Adjustable Headphone Neck Band

Abstract:

Bone conduction headphones include a transducer and a neck band. The transducer is configured to convert an electrically provided audio signal into mechanical vibrations. The neck band includes a curved base section and two leg sections extending from the curved base section, providing a substantially U-shaped space to accommodate a listener's head between the two leg sections. The transducer is disposed on the neck band at a distal end of one of the leg sections, and the neck band applies a clamping force on the listener's head. The clamping force establishes a mechanical interface for transmission of the mechanical vibrations from the transducer to a cranial bone of the listener's head. The bone conduction headphones also include a clamping force adjuster enabling an adjustment of the clamping force of the neck band.
