Abstract

The present invention discloses digital headsets. The digital headset comprises a temperature detection module (U1), a processing module (U2) and a power switch (S1) connected on a power supply loop of the digital headset. The temperature detection module (U1) is set for detecting a current temperature of a circuit board welded with the temperature detection module (U1). The processing module (U2) is set for comparing the current temperature with a reference temperature and controlling a state of the power switch (S1) according to a comparison result. The digital headset can be effectively protected from being burned due to heating caused by various abnormal operations.

Description

technical field [0001] The invention relates to the field of earphones, and more specifically, the invention relates to a digital earphone provided with a temperature sensor. Background technique [0002] The existing headphone circuit protection method is mainly based on the overvoltage or overcurrent detection of the electrical signal for protection. When the current exceeds the set current or the voltage exceeds the set voltage, the headphone is automatically powered off to protect the headphone. [0003] However, the existing solutions using overvoltage or overcurrent protection have the following disadvantages: only the circuits with added protection circuits can be protected; if multiple circuits are protected, many electronic components are used and a large space is occupied. [0004] The heat generated by the related components due to the short circuit of the earphone or other abnormalities is manifested in the circuit in the form of heat energy. Therefore, the temp...
