A rechargeable battery temperature detection method adapted to an electronic system includes detecting a status of a processor of the electronic system when an external power is input to a power conversion module of the electronic system; determining whether a thermistor of the electronic system is conducted to a fuel gauge or a charge control circuit according to the state of the processor such that the fuel gauge or the charge control circuit determine a temperature sensing result via the thermistor. The thermistor is disposed adjacent to a rechargeable battery and has a resistance which varies with a temperature of the rechargeable battery. The temperature sensing result is related to the resistance.

Rechargeable battery temperature detection method, power management device and electronic system

A wireless ear phone and a sound broadcasting method thereof are provided. The wireless ear phone includes a first signal sensor, an electromagnetic signal transmitter, a second signal sensor and a controller. The first signal sensor generates an environment light detection result by detecting an environment light. The electromagnetic signal transmitter transmits an interruptible electromagnetic signal. The second signal sensor is disposed on a transmission path of the interruptible electromagnetic signal, and the second signal sensor generates an electromagnetic signal detection result by detecting whether the interruptible electromagnetic signal or the environment light is received. The controller enables or disables an operation of sound broadcasting of the wireless ear phone according to the electromagnetic signal detection result. When the wireless ear phone is put into an ear of a user, the transmission path is cut-off by the ear of the user.
