摘要： A sound bar having a mounting assembly configured to pivotally secure the bar. The sound bar includes an elongated, at least partially hollow, housing. The housing has a body extending between two opposing ends. A speaker array is positioned in the body. At least one speaker is positioned in at least one end of the bar. The end speaker(s) are preferably bass speakers in fluid communication with the hollow housing. A grill is preferably positioned over at least one of the housing ends. The grill preferably has a center hub affixed to an outer rim by spokes defining open spaces in the grill to facilitate the emission of sound. A mount is attached to the sound bar to secure the bar to a structure while allowing the bar to pivot along its longitudinal axis. Preferably, the mount is secured to the center hub of the grill.

摘要： A method of generating a tire slip sound is capable of producing a virtual tire slip sound in a driving situation in which tire slip may occur during vehicle driving. The method includes collecting vehicle driving information while a vehicle is traveling; determining a characteristic of a virtual tire slip sound based on the collected vehicle driving information; generating and outputting a tire slip signal for generating and outputting the virtual tire slip sound according to the determined characteristic; and operating sound equipment of the vehicle according to the tire slip signal output from the controller to generate and output the virtual tire slip sound according to a vehicle driving state.

摘要： An audio processing system includes: a first microphone configured to output a first signal based on a first audio signal; one or more microphones each of which outputs a microphone signal based on an audio signal; one or more adaptive filters configured to respectively receive the microphone signals from the one or more microphones and output passing signals based on the microphone signals; and a processor configured to: determine whether the microphone signal includes uncorrelated noise; control one or more filter coefficients of the one or more adaptive filters; and subtract a subtraction signal based on the passing signals from the first signal. The one or more microphones include a second microphone that outputs a second signal. When determining that the second signal includes the uncorrelated noise, the processor is configured to set a level of the second signal input to the corresponding adaptive filter to zero.
