1. A pickup device comprising:
- a speed detector configured to detect a speed of vibration of a soundboard of an acoustic musical instrument; and
a signal generator configured to generate an audio signal from the speed detected by the speed detector and to output the audio signal,wherein the speed detector includes;
an acceleration sensor configured to detect an acceleration of the vibration of the soundboard of the acoustic musical instrument and output a first component of the acceleration, a second component of the acceleration, and a third component of the acceleration;
an adder configured to add the first component of the acceleration, the second component of the acceleration, and the third component of the acceleration and to output an addition signal indicating the result of the addition; and
an integrator configured to integrate the addition signal.
