Abstract
(EN)
A method for a terminal to detect a headset status, and the terminal. A processor closes a passage for performing an audio signal output on a second headset, detects electrical signals of a first audio output end and a third audio output end of a first headset, then determines the frequency value of a low frequency resonance point of the first headset according to the electrical signals of the first audio output end and the third audio output end, and judges whether the first headset is in an in-place status according to the frequency value of the low frequency resonance point. As long as the electrical signals of a first audio output end and a third audio output end are detected, whether a headset is in place can be determined according to the change of the electrical signals. Thus, the status of a first headset can be detected simply and quickly.

L'invention porte sur un procédé permettant à un terminal de détecter un état de casque, et sur le terminal. Un processeur ferme un passage permettant d'effectuer une sortie de signal audio sur un deuxième casque, détecte des signaux électriques d'une première extrémité de sortie audio et d'une troisième extrémité de sortie audio d'un premier casque, puis détermine la valeur de fréquence d'un point de résonance basse fréquence du premier casque en fonction des signaux électriques de la première extrémité de sortie audio et de la troisième extrémité de sortie audio, et juge si le premier casque est dans un état en place selon la valeur de fréquence du point de résonance basse fréquence. Tant que les signaux électriques d'une première extrémité de sortie audio et d'une troisième extrémité de sortie audio sont détectés, il est possible de déterminer si un casque est en place selon les variations des signaux électriques. Ainsi, l'état d'un premier casque peut être détecté de façon simple et rapide.

终端检测耳机状态的方法及终端,处理器关闭对第二耳机进行音频信号输出的通路,然后检测该第一耳机的第一音频输出端和第三音频输出端的电信号,然后根据所述第一音频输出端和第三音频输出端的电信号确定第一耳机的低频谐振点的频率值;根据所述低频谐振点的频率值确定第一耳机是否处于在位状态。只需检测该第一音频输出端和第三音频输出端的电信号,然后根据电信号的变化即可确定耳机是否在位,因此,可以简单快速检测第一耳机的状态。
