The MEIDI 2316 Active Piezoelectric Buzzer with Wire Leads is a piezoelectric active buzzer equipped with lead-wire terminations for installations where PCB mounting is not practical. The internal oscillator enables direct DC excitation across the 3–24 VDC range, producing output at 3000 ± 500 Hz without external waveform circuitry.
The attached lead wires allow flexible positioning relative to the driver circuit. The black ABS housing maintains dimensional stability across the -30 ℃ to +85 ℃ storage band.

The MEIDI 2316 Active Piezoelectric Buzzer is a piezoelectric active buzzer designed for DC-powered alert circuits. The internal oscillator removes the need for external waveform generation — applying voltage within the 3–24 VDC window initiates audible output at the 3000 ± 500 Hz resonant frequency.
The Φ23.0 × 16.0 mm footprint and through-hole termination suit PCB assemblies using wave or manual soldering. The black ABS enclosure provides structural integrity across the -20 ℃ to +80 ℃ operating band.

The MEIDI 23*10mm Piezoelectric Passive Buzzer is a piezoelectric passive buzzer with Φ23.0 × 9.8 mm dimensions and 3500 ± 500 Hz resonant frequency. It accepts external square-wave or PWM drive signals from 1 V to 30 V, enabling tone modulation through external drive signal variation. Manufactured with a piezoelectric actuator containing no magnetic coil, the black PBT housing and through-hole mounting support wave soldering and manual soldering processes — suitable for sourcing in audio alert and industrial control applications.

The MEIDI 17*8mm Piezoelectric Passive Buzzer family offers two resonant frequency options on a shared mechanical platform. Both variants share identical Φ17.0 × 8.0 mm dimensions and through-hole mounting, letting engineers pick frequency without PCB layout redesign — ideal for sourcing flexibility. The HNR-1708 features 3000 ± 500 Hz resonance, ≥85 dB SPL at 10 cm (12 Vp-p square wave), and 1 g weight. The HNR-1708 PA10 delivers 2000 ± 500 Hz resonance, ≥75 dB SPL at 10 cm, and 1.4 g. Both accept external square-wave drive for tone modulation. Manufactured with a coil-free piezoelectric actuator, black PBT housing, and through-hole mounting, they support wave and manual soldering processes.
