Abstract
A headphone includes a pair of ear cup assemblies attached to a headband. Each ear cup assembly includes a cushion, an earplate, a back plate and an acoustic transducer. These elements snap together and are held together by integral fasteners. Each ear cup assembly is attached to the headband by a ring-shaped yoke which is entrapped between the assembled back plate and ear plate. The result is a durable, lightweight structure which is easy to assemble on a mass production basis.
Claims18
A headphone, the combination comprising:
- an ear plate having acoustic openings distributed in a pattern around a sound emitting axis which passes through the ear plate;
- an acoustic transducer disposed against the back surface of the ear plate and aligned over the acoustic openings;
- first snap action fastening means for fastening the acoustic transducer to the ear plate, said first snap action fastening means having elements which are integrally formed on the ear plate and acoustic transducer;
- a back plate disposed against the back surface of the ear plate to form an ear cup assembly which surrounds the acoustic transducer;
- second snap action fastening means for fastening the back plate to the ear plate, said second snap action fastening means having elements which are integrally formed on the ear plate and back plate;
- a headband for supporting the ear cup assembly over the ear of a listener;
- and
- means for attaching the ear cup assembly to the headband.
5 more elements
A headphone, the combination comprising;
- an ear cup assembly having an ear plate in which acoustic openings are formed in a pattern about a sound emitting axis which extends through the ear plate and which includes a set of fastener openings disposed in a pattern radially outward from the acoustic openings;
- an ear cushion having an annular shaped support disc attached to its back surface;
- and
- a set of latches formed on the back surface of the support disc and aligned to extend through the fastener openings and engage the back surface of the ear plate to fasten the cushion to the ear cup assembly.
1 more element
A headphone, the combination comprising:
- an ear plate having acoustic openings disposed in a pattern around a sound emitting axis and having a flange formed on its periphery to provide a first bearing surface which is directed rearward;
- an acoustic transducer mounted to the back of the ear plate to direct sound through the acoustic openings;
- a back plate fastened to the ear plate to form an ear cup assembly which encloses the acoustic transducer, the back plate including a flange formed on its periphery which defines a second bearing surface which is directed forward toward the first bearing surface and is spaced therefrom to define a channel;
- and
- a yoke for attaching the ear cup assembly to a headband, the yoke having a pair of legs which extend around the periphery of the back plate on opposite sides, each leg having a portion which extends into said channel and is entrapped therein to thereby fasten the yoke to the ear cup assembly.
2 more elements
A headphone, which comprises:
- a headband for extending over the head of a user;
- a yoke having a bracket which connects to one end of the headband and which includes a ring that extends downward from the bracket;
- an ear cup assembly disposed within the ring;
- and
- means for attaching the ear cup assembly to the ring to enable the ear cup assembly to pivot about a horizontal axis,
- wherein the ear cup assembly includes a flange which extends completely around its periphery to present an annular shaped bearing surface, the bearing surface having a first sloped portion which engages the ring at points above the horizontal pivot axis when the ear cup assembly is pivoted in one direction, and a second sloped portion which engages the ring at points below the horizontal pivot axis when the ear cup assembly is pivoted in the other direction.
