GA0771M

Speakers Overview

The GA0771M is an electromagnetic speaker manufactured by Same Sky, formerly CUI Devices. It features a round shape with a top port configuration and utilizes a ferrite magnet paired with a polyethylene terephthalate (PET) cone. The unit has an impedance of 8 Ohms and a rated power of 1 W, with a maximum power handling of 2 W. Its self-resonant frequency is 280 Hz, and it operates within a frequency range of 280 Hz to 11 kHz. The sound pressure level is 90 dBA when tested at 1 W/500mm. Physical dimensions include a diameter of 77.00 mm and a maximum installation height of 24.00 mm. Termination is achieved via solder eyelets.

Speakers Feature Summary

• Top port design for directional acoustic output
• Electromagnetic transduction using ferrite magnet and PET cone
• Solder eyelet termination for circuit board integration

Speakers Applications

• General audio signal reproduction
• Electronic device alert systems
• Industrial control panel indicators

Speakers Procurement Notes

Verify the manufacturer designation as Same Sky, formerly CUI Devices, to ensure accurate sourcing. Confirm that the specific suffix M matches the required physical dimensions and terminal type. Check RoHS compliance documentation for regulatory adherence in target markets. Ensure the solder eyelet termination style aligns with the printed circuit board layout requirements.

Speakers Selection Notes

Select this component when a round form factor with top porting is required for acoustic directionality. The 8 Ohm impedance and 1 W rating suit low-power general audio applications. Verify that the 77 mm diameter and 24 mm depth fit within the available enclosure space. Consider the 280 Hz to 11 kHz frequency response for suitability in voice or alert scenarios rather than high-fidelity music reproduction.

Speakers Part Context

This model belongs to the GA series of speakers from Same Sky. It shares the electromagnetic technology and PET cone construction common to this product line. The top port variant distinguishes it from rear-ported models within the same dimensional family. It serves as a standard solution for general-purpose audio output in compact electronic assemblies.

Speakers Replacement Considerations

Cross-reference with other Same Sky GA series models sharing the 77 mm diameter and 8 Ohm impedance. Verify compatibility of the solder eyelet terminals with existing PCB footprints before substitution.
