Abstract

The invention relates to a portable electronic device which comprises a power module, a sampling circuit, a signal processing module, a music playing module provided with a loudspeaker and a temperature sensor, wherein the temperature sensor is electrically connected with the sampling circuit and senses the body temperature of a user, the sampling circuit samples the temperature transferred by the temperature sensor, and the signal processing module automatically regulates the volume of the loudspeaker according to body temperature variation of the user.

Description

technical field [0001] The invention relates to a portable electronic device, in particular to a portable electronic device which can automatically adjust the volume. Background technique [0002] In order to create a good sleep environment, many people often use portable electronic devices such as MP3, radio or mobile phones with music playing function to play some soft music to help sleep before falling asleep. [0003] But in the process of falling asleep, it is often necessary to constantly adjust the playback volume of the portable electronic device to ensure that the volume can be heard by people to feel the hypnotic effect, and it will not affect normal sleep because the volume is too high. It is difficult to grasp the volume, which is very inconvenient. In addition, the user may forget to turn off the portable electronic device when falling asleep, causing it to consume more power and affecting its performance and service life.
