PUI Audio 3 W Miniature Speaker 28 mm Dia. 16.5 mm, 32mm

This miniature speaker is a Compact audio transducer intended for use in electronic and electromechanical systems that require lightweight sound output. It converts electrical signals into audible sound and is suitable for integration within portable and embedded devices where space is restricted and a clear high-frequency response is needed.

• 20000Hz frequency supports extended high-frequency reproduction
• 3W rated power delivers measurable acoustic output for alerts
• 85dBA sensitivity produces audible tones at low drive levels
• 8Ω impedance ensures compatibility with standard driver circuits
• Mylar cone provides stable diaphragm performance across use cases

• Suitable for integration into portable devices requiring audio alerts
• Ideal for audible signalling in automation control panels
• Used with Compact enclosures in handheld instrumentation
• Can be used for prototype audio modules on PCB assemblies

The speaker’s Compact footprint permits flush or surface mounting on PCBs or small brackets, ensure the enclosure allows a clear acoustic path for the intended output.

The Mylar cone offers dimensional stability and predictable transient response, benefiting applications where consistent high-frequency reproduction is required.

It operates with an 8Ω nominal load and is appropriate for low-power amplifier stages that can deliver up to the 3W rated power without exceeding thermal limits.

It is specified to reproduce frequencies up to 20000Hz, making it suitable for signalling and tones that rely on high-frequency content without low-frequency emphasis.
