Abstract
An ear-hanging type speakerphone unit that allows users to listen to both sounds from the speaker and sounds from the outside environment, while suppressing leakage of the sounds emanating from the speaker to the outside environment, is provide for. A directional speaker is adjustably held with its speaker face being, for example, approximately 1 to 2 cm. away from the opening of an external auditory miatus, such that an open air space is formed between the speaker face and the opening of the miatus.
Claims20
A three-dimensionally adjustable body set type speaker unit for mounting directly on a user's body or on an apparatus having a varying radius, comprising:
- a mounting member having a speaker hold member, a universal joint portion and a rotatable stay coupled thereon for detachably mounting said unit on a user's body or a mounting apparatus, and a directional speaker positioned on said rotatable stay wherein said speaker may be adjusted three-dimensionally about said stay to a predetermined distance from a user's ear, wherein said speaker hold member securely positions said directional speaker at said predetermined distance away from a user's ear to form an air gap having a predetermined gap space as determined between said ear and a speaker face of said speaker such that said speaker face is not in contact with said user's ear, and said speaker face is relationally adjustable three-dimensionally in a predetermined range to said predetermined distance, wherein when said speaker unit is in use and emanating sound, said speaker face is optimally positioned to suppress sound leakage to an external environment while permitting external sounds from said external environment to be available to a user.
A three-dimensionally adjustable set type speaker set for mounting directly on a user's body or on an apparatus having a varying radius, comprising:
- a mounting member having a speaker hold member, a universal joint portion and a rotatable stay coupled thereon for detachably mounting said unit on a user's body or a mounting apparatus, and at least one directional speaker positioned on said rotatable stay and three-dimensionally rotatable about said stay at a predetermined distance from a user's ear, having a speaker face for assembly with said mounting member wherein each of said speakers is adjustably positionable such that each of the faces may be securely positioned at a predetermined distance away from a user's ear by a speaker hold member when mounted, wherein said speaker hold member, when assembled, securely positions each of said at least one directional speakers at said predetermined distance away from a user's ear to form an air gap having a predetermined gap space as determined as between said ear and said speaker face, wherein said speaker is capable of outputting a received audio signal through via said speaker face,
- and said speaker face is relationally adjustable three-dimensionally in a predetermined range to said predetermined distance, wherein when said speaker unit is in use and emanating sound, said speaker face is optimally positioned to suppress sound leakage to an external environment while permitting external sounds from said external environment to be available to a user.
The assembly of a mounting member detachably mountable on a body portion of a user or on an apparatus having a varying radius, and at least one directional speaker having a speaker face assembled with said mounting member, wherein each of said speakers is three-dimensionally positionable in a predetermined range about a rotatable stay such that each of the faces may be securely positioned at a predetermined distance away from a user's ear by a speaker hold member, a universal joint portion and said rotatable stay coupled thereon when mounted, wherein said speaker hold member, assembled to said mounting member, securely positions said directional speaker at said predetermined distance away from a user's ear to form an air gap having a distance as between said ear and said face, wherein said speaker is capable of outputting a received audio signal through via said face.
