On-the-ear ear cushion with multiple foams having different properties
Disclosed is a headset, an earphone and an ear cushion for attenuating audio noise by acoustic sealing of the ear. The ear cushion is configured to be arranged on an earphone. The ear cushion is configured to be arranged on the ear of a user when the user is wearing the earphone in its intended position. The ear cushion comprises a first foam having first properties. The ear cushion comprises a second foam having second properties. The second foam is at least partly surrounding the first foam. The second foam is configured to at least partly adjoin/abut at least a part of the user's ear. The first properties and the second properties are different.
1 . An ear cushion for attenuating audio noise by acoustic sealing of the ear, the ear cushion is configured to be on an earphone and rest on the ear of a user when the user is wearing the earphone in its intended position, and the ear cushion comprising:
a first foam having first properties; and
a second foam having second properties;
wherein the second foam is at least partly surrounding the first foam,
wherein the second foam is configured to at least partly adjoin or abut at least a part of the user's ear so that the ear cushion rests on the user's ear,
wherein the first properties and the second properties are different,
wherein the first properties and the second properties are hardness,
wherein the first foam has a first hardness value,
wherein the second foam has a second hardness value, and
wherein the second hardness value is in the range of about 15-30 Asker F and the first hardness value is in the range of about 3-15 Asker F.
2 . The ear cushion according to claim 1 , wherein the second foam is at least partly surrounding the first foam in a first plane parallel to at least one of the ear or the head of the user.
3 . The ear cushion according to claim 1 , wherein the first foam and the second foam are concentric to each other.
4 . The ear cushion according to claim 1 ,
wherein the first foam has an outer circumference,
wherein the second foam has an inner circumference, and
wherein the outer circumference of the first foam abuts the inner circumference of the second foam.
5 . The ear cushion according to claim 1 , wherein the ear cushion has a first length in a first direction of between about 4 cm to about 8.5 cm, and a second length in a second direction of between about 4 cm to about 8.5 cm.
6 . The ear cushion according to claim 1 ,
wherein the ear cushion is configured to cover at least one of the ear canal, at least a part of a concha, at least a part of a tragus, at least a part of an anti-tragus, or at least a part of an anti-helix of the ear, and
wherein the ear cushion is configured to expose at least a part of at least one of the helix or a part of an ear lobe.
7 . The ear cushion according to claim 1 , wherein the first properties and the second properties are one or more of thickness, memory, or density.
8 . The ear cushion according to claim 1 ,
wherein the first foam is configured to adapt to the shape of the ear thereby providing an acoustic seal by at least one of reducing or preventing leaks between the first foam and the user's ear,
wherein the first foam is configured to provide attenuation of first frequencies of sound, and
wherein the first frequencies are frequencies above a value F.
9 . The ear cushion according to claim 1 ,
wherein the second foam is configured to prevent at least one of air or sound to pass through the second foam,
wherein the second foam is configured to provide attenuation of second frequencies of sound, and
wherein the second frequencies are frequencies below a value F.
10 . A headset comprising at least one earphone having an ear cushion according to claim 1 .
