Patent Review: Multiple Path Acoustic Wall Coupling for Surface-Mounted Speakers
This article reviews a patent awarded to Paul Wayne Peace Jr. and Derrick Rodgers, on behalf of Harman International Industries. The patent describes a surface-mounted loudspeaker design that mitigates the interference between direct low-frequency (LF) energy and reflected LF energy by breaking the LF energy from an LF driver into multiple paths using one or more of waveguides, driver load plates, and enclosure ports to diffuse the reflected energy and minimize frequency response errors.
Wireless Audio: Ultra-Low Latency Audio Transmission Over Bluetooth LE Audio
While Bluetooth technology does not provide a complete solution for live performance audio, it still has a key role to play. In particular, the value of a standards-based approach manifests with the availability of low-cost Bluetooth LE-compatible transceivers from a variety of SoC vendors. Building on these readily available devices, manufacturers can engineer systems that are strongly optimized for live and professional applications. But what latency performance targets should those products meet?
