Notes

(1)

This subclass covers arrangements for generating mechanical vibrations in solids, e.g. for the purpose of performing mechanical work. [6]

(2)

This subclass does not cover arrangements for generating mechanical vibrations in fluids, which are covered by subclass G10K. [6]

Processes or apparatus for generating mechanical vibrations of infrasonic, sonic or ultrasonic frequency

making use of electrical energy (B06B 1/18, B06B 1/20 take precedence)
