AS04004MO-SP40

Overview

The AS04004MO-SP40 is a general-purpose electromagnetic speaker from PUI Audio, designed for applications requiring extended flat high-frequency response. It features a rectangular shape with an oval cone and frame mount style. Key electrical parameters include a nominal impedance of 4 Ohms, a rated power of 2 W, and a maximum input power of 2.5 W. The self-resonant frequency is 400 Hz, with an operating range extending to 20 kHz. Sound pressure level is specified at 89 dB, while efficiency is rated at 75 ±3 dB.

Feature Summary

Designed for extended, flat high-frequency response suitable for mobile series applications
Utilizes a frame mount configuration with a rectangular shape and oval cone
Constructed with electromagnetic technology for general-purpose audio output

Applications

Mobile electronics requiring extended frequency response
General-purpose audio signal indication
Consumer electronic devices needing compact speakers

Procurement Notes

Verify the specific datasheet version for the AS04004MO-SP40 to confirm exact acoustic tolerances and mechanical dimensions. Ensure compatibility with panel mounting requirements due to its frame mount design. Cross-reference impedance and power ratings with your amplifier specifications to prevent damage. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement.

Selection Notes

Select this component when a rectangular speaker with a 400 Hz resonance is required for general-purpose use. It is suitable for designs prioritizing flat high-frequency response over deep bass reproduction. Consider the 4 Ohm impedance and 2 W rating for low-power driver circuits. The frame mount style simplifies integration into enclosures compared to board-mount alternatives.
