Abstract

A pickup device includes: a speed detector which is configured to detect speed of vibration of a soundboard of an acoustic musical instrument; and a signal generator which is configured to generate an audio signal from the speed detected by the speed detector and to output the audio signal.

Claims

1. A pickup device comprising:

a speed detector configured to detect 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.

2. The pickup device according to claim 1, wherein

the speed detector comprises at least:

an acceleration sensor configured to detect acceleration of the vibration of the soundboard of the acoustic musical instrument; and

an integrator configured to integrate an output signal of the acceleration sensor.

3. The pickup device according to claim 2, wherein the acceleration sensor is provided on the soundboard.

4. The pickup device according to claim 2, wherein the acceleration sensor is a multidimensional acceleration sensor.

5. The pickup device according to claim 4, wherein the multidimensional acceleration sensor is provided so that one direction in which the multidimensional sensor detects the acceleration is parallel with a direction of a grain from which the soundboard is formed.

6. The pickup device according to claim 1, wherein

the acoustic musical instrument is a piano, and

the speed detector is provided at a position opposed to a bridge or a sound rib with the soundboard held therebetween or provided in the vicinity of the sound rib.
