AS07104PO-R

Overview

The AS07104PO-R is an electromagnetic speaker manufactured by PUI Audio, designed for frame mounting applications. It features a rectangular shape with dimensions of 71 mm in length, 41 mm in width, and 25 mm in depth. The unit operates with a nominal impedance of 4 Ohms and has a power rating of 3 W. Its frequency response spans from 100 Hz to 20,000 Hz, with a self-resonant frequency of 250 Hz. The acoustic output reaches a sound pressure level of 86 dBA. Construction utilizes Neodymium Iron Boron (NdFeB) magnets and paper cones. Electrical connections are made via solder lugs, and the component functions within a temperature range of -20°C to +60°C.

Feature Summary

• Utilizes neodymium iron boron magnetic material for efficient electromagnetic transduction
• Features a paper cone diaphragm for audio reproduction
• Designed for secure frame mounting installation style
• Equipped with solder lug terminals for direct electrical connection

Applications

• Audio signal output in electronic devices requiring frame-mounted speakers
• Intercom systems utilizing electromagnetic transducers
• Public address components in commercial equipment
• Alarm or notification devices needing high sound pressure levels

Procurement Notes

Verify the specific suffix 'R' against the manufacturer's current datasheet to confirm packaging and compliance status. Ensure the 4-ohm impedance matches the amplifier output requirements. Confirm that the 71x41mm physical dimensions fit the designated chassis opening. Check RoHS documentation for regulatory compliance in target markets. Validate solder lug compatibility with existing wiring harnesses.

Selection Notes

Select this model when a rectangular form factor is required for space-constrained enclosures. The 3-watt power handling suits moderate volume applications. The 4-ohm impedance is standard for many consumer audio circuits. Consider the 86 dBA sensitivity for efficiency relative to available drive voltage. The paper cone offers a specific tonal characteristic compared to synthetic materials.

Part Context

This component belongs to the AS series of speakers from PUI Audio, which focuses on electromagnetic transducers for various audio applications. The series includes round and rectangular variants with different impedances and power ratings. The AS07104PO-R specifically addresses needs for higher power handling in a rectangular footprint compared to smaller round counterparts.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify mechanical mounting hole patterns and terminal orientation when considering alternative rectangular speakers from other manufacturers.
