Abstract
A hearing device having at least one of an acoustical/electrical converter and an electrical/acoustical converter respectively with an acoustical input or output. The input or output, as the case may be, is linked to a coupling opening at the outer surface of the device via a channel. At least a part of the outer surface of the device is formed by a one-part shell. The shell defines an inner space of the device, with the channel being provided within and along the part of the shell and being formed within the material of the shell.
Claims14
A hearing device comprising:
- a one-part shell member forming at least a portion of an outer surface and of an inner surface towards an inner space of said device, said shell member forming a channel out of the material of said shell member, said channel being formed in and along said shell member embedded in said shell member over at least a major portion of the length of said channel over said major portion following a contour of said outer surface;
- and
- at least one of an acoustical/electrical converter and an electrical/acoustical converter including an acoustical input or output, respectively, wherein
- said input or output is acoustically linked to a coupling opening via said channel forming an acoustic path from said input or output to said coupling opening at an outer surface of said device and adapted to be exposed to ambient or an ear canal of an individual wearing said hearing device but not both, and further wherein
- said channel is tuned to have specific acoustical characteristics.
A hearing device comprising an acoustical/electrical converter with an acoustical input being linked by means of a channel to a coupling opening arrangement exclusively at an outer surface of said device adapted to be exposed to ambient when an individual wears said hearing device, said device having a unitary shell member forming said outer surface and defining an inner space distinct from said channel, said channel being a part of said shell member formed by and embedded in the material of said shell member along a major portion of the length of said channel provided in and along said shell member with the major portion of said length following a contour of said outer surface.
A hearing device comprising:
- a one-part shell member forming at least a portion of an outer surface and of an inner surface towards an inner space of said device, said shell member forming a channel out of the material of said shell member, said channel being formed in and along said shell member embedded in said shell member over at least a major portion of the length of said channel, said major portion of said channel following a contour of said outer surface;
- an electrical/acoustical converter including an acoustical output, wherein
- an acoustic path is formed from said output to a coupling opening in said shell member and comprises said channel.
