Abstract
A flexible arm that is configured to be located between and physically and electrically connect an acoustic module of an open-ear headphone to a battery housing of the open-ear headphone. The flexible arm defines an original resting length and position between the acoustic module and the battery housing. The flexible arm includes a flexible printed circuit that extends through the entire original resting length of the flexible arm and comprises a conductor that is configured to carry electrical energy between the acoustic module and the battery housing, and a flexible material that encases at least some of the flexible printed circuit. The length of the flexible printed circuit within the flexible arm is greater than the original resting length of the flexible arm. The flexible printed circuit can thus better accommodate tension or compression on the flexible arm as the flexible arm is bent from its original resting position.
