PUI Audio 0.8 W Miniature Speaker 20 mm Dia. 2.8 mm, 20mm

This miniature speaker is a Compact acoustic transducer designed for integration into small electronic assemblies where space is limited. It converts electrical signals into sound with a mylar diaphragm, offering a balance of sensitivity and Compactness suitable for embedded audio indication and alarms in industrial and consumer electronics.

• 20kHz upper frequency delivers clear high-frequency response
• 90dB sensitivity achieves audible output from low drive levels
• 8Ω impedance ensures compatibility with common driver stages
• 0.8W rated power supports short-duration signalling duties
• REACH and RoHS conformity aids regulatory acceptance

• Suitable for audible alerts in automation control panels
• Ideal for feedback tones in handheld test instruments
• Used for status chimes in IoT sensor nodes
• Can be used for warning beeps in Compact mechanical assemblies
• Used with PCB mounting in miniature consumer electronics

The device has a square profile with 20mm sides, allowing for straightforward placement on standard small PCBs and simple mechanical securing methods.

The speaker's low-profile 4.5mm height permits installation in shallow housings and thin enclosures commonly found in portable electronics.

The diaphragm is manufactured from mylar, which contributes to stable, lightweight motion and predictable frequency behaviour across mid-to-high bands.

Operate the transducer within its 0.8W continuous rating and match to an 8Ω output stage to avoid thermal or mechanical stress.
