    • An ear hook personal sound device is disclosed. The key point of the technical solution of the disclosure lies in including a housing, a speaker and a front conduction tube. One surface of the speaker is connected and sealed with the front conduction tube, a radiation port is formed on the speaker, and a distance for a sound wave radiated by the speaker to be conducted through the front conduction tube to an opening of an ear canal is less than 10 mm. The other surface of the speaker is hermetically connected with a rear conduction tube, a sound wave radiated by the other surface of the speaker is conducted to a back of an ear through the rear conduction tube, and a shortest conduction distance for a sound wave at an orifice of the rear conduction tube to be conducted to the opening of the ear canal is no less than 40 mm. According to the disclosure, the ear canal is unblocked, such that it is convenient for a user to hear ambient sound. Rich bass is realized, and the speaker is additionally provided with the conduction tubes, which will not increase a resonance frequency of the speaker like the addition of a box to the speaker, and instead will decrease the resonance frequency, thereby improving a low-frequency effect of the speaker.

    • Provided is a hearing device comprising an earmould (3). The earmould comprises a front end (5), a rear end (7) opposite the front end, and a middle part (8) arranged in-between the front and a rear end. The front end comprises a front opening (9), and the rear end comprises a rear opening. The earmould is configured for the front end to be positioned facing a tympanic membrane of the user during use. The hearing device further comprises a receiver housing (25) arranged at least partly within the earmould, where the receiver housing comprises a receiver (11). The receiver housing (25) being positioned with a first end towards the front end (5) of the earmould and a second, opposite, end towards the rear end (7) of the earmould (3). Further, the hearing device comprises a sound passage extending between the front opening (9) and the rear end (7), and configured to allow for fluid connection between the front opening (9) and an outside of the ear canal of the user during use. An active vent (13) comprised in the hearing device comprises a valve positioned in a space within the earmould limited by the second end of the receiver housing and by the front opening (9), and the valve forms at least a part of the sound passage,. The active vent is configured to have an open state and a closed state, wherein the valve, in the open state, provides a fluid connection through the sound passage, wherein the valve, in the closed state, hinders fluid connection through the sound passage. The hearing device further comprises a supporting structure (29) configured to hold the receiver housing (25) in place within the earmould.
