Application: Acoustic metamaterial device, method and computer program (Patent ID: US20240107224A1)

The patent filed by Sony Group Corp describes a device that includes an acoustic metamaterial (AMM) designed to reduce the phase velocity of acoustic waves at low frequencies compared to higher frequencies. The device also features a microphone array embedded within the AMM, consisting of at least two microphones, to detect acoustic waves. The AMM enhances the directivity of the microphone array at low frequencies while maintaining performance at high frequencies, improving the overall functionality of the device.

The claims associated with the patent outline specific features and functionalities of the device, such as the significant reduction in phase velocity of acoustic waves at low frequencies within the AMM compared to the surrounding medium. The device also includes various components like resonators, Helmholtz resonators, membranes, and quarter wavelength resonators within the AMM to achieve the desired acoustic properties. Additionally, the patent covers the use of a processor to evaluate signals received by the microphone array and create a directivity pattern, as well as a computer-implemented method for receiving and evaluating signals from the device. Overall, the patent highlights the innovative design and functionality of the device incorporating AMM technology for improved acoustic wave detection and directivity.
