Though being limited by the dimension, the SPL of a magnetic buzzer can only reach to 90 dB.
To compare the two types of buzzers, the magnetic type can have lower frequency response with the same dimension. On the other hand, a magnetic buzzer can be driven to generate 85 dB by only 1.5V, but the consumption of the current will be much higher than Piezo one. 5V 75dB 4000Hz Miniature Smd Buzzer Lateral Sound SMT Buzzer: SM12PT03AV3SH: 12.0 12.0 3.
We suggest inputting higher voltage for a piezo buzzer, normally over 9V to have enough SPL. SMD Buzzer, find quality smd piezo buzzer,SMD active buzzer Manufacturers, buzzer piezo smd Suppliers and Exporters at Changzhou Manorshi Electronics Co.Ltd. Miniature Piezo Buzzer, PCB Mount, 85dB Guide for Installation with an ENVIROMUX Enterprise Environment Monitoring System E-BEEP2-x is a general purpose piezo buzzer to provide audible indication of alert when configured to respond to variations in a sensor’s readings. Piezoelectricity is an effect where certain crystals will change. The piezo buzzer is driven by square waves, and the magnetic buzzer needs 1/2 square waves to drive. A piezo buzzer is basically a tiny speaker that you can connect directly to an Arduino.

Miniature Piezo Buzzer, PCB Mount, 95dB Guide for Installation with an ENVIROMUX Enterprise Environment Monitoring System E-BEEP2-x is a general purpose piezo buzzer to provide audible indication of alert when configured to respond to variations in a sensor’s readings. Light weight, simple construction and low price make it usable in various applications like car/truck reversing indicator, computers, call bells etc. Buzzer/Speaker Aluminium Heat Sink Bread Board and Zero PCB PCT and DC Power. NTI e-beep2-800 Miniature Piezo Buzzer, 95 dB, 800 ft Description. Piezo buzzer is an electronic device commonly used to produce sound. Available in compact packages ranging from 3.2 mm x 3.2 mm to 9 mm x 9 mm, CUI Devices' surface mount micro buzzers feature sound pressure levels ranging from 65 dB up to 100 dB and feature profiles as low as 1.9 mm.

It gets the job done though.Passive type 9V piezoelectric buzzer Φ30*5mm without oscillator circuit CUI Devices' 3.2 mm to 9 mm, SMT micro buzzers target portable equipment applications. It's not super precise, and you may need to adjust DELAY_OFFSET to fine-tune the pitch depending on your processor's speed. Here's a quick Arduino sketch to have this component make an arbitrary tone by hooking it up to a digital I/O pin.
