Earplug and manufacturing method |
摘要 |
An earplug that includes a piezoelectric element that converts electrical signals into oscillations; and a deformable material of which at least one segment is insertable into an external auditory canal of a person to ensure an acoustic seal by deformation, the piezoelectric element being disposed inside the deformable material and in fixed contact therewith, the deformable material being able to transmit the oscillations at a periphery and ensure conduction of the oscillations through cartilage and soft tissue of the auditory canal.
