An arcuate central band piece has coupled thereto at both ends arcuate side band pieces of the same curvature of the central band piece by coupling means, forming a substantially circular headphone band as a whole. Each of the coupling means is arranged so that the side band pieces can be turned about axes lying in the plane formed by the band pieces, by which the headphone band can be folded in thirds. A receiver is attached to each of the side band pieces.
A simple combination handset and headset device includes an elongated, preferably flexible body with a mouthpiece at one end thereof and an earpiece at the other end thereof, and a tubular arm pivotally connected to the mouthpiece for rotation between handset and headset positions, whereby, when the arm lies against the body, the combination can be used in the same manner as a conventional handset, and when the body is extended and the arm rotated, the combination can be used as a headset.
A headband comprises first and second headbands having their one ends pivotally interconnected and being foldable about their pivotal interconnection inwardly and outwardly in a single plane and having opposite ends with an earpiece carried thereby. Each of the headbands include at least three separate parts telescopically interengageable and which are of substantially equal lengths. Advantageously the central part may be made of plastic and includes a tubular portion into which the next adjacent part is telescopical. The tubular portions are advantageously provided at each end of the central part to permit a telescopic movement of each of the other parts into the middle part.

According to the invention a headphone set comprises a hoop band, to each of the two ends of which is fixed a respective acoustic transducer and which extends accurately in a plane, with at least one joint for folding the ends of the hoop band inwardly in the plane and an elastic region for resiliently expanding and narrowing the hoop band is either characterized in that the fixing of each of the transducers to the ends of the hoop band has a joint for pivoting the transducers into the plane and that arranged in the region of the two ends of the hoop band is a respective connecting structure which can be connected to each other and which then in co-operating relationship hold the folded-in ends of the hoop band in a crossed position or that the one joint for folding the ends of the hoop band inwardly is arranged at the apex of the hoop band, that the headphone set is of mirror image symmetry about a plane and that the fixing of each of the transducers to the ends of the hoop band has a joint for pivoting the transducers into the plane of symmetry which is at a right angle to the plane of the hoop band.
A loudspeaker set comprises three loudspeakers 29, 30 and 31 for use with a PC having a monitor 24. The loudspeaker 31 is stationary and mounted on the monitor 24. The loudspeakers 29 and 30 are mounted on foldable stands 22 and 23 that enable these loudspeakers to be moved and held at either side of a listener's head 28 for use. The stands each consist of three pivotably connected hollow limbs that enable the loudspeakers to move horizontally and vertically with respect to a top of a table 27 into the position shown in the Figure. When not in use, the stands fold up with the limbs in line to store the loudspeakers 29 and 30 at the sides and behind the monitor 24.
Stereo speakers 30 can be disconnected from a crossover headband 10 and clipped onto a variety of headwear in use today, such as a baseball cap, sweatband or sunvisor. A spring-loaded base piece and socket 24 allows the speaker 30 to adjust at an angle perpendicular to the user's ears and rotate 360 degrees laterally to the ear without removing the speakers from the head.
