    • A method and system for providing a sound source suitable for an exercise state of a user by recognizing the exercise state of the user by measuring heart rate and exercise speed of the user. The method includes: determining a standard heart rate; measuring a heart rate of a user; measuring an exercise speed of the user; comparing the measured heart rate and the standard heart rate; when a difference between the both heart rates is more than a predetermined value, generating compensated exercise speed information based on the difference and the measured exercise speed; and replaying a sound source according to the compensated exercise speed information. According to the exercise state management method, heart rate suitable for the type, intensity, or time of exercise selected by the user and a sound source suitable for exercise speed are provided, thereby improving satisfaction and effectiveness of the exercise.

    • In the electric-acoustic transducer, first to third permanent magnets are respectively received in the first to the third recesses of a yoke, so as to generate non-alternating magnetic fields. The first and second magnetic gaps are formed between the yoke and the first and the second plates. The first and the second coils are respectively disposed in the first and the second magnetic gaps, to generate alternating magnetic fields of the same phase, when an electric driving signal is applied from the exterior. The electric-acoustic transducer achieves reproduction of a broad frequency band with high power and high efficiency, even with an ultra slim or small dimension, proper for a small electronic appliance such as a notebook computer, by employing dual voice coil drivers and auxiliary magnetic circuits.
