Mini Speaker 8 Ohm 1W—Oval (8R 1W)🔊

This compact, diaphragm-protected mini speaker is engineered for reliable audio output in basic electronic circuits and embedded designs. Its oval 24 × 15 mm footprint makes it a versatile choice for space-constrained applications, from Arduino and Raspberry Pi projects to custom microcontroller-based modules.

✅ Key Features

• 8 Ω nominal impedance (8R) for broad compatibility with common audio amplifier modules.
• 1 W rated input power for clear output in compact designs.
• Oval 24 × 15 mm form factor for efficient use of PCB and enclosure space.
• Protective diaphragm helps guard the transducer against dust and handling.
• Ideal for alerts, tones, and simple audio in Arduino, Raspberry Pi, and other microcontroller projects.

⚙️ Technical Specifications

• Impedance: 8 Ω (8R)
• Rated Input Power: 1 W
• Dimensions (L × W): 24 mm × 15 mm
• Operating Temperature Range: −25 °C to +50 °C
