Abstract

The invention provides a device and a method for forming a voice tube of an audiphone. The device comprises a forming board with a curved surface, wherein the curved surface has the same pre-determined forming curvature as a standard voice tube; the left and right sides of the curved surface are respectively provided with a row of positioning pressure springs; the left and right sides of a concave part in the middle section of the curved surface are respectively provided with an earplug connecting piece clamp spring and a forming groove; the earplug connecting piece clamp spring is opposite to an earplug connecting piece of the standard voice tube; the forming groove is adjacent to the earplug connecting piece clamp spring and positioned on the inner side of the earplug connecting piece clamp spring; and the groove width of the forming groove is matched with the diameter of the voice tube. The forming device and the forming method by using the forming device have the advantages of capability of processing a left voice tube and a right voice tube at one time, short heating and cooling time, high efficiency and no local deformation.

Description

【Technical field】 [0001] The invention relates to a hearing device, in particular to a forming device and a forming method of a sound tube in a behind-the-ear hearing aid (BTE). 【Background technique】 [0002] For a behind-the-ear hearing aid (BTE) worn behind the ear, the audio signal from the hearing aid must be transmitted to the ear canal through a sound guide tube (referred to as the sound tube) that meets the acoustic requirements, and one end of the sound tube must be reliably connected to the The other end of the earphone output port of the behind-the-ear hearing aid (BTE) should be connected to the earplug or ear mold that fits the wearer's ear canal, so that the wearer can comfortably hear the clear sound amplified by the hearing aid. [0003] In order to make the behind-the-ear hearing aid (BTE) comfortable and secure to wear, and to allow the connected earplugs or earmolds to reach the wearer's ear canal just accurately, the sound tube needs to have a fixed shape...
