PUI Audio 8 Ω 4 W Miniature Speaker 61.5 mm Dia. 29 mm, 66.3mm

This miniature speaker is a Compact audio driver designed for integration into electronic and automation systems where space and acoustic performance are important. It employs a paper-cone diaphragm and is suitable for applications requiring a focused high-frequency response up to 12 kHz. The unit conforms to current EU environmental directives for material restrictions and is intended for use in assemblies that demand a small, efficient transducer.

• 95 dBA sensitivity for clear output at lower input levels
• 4 W rated power supporting moderate playback volumes
• 8 Ω impedance enabling compatibility with common amplifiers
• Paper cone for consistent mid-to-high frequency character
• Low-profile 29mm height for confined installation spaces

• Suitable for industrial control panels requiring audible alerts
• Ideal for handheld diagnostic tools and portable instruments
• Used for bespoke audio feedback in automation equipment
• Can be used for notification sounds in electrical enclosures
• Used with Compact electronic projects requiring a small driver

The unit spans 61.5mm in diameter with a total length of 66.3 mm, so board layouts should accommodate this envelope Plus fixing clearances.

At 4 W input the driver delivers its specified acoustic output while operating into an 8 Ω load, providing predictable SPL for system calibration.

The construction meets RoHS 2011 and REACH requirements, indicating restricted hazardous substances have been managed in component selection.

The driver is optimised to reproduce content up to approximately 12 kHz, making it suitable for alerts and high-frequency signals common in control applications.
