AS01508AO-3-R

Overview

The AS01508AO-3-R is a general-purpose electromagnetic speaker manufactured by PUI Audio, Inc. It features an 8 Ohm impedance and a self-resonant frequency of 500 Hz. The device operates within a frequency range of 500 Hz to 14 kHz and delivers an efficiency of 94 dBA. Rated for 700 mW power handling, this top-port rectangular transducer is designed for compact audio applications requiring high sensitivity in a slim-line form factor.

Feature Summary

• High acoustic efficiency rated at 94 dBA for clear output
• Rectangular slim-line design optimized for space-constrained enclosures
• Top port configuration facilitates directed sound projection

Applications

• Portable consumer electronics with limited internal volume
• General purpose audio signaling devices
• Compact communication equipment requiring high sensitivity

Procurement Notes

Verify the specific suffix and package type against the official PUI Audio datasheet before ordering. Confirm that the rectangular footprint and top-port orientation match the mechanical constraints of the target assembly. Ensure the 8 Ohm impedance aligns with the driver circuit requirements to prevent mismatch issues.

Selection Notes

Select this component when high sensitivity (94 dBA) is critical for low-power operation. The rectangular shape distinguishes it from standard circular micro speakers, offering different mounting flexibility. Consider the 500 Hz to 14 kHz response curve to ensure suitability for voice or alert tones rather than full-range music reproduction.

Part Context

This model belongs to the PUI Audio slim-line micro speaker series, specifically engineered for thin-profile applications. The AO designation typically indicates the rectangular geometry and adhesive mounting style common in this product line. It serves as a specialized alternative to circular variants where board real estate dictates a non-circular footprint.

Replacement Considerations

Direct substitutes must match the 8 Ohm impedance, 94 dBA efficiency, and rectangular dimensions. Circular replacements like the AS01508MR-R will not fit mechanically without enclosure redesign. Verify that any alternative maintains the top-port orientation to preserve acoustic performance.
