Abstract: A headset and/or a hearing protection device comprises a waterproof speaker assembly. The waterproof speaker assembly comprises a speaker unit, a waterproof speaker housing, and a waterproof pressure equalization element. The speaker unit includes a transducer configured to generate an audio frequency signal. The waterproof speaker housing is configured to receive and sealably enclose, in part or in full, the speaker unit in an interior or a cavity of the waterproof speaker housing. The waterproof pressure equalization element is permeable to air. The waterproof speaker housing is configured to receive and/or support the waterproof pressure equalization element. The waterproof pressure equalization element is configured to equalize surrounding or ambient pressure changes from the interior or cavity of the waterproof speaker housing.

Abstract: A cushion configured to be secured to an ear cup of a headset and/or hearing protection device. The cushion defines an inner opening and includes a contact surface along a periphery proximal part of the cushion. The contact surface is configured to abut against and contact a user's head around an ear of the user when the headset and/or hearing protection device is worn by the user. The contact surface of the cushion has a predetermined height profile where respective height values of the predetermined height profile at multiple locations of the contact surface vary about a center or center point of the cushion. The locations are located nearest or towards the inner opening, and a first height of the predetermined height profile is a globally largest height. The first height is located in an upper front-facing part of the cushion.

Abstract: The present invention relates to a headset and/or a hearing protection device (300) comprising a, the waterproof speaker assembly (100) comprising a speaker unit (101) comprising a transducer configured to generate an audio frequency signal, a waterproof speaker housing (103), wherein the waterproof speaker housing (103) is configured to receive and sealable enclose, in part or in full, the speaker unit (101) in an interior or a cavity (107) of the waterproof speaker housing (103), and a waterproof pressure equalization element (105) being permeable to air, wherein the waterproof speaker housing (103) is configured to receive and/or support the waterproof pressure equalization element (105), and the waterproof pressure equalization element (105) is configured to equalize surrounding or ambient pressure changes from the interior or cavity (107) of the waterproof speaker housing (103).

Abstract: A waterproof microphone assembly, which includes a waterproof acoustic transducer converting impinging sound energy into an electrical microphone signal. The assembly includes a wind noise filter suppresses ambient noise and has a first side and a second side. The wind noise filter includes a channel located between and connecting the first side and the second side. The assembly includes a housing having a cavity with a distal end and a proximal end. The distal end is acoustically connected with the acoustic transducer, and the proximal end is adjacent to and/or includes a part of the first side. The wind noise filter absorbs a liquid from at least the channel.

Abstract: The invention relates to an acoustic micro-electrical-mechanical-system (MEMS) transducer formed on a single die based on a semiconductor material and having front and back surface parts opposed to each other. The invention further relates to a method of manufacturing such an acoustic MEMS transducer. The acoustic MEMS transducer comprises a cavity formed in the die to thereby provide a back volume with an upper portion facing an opening of the cavity and a lower portion facing a bottom of the cavity. A back plate and a diaphragm are arranged substantially parallel with an air gap there between and extending at least partly across the opening of the cavity, with the back plate and diaphragm being integrally formed with the front surface part of the die. The bottom of the cavity is bounded by the die. The diaphragm may be arranged above the back plate and at least partly extending across the back plate.
