Abstract

[Problem] To provide a headphone device that is equipped with an ear pad to be inserted into an ear, is electrically connected to a player device via a cable and outputs an audio signal which is output from the player device, with which it is possible to improve in-ear wearability and prevent a pain from being caused inside the ear. [Solution] The headphone device is equipped with: a driver unit that is fixed to a housing and has a diaphragm for emitting a sound of an audio signal; and a nozzle section that is fixed to the housing at one end, holds an ear pad at the other end, has a hollow interior, and is formed so as to slope from the part where the nozzle is fixed to the housing toward the tip of the nozzle section at a predetermined angle with respect to the housing.

Claims (13)

1. A headphone device for outputting an audio signal input to an input terminal through a cable, the headphone device comprising: a driver unit fixed to a housing, the driver unit comprising a diaphragm for emitting the audio signal as sound; and a nozzle section having one end fixed to the housing, another end holding an ear pad, and a hollow interior, the nozzle section being formed so as to be inclined by a predetermined angle with respect to the housing in a region from a portion of the nozzle section fixed to the housing toward a distal end portion of the nozzle section, the nozzle section comprising an outwardly curved portion formed at an intermediate portion of a first side surface of the nozzle section so as to swell outwardly, and an inwardly curved portion formed at an intermediate portion of a second side surface of the nozzle section so as to swell inwardly, the first side surface opposing the second side surface.

2. A headphone device according to claim 1 , wherein when the headphone device is positioned within an ear, the ear pad is configured and arranged to be disposed within an ear canal entrance, and the outwardly curved portion is configured and arranged to be disposed proximal to a swelling portion of the ear canal entrance.

3. A headphone device according to claim 2 , wherein when the headphone device is positioned within an ear, a surface of the outwardly curved portion abuts on the swelling portion of the ear canal entrance.

4. A headphone device according to claim 1 , wherein when the headphone device is positioned within an ear, the ear pad is configured and arranged to be disposed within an ear canal entrance, and the inwardly curved portion is configured and arranged to be disposed proximal to a swelling portion of a tragus of the ear.

5. A headphone device according to claim 4 , wherein when the headphone device is positioned within an ear, the inwardly curved portion is configured and arranged to not press the swelling portion of the tragus of the ear.

6. A headphone device according to claim 1 , further comprising a wing-like plate portion formed of a thin plate and arranged above the housing.

7. A headphone device according to claim 1 , wherein when the headphone device is positioned within an ear, the ear pad is configured and arranged to be disposed within an ear canal entrance, the outwardly curved portion is configured and arranged to be disposed proximal to a swelling portion of the ear canal entrance, and the inwardly curved portion is configured and arranged to be disposed proximal to a swelling portion of a tragus of the ear.

8. A headphone device for outputting an audio signal input to an input terminal through a cable, the headphone device comprising: a driver unit fixed to a housing, the driver unit comprising a diaphragm for emitting the audio signal as sound; and a nozzle section having one end fixed to the housing, another end holding an ear pad, and a hollow interior, the nozzle section being formed so as to be inclined by a predetermined angle with respect to the housing in a region from a portion of the nozzle section fixed to the housing toward a distal end portion of the nozzle section, the nozzle section comprising an outwardly curved portion formed at an intermediate portion of one side surface of the nozzle section so as to swell outwardly,

wherein when the headphone device is positioned within an ear, the ear pad is configured and arranged to be disposed within an ear canal entrance, and a surface of the outwardly curved portion is configured and arranged to abut a swelling portion of the ear canal entrance.

9. A headphone device according to claim 8 , further comprising a wing-like plate portion formed of a thin plate and arranged above the housing.

10. A headphone device for outputting an audio signal input to an input terminal through a cable, the headphone device comprising: a driver unit fixed to a housing, the driver unit comprising a diaphragm for emitting the audio signal as sound; and a nozzle section having one end fixed to the housing, another end holding an ear pad, and a hollow interior, the nozzle section being formed so as to be inclined by a predetermined angle with respect to the housing in a region from a portion of the nozzle section fixed to the housing toward a distal end portion of the nozzle section, the nozzle section comprising an inwardly curved portion formed at an intermediate portion of one side surface of the nozzle section so as to swell inwardly,

wherein when the headphone device is positioned within an ear, the ear pad is configured and arranged to be disposed within an ear canal entrance, and the inwardly curved portion is configured and arranged to not press a swelling portion of the tragus of the ear.

11. A headphone device according to claim 10 , further comprising a wing-like plate portion formed of a thin plate and arranged above the housing.
