Attaching it to something metal like a washing machine or disposable aluminium roasting tin creates a peculiarly metallic effect. Smallest piezoelectric sounder in the world with 65 dB sound pressure output from Murata Murata now is offering the smallest and lightest surface-mount piezoelectric sounder available. You need to glue or firmly attach it to a large cardboard box or something similar. Using the largest size as a speaker can be achieved by driving it backwards from a standard radio output through an LT700 audio matching transformer available on another listing. The output can go directly into a standard low level microphone input socket on a tape recorder or computer sound card using screened cable. Two can be used at different spots on the wire for a stereo effect. The piezo part of the bare element will crack and degrade if bent, so the usual method is to attach the element to a piece of tin can first before attaching that to the vibration source. For example a 10 metre long stretched copper wire when plucked produces something very similar to the old star trek "phasers striking hull," noise, that being a similar method to how they created it in the first instance. I've also used these as contact microphones attached to machinery, farm fences in windy conditions or long stretched wires which can result in some very interesting sound effects.

BUZZ, 1-1/2 to 12 VOLTS DC HIGH PITCH PIEZO BUZZER-LOUDNESS 60 dB to 70d dB. When a current is run through this element, it vibrates in accordance with the frequency of the current. The 20mm unit is approximately 0.4mm thick with the 27 and 35mm units being about 0.5mm, excluding the solder connections and wires. SP230B, 120 VOLTS AC WALL MOUNT OR TABLE TOP PROGRAMMABLE WIRELESS ALARM. What types of electronic sounder are available Several varieties of audible alarm are on offer in the RS range: Piezo sounders - Piezoelectric sounders feature a piezoelectric element produced from a crystalline or ceramic material. They have wires attached and are often used in equipment where there is a need for a simple beep sounder, often driven direct from a logic output. This is one item of new piezoelectric speaker element available in a pack quantity of 1, 5, or 10 items.
