Hearing device

A hearing device comprising:

• an earmould having a front end, a rear end, and a middle part between the front end and a rear end, the front end comprising a front opening, and the rear end comprising a rear opening, wherein the front end of the earmould is configured to face a tympanic membrane of a user during use, the rear opening being in fluid communication with an outside of an ear canal of the user during use;
• a receiver housing in the earmould, the receiver housing accommodating a receiver, wherein the receiver housing has a first end and a second end opposite from the first end, wherein the front opening of the earmould is closer to the first end of the receiver housing than to the second end of the receiver housing;
• a sound passage extending at least between the front opening of the earmould and the rear end of the earmould;
• an active vent located between the second end of the receiver housing and the front opening of the earmould, wherein when the active vent is in an open state, the active vent allows sound transmission through the sound passage, and wherein when the active vent is in a closed state, the active vent hinders the sound transmission through the sound passage;
• and
• a supporting structure configured to maintain the receiver housing in place with respect to the earmould, wherein the supporting structure is inside the earmould, and includes a fluid opening in fluid communication with the rear opening of the earmould.
