    Abstract: The present disclosure generally provides an apparatus and method of forming a pressure equalizing audio speaker that can be easily manufactured and provides a high quality audio output. One or more of the embodiments of the disclosure provided herein include a sealed enclosure that has at least one liquid impermeable and gas permeable region that allows the flow of a gas between an interior region and an exterior region, while preventing or substantially inhibiting the movement of a liquid from the exterior region into the internal region. In general, the liquid impermeable and gas permeable regions are configured to allow slowly changing gas pressures registered between the internal region and exterior region to be relieved, while allowing rapidly changing gas pressures generated by the diaphragm at audible frequencies to function at a desired level during use.

    Abstract: Embodiments of the disclosure may include a method and apparatus for improving the efficiency and extending the operation time between recharges or replacement batteries of a portable audio delivery system. The audio delivery system may include a processor, an audio processing device, a speaker, and a rechargeable power source. The audio delivery system is generally configured to generate and/or receive an audio input signal and efficiently deliver an amplified, high quality audio output signal to a user. In some embodiments of the disclosure, the audio processing device of the audio delivery system may include a switch mode power supply (SMPS), a signal delay element, an envelope detector, and a switching signal amplifier.
