Problems solved by technology

This digital implementation complicates the test layer for development and manufacturing
This is due to: i) the need to pass configuration and control messages between the measurement system and the headphone device under test, ii) the need to collect and integrate data from a spatially extended and weakly connected test system, and iii) the difficulty of arranging time-synchronized data. is needed to compute coherent estimates of statistics across the test system, thus creating complexity

Embodiment Construction

[0058] The present invention proposes a new reciprocal relationship between the earphone device and the test system for detecting the earphone device. This relationship is relevant when there is only a pure digital application interface between the headset device itself and the media or other data sources of the end user using the headset device in the terminal application. When the application interface is the device under test during the test and configuration phase of its manufacture, the application interface will be used as the only link between the headset device and the new measurement system that is based on the teachings given by the present invention Specially developed. The present invention further teaches a new supplementary method for programming this active earphone device to include a "test mode". Compared with the prior art method, the new supplementary method and the new measurement system can achieve a deeper level Integration. This integration accommodates...

Abstract

An earphone device / test station pairing (1, 2) comprises an earphone device (1) comprising at least one electroacoustic driver (32, 33, 34); a digital module (31) including a processor module; a digital interface configured to connect the earphone device (1) to a media / communications device having a digital output. A test station (2) comprises at least one transducer (40, 42, 6), and the test station (2) is operative to communicate with the earphone device (1) via the digital interface to allow data transmission between the earphone device (1) and the test station (2) during a test / configuration procedure. The earphone test system also comprises a test module (4) for performing automated testing of the earphone device (1) when mounted on / connected to the test station (2).

Description

Technical field [0001] The present invention relates to a system for realizing earphone device testing, in particular but not limited to a system capable of testing earphone devices with active noise reduction (ANR) function. Background technique [0002] Earphones (for example, headphone or ear-hook earphones are connected together by a headband to form an over-ear earphone type or are configured to be placed at the entrance of the user’s ear or in the ear canal), in It is well known in the art. Active headphone systems including active headphone drivers are used to provide high-level active features such as active noise reduction (ANR) or binaural monitoring, which are also well known in the art. ANR technology provides the ability to eliminate unwanted external sounds and / or unwanted sounds (at least some functional parts) sensed by the internal sensor microphone through feedback control. The development and manufacturing of active headsets and in-ear headphones, especially ...
