Light-sensation power off type headphones with automatic volume adjustment function

Abstract

The invention relates to a pair of light-sensation power off type headphones with an automatic volume adjustment function. The pair of light-sensation power off type 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, an elastic band is connected to the connected position of the two half parts of the headphone band and is arranged on the inner side of the headphone band, and a solar cell panel band is arranged on the outer side surface of the headphone band and connected with a power supply; the ear caps are rotationally arranged at the two ends of the headphone band by the aid of second rotating shafts; magnetic blocks and a photoelectric sensor are arranged on the inner side surface of each ear cap, an acceleration sensor is arranged in one ear cap, the acceleration sensor and the corresponding photoelectric sensor are 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. The pair of light-sensation power off type headphones with the automatic volume adjustment function is simple in structure, convenient to store, energy-saving and environment-friendly and occupies small space.

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 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 relatively large; the earmuffs are powered by batteries, The battery needs to be replaced frequently, and its environmental protection is not high. The existing earphones also l...

Problems solved by technology

After the traditional radio earphones are used up, they need to manually turn off the power, 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 relatively large; the earmuffs are powered by batteries, The battery needs to be replaced frequently, and its environmental protection is not high

The existing earphones still lack the function of automatic volume adjustment, which has a certain impact on the hearing of the human body
