Earphone and wearing detection device thereof

Abstract

The invention discloses an earphone and a wearing detection device thereof. The detection device comprises an induction panel used for forming a packaging metal shell of a battery, a detection chip with an input end connected with the induction panel, and a control chip connected with an output end of the detection chip, wherein the battery is arranged in an ear handle of the earphone; the detection chip is used for detecting an induction signal of the induction panel, and determining the wearing state of the earphone according to the induction signal; and the control chip is used for adjusting the working state of the earphone according to the wearing state. When a user wears the earphone, the ear handle of the earphone is in contact with the skin of the user, a capacitance effect is formed between the induction panel and the user skin and an induction signal is generated, the detection chip determines the wearing state of the earphone through the induction signal, and the control chip adjusts the working state of the earphone according to the wearing state. According to the wearing detection device of the earphone provided by the invention, the packaging metal shell is multiplexed into the induction panel, miniaturization of the earphone is facilitated, and the detection sensitivity and reliability of the wearing state are improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of portable listening devices, in particular to an earphone and a wearing detection device thereof. Background technique [0002] With the development of science and technology, the use of earphones in people's lives is becoming more and more common. Among them, Bluetooth earphones are becoming more and more popular, and binaural wireless earphones are also gradually emerging, and the integration is getting higher and higher, and the volume is getting smaller and smaller. In order to achieve longer battery life and better user interaction experience, these headsets are usually equipped with a wearing detection function. [0003] At present, the wearing detection function is usually realized by means of infrared, laser or capacitive detection, no matter which method needs to take up a considerable amount of space, among them, the use of infrared detection will also affect the appearance ...

Problems solved by technology

[0003] At present, the wearing detection function is usually realized by means of infrared, laser or capacitive detection, no matter which method needs to take up a considerable amount of space, among them, the use of infrared detection will also affect the appearance design, capacitive detection needs to be set Touch the sensing panel, and detect the sensing signal obtained by the touch sensing panel through the detection chip. However, the touch sensing panel in the capacitive detection usually requires additional space for setting, which is not conducive to the miniaturization of the earphone, and because the internal space of the earphone is limited, Therefore, the sensing area of ​​the touch-sensitive panel will be limited, and the detection sensitivity will be limited.
