The Φ57x14H 100Ω 93dB Loudspeaker is a high-performance, compact electrodynamic speaker specifically designed for clear and near-constant audio reproduction. A wide variety of applications can utilize this speaker; space being the primary consideration in its use, the precise 57mm diameter and low profile (14mm high) make it the near perfect solution for electronic devices of smaller form factors. The 93 ohm voice coil and the previously mentioned high sensitivity ensure efficient operation, lower power being no obstacle to at least acceptable sound clarity.
Features：
Compact & Space-Saving Design: Measures 57mm in diameter with a near-slim 14mm mounting depth; easy integration into any form of compact electronic assembly is the primary consideration of this design.
High Impedance & Efficiency: A 100-ohm impedance being the main factor, along with the previously mentioned high sensitivity (93dB at 1W/1m), lends itself to near constant efficiency.
Clear & Balanced Audio: 57mm speaker engineered for clear mid-range frequencies and at least intelligible speech - alarm systems, simple intercoms and various voice prompt type applications being perfect examples.
Robust Construction: A durable paper or composite cone, some form of sturdy stamped frame and near perfect magnetic assembly all contribute to long term reliability; consistent (small to medium volume) performance is the end goal.
