Descripción

Upgrade Your Audio Projects with MELIFE 5W 8 Ohm Double Cavity Mini Speaker! Are you building a DIY Bluetooth speaker, designing a smart home device, or looking for a high-quality replacement speaker? The MELIFE 5W Full-Range Audio Driver is engineered to deliver exceptional sound quality in a compact form factor. Why Choose Our Double Cavity Speaker? The secret to its impressive sound lies in the Double Cavity (Dual-Chamber) Acoustic Design. By isolating the back wave of the speaker cone, this structure prevents sound cancellation and reduces unwanted resonance. The result? Deeper bass, clearer vocals, and a much wider soundstage compared to traditional single-cavity or open-back mini speakers. Technical Specifications: Power Rating: 5W (Max Power: 10W) Impedance: 8 Ohms Frequency Response: 150Hz - 20kHz Sensitivity: 85dB ± 3dB Magnet Type: High-density Ferrite/Neodymium Design: Double Cavity Acoustic Enclosure Pro-Tips for DIY Builders: 1. Amplifier Matching: For optimal performance, pair this 8-ohm speaker with an amplifier board that supports 8Ω output. 2. Sealing Matters: When mounting the speaker into your custom box, ensure the front baffle is properly sealed with EVA foam or glue to prevent air leaks, which can ruin the bass response. 3. Polarity: Always connect the red wire to the positive (+) terminal and the black wire to the negative (-) terminal to ensure correct phase alignment, especially when using two speakers for stereo sound.

Características

• DOUBLE CAVITY ACOUSTIC DESIGN: Unlike standard open-back drivers, this mini speaker features an advanced double-cavity acoustic structure. This innovative design effectively reduces internal resonance, minimizes sound distortion, and significantly enhances the low-frequency (bass) response, delivering a richer and fuller audio experience in a compact size.
• 5W POWER & 8 OHM IMPEDANCE: Rated at 5 Watts with an 8-Ohm impedance, this full-range audio driver strikes the perfect balance between volume and clarity. It is highly compatible with most mainstream mini amplifier boards on the market (such as PAM8403, TPA3116, TDA7492), making it an ideal choice for your custom audio builds without worrying about impedance mismatch.
• COMPACT YET POWERFUL SOUND: Measuring at a mini footprint, this small speaker unit is engineered to fit into tight spaces without sacrificing audio performance. The high-quality rubber composite cone and strong magnetic core ensure crisp highs, clear mids, and punchy bass, making it perfect for portable devices where space is at a premium.
• EASY WIRING: Comes pre-wired with JST-PH2.5mm-2 pin Interface for quick solder-free connections. Perfectly suited for DIY audio kits, Arduino/Raspberry Pi speaker projects, intercom systems, and replacing defective speakers in alarm clocks and sound modules.
• VERSATILE APPLICATIONS: This 5W 8-ohm replacement speaker is widely used for DIY Bluetooth speakers, smart home IoT devices, Raspberry Pi audio projects, portable radios, electronic toys, and repairing damaged sound systems. Unleash your creativity and build your own personalized high-fidelity audio equipment.
