OFFSET BAFFLES FOR ACOUSTIC SIGNAL ARRIVAL SYNCHRONIZATION |
摘要 |
Offset baffles are provided in a speaker for acoustic signal arrival synchronization. The speaker includes an enclosure. The enclosure includes a first side positioned at an angle with respect to a horizontal axis or plane. The first side includes an upper portion and a lower portion. The upper portion and the lower portion are offset from one another by a first offset in a first direction and a second offset in a second direction. The first offset in the first direction and the second offset in the second direction define a vent extending across a width of the first side. The vent is positioned above a low-frequency transducer and below a high-frequency transducer. The low-frequency transducer is mounted to the lower portion and generates a first acoustic signal within a first frequency range. The high-frequency transducer is mounted to the upper portion and generates a second acoustic signal within a second frequency range. The low-frequency transducer and the high-frequency transducer are displaced by the first offset in the first direction and the second offset in the second direction to adjust a low-frequency transducer acoustic origin position and a high-frequency transducer acoustic origin position. The upper portion and the lower portion configured such that a first acoustic signal arrival time and a second acoustic signal arrival time are synchronized in a listening area
