ASX04004-R

Overview

The ASX04004-R is a round electromagnetic exciter speaker manufactured by PUI Audio, Inc. It features a 4-ohm impedance and a 3-watt power rating. The device operates with a typical resonant frequency of 450 Hz and delivers an 86 dBA sound pressure level. Constructed with a Neodymium Iron Boron magnet and a paper cone, it utilizes a top-port design for acoustic output. Physical dimensions are approximately 40 mm in diameter with a height of 12.5 mm. It employs solder eyelet termination and is designed for adhesive mounting.

Feature Summary

• Top-port acoustic design for direct surface vibration transmission
• High-strength neodymium iron boron magnetic circuit
• Paper cone construction for balanced audio response
• Adhesive mount installation style for secure attachment

Applications

• Surface-mounted audio excitation systems
• Industrial control panel indicators
• Consumer electronics haptic feedback modules

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status and exact dimensional tolerances before finalizing integration. Ensure the mounting surface is compatible with the adhesive requirements for reliable mechanical coupling. Cross-reference the impedance and power ratings with the driving circuit capabilities to prevent thermal overload or signal distortion during operation.

Selection Notes

Select this component when a compact, high-output exciter is required for rigid surfaces. The 4-ohm impedance suits standard low-voltage driver circuits. Consider the 450 Hz resonance for mid-range frequency emphasis. The adhesive mounting simplifies assembly compared to frame-mount alternatives. Evaluate the 12.5 mm depth constraint against available enclosure space.
