GF0778B

Speakers Overview

The GF0778B is a general-purpose audio speaker manufactured by Same Sky (Formerly CUI Devices). It features an 8-ohm impedance and a rated power of 3 watts, with a maximum power handling capacity of 5 watts. The device operates within a frequency range of 200 Hz to 15 kHz and has a self-resonant frequency of 250 Hz. It delivers a sound pressure level efficiency of 95 dBA. The speaker utilizes a top port configuration and includes a round shape with a square frame design.

Speakers Feature Summary

• High acoustic efficiency providing significant sound output relative to input power
• Robust power handling capabilities suitable for demanding audio applications
• Distinctive structural design combining a round diaphragm with a square mounting frame

Speakers Applications

• General purpose audio reproduction systems
• Portable electronic devices requiring high-output speakers
• Consumer electronics with limited enclosure space

Speakers Procurement Notes

Verify the specific mechanical dimensions and terminal configuration against the official datasheet before integration. Confirm that the operating temperature range meets the environmental requirements of the final assembly. Ensure compatibility with the intended amplifier output impedance to prevent damage or performance degradation during operation.

Speakers Selection Notes

Select this component when high sensitivity and power handling are prioritized over extended low-frequency response. The 95 dBA efficiency makes it suitable for battery-operated devices where maximizing volume per watt is critical. Consider the square frame geometry for mounting constraints in rectangular enclosures.

Speakers Part Context

This speaker belongs to the general-purpose audio product line from Same Sky. It is designed for applications requiring reliable acoustic performance in compact form factors. The manufacturer provides standard compliance certifications including RoHS, ensuring suitability for regulated markets.

Speakers Replacement Considerations

Direct substitutes must match the 8-ohm impedance, 3-watt rating, and 95 dBA efficiency. Verify that alternative components accommodate the same physical mounting footprint defined by the square frame design.
