- The current invention relates to a hearing device according to the pre-characterising part of
claim 1 and a microphone protection cover for the hearing device. - Hearing devices are known for example from
WO 2009/138524 . The hearing device comprises a housing with two microphones arranged within the housing. A protection cover arranged over each microphone prevents the direct connection of the microphones to the environment. - It is an object of the current invention to provide a hearing device with an improved microphone protection.
This object is realised by a hearing device with the features ofclaim 1. Further embodiments of the hearing device as well as of a microphone protection cover are defined by features of further claims. - A hearing device according to the current invention comprises a housing, at least one microphone arranged within the housing, at least one microphone opening, that connects the respective microphone to the outside of the housing by means of a channel, a first microphone protection cover that is arranged within the housing between the microphone and the microphone opening, and a toggle that is arranged on the first microphone protection cover. The first microphone protection cover comprises at least one protection section adapted to cover at least a part of the respective microphone and a central sealing section adapted to seal the inside of the housing in the region of the toggle. The at least one protection section and the central sealing section are formed integrally in one piece from a single material. A single material can mean one single material only or can mean a material with the same material composition everywhere. A base material with evenly distributed particles therein is also considered a single material. With such a design, less parts are required and the sealing is better.
- In a further embodiment, the first microphone protection cover comprises at least one peripheral sealing section that surrounds the respective protection section. The peripheral sealing sections make sure that no dust, dirt or humidity can enter the inside of the housing sideways from the channel or in the region of the toggle.
- According to another embodiment, the first microphone protection cover has a plate-shaped body whose lateral extension is several times its thickness. The thickness of the at least one protection section is smaller than the thickness of the body. The smaller thickness results in a lesser stiffness.
- In an embodiment, the central sealing section and the at least one peripheral sealing section project beyond the plate-shaped body of the first microphone protection cover. The greater thickness results in a greater stiffness in the sealing area.
- In a further embodiment, the at least one protection section comprises at least one hole. Having a hole reduces the dampening of a sound signal passing through the protection section. The protection section may have a diameter in the range of 1 mm to 3 mm. The hole is dimensioned as such that sound can pass easily and dust, dirt or humidity is prevented from passing, at least partially. The shape of a hole can be circular, oval, square or rectangular. The hole may form a conically expanding volume with a changing diameter.
- In yet another embodiment, the at least one protection section comprises several holes that are arranged in an orderly manner. The holes can be arranged in a linear or circular pattern. This allows for an optimised sound transmittal through a protection section, as the sound can be directed by means of the specially arranged holes. At the sound entrance side of the protection section the diameter of the holes should be smaller than at the sound exit side. This prevents the obstruction of the holes with particles. The medium diameter of the holes may range from 0.05 mm to 0.3 mm. The thickness of the protection section with at least one hole may be of the same order of magnitude as the diameter of the holes.
- In a further embodiment, the protection section is a thin membrane. The membrane is completely closed and blocks dirt, liquids and humidity. The thin membrane allows the transmission of sound with only little acoustic dampening. Therefore, the ratio between the diameter of the membrane and its thickness should be greater than 50, preferably greater than 100. For example, a membrane of 2 mm diameter should have a thickness of less than 40 µm, preferably less than 20 µm. A substantially round form is preferred.
- According to an embodiment, the toggle is arranged on the outward facing side of the first microphone protection cover. Like so, the user has a direct contact with the toggle that can be made from a specific material and the first microphone protection cover is sealing the inside of the housing completely in the region of the toggle. The direct contact with the toggle allows for the selection of a toggle material that the user perceives pleasing.

The toggle can be arranged in a recess in the protection cover that has an opening facing inwards and the toggle can be inserted and removed therefrom or the toggle can be moulded together with the protection cover and the material of the cover is partially or completely covering the entire surface of the toggle. The toggle being enclosed within the first microphone protection cover, prevents the pollution of the toggle region, i.e. the accumulation of dust, dirt or humidity below the toggle.
- According to another embodiment, there are two microphones and two corresponding protection sections. Two microphones that are spaced apart from each other allow a direction detection of the receiving sound. The central sealing section together with the two protection sections form an entity that covers and seals a large part of the inside of the housing, thereby improving the sealing effect and simplifying the assembly of the hearing device.
- In an embodiment, the channel extends from the microphone in a first direction beyond the position of the first microphone protection cover and then extends in a second direction to a corresponding microphone opening. The angular arrangement of the two sections of the channel gives an additional protection against pollution. The angle between the first direction and the second direction is in the range of 60 to 90 degrees. The bigger the angle, the lesser it is possible for pollutions to reach the region of the microphone protection cover.
- In another embodiment, the material of the first microphone protection cover is an elastic polymer, preferably silicone. Such a material is water repellent, is flexible and has good sealing properties.
- In yet a further embodiment, the material is an optically absorbing material. The material itself can be optically absorbing or the base material can comprise optically absorbing components. Preferably the material or the absorbing components can absorb UV radiation. The radiation protection reduces the aging rate of the microphones. According to an embodiment, the hearing device further comprises a second microphone protection cover, which is arranged between the microphone and the first microphone protection cover. The second cover provides an additional protection and can be of a different composition than the first cover. The second cover can comprise a woven or nonwoven fabric or any open-pore material. The second cover can comprise an adhesive area, preferably at its periphery or it can be self-adhesive.
- The features of the above-mentioned embodiments of the hearing device can be used in any combination, unless they contradict each other.
