Abstract

The invention belongs to the field of electronic products, in particular relates to an earphone with an automatic sensing function. The earphone comprises an earphone plug, a sensing unit, a first switching unit, a second switching unit, a microphone unit, a control unit and an earphone unit, wherein the earphone plug is connected with a jack and is used for receiving a direct-current power supply signal, a grounding signal and an alternating-current sound signal; the sensing unit is respectively connected with the earphone plug, the first switching unit, the second switching unit and the microphone unit; and the control unit is respectively connected with a first switching unit, the second switching unit and the earphone unit and is used for controlling the first switching unit and the second switching unit to be in a conducting state or a stopping state; and the earphone unit is connected with the control unit through an earphone plug and is used for receiving the alternating-current sound signal and the grounding signal from the control unit. The earphone with the automatic sensing function, disclosed by the invention, is not limited by signal configuration of an earphone socket and is universally applied to various electronic devices.

Description

technical field [0001] The invention belongs to the field of electronic products, in particular to an earphone with an automatic detection function. Background technique [0002] An earphone is a sound output device through which a user can receive sound signals without disturbing others. Therefore, many electronic devices are equipped with earphone jacks to output sound through earphones. [0003] Headphones can be divided into three-section type and four-section type according to the different connectors. A four-section earphone includes two speakers (left and right channels), a microphone, and a ground terminal; a three-section earphone only includes two speakers (left and right channels) and a ground terminal. [0004] However, due to the different preferences of various manufacturers, the signal configuration of the headphone socket is not uniform. Therefore, when purchasing electronic devices, users often need to choose the headphones provided by the original factory...
