Low-radiation headphone
First Claim
1. A low-radiation headphone with acoustic irradiation housings associated with the ears of the user, for coupling to accommodating dynamic audio transducers, comprising:
- a acoustic baffle (10) disposed in each housing, and whereby said acoustic baffle (10) is formed in a sound-permeable manner in front of the audio transducers and includes a radiation dissipation zone (11, 12, 20) directed toward the temples of the user, said radiation dissipation zone being provided by a greater thickness of the MU-metal than the one in the remaining sound-permeable area of said acoustic baffle (10), said acoustic baffle (10) being made of a MU-metal sheet and perforated only in the area (17) of the audio transducer, wherein the radiation dissipation zone (20) is integrally formed in the perforated area of the MU-metal sheet.

Abstract
The invention relates to a low-radiation headphone with right and left acoustic irradiation housings corresponding to the ears of the user, with each of the housings having an acoustic baffle (10″) comprising MU-metal and accommodating dynamic audio transducers. The acoustic baffle (10″) is formed in a manner permeable to sound in front of the audio transducers, and has a radiation dissipation zone (20) pointing at the temples of the user. The zone (20) dissipating radiation is provided through a greater density of the MU-metal than in the remaining area of the acoustic baffle (10″) that is permeable to sound. The acoustic baffle (10″) as a whole consists of MU-metal sheet and the audio transducer is perforated in one area (17), but otherwise solid. The radiation dissipation zone (20) is formed in the perforated area of the MU-metal sheet as one piece.
