GA0729

Speakers Overview

The GA0729 is a general-purpose speaker manufactured by Same Sky (Formerly CUI Devices). It features an 8-ohm impedance and a rated power of 500 mW. The device operates within a frequency range of 400 Hz to 20 kHz, with a self-resonant frequency of approximately 400 Hz. It utilizes a top port configuration and has a rectangular shape. The speaker employs paper/cloth for the cone material and Nd-Fe-B for the magnet. Electrical efficiency is specified at 79 dBA when tested at 1W/1M.

Speakers Feature Summary

• Top port acoustic design for direct sound projection
• Rectangular form factor utilizing paper/cloth cone materials
• Neodymium iron boron magnetic structure for compact performance

Speakers Applications

• General purpose audio output devices
• Consumer electronics enclosures requiring top-firing speakers
• Compact audio modules in rectangular housings

Speakers Procurement Notes

Verify the specific datasheet version for the GA0729 to confirm exact sensitivity tolerances and mechanical mounting hole dimensions. Ensure that the 8-ohm impedance matches the amplifier output requirements of the target system. Check for RoHS compliance documentation if required by the end-product regulations. Confirm availability status as manufacturing schedules may vary.

Speakers Selection Notes

Select this component when a rectangular speaker with top-porting is required for space-constrained designs. The 8-ohm impedance suits standard low-power audio amplifiers. Consider the 400 Hz lower frequency limit; it is not suitable for applications requiring deep bass reproduction. The 500 mW rating defines the maximum continuous power handling capability.

Speakers Part Context

This part belongs to the general-purpose speaker category from Same Sky. It is distinct from other series like the CDS micro-speakers which often feature different impedance values and size profiles. The GA0729 represents a standard rectangular driver solution rather than a miniature or high-efficiency specialized variant.

Speakers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing mounting holes and electrical connections before considering alternative generic rectangular speakers.
