Headset having right- and left-ear sound output units with through-holes formed therein
Provided is a portable telephone or an earphone or an electromagnetic-type vibration unit that comprises an electromagnetic-type vibrator including two mutually relatively moving portions supported via an elastic body, and that is configured to produce vibrations from at least one of the two portions for cartilage conduction. The elastic body provides a cartilage conduction portion to be contacted with the ear cartilage. The elastic body is disposed on or in the vicinity of an upper corner portion of a housing. One of the two portions is supported on a housing structure with the elastic body supported by the housing structure, and the other of the two portions is supported by the elastic body. Of the two portions, one with a greater weight is supported by the elastic body. Of the two portions, one or a portion connected thereto provides a cartilage conduction portion to be contacted with the ear cartilage, with the elastic body disposed between the two portions. From both of the two portions, vibrations to be conducted to the elastic body are obtained.
1. A headset, comprising: a local communication unit which performs wireless communication within a local area; right- and left-ear sound output units which output sound received by the local communication unit and which have right- and left-ear cartilage conduction units respectively; and a sound microphone which collects sound to be transmitted from the local communication unit, wherein,
when the right- and left-ear sound output units are worn on right and left ears respectively, the right- and left-ear cartilage conduction units make contact with right- and left-ear cartilage so as not to prevent outside sound from entering right and left external auditory meatus so that directions from which the outside sound comes can be recognized with both ears as when they are not worn,
the right- and left-ear cartilage conduction units, when worn, make contact with tragi respectively, the right- and left-ear cartilage conduction units having concavities which, when they are worn, make contact with the tragi while preventing the tragi from bending so as to close entrances of the external auditory meatus respectively, the right- and left-ear cartilage conduction units having through-holes away from the concavities so as not to prevent outside sound from entering the right- and left-ear external auditory meatus.
2. The headset according to claim 1 , wherein the right- and left-ear cartilage conduction units have shapes that fit in right- and left-ear cava conchae respectively from in front of a face.
3. The headset according to claim 1 , wherein the right- and left-ear cartilage conduction units are formed of elastic bodies respectively.
4. The headset according to claim 3 , wherein the right- and left-ear cartilage conduction units have cartilage conduction vibration sources respectively.
5. The headset according to claim 4 , further comprising: an arm part which supports the right- and left-ear cartilage conduction units without making contact with the cartilage conduction vibration sources and which has an acoustic impedance different from that of the right- and left-ear cartilage conduction units.
6. The headset according to claim 5 , wherein the sound microphone is supported on the arm part.
7. The headset according to claim 5 , further comprising: right and left outside noise detection microphones which are supported on the arm part.
8. The headset according to claim 7 , wherein the sound collected by the right and left outside noise detection microphones is fed to the right- and left-ear cartilage conduction units respectively so as to cancel external noise inside the right and left external auditory meatus.
9. The headset according to claim 8 , wherein of the sound collected by the right and left outside noise detection microphones, a sound component that exhibits a difference between them is not fed to the right- and left-ear cartilage conduction units so as not to be canceled in the right and left external auditory meatus.
10. The headset according to claim 1 , wherein sounds received by the local communication unit from a plurality of other headsets are mixed with a different right ear sound-to-left ear sound balance for each headset, and the mixed sounds are transmitted by the local communication unit to the plurality of other headsets.
11. A headset, comprising: a local communication unit which performs wireless communication within a local area; right- and left-ear sound output units which output sound received by the local communication unit and which have right- and left-ear cartilage conduction units respectively; and a sound microphone which collects sound to be transmitted from the local communication unit, wherein,
when the right- and left-ear sound output units are worn on right and left ears respectively, the right- and left-ear cartilage conduction units make contact with right- and left-ear cartilage so as not to prevent outside sound from entering right and left external auditory meatus so that directions from which the outside sound comes can be recognized with both ears as when they are not worn, and
the right- and left-ear cartilage conduction units have through-holes so as not to prevent outside sound from entering the right- and left-ear external auditory meatus.
12. A headset, comprising: a local communication unit which performs wireless communication within a local area; right- and left-ear sound output units which output sound received by the local communication unit; and a sound microphone which collects sound to be transmitted from the local communication unit, wherein
the right- and left-ear sound output units have through-holes so as not to prevent outside sound from entering the right- and left-ear external auditory meatus, and
the right- and left-ear sound output units, when worn on right and left ears respectively, do not prevent outside sound from entering right and left external auditory meatus so that directions from which the outside sound comes can be recognized with both ears as when they are not worn.
