ISOLATION OF AUDIO TRANSDUCER

摘要

A head-mounted wearable device assembly (170) is provided that includes a bone conduction transducer (BCT) (188) and an elastomeric isolation member (304) that provides acoustic isolation between the BCT and a housing of the head- mounted wearable device assembly. The elastomeric isolation member may be a polyurethane material having a hardness (durometer) on the order of 60A. The material arrangement and durometer may be chosen to provide a frequency response and/or acoustic leakage within a predetermined range, which results in high quality sound reproduction for the wearer. The elastomeric isolation member may be secured to an interior portion (302) of the housing by a pair of mounting posts (306). The elastomeric isolation member physically and acoustically separates the BCT from the interior of the housing and other components therein.
