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.

Featuring two acoustic output tiers in one shared form factor, the MEIDI 14*4mm Piezoelectric Passive Buzzer series streamlines procurement for design teams. Both variants measure Φ13.8 × 4.0 mm and resonate at 4000 Hz, so engineers can swap sound pressure levels without reworking PCB layouts or drive circuitry. The standard HNR-1404 produces ≥70 dB while drawing ≤5 mA; the high-output HNR-1404 PA7.5 reaches ≥80 dB at ≤10 mA. Each runs on external square-wave or PWM signals spanning 1 V to 30 V, supporting adjustable tones through drive parameter changes. Supplied with a coil-free piezoelectric build — well-suited for magnetically sensitive environments — these buzzers come in black PBT housings with through-hole pins and are compatible with manual soldering.

The 1207 Piezoelectric Passive Buzzer with Pogo Pin is a through-hole piezoelectric passive buzzer. As a passive unit, it relies on an external AC drive — typically a square wave or PWM around its 4000 ± 500 Hz resonance — to produce audible output. Its drive signal spans 1–30 V peak-to-peak, giving circuit designers wide voltage flexibility without tight regulation. The 5 V rated voltage serves as the test reference. Measuring Φ12.5 × 7.0 mm and weighing 0.66 g, the black PBT housing suits both wave and manual soldering profiles. Its coil-free piezoelectric architecture sets it apart from electromagnetic buzzers, with no magnetic coil or moving armature inside — well-suited for sourcing into magnetically sensitive assemblies.
