1. An earbud with temperature sensing, comprising:
a housing defining a first opening, a second opening and a third opening;
a speaker disposed within the housing and oriented so that audio emitted by the speaker exits the housing through the first opening defined by the housing;
a first temperature sensor positioned along an interior surface of the housing and aligned with the second opening in the housing for non-contact temperature sensing;
a second temperature sensor positioned along the interior surface of the housing and aligned with the third opening in the housing for non-contact temperature sensing,
wherein, in response to the earbud being positioned for use within an ear of a user, the second opening aligns with one of an inner side of the tragus close to the ear canal, the cavum conchae, and an inner edge of the antitragus, and the third opening aligns with the cheek close to the ear, such that the first temperature sensor and the second temperature sensor detect a body temperature of the user through the second opening and the third opening, respectively, and the body temperature is estimated by considering sensor data of the first temperature sensor and the second temperature sensor.
