3 Tone Gong Schematic
3 Tone Gong
3-tone-gong
This 3-tone-gong is designed to signal different driving directions in different wave forms.
This is done with a SAE800 IC.
There is a 8 pin header that is used to activate a single,
twice or three tone gong melody with active high or active low signals.
Two potis are used for volume control and pitch control.
The 3-tone-gong comes with a 8 ohm / 2W speaker.
input voltage: 12VDC - 30VDC.
power consumption: 2W
input voltage: 12VDC - 30VDC.

110 dB Beeper
110 dB Beeper
The setup employs a single 74C14 (CD40106B) CMOS hex inverting Schmitt-trigger IC, which must be used with a piezoelectric device with a feedback terminal. The feedback terminal is attached to a central region on the piezoelectric wafer. When the beeper is driven at resonance, the feedback signal peaks.
