Abstract
Abstract A headset is provided with a mounting member attached to the headband or for mounting on a spectacle frame. The earpiece is in the end of a support member which is pivotally mounted on the mounting member in such a way that it can rotate about two mutually perpendicular axes perpendicular to the longitudinal axis of the support member.

An earphone assembly, comprising a. mounting means adapted for mounting on the head of a user; b. earpiece means including an electro-acoustical transducer; c. earpiece support means connected at one end with said earpiece means; and d. means connecting said support means with said mounting means for pivotal movement through limited arcs about each of two mutually perpendicular axes each normal to the longitudinal axis of said support means.
Claim 2
Dependent Claim
69 words
An earphone assembly, comprising a. mounting means adapted for mounting on the head of a user; b. earpiece means including an electro-acoustical transducer; c. earpiece support means connected at one end with said earpiece means; and d. means connecting said support means with said mounting means for pivotal movement through limited arcs about each of two mutually perpendicular axes each normal to the longitudinal axis of said support means.
Claim 3
Dependent Claim
28 words
Apparatus as defined in claim 1, wherein said connecting means affords a greater frictional resistance to movement of said support means about one pivotal axis than the other.
Claim 4
Dependent Claim
74 words
said mounting means containing a cavity receiving said cylinder, the configuration of said cavity in one plane conforming to the rounded ends of said cylinder to permit limited pivotal movement of said support means through a first arc (B-B), the configuration of said cavity in the plane normal to said one plane conforming with the circular cross-section of said cylinder member to permit limited pivotal movement of said support means through a second arc.
Claim 5
Dependent Claim
74 words
said mounting means containing a cavity receiving said cylinder, the configuration of said cavity in one plane conforming to the rounded ends of said cylinder to permit limited pivotal movement of said support means through a first arc (B-B), the configuration of said cavity in the plane normal to said one plane conforming with the circular cross-section of said cylinder member to permit limited pivotal movement of said support means through a second arc.
