Title:
A HEADSET AND A HEADPHONE
Document Type and Number:
WIPO Patent Application WO2005117487
Kind Code:
A3
Abstract:
A headset (1) and a headphone has two speakers (2, 3) connected via a headband (4) and is configured such that the headset may be used as a conventional headset or as a stereo speaker set, where the speakers of the headband and the headset constitute supports against a substrate. The headband may expediently be made of a permanently deformable material in the form of a sandwich structure, which is constructed as three layers, or may be composed of one or more rotary joints or of one or more bistable joints, which provides many possible settings of the support against the substrate, of which there may be more than one. In addition, the headset may incorporate a DSP which is adapted to received signals from a sensor sensing whether the headset is used as a conventional headset or as a stereo speaker set, and, where appropriate, sets some ether electrical circuits incorporated in the headset, which regulate volume and transmission characteristics, automatically on the basis of the sensed signals.
