Abstract:
1. A headset communication unit comprising: a housing having a first pivotal portion that has a pivotal end and connects a supporting pillar in direction of the pivotal end disposed thereon; an ear hook mounted on the housing; and a microphone arm pivotally connected to the first pivotal portion of the housing and rotating between an opening status and a closing status, the microphone arm comprising an upper housing and a lower housing, a containing room formed between the upper housing and the lower housing and containing a microphone and an elastic slice member; wherein in the process of the microphone arm rotating from the opening status to the closing status, the elastic slice member contacts the supporting pillar and rotates around the supporting pillar, among this process, there is a farthest supporting position away from a geometric center of the cross-section of the supporting pillar in all supporting position of the supporting pillar supporting the elastic slice member, when the elastic slice member contacts the farthest supporting position, an elastic force stored in the deformed elastic slice is maximized, the elastic force is released to push the microphone arm forward to the closing status.
