SCS Series

Introduced as the first model of Sonitron's piezoceramic speakers, the SCS-series are still being used for numerous applications. Good sound quality and limited distortion guarantee a clear reproduction of multiple tones. The piezo speaker has 60 % more net sound output per membrane surface than the electro-dynamic speaker in the function of the average current drain and average sound pressure level. ------------------------------------------------------------- SCS-17 ------- SCS-24 ------- SCS-32

Advantages: 

  • Very flat and solid construction
  • Dust, water- and shockproof front panel
  • Resistant to temperature variations
  • Broad frequency range in small sizes
  • Combined use as speaker/microphone
  • No electromagnetic field (EMC)
  • Little energy required at low frequencies
  • Less current consumption needed in the leads to the speaker
  • 60% higher acoustic output in smaller speakers compared to electrodynamic speakers
  • Low weight
  • High impedance
  • Can be driven directly by IC
