A recently granted patent (Publication Number: US11924605B2) discloses a playback device with unique features designed to enhance audio playback quality. The device includes an elongated body with forward and upper surfaces, housing forward-firing and up-firing transducers that direct sound along different axes. A waveguide, in fluid communication with the up-firing transducer, features a sidewall with varying dimensions to optimize acoustic energy distribution. Specifically, the design ensures that during audio playback at 2000 Hz, the ratio of acoustic energy along different axes meets specified criteria, enhancing the overall audio experience.

Furthermore, the patent details additional configurations for the playback device, including variations in the sidewall design, the angle between different sound axes, and the height variations of the waveguide. These features aim to improve the playback quality by controlling the distribution of acoustic energy and optimizing the audio output. By strategically aligning the components and adjusting the dimensions of the waveguide, the playback device offers a unique audio experience with enhanced clarity and balance across different frequencies. Overall, the patented playback device showcases innovative design elements that contribute to a more immersive and high-fidelity audio playback experience for users.
