Problems solved by technology

[0002] It has been proposed to add cold retaining material such as phase change element spheres to the composition of earmuffs adjoining the ear or head, but the result is a severe loss of comfort as the material adjoining the head or ear will tend to become Rather rigid and lacks the ability to adjust to the individual shape of the user's head and ears
Also, once the phase change material has all reached high temperatures, heat buildup will continue, at which point the user will have no remedial action

Embodiment Construction

[0023] figure 1 The ear appliance is shown in . The ear appliance comprises a headphone 1 with earmuffs 2 and a removable protector 5, which is connected to a soft cushion 4, and the removable protector 5 is adapted to cover the soft cushion and cover the earmuff 2. at least partly. The replaceable protector 5 comprises at least one layer 6, 7, 8 of material having a compound capable of phase change from liquid to solid, the compound being adapted to change phase in a predetermined temperature range. The foregoing temperature ranges are selected to match the typical temperature of the ears and the skin 22 surrounding the ears of a typical user of a headset.

[0024] A loudspeaker 9 can be placed in the center of the earmuff 2, so that sound can be transmitted from the loudspeaker 9 to the ear. The cushion 4 is provided as a torus with a centrally arranged hole 20 enabling sound to pass from the speaker 9 to the ear. The upholstery 4 comprises an outer layer, such as leathe...

Abstract

An ear appliance is provided which comprises a headphone (1) having a cup (2) which is coupled to soft padding (4), and a protector (5) which is adapted to cover the soft padding (4) and at least a part of the cup (2). The protector (5) comprise at least one material layer (6,7,8) with a compound in said layer having a phase change ability said compound being adapted to change phase at a predetermined temperature range.

Description

technical field [0001] The present invention relates to an ear appliance that abuts the outer ear or the head near the outer ear and feeds sound into the ear and / or blocks external noise from reaching the ear. When an element also includes a microphone for capturing the user's voice, it may be referred to as a headset. Ear kits thus include earmuffs or muffs typically used for the aforementioned devices. When worn continuously for a long time, heat builds up between the user's head and the earmuffs, which causes discomfort to the user. Background technique [0002] It has been proposed to add cold retaining material such as phase change element spheres to the composition of earmuffs adjoining the ear or head, but the result is a severe loss of comfort as the material adjoining the head or ear will tend to become Rather stiff and lacking the ability to adjust to the individual shape of the user's head and ears. Additionally, once the phase change material has all reached h...
