Referring to fig. 11, based on the earphone box 1 and the wireless earphone 2 provided in the present application, the power consumption mode of the wireless earphone 2 may also be adjusted: when having the electricity on wireless earphone 2's POGO PIN3, the power supply of bluetooth chip is just got from the POGO PIN, when the consumption ratio of bluetooth chip is lower, when if the chip gets into the dormancy, also when flowing through the POGO PIN2 of earphone box 1 and going up resistance current less, the voltage drop ratio that produces on sampling resistor R1 is smaller, it is possible the maloperation to come in and go out the box detection this moment, for this reason, through wireless earphone 2 at first through detecting the 5V on the POGO PIN, judge whether to put into earphone box 1, whether later get into the low power consumption mode according to the state of the switch cover of earphone box 1: the earphone box 1 is opened, the Bluetooth chip does not enter a low power consumption mode, and the current consumed by the Bluetooth chip is kept at a higher value so as to ensure that the earphone box is normally opened and closed; earphone box 1 closes the lid, and the bluetooth chip can get into low-power consumption mode as required. That is, according to 5V and whether the opening and closing state of the earphone box 1 enters the low power consumption mode, when there is 5V (put into the earphone box) and the earphone box 1 is opened, the wireless earphone 2 enters the non-low power consumption mode. Once the earphone box 1 is closed, the wireless earphone 2 can enter a low power consumption mode, so that electricity can be saved.
Therefore, the earphone box 1 and the wireless earphone 2 provided by the embodiment of the application obviously reduce the cost of products. The detection of the in-out box is realized by adopting the mode of voltage acquisition by the ADC, the cost is low, and compared with three detection modes in the related technology, the detection method has the cost advantage, and particularly has great cost advantage compared with an infrared proximity sensor scheme; meanwhile, the size and the structural complexity of the product are obviously reduced by the earphone box 1 and the wireless earphone 2 in the embodiment of the application. And the ADC adopted for collecting the voltage only needs to add a plurality of capacitance-resistance devices on the box printed circuit board, the structural design complexity is low, and compared with hall and the like, large-size devices such as magnets do not need to be added on the earphone. In addition, earphone box 1 and wireless earphone 2 that this application embodiment provided have shown the reliability that has promoted the product, compare for example in dabbing switch detection scheme and have shown the reliability that has promoted the reliability of detection function and the shell protection reliability of earphone box.
