Abstract: Methods, systems, devices and apparatuses for a sound enhancement system. The sound enhancement system includes a trailer brake control unit placed on the vehicle and an electronic control unit coupled to the trailer brake control unit. The electronic control unit is configured to determine the vehicle is operating in a tow mode based on the trailer brake status, determine a magnitude of an audio signal that mimics or enhances engine sound based on the tow mode, and generate the audio signal. The sound enhancement system further includes an audio device configured to output the audio signal based at the determined magnitude.

Abstract: An active sound generation device is proposed to generate a sound effect in a vehicle interior. The active sound generation device includes: a low sampling rate generation part, generating a low sampling rate signal by lowering a sampling rate; a processing frequency setting part, setting the sampling rate of the low sampling rate generation part; a high sampling rate generation part, amplifying a sampling rate of the low sampling rate signal to generate a high sampling rate signal as the sound effect; and a speaker, outputting the sound effect.

Abstract: The spin-air speaker is an innovative sound generation and manipulation device, primarily characterized by a modulated spinning disc with a tailored hole pattern and a mechanism for controlled airflow. This technology leverages a precision motor assembly, which includes options such as a stepper motor or a motor/encoder combination, to modulate the disc's rotation speed and pattern. The invention's uniqueness lies in its ability to produce a wide range of sound frequencies and patterns, adjustable through the disc's hole pattern. A notable application of the spin-air speaker is in the field of fire suppression, where it utilizes specific sound frequencies to target and extinguish fires by achieving what is termed a “Pyrosonic lock” on the fire's fundamental and harmonic frequencies. The spin-air speaker's versatility extends to generating musical notes and melodies, and its capability to produce sounds below the human hearing range opens up possibilities for various non-entertainment applications, including but not limited to fire extinguishment.

Abstract: In a sound system that uses over-the-air (OTA), a blockchain platform server is configured to support performance of a virtual sound transaction in a virtual environment. An OTA server is configured to manage a virtual sound transmitted from the blockchain platform server. A vehicle communication control device is configured to perform wireless communication with the OTA server. The vehicle communication control device is configured to download the virtual sound from the OTA server, determine whether the virtual sound is similar to a predetermined specific sound, perform an OTA state test of the virtual sound when the virtual sound is not similar to the predetermined specific sound, and control a sound processing device to play the virtual sound when the virtual sound passes the OTA state test.

Abstract: A zipper for a reclosable bag includes an elongated groove profile having two arms which form a general U-shape to define an opening to a channel, and an elongated rib profile opposing the groove profile. A plurality of first segments of the rib profile alternate with a plurality of second segments of the rib profile to create a structural discontinuity along a length thereof. During interlocking of the groove and rib profiles, an audible clicking sound of at least 50 dB on average is created during opening and closing.

Abstract: A method for controlling a tone of an electric vehicle (EV) based on motor vibration may include: calculating an order component from a vibration signal of an EV motor of an electric vehicle, extracting a first order component with the greatest linearity for motor output torque among the calculated order component, then calculating an order frequency by transforming revolutions per minute (RPM) of the EV motor into frequency, setting an EV mode tone by applying a vibration level of the first order component to a level of the order frequency to be output and rearranging the order component, and outputting the set EV mode tone, and may apply an LMS filter algorithm, FFT/IFFT transforms, and an order tracking algorithm in extracting the first order component.

Abstract: A system for levitating a softened, viscous or viscoelastic material by near field acoustic levitation. The system includes a support structure having a rigid surface, and a vibration generator operatively connected to the rigid surface. The vibration generator transmits acoustic waves to the rigid surface at a frequency and an amplitude sufficient to vibrate the rigid surface and create a gas squeeze film between the material and the rigid surface. The gas squeeze film has a pressure greater than ambient air pressure and sufficient to levitate the material. The system is particularly suited for transporting, forming, or casting heated glass. Also disclosed are methods for transporting, forming, and casting heated glass using near field acoustic levitation.
