Abstract: A headphone device includes first and second head band members, a first fulcrum portion for pivotally supporting top ends of the first and second head band members so that the lower ends of the first and second head band members are moved towards and away from each other, first and second speaker unit supporting members carrying first and second speaker units, and second and third fulcrum portions for pivotally supporting the respective ends of the first and second speaker unit supporting members for rotation towards the lower ends of the first and second head band members. The center axes of rotation of the second and third fulcrum portions extend in a direction substantially perpendicular to the center axis of rotation of the first fulcrum portion. The headphone device also includes ear support portions provided on the first and second speaker unit supporting members that are retained between the head and the auricles of the user when the user attaches the headphone device to the head.

Abstract: An aircraft headset includes a headset band, including a head element and a pair of ear cup supports slidably received in the head element, ear cups pivotally attached at one end of each ear cup support; and a microphone boom pivotally attached to one of the ear cups; an improved ear cup tensioning mechanism including a tongue extending laterally from each end of the headset band and a conformal tongue receiver located adjacent the other end of each ear cup support; wherein the tongue receiver is conformal with the tongue, and wherein the tongue and the tongue receiver are constructed and arranged to provide near-constant lateral pressure between the ear cups and a wearer's head.

Abstract: A headphone based compact disk player is designed to be worn on a user's head in normal fashion and to play a compact disk received within the device through speakers located within the device. The headphone based compact disk player has a first housing having a first speaker therein and a second housing also having a second speaker therein. A bridge connects the two housings. A playing mechanism receives the compact disk through an opening on the first housing and plays the audio track recorded on the compact disk through the speakers. Appropriate control mechanisms are located on the device.

Abstract: A head-phone having a case member storing therein a headphone unit, wherein a coating film containing a light discolor pigment to be discolored by irradiation of sun light is provided on the whole surface or a predetermined surface of the case member.

Abstract: The invention relates to a headset (1) for a hearing protector provided with a padding part (12) having an essentially elliptical ear opening (18). The headset comprises a microphone (2), an earphone (3), and conducting wires (7) for bringing signals to the earphone (3) and from the microphone (2). According to the invention the earphone (3) is attached to a bow part (10) whose contour essentially follows the external dimensions of the hearing protector padding (12), and a mounting wing (13, 4) is connected to the bow part (10) or the earphone (3) and has a maximum dimension (A) which is smaller than the maximum dimension of the ear opening (18) and yet greater than the minimum dimension (B) of the ear opening (18), and during use the maximum dimension of the mounting wing (13, 4) is essentially horizontal.
