Abstract (en)
[origin: WO8909524A1] An ergonomic telephone handset (10, 30, 40, 50, 62, 70) having a body comprising a speaker portion (13, 14, 23, 24, 33, 42, 51, 61, 72, 76), a microphone portion (11, 31, 41, 52, 63, 71) and handle portion joining said speaker and microphone portions wherein the speaker portion includes an ear engaging portion which is pivotably (16, 26, 32, 34, 37, 44, 54, 73) or flexibly supported (13, 17, 22, 38, 43, 53, 60, 76) relative to said handle portion such that in use, the speaker portion is maintained substantially aligned with a user's ear irrespective of the location of the hand piece. The speaker portion may be mounted upon a pivotal joint (26, 36, 37, 32, 73) or universal joint (54). The ear piece may be made of flexible foam like material (13, 19, 22, 43, 53, 60, 76) to provide said flexing support to comfortably contact the ear of a user so that the ear piece remains aligned with the ear independent of any movement of the handle portion. The body portion may be encased with a tough plastic mesh material (74) which in turn is coated with soft plastic material forming a totally enclosing outer shell (75) over the body portion of the handset. The ear piece (15) may incorporate a cheek bone rest portion (12).
