Audio and/or vibration test carrying out device e.g. antenna coupler, for mobile telephone, has sound receiver receiving signal delivered via speaker of telephone over impact sound produced by signal during audio and/or vibration test

摘要

The device i.e. antenna coupler (1), has a sound receiver i.e. piezoelectric or piezoceramic element (18), receiving a signal delivered via a speaker of a mobile telephone over impact sound produced by the signal during an audio and/or vibration test at the mobile telephone. The signal is selected from one of an audio signal such as audio test signal, call signal and bell sound, and a signal produced by vibration of the mobile telephone. The receiver is attached within a housing (2) of the device. The audio test signal is provided as a monofrequent audio signal with predetermined frequency. An independent claim is also included for a method for carrying out of audio and/or vibration tests at a mobile telephone.
