In a neckband type headphone device there is provided a band onto which speaker units are connected at both ends thereof. These speaker units are worn on the left and right ears. The band has a shape wherein the area close to the connecting part between both speaker units forms a curve and passes on one of a position above and below the ears of the listener when it is wound in a circular shape and extended. The band is formed from an elastic material into a shape that presses down at the approxi...

An ear-hanging type headphone has an ear hanger arm attached to a rotation shaft portion that is movably mounted on a convex housing of a headphone body at a location that is offset from a central axis of the convex housing by a predetermined eccentric angle. Upon moving the rotation shaft portion relative to the convex housing a distance between the ear hanger arm and a sound emitting side of the headphone is altered to facilitate placing the headphone on the ear. The rotation shaft portion can...

A headphone has a headband and two earpieces each connected to the headband so as to be pivotable relative thereto. When assuming a Cartesian coordinate system having a Z plane that is a symmetry plane of the headphone, having a Y plane that is positioned perpendicularly to the Z plane and extends through a center of the headband, and having an X plane that is positioned perpendicularly to the Z and Y planes at any desired height, a pivot axis is provided between the headband and the earpiece, r...

A headphone comprising: two ear cups; a head band; and coupling means for rotatably coupling the ear cups to the head band, the ear cups having ear pads on those sides facing each other, respectively, the head band being positioned on that side of each of the ear cups away from the side where the ear pad is provided, said coupling means rotatably coupling the head band to that side of each of the ear cups located away from the side where the ear pad is provided, whereby the coupling means enable...

A headphone supported at the ear position for reproducing sound comprising (a) a frame, (b) a cone membrane, (c) at least one opening provided in the frame to connect the space, defined between the front face of the frame and the rear face of the cone membrane, and the free space at the rear part of the frame, (d) a member for applying acoustic resistance to sound which passes through the openings, and (e) a mask member to vary bass reproduction characteristics by varying the area of the opening...

A headphone supported at the ear position for reproducing sound comprises (a) an oscillating member for sound reproduction, (b) a frame to support the oscillating member, (c) at least one opening constituting a path from the space, defined by the inside of the oscillating member, an ear pad and the ear to the free space on the outside of the oscillating member, and (d) an acoustic resistance member disposed in the opening.

The headphone preferably comprises a toroidal seal ring which rests against or surrounds the user's ear and is constituted of a soft, yielding, and preferably elastic material. The seal ring, with the headphone positioned on the head of a user, forms a coupling space between an active diaphragm, actuated by an electroacoustic transducer, and the auditory canal of the user's ear. This coupling space is substantially sealed from the exterior of the headphone, and is formed with at least one openin...

A headphone is composed of a speaker, a microphone, and a flexible earpiece capable of being secured to the external ears of various sizes. The flexible earpiece is formed of a flexible rod which is provided at one end thereof with a female portion and at another end thereof with a male portion engageable with the female portion.

A headphone has an electroacoustic transducing device for converting an electrical signal to an acoustic signal, a housing for housing the electroacoustic transducing device, a flexible support member of which one end is fixed to the housing, and a vibration member disposed at the other end of the flexible support member. The vibration member generates primary vibrations by an electrical signal having a specific correlation to the electrical signal supplied to the electroacoustic transducing dev...

A headphone capable of attaining binaural hearing giving substantially the same sound quality as one would expect from ordinary loudspeakers, said headphone having such sound pressure versus frequency characteristics that there are two peaks between 1.5 and 5 KHz and the level differences between the low level area and the peaks are limited within the range of 6 to 17 dB. The headphone leads the sound from a transducer through the outside as well as inside of the headphone to the ears.
