Patent ID: 8315406

Claim:
A music reproducing system comprising: a music reproducing unit; and a transducer unit connected to the music reproducing unit; wherein the transducer unit comprises: a transducer to convert an audio signal to acoustic audio, a main sensor to detect a motion state or a biometric state of a listener to which the transducer unit is attached, and an attachment-state detecting unit that produces an output value that changes between a first value and a second value on the basis of whether the listener makes contact with the transducer unit, and wherein the music reproducing unit comprises: an information processing part to perform information processing regarding reproduction of music according to an output signal from the main sensor, and a detection controller to determine from the output value from the attachment-state detecting unit whether the transducer unit is in an ongoing-attachment state, in which the transducer unit is being attached or reattached to the listener, or in an attachment-complete state, in which the transducer unit has been attached to the listener, to make the output signal from the main sensor ineffective or suppressing the output signal during a period in which the transducer unit is determined to be in the ongoing-attachment state, and to cancel ineffectiveness or suppression when the transducer unit is determined to be in the attachment-complete state.
