Summary: Howling principle
The monolithic capacitor has a piezoelectric property of a ceramic having a high dielectric constant, and the circuit board vibrates in a planar direction when an alternating voltage is applied. (The amplitude of the chip and board is only about 1 pm to 1 nm)
When the amplitude period of the board reaches the frequency band (20Hz ~ 20kHz) that people can hear, the sound can be recognized by the human ear.
