Abstract
A personal hearing device with an outer housing and a sound path with a length of 1-24 mm, a diameter of 0.5-6 mm, a roll of frequency of at least 500 Hz and with a valve configured to open and close the sound path. The sound path has suitable acoustical properties to act as a sound passage for open/closed hearing aids or hearables. The valve is selected to have a small influence on the acoustical properties of the remaining portions of the sound path.
Claims18
A personal hearing device comprising:
- an outer housing,
- a sound path in the outer housing, the sound path extending through the outer housing from a first opening to a second opening,
- a valve including a closing element configured to be sequentially in two positions, where, in a first of the two positions, the closing element leaves open the first opening, the second opening, and the sound path, and, in a second of the two positions, the closing element blocks one or more of the group consisting of the first opening, the second opening, and the sound path,
- where:
- the sound path has a length of 1-12 mm and a cross section of 0.28-10 mm2 and a roll off frequency of at least 500 Hz, and
- the valve includes an actuator for driving the closing element between the first and second positions, at least a portion of the actuator being positioned outside of the sound path.
A valve for a personal hearing device having an outer housing, a sound path in the outer housing, the sound path extending through the outer housing from a first opening to a second opening, the valve being configured to open and close one or more of the group consisting of the first opening, the second opening, and the sound path, the sound path having a length of 1-24 mm, a cross section of 0.28-19.6 mm2, and a roll off frequency of at least 500 Hz, the valve comprising:
- a closing element configured to be sequentially in two positions, where, in a first position, the closing element leaves the first opening, the second opening and the sound path, open and, in the second position, the closing element blocks one or more of the group consisting of the first opening, the second opening and/or the sound path.
