Title:
SYSTEMS FOR GENERATING AUDIO SIGNALS AND ASSOCIATED METHODS
Document Type and Number:
WIPO Patent Application WO/2018/215841
Kind Code:
A3
Abstract:
The present disclosure is directed to methods, devices, and systems for playing audio signals associated with an electric vehicle. The method includes, for example, (1) determining a speed of the electric vehicle; (2) receiving, from a memory, a plurality of sound frequency characteristics corresponding to the determined speed of the electric vehicle; and (3) generating an audio signal segment corresponding to the received sound frequency characteristics by a speaker of the electric vehicle. The sound frequency characteristics include a plurality of segments. Each of the segments includes an amplitude of a number of frequency characteristics in a sound produced by a powertrain assembly (e.g., an electric motor) in a speed range.
