL: 78dB * Dimensions: 32 x 13mm * Model: BF32
