Abstract: Devices and methods described herein relate to novel and improved speaker assembly designs that optimize audio quality. Embodiments herein can also facilitate the tuning of audio range by linearizing frequency and amplitude. Some speaker assembly embodiments herein can improve the audio output by alternating layers of rigid and porous material, which can facilitate aperiodic resonance damping. Embodiments herein can also provide a constant audio output and improve the audio directional pattern. Moreover, speaker assemblies herein can improve the overall audio output at all frequencies by eliminating internal acoustic cavity resonance. Embodiments herein can also customize the audio output through tunable or adjustable components, such as modifying the flow resistance, density, thickness, or shape of cabinet layers. This can also shape the directional frequency response and adjust the damping or resonance frequency.

Abstract: Devices and methods described herein can comprise novel and improved designs and layouts to optimize the structural integrity and efficiency in speaker drivers. Embodiments of the present disclosure can also include a speaker driver comprising novel and improved component design which can optimize the performance and specifications of the device. Embodiments according to the present disclosure can include novel inverted dome designs which can improve the structural integrity of the speaker driver. Dome designs can also provide strategic structural reinforcement devices. Embodiments herein can include dome edges which can bend back to form a type of trough to build a reinforcement ring with a negligible mass addition. In this manner, speaker drivers described herein can provide novel and improved features which simplify the manufacturing process, lower the manufacturing cost, and/or reduce the overall weight of the device.
