There are provided a mobile device that is equipped with a musical composition-reproducing section and capable of curtailing the battery drain as much as possible, and a mobile device that prevents the quality of reproduced musical tones from being degraded even if the voltage level of the battery lowers. A battery voltage detector monitors an voltage level of a battery. The musical composition-reproducing section is controlled such that the number of parts of the musical composition reproduced by the musical composition-reproducing section is reduced when the monitored voltage level of the battery becomes lower than a reference value. In other forms of the invention, when the monitored voltage level of the battery becomes lower than a reference value, a first predetermined number of parts of the musical composition data are assigned to intrinsic ones of a larger second predetermined number of parts that correspond to the first predetermined number of parts of said musical composition, as well as to other ones of the second predetermined number of parts than the intrinsic ones, for reproduction of the musical composition, or the gain of a variable-gain amplifier is increased to compensate for the lowering of the volume of the reproduced parts.
A mobile device comprising:
A mobile device comprising:
A volume compensating method for a mobile device having musical composition-reproducing circuitry that reproduces a musical composition composed of a first predetermined number of parts, said musical composition-reproducing circuitry being capable of reproducing a second predetermined number of parts, the second predetermined number being larger than the first predetermined number, and a power supply that supplies power to said musical composition-reproducing circuitry, the volume compensating method compensating for lowering of a volume of musical tones reproduced by the mobile device, the method comprising the steps of:
A storage medium storing a program that can be executed by a computer, the program being capable of realizing a volume compensating method for a mobile device having musical composition-reproducing circuitry that reproduces a musical composition composed of a first predetermined number of parts, said musical composition-reproducing circuitry being capable of reproducing a second predetermined number of parts, the second predetermined number being larger than the first predetermined number, and a power supply that supplies power to said musical composition-reproducing circuitry, the volume compensating method compensating for lowering of a volume of musical tones reproduced by the mobile device, the method comprising the steps of:
A storage medium storing a program that can be executed by a computer, the program being capable of realizing a volume compensating method for a mobile device having musical composition-reproducing circuitry that is capable of reproducing a musical composition composed of a plurality of parts, said musical composition-reproducing circuitry having volume control circuitry for controlling a volume level of the reproduced plurality of parts, and a power supply that supplies power to said musical composition-reproducing circuitry, the volume compensating method compensating for lowering of a volume of musical tones reproduced by the mobile device, the method comprising the steps of:
A mobile device comprising:
