Sony patents method to map sound paths in gaming controllers
Sony has been granted a patent for a system that calculates how sound travels between different parts of an input device, such as a controller. The system identifies the physical locations of microphones and sound-producing elements to measure how audio is weakened, resonated, or changed in frequency as it moves through the device.
In the filing’s own words
A system for generating a transfer function indicating audio transmission characteristics of an input device associated with a processing device includes: a parameter determining unit configured to determine one or more parameters of the input device, where the parameters include a location of a microphone associated with the input device and a location of one or more respective input and/or output elements associated with the input device, an audio characteristic determining unit configured to determine one or more characteristics of audio transmission between respective input and/or output elements and the microphone, where the characteristics include one or more of an attenuation, resonance, and/or change in frequency profile of audio associated with the respective input and/or output element, and a transfer function generating unit configured to generate a transfer function in dependence upon the determined audio characteristics.
What exactly they claim (claim 1)
1. A system for generating a transfer function indicating audio transmission characteristics of an input device associated with a processing device, the system comprising: a parameter determining unit configured to determine one or more parameters of the input device, wherein the parameters include a location of a microphone associated with the input device and a location of one or more respective input and/or output elements associated with the input device; an audio characteristic determining unit configured to determine one or more characteristics of audio transmission between an input and/or output element and the microphone, wherein the characteristics include one or more of an attenuation, a resonance, or a change in frequency profile of audio associated with the input and/or output element, wherein the audio associated with the input and/or output element comprises audio created by the input and/or output element; and a transfer function generating unit configured to generate the transfer function in dependence upon the determined audio characteristics.
