Speaker 3W 4 Ohm Loudspeaker

Features

• Designed for Mini Power Amplifiers: Specifically suited for compact amplifier circuits and small audio systems requiring a 4Ω speaker load.
• 3W Rated Power: Supports a rated power of 3W, making it suitable for low-power audio amplification applications.
• 4Ω Impedance: The 4Ω rated impedance is suitable for many compact audio amplifier modules and mini amplifier circuits.
• Clear Sound Output: Designed to provide clear and audible sound for general listening and embedded audio applications.
• Moving Coil Construction: Uses a moving coil speaker design for converting electrical audio signals into mechanical movement and sound.
• Permanent Magnet: Equipped with a permanent magnet designed to maintain its magnetic properties during normal operation.
• Rugged Metal Outer Case: The metal housing provides mechanical protection for the speaker structure and helps make the unit suitable for installation in compact electronic equipment.
• Compact Design: With a maximum diameter of 4 cm and a thickness of 2 cm, the speaker can be installed where available space is limited.
• Easy Installation: The compact speaker format makes it suitable for integration into DIY projects, electronic enclosures, and small audio devices.
• Suitable for Electronics Projects: Can be used in Arduino projects, microcontroller-based devices, audio modules, alarms, portable electronics, and other embedded applications where the specified electrical characteristics are suitable.
• Wide-Area Sound Directivity: Specified with all-direction directivity, allowing the speaker to provide sound output without requiring a specific directional orientation.
• 100 dB/W Sensitivity: The specified sensitivity rating indicates the speaker's sound output level relative to an applied input power of 1W.
