Intelligent adjustment type headphones with photoelectric automatic power off function

Abstract

The invention relates to a pair of headphones with a photoelectric automatic power off function. The headphones comprise 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 part of the two half parts of the headphone band; the ear caps are rotationally arranged at two ends of the headphone band through a second rotating shaft; magnets and a photoelectric sensor are arranged on the inner side surface of each ear cap, an acceleration sensor is arranged in one ear cap, each photoelectric sensor and the acceleration sensor are connected with a radio module and a power supply through a MCU (micro control unit), and an output end of the radio module is connected with an audio output module; a setter is arranged in the side surface of one ear cap. The headphones occupy small space and are convenient to store; the photoelectric sensors are arranged, so that the automatic power off function of the headphones is realized, electric power waste is reduced, and the headphones are energy-saving and environment-friendly; the acceleration sensor is adopted to automatically adjust volume of the headphones, the optimal volume of the headphones is guaranteed in real time, and hearing protection for ears is facilitated; the independent setter is arranged to facilitate function setting of the headphones.

Description

technical field [0001] The invention relates to the field of earphones, in particular to head-mounted 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 existing earphones lack volume The automatic adjustment function cannot adapt to the ear with the best volume; the setting buttons of the exist...

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 existing earphones lack volume The automatic adjustment function cannot adapt to the ear with the best volume; the setting buttons of the existing earphones are all set on the side of the earmuffs, and the earphones need to be removed when setting, which is troublesome to operate
