    What is this sensor? (Can detect the clap sound)

    This sensor can detect a shocking sound such as clapping by a amplifier.

    Thank you for your attention
    This is not a electered microphone because it needs to be biased،but my circuit does not have any powers and is like a piezo drive

    It looks quite similar to an ultrasonic piezo transducer. I doubt that it has much sensitivity in the audible sound range. Measuring the resonance frequency would be a first step to learn about its parameters.
