Title:
HEADSET OSCILLATOR DETECTION DEVICE, SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2014/075639
Kind Code:
A1
Abstract:
Disclosed are a headset oscillator detection device, system and method. The device of the present invention is suitable for checking a headset oscillator, and is disposed at the wearing position of the headset during checking. The device comprises an acceleration sensor and a signal conversion module mutually connected; the acceleration sensor is used to detect the acceleration information of the wearing position when the headset plays a specified audio frequency, and convert the acceleration information into a voltage signal to be outputted to the signal conversion module; and the signal conversion module is used to convert the received voltage signal into a digital signal to be outputted, so as to determine whether the oscillation amplitude of the headset oscillator is up to standard according to the outputted digital signal. The technical solution of the present invention solves the problem that headset oscillator checking is currently conducted manually in a cumbersome and laborious manner.
