PUI Audio 8 Ω 3 W Miniature Speaker 25 mm, 41mm

This miniature speaker is a Compact audio transducer designed for integration into small electronic and embedded systems where space is limited. It delivers mid-to-high frequency sound reproduction suitable for signalling and voice prompts in industrial automation and control equipment. The unit is intended for applications requiring a low-profile audio source with a paper-cone diaphragm and standard 8Ω electrical loading.

• 3W rated power provides audible output for notification systems
• 86dBA sensitivity yields efficient sound level for alerting
• 20kHz frequency response supports clear high-frequency content
• 8Ω impedance matches common driver-stage outputs
• Paper cone delivers predictable tonal behaviour and low mass
• REACH and RoHS compliant materials aid regulatory adherence

• Suitable for audible alarms in automation cabinets
• Ideal for human to machine Interface voice prompts
• Used with control panels for status notifications
• Can be used for embedded devices requiring Compact audio
• Used for development boards and prototype electronics

The speaker expects an 8Ω load, drive circuitry should be matched to this impedance to avoid power transfer losses.

At rated input the sound level is 86dBA which is sufficient for signalling within small rooms or enclosed panels.

The diaphragm is MADE from a paper-based cone which influences transient response and midrange character compared with synthetic materials.

The module occupies a rectangular envelope measuring 41x71mm which should be accommodated when planning board or enclosure layouts.

Continuous operation should respect the 3W power rating to prevent thermal overstress of the voice Coil and surrounding assembly.
