Abstract

The application relates to a test device for a speaker module of a listening device, the speaker module comprising a speaker unit for converting an electric output signal to an output sound. The application further relates to a test system. An object of the present application is to provide an alternative scheme for identifying a receiver (speaker) in a listening device, e.g. a hearing aid. The problem is solved in that the test device being a separate device adapted for being electrically connected to the speaker module in a test situation, but not during normal operation of the listening device. An advantage of the invention is that it provides a flexible alternative to a receiver identification solution that is integrated into the listening device. The invention may e.g. be used in hearing aids, headsets, ear phones, active ear protection systems, telephone handsets (cellular or fixed line), etc.

Description

technical field [0001] The present application relates to the characterization of a module in a listening device, such as a hearing aid, the module comprising a loudspeaker. This module is referred to below as a "speaker module" (in this application the term "speaker" is used interchangeably with the terms "receiver" and "speaker unit"). The present application relates in particular to a testing device for a speaker module of a listening device, the speaker module comprising a speaker unit for converting an electrical output signal into an output sound. [0002] The present application also relates to a testing system comprising a testing device and a loudspeaker module, a fitting system and testing device combination, and a testing device and listening device combination. The present application also relates to a data update device for transferring data to a listening device, and to a combination of a test device and a data update device. [0003] The invention can be used,...
