Sensitive Audio Detector | AC Circuits | Electronics Textbook Detectors are intended to be used for balancing bridge measurement circuits, potentiometric (null balance) voltmeter circuits, and detect extremely low amplitude AC (“alternating current”) signals in the audio frequency range. It is a valuable piece of test equipment, especially for the low budget experimenter without an oscilloscope. Audio Detector Circuit seattlerobotics.org Audio Detector Circuit [Editors note: I grabbed this off our list server. This was too good to pass up. The Trinity Firefighting Contest uses a small piezo speaker to generate a tone that emulates a fire alarm. Circuit: Audio Signal Detector Switch__ Circuit designed ... Audio Signal Detector Switch This circuit will activate a transistor switch when it detects at least 50mv peak to peak of an audio signal. It could be used to turn on a relay, routing the signal to were it is needed. More Switch Circuits Sine Systems, Inc. | DIY Audio Detection Circuit The schematic for a very simple audio detector is shown below. Any audio level of 6 dBv or greater will maintain at least 0.5 volts DC at the output. This covers most "line level" audio sources. If greater audio sensitivity is needed, use germanium diodes (1N34) or Schottky diodes (1N5819) for D1 and D2. Circuit Audio Signal Detector SwitchHobby Corner Audio Signal Detector Switch Circuit designed by David A. Johnson, P.E. For some audio systems it is desirable to have an automatic switch circuit turn on other devices, such as an Amplifier, if an audio signal is detected on one line. Radio Circuits | Practical Analog Semiconductor Circuits ... The circuit in Figure below adds an audio amplifier to the crystal detector for greater headphone volume. The original circuit used a germanium diode and transistor. [DLS] A schottky diode may be substituted for the germanium diode. A silicon transistor may be used if the base bias resistor is changed according to the table.
