PROBLEM TO BE SOLVED: To provide an acoustic device which can appropriately improve operability. SOLUTION: An arithmetic processing part sets an initial value '1' in a variable (n) (step S31) and selects the n-th source of a source selection table, defining an audio source being a switch object and its order (step S32). The arithmetic processing part adds '1' to the variable (n), when a source key instructing the switch of the audio source is discriminated to have been depressed (step S34) and discriminates whether the n-th source in the source selection table is a 'table terminal' (step S35). When it is discriminated as not being the 'table terminal', the arithmetic processing part returns the processing to the step S32. When it is discriminated to be the 'table terminal', the processing is returned to the step S31 and the processing is repeated.
