Abstract: Eyewear includes at least a temple having a cavity open to the outside through first and second holes positioned opposite each other along a transversal direction. The eyewear includes a speaker assembly mounted inside the cavity, which has a speaker operable to reproduce a sound, a speaker enclosure that houses the speaker and a processing unit configured to control the operation of the speaker. The speaker includes a diaphragm designed to move in order to produce the sound, the diaphragm dividing an internal volume of the speaker enclosure into front and back cavities that are open to the outside of the speaker enclosure respectively through front and back openings. The speaker assembly is mounted inside the cavity to create an air communication between the front opening and the first hole and between the back opening and the second hole. The back opening is positioned to directly face the second hole.

Abstract: Methods and apparatus are provided for automatically adjusting, by an audio device, the SPL of its audio output. As described herein, the SPL is adjusted based on detected ambient noise. According to aspects, audio device iteratively adjusts the SPL based on the ambient noise. According to aspects, the SPL is adjusted to be greater than the ambient noise by a threshold SPL amount. According to aspects, the audio device outputs sound in substantially a first direction and the microphone detects sound substantially outside of the first direction. The adjusted sounds are output by the audio device.

Abstract: An absorbent product is useable as an absorbent material for cleaning spills or as a plant growth medium for improved moisture retention. A method includes processing a raw coir feedstock to pieces of a predetermined size and compressing the pieces at a predetermined temperature and pressure. The resulting pieces are cooled for a predetermined time to an ambient temperature and broken to a predetermined size. The resulting pieces are mixed with coir fines from the crumbling process at a predetermined ratio to form a final absorbent product.
