2.2 Inch 8 Ohm Mini Speaker 0.5W Round Metal Shell Compact Speaker for DIY and Home Theater

Magnet Speaker Compact external magnetic round speaker designed for lowpower audio applications. Offers a practical balance of size, materials, and electrical specifications for repairs, prototypes, and small devices. Key benefits Compact form factor saves space and fits into small enclosures while delivering usable audio for notifications and voice playback. Lowpower design matches small amplifiers and audio modules, reducing power requirements in portable or battery powered projects. Robust construction with metal and plastic components provides dependable mounting and longevity for repeated use. Technical highlights Power: 0.5 W suitable for lowpower audio tasks Resistance: 8 Ohm nominal impedance for standard smallspeaker loads Type: External magnetic, round design Magnet diameter: 31 mm / 1.2 in Overall diameter: 57 mm / 2.2 in Height: 16 mm / 0.63 in Materials: Metal and plastic construction Color: Silver tone and black How it solves common problems Replaces worn or damaged small speakers in portable electronics without needing significant enclosure modification thanks to its compact diameter and low profile. Works with lowpower amplifiers and audio output stages to deliver clear notification and voice audio without large power draws. Durable metals in the frame allow secure mounting, reducing rattles and movement in installed applications. Compatibility and installation notes Designed for use with lowpower amplifier boards, audio modules, microcontroller audio outputs with suitable amplification, intercom and doorbell systems, and portable radio or handheld device repairs. Nominal 8 Ohm impedance requires a matching driver or amplifier; do not exceed the 0.5 W power rating to avoid damage. Typical twowire connection; observe polarity when connecting. Secure mounting can be achieved with screws or adhesive depending on the enclosure. Use scenarios Replacement speaker for a portable radio or handheld communication device where space is limited and power is modest. Audio output for a DIY Bluetooth or microcontroller speaker project that needs a compact, lowprofile driver. Doorphone or intercom system speaker for clear voice notifications in a small housing. Why choose this speaker Precise physical dimensions and a low profile make it easy to integrate into existing enclosures. Standard 8 Ohm impedance and low power rating simplify pairing with common small amplifiers and audio modules. Metal and plastic materials offer a practical balance of durability and lightweight construction.
