Problems solved by technology

Although this method of switching the headphone circuit by identifying the voltage at both ends of the microphone and controlling its own switch can realize the switching of the headphone circuit, but due to the need to accurately identify the voltage at both ends of the microphone and cooperate with the voltage control switch to switch, if there is voltage instability or cooperation process Problems such as time gaps will cause the short-term function failure of the earphones and affect the use, and the voltage-controlled switch cannot completely disconnect other circuits when using one earphone circuit, which may also cause the earphone function to fail

Abstract

The invention discloses a smart earphone, comprising a depletion type isolating switch and at least two volume control circuits. The depletion type isolating switch is electrically connected with the at least two volume control circuits. The at least two volume control circuits correspond to different smart earphone volume control modes. The depletion type isolating switch is selectively switched to the volume control circuit which outputs a high level according to whether the high level output by one of the at least two volume control circuits is received or not.

Description

technical field [0001] The invention relates to an intelligent earphone, in particular to an intelligent earphone capable of automatically selecting and switching volume control loops. Background technique [0002] With the popularity of music and video playback equipment, people's entertainment life has been enriched. At present, existing music and video playback devices are mainly based on the ios system and the Android system, thus smart earphones that can be applicable to the ios system and the Android system are also emerging. [0003] Patent CN204616061U discloses an earphone control device for an intelligent mobile device, which is set in an intelligent earphone. Please refer to figure 1 , figure 1 It is a schematic circuit diagram of an earphone control device for a smart mobile device in the prior art. The device enables the earphone control device for a smart mobile device to switch between the ios volume control loop and the Android volume control loop by switc...
