Acoustic structure including helmholtz resonator |
摘要 |
In a bass reflex type speaker, a Helmholtz resonator is formed by a bass reflex port and a space within a speaker enclosure excluding the bass reflex port and a speaker unit. The bass reflex port of the bass reflex type speaker is movable toward and away from a side surface while maintaining its projecting direction within the speaker enclosure. In response to such movement of the bass reflex port, relative positional relationship between a neck and cavity of the bass reflex type speaker varies. |
