Headphone device
View Patent ↗[Problem] To provide a headphone device that outputs an audio signal output from a playback device, such that the headphone device has a more compact housing while being capable of highly sensitive acoustic output of an audio signal having high sound quality, and is capable of consuming less power during highly sensitive acoustic output of an audio signal having high sound quality. [Solution] In a headphone device that outputs an input audio signal, the headphone device is provided with: a housing shaped with a hollow interior, said housing being provided with a projection on the front thereof, said projection being provided with a hole passing therethrough in the front-to-back direction; and a first driver unit and second driver unit each affixed to the inner wall of the housing, and each having a diaphragm that acoustically outputs the input audio signal. The first driver unit and the second driver unit have been given a parallel arrangement, such that the diaphragms thereof are in mutual opposition.
1. A headphone device for outputting an input audio signal, comprising:
a first housing and a second housing, the first housing and second housing each forming a hemispherical shape, the first and second housing together forming a combined housing having a generally spherical shape with a cavity formed therein by overlapping edges of the first housing and second housing, the combined housing comprising a protrusion at a front thereof, the protrusion having a through hole in a fore-and-aft direction; and
a first driver unit being fixed to an inner wall of the first housing and a second driver unit fixed to an inner wall of the second housing, the first and second driver unit each comprising a diaphragm for emitting an input audio signal,
wherein the first driver unit and the second driver unit are arranged in parallel with each other so that the diaphragms thereof are opposed to each other.
2. A headphone device for outputting an input audio signal, comprising:
a first housing and a second housing, the first housing and second housing each forming a hemispherical shape, the first and second housing together forming a combined housing having a generally spherical shape with a cavity formed therein by overlapping edges of the first housing and second housing, the combined housing comprising a protrusion at a front thereof, the protrusion having a through hole in a fore-and-aft direction; and
a first driver unit fixed to an inner wall of the first housing and a second driver unit fixed to an inner wall of the second housing, the first and second driver unit each comprising a diaphragm for emitting an input audio signal,
wherein the first driver unit and the second driver unit are arranged so that the diaphragms thereof are opposed to each other and the diaphragms are slanted by a predetermined angle.
3. A headphone device according to claim 1 , wherein a distance from the diaphragm of the first driver unit to the diaphragm of the second driver unit is approximately 2 mm.
4. A headphone device according to claim 1 , wherein the through hole is provided at a position which is substantially perpendicular to the first driver unit and the second driver unit.
5. A headphone device according to claim 2 , wherein a distance from the diaphragm of the first driver unit to the diaphragm of the second driver unit is approximately 2 mm.
6. A headphone device according to claim 2 , wherein the through hole is provided at a position which is substantially perpendicular to the first driver unit and the second driver unit.
7. A headphone device according to claim 1 , wherein the first housing and the second housing are symmetrical in shape.
8. A headphone device according to claim 2 , wherein the first housing and the second housing are symmetrical in shape.
9. A headphone device for outputting an input audio signal, comprising:
a first housing and a second housing, the first housing and second housing each forming a hemispherical shape, the first and second housing together forming a combined housing having a generally spherical shape with a cavity formed therein by overlapping edges of the first housing and second housing, the combined housing comprising a protrusion at a front thereof, the protrusion having a through hole in a fore-and-aft direction; and
a first driver unit fixed to an inner wall of the first housing and a second driver unit fixed to an inner wall of the second housing, the first and second driver unit each comprising a diaphragm for emitting an input audio signal,
wherein (1) the first driver unit and the second driver unit are arranged in parallel with each other so that the diaphragms thereof are opposed to each other, or (2) the first driver unit and the second driver unit are arranged so that the diaphragms thereof are opposed to each other and the diaphragms are slanted by a predetermined angle, and
wherein the diaphragm of the first driver unit is disposed at a distance away from the diaphragm of the second driver unit such that the distance provides an increased sound pressure of an audio signal emitted from the headphone device.
10. A headphone device according to claim 9 , wherein the distance from the diaphragm of the first driver unit to the diaphragm of the second driver unit is approximately 2 mm.
