Stereo microphone device

摘要

There is provided an external stereo microphone device that enables further enhancement of operational feeling achieved when microphones are reoriented.;An external microphone attached to a mobile electronic device includes a pair of symmetrically-positioned microphones 60, a holder unit 40 having a pair of holders 46 symmetrically positioned so as to accommodate the pair of microphones 60 respectively and a joint 48 for joining the pair of holders 46 together, a case 14 having a substantially-cylindrical portion 20 that rotatably supports the holder unit 40 and a body 18 that accommodates a circuit board 22, and a roller 56 that revolves over an inner circumferential surface of the cylindrical portion 20 in association with rotation of the holder unit 40.

主权项

1. An external stereo microphone device attached to a mobile electronic device, comprising:
a pair of symmetrically-positioned microphones; a holder unit including a pair of holders symmetrically positioned in order to accommodate the pair of microphones respectively and a joint that joins the pair of holders together; a shaft coupled to the joint; a groove formed on an interior surface of the joint; a presser holding the shaft in a state where the shaft is disposed within the groove; a substantially-cylindrical case that rotatably supports the holder unit; and a revolving body that rotates while the shaft coupled to the joint serves as an axis of the rotation, that is made of an elastic material, that gets out of one or more stopper grooves formed in an inner circumferential surface of the cylindrical case, and that elastically deforms and revolves over the inner circumferential surface of the cylindrical case while experiencing pressure from the inner circumferential surface of the cylindrical case in association with rotation of the holder unit with respect to the cylindrical case.
