There is provided a headset having a head band, at least one fork for receiving an earpiece and a receiving portion between an end of the head band and one of the forks. The fork is arranged pivotably about a pivot axis. The fork has a first end having a support element. The receiving portion has a slider having at least two receiving positions. The support element engages into one of the at least two receiving positions of the slider and thus limits the maximum deflection of the fork about the pivot axis.

Headset and headphone

An earphone, a headset, and an ear pad for an earphone. The ear pad may having the sealing integrity guaranteed. The headset may have portions with different degrees of softness or firmness.

Earphone, headset and ear pad

There is thus provided an earphone comprising a housing () for receiving an electroacoustic transducer, and an ear cushion unit () having an ear cushion material () and a first ring (). The housing has a sealing ring () and a latching unit (). The first ring () has a prestressing when it is placed on the sealing ring () and held by means of the latching unit ().

Earphone and headset

There is provided an earphone comprising a hoop band () for receiving at least one ear pad (OM). The hoop band () has at least two hoop band portions (), wherein at least two of the hoop band portions () are rotatably connected together by way of a rotary joint unit (). In addition in the region of the rotary joint unit the hoop band has a spring unit () which couples the two hoop band portions together and thus exerts a spring force on the hoop band portions (), wherein the spring force is adjustable by adaptation of the coupling by way of a coupling means.

There is thus provided an earphone having a hoop band () for receiving at least one electroacoustic reproduction transducer. The hoop band has at least two hoop band portions () which respectively include an angle, wherein at least two of the hoop band portions () are rotatably connected together. The hoop band also has at least one adjusting unit () for adjusting and fixing the angle, wherein the adjusting unit is coupled to the first and second hoop band portions ().

An actuating device for a brake unit of a vehicle EBS includes a tappet positioned in a housing of the brake unit for actuating a piston to operate a brake valve. A displacement sensor slide measures axial movement of the tappet. So that moving parts of the actuating device are guided with minimal friction and that torque acting on the tappet is compensated for, the tappet includes a base plate disposed non-rotatably in a receiver of a guide ring having spaced-apart oblong holes, a spacer ring disposed in the guide ring having angled edges which extend into the oblong holes, and a window on the guide ring protruding radially outwardly into a slit on the housing to receive the displacement sensor slide.

An actuating device for a brake unit of a vehicle EBS includes a tappet positioned in a housing of the brake unit for actuating a piston to operate a brake valve. A displacement sensor slide measures axial movement of the tappet. So that moving parts of the actuating device are guided with minimal friction and that torque acting on the tappet is compensated for, the tappet includes a cylindrical attachment having a bottom with holes and a shell, a groove on the outer surface of the shell having openings, a spacer ring in the cylindrical attachment between the tappet and the piston having projections which extend into the holes, a guide ring in the groove having raised portions on its inner surface which extend into the openings and a window on its outer surface protruding through an opening into a slit on the housing to receive the displacement sensor slide.
