The invention provides a temperature detection method. The method is applied to a first electronic device. The first electronic device and a second electronic device are matched to be used. The second electronic device comprises a first device, a first switch and a thermistor, specifically, the first switch is connected with the thermistor in series and is connected a branch circuit where the first device is located in parallel. The temperature detection method includes the steps that the first resistance value, generated when the first switch is in a turn-off state, of the second electronic device is obtained, the second resistance value, generated when the first switch is in the turn-on state, of the second electronic device is obtained, the current resistance value of the thermistor is determined according to the first resistance value and the second resistance value, the current temperature corresponding to the resistance value of the current thermistor is obtained, and the problem that in the prior art, a mobile electronic device is not provided with the environmental temperature detection function is solved.
Description
technical field [0001] The present invention relates to the communication field, and more specifically, relates to a temperature detection method, device, [0002] circuit and an electronic device. Background technique [0003] At present, the types and applications of mobile electronic devices are in a diversified development trend. For example, computers have changed from heavy notebook computers to ultra-thin notebooks, and then to "ultrabooks". For another example, the mobile phone has changed from the basic "receive and send" function to the candy bar smart phone, and then to the touch screen smart phone with various applications. [0004] In addition, with the rapid development of mobile communication technology, mobile electronic devices with voice functions are used by more and more consumers. At the same time, earphones have become one of the indispensable communication accessories in daily work and life. . [0005] Specifically, driven by consumer demand, there ...
