During the age of COVID-19, people have needed to start remote learning/work, and a shortage of ear/headphones. I have bodged a solution for this, a amplifier designed to sit in the crevice of a laptop (music, conference) or on the lower edge of a phone (music). For a conference, slide the bottom across the crevice to the mic or speaker depending on the situation. For music on a phone, flip the direction of the cone and insert with prongs.

just a Bodge by an inexperienced person, first go at Fusion 360

The prongs go into the corresponding two parallel holes depending on the angle desired. The drop on the mainly flat section is the area for the speaker or mic. An easy way to use this is to place the flat drop on the crevice of a laptop and slide for best fit.

To use, place your ear or speak into the cone while comfortable. Make sure that the drop on the mainly flat section is on the speaker or mic.
