Abstract

A head-mounted wearable device (HMWD) may be fashioned that includes temples that pass near each ear of the user. A temple may incorporate a bone conduction speaker (BCS) to provide audio output to the user. During wear, a portion of the BCS is in physical contact with a head of the user to transfer the vibrations from the BCS to the user. To accommodate different head shapes and sizes, a head contact piece may be mounted to the BCS. The user may add, remove, or swap the head contact piece from an assortment of such pieces to find a profile that is comfortable to the wearer and improves performance of the BCS. The head contact piece may be magnetically affixed, allowing for easy changeout.
