Headphones or earphones are commonly known as electro-acoustic transducers used by a single listener. The invention relates to combing insert and non-insert electro-acoustic transducers in a headphone element. In this way a combination of a wide-low frequency reproduction (insert type) and a wide-high frequency reproduction (non-insert type) are obtained.

The invention relates to headphones. Such headphones always comprise at least one, preferably two, earpieces which are each equipped with a reproduction transducer. Furthermore, appropriate earpieces also comprise an ear cushion, which either encloses the user's ear when the headphones are put on or lies on the ear. The object of the present invention is to solve the problems of prior art arrangements and find a simple embodiment for the headphones. Headphones having at least one headphones earp...

In order to provide headphones with a cord-winding mechanism capable of favorably retracting and winding a cord, a cord-winding mechanism is incorporated in either or both of the casings of housings 1L and 1R constituting headphones; and a lock is released by joining the left and right casings together, so that the cord is retracted and wound.

A headphone has a headband and two earpieces each connected to the headband so as to be pivotable about at least two pivot axes. The two pivot axes intersect one another at a point of intersection that is positioned on or near a central axis of the earpiece, respectively. Arms connect the earpieces to the headband, wherein the arms define a first one of the two pivot axes, respectively. A second one of the two pivot axes is fixedly arranged on the headband, respectively. In this way, the earpiec...

In order to obtain an ear-hook headphone that is light and comfortable to wear, a supporting portion that supports a housing portion is provided in the vicinity of one end of an approximately U-shaped bend of an arm-shaped guide portion; a pushing portion that resiliently pushes from behind the auricle of a user toward the housing portion is provided in the vicinity of the other end; and a sound-outputting surface of the housing portion is disposed on the face side of the listener wearing the he...

An electrostatic headphone speaker assembly includes a push-pull electrostatic driver operated off a coupling transformer, with the transformer secondary also supplying a polarizing circuit for the driver diaphragm. For enhanced operation there is a large resistance in the polarizing circuit to provide a long time constant, and the transformer leakage inductance is resonated with the driver input capacitance at 13 kHz.; and for a stereo headphone set with two transformers provided with ground ju...

A wireless headphone in which an infra-red light signal transmitted from a transmitting apparatus is received and reproduced as an audible sound by a headphone unit portion. A first light receiving element is provided on a top portion of a head band portion of the headphone so that, when a listener wears the wireless headphone, a light receiving surface included in the first light receiving element is directed rearward. Second and third light receiving elements are provided on the pair of headph...

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 member...

An inner-ear type headphone apparatus includes a diaphragm, a driving portion, a backside wall, and a sealed wall plane. A diaphragm backside space is formed between the diaphragm and the driving portion. The driving portion drives the diaphragm. A back cavity communicates with a diaphragm backside space. The back cavity is formed between the driving portion and the backside wall. There is a sound-absorbing space between the backside wall and the sealed wall plane. The backside wall is provided ...

A signal processing circuit for performing predetermined signal processes to input audio signals of four channels, headphones to which an output signal of the signal processing circuit is supplied, and detecting method for detecting a rotation of the head of the listener are provided. Digital filters for convoluting impulse responses obtained by converting head portion transfer functions from sound sources to the right and left ears into time regions to the input audio signals of four channels, ...
