Embodiment Construction

[0056] figure 1 A prior art BTE hearing aid 10 is shown in perspective view. The BTE hearing aid 10 includes a hearing aid housing 12, a sound tube 14 having a pre-formed shape for conducting sound from the hearing aid housing 12 to the ear canal (not shown), and an earpiece attached to the sound tube for insertion into the ear canal. 16.

[0057] The hearing aid housing 12 is configured to be worn behind the user's ear and contains a battery, a microphone, a processor and a receiver (not shown) for generating sound input into the sound tube 14 .

[0058] The pre-formed shape of the sound tube 14 includes a first bend 18 extending from the shell over the top of the user's ear when the user wears the hearing aid 10 and a second bend 20 extending from the outside of the ear into the user's ear canal.

[0059] Earpiece 16 is configured to fit within the ear canal and, preferably, allows sound from inside and outside the ear to pass through the ear canal surrounding the earpiece...

Abstract

The present invention relates to a simplified manufacturing method for provision of a sound tube with a pre-formed shape, especially a sound tube for use in a BTE (BehindThe-Ear) hearing aid utilizing a holder with an external surface for imparting the shape of the surface to the sound tube, a first attachment element that is adapted to receive and hold a first connector at a first end of the sound tube, and a second attachment element that is adapted to receive and hold a second connector at a second end of the sound tube thereby keeping the sound tube in abutting contact with at least parts of the external surface whereby the external surface imparts the shape of the surface to the sound tube.

Description

technical field [0001] The present invention is concerned with providing a simplified manufacturing method of an acoustic tube having a pre-formed shape, in particular for use in BTE (behind the ear) hearing aids. Background technique [0002] In behind-the-ear hearing aids, the sound signal travels as an acoustic signal from a receiver located in the hearing aid housing behind the ear through an acoustic tube into the ear canal, as is well known in the art. [0003] To securely and comfortably position the sound tube within the ear canal, an earpiece, housing, or earmold is provided as an accessory for the sound tube and inserted into the user's ear canal. [0004] Typically, the first end of the sound tube is attached to a first connector for coupling the sound tube to the BTE housing containing the hearing aid electronics, and the second end of the sound tube is attached to a second connector for coupling the sound tube to the earpiece. Connector. The sound tube is usua...
