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.
