In order to use this app, you need to have an understanding of how the speaker works.

Let’s take a look at how your smartphone’s speaker operates.

When your smartphone is on, the vibrator of the speaker vibrates the voice coil.

The voice coil connects to the diaphragm which vibrates when the voice coil is attached.

When the voice coil is no longer attached, the diaphragm no longer vibrates, thus not making a sound.

When the diaphragm moves, it creates a pressure wave that travels through a waveguide.

This wave is the same wave that is used to transmit sound waves through the air.

You can use this app to remove water from your speaker.

A sound frequency is generated to extract water.

A sine wave frequency is generated which is suitable for specific speakers.

The frequency can be adjusted using the slider.
