Abstract: This application provides an earphone and a temperature measurement method for the earphone. The earphone may include an earbud and a first temperature sensor. The earbud includes an earbud housing and a sound outlet hole, first accommodating space is formed by enclosing the earbud housing, the sound outlet hole may be disposed on the earbud housing, and the sound outlet hole connects the first accommodating space and external space of the earphone, so that the earphone can emit sound through the sound outlet hole. Therefore, in this application, the first temperature sensor may be located in the first accommodating space, and may be disposed on an outer side of a hole channel of the sound outlet hole, to avoid impact of the first temperature sensor on sound outlet effect of the sound outlet hole. In addition, the sound outlet hole may be disposed directly opposite to a periosteum of a human ear. Therefore, a temperature of the periosteum can be transferred to the sound outlet hole. In addition, the temperature of the periosteum of the human ear is close to a core temperature of a human body. Based on this, the first temperature sensor can be in thermally conductive contact with the sound outlet hole, so that the temperature of the periosteum can be transferred to the first temperature sensor through the sound outlet hole, and the first temperature sensor can obtain a more accurate human body temperature through measurement.
