摘要： A sound generator (100) mounts on a vehicle to manipulate vehicle noise originating from a vehicle operated by an internal combustion engine. The sound generator (100) includes a casing (110), a loudspeaker (120), and at least one pressure compensation valve (130). The loudspeaker (120) and the casing (110) together thereby enclose a volume (115). Further, the pressure compensation valve (130) couples the volume (115) enclosed by the loudspeaker (120) and the casing to an outside of the casing (110). The pressure compensation valve (130) thereby extends through a plane in which the loudspeaker (120) is located. A system (200) for manipulating sound waves propagating through exhaust systems of vehicles driven by an internal combustion engine uses the above sound generator (100).

摘要： The various embodiments set forth an active noise cancellation system that includes a source separation algorithm. The source separation algorithm enables the identification of acoustic inputs from a particular sound source based on a reference signal generated with one or more microphones. Consequently, the identified acoustic inputs can be cancelled or damped in a targeted listening location via an acoustic correction signal, where the acoustic correction signal is generated based on a sound source separated from the reference signal. Advantageously, the reference signal can be generated with a microphone, even though such a reference signal may include a combination of multiple acoustic inputs. Thus, noise sources that cannot be individually measured, for example with an accelerometer mounted to a vibrating structure, can still be identified and actively cancelled.

摘要： The technology described herein can be embodied in a computer implemented method that includes detecting, by one or more processing devices, onset of an unstable condition in an active noise control system. The method also includes obtaining, responsive to detecting the onset of the unstable condition, updated filter coefficients for a system-identification filter configured to represent a transfer function of a secondary path of the active noise control system. The updated filter coefficients are generated using a set of multiple subband adaptive filters, wherein filter coefficients of each subband adaptive filter in the set are configured to adapt to changes in a corresponding portion of a frequency range associated with potential unstable conditions in the active noise control system. The method also includes programming the system identification filter with the updated coefficients to affect operation of the active noise control system.

摘要： Differing from conventionally-used exhaust pipe utilizing discontinuous section area(s) and sound-absorbing material(s) to abate the noise produced by an engine, the present invention provides a waste air exhausting device consisting of: a housing, a supporting plate disposed in the housing, a miniature microphone disposed at the end of the housing, and a loudspeaker disposed on the supporting plate. Therefore, according to the noise produced by the engine, a noise controller system coupling to the miniature microphone and the loudspeaker is able to produce an anti-noise signal through the loudspeaker for abating the engine noise. On the other hand, the noise controller system can also produce an anti-noise signal having specific frequencies components according to the frequency of the engine noise and a reference signal, so as to modulate the frequency of the engine noise by broadcasting the anti-noise signal having the specific frequencies components in the housing through the loudspeaker.

摘要： Some embodiments are directed to a control system for a sound controller configured to transmit sounds to a vehicle passenger cabin. The system includes a downshift sensor configured to detect a downshift of a vehicle transmission, and an accelerator pedal sensor that is configured to detect whether an accelerator pedal is actuated above a predetermined threshold. A controller controls operation of the sound controller in accordance with a sound control logic that is based on vehicle engine mode, transmission gear selection, accelerator pedal position, and vehicle engine speed. The controller also controls operation of the sound controller in accordance with an audible downshift logic if the downshift sensor detects a downshift of the vehicle transmission and the accelerator pedal sensor detects that the accelerator pedal is not actuated above the predetermined threshold, the audible downshift logic controlling the sound controller to enhance engine sound transmitted to the passenger cabin.
