user71093: Can normal buzzer be used for generating high frequency audio and if this is possible then can normal microphone module be able to detect the same frequency range(15 kHz - 20 kHz).
Here is the specifications of this buzzer:-
Rated Voltage : 6V DC
Operating Voltage : 4 to 8V DC
Rated Current* : ≤30mA
Sound Output at 10cm* : ≥85dB
Resonant Frequency : 2300 ±300Hz
Tone : Continuous
Operating Temperature : -25°C to +80°C
Storage Temperature : -30°C to +85°C
Weight : 2g
*Value applying at rated voltage (DC)



user32752: An arduino is very well capable of producing a 20KHz signal. You can use a PWM signal on one of the PWM pins, generate the signal by alternating a pin high and low with a few microseconds in between or you can use a buzzer with an input signal that can play a continuous tone at a specified frequency. I really can't see if the module you show can generate a tone based on the input.
Detecting a tone, however is somewhat difficult. You need an analog microphone amplifier, an ADC (analog-to-digital-converter) and some processing to detect a frequency in the signal data.
The usual microphone modules that are sold for arduino's are mostly just noise detectors and generate a signal when loud noise is present.
