1. An acoustic input apparatus, comprising:
a first acoustic source, configured to generate a first acoustic wave, in response to a user performing a first operation;
an acoustic transducer, configured to collect an acoustic wave and convert the collected acoustic wave into an electrical signal reflecting a frequency of the collected acoustic wave; and
a comparing circuit, configured to receive the electrical signal, determine whether the collected acoustic wave comprises the first acoustic wave based on whether the frequency meets a first preset condition, and output an operating signal;
wherein the first preset condition is determined based on a first frequency of the first acoustic wave; and
wherein the operating signal is in a first state in response to the collected acoustic wave being determined to comprise the first acoustic wave,
wherein the acoustic source comprises a toothed wheel, and the first operation is rolling the toothed wheel, when the toothed wheel rotates, the first acoustic source generates the first acoustic wave, whose frequency component is in proportion to a rotation speed of the toothed wheel.
