AS04604PR

Overview

The AS04604PR is a general-purpose electromagnetic speaker manufactured by PUI Audio, Inc. It features a round shape with a 46 mm diameter and utilizes a paper cone material. The unit operates at an impedance of 4 Ohms and has a rated input power of 10 W. Its frequency response ranges from 220 Hz to 20 kHz, with a self-resonant frequency of 220 Hz. The device achieves a sound pressure level of 99 dBA and offers low total harmonic distortion, making it suitable for compact designs requiring robust low-frequency performance.

Feature Summary

• Designed for applications requiring robust low-frequency response
• Features low total harmonic distortion in compact designs
• Utilizes a paper cone and neodymium magnet structure

Applications

• General purpose audio output
• Compact electronic device integration
• Consumer electronics enclosures

Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer specifications may be updated. Confirm that the 4-ohm impedance and 10-watt power rating align with your amplifier or driver circuit capabilities. Ensure mechanical mounting dimensions are compatible with your enclosure design before finalizing procurement.

Selection Notes

Select this component when a balance of high efficiency (99 dBA) and wide frequency range (220 Hz to 20 kHz) is required in a small form factor. The 4-ohm impedance suits standard low-voltage audio drivers. Consider the paper cone construction for natural acoustic characteristics compared to synthetic alternatives.

Part Context

This model belongs to the PUI Audio general-purpose speaker series, which focuses on providing reliable audio transducers for various industries. The AS04604PR specifically targets applications needing higher power handling (10 W) than typical indicator speakers, bridging the gap between simple buzzers and full-range audio drivers.

Replacement Considerations

Direct substitutes must match the 4-ohm impedance, 10 W power rating, and 46 mm diameter. Verify that alternative models maintain similar sensitivity levels around 99 dBA to ensure consistent volume output without requiring amplifier adjustments.
