The TR-WS-2014B Ultra-Thin Cavity Speaker (also known as HC2014B) is a compact, high-efficiency micro speaker module engineered for applications requiring reliable voice broadcast and audio output… -20°C to +75°C.
The TR-WS-2014B Ultra-Thin Cavity Speaker (also known as HC2014B) is a compact, high-efficiency micro speaker module engineered for applications requiring reliable voice broadcast and audio output in extremely tight spaces. Featuring an integrated acoustic cavity enclosure with side-emitting sound output, this miniature speaker maximizes volume and acoustic clarity while maintaining a low-profile thickness of just 4.5mm.
Operating at a standard 8Ω nominal impedance with 1.0W rated input power (1.5W max power), the speaker provides strong mid and high-frequency sound reproduction across a wide frequency range (F_0 - 20kHz). Its enclosed cavity design delivers significantly better resonance, lower distortion, and enhanced audio projection compared to raw, un-enclosed micro speaker transducers.
This ultra-thin cavity speaker is widely used in facial recognition terminals, smart home voice prompt systems, handheld game consoles, laptops, tablets, and IoT telemetry devices. It easily interfaces with Class-D audio amplifier modules (such as PAM8403, MAX98357A, or LM386) and microcontrollers like Arduino, ESP32, and Raspberry Pi.
