Abstract
A portable device has a portable telephone function and a music reproduction function. In a music reproduction mode, a dedicated unit receives music data from a memory and executes music reproduction processing. In addition, the dedicated unit generates vibrator vibration data based on which a vibrator output is provided in synchronism with the music reproduction. An audio output unit provides an audio output which is produced from a loudspeaker in accordance with an acoustic signal output from the dedicated unit. A peripheral output unit controls the driving of the vibrator in accordance with the vibrator vibration data output from the dedicated data.
Claims20
A portable device comprising:
- a memory configured to store digital data;
- a first output unit configured to provide an output in accordance with a reproduction signal obtained by subjecting the digital data to reproduction processing;
- a second output unit configured to provide an output in accordance with incidental data obtained by subjecting the digital data to the reproduction processing;
- a central control unit configured to execute control operations other than the reproduction processing;
- and
- a dedicated unit configured to generate the reproduction signal and the incidental data by receiving the digital data from the memory and executing the reproduction processing with respect to the digital data, the dedicated unit supplying the reproduction signal and the incidental data to the first and second output units, respectively.
A portable device comprising:
- a memory configured to store digital data;
- a first output unit configured to provide an output in accordance with a reproduction signal obtained by subjecting the digital data to reproduction processing;
- a central control unit configured to execute control operations other than the reproduction processing;
- a second output unit configured to provide an output in accordance with an incidental data signal obtained by subjecting the digital data to the reproduction processing or a control signal output from the central control unit;
- a dedicated unit configured to generate the reproduction signal and the incidental data signal by receiving the digital data from the memory and executing the reproduction processing with respect to the digital data, the dedicated unit supplying the reproduction signal to the first output unit;
- and
- a selector which selects one of the incidental data signal output from the dedicated unit and the control signal supplied from the central control unit, and supplies a selected signal to the second output unit.
A digital data reproducing method for use in a portable device including a memory for storing the digital data and a dedicated unit for reproducing the digital data, the method comprising:
- receiving the digital data corresponding to music data from the memory in a music reproduction mode;
- causing the dedicated unit to perform music reproduction processing for generating an acoustic signal from the music data;
- and
- measuring a volume level of the music data and generating incidental data which indicates the volume level.
