What is a sound wave? Sound waves are mechanical longitudinal waves
that propagate in elastic media, with frequencies ranging from 20
to 20000 Hz and can be heard by the human ear
The working principle of a sonic toothbrush is to rely on the
high-speed motion of a micro motor to drive the toothbrush head to
swing left and right at high speed, generating mechanical
vibration, which is the generation of sound waves
The suitable vibration frequency for acoustic toothbrushes is
between 166-666Hz (10000-370000 times/minute), and different
frequencies of acoustic toothbrushes achieve varying degrees of
tooth cleaning effects. The cleaning effect of acoustic
toothbrushes is proportional to the frequency and amplitude of
sound waves
Ultrasound is a type of sound wave with a frequency higher than
20000Hz, which has good directionality and strong penetration
ability, but cannot be heard by the human ear. The high-frequency
vibration of sound waves can cause the water in the mouth to form
countless invisible, extremely small bubbles and cause them to
burst, which generates enormous energy. Tooth tartar, dental
plaque, dental calculus, and other substances can be destroyed by
the energy generated by the cavitation effect and separated from
the teeth, thereby achieving a dental cleaning effect. Because
these small bubbles can penetrate into all subtle corners of the
oral cavity, the cleaning range of ultrasonic tooth cleaning can
cover various parts of the periodontal area.
