Ambient noise removal device |
摘要 |
An ambient noise removal device includes: a sound signal output section that outputs a sound signal to thereby drive a speaker; a noise detection section that detects an electromotive force produced in the speaker by ambient noise; and a noise cancellation section that generates, on the basis of the electromotive force, a signal of an opposite phase from the ambient noise and adds the generated signal to the sound signal to thereby cancel the ambient noise.
