This 23mm piezo transducer is able to generate a range of audible tones and frequencies when energised by a 12V peak square wave. Provided it is mounted rigidly in the prescribed manner, outputs of up to 80dB can be achieved.
Flying leads
Requires drive circuit
PCB mounting
Ideal for toys, clocks and watches, calculators and electronic games, using the transducer in place of a speaker
Suitable for use in professional, commercial and industrial applications.
Q. I'm looking to replace the uncased piezo transducer provided with the Genie Project Kit with one from which I can get more volume. Any suggestions?
A. Hi Graham. Thank you for your question. The sounder can be made louder by sticking it to a box or flat plastic sheet to act as a sounding board.The volume is mainly limited by the supply voltage to the genie which cannot exceed 5v.
If you add a 500R resistor or 1K in parallel with the piezo this will make it a bit louder. To get LOUD volume you would need to use an amplifier between the gene and a bigger speaker or larger Piezo.

A very good transducer as it has mounting holes which are extremely convenient for mounting onto projects and just generally securing into place. The transducer has a clear sound and is reasonably loud at 5v but could be used on 12v if the sounder needs to be louder as desired. The transducer was a good price and came very quickly.
