MP-1103

Speakers Overview

The MP-1103 is a 4-inch (100 mm) ultra-lightweight piezoelectric wide-range speaker manufactured by MISCO. It features a 1 kOhm voice coil impedance and operates within a frequency range of 450 Hz to 20 kHz. The driver utilizes a phenolic-treated black cone capable of handling up to 50 Watts of power. Designed for durability, the piezoelectric construction resists burnout and performs reliably in demanding environments, including MRI rooms where magnetic interference is a concern.

Speakers Feature Summary

• Ultra-lightweight design suitable for wearable or portable applications
• Highly durable piezoelectric driver resistant to burnout
• Wide frequency response optimized for voice and alarm clarity

Speakers Applications

• Voice communication systems
• Alarm and alert signaling devices
• MRI room audio equipment
• Military-grade portable electronics

Speakers Procurement Notes

Verify that the specific order matches the MP-1103 designation for the 4-inch piezoelectric variant with 1 kOhm impedance. Confirm environmental ratings if deployment involves extreme conditions. Ensure interface compatibility with existing amplifier stages given the high impedance specification. Review datasheet specifications for power handling limits before integration into final assemblies.

Speakers Selection Notes

Select this component when weight reduction and acoustic durability are primary requirements. The high impedance allows for direct interfacing with certain signal sources without complex matching networks. Consider the wide-range capability for applications requiring both speech intelligibility and alert tones. Evaluate the non-magnetic properties if the installation site contains sensitive medical imaging equipment.

Speakers Part Context

This speaker belongs to MISCO's line of specialized electromechanical audio devices designed for rugged use. Unlike traditional dynamic speakers, the piezoelectric technology offers distinct advantages in shock resistance and thermal stability. The product series targets industries requiring reliable audio output in harsh or specialized environments where standard components might fail.

Speakers Replacement Considerations

Substitutes must match the 4-inch form factor and 1 kOhm impedance to maintain circuit compatibility. Verify that alternative piezoelectric drivers provide similar frequency response characteristics for voice reproduction. Check physical mounting dimensions to ensure fit within existing enclosures without modification.
