Abstract

The invention discloses an earphone wearing detection method and device, and the method comprises the steps: obtaining the difference between sound signals detected by an in-ear microphone and an out-of-ear microphone; and determining the wearing state of the earphone based on the difference of the sound signals, wherein the wearing state comprises a non-wearing state and a worn state. By acquiring the difference of the sound signals detected by the in-ear microphone and the out-of-ear microphone and determining the wearing state of the earphone based on the difference of the sound signals, the wearing state of the earphone can be determined through traditional signal processing without adding an additional sensor, and the hardware cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of earphones, in particular to a method and a device for detecting earphone wearing. Background technique [0002] At present, there are in-ear detection solutions on the market. The main way to achieve this is to add sensors. The most common one in the market is the optical solution. By punching holes on the surface of the earphones, the optical sensor judges whether to wear them by detecting the light input. Some of them will use capacitive detection solutions. , through the multi-channel capacitive sensor, the capacitance value in the earphone detection area is obtained, and then the area contact value is calculated to judge the wearing state of the earphone. Regarding the detection of the wearing state, mainly by controlling the audio output device to output a fixed frequency or preset audio signal, the audio input device receives the audio signal, and judges the difference between the sound pressure lev...
