The 8Ohm 2W Cavity Speaker is a compact, high-efficiency micro speaker module engineered for applications requiring clear voice prompts, music playback, and audio feedback in tight spaces.
The 8Ohm 2W Cavity Speaker is a compact, high-efficiency micro speaker module engineered for applications requiring clear voice prompts, music playback, and audio feedback in tight spaces. Built with an integrated acoustic cavity enclosure, this module enhances sound resonance and volume while maintaining a ultra-small form factor (36mm × 18mm × 9mm).
Operating at a standard 8Ω nominal impedance with 2.0W rated power, the speaker delivers loud, low-distortion audio across a 300Hz - 10kHz frequency spectrum. Its sealed enclosure box directs sound efficiently, offering significantly superior acoustic clarity and punch compared to standard un-enclosed micro transducers.
This mini cavity speaker is widely used in IoT devices, smart home appliances, robotics, laptops, portable terminals, and wearable hardware. It interfaces effortlessly with Class-D audio amplifier modules (such as PAM8403, MAX98357A, or LM386) and popular development platforms like ESP32, Arduino, and Raspberry Pi.
