Subsequent Events [Abstract]
Subsequent Event	Subsequent EventOn January 27, 2020, the Board of Directors of the Company approved management’s recommendation to discontinue efforts relating to microelectromechanical systems ("MEMS") microphones. The Company estimates that its exit from MEMS microphones will result in a charge to operating expenses of approximately $22.0 million in the fourth quarter of fiscal year 2020. This charge will primarily encompass non-cash charges associated with the disposal of tangible and intangible assets related to MEMS microphones, and to a lesser extent, cash expenditures associated with severance and the settlement of prior purchase commitments for engineering materials. The Company anticipates the exit to be materially complete by the first quarter of fiscal year 2021.
