how to influence or invalidate data acquired from the accelerometer sensor of a smartphone or embedded system using sounds

During several tests it is observed that not all the frequencies emitted influence the data acquired by the accelerometer and are not due to vibrations on the smartphone body as they are sinusoidal.

in the video there could be conversion errors that they do not sync the audio and images correctly ... sorry ...

block, freeze or void data of magnetometer sensor or magnetic field sensor of smartphone or embedded system using a very powerful magnet.

Dangerous! it could break the hardware of your device!

Personally I have observed very strange behaviors, bugs, blocks of various devices where the field is very strong. The OnePlusOne smartphone when approached to a very strong magnetic field in a precise point activates the screen lock.

Do not experiment if you are not aware of the risk!

I do not consider myself responsible for any damage!
