The present invention discloses an apparatus, system and method for charging and turning on an earphone. The apparatus includes a spring piece, a Hall sensor, a microcontroller, a boosted circuit and a turn-on circuit. The spring piece is electrically connected to the putted earphone. The Hall sensor is used to sense whether the earphone is far away from or close to the Hall sensor, and transmits a first sensing signal to the microcontroller when the Hall sensor senses that the earphone is close to the Hall sensor and transmits a second sensing signal to the microcontroller when the Hall sensor senses that the earphone is far away from the Hall sensor. The microcontroller controls the boosted circuit to charge the earphone when the microcontroller receives the first sensing signal, and controls the turn-on circuit to turn on the earphone when the microcontroller receives the second sensing signal. According to the invention, the simple detection for earphone charging is realized, the complex structure is replaced by the Hall element, the key design is simplified, and the reliability and easy operability for charging detection are improved. The turn-on circuit can turn on the earphone when the earphone is separated from a charging base seat so as to simplify the user operation, improve the convenience, and improve the user experience for the product.
Description
technical field [0001] The invention relates to the field of bluetooth earphones, in particular to an earphone charging and starting device, system and method. Background technique [0002] At present, Bluetooth headsets are developing in the direction of miniaturization and convenient operation. The Pogo pin design saves the space for the USB connector on the headset, and the charging part is made into a separate charging base, which can be used as a power source to charge the headset. At the same time, there are many ways to detect and turn on the charging of the headset. The more traditional method is to detect the charging of the earphone through the handshake action between the earphone and the base, and the boot part is equipped with a separate button. Closure of the charging base. The design of the button will also reduce the reliability of charging detection and increase the difficulty of structural design. Contents of the invention [0003] In order to solve th...
