ACTIVE NOISE CONTROL SYSTEM WITH AN ELONGATED TRANSMISSION MEMBER
摘要
An active noise control system includes a speaker (30) located within an enclosure (36) within a vehicle body component. The speaker enclosure is typically located forward of a vehicle wheel well. An elongated transmission member (46) communicates canceling noise from the speaker enclosure over the wheel well to an outlet adjacent the firewall (42). The elongated transmission member focuses and directs cancellation noise toward the firewall and bypasses the wheel well and any restriction created thereby.
