One embodiment provides a signal processing apparatus, including: a speaker; a vibration sensor; and a controller. The speaker is configured to output a sound. The vibration sensor is configured to detect a vibration that is caused by a solid propagation of the sound from the speaker, and to output a reference signal based on the detected variation. The controller is configured to perform a noise suppress control which suppresses a noise due to the vibration using the reference signal. |
