5W 8ohms 40x40mm Full Range Small Speaker

This compact 40x40mm full-range speaker delivers 5W of clear audio from an 8-ohm impedance. Designed for embedded installation in space-constrained devices, it features a small footprint (40x40x22mm) and 2-pin connector for easy integration. Built for durability, it offers dustproof, shockproof, and heat-resistant properties – ideal for remote controls, industrial equipment, model applications, and small to medium-sized devices.

Compact Footprint, Flexible Installation

• The speaker measures just 40mm wide, 40mm deep, and 22mm thick – small enough to fit inside:
• Remote control devices – embedded inside the housing
• Handheld terminals – barcode scanners, data loggers
• Industrial control panels – audible alerts and status announcements
• Robotics – sound effects or voice feedback
• Portable instruments – multimeters, test equipment with audio output
• DIY electronics projects – Arduino or Raspberry Pi sound
• 5W Power – The Sweet Spot for Small to Medium Devices

At 5 watts, this speaker offers the ideal balance:

• Loud enough for clear audibility in normal environments
• Not overpowered – won't blow out small amplifiers
• Battery-friendly – moderate power draw extends runtime
• Versatile – works with many off-the-shelf audio amplifier modules (PAM8403, LM386, etc.)
• 8 Ohm Impedance – Industry Standard

The 8-ohm impedance is the most common rating for small speakers, ensuring compatibility with:

• Most consumer and industrial audio amplifiers
• Embedded audio driver circuits
• DIY audio modules (DFPlayer Mini, MP3 playback boards)
• Alarm and notification systems

Dustproof shockproof speaker Application:

1. Consumer Electronics: Remote controls, smart home sensors, handheld games
2. Industrial: Control panels, alarm systems, equipment status annunciators
3. Robotics: Sound effects, voice feedback, error alerts
4. Medical Devices: Audible alarms, patient alerts, user prompts
5. Automotive: Dashboard alerts, aftermarket systems

Integration Tips:

• Amplifier matching: Use an amplifier rated for 8-ohm loads. Many small amp modules (PAM8403, LM4863) work well.
• Enclosure mounting: For best bass response, mount the speaker with a sealed rear chamber or at least some back volume.
• Wiring: The 2-pin connector simplifies assembly. Observe polarity for correct phase (though not critical for basic alerts).
• Volume setting: At 5W, this speaker can be loud. Test at lower volumes first to avoid distortion or discomfort.
• Protection: Even though it's dustproof, avoid direct exposure to liquids or extreme particulate.
