Audio Products

Audio products encompass components for sound generation, reproduction, and alerting — from miniature SMD buzzers to professional-grade speakers. This category includes speakers, microphones, buzzers, sirens, audio amplifiers, and piezo elements. Key parameters for speakers: rated power, impedance (4/8 ohm), frequency response, SPL (sound pressure level), and form factor. For MEMS microphones: sensitivity, SNR, frequency response, and digital interface (PDM/I²S). Piezo buzzers provide compact, low-power alert tones with simple drive circuits. Popular manufacturers: CUI Devices, PUI Audio, Knowles, TDK, Murata, and Mallory Sonalert.
