Abstract
A method for manufacturing a hearing device is disclosed. The hearing device comprises a speaker, a first chamber, and a sound channel arranged between the first chamber and the surroundings of the hearing device or a second chamber. An element of a thermoplastic material being in a solid state is arranged in the sound channel. A laser light is applied to the element to thereby activate the element to change from the solid state to a liquid state. The element then changes from the solid state to the liquid state filling out a cross-section of the sound channel and thereby sealing the sound channel. Finally, cooling of the element is allowed leading to a change of the element from the liquid state to solid state while filling out the cross-section of the sound channel.
Claims13
A method for manufacturing a hearing device, the hearing device comprising—a speaker, a microphone, one or more wires interconnecting the speaker and the microphone, a first chamber, and a sound channel arranged between the first chamber and a second chamber, wherein the speaker is arranged in the first chamber and the microphone is arranged in the second chamber the method comprising:
- arranging an element of a thermoplastic material in the sound channel, the element being in a solid state;
- arranging the one or more wires in the sound channel and through the element:
- forming at least a top part of said sound channel of a light transmissible material capable of passing laser light therethrough;
- applying a laser light through said top part to the element to thereby activate the element to change from the solid state to a liquid state;
- sealing the sound channel by means of the element changing from the solid state to the liquid state thereby filling out a cross-section of the sound channel;
- allowing cooling of the element thereby a change of the element from the liquid state to solid state while filling out the cross-section of the sound channel, wherein the one or more wires comprise an insulation material transparent to the laser light.
