Mosquito Ring tones or High-Pitched Repellent that only teens can hear and adult ignore

This idea is really thinking outside the box. Innovation that lots of company can't even think of. I try many times thinking of Invention Disclosure Filing but this have never crossed my mind.
This is using different frequency that human can hear. For example, dogs can hear much higher frequency than human. This is using the similar implementation.

What is it all about? Imagine this, nowadays you are a student and you brought your phone to school. Putting it silent and it vibrate people will still here it. What to do? .... Use something that you can hear but adult can't hear it. Think about this, a ring tone that many adults cannot hear. Only if you are young, you only can hear it. :)

This was marketed as an ultrasonic teenager repellent, an ear-splitting 17-kilohertz buzzer designed to help store owner disperse young people loitering around thier stores while leaving adults unaffected.

The principle behind this biological reality that is classified as aging ear. When a person get older, most adults' ability to hear frequencies higher than that begins to deteriorate in early 30's.

What is the Mosquito Ringtone?
The short version, A tone outside the audible range of hearing for most people over the age of 30. This means that you can get phone calls and receive text messages in class or school without teachers hearing it.
