PUI Audio 3 W Miniature Speaker 11.7 mm, 28.5mm

This miniature speaker provides Compact audio output for electronic systems, delivering audible continuous tones suitable for signalling and notification in industrial equipment. It is designed as a small loudspeaker component for integration into assemblies where space is limited and a consistent acoustic level is required.

• 4Ω impedance allows straightforward drive from low-voltage amplifiers
• 3W rated power supports clear output for short-duration alerts
• 82dBA sensitivity delivers high audible level for notification
• Paper cone construction offers predictable midrange response
• Continuous-tone operation enables steady-state signalling
• Frequency capability extends up to 20000Hz for broad-band reproduction

• Suitable for control panels requiring audible alerts
• Ideal for handheld instrumentation with limited space
• Used for factory automation status indication
• Can be used for electronic test rigs and prototypes
• Suitable for replacement in Compact audio modules

It presents a nominal 4Ω load, which should be matched to the amplifier's output capability to avoid excessive current draw.

It has a rated sensitivity of 82dBA, so in open conditions it produces a substantial level, enclosure acoustics and baffling will affect perceived volume.

The paper cone tends to produce a natural midrange presence suitable for tone signalling rather than highly coloured or bass-heavy reproduction.

Yes, it is specified for continuous-tone operation and rated for 3W, indicating suitability for prolonged alert tones within its power limits.
