VEHICLE ACCESSORY MICROPHONE |
摘要 |
A microphone assembly includes one or more transducers (2210) that are positioned in one or more housings. A preprocessing circuit (2215) includes a inverted comb filter (2245) for eliminating predetermined frequencies between harmonics of the human voice in a predetermined frequency range. A processing circuit (2220) coupled to the preprocessing circuit (2215) is used for outputting an electrical signal such that the transducers (2210) used in combination with the processing circuit (2220) very effectively cancels noise. The microphone assembly can be employed in a vehicle accessory such as a vehicular mirror. |
