90 ohm Mini Speaker Electronic Stethoscope
The 90 ohm Mini Speaker by ISL is a precision acoustic transducer engineered specifically for the high-fidelity requirements of electronic stethoscopes and medical diagnostic tools. ISL value-added design ensures clear, accurate reproduction of low-frequency heart and lung sounds, providing clinicians with critical diagnostic clarity.
Component Benefits
Standard miniature speakers often lack the low-end frequency response and impedance matching required for medical auscultation. ISL provides a "Value-Added" acoustic solution that prioritizes the subtle nuances of diagnostic audio.
-
High Impedance Matching: The 90-ohm voice coil is specifically designed to interface efficiently with medical-grade amplifiers.
-
Enhanced Low-Frequency Response: Tuned to capture the deep frequencies of cardiovascular and pulmonary signals.
-
Ultra-Compact Footprint: Miniature diameter allows for seamless integration into ergonomic, handheld medical housings.
-
Durable Mylar Diaphragm: Resistant to moisture and humidity, ensuring consistent performance in clinical environments.
-
Value-Added Termination: ISL can provide custom lead wires and medical-grade connectors to simplify your device assembly.
