Abstract

The present disclosure relates to a height adjustment arrangement (100) for an ear cup in a hearing protector unit, wherein the height adjustment arrangement (100) comprises an elongated member (130) and a tubular holding member (110) connected to the elongated member, wherein the holding member provides a substantially hollow interior (111). The height adjustment arrangement further comprises a clamping member (120), wherein the clamping member is arranged to be moved from an unlocked position, in which position relative movement between the elongated member (130) and the holding member (110) is enabled, to a locking position, in which position relative movement between the elongated member and the holding member is prevented. The holding member (110) comprises a first locking member (114), wherein the second end of the holding member is provided with two flanges (115a, 115b) tapering in a direction towards the clamping member, and wherein the first locking member and the flanges are axially separated. The clamping member comprises a hollow interior with a tapering part, which tapers in a direction away from the holding member, and a second locking member, wherein the tapering part and the second locking member are axially separated.

Abstract

A system for forming hearing protectors, an ear cup of such a system and a hearing protector formed from such a system. The system includes a number of first ear cups and a number of second ear cups, the first and second ear cups having noise-reducing spaces of different size, and at least one electronic unit with at least one speaker. This system allows the same type of electronic unit to be used for ear cups with different degrees of noise attenuation.

Abstract

Example embodiments relate to an ear cup for use in a hearing protector unit including two ear cups, and a device to fasten the hearing protector unit to a wearer' s head, the device being connected to the ear cups. The ear cup may include a cup portion with a support surface; and a sealing device, placed against the support surface of the cup portion and intended to bear against a wearer' s head in an area around an ear of the wearer. The sealing device may include a sealing portion of a soft material, which includes a peripherally extending circumference slot and which, in its periphery area, bears against the support surface with an opening of the circumference slot directed towards the cup portion, a sound-attenuating ring, situated in the circumference slot of the sealing portion, and a clamping ring of a rigid material, situated in the circumference slot of the sealing portion to expand the sealing portion produced from soft material, the sealing portion being provided with a peripherally extending flange, introduced in the cup portion such that it bears against an inner side of the cup portion, whereby the clamping ring bears against the flange and presses the flange against the inner side of the cup portion for fastening the sealing device to the cup portion.

Abstract

The invention concerns a system for forming hearing protectors, an ear cup of such a system and a hearing protector formed from such a system. The system comprises a number of first ear cups (5a) and a number of second ear cups (5b), the first and second ear cups having noise-reducing spaces (11 ) of different size, and at least one electronic unit (30) with at least one speaker (31 ). An inner distance (I3) in the noise-reducing space from the speaker (31 ) in the direction away from the noise-reducing space, and a volume (V3) of a resonance space (15) in the first ear cup are adapted to the inner distance (lb) and the volume (Vb) of the resonance space (15) in the second ear cup (5b). This is done in such a manner that, when the electronic unit is mounted in each ear cup, sound emitted by the speaker (31 ) in each ear cup produces substantially the same sound characteristic from the first ear cup (5a) as that from the second ear cup (5b). This allows the same type of electronic unit to be used for ear cups with different degrees of noise attenuation.

Abstract

An ear cup (1) has a cup portion (I' ) with a support surface (3) , as well as a sealing device (4) , which is placed against the support surface of the cup portion for bearing against a wearer' s head in an area around an ear of the wearer. The sealing device (4) comprises a sealing portion (5) of a soft material, which in its periphery area bears against said support surface (3) , and a clamping ring (7) of a hard material, which expands the sealing portion (5) . The sealing portion (5) is provided with a peripherally extending flange, which is introduced in the cup portion (1') and bears against the inner side of the cup portion, whereby the clamping ring (7) bears against the flange and presses the flange against the inner side of the cup portion (1') for fastening the sealing device (4) to the cup portion (I' ).
