Abstract
(EN) Disclosed are an earphone wearing status detection method and device and an earphone. The method comprises: acquiring a type of an environment in which an earphone is located, wherein environment types comprise a noisy environment type and a non-noisy environment type; when the earphone is in a non-noisy environment, the earphone playing a preset audio signal; acquiring feedforward sound pressure and feedback sound pressure of the earphone so as to determine a difference between the feedforward sound pressure and the feedback sound pressure, wherein the feedforward sound pressure is sound pressure of a sound signal acquired by a feedforward microphone of the earphone, and the feedback sound pressure is sound pressure of a sound signal acquired by a feedback microphone of the earphone; and determining, according to a comparison result between the difference and a preset first threshold range corresponding to the environment type, whether the earphone is being worn in a standard manner.
(FR) L'invention concerne un procédé et un dispositif de détection d'état de port d'écouteur et un écouteur. Le procédé consiste : à acquérir un type d'un environnement dans lequel se trouve un écouteur, les types d'environnements comprenant un type d'environnement bruyant et un type d'environnement non bruyant ; lorsque l'écouteur est dans un environnement non bruyant, l'écouteur lit un signal audio prédéfini ; à acquérir une pression sonore prédictive et une pression sonore de rétroaction de l'écouteur de façon à déterminer une différence entre la pression sonore prédictive et la pression sonore de rétroaction, la pression sonore prédictive étant une pression sonore d'un signal sonore acquis par un microphone prédictif de l'écouteur, et la pression sonore de rétroaction étant une pression sonore d'un signal sonore acquis par un microphone de rétroaction de l'écouteur ; et à déterminer, en fonction d'un résultat de comparaison entre la différence et une première plage seuil prédéfinie correspondant au type d'environnement, si l'écouteur est porté de manière standard.
(ZH) 本发明公开了一种检测耳机佩戴状态的方法和装置、以及耳机。所述方法包括:获取耳机所处的环境类型,环境类型包括噪声环境类型和非噪声环境类型;当耳机处于非噪声环境类型时,耳机播放预设的音频信号;获取耳机的前馈声压和反馈声压,以确定前馈声压和所述反馈声压的差值;其中,前馈声压为耳机的前馈麦克风拾取的声音信号的声压,反馈声压为所述耳机的反馈麦克风拾取的声音信号的声压;根据差值与预设的与环境类型对应的第一阈值范围的比较结果,确定所述耳机的佩戴是否合格。
