Headphones with functions of multidirectional sensing, volume self-adjustment and light-sensation power off

Abstract

The invention relates to a pair of headphones with functions of multidirectional sensing, volume self-adjustment and light-sensation power off. The pair of 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; a solar cell panel is arranged on the outer side surface of the headphone band and connected with a power supply; 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, a photoelectric sensor is arranged between the magnetic blocks and connected with a radio module and the power supply through an MCU (micro control unit), and an output end of the radio module is connected with an audio output module; a noise monitoring module and a timing alarm module are arranged in the ear caps and control volume output of the audio output modules through the MCU respectively. The pair of headphones with the functions of multidirectional sensing, volume self-adjustment and light-sensation power off is simple in structure and convenient to store, occupies small space, has an automatic power-off function and is energy-saving and environment-friendly; real-time volume adjustment is adopted, and the comfort degree is increased.

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 or examination places in schools. Radio earphones generally adopt a head-mounted structure. When in use, the switch is activated and the frequency is adjusted for broadcast listening. Traditional radio earphones are powered on or off manually, which has the disadvantage of wasting power due to forgetting to turn off the power. When the existing radio earphones are not in use, the earmuffs on both sides close together under the elastic contraction of the elastic connecting band in the middle, but due to the large span of the connecting band, the occupied space of the earmuffs is larger; the output volume of the earphone must be Manual adjustment requires multiple adjustments when the environment changes, and the operation is cumbersome; the earphone uses a rechargeable battery or an ord...

Traditional radio earphones are powered on or off manually, which has the disadvantage of forgetting to turn off the power and causing power waste

When the existing radio earphones are not in use, the earmuffs on both sides close together under the elastic contraction of the elastic connecting band in the middle, but due to the large span of the connecting band, the occupied space of the earmuffs is larger; the output volume of the earphone must be Manual adjustment requires multiple adjustments when the environment changes, and the operation is cumbersome; the earphones use rechargeable batteries or ordinary storage batteries as power sources, and need to be frequently charged or replaced, and the cost is relatively high
