摘要： A vehicle system includes a non-transitory computer-readable storage medium having instructions stored thereon. The instructions, upon execution by one or more processors, cause the one or more processors to store a plurality of passenger profiles regarding passengers of a vehicle, acquire passenger identifying data regarding a present passenger in the vehicle, identify a respective passenger profile associated with the present passenger from the plurality of passenger profiles based on the passenger identifying data, and control a speaker positioned within the vehicle based at least in part on a pre-stored physical characteristic included with the respective passenger profile to emit noise-canceling sound waves to generate a noise suppression zone to suppress sound waves perceived by the present passenger. Each of the plurality of passenger profiles includes the pre-stored physical characteristic of a respective passenger associated therewith.

摘要： Seats that include sound cancelation systems are described. An example vehicle bench seat has a first backrest, a first speaker, a second backrest, a second speaker, a central portion, and a seat base. The first speaker is disposed within the first backrest and the second speaker is disposed within the second backrest. Each of the first and second speakers emit primary sound waves and secondary sound waves. The secondary sound waves of the first speaker are 180 degrees out of phase with the primary sound waves of the first speaker and the secondary sound waves of the second speaker are 180 degrees out of phase with the primary sound waves of the second speaker. The central portion includes channels that direct the secondary sound waves emitted by the first and second speakers into the vehicle cabin to cancel undesired primary sound waves.

摘要： Active noise control (ANC) is performed within a vehicle. Suppressed sound is produced by suppressing frequencies of ambient sound above a threshold frequency that enter an interior cavity of a sound-suppressing enclosure disposed within, and spaced from, interior walls of the vehicle. A microphone disposed within the interior cavity of the sound-suppressing enclosure receives feedback comprising a combination of the suppressed sound produced by the sound-suppressing enclosure and antinoise produced by one or more speakers mounted to a headrest disposed within the interior cavity of the sound-suppressing enclosure. The speakers are controlled to produce the antinoise based on the feedback, such that the antinoise destructively interferes with frequencies of the suppressed sound that are above the threshold frequency.

摘要： A method is provided for attenuating road noise in a vehicle cabin. The method includes filtering a noise signal representative of road noise with a first fixed filter to provide an attenuation signal, and filtering the attenuation signal with an adaptive filter to provide a first filtered attenuation signal. The first filtered attenuation signal is provided to an electro-acoustic transducer for transduction to acoustic energy, thereby to attenuate the road noise in a vehicle cabin at an expected position of an occupant's ears. The method also includes receiving a microphone signal representative of the acoustic energy, filtering the attenuation signal with a second fixed filter to provide a second filtered attenuation signal, and updating a set of variable filter coefficients of the adaptive filter based on the microphone signal and the second filtered attenuation signal to accommodate for variations in a transfer function of the speaker.

摘要： The present invention provides an electronic helmet for cancelling noises, which comprises a helmet including a plurality of microphones, a plurality of speakers and a first communication unit; and a mobile device including a second communication unit and a control unit. When the first communication unit in the helmet connects to the second communication unit in the mobile device, the control unit generates a plurality of control signals according to at least one sound or noise detected by the plurality of microphones. The mobile device uses the plurality of control signals to control the plurality of speakers outputting the at least one sound or anti-noise cancelling the noise. By the above electronic helmet, the present invention also provides a method integrating active noise control, hands-free communication, music listening, and voice navigation so as to achieve the proposes of cancelling the noises and improving the riding quality.

摘要： In order to enable noises entering the ear from random directions to be muted without wearing headphones, this muting device is provided with: a super-directional microphone that detects noises in spot areas around the ear at pinpoints; and an ultrasonic speaker that modulates and outputs a carrier signal supplied by a transmitter according to noise signals detected by the super-directional microphone. Furthermore, an adaptive filter is provided, and the adaptive filter supplies noise signals with the opposite phase to noises detected by the super-direction microphone, and transmits an ultrasonic signal from the ultrasonic speaker toward the eardrum of a human.
