Headset and headphone
There is provided a headset having a head band, at least one fork for receiving an earpiece and a receiving portion between an end of the head band and one of the forks. The fork is arranged pivotably about a pivot axis. The fork has a first end having a support element. The receiving portion has a slider having at least two receiving positions. The support element engages into one of the at least two receiving positions of the slider and thus limits the maximum deflection of the fork about the pivot axis.
1. An earphone or headset comprising at least one earpiece, the earpiece comprising:
at least one electroacoustic reproduction transducer inside the earpiece for generating a useful sound, the electroacoustic reproduction transducer facing the ear canal of a user when the earphone or headset is being worn;
a microphone serving as a microphone for active noise reduction,
wherein the microphone is arranged in front of the electroacoustic reproduction transducer, and
wherein the microphone is configured in the same direction as the electroacoustic reproduction transducer; and
a cover element arranged in front of the electroacoustic reproduction transducer between the microphone and at least a part of the electroacoustic reproduction transducer,
wherein the useful sound generated by the electroacoustic reproduction transducer is at least partially deflected away from the microphone by the cover element so that the microphone detects in particular the interference sound which reaches the ear of a user and to a lesser degree the useful sound generated by the electroacoustic reproduction transducer.
2. An earphone or headset as set forth in claim 1 , wherein the cover element is arranged in a way that the useful sound generated by the electroacoustic reproduction transducer impinges on the microphone with a certain delay.
3. An earphone or headset as set forth in claim 1 , wherein the cover element is in the form of a disk and the disk is larger than the microphone.
4. An earphone or headset as set forth in claim 1 , wherein the area of the cover element is larger than that of the microphone.
5. An earphone or headset as set forth in claim 4 , wherein the ratio of the area of the microphone to the area of the cover element is less than 0.8.
6. An earphone or headset as set forth in claim 4 , wherein the ratio of the area of the microphone to the area of the cover element is 0.25.
7. An earphone or headset as set forth in claim 1 , the earpiece further comprising:
an acoustic wall inside the earpiece for holding the electroacoustic reproduction transducer and the microphone.
8. An earphone or headset as set forth in claim 7 , the earpiece further comprising:
a plurality of spokes between the electroacoustic reproduction transducer and the acoustic wall.
9. An earphone or headset as set forth in claim 1 , wherein the earpiece has a receiving portion for receiving the microphone, wherein the microphone is fixed in the receiving portion by means of a capsule mounting, wherein the capsule mounting has an elastic material so that the microphone is provided in the receiving unit in structure-borne sound-decoupled relationship.
