  Surface transducer - large
Surface transducers give you the awesome power to turn almost any surface into a speaker. They're 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. 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). * Impedance: 4ohms * Power: 3W * Dimensions: ø50mm x 31mm * Weight: 173g

  Surface Transducer - Liten
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

  Högtalare 4ohm 3W i låda med JST-kontakt
This 2.8" x 1.2" speaker is a great addition to any audio project where you need 4 ohm impedance and 3W or less of power. We particularly like this speaker as it is small and enclosed for good audio volume and quality. It has a handy JST 2PH input cable to add audio to your displays and other projects (this connector is part of the JST-PH series which is ~2.0mm spacing). Speaker weight: 26.4g Dimensions: 30mm x 70mm x 17mm / 1.2" x 2.8" x .7" Cable is 22.5" long 3.4mm diameter mounting holes 63mm x 24mm mounting rectangle
