Sound-Emitting Device and Sound-Emitting Method |
| 摘要 |
A sound-emitting device includes a high-frequency extractor, adapted to accept input of a sound signal, extract high-frequency components of sound and output a high-frequency sound signal, a low-frequency extractor, adapted to accept input of the sound signal, extract low-frequency components of sound and output a low-frequency sound signal, a delay processor, adapted to delay low-frequency components of the low-frequency sound signal within a time range not causing an echo, relative to the high-frequency sound signal, to thereby output a delayed low-frequency sound signal, and a sound emitter, adapted to emit sound based on the high-frequency sound signal and the delayed low-frequency sound signal. |

1. A sound-emitting device comprising:
a high-frequency extractor, adapted to accept input of a sound signal, extract high-frequency components of sound and output a high-frequency sound signal; a low-frequency extractor, adapted to accept input of the sound signal, extract low-frequency components of sound and output a low-frequency sound signal; a delay processor, adapted to delay low-frequency components of the low-frequency sound signal within a time range not causing an echo, relative to the high-frequency sound signal, to thereby output a delayed low-frequency sound signal; and a sound emitter, adapted to emit sound based on the high-frequency sound signal and the delayed low-frequency sound signal. |
