1. An acoustic device, comprising:
an operating portion configured to generate information for determination of whether a state of an earphone portion is a wearing state in which the earphone portion is worn by a user, or a non-wearing state in which the earphone portion is not worn by the user, wherein the operating portion includes a tilt sensor to detect whether the earphone portion is in the wearing state or in the non-wearing state; and
a circuitry configured to:
acquire a signal from the tilt sensor, via an analog/digital (A/D) interface coupled to the tilt sensor;
determine whether the acquired signal is within a range of preset values;
determine the earphone portion is in the wearing state based on the determination that the acquired signal is within the range of the preset values; and
implement a function based on a result of the determination that the earphone portion is in the wearing state.
