Latest Patents

One of Välimäki's latest patents is titled "Controlling Reproduction of Sound and Vibration." This patent describes a signal processing assembly that includes a signal processing portion for deriving an output signal based on an input signal. The control portion of this assembly is designed to manage the derivation of the output signal for rendering by sound and vibration reproduction apparatus. It allows for separate control of amplifications in tactile and audible frequency bands, adapting to user preferences and signal content types.

Another notable patent is the "Method for Designing a Modal Equalizer for Low Frequency Sound Reproduction." This patent addresses the challenges of controlling long decays in rooms with strong low-frequency modes. Välimäki presents a systematic methodology for active modal equalization, proposing two methods to correct modal decay behavior in loudspeaker-room systems. The first method modifies the primary sound to control modal decays, while the second method employs separate radiators to achieve the same effect.
