Miniature Piezo Transducer with Flying Leads

<p>This 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.</p>

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.
Durable in domestic appliances
Available in 12.5, 23 and 30mm diameter options

Note: Not suitable for speech and music.

24 January 2013 Question by: Graham | Product code: 35-0046

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.
