Smart headphones based on photoelectric control

Abstract

The invention relates to a pair of smart headphones based on photoelectric control. The pair of smart headphones comprises a headphone band and ear caps at two ends of the headphone band, wherein the headphone band is formed by connecting two half structures with a first rotating shaft, and an elastic band is connected to the connected position of the two half parts of the headphone band; the ear caps are rotationally arranged at two ends of the headphone band by the aid of second rotating shafts; magnetic blocks are vertically arranged on the inner side surface of each ear cap, and a transmitting terminal and a receiving terminal of a photoelectric sensor are arranged between the vertically arranged magnetic blocks; each photoelectric sensor is connected with a radio module and a power supply through an MCU (micro control unit), and the output end of the radio module is connected with an audio output module. The pair of smart headphones based on the photoelectric control is simple in structure; the headphone band and the ear caps can rotate around the rotating shafts respectively, the space occupied by the headphones is reduced, and the headphones are convenient to store; with the arrangement of the photoelectric sensors, the automatic power-off function of the headphones is realized, electric power waste is reduced, and accordingly, the pair of smart headphones is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the field of earphones, in particular to radio earphones. Background technique [0002] Radio earphones are widely used in people's daily life. Radio earphones generally adopt a head-mounted structure. When in use, the switch is activated and the frequency is adjusted to listen to the broadcast. After the traditional radio earphones are used up, the power supply needs to be turned off manually, which has the disadvantage of forgetting to turn off the power supply and causing waste of electric energy. When the existing radio earphone is not in use, the earmuffs on both sides close together under the elastic contraction of the elastic connecting band in the middle, but because the span of the connecting band is relatively large, the occupied space of the earmuffs is relatively large. Contents of the invention [0003] In view of the above-mentioned shortcomings of traditional radio earphones, the applicant provides a smart ear...
