Title:
NONLINEAR CONTROL OF A LOUDSPEAKER WITH A NEURAL NETWORK
Document Type and Number:
WIPO Patent Application WO/2022/092741
Kind Code:
A1
Abstract:
An electronic device is provided. The electronic device includes a memory storing at least one instruction, and a processor electronically connected with the memory, wherein the processor is configured to, by executing the instruction, input into a first layer of a neural network at least one data sample of a current displacement of one or more moving components of a loudspeaker and at least one or more other data samples of one or more prior displacements of the one or more moving components, generate in the first layer a data vector by applying a nonlinear activation function based on the at least one data sample of the current displacement and the at least one or more other data samples of the one or more prior displacements, input into a second layer of the neural network the data vector and applying an affine transformation to the data vector, and output a prediction of a current voltage to apply to the loudspeaker based on the affine transformation applied to the data vector.
